Zinc has been shown to help couples with fertility issues. Large doses of zinc, about 50 milligrams, may cause an increase in semen. Taking zinc supplements is especially advantageous for men with a low sperm count. For women, taking zinc supplements may increase the likelihood of conception by having an effect on the hormone levels in the body.

The highest zinc content is found in oysters. But meats such as liver, chicken, and turkey also are very good sources of zinc, so it is unlikely that people have a deficiency of zinc. There are also significant levels of zinc in dairy products. Since vegetarians do not eat meat, they are at the greatest risk of having a zinc deficiency. For adults, not having an appropriate amount of zinc in the system may cause changes in the condition of hair and skin, and it will depress the appetite. Other people may have trouble absorbing zinc, including people who are hospitalized and are receiving nutrients via a feeding tube, alcoholics, and women taking birth control pills.

This method of treating fertility issues should not be commenced without having first consulted a medical professional. Large doses of zinc supplements may affect copper absorption in the body and therefore have a negative effect on the immune system. Further, large doses of zinc may decrease the quantity of high-density, or good, cholesterol in the bloodstream. And if you are on any medication, taking zinc supplements is probably not a good idea.
