What is the prognosis (outlook) for patients with micropenis?

With early treatment the prognosis for boys with micropenis due to hormone deficiency is good. They usually respond well to testosterone therapy, gain adequate penile length (though below average size) and are able to function normally as adults.

The outlook is not as positive for those boys with micropenises that are due to other disorders, such as androgen insensitivity, who can’t be helped with hormone treatment. In these cases, the penis remains small.
