Anosmia, the inability to smell, was first described with hypogonadotropic hypogonadism in 1856, but it was not until 1944 that an instance of Kallman's reported the inheritance of the two symptoms together in three separate families.
Kallman's syndrome is a disorder of hypogonadotropic hypogonadism, delayed puberty, and anosmia (the inability to smell).
The most common features are HH and anosmia, though a wide range of features can present in an affected person.
Hence, the syndrome of hypogonadotropic hypogonadism and anosmia was named Kallman's syndrome (KS).
