It helps determine the time in the menstrual cycle when getting pregnant is most likely.The test detects a rise in luteinizing hormone (LH) in the urine. A rise in this hormone signals the ovary to release the egg. This at-home test is often used by women to help predict when an egg release is likely. This is when pregnancy is most likely to occur. These kits can be bought at most drug stores.LH urine tests are not the same as at home fertility monitors. Fertility monitors are digital handheld devices. They predict ovulation based on electrolyte levels in saliva, LH levels in urine, or your basal body temperature. These devices can store ovulation information for several menstrual cycles. How the Test is Performed Ovulation prediction test kits most often come with five to seven sticks. You may need to test for several days to detect a surge in LH. The specific time of month that you start testing depends on the length of your menstrual cycle. For example, if your normal cycle is 28 days, you'll need to begin testing on day 11 (That is, the 11th day after you started your period.). If you have a different cycle interval than 28 days, talk to your health care provider about the timing of the test. In general, you should begin testing 3 to 5 days prior to the expected date of ovulation.You will need to urinate on the test stick, or place the stick into urine that has been collected into a sterile container. The test stick will turn a certain color or display a positive sign if a surge is detected. A positive result means you should ovulate in the next 24 to 36 hours, but this may not be the case for all women. The booklet that is included in the kit will tell you how to read the results.You may miss your surge if you miss a day of testing. You may also not be able to detect a surge if you have an irregular menstrual cycle. How to Prepare for the Test DO NOT drink large amounts of fluids before using the test.Drugs that can decrease LH levels include estrogens, progesterone, and testosterone. Estrogens and progesterone may be found in birth control pills and hormone replacement therapy.The drug clomiphene citrate (Clomid) can increase LH levels. This drug is used to help trigger ovulation. How the Test will Feel The test involves normal urination. There is no pain or discomfort. Why the Test is Performed This test is most often done to determine when a woman will ovulate to assist in difficulty in getting pregnant. For women with a 28-day menstrual cycle, this release normally occurs between days 11 and 14.Difficulty in getting pregnantInfertility means you cannot get pregnant (conceive).

Normal Results A positive result indicates an "LH surge." This is a sign that ovulation may soon occur. Risks Rarely, false positive results can occur. This means the test kit may falsely predict ovulation. Considerations Talk to your provider if you are unable to detect a surge or do not become pregnant after using the kit for several months. You may need to see an infertility specialist.Open ReferencesReferencesJeelani R, Bluth MH. Reproductive function and pregnancy. In: McPherson RA, Pincus MR, eds.

FSH and LH in turn control the release of sex hormones (testosterone, estrogen, and progesterone). In children, these hormones govern the onset of puberty and sexual development. After puberty and during adulthood, they control reproductive function.GonadotropinsillustrationGonadotropins - illustration The pituitary gland controls the release of several hormones, including the gonadotropins FSH (follicle-stimulating hormone) and LH (luteinizing hormone).
