Ovulation Predictor Kits
Ovulation predictor tests work by allowing you to detect your monthly LH Surge - the sudden and dramatic increase in luteinizing hormone present in your urine just before you ovulate. LH is the hormone that facilitates ovulation (the release of the egg). When you detect your LH surge with an ovulation test, you know you are fertile.
Since the best time for fertilization of the egg to occur is within 6 to 24 hours after you ovulate, correctly gauging your body's cycle is extremely helpful in increasing your chances of becoming pregnant.
