Medical Definition of eunuchoidism
: a state suggestive of that of a eunuch in being marked by deficiency of sexual development, by persistence of prepubertal characteristics, and often by the presence of characteristics typical of the opposite sex.
What causes Eunuchoidism?
Gonadotropin (GnRH) deficiency
Kallmann syndrome (hypogonadotropin eunuchoidism) is the most frequent form of isolated gonadotropin deficiency – a rare X-linked recessive disease caused by a defect in a cell adhesion protein that participates in the migration of the GnRH neurons.
What are Eunuchoid proportions?
Usually the eunuchoid skeleton is defined by the finding of an abnormal upper to lower segment ratio (<0.88) and by the predominance of the arm span over the patient's height (ratio > 1) [40, 47, 70].
