What’s The Significance of the LH Surge?

When a couple decides it’s time to have a baby, figuring out the optimal time for intercourse can help speed up nature’s timeline. While lots of “practice” is a positive, there is a specific window of time each month when conception is possible.

The brain senses the elevated estrogen levels produced by the maturing egg and releases a burst of luteinizing hormone (LH). When the ovary is bombarded with this burst of LH, the sac-like covering (called the follicle) surrounding the egg thins, allowing the egg to escape.

For most women with regular cycles, the LH surge occurs between cycle day 12 and cycle day 16. Use of an ovulation predictor kit during this time period should yield a positive result. The ovulation urine or serum rapid test is a qualitative testing tool that can predict when there is a LH surge, and in turn decide when a woman is likely to ovulate. Detecting the LH surge is important because it allows accurate prediction of ovulation, thus improving the timing of fertility attempts.

On the day the kit returns a positive result, the couple can anticipate ovulation within 12-24 hours. Timing intercourse the day of the LH surge and the day after will ensure sperm exposure during this window of opportunity when egg fertilization is most likely.
