The bulbocavernosus reflex has been found to be delayed or absent at a higher rate than the general population of [[intact]] men in diabetic men with complaints of erectile impotence, men whose penises have been circumcised, and in intact men who have permanent retraction of the [[foreskin]] behind the [[glans penis]].<ref name="podnar2012" />
Podnar cited previous research in explaining his findings. Among other works, Taylor et al. (1996) carried out a histological study of the [[foreskin ]] which found large numbers of [[Meissner's corpuscles]] arranged in a [[ridged band]].<ref name="taylor1996">{{TaylorJR LockwoodAP TaylorAJ 1996}}</ref> and Sorrells et al. (2007) carried out a study of the fine-touch pressure thresholds on the human penis and found that the most sensitive areas are all on the foreskin.<ref name="sorrells2007">{{Sorrells etal 2007}}</ref>
Men who have suffered the loss of their foreskin to [[amputation]] and men whose foreskin has been desensitized by permanent retraction evidently are unable to sense the stimulation necessary to trigger the penilo-cavernosus reflex..<ref name="podnar2012" />

Podnar's study highlights the importance of the sensory input from the nerves of the [[foreskin ]] in the regulation of physiological functions through the autonomic nervous system.
