Re: Testosterone ratio to Estrogen and risk of prostate cancer.

This is from a blog on the site,wwwtestosteronewisdom.com. Elsewhere there is a mention of using T replacement with caution in cases of Pca.


The normal production ratio of testosterone to estrogen is approximately 100:1. The normal ratio of testosterone to estrogen in the circulation is approximately 300:1. Estrogen (measured as estradiol) should be kept at 30 picograms per milliliter (pg/mL) or lower. As men grow older or as they gain a lot of fat mass, their estrogen blood levels increase, even to levels higher than that of postmenopausal women.

This is a site which speaks of a small study which suggests that use of estradiol reduces testosterone with fewer risks for osteoporosis and heart problems and, while enlarged breasts still occur, men had fewer complaints regarding hot flashes. That brings to mind the videos I've seen of Dr. Meyers. Maybe I got it all wrong, but it seems he promotes the use of estradiol and Testosterone therapy at the same time. I hope someone can clear this up for me. My primary doctor practices integrative medicine and we kicked around the idea of T. replacement. My urologist said my testosterone will go up now that I'm 'on vacation' from my injections. I decided to take DHEA, which converts to testosterone and estrogen, and my primary doctor has no problem with that.
