'Grow your own transplant' may be possible for men with type 1 diabetes (http://www.medicaldaily.com/news/201012 ... abetes.htm)

Men with type 1 diabetes may be able to grow their own insulin-producing cells from their testicular tissue, say Georgetown University Medical Center (GUMC) researchers who presented their findings today at the American Society of Cell Biology 50th annual meeting in Philadelphia. Their laboratory and animal study is a proof of principle that human spermatogonial stem cells (SSCs) extracted from testicular tissue can morph into insulin-secreting beta islet cells normally found in the pancreas. And the researchers say they accomplished this feat without use of any of the extra genes now employed in most labs to turn adult stem cells into a tissue of choice.

Well, that's wonderful for intact men, but what about us eunuchs? What about women? This is unfair, I don't have any testicular tissue, this is prejudice, I'm sending them a formal complaint. Had I known that they were working on this, I would have... no, no I wouldn't have. Getting castrated, losing my testicles was the best thing I ever did for myself. For you who have diabetes, this is wonderful news, for me and my fellow eunuchs, we'll find another way.
