Male contraception: mechanical, hormonal and non-hormonal methods

Area of Science:

• Reproductive Health
• Endocrinology
• Pharmacology

Background:

• Effective and reversible male contraception is essential for global population stability and reproductive health initiatives.
• The World Health Organization prioritizes the development of novel male contraceptive methods.
• Hormonal male contraception aims to suppress gonadotropins while substituting testosterone to maintain sexual function and bone health.

Purpose of the Study:

• To review current strategies and promising future directions in male contraceptive development.
• To evaluate the efficacy of hormonal and non-hormonal approaches for male fertility regulation.

Main Methods:

• Review of existing literature on hormonal male contraception, including testosterone monotherapy, androgen/progestin combinations, testosterone with gonadotropin-releasing hormone (GnRH) analogs, and selective androgen and progestin receptor modulators.
• Exploration of non-hormonal contraceptive strategies.

Main Results:

• Complete interruption of spermatogenesis requires adequate suppression of intratesticular testosterone production.
• Testosterone and progestogen combinations are currently the most promising hormonal approach.
• Several non-hormonal methods show potential for future male contraceptive development.

Conclusions:

• Hormonal male contraception, particularly testosterone and progestogen combinations, offers a viable path for effective fertility control.
• Non-hormonal approaches represent a significant area for future research and development in male contraception.
