their partners in four US cities to look for differences between cities in several measures
of reproductive health. These measures include how long it took couples to conceive as well
as hormone levels and semen quality in the male partners. This study is modeled after a
study in four European cities so that,when complete, data on the 300 couples in each of the
eight cities can be compared.
Pregnant women and their partners who are literate in English or Spanish and competent to
complete a questionnaire whose pregnancy was conceived without medical intervention.
