Chromosomal Problems

Up to 70 percent of first trimester miscarriages and 20 percent of second trimester miscarriages occur because of a glitch in the fetus's genes, according to the March of Dimes. "It's still a mystery to us," says Jonathan Schaffir, MD, an assistant professor of obstetrics and gynecology at Ohio State University College of Medicine, "but sometimes the two sets of chromosomes from the egg and the sperm don't line up right at the moment of conception. It doesn't mean that anything's wrong with the mother or father -- or that it will necessarily happen the next time.
