Micropenis: What are the Causes?

Micropenis: What are the Causes?

Micropenis refers to an abnormally small penis, in relation to the average size of a penis per age. Micropenis is a rare condition but can cause a great deal of emotional distress when it comes to sexual performance and appearance. Although the condition can feel challenging to overcome, there are treatment options available. Speaking to a qualified specialist can help an individual determine which treatment options may be best for them. 

What is a Micropenis?

When a micropenis is diagnosed it means that the penis, when stretched, is 2.5 standard deviations below the average. The average depends on the age of the individual. An individual at any age can be diagnosed with micropenis. For the average adult, doctors typically diagnose micropenis at 3.66 inches. Even when a person is diagnosed with micropenis, their testicles will be normal. 

What Causes Micropenis?

Micropenis typically presents itself at birth. The main cause of micropenis is hormonal imbalance. This could be due to a hormonal deficiency of testosterone during their mother’s pregnancy. The mother may have had low hCG, which would mean that the developing baby would have had difficulty producing testosterone

Interruptions in hormones during crucial times during pregnancy can result in a lack of penile development. Even if hormone production was normal, there could be other issues relating to the hormones, such as androgen sensitivity. This inhibits the body from properly responding to testosterone. 


Experiencing a medical disorder that affects hormone-production could also result in micropenis. These disorders may affect the pituitary gland or the hypothalamus. However, micropenis can also develop without any other conditions. 

How Does Micropenis Affect Sexual Function?

Sexual functioning is typically normal in individuals who have a micropenis. While micropenis does not affect the abilities of the penis directly when it comes to sexual function, it can have an emotional impact on an individual. A small penis may affect a person’s ability to urinate and they may experience difficulty urinating while standing up. A person may have increased anxiety about sexual performance. Performance anxiety can lead to avoidance of sexual encounters, a loss of desire, and confusion on sexual identity. Micropenis can also lead to feelings of inadequacy and insecurities regarding appearance. 

Micropenis Penile Implant 

There are treatment options for micropenis, including a micropenis penile implant. A micropenis penile implant can enhance girth and appearance. The Himplant by Dr. Elist is made of medical-grade silicone and is the only cleared male aesthetic-enhancement implant that can be found on the market. However, there are certain eligibility requirements that you must meet in order to safely have the procedure done. Implants are not typically offered as a first option but are offered after other methods have been utilized. 

A trained specialist can help determine if a micropenis penile implant is a right option for you and your sexual wellness.
