How is materbation according to the medical background?

I know that sometimes it looks weird to take the personal things out, but sometimes the things which someone do, should also know the consequences . so if you know something about it.. lease share it.. as it has always been a topic to think about and having a lot of confusions between people, regarding this... and please don't talk here about ethics or religious things.. just on medical background..
