Which description best characterizes penile skin?

Which description best characterizes penile skin?

• A. Thick and hair-bearing along the shaft
• B. Opaque and uniformly colored
• C. Thin and darkly pigmented at the neck of the glans
• D. Wrinkled and pale at the base

Answer: (C)

Penile skin isn’t uniform; it changes from shaft to glans. The skin over the shaft is keratinized and can be hair-bearing, giving a relatively rugged, outer-skin appearance. By the coronal sulcus, where the glans begins, the skin becomes thinner and often darker due to higher pigment density and easier visibility of underlying vessels. This thin, pigmented transition zone at the neck of the glans is the best description because it captures both the epithelium’s reduced thickness and the characteristic darker coloration seen there, distinguishing it from the thicker, hair-bearing shaft skin or the nonkeratinized mucosal surface of the glans itself.
