No, the sperm that males produce are produced are produced from scratch in the testes after they have developed to a productive state during puberty. which in Western Europeans is about age 13. it takes about 70 days for a sperm to develop to maturity. once sperm production has started a male will keep producing for the rest of his life.

Age. The older the male, the more likely that he will have spermatozoa, or sperm, that may result in birth defects if he makes a baby.Some may disagree, but the above comes from a recently published study on the causes of autism.
The male body, from puberty into old age, is continuously producing sperm. Unlike the female body which is born with a certain number of eggs and never produces anymore.
Men produce sperm constantly. There are millions of sperms cells in the male testicles, and the amount produced increases once a male reaches puberty.
