Is masturbating regularly cause infertility?

No - Masurbation is not a cause of infertility, but it can cause a temporary lowering of your 'mature' sperm count. Since the amount of 'mature' sperm in your system depends in part on how long a man goes between ejactulations. However, everyday, a man鈥檚 testes are busy producing millions of sperm. An average ejaculate contains 40-150 million sperm. It takes about 2-3 months (about 74 days) for sperm to mature. However, there is constantly sperm in production waiting to mature and learning how to swim, getting ready for the next ejaculation. It is a constant process.

Sperm count can be increased through a healthy lifestyle - good nutrition and exercise. Vitamin C is essential to sperm production and function, so taking a daily multivitamin containing this will also help. Also, avoid dehydration, smoking, and excessive alcohol consumption

Never, it will alway be fertility. Unless you get steriod, that can cause infertility.
Depends how often. It doesn't cause infertility, but it will lower your sperm count for a day or two. The same thing will happen if you sit in a hot bath. Good Luck ! :)
Good question that most guys do not have the balls to ask... The simple answer is No, it most certainly will not cause infertility, it will actually have the opposite effect. Your body will produce sperm to replace the sperm that is expelled by masturbation and if you frequently ejaculate, your body will just continue to produce. You will become more efficient and producing sperm and staying fertile as long as your body needs to keep producing sperm. Just be sure to switch arms so you do not end up with one big arm and one scrawny arm. Other than that, don't fear, you are just keeping your equipment in good working order...
