Kallmann syndrome is a rare genetic hormonal condition that is characterized by a failure to start or a failure to complete puberty. It is also accompanied by a lack of sense of smell (anosmia) or a highly reduced sense of smell (hyposmia). The condition can occur in both males and females but is more commonly diagnosed in males. Left untreated, patients with Kallmann syndrome will almost invariably be infertile.
Kallmann syndrome is a form of hypogonadotropic hypogonadism (HH).
