Included titles and symbols : Hypogonadism and testicular atrophy;
Description : See 307300 for a discussion of X-linked forms of male hypogonadism. 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).;
