Men Have Biological Clocks, Too

As women wait longer to have babies, complications become more common, and now a new study says that men over 35 can contribute to these pregnancy problems. In intrauterine insemination, the woman’s age was closely associated with a decreased pregnancy rate and miscarriages, according to Dr. Stephanie Belloc of the Eylau Centre for Assisted Reproduction in Paris. And when the men were over 35, there also were increased miscarriage rates, most likely due to DNA damage that comes with age. So, if you and your guy want to have babies later in life—or if you were planning on bedding George Clooney—Dr. Belloc suggests you try in vitro fertilization. [EurekAlert!]
