Years ago it was anabolic steroids that took the limelight in terms of muscle growth, competitive bodybuilding and fertility. Anabolic steroids can cause a long list of side effects, including infertility and death, but prohormones – the close cousins of anabolic steroids, could be just as dangerous. Prohormones are chemical substances created in a lab to mimic testosterone. The federal government attempted to ban prohormones, but all it takes is a little chemistry knowledge to create derivatives of the banned supplement. There is no way for the government to keep up with all the prohormones, especially since some products claiming to be prohormones aren't really prohormones at all. The world of prohormones, steroids and athletics can be extremely confusing, but one thing is certain – prohormones can cause infertility.

Prohormones and Infertility
Prohormones have been around for a number of years, but the general public didn't know much about the supplements until 1998 when Mark McGwire of the Oakland Athletics admitted to taking performance-enhancing drugs, including prohormones. The term prohormone simply means a substance that converts to a hormone, particularly an anabolic hormone that may increase muscle growth and strength. The effects of prohormones on the muscle peak during use and then disappear gradually after a supplement cycle is stopped. However, the negative side effects, including kidney damage, liver damage and infertility may last well beyond the cycle.


How to Prevent Infertility from Supplements and Drugs
The simplest way to prevent infertility caused by prohormones is to never take prohormones. While the Food and Drug Administration has theoretically banned all prohormones, they cannot keep up with synthetic substances hitting the supplement market. A chemist can take a banned prohormone and alter a few bonds to create a new prohormone. It hits the market for a while then the company pulls it if there is any threat from the FDA and releases a new product. Healthy alternatives to prohormones that have no known effect on fertility include creatine and protein.
