How long after giving birth is it recommended to wear a tubal ligation?

Patient's question:

During pregnancy, it's always particularly uncomfortable, and morning sickness is also very severe. How long after giving birth is it recommended to wear a IUD?

Doctor's answer:

Hello
For normal delivery, the intrauterine device (IUD) should be inserted three months after childbirth, while for cesarean section, it should be inserted six months later. The IUD can be inserted three to seven days after the menstrual period ends, but sexual activity should be avoided before insertion.
For women who have undergone normal delivery, the uterine body typically returns to its normal size around 42 days postpartum. The endometrium, however, takes about 56 days to fully heal. The vaginal mucosa must wait until the ovarian function returns to normal, i.e., after the menstrual period, to fully recover.
Therefore, sexual activity must be strictly prohibited within 56 days postpartum.
