The ‘LH’ surge causes the release of the mature egg from the ovary – this is ovulation. Ovulation normally occurs 24 to 36 hours after the LH surge, which is why the LH surge is a good predictor of peak fertility. The egg can only be fertilized for up to 24 hours after ovulation.
How long after LH surge do you ovulate?
Ovulation is spontaneously triggered about 36-40 hours after blood levels of a hormone called luteinizing hormone (LH) rise. This is called the LH surge. Once released from the ovary, the egg is picked up by and travels down the fallopian tube where it can meet sperm to become fertilized.
Can you have an LH surge without ovulating?
