title: Role of cytokines in the regulation of reproductive function.
abstract: The levels of 17 cytokines in the follicular fluid were measured by multiplex proteome analysis at the peak of stimulated ovulation during the in vitro fertilization cycle. In patients with ineffective folliculogenesis, the concentrations of IL-2, IL-4, IL-7, and granulocytic CSF in the follicular fluid were significantly lower than in women with greater mean number of collected oocytes. It was shown that multicomponent cytokine deficit was associated with lower production of high quality oocytes and lower efficiency of fertilization of the resultant oocytes in vitro. The absence of pregnancy after in vitro fertilization cycle is associated with lower levels of IL-2, IL-4, IL-7, granulocytic CSF, and macrophagic inflammatory protein 1b in combination with elevated contents of IL-8 and IL-13. The results attest to an important role of cytokines in the regulation of oogenesis and in preparation of the endometrium to implantation of the embryo.
