Blood UK just sent me a newsletter saying From summer 2024, we’re becoming more inclusive. People registering to become a donor will also be asked for their sex assigned at birth, as well as currently being asked for their gender.
This fantastic news! It always worried me that young trans men might be giving blood more often than was safe, as they would be on the system as men (who can donate more often). I do wonder if that has happened, or other harm, over however many years they have just asked for gender.
