This nerve originates from the Onuf nucleus (S2, 3, 4), and forms part of the somatic peripheral nervous system primarily responsible for the sensation from the genitalia and the contraction of bulbocavernosus and ischiocavernosus muscles necessary for a rigid erection.
DESIGN: The Hershberger bioassay is designed to identify suspected androgens and antiandrogens based on changes in the weights of five androgen-responsive tissues (ventral prostate, paired seminal vesicles and coagulating glands, the levator ani and bulbocavernosus muscles, the glans penis, and paired Cowper's or bulbourethral glands).
For example, some groups defined the end of spinal shock as the first few days postinjury when recovery of initial reflexes, such as the bulbocavernosus reflex, had occurred, other groups as 2 weeks postinjury when recovery of the deep tendon reflexes had occurred, while still other groups defined the end of spinal shock as ~2 months postinjury when recovery of the bladder reflex had occurred.
