Ovulation is the process which occurs in female bodies every month. In this process, an egg is released from the ovary. Every month hormonal changes occurring during menstrual cycle causes one egg to mature and release from the follicle/ovary. During the time of ovulation, your body produces increased amount of hormone called estrogen which triggers further the release of another hormone called luteinising hormone. This luteinizing hormone is the cause of release of an egg from the ovary the release of the egg takes place 24 to 36 hours after the luteinizing hormone level reaches peak point. That is why fertility is best predicted by luteinizing hormone level around the time of ovulation.

Every month egg is released from one of the ovaries make its way to the uterus through the fallopian tube. It is the time when an egg can be fertilized by the sperm. But this egg can survive only for 12-24 hours while a sperm can live in the female body for up to 5 days. This time is of importance to those couples who want a baby. The fertility windows range from 6-8 days including days of ovulation. Ovulation occurs on 14th day of your menstrual cycle if you have regular cycles of 28 days.
