    Some info on link between zinc and male androgens/estrogen balance, testosterone levels, semen and ejaculation.
    How much zinc is lost during a single ejaculation? I've seen estimates of between 1mg and 15mg of elemental zinc, what is sure is that there is a relevant net loss.

    Effects of dietary zinc depletion on seminal volume and zinc loss, serum testosterone concentrations, and sperm morphology in young men.

    Identification of the andrological variables most sensitive to zinc depletion would expedite the diagnosis of male reproductive pathology induced by zinc deficiency. Eleven volunteers living on a metabolic ward were fed a diet composed of a mixture of a semisynthetic formula and conventional foods supplemented with ZnSO4 to supply a total of 1.4, 2.5, 3.4, 4.4, or 10.4 mg Zn/d. After an equilibration period of 28 d (10.4 mg Zn/d), all treatments were presented for 35 d each, the first four in random order and the fifth last. Compared with when they were consuming 10.4 mg Zn/d, volunteers consuming 1.4 mg Zn/d exhibited decreased semen volumes (3.30 vs 2.24 mL) and serum testosterone concentrations (26.9 vs 21.9 nmol/L), and no change in seminal zinc concentrations. Compared with 10.4 mg Zn/d, treatments of 1.4, 2.5, and 3.4 mg Zn/d decreased the total semen zinc loss per ejaculate (6.29 vs 3.81, 4.68, and 5.03 mumols/ejaculate). Seminal loss accounted for 9% of total body zinc loss when 1.4 mg Zn/d was consumed. Seminal phosphorus concentrations were elevated during all four phases of zinc depletion (28.4 vs 32.9, 31.0, 34.2, and 33.6 mmol/L). The findings suggest that serum testosterone concentrations, seminal volume, and total seminal zinc loss per ejaculate are sensitive to short-term zinc depletion in young men.

    Biological role

    Zinc is an essential element in human beings, necessary for sustaining life. Deficiencies of zinc have marked effects on weight gain in animals. Zinc is found in insulin, zinc finger proteins, and such enzymes as superoxide dismutase.

    According to some sources, taking zinc tablets may provide some immunity against colds and flu, although this is disputed.

    Eyesight, taste, smell and memory are also connected with zinc and a deficiency in zinc can cause malfunctions of these organs and functions.

    Natural food sources of zinc include oysters, red meat and poultry, beans, nuts, whole grains, pumpkin seed or sunflower seeds.

    In males, zinc is important for the production of semen. Up to 5 mg of zinc is lost during ejaculation. Deficiencies in zinc in males can lead to reduced sperm count and sex drive. Frequent ejaculations can lead to zinc deficiency.

    So if on a viagra binge, also binge on zinc, :)
    Zinc is Apart of the reason why meat is good for men, as well as the fat content for hormone production is important too. Good testosterone levels help improve recovery, insulin sensitivity etc etc, not just a stallion in bed :)

    good info baccarat.

    Zinc is also an aromatase inhibitor.
