Association of interleukin-1beta C?+?3953T gene polymorphism with human male infertility

Cytokines are involved in the regulation of spermatogenesis likely mediating the crosstalk among Sertoli and germ cells to facilitate germ cell movement across the seminiferous epithelium during cellular events such as germ cell differentiation. Members of the Interleukin-1 (IL-1) family are pleiotropic cytokines that are involved in inflammation, immunoregulation, and other homeostatic functions. Interleukin-1 alpha (IL-1α), IL-1β, and the IL-1 antagonistic molecule (IL-1 Ra) are present in the testis under normal homeostasis and they further increase upon infection/inflammation. In the present study we have examined the association of C + 3953T polymorphism of the human IL-1B gene with human male infertility. The case control study comprised of two groups: 222 infertile patients and 230 fertile healthy control men. Genotyping for SNP C + 3953T IL-1B was carried out by polymerase chain reaction followed by analysis with specific endonucleases (PCR-RFLP). DNA sequencing was used to validate the PCR-RFLP results. The genotype frequencies of the IL-1B Taq C/T polymorphism were compared between infertile men and controls. The frequency was significantly higher in asthenozoospermic patients compared to fertile control men (odds ratio = 10.4, CI: 2.50- 43.96, p = 0.001). The C + 3953T of the IL-1B gene is associated with male infertility risk in the asthenozoospermic patients from an Indian population.
