Proov Predict measures luteinizing hormone (LH), a marker in urine that tells you ovulation is about to occur. You’ll identify your LH surge to zero in on your two most fertile days, so you can try to conceive at the best possible time.

YO Sperm Tests provide insight into sperm quantity and quality to help identify issues — or rule them out — right up front.


Proov Confirm measures PdG, a marker of progesterone detectable in urine that rises after the peak fertile window, during the implantation window.  A clinical study* shows that elevated PdG on specific days after suspected ovulation (during the implantation window) increases the chance of successful pregnancy from 19% to 92%.
