There are some drugs, both legal and illegal, that can have a negative impact on male fertility. Anabolic steroids are used to decrease body fat and increase muscle mass. Also known as anabolic-androgenic steroids, these drugs are being used among non-competitive athletes and non-athletes. Testosterone is an anabolic steroid.
These types of steroids can do damage to male fertility. The drugs interfere with the hormone signals required to produce sperm. The amount of damage depends on which drugs are being used, the dosage, and how often they are taken. Anabolic steroids can be found in some fitness and muscle-building dietary supplements from unregulated companies.
Excessive amounts of anabolic steroids may help you achieve a more muscle-bound physique; however, at the same time, they can also lower your sperm count considerably. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are important hormones in sperm production. These drugs affect FSH and LH, and in some men, will completely diminish sperm to the point where there are no sperm in the ejaculate.
