Normally the egg is discharged about 14 days before the next menstrual period, and ovulation usually occurs at some point during this phase, and its fertilization lasts for a long time, usually about 30 hours. It takes about 15 days for a woman’s ovaries to produce follicles that mature and ovulate. The follicles rupture due to hormones in the body and the surface tension of the ovaries, and the egg is then discharged at some point during this phase, which can usually be monitored by ultrasound under the guidance of a doctor. If a woman is ready to conceive, she can have intercourse at this stage to increase the chances of pregnancy by combining sperm and egg. If there is no need for conception, contraception should be used to avoid other problems.
