Are Your Sperm in Trouble?
Andrea Gore, a professor of pharmacology at the University of Texas at Austin and the editor of the journal Endocrinology, put it to me this way: “Semen quality and fertility in men have decreased. Not everyone who wants to reproduce will be able to. And the costs of male disorders to quality of life, and the economic burden to society, are inestimable.” Human and animal studies suggest that a crucial culprit is a common class of chemical called endocrine disruptors, found in plastics, cosmetics, couches, pesticides and countless other products. Because of the environmental links, The New Yorker once elegantly referred to the crisis as “silent sperm,” and innumerable studies over 25 years add to the concern that the world’s sperm are in trouble.
And so are men and boys. Apparently related to the problem of declining semen quality is an increase in testicular cancer in many countries; in undescended testicles; and in a congenital malformation of the penis called hypospadias (in which the urethra exits the side or base of the penis instead of the tip). These problems are often found together and are labeled testicular dysgenesis syndrome.
