Does DNA determine your penis size?

Yes, mostly. Your genes are the biggest factor in determining your penis size, the same way they influence your height, your shoe size, and most other physical traits.

There's no single "penis size gene." It's a combination of genetics inherited from both parents. Hormones also play a role, especially during puberty when testosterone drives growth. Things like nutrition and overall health can have a small effect too, but genetics is the main one.

You can't change your DNA, and there's nothing you can do to make your penis bigger. If you've seen products or exercises online that claim otherwise, they don't work.

If you're still going through puberty, your penis probably hasn't finished growing yet. It's often one of the last things to reach its full size.
