Diabetes-linked hormones may also affect fertility

The hormones linked to diabetes might also influence a woman's fertility.

That's the finding in a new study in mice that determined the hormones leptin and insulin work together in the brain to control blood sugar levels, and in a surprise to researchers, also female fertility.

Scientists say the findings also appear to suggest that diabetes and obesity aren't always necessarily connected. They say the research provides new insight into how brain cells regulate glucose.

The study found that female mice, with the most brain cells that couldn't process the hormones, had trouble breeding and produced small litters.
