How are Zink and Fruchtbarkeit related?

Zinc is an essential trace element that plays a critical role in fertility for both men and women. In men, zinc is vital for sperm production, maturation, and motility. Zinc deficiency is linked to reduced sperm quality, lower sperm count, and increased DNA fragmentation in sperm. In women, zinc supports egg maturation, ovulation, and hormone regulation, particularly estrogen and progesterone synthesis. Zinc also acts as an antioxidant, protecting reproductive cells from oxidative stress. Studies indicate that adequate zinc intake can improve fertility outcomes, while deficiency is associated with infertility. The evidence is based on human observational and interventional studies, though it is not always conclusive because zinc often works synergistically with other nutrients. A blood test to check zinc levels is advisable before supplementation. Caveat: Excessive zinc intake can be toxic and impair copper absorption.
