the stimulatory ( abp ) and inhibitory ( oestradiol ) effects of pachytene spermatocyte and early spermatid-spent media were reversible ( change of media ) , dose related , specific ( no effect of cytoplast , peritubular cell , rat liver epithelial cell or 3t3 cell-conditioned media ) and strictly proportional to the cell viability estimated at the end of the incubation periods .
