Will masturbation release hormones that close growth plates?

No: That's just one more myth, and whoever told it to you is somebody you should not trust. Being a teen is lonely and difficult enough without being fed disinformation. Perhaps there's an adult in your own family that you an talk with about the process of growing up, learning about your new body, and preparing to love as a responsible adult. Good luck.

No!: If that were the case, we would be a nation of very short people.
