A baby bot at the time of birth already has numerous immature sperm cells called spermatogonia. The pituitary gland is responsible for male sexual maturation too. Did you know that every day a man produces almost 10 million sperms, i.e almost 1000 sperms a second? Each sperm carries genetic material from the father. Sperms are produced in the seminiferous tubules of the Testes.
