Should you be able to produce sperm when you first hit puberty?
Puberty is defined as the time when your hormones begin to rise from their childhood levels on their way up to your adult level. The rise in hormones trigger many changes in your body, but those changes take time to happen. When you reach puberty your testes, where sperm is created, begin to grow, but it is not until one or two years later that they mature enough to produce sperm. When you reach the point that you are able to ejaculate, you will know that your body is actively producing sperm.
