Pediatric Micropenis

Key Points About Micropenis in Children

  • A micropenis is a penis that is smaller than normal. A penis length of less than 0.75 inches for a newborn boy is considered micropenis.
  • It can happen on its own. But it often happens along with other disorders.
  • It can occur with a hormone disorder that causes an abnormal level of the hormones involved in the growth of the sexual organs. This can include problems with the pituitary gland or the hypothalamus.
  • Hormone therapy may be used to treat some children. This can help to cause penile growth. Sometimes surgery may be an option.
  • In some cases, a man with micropenis may have low sperm count. This can result in infertility or decreased fertility.
