U.S., Oct. 1 -- ClinicalTrials.gov registry received information related to the study (NCT07848399) titled 'Endometrial Immune Profile in Recurrent Implantation Failure' on Sept. 21.
Brief Summary: The goal of this observational study is to learn whether differences in the immune cells of the womb lining (endometrium) help explain why some women do not become pregnant despite several IVF attempts using good-quality embryos, a condition known as recurrent implantation failure (RIF).
