Doctor's answer:

Generally, married women who have given birth are afraid of vaginal relaxation, as it can significantly reduce the quality of sexual life for couples. Therefore, some women choose to have a cesarean section during childbirth, which is also a major factor in this issue.
What is vaginal relaxation? In reality, vaginal relaxation refers to the vaginal wall tissues or pelvic supportive ligaments and membranes that cannot maintain their original tight structure due to certain reasons, similar to the sagging of elderly eye bags or relaxed forehead skin. The main causes of vaginal wall relaxation include congenital structural looseness, muscle elasticity weakening after female miscarriage or childbirth due to vaginal expansion, and long-term chronic abdominal pressure leading to prolapse, such as prolonged heavy lifting or chronic coughing.
