does testis reproduce sperms again once they have been lost or not?

Question

I mean the times that you can have sex are limited (you will run out of sperms after too many times)or not?

Answer 1

your testes are constantly craking out sperm. The sperm are stored in the top of your testes to mature (grow)

after you ejaculate, the sperm is gone, but your testes will produce more.
