The zinc mineral plays a strong role in male reproductive health Even a mild zinc deficiency has been associated with decreased testosterone levels in men, low sperm concentrations in semen and a reduction in lean body mass. Research on masculine issues has also shown that increasing zinc consumption can reverse these negative effects.
Role of zinc in reproductive health
Zinc plays many roles in the human body, including a role in reproduction. This is largely because zinc helps in the synthesis of testosterone. In men, the testicles need it to function properly. Severe zinc deficiency compromises a man's ability to produce sperm, and this, in turn, could compromise general fertility. A study on mice in 2011 published in the "Journal of Nutrition" found that a diet low in zinc was associated with fertility problems independent of circulating levels of zinc or testosterone.
Low zinc, low testosterone
For decades, scientists have been establishing a correlation between low testosterone levels and zinc deficiency. A 1992 study involving 11 volunteers found that zinc depletion, even in the short term, could reduce testosterone levels in young men. The most recent research, a 2011 study published in the journal "Biological Trace Element Research," found that men with normal testosterone levels had significantly higher levels of zinc than men with low blood levels. testosterone And those with low levels were more likely to have lower levels of testosterone, according to a 2012 study of men between 25 and 55 years of age that was published in the "African Journal of Medicine and Medical Sciences." Medicine and Medical Sciences).
Zinc and Testosterone Supplements
A study published in the "Nigerian Journal of Physiological Science" in 2013 found that rats given zinc supplements for six weeks showed levels of testosterone increased significantly compared to rats that did not receive zinc supplements. The animals that took zinc had also improved the quality of the sperm. In a human study, researchers at Wayne State University looked at the relationship between zinc levels and testosterone in healthy men ages 20 and 80. After 20 weeks of zinc restriction, the youngsters showed a significant decrease in testosterone concentration, while the older men who took zinc supplements during this time increased their testosterone levels.The research was published in the journal "Nutrition" (Nutrition).
The US National Research Council recommends taking 15 milligrams of zinc daily for adult women and men. Zinc deficiency can lead to problems in the immune system, reduced lean body mass and low testosterone levels. Atrophied growth and cognitive decline can also cause zinc deficiency. Severe zinc deficiency could lead to alopecia (hair loss), diarrhea, emotional disorders, weight loss, infections, hypogonadism in men and problems with ulcer healing.
