Seren indicated that Mah lost a portion of her power for each thing she created. Perhaps there was no creating and only the shaping of what already was.

As such, she may have indeed preferred Zaros and her male creations in general for the fact that they were distinct from her. And that's maybe whycome there's more male than female mahjarrat. Because my answer is way better than that judgemental mahjarrat jerk's >.> I reserve the right to relentlessly edit this post many, many times over.
