The name of the human growth hormone suggests how it works. Numerous bodybuilders use HGH for muscle building, and it can also assist in promoting hair growth, as well as accelerating fat loss, wound healing, and injury recovery.
Since it focuses on growth, does HGH make your penis bigger? Is HGH a potential penis growth hormone? That is a question we are trying to answer about this article. Here is what you need to know about human growth hormone and penis enlargement.
How Big Should Your Penis Be?
You won’t find a unique answer when it comes to average or standard penis size. That is why the only sure thing to say is that your penis should be as big as necessary for you to feel comfortable having it.
It is important to mention that you should make a difference between flaccid and erect penis size. Penis has both length and circumference, and both factors affect its overall size.
Depending on the source, the average flaccid length is anywhere between 2.8 to 3.9 inches (from 7 to 10 centimeters).  Once erected, the average penis size is from 4.7 to 6.3 inches (from 12 to 15 centimeters). As for the circumference, it should be around 3.5 inches (8 centimeters) when flaccid and 4.8 inches (12 centimeters) when erect.
When Does Your Penis Grow?
According to experts, puberty is the time when your body develops, and that includes penis growth.  Depending on the male, puberty can begin as early as when you are nine years old or as late as 14.
Puberty lasts approximately five years, but that doesn’t mean the growth of the penis stops once you finish puberty. The scientists believe that growth continues until you are 20 years old or so.
They indicate that penis enlargement after that time is still possible. However, it is a little likely, and any changes that occur are usually not significant. The question is whether you can change that with the human growth hormone.
Does HGH Work as a Penis Growth Hormone?
We know that androgen hormones are in charge of giving men their specific traits, and that includes penis size. That is why even experts use the term “sex hormones” for androgens. 
The primary androgen in males is testosterone, a hormone produced by testicles. Apart from participating in sex organ development, it also affects muscle building, as well as secondary male characteristics, which include voice deepening and facial hair. 
Androgen deficiency during puberty could compromise penis growth. The underlying cause could be medical issues with testicles, such as undescended testes, losing them due to trauma, radiotherapy, chemotherapy, etc.
The pituitary gland found in your brain controls testicles.  That means it also affects testosterone production, and problems with this gland can lead to low testosterone in the human body. Benign tumors, as well as genetic conditions tied to the hypothalamus, which controls the pituitary gland, are common causes of these issues. Although it is a brain problem, the entire body is connected, and that’s why it affects testosterone production.
Why Are Testosterone and HGH Important for Male Sexual Health?
We already established that testosterone is an androgen. As a major sexual hormone, it has a massive influence on your sexual and overall quality of life.
Here is an overview of why testosterone is important:
- Sperm production – testosterone is what can increase the quantity of the sperm and boost its production.
- Libido boost – sexual desire is vital for every man, and testosterone plays a role in keeping males wanting sex.
- Muscle mass – testosterone plays a role in promoting muscle development and increasing lean mass.
- Strengthens bones – thanks to that, you have a reduced risk of fracture.
- Better mood – low testosterone causes irritability, fatigue, and depression. Optimal levels of this hormone put you in a better mood and get you ready for intense exercise.
Testosterone is an essential male sex hormone, but you shouldn’t forget the human growth hormone. You can find studies that show HGH plays a role in dealing with erectile dysfunction. 
This hormone also has a wide range of other benefits, including accelerated wound healing, fat loss, and injury recovery, as well as promoting joint health and muscle strength.
Since it a hormone that affects growth, HGH can also affect the penile size. However, HGH production decreases as time passes. That is why you might want to look for ways to boost this hormone’s production. The important thing is to find a high-quality product that can meet expectations and deliver what’s promised.
You can consider combining HGH and testosterone boosters. Both of these can promote your sexual health. They can increase your libido, make you feel better by looking better, and who knows, you might notice changes in your penis size, too.
What Does the Science Say?
An interesting study related to the effect of HGH therapy on testicular and penile size was conducted in 2014.  The research focused on 20 boys who had problems with GH deficiency, whether due to genetics or other reasons.
The study concluded that growth hormone treatment increased penis length in all but two participants. The size was brought to normal even in three participants who reportedly had very small penile length. That undoubtedly proved that human growth hormone could affect the penile size.
Another extensive study was conducted on rats with micro-penises in 2018. The research focused on combining testosterone and human growth hormone treatment for a penile increase.  The results of the study showed that growth hormone is an adjunct to testosterone, and it can assist in promoting penile growth while maintaining its structural integrity.
The science undoubtedly confirms that testosterone and other sex hormones affect penile growth. However, HGH can also assist in promoting penis size.
The only question remaining is whether boosting HGH and testosterone production can help with penile growth regardless of your age. Research indicates that not much change in penis size occurs after the age of 20 or so, but it also doesn’t exclude that possibility.
