GYNECOMASTIA AND WAYS TO PREVENT IT

Abstract

Gynecomastia is caused by excessive levels of estrogen. This female sex hormone rises to exceptionally high levels with steroids, due to high levels of aromatization (conversion of testosterone to estrogen).
In an attempt to prevent gynecomastia, bodybuilders often take an AI (aromatase inhibitor) or a SERM (selective estrogen receptor modulator). AI works by blocking the conversion of testosterone to estrogen, while SERMs do not stop this conversion, but directly inhibit the effects of estrogen in the mammary glands.

SERMs are often preferred, due to the possible worsening of hypertension of AI; with high estrogen levels having a positive impact on HDL cholesterol.
