Labiaplasty and Childbirth - is it best to wait until after I've had my final child before getting surgery?

It is always best to wait until after the last "vulva modification" before you have a procedure to correct it. You also need to keep in mind that certain laxities and other changes can persist for up to 3 months after delivery. So, be sure to wait long enough.

It is advisable to avoid having a vaginal birth following a vaginoplasty; however, a labiaplsty is exempt from this rule. Your vaginal opening's look and shape may change after giving birth, but your labia won't change much or increase following a vaginal delivery.

Thank you for your question about Labiaplasty before having your next child.
Although performing labiaplasty should not have any effect on your future natural childbirth, common sense says to wait till you are done having children, in case of any trauma/ Tear in labia minora or if you find out you want to include perineoplasty or other vaginal repairs.

In case for personal or medical reasons you feel having labiaplasty earlier is important for you, as other doctors have mentioned here, doing it should be safe.
Good luck and best of health
