Self-test for the detection of luteinizing hormone (LH) in urine. Ovulation is the term for the process that usually occurs between the 12th and 16th day of a regular 28-day menstrual cycle. During this process, hormonal changes activate the ovary to release a fertilizable egg. The closer you are to ovulation, the more the body produces an increasing amount of estrogen, which triggers a sudden increase in another hormone, called luteinizing hormone (LH), the peak of which causes the follicle to rupture and the consequent release of the mature egg, ready to be fertilized. Ovulation usually occurs between 24 and 36 hours after the LH surge. For this reason, monitoring LH levels in urine is a great indicator for predicting the time of maximum fertility for a woman.
