Table 5 The presence of detached germ cells into the lumen of seminiferous tubules is stage-dependent. Mean number of tubules with germ cells into the lumen 15 or 35 days after the lesion of the DRN (Mean ± S.E.M.)

From: Dorsal and medial raphe nuclei participate differentially in reproductive functions of the male rat
