The complications of untreated hypogonadism differ depending on what age it first develops — during fetal development, puberty or adulthood.

Fetal development

A baby may be born with:

  • Ambiguous genitalia
  • Abnormal genitalia


Pubertal development can be delayed or incomplete, resulting in:

  • Diminished or lack of beard and body hair
  • Impaired penis and testicle growth
  • Unproportional growth, usually increased length, of arms and legs compared with the trunk
  • Enlarged male breasts (gynecomastia)


Complications may include:

  • Infertility
  • Erectile dysfunction
  • Decreased sex drive
  • Fatigue
  • Muscle loss or weakness
  • Enlarged male breasts (gynecomastia)
  • Decreased beard and body hair growth
  • Osteoporosis
