Guide for assessing and treating testosterone deficiency in adult men

madman

Super Moderator
Testosterone therapy improves various aspects of health, including sexual function, bone density, anemia, muscle mass, physical function, mood, and cognitive function, and reduces the risk of type 2 diabetes. It does not increase the risk of prostate cancer or cardiovascular problems. Evidence suggests potential cardiovascular benefits, especially for men with kidney disease, atrial fibrillation, or a history of heart attack. Long-term studies are needed for further clarification. Recent studies indicate that testosterone therapy, along with metformin, may reduce the occurrence of prostate and colorectal cancer.

*It is important to ask about the loss of early morning erections even in men not in a sexual relationship, as absent early morning erections are an important predictor of future cardiovascular events.6

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
