Trouble getting pregnant and future heart and metabolic health

Impaired fecundity and future health: a prospective investigation of pregnancy planners in North America and Denmark

NIH-funded research Stanford University · NIH-11318960

This project follows couples who are trying to conceive to learn whether difficulty achieving pregnancy is linked to higher risk of heart disease, diabetes, and other long-term health problems.

What this research studies

If you are planning a pregnancy, researchers combine two large groups of pregnancy planners in Denmark, the U.S., and Canada and follow both partners over time. Participants complete regular online questionnaires about reproductive history, lifestyle, and health, and where available the study uses biological markers and medical data to track outcomes. The combined cohorts include more than 39,000 people and allow comparison between those who conceive quickly and those who experience impaired fecundity. The team will examine whether early reproductive problems precede higher rates of cardiometabolic and other diseases later in life.

Who could benefit from this research

Good fit: Ideal candidates are adults in the U.S., Canada, or Denmark who are actively planning pregnancy and willing to complete online follow-up and share health information.

Not a fit: People who are not planning pregnancy, already pregnant, or living outside the U.S., Canada, or Denmark are unlikely to be eligible or benefit from participating.

Why it matters

Potential benefit: If successful, this work could help clinicians recognize fertility problems as an early warning sign and guide earlier screening or prevention for heart and metabolic disease.

How similar studies have performed: Earlier retrospective studies have linked infertility to later cardiometabolic disease, but large prospective cohorts like these are newer and provide stronger, more reliable evidence.
