Rationale:
In IVF, also referred to as “test tube babies,” the egg is fertilized with sperm in a petri dish in
the lab and then placed into the women’s uterus.
54. In an effort to become pregnant after many years of trying, more and more couples are
turning to ________, which involves the removal of mature eggs from a female’s ovary and
fertilizing them with sperm in a laboratory before surgically implanting them in the woman’s
uterus.
a. gamete intrafallopian transfer (GIFT)
b. embryo transplant
c. zygote intrafallopian transfer (ZIFT)

TRUE-FALSE
1. Acceptance of the use of chloroform for childbirth grew rapidly when Queen Victoria
demanded and received chloroform during the birth of her eighth child in 1853.
Answer: True
Rationale:
Queen Victoria's use of chloroform during childbirth in 1853 is historically documented. Her
endorsement of anesthesia during labor helped to popularize its use in obstetrics, leading to
greater acceptance and adoption of pain relief methods during childbirth.
2. Among women of childbearing age in the U.S., over 4 million define themselves as
“voluntarily childless.”
Answer: True
Rationale:
The term "voluntarily childless" refers to individuals, typically women, who have chosen not
to have children despite being of childbearing age. As of the latest statistics available, over 4
million women in the United States self-identify as voluntarily childless, indicating a
significant portion of the population has made this decision for various personal, social,
economic, or environmental reasons.
3. Most women will have approximately 35 to 40 fertile years between menarche and
menopause.
Answer: True
Rationale:
Menarche marks the onset of menstruation, typically occurring during adolescence, while
menopause represents the cessation of menstruation, usually in middle age. The average age
of menarche is around 12 to 13 years old, and menopause typically occurs around age 45 to
55. Therefore, most women will have approximately 35 to 40 years of reproductive potential
between menarche and menopause.
4. When the ovum is in the uterus, the woman is “officially” fertile.
Answer: False
Rationale:
Fertility refers to the ability to conceive or become pregnant, which is not solely determined
by the presence of an ovum in the uterus. Fertility is influenced by various factors, including
the menstrual cycle, ovulation, sperm viability, and the timing of sexual intercourse relative
to ovulation. While the presence of an ovum in the uterus during ovulation increases the
likelihood of conception, fertility extends beyond this specific moment in the reproductive
process.
5. In health class, Greg learns about sperm production, including the fact that sperm cells are
produced in the testicles.
Answer: True
Rationale:
Sperm production, known as spermatogenesis, occurs within the testes (testicles) of the male
reproductive system. Sperm cells are generated through a process of cellular division and
differentiation within structures called seminiferous tubules, located within the testes. After
maturation, sperm cells are stored in the epididymis before being ejaculated during sexual
intercourse.
6. On average, somewhere between 400,000 and 500,000 sperm cells may be contained in a
single ejaculation.
Answer: False
Rationale:
The average volume of semen ejaculated during a single ejaculation typically contains
millions of sperm cells. Estimates vary, but it's generally believed that an average ejaculate
may contain anywhere from 40 million to 600 million sperm cells, with variations based on
individual factors such as age, health, and fertility.
7. Sue wonders if she will ever get pregnant. Her odds of getting pregnant are 1 in 5 from a
single act of intercourse.
Answer: False
Rationale:
The likelihood of pregnancy from a single act of unprotected intercourse varies depending on
factors such as timing relative to ovulation, fertility of both partners, and the effectiveness of
contraception (if used). While the chances of pregnancy from a single act of intercourse are
not guaranteed, they are generally higher than 1 in 5, especially if intercourse occurs during
the woman's fertile window, which is typically around the time of ovulation.
8. Immediately after the first sperm successfully penetrates the ovum’s outer membrane,
biochemical changes are triggered in the ovum creating a barrier that effectively blocks any
other sperm cell from entering.
Answer: True
Rationale:
After the first sperm successfully penetrates the ovum's outer membrane (a process known as
fertilization), biochemical changes occur within the ovum to create a barrier, preventing
additional sperm cells from entering. This process, called the zona reaction or zona pellucida
reaction, ensures that only one sperm cell fertilizes the ovum, preventing polyspermy
(fertilization by multiple sperm cells), which could result in genetic abnormalities.
9. The third trimester of pregnancy is marked by an increase in the rate of growth of the fetus.
Answer: True
Rationale:
The third trimester of pregnancy, which spans from weeks 28 to 40, is characterized by rapid
fetal growth and development. During this period, the fetus undergoes significant increases in
size, weight, and organ maturation in preparation for birth. The third trimester is a critical
phase of pregnancy when the fetus reaches viability (the ability to survive outside the womb)
and continues to mature in preparation for delivery.
10. “Silent miscarriages” occur so early in the pregnancy that the woman is unaware that she
is pregnant.
Answer: True
Rationale:
A silent miscarriage, also known as a missed miscarriage or missed abortion, occurs when a
woman experiences a miscarriage but does not have any noticeable symptoms or signs of
pregnancy loss. In some cases, the fetus may stop developing or die very early in pregnancy,
often before the woman is aware of her pregnancy. As a result, she may not experience
typical miscarriage symptoms such as bleeding or cramping, leading to the term "silent"
miscarriage. These miscarriages are usually detected during routine prenatal screenings or
ultrasound examinations.
11. Mora is reviewing the research on the various risks associated with sexual and
reproductive issues. According to the research, the risks to the health and life of the mother
from surgical abortion are significantly higher than the risks of pregnancy and giving birth.
Answer: False
Rationale:
Research generally shows that the risks associated with surgical abortion are lower than those
associated with pregnancy and childbirth. Complications from abortion procedures are rare,
especially when performed by qualified healthcare providers in a safe and regulated
environment. Conversely, pregnancy and childbirth carry inherent risks to the health and life
of the mother, including complications such as hemorrhage, infection, and hypertensive
disorders.
12. Yolanda is terminating her pregnancy through a medical abortion because this method
involves using drugs that can be taken entirely at home. She will not have to see a doctor.
Answer: False
Rationale:
While medical abortion involves the use of drugs (typically mifepristone and misoprostol) to
terminate a pregnancy, it is not entirely conducted at home without medical supervision.
Medical abortion usually requires initial assessment and counseling by a healthcare provider,
who prescribes the medications and provides instructions for their use. Additionally, followup care, including confirming the completion of the abortion and monitoring for
complications, often involves visits to a healthcare facility or communication with a
healthcare provider.
13. Abortion is not related to a higher incidence of any type of cancer.
Answer: True
Rationale:
Numerous scientific studies and medical organizations, including the American Cancer
Society and the World Health Organization, have found no causal relationship between
induced abortion and an increased risk of any type of cancer. This conclusion is supported by
extensive research conducted over several decades, which has consistently failed to establish
a link between abortion and cancer incidence.
14. A review of available research concluded that there is no scientific evidence to support the
idea that the termination of an unwanted pregnancy leads to mental health problems in
women.
Answer: True
Rationale:
Research findings regarding the association between abortion and mental health outcomes
have been mixed, but a significant body of evidence suggests that the termination of an
unwanted pregnancy does not lead to adverse mental health consequences for the majority of
women. Numerous systematic reviews and meta-analyses, which synthesize data from
multiple studies, have failed to find conclusive evidence supporting a causal link between
abortion and subsequent mental health problems.
15. The number of abortions in the United States has been increasing steadily due to easier
access to birth control.
Answer: False
Rationale:
The trend in the number of abortions in the United States is not solely attributed to access to
birth control. Multiple factors influence abortion rates, including changes in social attitudes
toward abortion, shifts in healthcare policies and regulations, availability of reproductive
healthcare services, economic factors, and demographic trends. While access to effective
contraception can contribute to reducing unintended pregnancies and abortions, it is only one
aspect of a complex set of factors affecting abortion rates.
16. When the baby’s head is said to “crown,” this means it is visible at the vaginal opening.
Answer: True
Rationale:
"Crowning" refers to the stage of childbirth when the widest part of the baby's head becomes
visible at the vaginal opening during labor. This typically occurs during the second stage of
labor, just before the baby is born. Crowning marks a significant milestone in the birthing
process, indicating that the baby is moving through the birth canal and nearing delivery.
17. In response to the demand for more personalized, parent-controlled childbirth,
freestanding birthing centers are growing in number and popularity.
Answer: True
Rationale:
Freestanding birthing centers, which offer alternative settings for childbirth outside of
traditional hospital maternity wards, have grown in number and popularity in response to the
demand for more personalized, family-centered maternity care. These centers often provide a
homelike environment, emphasizing natural childbirth practices, comfort measures, and
parental involvement in decision-making. Freestanding birthing centers may appeal to
individuals seeking a less medicalized approach to childbirth and greater autonomy in their
birth experiences.
18. Lamaze, who developed the childbirth preparedness method, took a stand against pain
medication and believed in “all-natural” childbirth.
Answer: False
Rationale:
Lamaze, a French obstetrician, did not take a stand against pain medication or advocate for
"all-natural" childbirth exclusively. Lamaze is best known for developing a childbirth
education method aimed at preparing expectant mothers for childbirth through relaxation
techniques, breathing exercises, and psychological conditioning. While Lamaze emphasized
the importance of natural coping mechanisms and reducing unnecessary medical
interventions during childbirth, he did not categorically oppose the use of pain medication or
medical interventions when warranted.
19. In the U.S. and many other industrialized nations, the number of C-section births has been
steadily rising, but the number of natural childbirth complications has not.
Answer: True
Rationale:
The rate of cesarean section (C-section) births has increased in the United States and many
other industrialized nations over recent decades, influenced by factors such as changes in
obstetric practices, maternal age, medical indications, and patient preferences. However, the
overall incidence of complications associated with natural childbirth (vaginal delivery) has
not necessarily increased in tandem with the rising C-section rate. Complications of natural
childbirth can vary depending on numerous factors, including maternal health, prenatal care,
labor management, and the presence of medical risk factors.
20. Anne is weighing the risks of having a C-section with the risks associated with a vaginal
birth. The risks of a C-section delivery for a normal birth are greater than those of a vaginal
delivery.
Answer: True
Rationale:
While cesarean section (C-section) deliveries can
21. Overall, the risks of vaginal delivery are greater than those of a C-section.
Answer: False
Rationale:
While both vaginal delivery and cesarean section (C-section) carry risks, the comparative
risks vary depending on individual circumstances, medical indications, and other factors. In
general, vaginal delivery is associated with lower risks of certain complications such as
infection, blood loss, and surgical complications compared to C-section. However, vaginal
delivery also carries risks such as perineal tearing and pelvic floor dysfunction. C-sections
may be associated with risks such as surgical complications, increased recovery time, and
potential complications in future pregnancies. The decision between vaginal delivery and Csection should be made based on individual medical considerations and preferences, and
neither method can be universally considered "safer" overall.
22. Although the chances of pregnancy during lactation (breastfeeding) may be reduced, it is
far from a sure method of contraception.
Answer: True
Rationale:
While lactational amenorrhea (absence of menstruation due to breastfeeding) can suppress
ovulation and reduce the likelihood of pregnancy, it is not a foolproof method of
contraception. The effectiveness of breastfeeding as a contraceptive method depends on
several factors, including the frequency and intensity of breastfeeding, the age of the infant,
and the mother's individual physiology. Lactational amenorrhea method (LAM) is most
effective when specific criteria are met, including exclusive breastfeeding, frequent
breastfeeding day and night, and no return of menstrual periods. However, there is still a risk
of ovulation and pregnancy, particularly as breastfeeding patterns change over time.
23. Bonnie is now 42 years old and feels it is hopeless to try to get pregnant now. Although
increasing age is associated with decreasing fertility, approximately 45% of women over 40
who wish to become pregnant eventually do so.
Answer: True
Rationale:
While fertility declines with age, especially after age 35, it is still possible for women in their
40s to conceive and carry a pregnancy to term. Although the chances of conceiving naturally
decrease with advancing age due to factors such as decreased ovarian reserve and egg quality,
many women over 40 are able to achieve pregnancy with medical assistance such as assisted
reproductive technologies (ART) or fertility treatments. Approximately 45% of women over
40 who actively seek pregnancy eventually succeed, highlighting the possibility of
conception even in later reproductive years.
24. A man’s age significantly affects fertility.
Answer: False
Rationale:
While advanced paternal age can have some impact on fertility and reproductive outcomes, it
generally has less pronounced effects compared to maternal age. Advanced maternal age is a
well-established factor associated with decreased fertility, increased risk of miscarriage, and
higher rates of chromosomal abnormalities in offspring. However, research on the effects of
paternal age on fertility and pregnancy outcomes is less consistent. Advanced paternal age
may be associated with slightly decreased sperm quality and increased risk of certain genetic
conditions in offspring, but the effects are generally less significant compared to maternal
age-related decline in fertility.
25. For optimum fertility, a man should abstain from ejaculation and “save up” his semen for
a few days to increase the number of sperm cells in his ejaculate.
Answer: False
Rationale:
Contrary to the popular misconception that abstaining from ejaculation increases sperm count
and fertility, regular ejaculation is actually beneficial for sperm health and fertility. Frequent
ejaculation helps to maintain sperm quality by preventing the accumulation of old, damaged
sperm cells in the reproductive tract and promoting the production of fresh, motile sperm.
Extended periods of abstinence can lead to decreased sperm motility and viability, potentially
reducing fertility. Therefore, for optimum fertility, men are advised to engage in regular
sexual activity or ejaculation, rather than prolonged periods of abstinence.
26. Both frequency of intercourse and timing of intercourse can impact fertility.
Answer: True
Rationale:
Both the frequency and timing of intercourse can influence fertility by optimizing the chances
of conception. Frequent intercourse, especially during the woman's fertile window (the days
leading up to and including ovulation), increases the likelihood of sperm reaching and
fertilizing the egg. Timing intercourse to coincide with ovulation, when the woman is most
fertile, maximizes the chances of conception. Various methods, such as tracking menstrual
cycles, monitoring basal body temperature, and using ovulation predictor kits, can help
couples identify the most fertile days for intercourse.
27. Fertility drugs such as clomiphene citrate have been designed to stimulate ovulation in
women.
Answer: True
Rationale:
Fertility drugs such as clomiphene citrate (Clomid) are commonly used to induce ovulation in
women with ovulatory disorders or irregular menstrual cycles. Clomiphene citrate works by
blocking estrogen receptors in the hypothalamus, leading to increased secretion of folliclestimulating hormone (FSH) and luteinizing hormone (LH). This hormonal stimulation
promotes the growth and maturation of ovarian follicles, ultimately triggering ovulation.
Fertility drugs like clomiphene citrate are often prescribed as a first-line treatment for
ovulatory disorders and are commonly used in conjunction with timed intercourse or assisted
reproductive technologies (ART) such as intrauterine insemination (IUI).
28. Most health insurance covers ART.
Answer: False
Rationale:
While some health insurance plans may provide partial coverage or reimbursement for certain
aspects of assisted reproductive technologies (ART), such as diagnostic testing or
consultation fees, coverage for ART procedures themselves (such as in vitro fertilization, or
IVF) varies widely and is often limited or excluded from standard health insurance plans.
ART procedures can be expensive, involving multiple medical visits, diagnostic tests,
medications, and invasive interventions, making them financially burdensome for many
individuals or couples. Some insurance plans offer separate fertility treatment coverage as an
optional add-on or require patients to purchase specialized fertility coverage for additional
costs.
29. Rachel’s fallopian tubes are blocked. Her doctor suggests she consider IVF because this
procedure is typically used when a woman’s fallopian tubes are blocked or missing.
Answer: True
Rationale:
In vitro fertilization (IVF) is a common treatment option for infertility caused by tubal
factors, such as blocked or damaged fallopian tubes. IVF involves retrieving eggs from the
woman's ovaries, fertilizing them with sperm in a laboratory setting, and transferring the
resulting embryos into the woman's uterus for implantation. By bypassing the fallopian tubes,
IVF enables fertilization to occur outside the body, making it an effective treatment
30. ZIFT combines IVF and GIFT.
Answer: True
Rationale:
ZIFT, or Zygote Intrafallopian Transfer, indeed combines elements of both IVF (In Vitro
Fertilization) and GIFT (Gamete Intrafallopian Transfer). In ZIFT, fertilization of the egg by
sperm occurs outside the woman's body, similar to IVF. However, unlike IVF where the
fertilized embryos are transferred into the uterus, in ZIFT, the fertilized eggs (zygotes) are
transferred directly into the fallopian tubes. This method allows the zygotes to travel
naturally into the uterus for implantation. Thus, ZIFT combines aspects of both IVF and GIFT
procedures, making the statement true.
SHORT ANSWER
1. In the ________, the pituitary gland at the base of the brain begins to secrete FSH that
enhances the follicle growth and ovum development.
Answer: follicular phase
Rationale:
The follicular phase is the first phase of the menstrual cycle during which the pituitary gland
releases follicle-stimulating hormone (FSH), which stimulates the growth and development
of follicles in the ovaries, leading to ovum maturation.
2. Fertilization usually takes place in the upper region of the ________.
Answer: fallopian tube
Rationale:
The fallopian tubes are the structures through which the mature egg travels from the ovary to
the uterus. Fertilization typically occurs in the upper third of the fallopian tube after sexual
intercourse.
3. The ovum is capable of being fertilized for only ________.
Answer: 12-18 hours
Rationale:
After ovulation, the egg (ovum) is viable for fertilization for about 12 to 18 hours. If
fertilization does not occur within this time frame, the egg will disintegrate.
4. Pregnancy is a two-stage process: ________ and ________.
Answer: conception; implantation
Rationale:
Pregnancy begins with conception, which is the fusion of sperm and egg to form a zygote.
Following conception, the zygote implants itself into the lining of the uterus in a process
called implantation, initiating pregnancy.
5. ________occurs when a fertilized egg implants somewhere in the woman’s body other
than the uterus, most often in one of the fallopian tubes.
Answer: Ectopic pregnancy
Rationale:
An ectopic pregnancy occurs when a fertilized egg implants outside of the uterus, commonly
in one of the fallopian tubes. This condition is dangerous and requires medical intervention.
6. Preterm birth, also known as ________, is the birth of a fetus well before the nine-month
pregnancy period is complete.
Answer: premature birth
Rationale:
Preterm birth, or premature birth, refers to the delivery of a baby before completing the full
37 to 40 weeks of gestation. This can lead to various health complications for the newborn.
7. Nearly ________ percent of all surgical abortions in the United States occur within the first
trimester of pregnancy.
Answer: ninety
Rationale:
Approximately 90% of surgical abortions in the United States are performed within the first
trimester of pregnancy, typically before the 12th week.
8. ________ is a method of abortion used early in the pregnancy in which a small tube is
inserted through the cervix to extract the contents of the uterus.
Answer: Vacuum aspiration
Rationale:
Vacuum aspiration, also known as suction aspiration, is a common method of abortion used in
the first trimester. It involves the insertion of a small tube through the cervix into the uterus to
remove the contents, including the embryo or fetus.
9. A ________ is usually a woman who has been trained in most aspects of pregnancy, labor,
and delivery but is not a physician or registered nurse.
Answer: midwife
Rationale:
A midwife is a healthcare professional, typically a woman, who is trained to provide care
during pregnancy, childbirth, and the postpartum period. While midwives are highly skilled in
managing normal pregnancies and deliveries, they are not usually physicians or registered
nurses.
10. The __________ is currently the most popular regional anesthesia method, in which pain
relieving medication is delivered “as needed” through a small tube inserted near the base of
the spine.
Answer: epidural
Rationale:
An epidural is a form of regional anesthesia commonly used during childbirth to provide pain
relief. It involves the insertion of a catheter into the epidural space near the spinal cord,
through which pain-relieving medication can be administered continuously or as needed.
11. A severe form of postpartum depression called ________ may be characterized by
delusions, hallucinations, and extreme mental disorganization, leading to extreme, and often
violent, behaviors.
Answer: postpartum psychosis
Rationale:
Postpartum psychosis is a rare but severe mental health condition that can occur after
childbirth. It is characterized by symptoms such as delusions, hallucinations, extreme mood
swings, and confusion, often leading to dangerous behaviors.
12. Donna and Dave would qualify as a couple experiencing ________ because of their lack
of conception over 12 consecutive months of regular unprotected sex.
Answer: infertility
Rationale:
Infertility is defined as the inability to conceive after 12 months of regular unprotected sexual
intercourse. Donna and Dave's situation fits this definition, indicating a potential fertility
issue.
13. Damaged or blocked fallopian tubes are most commonly the result of ________ or
________.
Answer: pelvic inflammatory disease; endometriosis
Rationale:
Pelvic inflammatory disease (PID) and endometriosis are two common causes of damage or
blockage in the fallopian tubes. PID is often caused by sexually transmitted infections, while
endometriosis involves the growth of endometrial tissue outside the uterus, which can affect
the fallopian tubes.
14. ________ is the technique commonly known as the one that produces “test tube babies.”
Answer: In vitro fertilization
Rationale:
In vitro fertilization (IVF) is a reproductive technology commonly known as the process of
creating "test tube babies." It involves fertilizing an egg with sperm outside the body in a
laboratory dish, followed by the transfer of the resulting embryo(s) into the uterus.
15. __________ was developed to assist a couple when the man’s sperm production is either
very low, the cells have poor shape or mobility, or some other problem exists with his sperm
or semen that makes other ART methods ineffective.
Answer: ICSI
Rationale:
Intracytoplasmic sperm injection (ICSI) is a specialized form of in vitro fertilization (IVF)
used to treat male infertility issues. It involves the injection of a single sperm directly into the
egg to facilitate fertilization when sperm quality or quantity is a concern.
ESSAY
1. Describe the journey of the sperm and egg from ejaculation and ovulation to conception,
and then discuss the events that occur from conception to implantation.
Sample response:
The egg that was released from the ovary is drawn up into the fallopian tube. One sperm cell
from the ejaculate must meet and penetrate the egg. Once conception has taken place, this
new organism is called a zygote. Over the course of two to four days, it divides and moves
down the fallopian tube to the uterus. By the time it arrives in the uterus, it consists of about
90 cells. It is now called a blastocyst. On the sixth or seventh day after fertilization, it
implants in the wall of the uterus. The successful attachment is the beginning of pregnancy.
Once implantation occurs, the blastocyst is referred to as an embryo.
2. Discuss the fetal development through the three trimesters of pregnancy.
Sample response:
First trimester
• Month 1. The embryo resembles a tadpole or tiny shrimp; the buds of arms and legs begin
to appear; the heart begins to beat; the embryo is about the size of the eraser on a pencil and
weighs less than 1 ounce.
• Month 2. The embryo grows to about 1 inch long; distinct fingers and toes appear; the heart
muscle has divided into chambers; facial features are visible; the placenta is functioning,
bringing nutrients to the embryo and carrying wastes away; the embryo takes on a more
human appearance.
• Month 3. The embryo, now called a fetus, grows to about 3 inches in length; fingers and
toes have nails; the fetus begins to move in the uterus, but movements cannot usually be felt
by the mother; all vital organs and muscles are formed and functioning by the tenth week.
The fetus now weighs about 1.2 ounces (the equivalent of a dozen U.S. pennies).
Second trimester
• Month 4. Fetal movement increases and includes kicking, sucking, and swallowing; about
20 tooth buds develop; fingers and toes are more clearly defined; the sex of the fetus may
now be determined by observing the growth of the genitals with ultrasound. The fetus grows
to 6 or 7 inches long and now weighs around 6 or 7 ounces.
• Month 5. Fetal activity increases further and may even include rolls, flips, and somersaults;
the fetus enters a predictable waking–sleeping cycle; the mother will feel frequent
unmistakable movements of the fetus; fetal eyelashes and eyelids appear; growth accelerates
to 8 to 10 inches long: and weight increases to nearly a pound by the end of the fifth month.
• Month 6. Fetal skin is red and wrinkled and covered with a protective coating called the
vernix; the eyes open and close; the fetus’s lungs are “breathing” the amniotic fluid in and
out; the fetus is capable of hearing sounds from the outside world; rapid growth continues as
the fetus reaches 11 to 14 inches in length and 1.5 to 2 pounds. If born in this month, the
baby, though very premature, will have a good chance of survival with specialized intensive
care.
Third trimester
• Month 7. The fetus’s taste buds have developed, and it may be observed sucking its thumb;
muscle tone develops through kicking and stretching; clear responses to external sounds may
be observed; layers of fat are forming beneath the skin; internal organs are maturing quickly.
If born prematurely at this time, the baby has a high chance of survival and a normal life with
proper medical care. The fetus reaches 14 to 16 inches long and about 3 pounds by the end of
the seventh month.
• Month 8. The fetus rotates to head-down position; the brain grows quickly; overall growth
is now at a rate of a half pound per week; the fetus’s kicks and elbow thrusts now become
visible from the outside surface of the mother’s abdomen; the fetus’s internal organs, except
for the lungs, are nearly fully developed; the skull bones are flexible and not yet connected to
allow them to compress for passage through the birth canal; size is approximately 18 inches
long, and weight is 4 to 6 pounds at the end of this month.
• Month 9. The fetal lungs develop fully and are ready to breathe air; the skin typically
becomes pink and smooth; the fetus now turns and settles head down, low in the mother’s
uterus, in preparation for birth; activity decreases, producing fewer noticeable movements; on
average the fetus reaches 18 to 22 inches in length and 6 to 9 pounds as the onset of labor
approaches.
3. What are the stages of labor and how do they progress?
Sample response:
At the onset of labor, called stage one labor, contractions begin as the cells of the uterus, now
the largest muscle in the mother’s body, contract in sequence along its length, pulling and
straightening the uterus and pushing the fetus down toward the cervix. At this point, the
cervical canal is beginning to dilate (become larger in diameter) and efface (become thinner).
During the beginning of stage one labor, the cervix is about 1 to 2 inches dilated and as stage
one labor continues it will continue to dilate to approximately 10 centimeters or about 4
inches.
Stage two labor leads to the birth of the baby. Contractions begin to involve the muscles of
the abdomen as well as the uterus itself. The mother has somewhat more control over these
contractions, and many women report that this sense of control seems to reduce the amount of
pain they perceive. At this point, the woman will feel a great deal of abdominal pressure as
her body is working to deliver her baby.
In stage three labor, within a few minutes following the completed birth of the infant, the
placenta (which has joined the fetus and mother throughout pregnancy) is expelled from the
uterus with the umbilical cord attached.
4. Describe the status of C-sections today, and discuss possible reasons why there are so
many C-sections.
Sample response:
In the United States and many other industrialized countries, the number of C-section births
has been steadily rising over the past ten years or so, but the number of natural childbirth
complications has not. In 2009, the U.S. cesarean birth rate reached its highest point in
history, accounting for 33 percent of all births, which represents a 60 percent increase since
1996. Nearly one quarter of C-sections are not medically necessary, but are voluntarily
chosen by the pregnant women. Why so many C-sections? Various possible reasons are
discussed in the birthing literature: (1) More mothers are choosing to have C-sections, (2)
doctors are more willing to recommend them due to fears of malpractice litigation if any
problems arise from a potentially complicated vaginal birth, (3) the average age at which
women give birth has risen significantly, increasing the possibility for complications that may
lead to cesarean births, and (4) C-section births are approximately twice a profitable for the
hospital than uncomplicated vaginal births.
5. Discuss infertility, including the causes, testing, and treatment options. Describe the
fertility testing a couple might encounter if they were experiencing infertility.
Infertility, sometimes called “impaired fertility,” is typically defined as the lack of conception
by a heterosexual couple after 12 consecutive months of trying to become pregnant; that is,
having regular, unprotected intercourse. In the United States, the number of couples who
meet this definition of infertility is estimated to approximately 10 percent, which works out to
approximately 5 million couples.
Causes. Research has shown that the main causes of infertility break down as follows: 25
percent due to a male sperm factor (e.g., low number, poor quality, or low motility), 20
percent due to a female ovarian problem (e.g., no ovulation or poor quality ova), 14 percent
due to a female tubal problem (e.g., fallopian tube blockage), and 41 percent due to other
problems, or there is no identifiable problem in either partner (unexplained infertility).
Testing. The main test for the male is a semen analysis, in which a sample of the man’s semen
(usually gathered through masturbation into a sterile cup) is analyzed microscopically to
check for adequate numbers, movement, and formation of the man’s sperm cells (a do-ityourself home semen analysis kit now exists). For the woman, tests may include a
hysterosalpingogram, also (thankfully) referred to as the HSG, an X-ray that allows the
doctor to view the interior of the uterus and fallopian tubes to check for malformations or
blockages. Sometimes doctors need to have a direct, internal look at the ovaries, fallopian
tubes, and uterus. This is accomplished with a laparoscopy, in which a tube with a tiny
camera and light is inserted through a very small incision in the abdomen
Treatment options. Several fertility drugs such as clomiphene citrate (brand names, Clomid
and Serophene) have been developed to stimulate ovulation in women and the drug may
assist in sperm production and quality in men (Murdock, 2004). Surgical procedures may be
effective in some cases to unblock fallopian tubes, repair testicular or related disorders, or
remove cysts or scar tissue from the uterus, ovaries, or fallopian tubes.
Intrauterine insemination, often referred to as “artificial insemination,” is a rather simple
process of inserting a small tube through the woman’s cervix and injecting sperm cells
directly into the uterus.
Four methods of ART are in current use:
• In Vitro Fertilization (IVF). This technique is probably the best known, the one said to
produce “test tube babies.” It does not involve growing a baby in a test tube, of course, but
rather a process in which ova (eggs) are extracted from the woman’s ovaries during a
laparoscopy, fertilized with sperm in a shallow dish in the lab (in vitro means “in glass”), and
then placed into her uterus through her cervix approximately three days later. Typically, three
to five zygotes are transferred to help ensure at least one pregnancy, and thus this procedure
increases the chances of multiple births.
• Gamete Intrafallopian Transfer (GIFT). This procedure is nearly the same as IVF except
that fertilization occurs naturally in the fallopian tube. As in IVF, eggs are retrieved from the
ovaries and mixed with the father’s sperm in the lab. The sperm and eggs are then transferred
to the fallopian tubes for conception using laparoscopic surgery. This method can be used
only for women who have at least one healthy fallopian tube.
• Zygote Intrafallopian Transfer (ZIFT). ZIFT combines IVF and GIFT. The process for
harvesting and fertilizing the ova is exactly the same as in IVF, but instead of transferring the
zygotes to the uterus, they are placed into the fallopian tube using the laparoscope.
• Intracytoplasmic Sperm Injection (ICSI). This ART method was developed to assist a
couple when the man’s sperm production is very low, the cells have poor shape or motility, or
some other problem exists with his sperm or semen that makes the other ART methods
ineffective. In ICSI, a single sperm cell from the man is injected using a microscopic needle,
directly into each harvested egg from the woman. The resulting zygote is then transferred
after a few days into the mother’s uterus.
