infertility

When Sarah Gardner was 34, she started getting worried about whether she'd ever have a baby. So she took a test that aims to measure a woman's fertility.

The results terrified her. They indicated she had the fertility of a woman a decade older — a woman in her mid-40s.

"I was devastated," Gardner says. The news hit her especially hard because she was in the midst of breaking up with her longtime boyfriend.

It turns out humans and cattle have some of the same fertility issues.

Researchers at Washington State University have received more than a million dollars from the National Institutes of Health to look into what causes lost pregnancies in beef cattle - and also what that can teach us about miscarriages in humans.
