I’m not saying this is true for all of PFS sufferers… Though I know myself am suffering from low testosterone and relatively high estrogen.
Estrogen: Side Effects
That said, we males only need small and youthful amounts of estrogen for optimum health. The overabundance of estrogen in middle and old age is simply a bad dream. Here are just a few of the nasty things estrogen can do to us:
Decrease testosterone production. (It binds to testosterone receptors in the brain that signal for the body to produce more testosterone.)
When estrogen binds to an androgen receptor it does not activate that receptor. Testosterone, of course, activates testosterone receptors so they do what they are supposed to do. Estrogen leaves them inert and lifeless.
Displaces testosterone in androgen receptors throughout the body. Your free testosterone is basically “all dressed up with nowhere to go”.
Perhaps worst of all, high estrogen levels causes your body to make fewer and fewer androgen receptors. This is bad, very bad.
In males, increased estrogen is associated with increased blood clotting, narrowing of the arteries and heart disease.
It increases SHBG, the protein that binds to testosterone. This decreases free, “bioavailable” testosterone that is usuable by the body. NOTE: You should also read my section on Free Testosterone. Losing Free Testosterone is a very serious issue for us males.
The erectile muscles at the base of the penis are packed with testosterone receptors. As testosterone decreases and estrogen displaces testosterone, these muscles slowly atrophy leading to erectile difficulties.
Estrogen is increasingly associated with long term prostate issues including cancer.
