Aromatase Inhibitors Linked to Low Sexual Desire, Bowel Problems

Feb 19, 2018

Aromatase Inhibitors Linked to Low Sexual Desire, Bowel Problems Women who take drugs called aromatase inhibitors (AIs) for breast cancer are more likely to have low sexual desire and trouble with bowel movements, even ten years after their cancer diagnosis, experts report.

AIs are used by post-menopausal women with hormone receptor positive breast cancer. With this type of cancer, hormones like estrogen fuel the growth of cancer cells. AIs work by reducing the amount of estrogen in a woman’s body, thus limiting the estrogen available to cancer cells.

The drugs are usually taken for five years, although some women take tamoxifen (another breast cancer drug) for two or three years beforehand. AIs can be taken for up to ten years after cancer diagnosis.
