A practical approach to the assessment of the external genitalia in boys

Male infants and children are frequently referred with parental or health care provider concerns about small penis size. A micropenis is defined as stretched penile length less than 2.5 standard deviations of the mean for age. The term ‘inconspicuous penis’ has been used to describe a group of conditions that result in the penis appearing abnormally small. These conditions include: congenital megaprepuce, trapped penis (secondary to scarring following surgery, most commonly post circumcision), concealed penis (due to enlarged suprapubic fat pad) and webbed penis.
