PURPOSE: To assess levels of matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9) in follicular fluids and sera of female patients undergoing in vitro fertilization (IVF) treatment, and discover the role of MMPs in IVF outcome prediction. METHODS: Sera and follicular fluids were obtained from 58 female patients treated for infertility by IVF. Twenty-nine of them became pregnant after the embryo-transfer; another 29 were not successful in IVF and did not conceive. Forty female non-pregnant blood donors and 38 healthy pregnant patients in the first trimester after the physiological conception were examined as control groups. MMP-2 and MMP-9 were quantitively assessed using enzyme-linked immunosorbent assay. RESULTS: IVF females successfully conceiving after the IVF have shown the highest MMP-9 concentrations in sera (833.5 {686.0;958.7} ng/mL) and follicular fluids (9.6 {6.0; 17.0} ng/mL) compared to all other examined cohorts. Different behavior of MMP-2 and MMP-9 during the artificial ovulation was confirmed, because only MMP-9 has shown a vast difference between serum and follicular concentrations. CONCLUSIONS: MMP-9 could be a good predictor of the successful IVF outcome (pregnancy), which was proven for serum as well as follicular MMP-9 levels.
