The macrophages in testis function

Spermatogenesis and steroidogenesis comprise the two essential functions of the testis. Consequently, the vast majority of research in this organ has focused in understanding how androgens are synthesized and released and what genes and factors control germ cell development. However, histological examination reveals that beside Leydig cells a considerable and diverse population of leukocytes resides in the testicular interstitial space of most, if not all species, including human, with macrophages constituting the largest subpopulation (Hutson, 1989; Hedger, 1997).
