Determined not to make the same mistakes that he did with his first family, Jeff began anew with his third wife. Jeff just turned 60.
Devastated by the loss of their only son, Edward and his wife -- both in their late 40s -- decided to have more children.
For a whole host of reasons, a growing number of men are opting to become later-in-life fathers. They join the ranks of such famous older dads as David Letterman, Tony Randall, Larry King, Anthony Quinn, Woody Allen, Charlie Chaplin, Warren Beatty, Jack Nicholson, and Nobel Prize-winning author Saul Bellow.
The majority of children are still being born to men who are 20 to 34, but a December 2003 National Vital Statistics Report indicates that birthrates among fathers aged 35 to 49 increased slightly from 2001 to 2002. Between 1980 and 2002, the rate of births among fathers aged 40 to 44 went up 32%, and for fathers aged 45 to 49, 21%. For men 50 to 54, the increase was 9%.
This mirrors what New York City male fertility expert Marc Goldstein, MD, sees in his practice. "I am seeing more older men waiting longer to get married or who are divorced and remarried, [including] the CEOs who are discarding their last trophy wife for new ones," says Goldstein, a professor of reproductive medicine and urology at Weill Cornell Medical College and the surgeon-in-chief of male reproductive medicine and microsurgery at New York-Presbyterian Hospital/Weill Cornell Medical Center. Goldstein's oldest patient was 87.
Setting the Male Biological Clock
While much ado is made about women's fertility declining with advancing age, what about men?
Many men will have no problems conceiving a healthy child, but "there is quite a bit of evidence that advancing age can affect the DNA or genetic material in sperm," Goldstein says. This damage may start as early as age 35 and worsens with age. As a result, older men may father children who have higher rates of schizophrenia and/or Down syndrome, he says.
