Follicular rupture is a normal physiological phenomenon that occurs during ovulation. Only after the follicle ruptures can the egg be released, which is affected by changes in estrogen and LH levels in the body. When a woman is not ovulating, if the follicles do not rupture, the eggs cannot be discharged, and even if she has sex at this time, she will not be able to get pregnant. Some women may experience soreness in the lower abdomen or a small amount of vaginal bleeding when the follicle ruptures during ovulation. After the egg is expelled, if the woman wants to get pregnant, she can arrange for intercourse during this period, the survival time of the egg is within 48 hours.
