Infertility after cesarean section may be due to the manipulation of surgical instruments on the uterus or postoperative puerperal infection, leading to pelvic inflammation and fallopian tube blockage, resulting in infertility.

Therefore, it is crucial to pay attention to hygiene during the puerperium after a cesarean section, monitor the recovery of the uterus and the lochia, and observe the color and odor of the lochia daily. If the uterus does not recover well, and the lochia is excessive or persists for a long time, it is important to seek medical advice early. If there is a foul odor, timely treatment is necessary to avoid chronic pelvic inflammatory disease. It is also essential to get out of bed and move around timely to prevent the formation of venous thrombosis.
