Ovulation is the release of an egg from the ovary. It usually occurs about midway through a woman’s menstrual cycle. After ovulation, the egg is available to be fertilized by a sperm for about 12 to 24 hours. If fertilization does not occur, the egg is absorbed into the lining of the uterus and the woman’s menstrual period begins.
To calculate the most likely days of ovulation, enter the first day of your last menstrual period and the average length of your menstrual cycle into the ovulation calculator. The ovulation calculator will then give you a range of dates on which you are likely to ovulate. You can use this information to plan your sexual activity accordingly.
