Unknown: Are you 20 or 16? Either way, your fertility status can only be determined by testing or a successful pregnancy. Your smoking is foolish and you should stop now. Masturbating a lot won't make you sterile.

Why do you ask?: Smoking may reduce fertility in some men, but usually only marginally - reduced numbers of sperm, abnormal sperm formation and reduced sperm motility. Masturbation does not have any deleterious effect on fertility either. If you are 16 (rather than 20), fathering a child is probably not in your best interests now. If you and a partner are trying to get pregnant, you need medical testing to see.
