Difference b/w masturbation & wet dream

Does masturbation & wet-dream have the same losses in terms of sperm? They say that wet dreams happen in the earlier days of retention to have your body get rid of the old semen. Isn't that pretty much the same as masturbation in terms of sperm & Testosterone loss? (Not going into the brain and dopamine functions coz right now I'm only concerned about sperm losses)

I'm asking this coz usually by 50th day (in my previous streaks), I started getting the phermones-looks. Not this time. I've had 4 wet dreams in this streak with the last one just last week. I had also been drinking ~3 L of kefir milk every week.

Wanna know how long into the streak did you guys stopped having wet dreams?
