Role of micronutrients in reproduction

Micronutrient Mechanismrmetabolic function Deficiency consequences

Vitamin E Intra-membrane free radical Low sperm concentration and detoxification high incidence of cytoplasmic droplets, retained foetal membrane
Selenium Component of GSH-Px Reduced sperm motility and uterine contraction, cystic ovaries, low fertility rate retained foetal membrane
Copper Enzyme component and catalyst Low fertility, delayedrdepressed involved in steroidogenesis, and oestrus, abortionrfoetal prostaglandin synthesis resorption
Zinc Constituent of several metallo- Impaired spermatogenesis and enzymes; steroidogenesis, development of secondary sex carbohydrate and protein organs in males, reduced fertility metabolism and litter size in multiparous species
