Micropenis: why is my penis small?

We speak of micropenis if the penis of a little boy is less than 1.9 cm (0.7 inches) in length and if this small size is not associated with any malformation.

To learn more about the micropenis, discover all our information gathered in this sheet.

The micropenis, what is it?

From birth, we speak of micropenis if a little boy’s penis is less than 1.9 centimeters (0.7 inches) in length (after stretching and measured from the pubic bone to the tip of the glans) and if this small size is not associated with any penile malformation.

The appearance of a micropenis is usually due to a hormonal problem. If a treatment is not put in place, the micropenis can persist in adulthood. The man then presenting a penis of a length less than 7 centimeters (2.7 inches) in the flaccid state (at rest). Even though its size is small, the micropenis functions sexually normally. At the start of puberty, the limit for talking about a micropenis is 4 centimeters (1.5 inches). Then less than 7 centimeters (2.7 inches) at puberty.

The penis begins to grow from the seventh week of pregnancy. Its growth depends on fetal hormones. The penis contains corpora spongiosum and cavernosum, the corpora spongiosum surrounding the urethra, the channel that conducts urine outward. The penis grows over the years under the action of testosterone. Its development is amplified at the time of puberty.

Why is my penis so small?

In adulthood, the “average” size of a penis is between 7.5 and 12 centimeters (2.9 – 4.7 inches) at rest. And between 12 and 17 centimeters (2.9 – 6.6 inches) during an erection.

The difficulty encountered by health professionals in detecting a micropenis. Is that men often tend to find their penis too small. In a study of 90 men consulting for micropenis. 0% actually had a micropenis after examination and measurement by the surgeon. In another recently published study. The 65 patients referred by their doctors to a specialist for micropenis, 20, or about a third, did not suffer from micropenis.

These men thought they had a penis that was too small. But when a specialist took the measurement after stretching it, he found normal measurements. Some obese men also complain of having a very short penis. In reality, it is often a “buried penis”. Whose part attached to the pubis is surrounded by pubic fat, making it appear shorter than it really is.

Penis size has no bearing on fertility or male pleasure during sex. A penis, even a small one, allows you to have a normal sex life. However, a man judging his pp too small can be complexed and have a sex life that does not satisfy him.

How to diagnose micropenis?

The diagnosis of micropenis goes through the measurement of the penis. During this measurement, the doctor begins by stretching the penis 3 times, pulling gently at the level of the glans. Then he releases her.

The measurement is made with a rigid ruler from the pubic bone, on the ventral side. If a micropenis is diagnosed. A hormonal assessment is carried out to find the cause of the micropenis and treat it as well as possible.

Micropenis: what are the causes?

The causes of micropenis vary. In a recently published study, of the 65 patients followed, 16, or almost a quarter. Did not discover the cause of their micropenis.

The causes of a micropenis can be hormonal (the most common case), linked to a chromosomal abnormality, a congenital malformation. Or even idiopathic, that is to say without known cause, knowing that environmental factors probably play a role. role.

A study conducted in Brazil thus suggested an environmental cause for the appearance of a micropenis. Exposure to insecticides during pregnancy could thus increase the risk of genital malformation.

Most cases of micropenis are ultimately due to a hormonal deficiency linked to fetal testosterone during pregnancy. In other cases, testosterone is properly produced but the tissues making up the penis do not react to the presence of this hormone. This is called tissue insensitivity to hormones.

What are the symptoms of a micropenis? Its risks? And how to prevent it?

All the answers to your questions can be found below.

Micropenis: symptoms

A micropenis is a penis of small size, that is to say less than 1.9 centimeters at rest and after stretching at birth, or less than 7 centimeters in adulthood.

Micropenis: who are the people at risk?

People who suffer from trisomy 21 or Klinefelter syndrome (this syndrome corresponds to a chromosomal anomaly. The boy having 47 chromosomes including one Y and two X while the normal karyotype is 46, XY for a man) have a higher risk to suffer from a micropenis.

The same is true for children whose mothers received anti-androgen treatment during their pregnancy. (androgen hormones, of which testosterone is one, are responsible for male characteristics such as penis size, facial hair, musculature, low voice…).

Children who have cases of micropenis in their family also have a greater risk of suffering from micropenis in turn.

Micropenis: the risk factors

Cryptorchidism (testicles that do not descend into the purses) increases the risk of micropenis. Just like exposure to certain chemical substances such as endocrine disruptors.

How to prevent micropenis?

As exposure to various chemicals is suspected of increasing the risk of genital malformations in little boys. Some doctors advise eating “organic” as soon as you want to have a child and for the duration of your pregnancy.

The essential in the micropenis remains screening. A micropenis should be detected at birth in order to apply appropriate treatment to the child.

In young children, in case of hormonal abnormality, hormonal treatment can be effective.

Hormonal treatment

In young children, in the event of a hormonal abnormality, the treatment may consist of testosterone injections. The dosage and regularity of which are determined by the endocrinologist. This well-monitored treatment increases the size of the penis. When the micropenis is due to tissues of the penis insensitive to testosterone, this hormonal treatment has no effect.

The earlier the micropenis is detected, the sooner the treatment is put in place, the more effective it will be. Treatment may also be necessary at the time of puberty. After puberty, hormonal treatment is no longer effective because the tissues no longer react in the same way.

Surgical treatment

In adulthood, when the micropenis has not been treated or when the treatment has not been sufficiently effective, surgery is possible. However, it does not always present convincing results.

The section of the suspensory ligament of the penis, which goes from the penis to the pubis, can be proposed. It does not modify the penis in any way but detaches it partially from the pubis, making it appear longer. The gain observed is 1 to 2 cm in the flaccid state and 1.7 cm in erection. This elongation is acquired at the cost of an unstable erect penis, since it is less well attached to the pubis. Which can make penetration less easy.

Autologous fat injection involves injecting the subject’s fat under the skin of his penis. This does not lengthen the penis, but makes it visually thicker. Only part of the fat put in place is not absorbed by the body over time (10 to 50% depending on the subject). Resorption may be uneven and result in a “string” penis appearance.

The micropenis can have significant psychological repercussions, especially during adolescence. It is important that the person be helped and his doubts taken into account.

Urologist opinion

“Many men fear suffering from a too small penis because of two factors. The influence of pornography which chooses actors for the excessive size of their penis and the lack of self-confidence. In reality, the micropenis is rare and the majority of these men have a perfectly normal sex.

Some suffer from dysmorphophobia and fixate on the size of their penis. In this case, it is a psychiatric illness that is difficult to treat since these men tend to have surgery and re-operation without ever being satisfied.

When a man actually has a micropenis or a rather small penis. The main thing is to accept yourself in order to develop a fulfilling and happy sexuality. And it is possible. One of my patients told me one day: “the only time in my life where I had an orgasm was with a man whose penis was so small that the condom did not hold.
