Abstract

Abstract: Research question: Does an association exist between ovarian reserve, ovarian response and embryonic euploidy in female patients under age 35 years? Design: This was a retrospective analysis of intracytoplasmic sperm injection and preimplantation genetic testing for aneuploidies cycles among patients enrolled at Bahceci Fulya IVF Center between January 2016 and August 2019. A total of 133 patients in POSEIDON group 1 (suboptimal responder; female age <35 years, antral follicle count [AFC] ≥5, number of oocytes retrieved <10) (group A), 133 patients in POSEIDON group 3 (expected low responder; female age <35 years, AFC <5) (group B) and 323 in the non-low-prognosis group (female age <35 years, AFC ≥5 and number of oocytes retrieved >9) (group C) were included. Results: There was no significant difference in euploidy rate per embryo among the three groups (61.7% [145/235] for group A versus 53.5% [68/127] for group B versus 62% [625/1008] for group C; P = 0.13). The cancellation rate in cycles without a euploid blastocyst was significantly lower in group C than groups A and B (8.4% versus 12.8% and 16.5%; P = 0.034). Multivariate regression analysis indicated that the ovarian response group did not significantly affect the probability of obtaining a euploid embryo. Trophectoderm score 'C' (odds ratio 0.520, P = 0.007) and inner cell mass score 'C' (odds ratio 0.480, P < 0.001) were associated with a decreased probability of obtaining a euploid embryo. Conclusions: These results confirm that POSEIDON group 1 and group 3 and non-low-prognosis patients have different probabilities of euploid embryos being obtained per cycle. However, euploidy rates per embryo are not affected by the patient's ovarian reserve and response.
