Is Penis Size Genetic?

Have you ever wondered about the size of your penis? Most people who identify as men have worried over their penis size at one point or another. Some men worry that theirs is too small while others are concerned that it’s too big. The general population cares a lot about penis size but few people know about their penis size, including how it was determined and whether or not they can change it.

Along with your sexual function, your penis size can shift with your level of arousal, your age, and more.

So, is penis size genetic?


At the end of the day, all of the physical traits you have are inherited from your ancestors. This means that your penis size is — for better or worse — the luck of the genetic draw. Your penis might not appear similar to your father’s or his father’s in any way, but a variety of genetic factors have led to the size of your penis, its shape, and even its coloring. According to a recent article posted by Fatherly, scientists have found that your penis’ size is impacted by genetic components from both sides of your ancestral tree.

“There are some genes in the Y chromosome that have links to penile lengths and size,” reports urologist Dr. Jamin Brahmbhatt in an interview with Fatherly. ” So you can’t entirely blame your mom for your small penis.”

Does your penis size change?

It’s important to keep in mind that your penis continues to grow through puberty. In fact, you didn’t even have a penis until you reached at least seven weeks old in the womb. But when you’re born and reach puberty, your penis will start to grow and change, along with your fertility, desire for sexual activity, and more. As such, you won’t have the same sized penis as you did when you were 10, 12, or even 18 years of age in some cases. In fact, studies show that your penis can continue to grow well into your early 20s, though it likely won’t encounter any big changes during this period.

Your penis size can also change depending on your level of arousal or other issues in sexual function. Most people tend to measure their penis size when they’re the most aroused since this is typically when your penis is the largest. But if you’re just looking at sex as another one of your daily activities, you might not reach your full size. If you’re encountering issues with sexual dysfunction, your penis will also be smaller because you’re unable to get hard. This happens to many men in the general population. Talking to a doctor about infertility, sexual dysfunction, or retrograde ejaculation is the best advice when this occurs.

Can I make my penis bigger?

In some cases, you can make your penis bigger, if only temporarily. Supplements like Viagara are designed to increase blood flow and improve sexual function. The same can be said for up-and-coming products like Erectin. They even offer the occasional free article highlighting the benefits of their products along with any prospective study that might come down the pipeline. If you want a bigger, harder erection, reading an Erectin Review online can help you make better decisions regarding your health. Of course, this should also be done in conjunction with talking to your doctor. After all, everyone’s sexual function is different.

Wondering about the size of your penis and your genetic factors is natural. But it’s important to remember that size doesn’t always matter and girth doesn’t always have to matter more than length. Talk to your doctor about your fertility and penis size to know about the safety options before you.
