Positive expression of proteases and their inhibitors was found more frequently in cases with low ASRM scores, whereas presence of CPP correlated significantly with absence of expression of TIMPs 1 and 2, indicating, first, that production of these enzymes is more active during the initial phases of the evolution of ovarian endometriosis, declining as fibrosis develops, and second, that expression of TIMPs seems to play a role in the development of CPP.
