In clinical practice, doctors judge poor uterine regeneration after delivery mainly by touching the texture of the uterus. If the uterus is soft, the doctor considers that the uterus is poorly regenerated, while if the uterus is well regenerated the uterus is hard. Also if the uterus is bleeding heavily, or if there is repeated vaginal bleeding, i.e., dripping. The common reasons are postpartum fatigue, placenta residue, and fibroids on the uterus, which can affect the contraction of the uterus and cause poor uterine regeneration after delivery.
