Is masturbating a solution to remove dead sperms inside the testes that i think is twice exposed to xray? how many times? i want to have a normal baby

I wouldn't worry: If you want to masturbate go ahead.I wouldn't consider it necessary or helpful. X-rays have little effect on the production of sperm and if it did the ones affected would be the poor swimmers. It is a benefit to all babies that the healthiest sperm swim the distance & do the deed. That lets dad off the hook for some of his bad habits & improves outcome.
