Although parameters such as VI did not show differences in this study—possibly related to the sensitivity of the detection technique, the heterogeneity of the PCOS patient population, or sample size—the difference in blood flow patterns, together with elevated uterine artery resistance, points to an overall trend of poor blood flow perfusion in the uterine-endometrial complex.
Analysis of CD25 + and CD25 − B1a immunoglobulins showed a trend toward more N-less (and thus more germline like) sequences in the former (unpublished observations); however, this did not reach the level of significance and it will be necessary to examine antigen recognition rather than antibody structure to elucidate the origin of B1a continual signaling and CD25 expression.
