Kallmann syndrome

Kallmann syndrome is the combination of hypogonadotropic hypogonadism and anosia. 

It may be inherited in a X-linked recessive, autosomal dominant or autosomal recessive pattern. However, most cases are sporadic. 

Associations with the x-linked recessive form of Kallmanns include 
  • Unilateral renal aplasia - 30% 
  • Bimanual synkinesis (upper limb mirror movements) – 75% 

Blood LH/FSH/testosterone are all either normal or low. 

Treatment is with hormone replacment, which restores fertility in the vast majority of patients.
