In obstetrics there is a common but particularly controversial procedure called an episiotomy.
Episotomy is the surgical lengthening of the vaginal orifice through an incision in the perineum, made during labor with the aid of a scalpel or scissors and which requires suturing.
The practice is indicated when there are difficulties with the delivery of the baby, in natural childbirth, and the first report of application of the practice dates from 1741.
An episotomy takes about 6 weeks to heal, during which se*xual intercourse is impossible.
