Based on the schematic below, illustrating the control of the hypothalamus and the pituitary gland by the ovarian hormones, how would you design a hormonal female contraceptive that keeps secretion of FSH and LH low in order to prevent ovulation?
What’s a good solution or helping that could help birth control?
Why do we consider a growing child to be alive, but not a growing crystal? Is abortion the taking of a human life? If so, what about a contraceptive foam that kills only sperm?

Unfortunately, the previous summer scholarship student wasn’t as competent as you and accidentally mixed up the histological slides of an ovary from a 6-year-old girl and a 25-year-old woman. The lead researcher has asked you to separate and correctly label the slides. Thinking about folliculogenesis throughout the lifetime of a person with ovaries, what microscopic feature(s) (other than size) can you use to distinguish the ovaries of a 6-year-old girl and a 25-year-old woman and why?arrow_forwardWith all the sex that occurs in the media, why doesn’t anybody on the soaps or in movies get an STI? (Similarly, hardly anyone gets pregnant unless it’s a made-for-TV movie on the subject.) What messages do they convey about STIs and risk taking? Feel free to reference specific shows/movies. Who should be responsible for safe sex? Should women take a more active role given that most contraceptive methods are made for women? What can men do to encourage safe sex?

- Figure 18.17 Which of the following statements about hormone regulation of the female reproductive cycle is false? a. LH and FSH are produced in the pituitary, and estrogen and progesterone are produced in the ovaries. b. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. c. Both progesterone and estrogen are produced by the follicles. d. Secretion of GnRH by the hypothalamus is inhibited by low levels of estrogen but stimulated by high levels of estrogen.arrow_forwardFigure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles.

Mllerian duct system to degenerate d. indifferent gonad to become an ovary e. indifferent gonad to become a testisarrow_forwardShould fertility clinics be required to disclose all the risks of ART to couples seeking fertility treatments? Are state and/or federal laws the best way to achieve this?arrow_forwardSome couple 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 from 24 hours after ovulation, so conception can only happen during a 24-hour period each month. However, this form of contraceptive 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? A. Sperm can survive in the fallopian tubes for 3 to 5 days. B. Ovulation can be affected by stress or illness. C. Women always ovulate on the same day of their menstrual cycle every month. D. It is difficult to predict exactly when in her cycle a woman ovulates.arrow_forward
