Does meiosis occur after a male....?

s sperm? If so, doesnt that mean that the more a male releases sperm, the more meiosis which occurs, and so, the more likely it is that mutations may occur, or cancer, due to crossing over in prophase 1, and the genetic reortment due to random distribution and subsequent segregation of the maternal and paternal chromosomes in the logous pairs. Ahhhh, I'm confused. But please don't mock, I'm just a curious mind in search of an answer.
