What is a micropenis?

Micropenis is a medical term used to describe an abnormally small penis. The most common criterion used to define a micropenis is a dorsal  erect penile length of at least 2.5 standard deviations smaller than the average human penis size. Confused?

In simple words, this means that any male adult with an erect penis of 9 cm (3.5 inches) or less should be evaluated for micropenis. For male newborns, the mean stretched penile length is around 3.5 cm and thus any baby with a stretched penile length of 2.0 cm or less, should also be evaluated for micropenis. It is estimated that around 1 in every 200 individuals has the condition (0,5 %).

Please note that there is no standard size for micro-penis, as it depends on factors like the individual's age and ethnicity.

For example, a study named "Should the definition of micropenis vary according to ethnicity?" concludes yes because "Mean penile length and diameter are slightly but significantly smaller in newborns of Chinese origin compared to newborns of Caucasian and East-Indian origins."

It should be mentioned that the micropenis term is typically used when the penis has a normal appearance with no other accompanying genital malformations, like hypospadias, epispadias, cryptorchidism etc. In the latter scenario, the term microphallus is preferred.

When and how can the condition be diagnosed ?
The condition is easily diagnosed at any age. A quick examination by a doctor or a physician will suffice. An individual can even perform a self-diagnosis, granted that he knows how to properly measure his penis.

However, several more tests may be required, as it common for the micropenis condition to be accompanied by other ailments as well. In most cases the condition is diagnosed right after birth.

What are the causes of micropenis ? 
The exact causes behind the condition have yet to be explored and understood in full extent. However, we do know that the condition is many times the result of several hormonal abnormalities (sex-chromosomes related) that occur during the second and third semester of pregnancy.

It is also possible for micropenis to be a part of other genetic malformation syndromes that are not related to the sex chromosomes. For example, it can be an early sign of congenital growth-hormone deficiency or congenital hypopituitarism.

Several homeobox genes have also been found to affect penis and digit size with no detectable hormone abnormalities.

Utero exposure to certain estrogen based fertility drugs like diethylstilbestrol (DES) has been linked to various genital abnormalities including the micropenis condition.

Finally, a 2012 study showed that domestic pesticide misuse increases the likelihood of newborns being born with a micropenis and/or other genital malformations.

Problems caused by micropenis
Some problems commonly reported by patients with the condition are:
  • Difficulty to urinate when standing
  • Difficulty to have sexual intercourse
  • Various psychological problems, varying from "minor" ones - like low self-esteem and difficulty talking to women- to more serious, like suicidal thoughts.

Conditions associated with the micropenis condition
Typically, the vast majority of conditions accompanying a micropenis are of reduced prenatal androgen production or effect. Some of these conditions are the following:
  • Testicular dysgenesis
  • Klinefelter syndrome
  • Leydig cell hypoplasia
  • Specific defects of testosterone
  • 17,20-lyase deficiency
  • 5α-reductase deficiency
  • Androgen insensitivity syndromes
  • Inadequate pituitary stimulation Gonadotropin deficiency Other forms of congenital hypogonadism.

Micropenis Treatments
Unfortunately, there is no easy and quick treatment for patients with the micropenis condition. Still, there are many clinically tried methods to enlarge a micropenis. However, these methods greatly vary and depend on the patient's age and the severity of the condition (how small the penis is).

Treatments for adults
As of now there are two clinically proven ways to enlarge an adult's penis and thus a micropenis. Click the corresponding links, to read more for each option:
  • Using a penis traction device: A 2006 study has showed that penis enlargement using a traction device is possible. However, this is an option for border-line micropenises (3.0 inches when erect or larger). This is the method I used to enlarge my penis from 5.0 inches to 5.8
  • Phalloplasty: Phalloplasty is a type of surgery that among others, is also used for penis enlargement. There have been been many successful examples, some of which are featured in the studies section of the site
  • Human Chorionic Gonadotropin, may have possible future applications for the treatment of adults. However this hormone treatment is still experimental, having been tried only once in human patients.

Treatments for children with micropenis
Hormone treatment (containing testosterone) has shown very promising results in the treatment of micropenis, especially when given at a very young age.

Alternative Micropenis Treatment Options
In the past, many doctors opted newborns with a micropenis for a sex reassignment operation. During the past years this approach has been abandoned for a variety of reasons, mainly the ones explained here.
