Summary

A woman's cache of eggs drops precipitously right around her 37th birthday, but the reasons have always been puzzling. Researchers are converging on one new and eminently logical answer: The ovary's ability to repair damaged DNA may decline over time, and with it, the survival of its eggs. A new study of mice and humans whose natural ability to fix DNA is impaired, published this week in Science Translational Medicine, bolsters this theory.
