High estrogen levels in men generally occur as a
result of conversion from testosterone. An
enzyme called aromatase causes testosterone to be changed into estradiol. Aromatase lives in the fat cells, so men who carry extra weight around the middle tend to have more cortisol and consequently make more estradiol. Cortisol increases the activity of the aromatase enzyme, so high cortisol levels can also lead more testosterone to be converted into estradiol. Thus, weight loss and stress reduction are important steps in restoring the balance of hormones.
