At a Glance

The Mira Fertility Plus is the single most important advancement in ovulation testing for PCOS. Instead of comparing LH to a fixed threshold (which fails in PCOS because baseline LH is already elevated), Mira measures actual quantitative hormone concentrations in mIU/mL — the same data your gynecologist uses. Its AI algorithm learns your personal hormone pattern over multiple cycles, distinguishing true LH surges from chronic LH elevation. Also tracks estrogen. Multiple fertility specialists specifically recommend Mira for PCOS patients.
