I thnk there was something about risperidone and adolescent boys. Something like it raised prolactin levels and made them develop breasts. I remember seeing one of those class action lawsuit commercials here in the US during daytime tv. I don't know any details, just that I saw that. I am female and was on risperidone for most of my adolescence and it did raise my prolactin. I started lactating, which was extremely humiliating and I never told anyone about it. I'm not sure why I was put on it in the first place so I can't say if it helped.
