Atypical Genitalia

Most resources conflate atypical and ambiguous genitalia. Atypical genitalia are probably best described as genitals that are different from what is normally expected at birth, but they may be unambiguously male or female in appearance. Examples include labial hypertrophy or “winged labia”; a hydrocele (a fluid-filled sac in the scrotum) that appears at first glance like a third testis; and an extended foreskin that appears “droopy,” covers the penis, and extends well beyond the penis when it is flaccid. Genitals may also be absent, but this is very rare.
