Ovulation – the most fertile time during your menstrual cycle – is the moment a mature egg is released from the ovary. Once released, the egg has a life span of about 24 hours. Conception is most likely to take place at this time – so precise ovulation prediction is key. “Peak fertility” is considered to be the day before and the day of ovulation. As the egg can survive about 24 hours, conception must take place within this window.
