Apple Women’s Health Study

Why is this study being done?

In the first study of its kind, researchers at the Harvard T.H. Chan School of Public Health, Apple, and National Institute of Environmental Health Sciences (NIEHS) launched the Apple Women’s Health Study to gain a deeper understanding of how certain demographic and lifestyle factors could have an impact on menstrual cycles and gynecologic conditions including infertility, menopause, and polycystic ovary syndrome (PCOS).
