The abuse of anabolic steroids by high school, college and other amateur athletes is a dangerous practice. Participants in amateur sports must be made aware of the physical and emotional dangers associated with steroid abuse. The "win at any cost " attitude embraced by some athletes must be redirected and replaced by personal dedication to the sport; a thorough knowledge of the sport's physical demands and requirements; maintenance of a healthy lifestyle; and, an appreciation of the satisfaction that comes from participation.
Endocrine side effects have included inhibition of endogenous testosterone release by means of feedback inhibition of pituitary luteinizing hormone (LH). Large doses of exogenous anabolic steroids may suppress spermatogenesis through inhibition of pituitary follicle stimulating hormone (FSH). The androgenic activity of anabolic steroids may decrease levels of thyroxin-binding globulin and result in decreased total T4 serum levels and increased resin uptake of T3 and T4. Free thyroid hormone levels remain unchanged and there is no clinical evidence of thyroid dysfunction. [ Ref ]
