Purpose of this document is to provide information to patients with a micropenis (or parents of a micropenis boy) about the currenly available treatments for the micropenis conditions. The information is copy pasted from various sources thus I claim no copyright on this document. If you are unsure of what a micropenis is, please visit this micropenis site. Let’s begin:

Treatment no1: Testosterone therapy

Growth of the penis both before birth and during childhood and puberty is strongly influenced by testosterone and, to a lesser degree, growth hormone; but their value in the treatment of micropenis is mainly limited to conditions of hormone deficiency, such as hypopituitarism or hypogonadism. Regardless of the cause of micropenis, if it is recognized in infancy, a brief course of testosterone is often prescribed[4] (usually no more than 3 months). This usually induces a small amount of growth, confirming the likelihood of further growth at puberty, but rarely achieves normal size. No additional testosterone is given during childhood, to avoid unwanted virilization and bone maturation. (There also is some evidence that premature administration of testosterone can lead to reduced penis size in the adult.)[5] Testosterone treatment is resumed in adolescence only for boys with hypogonadism. Penile growth is completed at the end of puberty, similarly to the completion of height growth, and provision of extra testosterone to post-pubertal adults produces little or no further growth.

Treatment no2: Phalloplasty (performed on adults)

This is a risky option that may or may not work though. The human penis is partially hidden by the pubic bone and partially visible. What a phalloplasty operation do is to make the hidden part more invisible so that the penis hangs more on the outside.

This is a dangerous option that can have severe side effects like having the penis pointing in the wrong direction!

During the surgery, the doctors first took a free radial forearm flap and used it to create a new penis of average length and diameter. Next, they wrapped the flap around the patients' micropenis and placed a penile prosthesis inside the flap. The prosthesis would allow the patient to have an erection on demand.

A study on phalloplasty for micropenis concluded:

"Free transfer of the radial forearm flap may be done in select men with micropenis associated with vesical exstrophy for penile reconstruction. An inflatable prosthesis may be inserted in the flap to provide erection. The results of this technique have remained stable in the long term. This method provides a new tool for phalloplasty in these difficult cases." extract from the study.

Treatment no.3: hCG Treatment (again for adults)

In 2011 a study was conducted named Penile Growth in Response to Human

Chorionic Gonadotropin (hCG) Treatment in Patients with Idiopathic

Hypogonadotrophic Hypogonadism. In this study a total of 20 men participated all

presenting with  hypogonadotrophic hypogonadism and micropenis as well.  The

subjects were given 24 injections containing Human chorionic gonadotropin

hormone. The injections were giver 3 times a week for a total of 12 weeks.

During and after the end of the study penile length and testicle volume was

measured. All measurements were taking by the same doctor to avoid errors due to

different methods used. The results are as following

Penis length

According to the study’s findings the penile length increased from 3.39±1.03 cm to

5.14±1.39 (more than 50 % increase)

Testicle volume

Testicle volume increased as following:

From 5.45 cc to 6.83 cc for the left testicle

From 5.53 cc to 7.03 cc for the right testicle

Penis length and testile volumes were re-measured 4 months after the end of the

study to test whether the results were permanent or not. It was shown that both of

the gains were sustained.

The researchers also reported a substantial  increase in the mean serum

testosterone concentration, which is good as all patient had testosterone deficiency
