Penis Keratinization - Caused by Circumcision

Keratinization, also known as “cornification”, is a process of forming an epidermal barrier for the epithelial tissue due to increased production of keratin (fibrous structure proteins). This makes the outer layer of human skin much more tough and rigid.

Doctors and researchers from Childrens Hospital of Hangzhou have recently found that there is a lower incident of penis keratinization and higher density of Langerhans' cells in the outer foreskin than in the inner foreskin of both uncircumcised adults and healthy boys. ^[1] Unfortunately, circumcised boys and adults with a history of infection might be at a higher risk of developing keratinization. Many published research studies have tried to prove that there is no difference in keratinization for both circumcised and uncircumcised men. These studies used a very small group of males (less than 20), however, which might not be statistically sufficient. ^{[2] [3] [4]}

Neurological data from Dr. Immerman of Case Western Reserve University has suggested that early lesions from circumcision or injury to the foreskin would have induced brain circuitry atrophy or re-organization. Exposed forehead and penis Keratinzation caused by circumcision are major factors in lowering sexual excitability for men. ^[5]

More recent research has found that most surgeons performing circumcision have also removed the ridged band at the end of the foreskin. This ridged band is concentrated with Meissner’s corpuscles, the key nerve endings for sensitivity! Dr. Taylor suggested that the removal or injury of the ridged band would significant reduce the sexual stimulation from the gliding action of the penis during vaginal intercourse. Prominent ‘sexpert’ Dr. NK Lin has indicated that this is the key reason why some circumcised men are not able to achieve orgasm through normal vaginal intercourse, leaving them to often demand their partner perform oral stimulation. ^[6]
