Zinc therapy (5 mg/day) improves sexual competence by increasing penile thrusting and prolonging ejaculatory latency without disturbing arousability and motivation of male rats. Increase in the T levels observed with zinc supplementation is beneficial in this regard. However, increase in PRL is responsible for the reduced libido index. Further studies on pigs and monkeys are needed to evaluate the possible therapeutic use of zinc in sexual dysfunction.
Low levels of zinc can be the cause for a variety of health-related problems. Zinc is a key mineral that cells use to metabolize nutrients. Immune function, DNA and protein production, and cell division are all related to zinc levels in the body. Zinc also enables the male body to produce testosterone. Because of this, your levels of zinc may affect erectile dysfunction.
