      Hi whatarethose,

      Thanks for your question. Sperm are made by a process called spermatogenesis. Here is a great video that can help explain this: https://www.youtube.com/watch?v=ZFLb19nC2bs

      Sperm start to form in males around puberty. Like other cells in the body there is a process of replication and division. In sperm this process gets the correct genetic information from a male into the correct form (1/2 of all genes for a potential new life). This process takes place within the testes of the male and sperm stay there to mature.
