What this trial studies

This observational study aims to identify and correlate biochemical markers that reflect the window of implantation (WOI) during the midluteal phase of the menstrual cycle. Participants aged 20-40 will undergo endometrial biopsy and blood sampling at specific time points, including pre-conception and during pregnancy. The goal is to establish reliable clinical and biochemical indicators of WOI, which is crucial for successful implantation and pregnancy outcomes.
