What role does zinc play in men?

Zinc plays a significant role in male health, influencing various aspects of reproductive and overall well-being:

1. Testosterone and Spermatogenesis: Zinc is highly enriched in the testes. It impacts key enzymatic functions, including androgen-binding proteins, thereby boosting spermatogenesis and testosterone levels. Zinc supplementation has been shown to increase sperm count, testosterone levels, and even testicular size. However, it's crucial to take zinc with meals to avoid nausea 1.

2. Sperm Quality: Zinc, alongside other antioxidants, improves sperm concentration, quality, motility, and morphology. This enhances the chances of conception and the likelihood of a live birth when taken prior to conception. Improving antioxidant status in men, including zinc intake, is crucial for fertility 2.

3. Hormonal Regulation and Fertility: Zinc is essential in maintaining testosterone levels and detoxifying foreign estrogens. High zinc levels are associated with enhanced fertility and greater “maleness”, significantly impacting androgenic functions 3.
