Fig. 3From: Single injection of very mild dose botulinum toxin in the vastus lateralis improves testicular spermatogenesis and sperm motility in ageing experimental miceNo major structural difference in the seminiferous tubules between control and BoNT treated animals. The H and E staining represents the morphology of seminiferous tubules in the testis of control (A) and BoNT treated animals (B). The bar graph data represents the diameter of seminiferous tubules (C), the diameter of lumen of seminiferous tubules (D)Back to article page
