The most common cause of this is testicular feminization (androgen insensitivity) syndrome, which results from end-androgen resistance and leads to a small testis and a rudimentary vagina (persistent genitourinary sinus) without fallopian tubes or a uterus. If a girl with a hernia has testicular feminization, a gonadectomy on one side and isolation of the other gonad in a superficial position until puberty permits secondary sexual characteristics to develop. Hermaphrodites have an asymmetric ovotestis, which should not be removed.
