Cadmium-induced impairment of spermatozoa development by reducing exosomal-MVBs secretion: a novel pathway
Figure 6. Electron micrograph of spermatozoa of control (A) and cadmium treated (B) group. (A) Healthy spermatozoa were observed in luminal compartment of seminiferous tubules. (B) Destructive spermatozoa were observed in luminal compartment of seminiferous tubules. Sp: spermatozoa; Sh: sperm head; Mp: mid-peace; N: nucleus; Ac: acrosome reaction; M: mitochondria; (arrow head) exosome; (arrow) axonema; (curved arrow) vacuolation. Scale bars 5 μm.
