Ovarian DβH- and/or NPY-, SOM-, GAL-IR nerve fibres (↑) in the control and T-treated gilts. Within the cortical ground plexus of the control gilts numerous DβH- (a) and not numerous SOM-(c) IR nerve fibres are visible, while in the gilts receiving T anoticeable decrease in the population of DβH- (b) and SOM- (D) IR fibres is present. In the control ovary numerous DβH-IR fibres near medium tertiary follicle (e). Note a drop in the number of these nerve fibres in the T-injected gilt (f). Around medium tertiary follicles of the control (g) and T-treated (h) gilts the population of NPY-IR nerve fibres are similar. Within the medullar ground plexus of the control gilts numerous DβH- (i) or not numerous NPY- (k) IR nerve fibres are present. In turn, after Ttreatment, a decrease in the number of DβH- (j) and NPY- (l) immunoreactivity is visible. A greater population of DβH-IR fibres is present in the vicinity of the medullar artery in the control gilt (m) than after T treatment (n). The numbers of GAL-IR processes around medullar arteries of the control (o) and T-injected (p) gilts are similar. Negative controls for DβH (r), SOM (s), NPY (t) and GAL (u)
