In the male, a common side effect of anabolic steroid use is impotence and erectile dysfunction. Sperm count is also significantly affected. Hormones critical to the process of sperm production are significantly affected by the use of anabolic steroids and, the greater the amount of steroids taken, the greater the impact on the hormone pattern. Reduced fertility caused by steroids is something that very few men appreciate. The need to look good or perform well in the athletic arena often clouds judgment. It is not until they choose to begin a family that their habit begins to haunt them.
The Mesterolone hormone is not estrogenic. It does not aromatize and it carries no progestin nature. As a result, the side effects of Proviron will not include any related effects such as gynecomastia or excess water retention. Such adverse effects are impossible with this steroid. This will also greatly reduce the risk of high blood pressure as high blood pressure associated with anabolic steroid use is often due to extreme water retention. In fact, Proviron should provide an anti-estrogenic effect by preventing testosterone to estrogen conversion or at least tremendously slow it down.
