Ovulation is the process in which an ovary releases an egg. It is part of the female reproductive cycle and is necessary for reproduction. During this process, the ovary releases a mature egg that travels down the fallopian tubes and into the uterus. If the egg is fertilized by a sperm, the egg will attach to the uterine lining and develop into an embryo. If the egg is not fertilized, it will pass through the uterus and be expelled from the body during menstruation. Ovulation typically occurs around day 14 of a 28-day menstrual cycle, although the exact timing may vary from woman to woman. Signs of ovulation include an increase in cervical mucus, a rise in body temperature, and changes in the cervix. Ovulation can be tracked by measuring body temperature, using an ovulation predictor kit, or monitoring changes in cervical mucus. Women who are trying to conceive should be aware of the signs of ovulation and should time intercourse around the time of ovulation. This increases the chances of fertilization and pregnancy. Women who are not trying to conceive should take precautions to prevent pregnancy during ovulation. This can include using barrier methods of contraception such as condoms or using hormonal methods such as the pill.
