Most ovulation tests predict your fertile days by tracking Luteinizing Hormone (LH), but fail to measure the hormone that actually confirms your ovulation: PdG (urine metabolite of progesterone).

Unlike most ovulation tests that only give you "yes/no" results, Inito provides real numerical values of your fertility hormones.

If you have irregular cycles, actual data is necessary to know exactly when you ovulate, and when is the best time to try to conceive.

WHY MEASURE PdG (URINE
METABOLITE OF PROGESTERONE)?

WHY MEASURE PdG (URINE METABOLITE OF PROGESTERONE)?

Anovulation (having a menstrual
cycle with no egg) is actually a common occurrence, affecting 1 in 10 women*.

Anovulation (having a menstrual cycle with no egg) is actually a common occurrence, affecting 1 in 10 women*.

If ovulation occurs, the levels of Progesterone and its urine metabolite PdG rise after a few days and stay elevated. Sustained, elevated PdG levels after peak fertility indicate a successful ovulation.

I was using the store brand ovulation test and I was
not getting pregnant, even though I kept getting the
“blinking and solid smiley face”.

I purchased Inito and realized that I was not ovulating every month. […] I was able to bring my Inito information and my exact hormone levels to my OB Dr and she was able to prescribe me medication to help me ovulate.
