Zinc levels in seminal plasma and their correlation with male infertility: A systematic review and meta-analysis
Zinc is an essential trace mineral for the normal functioning of the male reproductive system. Current studies have investigated the relationship between seminal plasma zinc and male infertility but have shown inconsistent results. Hence, we systematically searched PubMed, EMBASE, Science Direct/ Elsevier, CNKI and the Cochrane ...
Zinc Levels in Seminal Fluid in Infertile Males and its Relation with Serum Free Testosterone
Introduction: The role of zinc is critical to reproduction potential. Seminal zinc is thought to be derived almost exclusively from prostatic secretions. Sperm motility is significantly influenced by zinc. Zinc deficiency has been linked with male sterility and subfertility.
Aim: To assess the influence of seminal plasma zinc on seminogram charact...
The zinc spark is an inorganic signature of human egg activation
Egg activation refers to events required for transition of a gamete into an embryo, including establishment of the polyspermy block, completion of meiosis, entry into mitosis, selective recruitment and degradation of maternal mRNA, and pronuclear development. Here we show that zinc fluxes accompany human egg activation. We monitored calcium and zinc dynamics in individual ...
The role of vitamin D in reproductive dysfunction in women – a systematic review
