Testicular interleukin-6 response to systemic inflammation.

Spermatogenesis is a highly controlled process of proliferation, meiosis, and differentiation. Systemic infection and chronic inflammation can impair testicular steroidogenesis and spermatogenesis. In this study, we examined the effect of systemic infection--intraperitoneal (i.

Interleukin-6 expression during normal maturation of the mouse testis.

In this study, we examined the cellular origin and the expression levels of interleukin-6 (IL-6) during normal maturation of mouse testis. The levels of IL-6 (protein and mRNA) were higher in testicular homogenates of sexually immature than mature mice. Immunohistochemical staining of testicular tissues of sexually immature and adult mice show that testicular germ cells, at different stages of differentiation, Leydig cells/interstitial cells and peritubular cells express IL-6.
