Fig. 1From: Single injection of very mild dose botulinum toxin in the vastus lateralis improves testicular spermatogenesis and sperm motility in ageing experimental miceBoNT treatment improves sperm count and motility. Phase-contrast microscopic images of sperms obtained from the cauda epididymis of the control (A) and BoNT (B) treated animals. The bar graphs represent the total sperm count (C) and the percentage of total motility (D) and progressive motility (E) from the control and BoNT treated animalsBack to article page
