It's not hot laptop computers on men's laps, a polluted environment, gynecological infections or a junk-food diet: The main reason for the rise in human infertility is an evolutionary battle between the sexes, according to a biologist at Tel Aviv University.

One in 10 couples are unable to conceive, and many external factors have been blamed.

About Catherine: I am mom to three grown sons, two grandchildren and two rescue dogs. After years of raising my boys as a single mom, I remarried a wonderful man who had never had a child of his own. Unexpectedly, I found myself pregnant at 49!
Sadly we lost that precious baby at 8 weeks, and decided to try again. Five more losses, turned down for donor egg, foster care and adoption due to my age and losses - we have accepted that there will be no more babies in our house.
