BUFFALO, N.Y. -- Researchers at the University at Buffalo and the University of Utah are beginning a clinical trial to test whether aspirin can improve a woman's chances of becoming pregnant and of maintaining a pregnancy to term.

UB's portion of the study is funded by a $2.8 million grant from the National Institute of Child Health and Development.

The trial is aimed at women who have miscarried a pregnancy in the past year.

"In women who have had their first miscarriage, the reasons for losing that pregnancy are in many instances unknown," said Jean Wactawski-Wende, Ph.D., UB associate professor of social and preventive medicine and principal investigator of the UB clinical center.

"These women generally are advised to try to get pregnant again, but health-care providers can offer limited assistance on any specific actions to take to improve their next pregnancy outcome," she noted. "If aspirin can help some women become pregnant or maintain a health pregnancy, it will be a critically important finding.

"Aspirin is available, inexpensive and has very few side effects," she added. "We're hopeful that this trial could produce an important finding."

Statistics show that in the United States, 10-15 percent of couples trying to become pregnant are not able to conceive, 15-31 percent of pregnancies that do occur end in miscarriage, and 8-15 percent of pregnancies that continue beyond 20 weeks end in premature birth, putting these infants at risk for increased health problems.

Aspirin has been shown to have beneficial effects in humans, said Wactawski-Wende. "It is an anticoagulant and an anti-inflammatory agent. It may aid in implantation of the egg in the uterine wall, and has potential for producing a positive effect on blood flow to the placenta. It may aid in reducing preeclampsia. This clinical trial provides an opportunity to determine the impact of low-dose aspirin on many pregnancy outcomes."
