After the follicle ruptures, the egg is discharged, and the egg survives in the woman’s body for about 24 hours. The chances of conception are highest within 12 hours after the egg is discharged, and the quality of the egg will decrease after 12 hours, so the patient’s chances of conception will be relatively low. Therefore, it is recommended to have intercourse within 12 hours after the follicle has ruptured, and the earlier the intercourse, the better, so as to greatly improve the woman’s chances of conception. The survival time of the egg in a woman’s body is very short, but the sperm survival time in a woman’s body is relatively long, about 72 hours, so it is recommended that patients with pregnancy requirements try to choose to have intercourse before ovulation, so that after the egg is discharged, the egg can be conceived in the best quality of the egg, which greatly improves the chances of female conception.
