[QUOTE="Cataceous, post: 212890, member: 38109"] Progesterone does have some ability to suppress the HPTA. Therefore sufficient exogenous administration could hurt fertility, at least in those with functioning HPTAs. [INDENT][I]Like other sex steroids, progesterone is expressed in the male as well as the female, albeit at lower levels. The precise role of progesterone in normal male physiology is unknown, but [B]progesterone receptors have been demonstrated in the male hypothalamus, pituitary, and reproductive tract[/B].[/I][/INDENT] [INDENT][I][/I][/INDENT] [INDENT][I]Progestins enhance male hormonal contraceptive efficacy when combined with androgens, an effect attributed to increased hypothalamic-pituitary suppression of gonadotropin secretion directly or through the androgen receptor.
