Official title
Impact of Endometrial Compaction in Euploid Frozen Embryo Transfers: a Prospective Observational Pilot Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this pilot study is to evaluate whether a decrease in endometrial thickness (compaction) prior to progesterone exposure (endogenous or exogenous) to the day before a single frozen embryo transfer has an impact on the clinical pregnancy rate with euploid embryos in exogenous hormone and modified natural thaw cycles. Information derived from this study may give insight on ways to improve pregnancy rates in cryo-thaw cycles.
