Why this matters:
Roughly 6.1 million women in the U.S. have trouble getting or staying pregnant. Many never find out why.
Recent research has identified a genetic pattern in the uterine lining that could provide information that increases the chances for a successful pregnancy.
Understanding this gene series could lead to better diagnostic tests and treatment options for people who are struggling to get pregnant.
Even in the best fertility clinics, transferring a healthy embryo into the uterus leads to a live birth only about half the time. In 30% to 35% of cases, the embryo does not implant at all. Other times, implantation happens but the pregnancy ends in miscarriage.
