Besides the pathological anti-sperm humoral immunity, pathological anti-sperm cell-mediated immunity is considered as a crucial facet of the disturbances of human reproduction (male and female infertility, recurrent abortions, endometriosis, late EPH gestosis, fetal hypotrophy). A precise and objective method is designed, based on a one-step agarose Leukocyte Migration Inhibition Factor assay. The migration areas are evaluated by a computer-assisted image analysis system. Optimal concentrations of leukocytes and sperm, as well as technical conditions are described. The Radius Migration Indexes and Area Migration Indexes are computed and expressed as a Migration Index percentage for each patient or control. Preliminary clinical results indicate a highly significant association between leukocyte migration inhibition and cases of "immunopathological" infertility and repeated fetal loss.

Idiopathic granulomatous orchitis (IGO) is a rare inflammatory disorder of unknown etiology affecting the testis. Presented here is the case of a young patient who developed IGO, potentially associated with an anti-sperm antibody-mediated autoimmune response.

Sialic acids are negatively charged carbohydrates that are components of saccharide chains covalently linked to macromolecules. Sialylated glycoproteins are important for most biological processes, including reproduction, where they are associated with spermatogenesis, sperm motility, immune responses, and fertilization. Changes in the glycoprotein profile or sialylation in glycoproteins are likely to affect the quality of ejaculate.

Regulatory T-cells (Tregs) are immunosuppressive T-cells, which arrest immune responses to 'Self' tissues. Some immunosuppressive Tregs that recognize seminal epitopes suppress immune responses to the proteins in semen, in both men and women. We postulated that GBMs express reproductive-associated proteins to manipulate reproductive Tregs and to gain immune privilege.
