Background and Aims: Progesterone production of human cultured luteinizing granulosa cells was reported to be modified by extracellular matrix, suggesting that extracellular matrix regulates luteinization of granulosa cells after ovulation. In the present study, the relationship among laminin, fibronectin, progesterone and estradiol in follicular fluid along with oocyte quality was analyzed to estimate the physiological role of extracellular matrix in follicular luteinization and oocyte quality during ovulation. Methods and Results: Follicular fluid was collected at oocyte pick-up from the patients undergoing in vitro fertilization treatment and intracytoplasmic sperm injection. The concentrations of laminin, fibronectin, progesterone and estradiol in the follicular fluid were measured by enzyme immunoassay and radioimmunoassay. The morphology of oocytes were also assessed during the procedure of intracytoplasmic sperm injection and was classified into normal and abnormal groups. The fibronectin concentration was higher in the normal ooplasm group than in the abnormal group, but it did not correlate with estradiol or progesterone concentration. However, laminin concentration significantly correlated with that of progesterone, but not with cytoplasm morphology of oocytes. There was no difference in estradiol or progesterone concentration between the normal and abnormal groups. Conclusion: These findings suggest that extracellular matrix plays some roles in regulating human granulosa cell luteinization and oocyte quality during ovulation.
