Of course, donors of every gender are welcome and encouraged to give blood. However, during pregnancy, women often make new antibodies, which can make it harder to match their blood with a patient’s. Men’s blood may contain fewer antibodies against red and white blood cells, which means it can be used for creating better matched blood products to treat patients – such as platelets for cancer patients and allogeneic serum drops for people with dry eye conditions.'
Every gender

Then they link pregnancy to women which is clearly transphobic. And make generalisations about men's blood.
They don't mention non binary blood at all!
