B is for Bulbocavernosus Reflex

The bulbocavernosus reflex (BCR) is useful in testing spinal cord injuries.  The BCR test involves squeezing the glans penis or the clitoris and monitoring the reflexive contractions of the anal sphincter.

The BCR is found to be absent in over 70% of circumcised men.
