The birth canal to the space that provides a pathway for the birth foetus. It is made up of the following elements: the uterine corpus, the uterine isthmus, the cervical canal and the vagina. During childbirth, the birth canal is exposed to various types of damage (perineal rupture, need for a perineal incision), which are painful for the woman giving birth. It is therefore possible to use a special gel that creates a slip layer in the birth canal.
