Erectile Function

Outcome Reproductive

Depends on nitric oxide signalling, which needs DHT and adequate estradiol. Compounds that suppress natural testosterone without providing strong androgenic signal are the classic cause of failure here.

Erectile Function stimulates

Estrogen Receptor alpha

The estrogen receptor that dominates breast tissue, liver and the pituitary feedback loop. Gynecomastia and much of the negative feedback on LH run through it.

Erectile Function suppresses

Progesterone Receptor

The progesterone receptor. 19-nor steroids are structurally close enough to progesterone to activate it, which is why nandrolone and trenbolone produce progestogenic side effects that an aromatase inhibitor cannot touch.
