Popis: STUDY QUESTION Is there a serum progesterone (P) threshold on the day of embryo transfer (ET) in artificial endometrium preparation cycles below which the chances of ongoing pregnancy are reduced? SUMMARY ANSWER Serum P levels WHAT IS KNOWN ALREADY We previously found that serum P levels STUDY DESIGN, SIZE, DURATION This prospective cohort study was performed between September 2017 and November 2018 and enrolled 1205 patients scheduled for ET after an artificial endometrial preparation cycle with estradiol valerate and micronized vaginal P (MVP, 400 mg twice daily). PARTICIPANTS/MATERIALS, SETTING, METHODS Patients ≤50 years old with a triple-layer endometrium ≥6.5 mm underwent transfer of one or two blastocysts. A total of 1150 patients treated with own oocytes without preimplantation genetic testing for aneuploidies (PGT-A) (n = 184), own oocytes with PGT-A (n = 308) or donated oocytes (n = 658) were analyzed. The primary endpoint was the OPR beyond pregnancy week 12 based on serum P levels measured immediately before ET. MAIN RESULTS AND THE ROLE OF CHANCE Women with serum P levels LIMITATIONS, REASONS FOR CAUTION Only women with MVP were included. Extrapolation to other P administration forms needs to be validated. WIDER IMPLICATIONS OF THE FINDINGS This study identified the threshold of serum P as 8.8 ng/ml on the day of ET for artificial endometrial preparation cycles necessary to optimize outcomes, in cycles with own or donated oocytes. One-third of patients receiving MVP show inadequate levels of serum P that, in turn, impact the success of the ART cycle. Monitoring P levels in the mid-luteal phase is recommended when using MVP to adjust the doses according to the needs of the patient. STUDY FUNDING/COMPETING INTEREST(S) None. TRIAL REGISTRATION NUMBER NCT03272412.
