Problem  To analyze the relation of the fertility and pregnancy of women of childbearing age to the intracellular (IC) production of tumor necrosis factor alpha (TNF-α), interferon gamma (IFN-γ), and interleukins 2 and 4 (IL-2 and IL-4).

Method of study  Intracellular cytokine production in peripheral blood CD3+ CD4+ lymphocytes was analyzed by flow cytometry in 185 women being treated for infertility and 50 fertile women of childbearing age.

Results  Infertile women have a significantly higher IC production of TNF-α, IFN-γ, IL-2, and IL-4 and higher ratios of TNF-α/IL-2, TNF-α/IL-4, and TNF-α/IFN-γ compared to the fertile women.

Conclusion  Cytokines produced by Th lymphocytes are important in orchestrating the immune response during conception, and Th-cell dysregulation could be a reason for infertility.
