This is a useful and interesting article by Dr Jonathan Wright, a Harvard graduate, one of the fathers of bioidentical hormone therapy, in which the author claims:
For over 30 years, I’ve worked with men ages 45 and up whose symptoms and tests indicated a need for bio-identical testosterone. The results have been gratifying for everyone involved. Most notably, bio-identical testosterone therapy helps improve mood, attitude, cognitive ability, and general outlook on life. Many wives and families have observed that “Grandpa is a lot less grumpy,” remembers things better, and laughs and smiles a lot more often.
Plus, bio-identical testosterone improves muscle mass and strength, rebuilds bone, strengthens the heart and blood vessels, lowers total cholesterol and blood sugar, raises HDL (“good”) cholesterol, lowers blood pressure, lessens the chances of blood clots, improves tissue oxygenation, improves the health of a non-cancerous prostate gland-and that’s all before we get to testosterone’s positive effects on libido and your sex life.
