I've just gone on to register my wishes, (link below if anyone else wants to do likewise).
I was concerned that under the new regulations requiring you to opt-out of becoming a transplant donor, it would not be possible to specifically opt-out of donating my reproductive organs.
In fact, if you opt to only donate some of your organs and select the ones you are happy to be used, reproductive organs are not listed as a choice, although "tissue" is, and I do wonder how widely tissue could be interpreted.
For now, I am choosing to opt-out of donating tissue, but would be willing to donate the other organs specifically listed.
Sadly, there is the inevitable question about gender. Even when talking about cadaver transplants, it would seem gender trumps biology.
