Ava has not been tested for polycystic ovary syndrome (PCOS).

 If you have mild PCOS and your cycles are within 24 – 35 days, Ava may work for you but we have not done any testing to confirm this. If your cycles are outside of this range, Ava's built-in fertility detection feature will not be accurate for you. However, you may find the health data provided in the Ava app to be useful in identifying your fertile window on your own.
