Greening said he thought the reason why sperm quality improved with frequent ejaculation was because the sperm had a shorter exposure in the testicular ducts and epididymis to reactive oxygen species - very small molecules, high levels of which can damage cells.
Greening said he suspected that the longer sperm stays in the testicular ducts, the greater its exposure to rogue oxygen molecules that damage cells.
