Men often think incorrectly that only women have estrogen working in their bodies. Estrogen plays an important role in men. When men are younger they have higher levels of testosterone and lower levels of estrogen. As men age these levels shift causing decreased testosterone levels with corresponding elevated estrogen. We don’t discuss estrogen as a hormone that needs to be replaced in a man, but a hormone that needs to be controlled.

Men do need some estrogen for bone strength and it is also cardioprotective. But high levels can contribute to prostate cancer, heart disease, and gynecomastia. Testosterone is transformed into estrogen and can cause many frustrating symptoms: decreased muscle mass, low sex drive, erectile dysfunction, fatigue. Increased estrogen can also cause excess body fat leading to health issues such as diabetes and elevated lipids. For all these reasons we will closely monitor your estrogen levels making sure they are in the optimal range. If your estrogen levels are too high it may mean that they need to be decreased and then we need to explore why they were elevated.


  • Small amounts are needed.
  • High levels can be harmful.
  • Small correct amounts can protect the heart, prevent bone loss, and help with brain function.
  • Excess estrogen can be unhealthy.
  • Estrogen works against testosterone causing low sex drive, sore breasts, prostate enlargement, and even increased risk of prostate cancer.

As men age, estrogen levels increase and testosterone decreases. This and sedentary lifestyle allows for fat accumulation. Fat cells contain an enzyme called aromatase which converts testosterone to estrogen. The more fat cells you have the higher your estrogen can be.


When we are treating low testosterone during hormone replacement therapy, some of that testosterone can, not always and not common, convert to estrogen by the enzyme aromatase. Although, if you have excess belly fat you may have more issues with this conversion of testosterone to estrogen.

The doctors at Rejuvenate Hormone Clinic control estrogen levels by placing men of an estrogen blocking drug, also called an aromatase inhibitor, if needed. By stopping this conversion to estrogen your testosterone levels will increase.

Proper nutrition, changes in exercise, and natural supplements are also vital in keeping body fat low to remove aromatase. With a proper game plan, in a matter of months you will have lost belly fat and have stopped your conversion of testosterone to estrogen. The good news is that excessive estrogen levels in men are correctible and reversible with the help of our physicians.
