Step by step
Solved in 2 steps
- Which of the following statements accurately describes the pathogenesis of polycystic ovarian syndrome? Question 28 options: a) Excessive androgens that affect follicular decline by suppressing apoptosis, enabling follicles, which normally disintegrate to survive b) A decrease in leptin levels that reduces the hypothalamic pulsatility of GnRH, which reduces the number of follicles that mature c) A disorder of the anterior pituitary that increases the release of FSH, which reduces the release of LH d) Testosterone that stimulates androgen secretion by the ovarian stroma and reduces SHBG indirectlyWhy does the patient have light menstrual periods that have now stopped? Choose all the INCORRECT answer(s) from the options below a) There would be no development of follicles during the follicular phase of the ovarian cycle b) The endometrial lining will continue to increase in thickness c) The cells that produce FSH and LH are located in the hypothalamus and not in the pituitary gland. d) The levels of oestrogen would be higher than normal during the follicular phase of the ovarian cycle. e) The tumor would only affect the cells the produce the hormone that stimulates milk secretion.Gross Anatomy of the Human Male Reproductive System a) List the two main functions of the testis. b) Why are the testes located in the scrotum rather than inside the ventral body cavity? c) An enlarged prostate is associated with a number of disorders, including prostatitis and prostate cancer.

Development of the corpus luteume). GnRH pulse frequency to peakSelect the FALSE statement/s: A) The functional layer of the endometrium sloughs off when estrogen levels are at their lowest but progesterone levels at their highest. 1 OB) Every month, the 20 secondary follicles release 20 ova. OC) XX genotypic female exposed to high levels of androgen in utero will develop male-like exfernal genitalia OD) Both A and B OE) Both B and CA 20-year-old woman with a history of irregular cycles complains of recent amenorrhea.
