I just curious is it possible to combine the CursePenisGrowth and CurseWomb files and have both effects happen? And if so what would it do?

If you attempted to do that you would be a fool.
You may end up with both, and CurseWomb is permanent.
Use hypnosis to achieve somthing that you want, not to fool around

Your mind would most probably reject them anyway as they pretty much contradict each other.
