A new study by Swedish researchers has reported that certain hormone-blocking drugs to reduce the risk of breast cancer recurrences impact a woman’s sex life. Researchers affiliated with Örebo University Hospital (Örebo, Sweden) published their findings online on September 17 in the journal Menopause.
The goal of the study was to evaluate the effect of aromatase inhibitors on the sexual function of postmenopausal breast cancer patients. Aromatase is the enzyme which manufactures estrogen. Many breast and ovarian cancers require estrogen to grow; thus, aromatase inhibitors are taken to either block the production of estrogen or block the action of estrogen on receptors.
