Briefly, the authors found that, for certain kinds of

directly into the uterus resulted in more pregnancies than did
several similar techniques. "The demand for effective
infertility treatments is high and this frequently leads to use
of therapies that haven't been tested by clinical trials," said
NICHD Director Duane Alexander. "This rigorous evaluation--
perhaps the most comprehensive of its kind--will provide
invaluable information for those who need it most." The research
team was composed of scientists in NICHD's National Cooperative
Reproductive Medicine Network, and the study's first author was
David S. Guzick, MD, PhD,of the University of Rochester, in
