Estrogen binds to the ER receptor in the anterior pituitary, inhibiting
release of FSH. Progestin also reduces frequency of GnRH release
from the hypothalamus.
Estrogen binds to the ER receptor in the anterior pituitary, inhibiting
release of FSH. Progestin reduces frequency of LH release from the

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.
