Summary
The distribution and relative density of peptide-containing nerves was studied in the rat in order to assess the progression of neuronal changes during the postnatal development of the male genital system from the prepubertal age to adulthood. Testis, caput and cauda epididymis, ductus deferens, seminal vescicles, prostate and penis from 8-, 20-, 38-, and 70-day-old rats were sectioned and were immunostained with antisera to the neuropeptides calcitonin gene-related peptide (CGRP), vasoactive intestinal peptide (VIP) and neuropeptide Y (NPY), and to a general neuronal marker, protein gene product 9.5 (PGP 9.5). The testicular parenchyma and caput epididymis did not show any immunoreactivity. Very scattered CGRP-containing nerves were present in 8-day-old rats; numerous VIP-, CGRP-, and NPY-peptide-containing nerves were observed in the cauda epididymis, ductus deferens, accessory glands and penis of 20-day-old rats. The number of nerves increased in 35-day-old rats while no changes were observed in more adult rats. A parallel increase was seen for the immunostain for PGP 9.5. These data suggest that peptide-containing nerves appear in the genital system after birth and reach a full development before the completion of puberty. Peptide-containing nerves were visible first in the interstitial area and then spread in the muscular coat of the ducts, glands and of the blood vessels. While CGRP- and NPY-containing nerves were distributed in the vicinity of the muscle cells, VIP-containing nerves were also observed in the subepithelial regions, suggesting a possible role of this neuropeptide in the control of epithelial functions.
