What Is Estrogen Dominance?

Symptoms Seen In Men

Though estrogen is often associated with women, men also need a certain amount of estrogen to function. It's important for them to have a healthy balance of testosterone and estrogen for sexual development and growth. When there's too much estrogen, this balance is thrown out of whack. Men with too much estrogen might experience infertility, gynecomastia, and erectile dysfunction. Estrogen has a role in creating healthy sperm, but too-high estrogen can cause lower sperm levels, which leads to problems with fertility. Estrogen also stimulates the growth of breast tissue. If a man's estrogen levels are too high, it may be difficult to maintain or get an erection.
