Additional symptoms that can be sometimes associated with Kallmann syndrome and congenital hypogonadotropic hypogonadism:

  1. Anosmia (no sense of smell or vastly reduced sense of smell)
  2. Hearing difficulties
  3. Cleft lip / palate
  4. Mirror movements of the hands
  5. Absence of one a kidney
  6. Undescended testes (either one or both)
  7. Micropenis
  8. Scoliosis (abnormal curvature of the spine)
  9. Dental agenesis (missing teeth)
  10. Osteoporosis (fragile / brittle bones due to low bone mineral density)

There are additional symptoms that sometimes can be associated with cases of Kallmann syndrome or CHH. Whether or not these symptoms are present will depend on the precise genetic cause of each individual case. Also the degree of severity of the symptoms can vary markedly even within siblings.
