If I may ask, and this is not meant to offend you, why is gender important? In my experience with volunteering at shelters and/rescue etc., I have found that it is far better to evaluate a dog or a puppy based on their temperament, and behavioral characteristics, not on gender alone.
The reason why I say this is I'd hate to see you miss out on your perfect match, simply because it happens to be a he rather than a she.
Good luck in your search - I hope you find what you're looking for
