Men: The Importance of Knowing Your Estrogen Level

MattDr. Mike's TipsLeave a Comment

Men need a certain amount of estrogen. For men, estrogen (specifically, estradiol) begins in the testes as well as through extra-glandular (outside the gland) conversion of androgens. But if a male body converts more testosterone to estrogen than required, the levels become too high. Consequently, the estrogen interferes with whatever free testosterone exists and both hormones compete for receptor sites. In these cases, there are ways of blocking the estrogen and the problem is easily solved.

Through enzymatic action, testosterone can convert to two other hormones: dihydrotestosterone (DHT) and estrogen. The enzyme 5-alpha reductase (found in high concentrations in the prostate gland and skin) converts testosterone into DHT. Aromatase (found in skin, brain, fat and bone) transforms the hormone into estrogen (estradiol).

As years pass, increasingly more testosterone converts to estradiol, increasing a man’s risk for prostate cancer, heart disease and stroke.

One report compared estrogen levels of both genders, showing an average 54-year-old man’s to be higher than an average 59-year-old woman’s.

Since estrogen levels increase with age, men never need estrogen therapy. Actually, aging men often suffer the effects of too little testosterone and too much estrogen. The resulting imbalance directly causes many debilitating health and performance problems associated with “normal” aging.

Since testosterone increasingly converts to estrogen as men age, taking testosterone by itself, without monitoring other hormones, is not judicious. Testosterone may convert into even more estrogen, a process called aromatization.

Aromatization potentially worsens the already existing hormone imbalance. Too much estrogen and not enough testosterone can increase risk of a heart attack or stroke. High levels of estrogen also have been implicated as a cause of benign prostate hyperplasia (noncancerous enlargement of prostate) and even prostate cancer.

A Comprehensive Age Management Evaluation and Program allows us to appropriately optimize and follow estrogen as well as your other hormone levels as an integral part of your overall care plan. If you’re in the West Hollywood, Beverly Hills, or Los Angeles area, schedule an evaluation with Age Management / Hormonal Optimization expert Dr. Mike Carragher. If you live out of the area, we can take care of you as well, requiring only an annual visit to The Body Well for your anti-aging Age Management Program. Dr. Carragher will request a blood panel, schedule a comprehensive evaluation, and discuss the best individual treatment options for you.
