Women with inadequate secretion of GnRH are often treated for their infertility with drugs that mimic the action of this hormone. Can you suggest a possible reason that such treatment is often associated with multiple births?
Hight levels of progesterone promote:a). Development of the follicle b). Re-growth of the endometrium and mensesc). Thickening, vascularization and glandularization of the endometrium d). Development of the corpus luteume). GnRH pulse frequency to peak
Clomiphene Citrate is a fertility drug that stimulates hypothalamic secretion of Gonadotropin releasing Hormone (GnRH) in females and induces ovulation. Explain how increased GnRH with Clomiphene Citrate treatment would affect follicle maturation and ovulation in women (explain how increased GnRH would affect FSH, LH, Estrogen, and ovulation).

- Which of the following is NOT TRUE? A) Menopause is marked by elevated levels of gonadotropins. A spermatozoon can survive for more than five days in a female reproductive tract. C) The proliferative endometrial phase is promoted by progesterone. Synthetic estrogens act as contraceptives by preventing the ovarian luteal phase. The hormonal basis of stress-induced amenorrhea is due to the influence of the limbic system on GNRH secretion.arrow_forwardName the process of surgical removal of gonads.arrow_forwardUnlike male gonadotropins, female gonadotropins are able to promote the development of a single optimal dominant follicle during most cycles with the release of a single gamete from an LH surge and then optimization of the uterine environment for implantation. To understand pathologies in this complex system, one must understand the ideal steps within the normal menstrual cycle. Which of the following statements best describes the role of FSH in menstruation? O FSH induces granulosa cell LH receptors within the dominant follicle. O FSH stimulates follicular growth only in the early preantral stage. ( ) FSH stimulates granulosa cell androgen production. O FSH increases its own receptor numbers on theca cells. O FSH induces theca cell aromatase.arrow_forward
