Ovulation and fertilization

Ovulation is the release of one or more eggs from a follicle that developed in the ovary. The egg travels to a fallopian tube where it is typically fertilized. Ovulation is brought about by a series of events within the hypo-pit-ovarian axis. Day 1 of menstrual bleeding is the first day of the cycle. The time interval from day 1 to ovulation may vary from woman to woman and from one cycle to another. The time interval from ovulation until menstruation is about 2 weeks. Ovulation will occur early in a short cycle and later in a long cycle. Observing the cervical mucus symptom gives information about being potentially fertile or infertile on a day by day basis.
