Most people with 17-beta are born with a vulva and vagina, and their testes are most often undescended. Some people with 17-beta will be born with genitals that do not clearly resemble a typical penis or a typical vulva. Some will have a penis that may be smaller than typical (known as a micropenis), and the urethra may open on the underside of the penis rather than at the tip (known as hypospadias). In adolescence, people with 17-beta will often develop some secondary sex characteristics associated with a typical testosterone puberty.
