Abstract

Objective To determine matrix metalloproteinase 2 (MMP-2) levels in sera and peritoneal fluids of women with or without endometriosis-associated infertility and to determine whether MMP-2 had correlation with 17beta-E(2) and P in the sera and peritoneal fluids of the patients with endometriosis.Design A case-control study.Setting A women's hospital in China.Patient(s) Forty patients with endometriosis-associated infertility undergoing laparoscopy and 18 women undergoing tubal ligation.Intervention(s) Sera and peritoneal fluids were collected from women with or without endometriosis.Main outcome measure(s) Matrix metalloproteinase 2, 17beta-E(2), and P concentration.Result(s) Compared with the control women, the patients with endometriosis had higher MMP-2 levels in their sera and peritoneal fluids. Serum and peritoneal fluid MMP-2 levels were higher in the proliferative phase than in the secretory phase. The level of MMP-2 in the patients was correlated positively with 17beta-E(2) in serum and peritoneal fluid and negatively with P.Conclusion(s) The results demonstrated a correlation between MMP-2 concentrations and steroid hormones in sera and peritoneal fluids of the patients with endometriosis-associated infertility. Estradiol might up-regulate MMP-2, resulting in the formation of endometriosis. Progesterone might down-regulate MMP-2 to inhibit the formation and development of endometriosis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
