Frenulum labiorum pudendi
The area where the labia minora meet posteriorly is called the posterior commissure of the labia minora.
The fourchette may be torn during delivery due to the sudden stretching of the vulval orifice. To prevent this tearing in a haphazard manner, obstetricians and, less frequently, midwives may perform an episiotomy, which is a deliberate cut made in the perineum starting from the fourchette downwards. Episiotomies may result in reduced sexual sensation following recovery as the fourchette is a part of the clitoris and contains sensory nerve endings which are severed in the procedure.
