Micropenis is a condition when the penis is smaller than normal. This condition can usually be detected since infancy or children. Even so, micropenis is classified as very rare, it only occurs in 0.6 percent of men in the world

Men with micropenis still have a normal penis shape and appearance. So, the difference is only in size. However, micropenis is sometimes also associated with lower sperm counts, so fertility rates may be lower.

Signs of a Micropenis

To diagnose micropenis, the penis is measured when it is not erect or tense. When measured, the penis must be pulled forward and the length is calculated from the base of the shaft of the penis to the tip.

Here are the criteria for micropenis by age:

  • Mature men: penis length less than 9.3 cm
  • Children: penis length less than 3.8 cm
  • Newborn: penis length less than 1.9 cm

Various Causes of Micropenis

Micropenis can occur alone or in conjunction with other disorders. Here are some causes of micropenis:

hormone disorders

Hormonal disorders are the main factors that cause micropenis. When in the womb, the baby's body with micropenis does not produce enough androgen hormones, especially testosterone.Alternatively, the baby may produce this hormone, but may not respond normally to it.

Hormonal disorders that occur in patients with micropenis are generally caused by secondary hypogonadism or hypogonadotropic hypogonadism (HH). In this condition, the hypothalamus gland in the brain cannot secrete enough hormones that function to produce androgen hormones.

Exposure to hazardous substances

Studies reveal that exposure of the fetus to harmful substances, such as pesticides and other chemicals, can be the cause of micropenis and other congenital abnormalities.

In addition to those mentioned above, micropenis can also occur due to heredity. Not only that, micropenis generally can also occur together with other abnormalities due to chromosomal abnormalities, such as androgen insensitivity syndrome (AIS), Klinefelter syndrome, Turner syndrome, and Down syndrome.

How to Overcome a Micropenis

The treatment of micropenis in children is different from that of adults. Here is a complete explanation that you need to know in dealing with micropenis:

hormone therapy

Basically, micropenis will be easier if treated early. Considering that the genitals of infants and toddlers are still developing, treatment with hormone therapy is considered to have a significant effect in supporting penis growth.

This therapy is done to stimulate normal penis growth. During hormone therapy, the baby or child will be given an injection of testosterone or a gel/ointment containing testosterone which is directly applied to the genitals.

This therapy is most effective when used on children under 3 years old, but can still benefit boys under 8 years old.


Phalloplasty is a surgical procedure that is more often performed on male teenagers or adults. Phalloplasty is performed to modify the micropenis to a normal size.

However, it should also be understood that sometimes phalloplasty has some risks of side effects, such as erectile dysfunction and disorders of the bladder tract.

Having a micropenis often makes adult men feel anxious and lose confidence, especially when they are having sex with their partner. In this case, it may take the help of a psychologist to provide counseling about how a person sees himself.

Meanwhile, to correct the problem of penis size, adult men are advised to consult a urologist. For parents who suspect that their child has a micropenis, you should check with a pediatrician so that the cause can be identified and appropriate treatment given.
