it was stated by Wayon from DS9 that the Breen homeworld is not a frozen tundra but rather moderate climate and that they wear the "Cold Suits" for an unknown reason. Maybe the STO team can come up with something interesting.
That was just Weyoun speculating. Vorta are devious, sneaky, coniving, and duplitious. He likely believed that since the Breen act in a similar fasion, that they were probably lying, just like he would do. As for Female Breen, a simple solution would be to have their heights about a foot shorter, change the gender designation, and no one is the wiser.
who says breen have gender? who said that breen is a male if they do have gender? its wearing a space suit that it cant take off because it needs tempuratures that would freeze you to death instantly to keep itself alive. unless you are staring directly into its genitles somehow i dont see how you can claim to know what gender it is. give it a girly name and get over it! if you want the entire crew to have boobs and baby maker hips then dont use the breen.
My Breen officer is most definitely a female. Suit just hides the curves. It's a shame I can't even change the color of the suit to match the rest of my crew. Makes her stick out even more than she does already.
