How much Zinc is lost in ejaculate ?

[chipdouglas]

Dr. Mariano,

What are the chances one can bring Zinc depletion upon himself through daily ejaculation, assuming one has a balanced healthy diet including nuts, meat (mostly poultry) ?

Googling this, I found numbers to be all over the place.

I once asked Dr. Kevin Pezzi, and I recall he at the time provided me with some document showing how little Zn is lost in ejaculate, however I appear to have lost this document.

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.

Thanks

What I think from remembering the document Dr. Pezzi sent me a while ago is that not much zinc is lost in ejaculate. Some claim it’s much higher 5 mg, but I’d like the see the evidence.

I haven’t heard of anyone actually measuring the amount of zinc in sperm using a mass spectrometer.

If a person had a nutritionally dense diet, I doubt that zinc loss in sperm would be a problem.
