Euploid blastocyst rates in patients from POSEIDON groups 3 and 4 using propensity score matching

Abstract

Research questionDo patients with low ovarian reserve, as defined by the patient-oriented strategies encompassing individualized oocyte number (POSEIDON) criteria, have low euploid blastocyst rates? DesignRetrospective study of 548 IVF cycles of patients with unexplained recurrent miscarriage who underwent preimplantation genetic test for aneuploidy (PGT-A). Euploid blastocyst rates were analysed to compare patients from POSEIDON groups 3 and 4 (serum anti-Müllerian hormone [AMH] levels <1.2 ng/ml) with those who have normal ovarian reserve (AMH levels ≥1.2 ng/ml) before and after using propensity score matching to match selected variables, such as female age, body mass index, the number of clinical miscarriages, ovarian stimulation protocols and PGT-A analysis platforms. Cycles of patients from POSEIDON groups 3 and 4 were then divided into four groups according to median and quartiles of serum AMH levels: <0.668 ng/ml, 0.668–0.890 ng/ml, >0.890–1.070 ng/ml and >1.070–<1.20 ng/ml. The euploid blastocyst rates were compared across these four groups. ResultsAfter using propensity score matching, no difference was found in euploid blastocyst rates between patients from POSEIDON groups 3 and 4 and those with normal ovarian reserve. Among cycles of patients from POSEIDON groups 3 and 4, no difference was found in euploid blastocyst rates between the different AMH levels. ConclusionsThe decline in ovarian reserve in patients from POSEIDON groups 3 and 4 was not related to low euploid blastocyst rates. Serum AMH levels do not seem to be a predictor of euploid blastocyst rates in such patients.
