Background

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.

Mechanism of action

Trestolone is a potent inhibitor of the release of the luteinizing hormone (LH) and follicle stimulating hormone (FSH). As spermatogenesis requires both testosterone and FSH, it is impaired by the reduction in FSH caused by trestolone as well as the reduction in LH, and subsequent reduction in testosterone.
