I have not really heard of anything like that although maybe there is some marketing differences in companies. Nothing is really coming to mind though.
I think some of the whiskey can be too hard. And so not many women prefer them. But usually you can see that there are not many gender specific whiskey out there. And so I guess it's pretty much neutral.
I think they can drink any kind of whiskey they want these days,when it comes to the ladies-and I have even heard of a woman that has her own distillery in Scotland, also they say that Lady Gaga drinks Jameson Whiskey(and really likes this brand). I think some women drink better whiskey than men these days, like in the video below(haha)!
