About this trial
Capacitation in vitro maturation (CAPA-IVM) has improved oocyte maturation and resulted in live births. Because cumulus cells (CCs) communicate bidirectionally with the oocyte, their transcriptomic profile may serve as a non-invasive biomarker of oocyte and embryo competence. This prospective pilot study will analyze CCs gene expression after CAPA-IVM using RNA sequencing and pathway analysis, and correlate findings with embryological outcomes including fertilization, day-3 cleavage, and blastocyst formation. Results are expected to provide insights into the molecular basis of oocyte competence and support development of non-invasive embryo selection strategies.

Trial outcomes
Primary outcomes
Correlation of cumulus cell transcriptomic profiles with embryological outcomes
Association between cumulus cell gene expression (RNA-seq-based transcriptomic profiles) and embryological outcomes, including cleavage and embryo quality (Day 3), and blastocyst formation and grading (Days 5-6).
Secondary outcomes
CCs transcriptomic profiles
RNA sequencing of CCs collected from individual COCs after CAPA-IVM. Differential gene expression will be analyzed using DESeq2, followed by Gene Ontology enrichment and Ingenuity Pathway Analysis to identify pathways, molecular functions, and regulatory networks associated with oocyte competence.
Number of matured oocyte
The number of oocytes that have first polar body after denudation
Number of normal fertilized oocytes
Oocytes that show the presence of two pronuclei
Number of day-3 embryos
Day-3 embryo morphology assessed according to the Istanbul Consensus (2011), with reference to the revised criteria (2024)
