Hello,Just want to know about the difference in " outcome" of my sperm.I am 70 yo and still enjoy masturbating since I have no partner to play with .Since several month now my sperm does not look the same :  whitish and creamy,  as usual,  but more waterly and transparant like if it is more about precum . ?Waht can cause this change. ?Thanks for your answer.
As the age advances semen production also decreases. More semen production makes it more thick.in old age, as its production decreases makes it more watery. Also over masturbation (more than once a day)can cause watery semen.
