Ovulation Tests – or Ovulation Predictor Kits (OPKs) – Allow you to predict, with great accuracy, your most fertile time of the month. Easy to use, ovulation predictor kits can greatly increase your chances of becoming pregnant. To improve ovulation testing results, visit our Ovulation Test FAQ for testing tips.

Using Ovulation Tests to Predict Fertility
Ovulation is the defined as the separation of a mature ovum from the ovary after a follicle has been formed.For many women, ovulation takes place midcycle, around cycle day 14. Of course, irregular cycles and countless other factors can contribute to ovulation taking place either earlier or later. That’s why we use ovulation tests and chart fertility. In fact, “normal ovulation” can occur as early as day 8 or as late as three weeks into your cycle. When ovulation occurs is a coefficient of menstrual cycle length, so women with long cycles will ovulate later than women with shorter cycles.
Ovulation tests- or ovulation predictor kits (OPKs) – are excellent tools for predicting ovulation, a woman’s most fertile time during her menstrual cycle. Unlike BBT charting, ovulation tests anticipate ovulation – not just confirm that ovulation has taken place. Visit Early-Pregnancy-Tests.com to see a photo gallery of positive ovulation test results.
Ovulation tests work by detecting luteinizing hormone (LH). Just preceding ovulation, women experience an “LH surge” – a sudden, dramatic, and brief rise in the level of luteinizing hormone. Ovulation tests detect the LH surge, allowing you to accurately predict when you will ovulate. A positive result on an ovulation testmeans that the woman will most likely become fertile over the next three days – with peak fertility at 36 hours following the LH surge.
How do OPKs Work? Luteinizing Hormone and Ovulation
How do ovulation tests work? At the beginning of the menstrual cycle, the body begins to produce follicle stimulating hormone (FSH). FSH facilitates the formation of a follicle on one of the ovaries. The follicle contains and nurtures the egg. When a follicle has adequately matured, a surge of Luteinizing Hormone (LH) causes the follicle to burst and release the egg into the fallopian tube – the moment of ovulation.
