[Perspectives of male contraception]

Area of Science:

• Reproductive biology
• Pharmacology
• Contraceptive development

Background:

• Male contraception research focuses on inhibiting sperm production or function.
• Hormonal methods, particularly steroid blockade of spermatogenesis, are a key area of investigation.

Purpose of the Study:

• To review current and emerging strategies for male contraception.
• To project the potential availability of novel male contraceptive methods.

Main Methods:

• Review of hormonal, chemical, physical, and immunological approaches.
• Analysis of research on steroid blockade, calcium channel inhibitors, and reversible vasectomy.

Main Results:

• Steroid blockade of spermatogenesis is a promising hormonal approach.
• Pharmacological inhibition of calcium channels offers another avenue for sperm function control.
• Reversible vasectomy may become a viable option based on recent research.

Conclusions:

• Male hormonal contraceptives (injections/implants) may be available within ten years.
• A male oral contraceptive pill is unlikely in the near future.
• Advancements in reversible vasectomy and calcium channel blockers present future male contraceptive possibilities.
