The follicle is not expelled naturally but ruptures naturally before the egg is expelled. This means that after the follicle reaches dominance, due to the increase in local tension, the follicle wall gradually becomes thinner, it will rupture and expel the egg, which is a normal physiological phenomenon. This is a normal physiological phenomenon. Most women have a follicle that grows, develops and matures each month to discharge an egg, and if they have sex during ovulation, the sperm and the egg will unite to form a fertilized egg, which is what follicular rupture and discharge of an egg actually means in clinical practice. Most people ovulate 14 days before their next period, so it is recommended that women who plan to get pregnant calculate their ovulation time, calculate the ovulation period according to the ovulation time, and make reasonable arrangements for sex during the ovulation period, which will improve the chances of pregnancy.
