What Causes Blackening of the Glans Penis?

Darkening of the glans penis may result from either physiological or pathological causes. 1. Physiological cause: After male puberty, increased testosterone levels can lead to melanin deposition in the genital organs, causing darkening of the glans. This darkening may gradually intensify with age. 2. Pathological causes: Conditions such as balanitis or posthitis may cause black spots or generalized darkening of the glans. Additionally, prolonged irritation from topical medications used during treatment may also contribute to glans discoloration. If sudden darkening of the glans occurs, prompt medical evaluation at a hospital is recommended.
