Pudendal nerve
The
pudendal nerve
is the main
nerve
of the
perineum
. It carries sensation from the
external genitalia
of both sexes and the skin around the
anus
and perineum, as well the
motor
supply to various pelvic muscles, including the
male
or
female external urethral sphincter
and the
external anal sphincter
. If damaged, most commonly by childbirth, lesions may cause sensory loss or
fecal incontinence
. The nerve may also be temporarily blocked as part of an anaesthetic procedure.
