Frequently asked

What is LH and why should I measure it?

Tracking LH (luteinizing hormone) levels during the first half of your cycle can help you detect an LH surge, which indicates you’ve reached your two most fertile days (also called “peak fertility”). This is the time to “try!” During the first half of your cycle — the “follicular phase” — your follicles mature in preparation for ovulation. When the time is right, your brain sends a surge of LH (luteinizing hormone) to trigger the mature follicle to release an egg. Ovulation typically occurs about 12-48 hours after an LH surge.

If I have an LH surge, can I be sure I ovulated as expected?

LH tests are often called “ovulation tests,” but contrary to their name, they do not confirm whether or not you’ve ovulated; they only detect the luteinizing hormone surge that typically precedes ovulation. Proov recommend using Proov Confirm PdG tests alongside your Predict tests so you can confirm whether or not ovulation was successful to allow for a higher possible chance at pregnancy.

Do I need to use first morning urine with Proov Predict?

No — you may use Proov Predict at any time of day. The Proov Insight app will prompt you to test two times per day during the LH testing phase. Many women find it convenient to test LH levels mid-morning and again later in the evening, but the choice is ultimately yours.

How long after a positive LH test are you fertile?

A positive LH test identifies your 2 most fertile days. However, since sperm can survive in the female reproductive tract for up to 5 days, you can actually be fertile for longer than 2 days. If you have been trying to conceive without success, Proov recommend trying Proov Complete to identify your full fertile window and maximise your chances at getting pregnant.

What level of LH predicts ovulation?

Clinical studies show that an LH level of 25 mIU/ml is best predictive of ovulation. This is the level at which Proov Predict LH tests turn positive!
