The main challenge in chemical male contraceptives is targeting spermatogenesis without systemic side effects
Recent advancements in non-hormonal and hormonal male contraceptives focus heavily on precisely targeting spermatogenesis and sperm maturation while avoiding systemic side effects.
The retrieved literature consistently emphasizes that developing novel male contraceptives involves finding specific targets within the testis, epididymis, or hormonal axes that disrupt spermatogenesis effectively and reversibly while maintaining a favorable safety profile and avoiding systemic toxicity.
