Immunolocalization of androgen receptors in early and immature testis of Anguilla anguilla (L.)
The first androgen receptors (AR) immunolocalization in yellow eels occurs in the early Syrski organ. At this stage, the AR immunoreactivity is detected in pre-Leydig cells and in pre-Sertoli cells, but not in germ cells. In early testis the AR immunoreactivity appears in Leydig and Sertoli cells.
