Buried penis, also called hidden penis or retractile penis, is a congenital or acquired condition in which the penis is partially or completely hidden below the surface of the skin. A buried penis can lead to urinary difficulties, poor hygiene, infection, and inhibition of normal sexual function. Buried penis is different from micropenis, which is an abnormally small, normally structured penis with a stretched penile length of less than 2.5 standard deviations below the mean for age or stage of sexual development of the patient. .
