Is Zink useful for fertility?

Zinc is an essential trace element involved in numerous bodily processes, including fertility. In men, zinc supports sperm production and maturation; deficiency can impair sperm quality. In women, zinc contributes to egg maturation and hormonal balance. However, the evidence for zinc supplementation improving fertility is mixed. Most benefits are seen in individuals with confirmed zinc deficiency. For those with adequate levels, extra zinc likely offers no advantage. High doses can be toxic and interfere with copper absorption. Therefore, a blood test before supplementation is advisable. The evidence level is moderate: human studies exist but no strong universal recommendation. In summary, zinc is important but not a fertility cure-all. Correcting a deficiency is beneficial; avoid excess.
