A pudendal nerve block is an injection of an anesthetic that works to block the pudendal nerve. This nerve goes into two branches, one on each side of your body, and carries sensation from your labia, clitoris, and perineum. Transvaginal refers to how this shot is administered, and it is given through your vagina. This procedure is done in the second stage of labor, just before your baby is born. This episode answers several questions relating to a pudendal nerve block, including whether it is recommended, short and long-term risks, and whether it will affect the progression of labor or your baby.
