Micropenises: What Are They and How Are They Caused

Reading time -

Micropenises are small penises. This is a term used to describe a penis that is smaller than normal for an average-sized adult male, and it can be due to several different factors. The condition can also be caused by poor blood flow, hormonal issues, genetics, and other factors. The term is used to describe the length of the penis; the penis will usually be less than 3 inches (7.6 cm) in length.

Many things can cause micropenises; however, they are typically caused by the same conditions. This is because the majority of men with micropenises (over 70%) will typically have the same underlying issue that is causing their abnormally small penises. This is known as hypogonadism, which is a hormonal issue. This is why it is so important to have a doctor take a look at your penis to assess any possible underlying condition that may be causing it.

What is a Micropenis?

The average erect penis length is about 5.5 inches (13.97 centimeters). The average flaccid length is about 3.5 inches (8.89 centimeters). If you are far below this range, measuring under 3 inches while erect, you may have a micropenis. A micropenis will typically cause the penis to be smaller than the size of an average-sized erect adult male penis on its own.

It’s estimated that about 0.6 percent of men around the world have this condition.

What Causes Micropenises?

There are a number of different things that can cause a micropenis. The most common cause of micropenises is known as hypogonadism. This is a hormonal disorder that affects the body's ability to produce testosterone. Testosterone is the hormone that is responsible for the development of male genitalia.


Hypogonadism isn't a male-exclusive problem, both men and women can be affected by it. It is a condition that occurs when there is a problem with the endocrine system. The endocrine system is made up of glands, and these glands release hormones into the body. These hormones will regulate and control a number of bodily functions, including those that regulate growth, development, and reproduction.

Hypogonadism is a condition where the testicles do not produce the correct amount of the hormones that they need to produce in order for a man's body to develop properly. This can result in a number of issues, with micropenises being one of the most common.

Can you cure hypogonadism? In some cases, yes. However, it can be a difficult condition to treat as it is so individualized. In cases of hypogonadism, the condition is caused by underlying conditions that have to be addressed. The underlying cause of hypogonadism will need to be diagnosed and treated, and this will need to be done by a medical professional.

Klinefelter Syndrome

A micropenis can also be caused by a hormonal issue known as Klinefelter syndrome. This is a genetic disorder that is passed down through the family lines. This is more common in people that have family members that have a history of having a micropenis. Klinefelter syndrome means that the person will have an extra X chromosome in their genetic makeup. This can result in a number of side effects, including micropenis.

The extra X chromosome will cause the body to have an abnormal hormone level. If this occurs when a male is still in the womb, it could result in a micropenis. It can also result in a number of other issues in a male's body, including a low sperm count. Many men with Klinefelter syndrome will experience fertility issues, and this can affect their quality of life.

Klinefelter syndrome is a genetic disorder. If you have a family member that has it, it is possible that you could have it too. However, you can't get it from someone that doesn't have it. To find out if you have Klinefelter syndrome, you will need to have a genetic test done.

Klinefelter syndrome is a genetic problem. There is no cure for it, but you can get help. You can get medical help to manage the symptoms. If you have Klinefelter syndrome, you may have a hard time in the bedroom, but a male enhancement pill could help you in that department.

Micropenis Treatments

For the best results, micropenises should be addressed as early as possible.

1. Hormone Therapy

Hormone Therapy is one of the most important treatments for micropenis since it can greatly increase the length and girth of the penis. Before beginning hormone therapy, you must receive a complete physical and psychological evaluation.

The main hormone that would be administered to the patient is testosterone. Testosterone is the hormone that is responsible for the development of male genitalia during fetal development. If there is a deficiency of this hormone in the womb, then the genitalia may not fully develop. Therefore, the administration of testosterone to the fetus can help in later development.

Apart from testosterone, the other hormone that would be given to the patient is DHT. This is an important hormone that can convert testosterone into dihydrotestosterone. This hormone is responsible for the growth of the penis during puberty. Therefore, the administration of DHT can be very beneficial to the patient.

2. Penis Enlargement Surgery (Phalloplasty)

Penis enlargement surgery is a procedure that is done to increase the length of the penis. It is a procedure that is done to enlarge the penis by using a part of the body. In most cases, the penis is enlarged by using the forearm tissue, using the erectile tissue of the penis, or using the patient’s abdominal tissue.

This surgery is both invasive and costly. Therefore, it is not normally recommended for patients who are not fully committed to the procedure.

3. Acceptance

Finally, since the condition is a congenital one, there is no way to reverse it. It is a condition that a person is born with and there is no way to avoid it. Therefore, the best thing that a person can do is to accept it and learn to live with it.

The best way to live with this condition is to learn to love yourself despite feeling unhappy with your physical body. Remember that sex will still be enjoyable for you and your partner if you listen to your partner's needs and desires.


Micropenises can be hard to accept, no matter their cause. The best thing you can do is discuss it with your primary care provider, to find out if there are treatments available for you, such as hormonal therapy. You may also want to talk with your partners about your condition, to work out how you and your partner will enjoy sex.
