No, there weren't many new women fans tuning in to Voyager to admire Jeri's wonderful shape.
There were, however, women fans who tuned in to admire Jeri's wonderful performance.
Or don't we count?
I hate to be the one to break this to you but no we don't count. We are not the "desired demographic". That is why the captain of the series could not be too feminine - the "desired demographic" might get freaked out. Also, despite the fact that Jeri Ryan turned in what has to be one of the best Trek performances in "The Gift" the reaction of the network suits was "Get her out of that borg costume and into something sexy."
Hey, nothing wrong with looking at an attractive person. After all, most of the Voyager cast gets paid to be much more attractive than most of us poor slobs who watch the show. Nothing wrong with a little sex either. However, in the case of Trek it's dumbed-down sex - titillation instead of passion, fetishism instead of reality. Why be adult about it.

As for the Mulgrew/Ryan drama what is more fun than the thought of a cat fight between two women? Were they professionals? Did they perform well together? The heck with that - we want to hear that Mulgrew spent each day on the set throwing donuts at Ryan.
One of my favorite stories is a new BSG interview with Katee Sackhoff where she was asked about her not getting along with Tricia Helfer. Her reaction: "I'm meeting her for a beer later. Why would I be doing that if I didn't like her?" How disappointing for the catfight fans.

Mulgrew and Ryan may not have been drinking buddies (since both were single moms at the time that wouldn't be realistic anyway) but they performed well together and seem to respect each other's talents. When you consider all the drama that goes on in the average workplace that's not too shabby, imo.
