Predict and confirm
your ovulation with
actual data

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

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.

Frequently Asked Questions

WHAT RESULTS DOES INITO GIVE?

Inito gives results as: High Fertility, Peak Fertility or Ovulation Confirmed. Inito also shows you the charts and actual values of all 4 hormones.

WILL INITO WORK IF I HAVE PCOS?

Every woman is unique, especially with a condition like PCOS, which can influence hormone levels. Inito shows you a full picture of your cycle, which can help you identify your fertile days and confirm ovulation.

DO I NEED TO USE A TEST STRIP FOR EACH HORMONE?

No. Inito is the only fertility monitor that measures Estrogen, LH, PdG (urine metabolite of progesterone) and FSH on a single test strip.

DO MEDICATIONS AFFECT THE RESULTS?

Fertility medications or other drugs that influence your hormones can prevent Inito from giving you accurate results. You will still be able to see your hormone patterns via the App.
