Something you didn't learn in health class (and doctors don't learn in med school)

It would seem that male Homo sapiens are blessed with something unique in the mammalian realm, as explained in this video interview.

"Ken McGrath, Senior Lecturer in Pathology at the Faculty of Health, Auckland University of Technology and Member of the New Zealand Institute of Medical Laboratory Scientists discusses his research into the neural anatomy of the human penis and the physical damages caused by circumcision.

McGrath is author of The Frenular Delta: A New Preputial Structure published in Understanding Circumcision: A Multi-Disciplinary Approach to a Multi-Dimensional Problem, Proceedings of the Sixth International Symposium on Genital Integrity: Safeguarding Fundamental Human Rights in the 21st Century, held December 7-9, 2000, in Sydney Australia.

Abstract: Textbooks and papers referring to penile function state that the source of penile sensation is solely the glans and often justify the existence of the prepuce by stating it protects the 'sensitive' glans. These statements are contrary to the neuro-anatomical and physiological facts accumulated over more than a century. This study reviews the findings of Taylor, et al., that the prepuce is the primary sensory platform of the penis, and describes a new preputial structure.

This interview was taped in Berkeley, California 2010."
