Thanks, yes collapse is an option but I want to
calculate means and CI for each month not for the
whole period if I use collapse then I can not use ci.
Or this  is also possible?  


Then use -collapse (mean) male female ...- instead and see if that does you.

Anyway, if most of your data contains only 3 or 4 monthly observations on 
average, I do wonder if calculating CIs for your monthly means is terribly 
meaningful. If you think it is, plod on.
