Description
Yakup Bayram and colleagues tested in 2026 whether an egg maturity score predicts fertility treatment success in patients with low ovarian reserve. The Oocyte Maturation Index states the share of eggs that reach maturity. Their records covered 662 patients treated at a Turkish university unit between 2016 and 2024, split into younger and older low-reserve groups.
Egg and embryo counts differed clearly across the score bands in both groups. Among younger patients, the middle band, fifty-one to seventy-five percent, won the best pregnancy and live birth rates. The lowest band fared worst by a wide margin. In older patients the score still shifted early pregnancy rates but not live birth, which age-related egg problems may override. The authors recommend folding the index into routine assessment for personal planning and honest counseling.
