Well I have seen that comparison made mostly between Shoujo and Shonen mangas, or mangas aimed at female or male readership.
Let use some extremes for comparison.
Here's the art of the group CLAMP, a circle of influential women mangaka.
Notice the chins that can puncture your eyes and the long slender limbs and the big, lovingly detailed eyes.
And here's One Piece by Eichiro Oda. Which is about as Shonen as it gets.
One Piece might not be such a good example since the artists as really elastic sense proportions, but you can notice that the features tend to be more restrained and more rounded. Harder, less flowing lines.
Of course, it's not necessarily a masculine art-style. After all, perhaps one of the best example of this is Fullmetal Alchemist, by Hiromu Arakawa.
And then you have the extreme of masculine drawing, which parallels the horror that is human anatomy in western comics.
Sometimes the two opposites happen in one author. Like JoJo's bizarre adventure by Hirohiko Araki.
Jojo Part 2
Jojo Part 5
Jojo, though, is kind of a category of its own.
