Estrogen binds to the ER receptor in the anterior pituitary, inhibiting release of FSH. Progestin reduces frequency of LH release from the anterior pituitary. Estrogen reduces frequency of LH release from the anterior pituitary. Progestin inhibits FSH secretion from the hypothalamus. 4/5 What is the mechanism of action of sildenafil? It is a vasodilator, increasing bloodflow to the corpus cavernosum. It is a L-type calcium channel blocker, reducing influx of calcium from smooth muscle stores. It is an alpha-1 AR agonist, dilating blood vessels to increase vascular flow to corpus cavernosum It inhibits phosphodiesterase 5, preventing conversion of cGMP to 5' GMP, lowering iCa stores, relaxing the smooth muscle. 5/5 Which of the following is NOT a side effect of the hormone oestrogen?
