ClinConnect Summary

This clinical trial is exploring how the microbiome—the community of microorganisms living in our bodies—affects the time it takes for women to become pregnant and the outcomes of their pregnancies. Researchers are specifically looking at women who have previously had at least one baby and are now planning to conceive again with the same partner.

To be eligible for this study, women need to be between 18 and 40 years old, have given birth in the last five years, and live in Sweden. Participants will be asked to provide samples to help the researchers study their microbiome and will complete a questionnaire online. This trial aims to better understand the role of microbial health in pregnancy, which could lead to improved support for women trying to conceive. If you meet the criteria and are interested, this could be a valuable opportunity to contribute to important research in fertility.
