Some studies show that as many as 6 to 7 percent of all males have used anabolic steroids before age 18 to build muscle mass. Anabolic steroids are really variations on testosterone. Taking these steroids is like a woman taking a birth control pill. In males, anabolic steroids tell the brain the testis is overworking and thus the brain reduces the release of FSH and LH, both of which are needed for normal sperm production. Extensive and extended use of anabolic steroids can result in permanent loss of sperm production and cause a man to become sterile. Many men will have return of sperm production, but it may take months. So anabolic steroids need to be avoided when a man is trying to father a child.
