Maybe what we really need is a sort of Phytotestosterone type thing - a compound which ould fool the endocrine system into believing that there is too much T of all sorts floating around. This would then shut down the production process

Hi Miranda,

Essentially that's already happening,

High serum levels of estrogen also trick the brain into thinking that enough testosterone is being produced, further slowing the natural production of testosterone. This happens when estrogen saturates testosterone receptors in the hypothalamus region of the brain. The saturated hypothalamus then stops sending out a hormone to the pituitary gland to stimulate secretion of luteinizing hormone, which the gonads require to produce testosterone. High estrogen can thus shut down the normal testicular production of testosterone



As estrogen levels increase with age, testosterone cell stimulation may be locked in the "off" position, thus reducing sexual arousal and sensation and causing the loss of libido so common in aging men.
