So What Is It Exactly

It is the period when a mature egg is released from its follicle and journeys down the fallopian tube, with the hope of getting fertilized. This usually happens about midway through the menstrual cycle, right after the follicular phase. So, especially taking into consideration the lifespan of sperm, the days leading to, and following, ovulation are considered the most fertile, typically days 10 to 18 of a regular 28 day cycle.
