Endometriosis, which is common in women of reproductive age, may affect fertility. It is also clear that mechanical disruption of the pelvic anatomy may cause infertility. However, our understanding of the association between the early stage of endometriosis and infertility remains incomplete. Bloody peritoneal fluid (PF) is frequently observed in the cul-de-sac of endometriosis patients and contains various biologically active factors. We found that the concentrations of tumor necrosis factor alpha (TNF-alpha) and interleukin-6 (IL-6) in PF from patients with endometriosis were significantly higher than that of patients with endometriosis. There were significantly positive correlations between the levels of TNF-alpha and IL-6. We compared the levels of these cytokines with regard to the R-AFS stages and scores, but no differences were observed. In contrast, these cytokines correlate with the number and extent of red color peritoneal endometriosis. TNF-alpha increased the expression of IL-6 messenger RNA and protein in endometriotic stromal cells derived from chocolate cyst in a dose-dependent manner. The addition of IL-6 inhibited the development of mouse preimplantation embryo and impaired sperm function. We concluded that increased levels of IL-6 in peritoneal fluid of patients with active red endometriosis might be related to endometriosis-associated fertility.

Esculentoside A (EsA) is a saponin isolated from the roots of Phytolacca esculenta. Previous experiments have shown that it has strong anti-inflammatory effects. Tumour necrosis factor (TNF) is a very important inflammatory mediator. It is known that there are two types of TNF-TNFalpha is from macrophages/monocytes and TNFbeta is from activated lymphocytes. In order to study the mechanism of the anti-inflammatory effect of EsA, it was determined whether TNFalpha production from human peripheral monocytes was altered by EsA under lipopolysaccharide (LPS)-stimulated conditions. EsA was found to decrease TNFalpha production in a dose-dependent manner at concentrations higher than 1 mumol/l EsA. Recent studies have shown that EsA has a curative effect on chocolate cyst and other inflammatory diseases. Our previous studies have shown that EsA could reduce the release of platelet activating factor (PAF) from rat macrophages, and inhibit interleukin-1 and interleukin-6 production from routine macrophages. The reducing effects of EsA on the release of TNFalpha, IL-1, IL-6 and PAF may explain its anti-inflammatory effect.
