Men Should Consider Biological Clock as Well

In Start Your Family, I (Steve) talk about the strong urge Candice felt to have a baby and how I got her to “hit snooze on her biological clock.” It’s those potent emotions about having children, as well as a broad range of headlines about fertility and the timing of babies, that make us so aware of a woman’s biological clock. Increasingly, however, news reports are explaining that men also have a biological clock to keep in mind.

“It wasn’t all that long ago that any suggestion that a man had a ‘biological clock’ like a woman, and should father children sooner rather than later, would have been given short scientific shrift,” says a new article by U.S. News and World Report. “Not anymore. Today, a growing body of evidence suggests that as men get older, fertility can and does decline, while the chances of fathering a child with serious birth defects and medical problems increase.”

The article sources Dr. Harry Fisch, author of the book The Male Biological Clock with the finding that after age 30, testosterone levels decline about 1 percent per year. Fisch doesn’t come out and recommend an ideal age for men to start a family, but where men have a choice in the matter, Fisch suggests “the sooner, the better.”
