Back to TTM ResultsBy the first lab visit, which was about 6 months of marriage, 7% of the couples were expecting children. By the end of the study, 22% of the couples had had at least one child. Of course, some of the couples in the project dropped out, and we do not have information on whether they went on to have children. In other similar studies of newlywed couples in the U.S., couples begin having children about 2.5 years into their marriage. We only followed couples for about 2.5 years, so it is likely that many more couples from the project have gone on to have babies since the study ended.
