By all accounts, graduate student Jessica Grace Wing was the ideal egg donor. At 5 feet 11 inches, she was tall, slender and attractive. She modeled in her teenage years and would go on to graduate from Stanford University. This made her an ideal donor, "the kind of donor that would attract a great deal of money," her mother, Dr. Jennifer Schneider, said.
But seven years after she was paid to donate her eggs, Jessica was diagnosed with colon cancer, at the age of 29. She died two years later. Hers was a rare diagnosis for someone so young and something Jessica's biological children will never know, despite Jessica's mother's attempts to contact the broker who sold her daughter's eggs.
But when Schneider asked the egg donation broker to reveal the identities of the families who had received the eggs, the broker said she had destroyed her records. Jessica donated her eggs three times.
"At the time she died, I tried to get hold of the [in vitro fertilization] clinics. The egg broker and I couldn't get hold of anybody," Schneider said. "Nobody was interested in talking to me, and I understand why.
"The conflict of interest is the financial interest versus the welfare of the donor and of the children who are born," she said. "I think it's very hard for people to regulate themselves when there are billions and billions of dollars involved."
Colon cancer can be inherited. Because Wing was diagnosed at the age of 29, her biological children, Schneider said, should start getting colonoscopies at the age of 19. Schneider points out that very few families would think to have their children receive colonoscopies in their teens or 20s.
In addition to the families, Schneider also worries about the welfare of other women who are egg donors. She is concerned that the fertility drugs used to help her daughter produce eggs may have contributed to her cancer, and she wants studies done on other women who have also donated eggs and may have ended up with an early cancer diagnosis.
"My daughter Jessica was an egg donor when she was in college, and a few years later, she was dead of colon cancer," Schneider said. "It got me on this path of trying to find out of there's a connection between egg donation and colon cancer."
But while donors are screened carefully, there is little to follow up with later on. No one is keeping track of these egg donations and no one is monitoring all of the donors' health histories.
Wing's case sheds light on the delicate questions surrounding sperm and egg donation. How much information should donors be required to reveal? Where does the donor's right to privacy end and the child's right to know begin?
"The forgotten people in this whole big business [are] the egg donor and the children," Schneider said.
Part of the problem, however, is that many people donate on the condition of anonymity.
Dr. David Adamson, president of the American Society of Reproductive Medicine, said, "One thing we know is that if we make it too intrusive people will not have access to these services because donors will not come forward."
William Jaeger, vice president of Fairfax Cryobank in Virginia, said his company offers an identification consent donor program that allows a child born of donor sperm to contact the donor once he or she reaches the age of 18. But the number of people using that option is still only about 20 percent, he said.
