Fig. 4From: Single injection of very mild dose botulinum toxin in the vastus lateralis improves testicular spermatogenesis and sperm motility in ageing experimental miceBoNT treatment indicates increase of spermatogenesis. Light microscopic images of the H and E staining depicts the cross sections of the seminiferous tubules in the control (A) and BoNT treated animals (B). The bar graphs show the total number of primary spermatocytes (C), secondary spermatocytes (D), round spermatids (E), and elongated spermatids (F) per cross section of the seminiferous tubule in the testis of control and BoNT treated animalsBack to article page
