Ovulation is the process by which the mature egg leaves the ovary, or an egg is released from the ovary,


The ovary contains a huge number of follicles, each follicle contains cells with immature eggs the first seven days the Immature egg starts to degenerate leaving a single dominant follicle to grow,

The follicle-stimulating hormone(FSH) nourishes and helps the egg to mature  in preparation for the release of the egg during ovulation, The developing follicle secret estrogen(sex hormone)  which then increases, the sex-hormone also secret corpus lutem to prepare the uterus  in the regeneration of the endometrial lining to prepare the uterus for pregnancy

Fertilization occurs in the fallopian tube the egg travels to the fallopian tube so it can be fertilized, the egg stays for 24hours so it can be fertilized by the sperm, the sperm can live for 5days, but If fertilization does not occur during that period,  the  corpus lutem result in the fall of the sex hormone (estrogen and progesterone) shielding the uterine lining starting the next menstrual period
