eli5 If a man were to hold off his sperm for years, have sex and then have sex again the next day, would the old sperm reach the egg before the new sperm would?

Question

Is the old sperm less healthy than the new sperm? Will it produce children with deformities? How does this whole old new sperm science work?

Answer 1

Sperm dies off and gets removed and replaced every couple of months. All sperm is “new” sperm. Abnormalities can occur with age, I’m not sure what age it is though.

Answer 2

Your body continually makes it. Often being discharged in your urine.

None of it’s old.

Answer 3

No.

A healthy young man produces well over a hundred and fifty million sperm every day, and a healthy older man about half that.

Men shed nearly that many daily just by “leakage” into his urine stream to be flushed out, or dripped out, unless he has a wet dream or otherwise ejaculates.

You would never have sperm that were years old unless you froze them.

Answer 4

yes it would be faster because it can spend more time in the balls-gym, resulting in superior sperm-leg-strength. unless it’s too old, then it gets sperm-rheumatism.
