Scientists have assembled a lab system from living tissue that can replicate a woman's 28-day hormonal cycle. The goal is to use the system to find new ways to treat a host of women's health problems.

Cells that would die in a petri dish stayed alive for a standard 28-day reproductive cycle. The researchers jump-started the system's chemical communications with an injection of pituitary hormone.

A group of researchers recently decided to change that by studying more than 200 women to determine the effect of menstrual cycle phase and reproductive age on a woman’s likelihood of being ...

A simulated female reproductive system behaves almost like the real thing over 28 days. “Menstruation in a dish is one of my goals,” says Julie Kim of Northwestern University in Chicago.
