In brief: Many things...

Sperm is produced new in the testicles about every 10 weeks.
Over time, things can change. Age can affect sperm over time, as can something called a varicocele. Reproductive toxins in our food, water, air, and workplace can also cause sperm to deteriorate over time. I hope this helps!
