Ten to fifteen percent of couples desiring to start a family discover that they are infertile. In about half of these cases, the husband is found to be the one infertile. Increasing the intake of saturated fat by just 5 percent was observed with a 38 percent lower sperm count in a recent Harvard Study. Infertility rates are also higher in couples that eat meat frequently. Dr. Michael Greger says that researchers believe that this may be due to endocrine-disrupting industrial pollutants such as pesticides and dioxin-like pollutants and steroids that build up in the fat of animals, especially fish. These chemicals can have adverse effects on male reproductive capability. This can even include the chemicals that may be present in the plastic wrap.
Research shows that frequent meat and dairy consumption "may negatively affect semen quality in humans" and that fruit and vegetable consumption "improves semen quality," due to its nutrient and antioxidant content. A statement made by the American Society for Reproductive Medicine stated that "Couples seeking assisted reproduction treatments must be advised about the drastic effect of both the male and female lifestyle on treatment success."
Dr. Greger also discusses how heavy metals like lead and cadmium are associated with infertility. High levels of cadmium are found in tuna, and the highest levels of lead are found in scallops and shrimp.
