Besides a kidney, are there any other organs that you are allowed to donate?

Well according to Wikipedia, here's the list of organs that can currently be transplanted from a living donor. For something like a kidney donation, the donor has two and gives one. For something like a liver donation, they take a piece from the donor, which he can live without (and will be enough to help the recipient):

  • Lung
  • Kidney
  • Liver
  • Intestine
  • Skin
  • Islets of Langerhans (Pancreas Islet Cells)
  • Bone marrow/Adult stem cell
  • Blood transfusion/Blood Parts Transfusion
  • Bone
  • Heart valve? (Anyone know more about this?)

As far as I know, the halachic logic is the same for all of these: you're putting yourself at "some risk" (safek sakana) to save the life of someone in "serious mortal danger" (vadai sakana). (Okay with an ordinary blood transfusion your risk is quite minimal. With something like bone-marrow, from what I hear there's also a question not so much of risk but of pain.) The common psak l'halacha is that the Yerushalmi requires one to put himself in some risk to save a life, but we follow the Babylonian Talmud, which allows it and considers it a great mitzva. One exception would be if the donor risk exceeds the recipient's risk. Another exception would be certain cases, if the procedure has a <50% success rate: as long as the recipient could get off the operating table without this transplant, he's considered "presumed alive" and we try to save his life. But if, for instance, they've already taken out his heart and are about to put in a new one, he's no longer "presumed living", and thus we need 50+% chances. (This was R' Untermann's ruling regarding heart transplants from dead donors; the success rate has since exceeded 50%.) A last exception would be that as it's permitted but not required, if the donor's family objects or there's similar reason weighing against doing so. But basically if I understand the current numbers, all of these should be allowed.

As for donations from a dead body, we allow anything to be done to a dead body to save a life (see above caveats); the bigger concern is which organs get harvested before halachic death.

If I recall, Newsweek had a detailed description of a living-donor liver transplant, circa 2002. The recipient had damaged his liver from a youth full of drugs and alcohol, but had been clean for many years. I asked Rabbi Welcher if we factor into our decision whether the person in danger brought it upon himself like this case, he said probably not.

One issue dealt with by pos'kim is the prohibition against wounding oneself. Rabbi Moshe Feinstein in a letter reprinted in Igros Moshe (Choshen Mishpat Ⅰ 103) says that it is permissible to donate blood even though there is no known recipient now, in a case where the donor gets paid for his donation; part of his reasoning is that bloodletting, long thought to benefit the bloodlettee (or whatever the word is), probably does in fact benefit him, albeit slightly. Note that Rabbi Feinstein was dealing with the case he was presented (viz, where the donor is paid, etc.), and should not necessarily be construed as forbidding other cases. As always, CYLOR.

I saw the tshuva on donating blood for money recently (I think it's #103?). The Jewishness-of-the-recipient criterion doesn't appear there; that subject is hotly debated (Dr. Rosner quotes R' Moshe that it doesn't matter, others' stories seem to say otherwise). –  Shalom Oct 4 '10 at 20:08
    
With regards to donating blood R' Moshe doesn't employ the "pikuach nefesh" (save-a-life) argument, as there's no one right now going "help! Save my life!", and the blood may never even get used. I'm not sure that's the reality today (better screening, more procedures needing blood). Certainly with regards to a kidney, liver, or the like, there is a recipient right here, so it IS pikuach nefesh. –  Shalom Oct 4 '10 at 20:08
    
@Shalom, fixed the answer; thanks. –  msh210 Jun 17 '13 at 0:06

It is the opinion of a growing number that it is such a mitzvah to save a life that a person who is dead can donate any organs. Please see the Halakhic Organ Donation Society for more information.

The definition of halakhically "dead" is disputed - some see it as the complete cessation of the heart-beat and others the complete cessation of independent breath. The latter definition (aka, "brain stem death") is held by US and Israeli law and allows for more organs to save others' lives.

From that site:

Rabbi Moshe Feinstein also accepted brain-stem death as halachic death even though the person's heart was still beating. Another way to phrase his position is unconsciousness coupled with irreversable cessation of respiration (as confirmed by the death of the brain-stem) is death. He wrote his position in Iggrot Moshe, in a letter to Dr. Bundy and in his letter to Dr. Frank Veith (JAMA article, page 1654). Some have claimed his rulings in Igrot Moshe do not support brain death. Yet, in addition to his writings, every person who ever spoke with Rav Moshe Feinstein about this issue confirmed he accepted brain-stem death as death.

And:

The above prohibitions [Nivul Hamet, Halanat Hamet, and Hana’at Hamet] afford respect and dignity to cadavers, for they once hosted life itself. In this context, it makes sense that all Rabbis agree that saving a life outweighs observing prohibitions concerning a cadaver because by saving a life one is giving utmost respect and dignity to the human body. As it is written in Jewish Law, "Save one life and it is as if you have saved the entire world," Sanhedrin 4:5.

Much better IMO +1 –  Double AA Jul 11 '12 at 15:38
    
I don't see the relevance of the first quotation, which discusses not permissibility (or desirability) of organ donation but time of death. (And I believe the second quotation misquotes chazal, not that that's your fault.) –  msh210 Jul 11 '12 at 15:51
    
There are many organs that cannot be donated once the heart has stopped beating (e.g., heart, lungs) but may still be donated after brain-stem death. This allowance increases the number of organs that can be donated. –  Charles Koppelman Jul 11 '12 at 16:58
    
@msh210 Misquotes in a relevant way or just stam? –  Double AA Jul 11 '12 at 23:31
    
CharlesKoppelman, thanks for the info, and the more so for adding it into the answer. @DoubleAA, relevantly: the mishna says "everyone who establishes one life among the Jews is… like he saved a whole world"; if that mishna is the sole support for allowing organ donation then it should be allowed only to save a Jew. –  msh210 Jul 12 '12 at 4:15
