Envision yourself as a physician whose patients sometimes ask about birth control. Provide a contraceptive method for each of the following patients, and explain why it would be appropriate: couple A, a man and woman who have intercourse regularly but never want to have children; couple B, a man and woman who have intercourse regularly and want to have children someday; and person C, a single woman who occasionally has intercourse with single men and does not wish to become pregnant. Be sure to include the level of protection against STDs that each person is likely to need.
Which of the following statements about the Female Reproductive System is TRUE?
Select one:
A) Follicles are located in the ovarian cortex, which has a rich supply of blood vessels and nerve fibres.
B) The female gonads secrete progesterone, estrogen, and oxytocin.
C) Connective tissue makes up the walls of the ovaries, uterus, and vagi na – whereas epithelial tissue lines the inner sides of the uterus, Fallopian tubes, and vagina.
D) Microbial growth is deterred by the non-acidic environment of the vagi na.
E) Each ovary is held in place within the abdominopelvic cavity by three ligaments – the broad, suspensory, and uterine ligaments.
Some couples practice natural family planning (also known as the rhythm method of birth control), which involves abstaining from sexual intercourse during the time that a woman can become pregnant in her menstrual cycle. The egg only survives in the Fallopian tube for 24 hours after ovulation, so conception can only happen during a 24-hour period each month. However, this form of contraception is very unreliable and is not recommended for couples who are actively trying to avoid pregnancy.
Which of the following is NOT a reason why this form of birth control is unreliable?
Select one:
a. Women always ovulate on the same day of their menstrual cycle every month.
b. Ovulation can be affected by stress or illness.
c. Sperm can survive in the Fallopian tubes for 3 to 5 days.
d. It is difficult to predict exactly when in her cycle a woman ovulates.

- Would ISCI be an option? Why or why not? Jan, a 32-year-old woman, and her husband, Darryl, have been married for 7 years. They have attempted to have a baby on several occasions. Five years ago, they had a first-trimester miscarriage, followed by an ectopic pregnancy later the same year. Jan continued to see her OB/GYN physician for infertility problems but was very dissatisfied with the response. After four miscarriages, she went to see a fertility specialist, who diagnosed her with severe endometriosis and polycystic ovarian disease (detected by hormone studies). The infertility physician explained that these two conditions were hampering her ability to become pregnant and thus making her infertile. She referred Jan to a genetic counselor. At the appointment, the counselor explained to Jan that one form of endometriosis (MIM 131200) can be a genetic disorder, and that polycystic ovarian disease can also be a genetic disorder (MIM 184700) and is one of the most common reproductive disorders among women. The counselor recommended that a detailed family history of both Jan and Darryl would help establish whether Jans problems have a genetic component and whether any of her potential daughters would be at risk for one or both of these disorders. In the meantime, Jan is taking hormones, and she and Darryl are considering alternative modes of reproduction. Using the information in Figure 16.4, explain the reproductive options that are open to Jan and Darryl.arrow_forwardIn the fertility awareness method of birth control, a woman gauges her monthly fertile period by monitoring changes in the consistency of her vaginal mucus.
