Ways to shrink your vagina after childbirth. The vagina itself has a certain repair function and the dilatation that occurs after childbirth can be recovered in 3 months after giving birth. However, after all, after squeezing and tearing, the muscles in the vagina are damaged, so it takes longer for the vaginal elasticity to recover. Postpartum mothers can strengthen the elasticity by holding the urine, lifting the anus and contraction exercises to promote vaginal tightness, but this method needs long-term persistence. For women who have very serious laxity, they can have a vaginal reduction surgery. Surgery on the private parts of the woman is generally indicated for patients with serious conditions for which conservative treatment is not effective.
