Several months ago, my friend Anna called to complain about her boyfriend of eight months. Bombarded by media warnings about the female biological clock, he wanted to make sure that Anna was fit for childbearing before the relationship moved forward. He had taken her to a fertility clinic where a reproductive endocrinologist drew blood to check her ovarian reserve and injected radioactive iodine into her uterus to ensure that her fallopian tubes were clear.

This occurs, however, not because of the woman's age but because women in their 30s, like Anna, tend to couple off with older men.
