6. Discuss the research on the impact of excessive drinking during pregnancy. How does alcohol affect the fetus? Which women are at risk for drinking during pregnancy? What role do cultural norms play in the tendency to use alcohol when pregnant?
Alcohol crosses the placenta, inhibiting normal neural growth and producing potential learning and behavior problems. Specifically, children born to alcoholic mothers may have a condition called Fetal Alcohol Syndrome (FAS), characterized by small birth weights, impaired brain development, facial abnormalities, and serious developmental disorders. These children may also have a less severe set of conditions called Fetal Alcohol Spectrum Disorders. Binge drinking or having several drinks throughout pregnancy puts children at highest risk, although the odds vary depending on the resilience of the mother and fetus. Most women stop drinking after learning they are pregnant, or cut down their intake dramatically. Those who continue tend to be anxious or depressed. Ironically though, in one study in the Netherlands, well-educated women were most likely to continue to drink (but only socially) when pregnant. In general, Europeans are more lax than U.S. women about urging total abstinence from alcohol during pregnancy, as in European nations, having a glass or two of wine with meals is a "normal" cultural practice.

10. Define Assisted Reproductive Technologies (ART), discuss its variations, and explore the concerns, issues, and problems facing couples who choose to undergo these procedures.
Assisted reproductive technologies (ART) refer to any procedure in which fertilization occurs outside of the womb. Today, there are many variations of ART. Doctors may inject the partner's sperm directly into the egg (if the issue is male fertility problems); the woman may use a donor egg or rely on a sperm bank to conceive. If she cannot undergo a full pregnancy, the woman's fertilized egg may be inserted into "a carrier womb" (another woman) to carry the baby to term. If a third party is involved, ART can produce emotional complications. But the main issue for couples considering ART is that this procedure is costly, time consuming, and success rates—especially at older maternal ages—are low. ART babies have a slightly higher risk of birth defects. Also, couples may have to undergo a distressing procedure called "fetal reduction" if too many inserted embryos "take" since there is a higher risk of miscarriage with multiple births. Still, Assisted reproductive technologies (ART) can offer an incredible gift to couples who would not otherwise able to have their own biological child.

Assisted reproductive technology; ART

11. Give a brief account of the history of birth in the developed world.
Before the twentieth century, birth was dangerous. Physicians knew next to nothing about the female anatomy, their interventions carried the risk of infection (making childbirth more dangerous), and women shunned hospitals because they were full of disease. Then, during the early twentieth century, the field of medicine advanced, maternal mortality plummeted, and birth in a hospital became the norm. In the 1960s, women began to protest the medicalization of birth, and the natural childbirth movement took off. Today, affluent women have many options along a continuum from natural to medical when they give birth.

9. Xenia carries the gene for hemophilia and asks a doctor for information about her risks should she decide to have children. What should the doctor let Xenia know?
Hemophilia is a sex-linked illness, so Xena's sons will have a fifty-fifty (or 50 percent) chance of having hemophilia, while her daughters will have a fifty-fifty (or 50 percent) chance of being carriers for the disease. The good news is that while in the past, hemophilia was often fatal at a young age, now it can be controlled by blood transfusions.

Social policy birth issues in the developed world: high rates of cesarean sections (C-sections) and clear socioeconomic differences in infant mortality in every affluent nation. For instance, poor women are at higher risk of giving birth to premature babies. The main birth issue in the developing world: unacceptable lack of access to decent prenatal care and routine obstetrical interventions, such as C-sections, in the world's most impoverished nations.
8. A couple, both carriers of the cystic fibrosis gene, visit a genetic counselor for advice. What should the counselor say?
The counselor should tell the couple that each child they conceive will have a 1 in 4 chance of getting cystic fibrosis (CF). Cystic fibrosis (CF) is still an incredibly life-shortening disease, but today some people can live to their thirties with this illness. The counselor also should tell them to be prepared for repeated hospitalizations. They and other family members will experience much stress. There are tests they can take during the first trimester or second trimesters of pregnancy to find out if a fetus will have the illness. The counselor should let the couple know that their decision to have a test and to go forward with any pregnancy is up to them.
7. Discuss the teratogenic impact of stress during pregnancy. What specific effects might stress have on the fetus? Which are the main considerations, issues, and findings in this area?
When pregnant women undergo excessive levels of stress, the main risk is going into labor early. Stress hormones transmitted to the fetus via the amniotic fluid might also cause a newborn to be excessively jumpy during the first months of life. Although the research on the impact of pregnancy stress on the fetus is confusing, the timing and intensity of the stressors seem to make a difference. For instance: Is the person experiencing an overload of problems or an unwanted pregnancy? Did the stressful events occur in late pregnancy or immediately before conception? Most important, how does the woman cope with stress? Does she take steps to positively confront her problems or does she bury her anxieties and act out through self-destructive behaviors such as smoking or excessive alcohol use?
