Abstract

fetched live from OpenAlex

BACKGROUND: The aim of this study was to investigate whether in vitro maturation (IVM) and blastocyst development of oocytes collected following HCG-primed IVM cycles of PCOS patients are correlated with their cumulus cell (CC) patterns and further to investigate mRNA expression of the receptors for FSH, LH and epidermal growth factor (EGF) in the CCs with each pattern. METHODS: Patients who underwent IVM were primed with 10,000 IU of HCG 36 h before oocyte aspiration. The isolated cumulus-oocyte complexes were divided into three groups according to the CC patterns: oocytes with dispersed CCs (group A), oocytes with compacted CCs (group B) and oocytes with sparse CCs (group C). Oocyte maturation and blastocyst development were compared among three groups. The expression of the mRNA for FSH, LH and EGF receptors in group A and B was analysed by semi-quantitative RT-PCR. RESULTS: The maturation rate of group A was significantly higher than those of group B and C. The rate of blastocysts in group A was significantly higher than those of group B and C. mRNA expression of the LH receptor in group A was more abundant than that of group B. CONCLUSIONS: These results suggest that the presence of dispersed CCs at oocyte collection may be positively correlated with the rates of oocyte maturation and blastocysts in HCG-primed IVM cycles. In addition, the expression of LH receptor in CCs may be correlated with the CC pattern of oocytes at collection.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
