Processed meat, total meat consumption, and the hormones found in cow’s milk appear to increase risk for testicular cancer possibly due to contamination from alkylphenol endocrine-disrupting chemicals. Consumption of chicken (which contains phthalates) by pregnant women appears to negatively affect testicular development in utero. Consumption of meat during pregnancy may also affect a son’s fertility as an adult. Soymilk does not appear to have feminizing effects on men. Drinking cow’s milk, however, increases the estrogen levels in the body and causes men’s testosterone levels to drop. Xenoestrogens (human-made estrogenic chemicals) and dioxins appear to lower male sperm counts. Soy, on the other hand, does not reduce sperm count.
