The aim of this study was to investigate the effect of human hydrosalpinx fluid (HF) on the development and blastulation of mouse embryos and the role of the concentration of growth factors in culture medium with and without HF. In total, 2100 mouse embryos were cultured. Female mice were induced to superovulate and then mated with males. Two-cell-stage embryos were recovered from the oviduct and cultured in Ham's F-10 medium with bovine serum albumin and HF. Epidermal growth factor (EGF) and insulin-like growth factor-I (IGF-I) were analyzed by quantitative enzyme immunoassay. Mean blastulation index of 1.11, 0.97 and 0.98 was found at HF concentration of 5%, 20% and 30%, respectively (p = 0.8). The mean value of EGF in the control culture medium without HF was 11.2 pg/ml, which was statistically significantly different from that in culture medium containing HF (p < 0.001). The mean value of IGF-I in the control group without HF was 1.30 pg/ml and was not statistically significantly different from that in culture medium containing HF. Development of the two-cell-stage embryos was not affected at low (< 30%) HF concentrations. In conclusion, the present study demonstrates that even apparently normal blastulation is affected by any concentration of HF because of low embryonic EGF.

The aim of this study was to determine whether differences in cytokine concentrations, chemical composition, and murine embryogenesis in hydrosalpinx fluid could be observed between women with hydrosalpinx who achieved and did not achieve pregnancy.. Hydrosalpinx fluids were collected from 39 infertile women participating in an IVF-embryo transfer programme at a university teaching hospital. The fluids were analysed for concentrations of cytokine concentration (epidermal growth factor, interferon-gamma, leukaemia inhibitory factor, and tumour necrosis factor-alpha) and chemical composition. Mouse embryos were cultured in medium with various concentrations (0, 10, 50, 100%) of hydrosalpinx fluid.. Logistic regression demonstrated that a murine blastocyst formation rate >or=53.3% in 50% hydrosalpinx fluid (OR = 16.6, 95% CI 2.4-116.1, P = 0.005) and patient age (OR = 0.778, 95% CI 0.61-0.99, P = 0.045) were independent predictors of IVF outcome. The diagnostic accuracy did not significantly improve when age and number of good quality embryos transferred was taken into account. The chemical composition and cytokine concentrations of hydrosalpinx fluid were not predictive of subsequent IVF outcome.. The mouse embryo assay of hydrosalpinx fluid might potentially serve as a predictor of subsequent IVF outcome in women with hydrosalpinx. This technique may be useful in selecting appropriate treatment options for patients with hydrosalpinx undergoing IVF treatment.
