The Waterkooler

• John Opitz, a professor of pediatrics, human genetics, and obstetrics and gynecology at the University of Utah, testified before the President's Council on Bioethics that between 60 and 80 percent of all naturally conceived embryos are simply flushed out in women's normal menstrual flows unnoticed. This is not miscarriage we're talking about. The women and their husbands or partners never even know that conception has taken place; the embryos disappear from their wombs in their menstrual flows.
  
  
• If every embryo is "already a human being," does that mean that if we could detect such unimplanted embryos as they leave the womb, we would have a duty to rescue them and try to implant them anyway?
  
  
• Try this thought experiment. A fire breaks out in a fertility clinic and you have a choice: You can save a three-year-old child or a Petri dish containing 10 seven-day old embryos. Which do you choose to rescue?
  
  
• If embryos have a soul, that would mean that more than 40 percent of all the residents of Heaven were never born, never developed brains, and never had thoughts, emotions, experiences, hopes, dreams, or desires.
  
  

Millions of intelligent people of good will maintain that seven-day-old embryos have the exact same moral standing as do readers of this column. Acting on this sincere belief, they are trying to block biomedical research on human embryonic stem cells that is desired by millions of their fellow citizens.

But there may be a way out of this politico-theological impasse. The President's Council on Bioethics held an extraordinarily interesting session earlier this month in which two different avenues for obtaining human embryonic stem cells were proposed, in ways that would skirt right-to-life moral objections.

• William Hurlbut, a consulting professor in the Program of Human Biology at Stanford University and another member of the President's Council on Bioethics, proposed another way to produce cloned human embryonic stem cells that right-to-lifers should not find morally objectionable.
  
  
• "This process does not involve the creation of an embryo that is then altered to transform it into a non-embryonic entity," explained Hurlbut. "Rather the proposed genetic alteration is accomplished ab initio, the entity is brought into existence with a genetic structure insufficient to generate a human embryo."
  
  
• These options offer a possible way around the moral blockades that impede promising biomedical research on human embryonic stem cells.
