Is it true if you jack off too much your sperm quantity decreases?

Probably: Masturbation to extreme will lower ones sperm count. It simply supply and demand. If one were having difficulty getting pregnant, we would ask to have a period of rest prior to the time of ovulation and then have intercourse. If pregnancy is not the issues, it really doesn't matter unless you are taking things into your own hands way too much!

Not for healthy guys: You're from a community in which there's a lot of superstition and actual lying to young people in the name of "spirituality." sperm counts go down if you ejaculate often simply because less fluid is reabsorbed between ejaculations. Stop listening to people who are trying to confuse and frighten you. Embrace who you are, stay comfortable, and love responsible when the time comes.
