They are available from teh NHS now, in selective places...a friend of mine was very poorly..after they tried everything, the Quacks said he needed a Brain Transplant.
Cutting edge, and risky..naturally...but there you go...I was there comforting the family at the time, he mentioned Prices...£5000 for a male brain and £200 for a female brain.
It was quite tough, coz all teh guys were looking at each other, trying not to laugh..so, I put my Jack Dee face on and asked, why such a difference in price.
The Doc said, they have to charge less for the female brains, as they have actually been used.
So there you go...
