Fish and other seafood contribute pollutants that may interfere with male fertility by lowering sperm count and sperm quality. The antioxidant amino acid, ergothioneine, may have a positive effect on sperm quality as it concentrates in semen and in other sites of oxidative stress. Hormones in meat, especially chicken, are associated with ovulatory infertility in women; consumption during pregnancy may alter testicular development of a male fetus and produce behavioral disorders. Soy phytoestrogens do not decrease sperm count and, in fact, vegetable protein may increase fertility. But GMO soy is commonly contaminated with Monsanto’s Roundup and this herbicide has been shown to disrupt embryonic development of rat testicles. Cow’s milk is of particular concern because of its hormones, and may be the reason that women on conventional diets have five times the rate of twin births than vegan women. Breast pain and other menstrual discomforts may be linked to prolactin in meat and may be ameliorated by eating flax seed and a plant-based diet. We may be able to achieve the same results as caloric restriction, which include slower aging and maintaining youthful levels of the hormone DHEA by eliminating eggs and adopting a more plant-based diet.
