Fast Facts
About this research study:
Join a research study at the NIH investigating how an FDA-approved medication may be used to help your body regulate hormones better.
Polycystic ovary syndrome (PCOS) is a hormonal disorder common among women of reproductive age. The combination of metabolic, hormonal, and psychosocial conditions can lead to infertility, skin problems, depression, and insulin resistance.

This National Institutes of Health research study is examining how daily treatment with special medication (mirabegron) will affect hormone sensitivity in women with this condition. We hope that this medication can improve your overall metabolic health as well as improve conditions associated with PCOS, such as infertility and weight gain.
