Features of the state of cytokine status in infertile men against the background of toxocariasis by L. L. Vorontsova, M. I. Dub, V. A. Kovalenko, M. Ye. Zhuravlova

“…Thus, in infertile men against the background of toxocariasis, the triggering mechanism of stimulation of the Th2 type immune response are obviously the components of the shell of the parasite larvae which were invaded in host organism, and the attachment of the Th1 type immune response leads to the formation of the chronic process (chronic invasion), which adversely affects the development of an adequate immune response.…”
