Trestolone
Trestolone (7α-methyl-19-nortestosterone) is a synthetic androgen developed by the Population Council as a potential candidate drug for use in hormonal male contraceptive methods. In males, regular administration of sufficient quantities of trestolone induces a state of temporary infertility.
Additional recommended knowledgeMechanism of actionAs a derivative of the anabolic steroid hormone nandrolone, trestolone's viability as a male contraceptive is twofold. Inhibition of sperm productionSpermatozoa are produced in the testes of males in a process called spermatogenesis. In order to render a man infertile, a hormone-based male contraceptive method must stop spermatogenesis by interrupting the release of gonadotropins from the pituitary gland. Even in low concetrations, trestolone is a potent inhibitor of the release of the gonadotropin hormones, luteinizing hormone (LH) and follicle stimulating hormone (FSH).[citation needed]
Support of secondary sex characteristicsWhen LH release is inhibited, the amount of testosterone made in the testes declines dramatically. As a result of trestolone's gonadotropin-suppressing qualities, levels of serum testosterone fall sharply in patients. Testosterone is the primary hormone responsible for maintenance of male secondary sex characteristics. Normally, inadequate testosterone levels cause undesirable effects, such as fatigue, loss of skeletal muscle mass, reduced libido, and weight gain. However, the androgenic and anabolic properties of trestolone largely ameliorate this problem. Essentially, trestolone replaces testosterone's role as the primary male hormone in the body.
