What Is Ovulation?

It is, basically, a process of rupturing of mature ovarian follicles as a result of which one or few eggs are discharged in the menstrual cycle of a female. The brain actually controls the process by releasing luteinizing hormone and follicle-stimulating hormone. If the sperm has fertilized the egg, it might implant 6-12 days later and that's the point when pregnancy starts.

Average time for ovulation tends to be 14 days prior to 1st day of the next period. But keep in mind that it is possible for the ovulation day to vary from woman to woman. So, only the cycle length may not be a very reliable indicator for the ovulation day. Ovulation tests tend to be more accurate and their accuracy rate is around 99%. Besides, you can buy them without even a prescription.

Usually, the ovulation test kits available measure LH level inside the urine of a woman. The surge of LH levels, also referred as "positive result", is actually an indicator of onset of the ovulation and fertilization windows that occur in following 3 days.
