The ridged band is a band of highly innervated wrinkly skin just inside the tip of the foreskin. The term ridged is used to describe the area instead of the more commonly used term wrinkled. It has, especially in regard to phimosis (and preputioplasty), been called preputial ring or phimotic ring, ring being analogous to band, referring to the shape, and preputial meaning pertaining to the prepuce. More particularly, it refers to the transitional area from the external to the internal surface of the prepuce, or foreskin. The ridged band separates the outer skin of the penis from the inner mucosa. The ridged band contains nerve endings arranged at the crest of rete ridges. The nerve endings resemble Meissner corpuscles or Krause end-bulbs.

The nerve endings in the ridged band are stimulated by deformation of their capsules. Deformation of the capsules may occur by pressure, by stretching of the foreskin, or by the rolling or gliding of the foreskin during sexual activity.

The nerves of the ridged band are believed to provide sensory input to the autonomic nervous system, which regulates sexual response.

Because of its location, the ridged band is invariably excised if a male is circumcised.

The late John R. Taylor, MB, Ch.B.,MRCPEd, FRCPC, a British-Canadian pathologist and biomedical researcher who practiced in Winnipeg, MB, first used the term "ridged band" instead of "wrinkly skin" and described the ridged band at the Second International Symposium on Circumcision, organized by NOCIRC in San Francisco, 1991, after examining the foreskins of 22 adults obtained at autopsy. The mean age was 37 years, range 22–58. The prepuces were studied grossly and histologically.

Structure

Taylor described the ridged band as a transversely ridged band of mucosal tissue, located just inside the tip of the foreskin near the mucocutaneous boundary. He characterized the ridged band as intensely vascular and richly innervated, stating that it "contains more Meissner's corpuscles than does the smooth mucosa", and noted that these tactile corpuscles were found only in the crests of ridges.
