Meat-Eating Moms Have Less Fertile Sons

 

A new study in Human Reproduction finds that a pregnant woman's meat

consumption can reduce her future son's sperm count. Researchers at the

University of Rochester analyzed the relationship between various sperm

parameters of 387 men and the eating habits of their mothers from the Study for

Future Families. The more beef a mother consumed, the lower her son's sperm

concentration. Sperm count was 24 percent higher in men whose mothers consumed

less beef. The difference may be due to steroid hormones found in animal

products. Six hormones are commonly used in the United States to induce

increased growth and development in cows, and measurable levels are routinely

present in the animals' muscle, fat, livers, kidneys, and other organs. Cows

raised without extra hormones still have significant hormone levels in their

tissues due to endogenous hormone production.
