In clinical terms, uterine regeneration refers to the process of returning the uterus from the state of pregnancy to the original non-pregnant state after childbirth or after induction of labor or abortion. This is a benign process, so clinically it can be done without treatment, as long as the recovery is observed to be good. After a normal delivery, the uterus will drop by about one finger per day, and it is normal if it reaches this standard. If the regeneration is not good, that is, the uterus is clinically soft and does not recover according to the normal recovery, clinical intervention should be given, such as intramuscular injection of oxytocin or oral new biochemical tablets, etc.
