The use of ovulation strips allows to predict when ovulation will occur to be able to have sex for the purpose of conceiving. The ovulation test detects the peak production of the hormone LH (luteinizing hormone), which is responsible for the expulsion of the ovum by the ovarian follicle, the process defined as ovulation.
Ovulation occurs between 12-24 hours after LH peak, therefore, there are between 36 to 48 working hours to have sex since the test is positive i.e. since the test detects high production of LH. By determining the peak of production, the ovulation test allows to concentrate the sexual relations in the most fertile days.
The ovulation test will be done every day at the same time. The elevation of LH levels usually starts early in the morning but needs 4 to 6 hours before it can be detected in the urine on which the test is based. That is why it is advisable to carry out the ovulation test after the meal.
