What can the LHs level tell about the ovulation?
Ovulation is the release of an egg from the ovary. The egg passes into the fallopian tube where it is ready to be fertilized. In order for pregnancy to occur, the egg must be fertilized by sperm within 24 hours after its release. Immediately prior to ovulation, the body produces a large amount of luteinizing hormone (LH). This is known as the LH surge and usually takes place in the middle of the menstrual cycle. LH triggers the release of an egg from the ovary.
