Ovulation is the central event in the menstrual cycle . Since the egg remains alive for only 24 hours, being able to pinpoint when ovulation occurs ( "the fertile time" ) is critically important for infertile couples.

Ovulation prediction test kits (OPK) are a very useful scientific tool for helping women to pinpoint ovulation. You can now buy them from us from our online store.  These kits detect LH which is produced in large quantities shortly before ovulation and can be found in the urine . Once the LH surge has occurred, ovulation usually takes place within 12 to 44 hours. Urine testing is started about two days prior to the expected day of ovulation and continues until the test becomes positive. The urine should be collected at the same time every day - and testing the first morning urine sample is a good idea.

If your menstrual cycles are irregular, testing should be timed according to the earliest and latest possible dates of ovulation. For example, if your cycle ranges between 27 and 34 days, you could possibly ovulate between days 13 and 20. Therefore, testing should begin on day 11 and continue until ovulation is indicated or through day 20. There is an 80 percent chance of detecting ovulation with five days of testing and a 95 percent chance with ten days of testing. Occasionally, ovulation may not occur in a particular cycle. If the ovulation prediction test has been timed and performed accurately and has not turned positive, you should discontinue testing and begin again with your next menstrual cycle. Persistent failure of the test to turn positive may indicate a problem with regard to ovulation.

Once a test has registered positive, indicating that ovulation is about to take place, it is no longer necessary to continue testing. Remaining tests in a kit may be saved and used in the following menstrual cycle if pregnancy does not occur.

Ovulation prediction kits offer the advantage that they allow you to predict when ovulation will occur - thus maximising the chances that intercourse will be timed at your most fertile period. They can also be done in the privacy of your own home.

The Home Ovulation Test can help you plan baby making sex with your partner during your peak fertile time , in order to maximise your chances of conceiving. In each cycle, the level of luteinizing hormone (LH) surges , causing ovulation to occur 24-36 hours later. The Test kit allows you to detect this LH surge in your urine, and therefore tells you the 2 days when you have the best chance of conceiving. The Ovulation Test is:
