Decline in ethical concerns about reproductive technologies among a representative sample of US women.

Public awareness and utilization of assisted reproductive technology has been increasing, but little is known about changes in ethical concerns over time. The National Survey of Fertility Barriers, a national, probability-based sample of US women, asked 2031 women the same set of questions about ethical concerns regarding six reproductive technologies on two separate occasions approximately 3 years apart. At Wave 1 (2004-2007), women had more concerns about treatments entailing the involvement of a third party than about treatments that did not.
