ParaphimosisParaphimosis is an uncommon medical condition in which the foreskin of a penis becomes trapped behind the glans penis, and cannot be reduced (pulled back to its normal flaccid position covering the glans). If this condition persists for several hours or there is any sign of a lack of blood flow, paraphimosis should be treated as a medical emergency, as it can result in gangrene. Paraphimosis is usually caused by medical professionals (iatrogenic) or parents who handle the foreskin improperly.
ForeskinIn male human anatomy, the foreskin, also known as the prepuce (ˈpriːpjuːs), is the double-layered fold of skin, mucosal and muscular tissue at the distal end of the human penis that covers the glans and the urinary meatus. The foreskin is attached to the glans by an elastic band of tissue, known as the frenulum. The outer skin of the foreskin meets with the inner preputial mucosa at the area of the mucocutaneous junction. The foreskin is mobile, fairly stretchable and sustains the glans in a moist environment.
BalanitisBalanitis is inflammation of the glans penis. When the foreskin is also affected, the proper term is balanoposthitis. Balanitis on boys still in diapers must be distinguished from redness caused by ammoniacal dermatitis. The word balanitis is from the Greek βάλανος balanos, literally meaning 'acorn', used because of the similarity in shape to the glans penis.
PhimosisPhimosis (from Greek φίμωσις phimōsis 'muzzling') is a condition in which the foreskin of the penis cannot stretch to allow it to be pulled back past the glans. A balloon-like swelling under the foreskin may occur with urination. In teenagers and adults, it may result in pain during an erection, but is otherwise not painful. Those affected are at greater risk of inflammation of the glans, known as balanitis, and other complications. In young boys, it is normal not to be able to pull back the foreskin at all.
CircumcisionCircumcision is a procedure that removes the foreskin from the human penis. In the most common form of the operation, the foreskin is extended with forceps, then a circumcision device may be placed, after which the foreskin is excised. Topical or locally injected anesthesia is generally used to reduce pain and physiologic stress. Circumcision is generally electively performed, most commonly done as a form of preventive healthcare, as a religious obligation, or as a cultural practice.
