MedGen UID:

Disease or Syndrome
Familial male hypogonadism is a highly heterogeneous category from which some disorders such as Reifenstein syndrome (312300), Kallmann syndrome (see 308700), isolated gonadotropin deficiency, and some other entities can be separated. The presence of an autosomal recessive form is suggested by the occurrence of parental consanguinity (Nowakowski and Lenz, 1961).
