I see all that. Have seen it for years - and have addressed it numerous times. But this thread was not about androgen receptors. A few thoughts: 1) First and foremost - It's not all androgen receptors. The decline occurs only in a few selected regions of the reward circuit (deep in the brain). The androgen receptors on hair follicles, vocal cord, and voice box cartilages would have to be affected. No evidence for that and no available mechanism for ejaculation to have a direct effect on all androgen receptors, everywhere in the body. 2) Deeper voice cannot be caused by either an increase in testosterone or androgen receptors because testosterone causes a deepening by thickening the vocal ligaments and enlarging the cartilages in your voicebox. This takes a long time, and would manifest as a larger voice box. Lower voices are reported in a few days to weeks. I suspect relaxing of the hyoid muscles, thus lower the position the voice box. In addition, guys report that their low voice vanishes when they relapse. 3) Increased hair is one reported benefit, but it is extremely rare. We also hear of increased hair on the head, which should involve lowered testosterone. How do you explain away opposing androgen effects? Just like I said in the FAQ you linked to - It is possible that hormones (rarely assessed or unknown) are affected by porn addiction. I'm hesitant to suggest that "high levels of ejaculation" cause long term changes in circulating hormones, because because of the many reasons cited above...and many more. However, Porn addiction could affect regions of the hypothalamus and thus hormones or brain stress systems. Pure speculation. Or porn addiction and everything associated with it (isolation, anxiety, poor relationships, etc) could alter the brains stress response, alter adrenal gland hormones - and affect many systems, including hair growth.
