When we fatten cattle, some of the females are given male hormones. The reason for this is that it makes their muscles a bit bigger and makes the steaks and roasts a bit bigger. The hormones are used up long before the animal is butchered so as not to remain in the meat.

However, there is a big warning label on the boxes of implants. It says Do not use on animals to be kept for breeding purposes. It messes them up for obvious reasons.

Will all the "trans" stuff affect population stability? Probably.
