Inadequate gonadal function, as manifested by deficiencies in gametogenesis and/or the secretion of gonadal hormones; results in atrophy or deficient development of secondary sexual characteristics and, when occurring in prepubertal males, in altered body habitus characterized by a short trunk and long limbs.
- familial hypogonadotropic h. [MIM*312100 & MIM*307300] a group of disorders characterized by failure of sexual development, owing to inadequate secretion of pituitary gonadotropins; perhaps X-linked, but probably autosomal dominant and recessive modes of inheritance also exist.
- hypergonadotropic h. defective gonadal development or function of the gonads, resulting from elevated levels of gonadotropins.
- hypogonadotropic h. defective gonadal development or function, or both, resulting from inadequate secretion of pituitary gonadotropins. SYN: hypogonadotropic eunuchoidism, secondary h..
- male h. SYN: eunuchoidism.
- primary h. defective gonadal development or function, or both, due to abnormality or loss of the gonad itself.
- secondary h. SYN: hypogonadotropic h..
- h. with anosmia failure of sexual development secondary to inadequate secretion of pituitary gonadotrophins, associated with anosmia due to agenesis of the olfactory lobes of the brain. Autosomal dominant [MIM*147950], autosomal recessive [MIM*244200], and X-linked recessive [MIM*308700] forms exist; the X-linked form is caused by mutation in the Kallmann gene (KAL1) on Xp. SYN: Kallmann syndrome.
