- 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.Figure 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. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.Besides producing gametes (sperm and eggs), the primary male and female reproductive organs also produce sex hormones. The _____ and the pituitary gland control secretion of both.
- Match each hormone with its effect. oxytocin a. growth of facial hair testosterone b. uterus contracts LH c. LH, FSH are released GnRH d. surge causes ovulation FSH e. follicle develops HCG f. milk is produced prolactin g. corpus luteum is maintainedAlthough the most effective form of an oral contraceptive for woman contain estrogen and progestin, some birth control pills contain a small dose of progestin-only. This is because there are many risks and side effects. Which of the following statements is NOT a reason for using a progestin-only oral contraceptive? Select one: A. progesterone maintains the corpus luteum as corpus luteum release a large amount of progesterone and estrogen. B. progesterone suppresses the maturation of follicles, thereby preventing ovulation of a mature ovum. C. progestin-only oral contraceptives prevent the production of FSH and LH in the anterior pituitary. D. progesterone suppresses the production of GnRH in the hypothalamus.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?
- Which of the following is/are true with regards to hormones in the reproductive tract? Estrogen secretion is stimulated exclusively by LH. Progesterone is secreted by ovarian follicles & the corpus luteum. Progesterone secretion is stimulated exclusively by FSH. Estrogen is secreted by ovarian follicles & the corpus luteum. All of the aboveWhich of the following is/are true with regards hormones in the reproductive tract? * All the choices Progesterone is secreted by ovarian follicles & the corpus luteum. Estrogen secretion is stimulated exclusively by LH. Progesterone secretion is stimulated exclusively by FSH. Estrogen is secreted by ovarian follicles & the corpus luteum.Although the most effective forms of oral contraceptive for women contain estrogen and progestin, some birth control pills contain a small dose of progestin only. This is because there are many risks and side effects associated with estrogen.Which of the following statements is NOT a reason for using a progestin-only oral contraceptive? Select one: a. Progesterone suppresses the maturation of follicles, thereby preventing ovulation of a mature ovum. b. Progesterone maintains the corpus luteum as corpus luteum releases a large amount of progesterone and some estrogen. c. Progestin-only oral contraceptives prevent the production of FSH and LH in the anterior pituitary. d. Progesterone suppresses the production of GnRH in the hypothalamus.
- After learning about the reproductive systems, how would advise a couple with following concern: "If we do not want a baby for next two years, how can we calculate the safe sex period?" She shares that her cycle is regular but not standard 28 days long cycle (so the standard explanation form different sources won't work unless you think critically)! At what time of the female cycle is she most likely to prevent fertilization of her ovulated egg? Consider the fact that her cycle is not 28 days but longer or shorter (you pick). Do males have any time (in their cycle- if any) when their gametes would not be able to fertilize the egg? In other words when can intercourse lead to least chance of pregnancy? Feel free to check with your older friends, doctors, nurses, or anyone who you feel comfortable talking about this.The sex response is an inborn reflex. What stimuli trigger the reflex? What two physiological mechanisms (other than the brain) are responsible for the physical changes that appear during the sexual response? [Hint: One begins with “va” and the other with “my.”] Give examples of the effects of both these two physiological mechanisms.Which of the following statement does NOT describe the role of progesterone in the female reproductive system? Select one: A. Prevent the shedding of the endometrium B. Ensures that the endometrium is thick enough to support a fertilized egg C. Trigger the thickening of the endometrium D. Prevent smooth muscle construction, thereby preventing premature birth
