研究问题
However, these features do not necessarily mean that the oocyte has acquired the cytoplasmic functions required for fertilization and early embryogenesis [, ].；This gap between visible maturity and functional competence limits routine laboratory assessment.
方法
Available human follow-up data are generally reassuring but remain incomplete: meta-analytic and observational studies have not shown a significant increase in major birth defects after ICSI-AOA, and early-childhood neurodevelopmental follow-up has not identified obvious adverse signals [, ].；However, congenital-anomaly reporting in randomized trials remains limited, long-term offspring follow-up is still sparse, and small recent epigenetic or neonatal-outcome studies cannot exclude rare or delayed effects [, , ].；Thus, AOA should be regarded as an indication-guided intervention requiring informed counseling and continued follow-up, rather than as a risk-free extension of routine ICSI.
核心结论
This distinction is clinically relevant in assisted reproductive technology (ART), because in vitro matured oocytes and morphologically mature oocytes may still show reduced fertilization or developmental competence compared with oocytes matured under more physiological conditions [–].；Fertilization failure after IVF or ICSI illustrates the same problem from a functional perspective: an apparently mature oocyte may fail to activate, form pronuclei, or support early embryo development despite acceptable routine morphology [].；In mammalian oocytes, this maturation-associated competence is closely associated with coordinated changes in ER organization, ER Ca2+ stores, and the abundance and responsiveness of inositol 1,4,5-trisphosphate receptor type 1 (IP3R1) [, ]. ‖ 结论：Future studies that connect ER-associated cytoplasmic organization with patient context and developmental endpoints may improve the biological interpretation of oocyte quality and support more refined assessment strategies in ART.
