Infertility patients caught in the legal, moral and scientific embryo debate

Finally, she and her husband, Cheddi, conceived a daughter, now 3, through in vitro fertilization. About a year later, she became pregnant with a second child, naturally. Their family was complete.

Then, a year ago, the Fountain Valley couple received a bill reminding them that their infertility journey wasn't quite over. They owed $750 to preserve three frozen embryos they'd created but hadn't used.

"I don't see them as not being life yet," says Gina Rathan, 42, a pharmaceutical sales representative. "I thought, 'How can I discard them when I have a beautiful child from that IVF cycle?' "

Many other former infertility patients also appear to be grappling over the fate of embryos they have no plans to use: An estimated 500,000 embryos are in cryopreservation in the United States.

As with the Rathans, this unexpected conundrum often arises well after the infertility crisis has passed, triggering impassioned and highly personal debates about the science and ethics of human life. The discussion boils down to a fundamental question: What is this icy clump of cells smaller than a grain of sand?

Across the country, people with less personal stakes in the matter are asking that question as well.

Colorado voters will decide in November whether to amend the state's constitution to assert that an embryo is a person. Indiana lawmakers have proposed legislation that would allow abandoned embryos to be adopted for implantation by another couple. New Jersey legislators have moved to allow unused embryos to become wards of the state. And Georgia and West Virginia are considering legislation that would give embryos "personhood" status.

Although these proposals are sponsored in large part by abortion opponents, infertility patients nationwide -- whose feelings about abortion run the gamut -- are finding themselves ensnared in a debate about when life begins.

"They are in the middle of this ideological war, although they may not be aware they are in the middle of a war," says Renee Whitley, co-chairwoman of the national advocacy committee for Resolve, an organization supporting people with infertility. "This is the politics of embryos."
