The structure of the vagina is the same for those who have had children and those who haven’t, although there may be a difference in the tightness of the vaginal muscles. Generally, the structure of the vagina does not change depending on whether or not there has been a birth, so structurally speaking, the structure of the vagina is the same for those who have and those who have not had children. However, in women with a history of pregnancy and childbirth, especially those who have given birth naturally, the vaginal muscles loosen during labor, facilitating the delivery of the fetus. After natural delivery, the loose vaginal muscles will gradually recover, but whether they can recover as before varies from person to person. Women are advised not to worry too much, pay attention to cleanliness and hygiene, and go to a regular hospital if they have any discomfort.
