We weren't picky.. we chose about 14! We picked various types, they all needed to have a photo, because you can say your 120lbs, blonde hair blue eyes, sounds great on paper. but if you see the photo they could have a giant hook nose, crossed eyes with coke bottle glasses a giant butt, balding stringy hair..the list goes on. Of course the medical part is very important- seems shallow? not really, I'm short dark hair and hazel eyes and flat chested.. our donor was beautiful! tall thin and great features- so I upgraded! Our twins are a spitting image of her! We are truely blessed! My advise is to get as much info as you possibly can on the donor. Little things they don't tell you. when did their hair grow in, when did their teeth grow in, first steps..did they cry through the night, first words etc.. genetic things that you have no control over! By choosing a big list of donors you will also be matched and able to start to cycle sooner. we didn't want to waste any time in getting the ball rolling. I was the same age as you. Good luck!
