In a new study, women considered the position and shape of the urethral opening to be the least important aspects of a penis' appearance.

They also perceived the genitals of men who underwent surgery to treat distal hypospadias--a congenital condition in which the opening of the urethra is on the underside of the penis--to be as normal-looking as nonaffected, circumcised genitals.

"The information may help prevent the development of shame or impaired genital perceptions about penile appearance," said Dr. Norma Ruppen, lead author of the study.
