Neuropeptide Y (NPY) was found in high concentrations in the male genital tract. NPY levels were highest in the seminal vesicles, prostate, corpus cavernosum and vas deferens, where large numbers of immunoreactive nerve fibres were detected. Considerable quantities were also found in the epididymis and spongiosum. Lower concentrations were found in the glans penis, testis and foreskin. The presence of a large number of nerves containing NPY suggest that this active neuropeptide may play a role in control of genital function.
