Hi RT2015 - from my experience, they would not give me nationality, or profession. The information given was age, if she was a student or a professional (mine was a professional), eye colour, hair colour, skin colour, blood group, if she has normal BMI (but not weight), and if she has proven fertility (mine did). Because of Spanish law I believe this is all they can give you.
In my initial correspondence, I was told they would provide "age, hair, skin, blood group, eyes, height, weight, if she is a student or professional, and if she has proven fertility."
When they confirmed the donor and I queried that the weight and height were missing they said "we are not allowed anymore to confirm weight or height according to the law. We can only say that the BMI is healthy and she must have a similar complexion like you."
Perhaps there was a change in Spanish law. Anyone know?
