Stem Cell Research Chain Larded With Cash Except for Women Egg Donors

The Wall Street Journal this morning carried an interesting piece on the risk, pain and money involved in the fertility and egg business.

Written by reporter Sylvia Pagan Westphal, the article offers some perspective on the research and economic issues involved in providing eggs for stem cell research – a subject of current interest in the California legislature and with the California stem cell agency.

Here are the first three paragraphs of the article:
"Nichola Grant underwent five in-vitro fertilization attempts the traditional way. First came weeks of daily hormone shots to stimulate egg production, which painfully bloated her ovaries and stomach. Then doctors inserted a needle through her vaginal wall to remove the eggs -- up to 20 at a time, she says -- from her ovaries. On three occasions fertilized eggs were put back in her womb but failed to lead to a baby.

"That was enough discomfort for Ms. Grant, a 34-year-old nurse in Queens, N.Y. She went to Manhattan fertility doctor John Zhang. There were barely any shots -- mostly pills -- and he removed just three eggs. He implanted one in the womb, and she delivered a baby boy in January. 'It was so easy,' she says. 'It's no comparison.'

"Dr. Zhang doesn't claim his method leads to higher pregnancy rates, but he does assert that Ms. Grant's story represents what's wrong with standard operating procedure at fertility clinics. He says the fertility profession is too concerned with drawing lots of eggs from women. The result, he believes, is more pain, a higher risk of complications and a success rate little improved over gentler approaches."
Westphal's piece continues: "'A lot of people realize we're overdoing it,' adds George Inge, a doctor at the Center for Reproductive Medicine in Mobile, Ala. 'We've got to come out with ways so women are not so beat down.'"

The story reports that the IVF business runs about $3 billion a year, according to Debora Spar, a Harvard Business School professor. More than 120,000 women underwent IVF procedures in 2003.

As for the risk of the procedure, the Journal says:
"One of the most serious complications is ovarian hyperstimulation syndrome, or OHSS, a potentially fatal condition in which ovarian tissue leaks fluid into the body cavity. This makes the blood thicker and increases the risk of stroke. Mild OHSS, which brings discomfort but doesn't require hospitalization, occurs in up to 35% of IVF cycles. Moderate to severe forms take place in up to 6% of cycles."
The piece cited the case of one woman who was admitted to a hospital where doctors drained seven liters of fluid over two days from from her abdominal cavity with a needle. Other sources have cited two deaths in the UK.

One of the working assumptions of stem cell researchers is that IVF will provide a lot of eggs that could be used for science. However, should Zhang's procedures become the market standard, that source would dry up. Which brings us to the question of whether women should be allowed to sell their eggs.

At every stage of the egg gathering process, money is being made except by the woman, who provides the critical material, if we are to follow the CIRM model. The clinics, even nonprofit ones, that extract the eggs maintain a margin in excess of costs. Doctors and nurses and other staff at the clinics earn their livings by harvesting eggs. The eggs then are provided to scientists to perform research. The scientists make their living doing this, receiving grants, being paid salaries, possibly enjoying revenues from inventions that require the use of a woman's eggs. The research institutions' coffers and reputations are enriched as well by the stem cell research that requires the use of eggs from a woman who receives no payment. The commercial enterprises that bring the therapies to market stand to make huge sums based on material that has been derived at no cost from a woman, who may or may not know that at the time of donation that a host of people and enterprises stand to gain economically from her donation.

Prop. 71 bars compensation for eggs, and CIRM has approved rules to ensure that women know some of the economic implications of their donations. But they are unlikely to tell donors that the research chain is larded with folks who will make money on something that they are giving away.

Somehow it doesn't seem quite fair.
