Apple Women's Health Study for Menstrual Cycle and Gynecologic Health

This is an observational study called the Apple Women's Health Study. It aims to better understand menstrual cycles and gynecologic (female reproductive system) health conditions like Polycystic Ovary Syndrome (PCOS), infertility, and breast cancer. There are no specific interventions or drugs being tested. The study is looking for 500,000 participants of all genders, aged 18 and older (with some age exceptions for certain states/territories), who have menstruated at least once, live in the U.S., can communicate in English, and have an iPhone with the Apple Research app installed. The study will be considered successful if it can identify patterns in menstrual cycles and provide a detailed description of menstrual cycle health over up to 10 years. The current recruitment status is unclear.
