Do girls and boys differ before birth? Seeking pregnant women for a study

Pregnant women are needed to participate in a longitudinal research study from late pregnancy until the baby is 6 months old. The first visit will occur between 35 and 38 weeks of pregnancy. After the baby is born, additional visits will occur when the baby is 3 and 6 months old. The study includes noninvasive monitoring of fetal heart rate and movement, cord blood sampling at birth, saliva samples from you and your baby, and measures of your baby's behavior as an infant. There are no known risks of participation for you or your baby. Compensation will be provided.

If you are interested in participating, contact the study research coordinator, Ashley Hucht, at ahucht1@jhmi.edu, 410-955-4682>.
