[The Saucepan Man]

Galadriel was tempted but passed the test. Otherwise, I don't really think that the Ring really had any opportunity to try working its powers on any female characters.

It might be argued that men are generally more hungry for power, and so less resistant to the Ring's wiles. But the Ring doesn't just promise power. It uses whatever is in the hearts of those it is trying to tempt. For example, in Sam's struggle with the Ring, it tries to use his desire to help Frodo.

So, I see no reason why women shouldn't be just as vulnerable to it as men.
