It can do. It's all about nuture versus nature right? Well I believe it is a combination of both. Although I was told the other day that apparently by the third child, the female body will try to produce a girl if it hasn't already and if they have another male he will most likely be homosexual. I have no idea if this is true, It was funny to laugh at as people started naming the third male in families and realising they were efeminate or homosexual...:S
