Visualization of the neurovascular bundles and major pelvic ganglion with fluorescent tracers after penile injection in the rat

FG injection into the penis has consistent retrograde staining of the NVBs and MPG after 3 days. Therefore, we predict that FG could potentially be used to improve the identification of the NVB in other models. However, further studies need to be carried out before these tracers can be used in humans.
