Can sperm cells ever run out?
Question in full: can sperm cells ever run out
The short answer is no. In 2007, an Indian farmer fathered his 21st child at the age of 90! While this is on the extreme side, the point is that you go on producing sperm into old age. Equally, you will not “run out” of sperm if you masturbate frequently. You do lose sperm when you ejaculate, but your testes (balls) are very efficient at reproducing large numbers of sperm cells very quickly. So do not worry!
