The analysis included 160 patients who were randomly assigned to either group A or group B on the 7th day of oestradiol intake of their FET-HRT cycle. After the exclusion of drop-outs and screening failures, 144 patients were included either in group A (75 patients) or group B (69 patients) (Fig. Flowchart randomizationPatients’ demographic characteristics such as age, BMI, AMH, as well as smoking habits, parity, and indication for ART, are summarised in Table Baseline characteristicsEndometrial thickness was measured after 7 days of oestrogens supplementation for both groups A and B

Demographic characteristics for both groups were comparable. Notably, there was no significant difference in the parity of both groups. Most patients had undergone one or no previous ART cycles and had either one or no previous live births. Additionally, the indications for ART were evenly distributed between both groups. In the entire study population, the most frequent indications for ART were the idiopathic cause and male factor. There was no significant difference between E2 and P4 levels, as well as endometrial thickness measured on the day of ET.
