Chemotherapy drug could reduce fertility of unborn baby

A chemotherapy drug given to pregnant cancer patients could reduce the fertility of unborn baby girls, a new study suggests.

Researchers found that a drug called etoposide can damage the development of ovary tissue in mice.

Etoposide is used to treat several types of cancer and is considered safe for use in the second and third trimester of pregnancy because it has a low risk of miscarriage and birth defects.
