The process of the egg and sperm coming together is called fertilization, which takes about 24 hours. The follicle ruptures, the egg is discharged from the ovary to the abdominal cavity, the umbilical end of the fallopian tube catches the egg and waits for the sperm to combine, the egg survival time is 24-48 hours, after coitus the male partner ejaculates sperm, the sperm is enabled to swim to the cervical canal in the vagina, the sperm releases proteolytic enzymes to dissolve the cervical mucus, swims from the uterine cavity into the fallopian tube, and combines with the egg in the tubal pudendal area. It takes 1-1.5 hours for the sperm to travel from the vagina to the juxtaposition of the fallopian tube. Then sperm through the release of acrosomal enzymes later into the oocyte’s zona pellucida fertilization process begins when the nuclei of the sperm and egg are fused together, marking the completion of the fertilization process, if the first ejaculation, follicle after discharge, sperm survival time of 24-72 hours.
