Researchers want to understand why some women struggle to get pregnant or have repeated miscarriages. This study compares immune cells in the uterine lining and bloodstream of women with fertility issues to women who have had successful pregnancies. By looking at these differences, scientists hope to find new ways to help women with infertility or recurrent miscarriage.
Many women experience infertility or repeated miscarriages without a clear medical reason. Scientists believe the immune system in the uterus may play a role, but we don't fully understand how. This research aims to identify immune cell differences that might explain these problems and lead to better treatments.

If you join, you will undergo a small uterine tissue biopsy (a sample taken with a thin tube) during a specific time in your menstrual cycle, and a 10 ml blood sample will be collected at the same visit. The tissue and blood samples will be analyzed in a laboratory to examine your immune cells. The entire process is part of your regular diagnostic care, and your medical history will be recorded to help researchers understand the results.
