Hormonal male contraception

Christina Wang et al. Andrology. 2024 Oct.

Abstract

Introduction: Male contraception with exogenously administered hormones suppresses both luteinizing hormone and follicle stimulating hormone leading to low intratesticular testosterone concentration. This results in reversible suppression of spermatogenesis and marked decrease in sperm output in the ejaculate and preventing pregnancy in the female partner.

Prior studies: Studies of testosterone administered alone or in combination of another gonadotropin suppressive agent such as a progestin or gonadotropin releasing hormone (GnRH) analog showed decisively that the exogenous hormone administrations are effective in suppressing sperm output with few adverse events that are not anticipated. In contraceptive efficacy studies, testosterone alone or combined with a progestin are as effective in preventing pregnancies as female contraceptive methods.

Conclusion: Hormone combinations for male contraception are in late-phase clinical trials and hold the promise of being the new, reversible contraception method for men in over half a century. Lessons learned from the male hormonal contraceptive development pave the way for new targeted approached to regulate male fertility.

Keywords: gonadotropin releasing hormone analogs; modified androgens; progestin; spermatogenesis suppression; testosterone.
