Where urologists go for ED care

Definition: What is a Micropenis?

A micropenis or microphallus is a functional penis that is under 2.5 centimeters at birth, for a full-term baby. The average size of a penis at birth is approximately 3.5 centimeters.

How big is a micropenis?

Having a penis one centimeter or more shorter at birth than the average is considered a micropenis. In most cases the shortened penis size can be corrected.

How many men have micropenises in the USA?

Having a micropenis is considered a rare condition. The Cleveland Clinic reports an estimated 3 cases in every 20,000 men births in the United States. Many men confuse having a micropenis with penile turtling (where penis may be hidden) or Peyronie’s disease (where it appears curved, angled, or bent).

Morganstern Health has developed the latest treatments to correct the conditions of a micropenis, penile turtling, or Peyronie’s disease.


Treatment options vary and have been researched for effectiveness.

Which is the best treatment option to correct micropenis syndrome? The best treatment option for micropenis disorder or syndrome is surgery. This treatment is supported by the National Center for Biotechnology InformationU.S. National Library of Medicine. According to the Journal of Clinical Research in Pediatric Endocrinology, surgery is a viable option for effective treatment.Enlarging the penis surgically results in permanent correction and resolves both sexual and urination issues.

At Morganstern Health many patients come to us looking for an enlargement of their birth penis which they have considered small from the beginning. These men want to gain enough size to hang down and feel confident with their partner(s).

Why is my flaccid size so small?

There is no correlation between a man’s flaccid and erect size. There is no formula that can be used to predict the length of an erect penis once the flaccid length is measured. Proper measurement can be performed by an experienced urologist to determine whether you may have micro penile syndrome.

To gain size, there are two main treatment options:

  • Instant enlargements (not permanent)
  • Permanent surgical enlargements

What if you don’t have a micropenis?

Some men already have what is considered average or larger sized penises, yet want to extend their penis even longer or wider. If you are wanting to go from medium to large or large to extra large (XXL), Morganstern Health would love to have the chance to discuss options with you.

Micropenis Correction

Some men simply have the genetics resulting in a smaller than average penis size. We will discuss the best options to enhance inordinately small penises at birth which remain small into adulthood. What exactly are micro penises and what is micro penile disorder? Morganstern Health provides the answers to correct or enlarge the size of a micropenis.

Development of Micropenis In Utero

This condition often results from abnormal testicular development. In many instances the penis simply did not grow in length as it should have in the first trimester of development in utero. There is often a reduced level of testosterone in men with this condition.

Common Complications and Functional Issues

Having a small penis at birth can present a number of issues. The obvious problem is a possible difficulty in performing sexual intercourse. Other common problems occur with urination and fertility. For these reasons medical professionals are terming the condition as micro penile disorder or micro penile syndrome. Research studies estimate that fewer than 1% of American men are born with this condition.1 Men that were born with micro penile syndrome often seek treatment and are glad to find out the condition can be permanently corrected.

Micro Penile Growth Surgery

What can be done to enlarge a micropenis? The best corrective solution is one that results in permanent growth and can be performed as outpatient. The procedure is called penis enlargement surgery in which the penis is extended in length and widened at the same time. Dr. Morganstern and the urology team can correct the condition by performing length and girth augmentation procedures simultaneously. In fact, he may be the only surgeon in the country who can increase both length and girth in the same operation.
