Why Is My Penis Small | Why Is My Penis So Small And Tight

If you’re not happy with your current penis size, well, there are a couple of solutions. Of course, not all of them will work, and success will largely depend on the reason you have a tiny dick.

The good news is that most men think their penis is small. So, maybe you just need a change of perspective. If you don’t think this is the case, however, and are certain that your penis is, in fact, smaller than usual, then we can offer you some hope below.

Why Are Some Penises Small?

Why some penises are small

There are a number of problems a man can have with his penis. One is an abnormally small penis. It’s called micropenis or a very small penis. And it can be inherited from your father. It’s a problem that affects about 1% of American males. 

There’s no one-size-fits-all answer for penis size. Many men have penises of various sizes, from the very small to the very large. For most men, the average is somewhere in the middle. The number of erectile tissue cells varies from person to person. The total amount of blood that a man can ejaculate depends on how well his erectile tissues are functioning.

How do we decide what’s small?

A lot of men don’t realize that their penis size is average. It’s not unusual for most men to believe their penis size is smaller than average. If that’s the case, it’s important for you to know what a man with a normal-sized penis looks like and how to measure your own penis size.

Standby Length & Erect Size

As we all know, the harder the penis, the bigger it is. This is why there’s not one length of your penis, but a maximum length and a minimum one. We call this a penis’s standby length and erect size.

Indeed, a penis that’s flaccid (standby length) can be surprisingly large when hard (at its maximum erect size). 

The length of the average flaccid penis is between 3.4 and 3.7 inches. Conversely, the average length of a fully erect penis is between 5.1 and 5.7 inches. 

An Average Size

Like we mentioned above, the average erect penis length is about 5.1 to 5.7 inches. In general, the larger the penis, the more sensitive it is, but it’s important to note that penis size varies between men.

Most men who are in the 5-inch range are average-sized, but some men are very small and some are very large.

When Does Penis Stop Growing

Penis growth usually begins around age 9 and continues until adulthood. The length and girth of a penis doesn’t change much after puberty. 

The average penis growth rate during puberty is about half an inch per year, but this rate can vary from one male to another.

The Types Of Small Penises

Types of small penises


A micropenis occurs in about 0.6% of all men. It’s medically defined as a penis that is less than three inches long, or two-and-a-half inches if the penis is recessed. An SPL of three inches or less indicates a micropenis.

A man who’s penis is longer than three inches is unlikely to undergo surgery for it. Doctors don’t recommend it because it’s risky and controversial.

Most cases of micropenis are not discovered until adulthood. It’s often caused by genetic or hormonal abnormalities that cause other, more serious health problems early in life.

The penis starts developing in a fetus at about 8 weeks old. By week 12, the penis has developed and begins to grow. During the second and third trimesters, male sex hormones cause the penis to grow to its full length.

Hormone levels are key to the health of your penis. Factors such as stress, diet, drugs and environmental toxins can interfere with the production and function of these hormones.

Inconspicuous Penis

In men, the penis is the most visible part of the male anatomy. But sometimes the shaft is missing, is smaller than average, or doesn’t look like it belongs to the rest of the body. All of these things are called “inconspicuous penis” and they are usually caused by a condition called hypospadias.

While the genitals of newborn boys appear very different than girls’, many of those that are born with an inconspicuous penis do not have an obvious gender. Many experts will point to the genes determining the genitalia. For instance, if a mother has a son who was born with a penis that looks more like a clitoris and a daughter born with a penis that looks more like a vagina, they might say that is because of a recessive gene. If all of the brothers born to the same parents also have an inconspicuous penis, it could be because of a dominant gene.

An inconspicuous penis may be normal or due to injury or disease. It may be a sign of a congenital disorder or another condition. It may be a sign of testicular problems (infertility or low sperm count), an infection, or even a psychological problem.

What Are The Reasons For Small Penis

Men can experience shrinking of the penis as they age. But, there are many other reasons why a penis may shrink, including:

Weight Gain

A man’s penis does not shrink with weight gain. Instead, it’s pulled in by the abdominal wall as the belly expands. The penis should regain its normal shape and size when the body’s weight is reduced.

Prostate Surgery

After a radical prostatectomy, it’s common for the penis to shrink. Some studies have found that 71 percent of men who underwent this surgical procedures experienced some penis shrinkage.

Researchers don’t know why men’s genitals shrink after a radical prostatectomy. Some say the urethral tube, which connects to the urinary bladder, shortens during the procedure.

Peyronie’s Disease

The most common cause of erectile dysfunction is a medical condition called Peyronie’s disease. It can cause the penis to be bent, curved, or crooked, and overall looking diminutive. It can be treated, but it is important to see your doctor if you experience any of these symptoms.

If your penis isn’t curved, and you’re concerned about it, there’s a chance that Peyronie’s disease could be the cause. If that’s the case, then you don’t need to worry. The condition may improve on its own, or you might be able to treat it.

It can make sex painful and may cause you to have trouble getting an erection. If you suspect you have Peyronie’s disease, call your doctor. You may need to take medication, have the scar injected with a medication, or have surgery to correct the problem.

You may be prescribed additional medications, too. If your disease is not responding to treatment, you may need to consider other options, such as surgery.


Medications that cause penis shrinkage include Adderall, antidepressants, antipsychotics and some drugs prescribed to treat an enlarged prostate.

According to a recent study, some men taking the drug finasteride to treat enlarged prostate reported smaller penis size and reduced sensitivity.

Another study published in the Journal of Clinical Oncology in 2013 found that some percentage of men taking dutasteride to treat prostate conditions experienced some form of penis shrinkage.


Cigarette smoking is among the biggest causes of erectile dysfunction. It damages the blood vessels of the penis, making it difficult for the penis to fill with blood and stretch to achieve an erection.

A study conducted in 1998 by the Boston University of Medicine looked at the erect penises of 200 men. The results of the study showed that men who smoked had shorter erect penises compared to men who didn’t smoke.

A study in Germany found that men who smoked had shorter penises.

Smoking is also linked to erectile dysfunction (ED). It’s been proven in a recent study that smoking is linked to ED, and that it prevents erections.

Can The Penis Shrink? 

If your penis has decreased in size, it may be because of a condition that is treatable or a set of habits you engage in that you need to change.

If you’re worried about your penis size, it’s important to consult your doctor. They can examine you and recommend ways to increase the size of your penis.

Erectile Dysfunction And Penis Size

If erectile dysfunction is impacting the length of your erection, then you’re experiencing a condition called impotence. This doesn’t mean your penis, when flaccid, becomes smaller.

So, technically speaking, erectile dysfunction doesn’t affect the size of your penis, it only hinders you from getting a strong erection.

How To Regain Or Retain Penis Size?

Regain or retain penis size

There are a few ways to retain (or regain lost) penis size, all of which depends on the cause of your penis shrinkage in the first place.

  • If you are overweight, losing weight will help to reduce the illusion that your penis is smaller.
  • Check your medications carefully to determine if any could be affecting the size of your penis. If you’re taking anything that’s causing penis shrinkage, then ask your doctor for the appropriate substitutions. 
  • While general physical exercise can help with penis size, it is important to make sure that you do not do penis exercises that could cause damage.


Yes, surgery can make a man’s penis longer and stronger, but the results are mixed, with success in only a quarter of cases. For those who qualify for such procedures, surgery risks significant complications, including infection, wound breakdown, and even death. Many patients also suffer serious side effects, such as impotence and incontinence, from the surgery.

In surgery, there are several approaches that can be used to increase the length and girth of the penis. Some involve the use of implants to add length and width. Others involve the transfer of fat from other parts of the body to increase the size of the penis.

There are very little medical reasons for having penis enlargement surgery. If your penis is smaller than 7.5 centimeters when stretched, you may have a condition called micropenis, which is among the few conditions where surgery can be recommended.

But no matter how inadequate you feel, if your penis functions normally and is within the normal range in terms of size and girth, then surgery isn’t recommended.

While having a small dick can be frustrating, it’s important to keep in mind that it’s not, by itself, a medical condition.

If your penis has shrunk, however, then, depending on the underlying medical reason, there are options available for you. These coupled with the proper lifestyle changes will work for most, so don’t fret.

Remember, your penis is a part of your body that should be cared for, and it should be treated with the same respect as your other body parts, if not more so.
