We revealed earlier that induction of ovarian cysts in gilts by dexamethasone phosphate disodium salt (DXM) administration from the follicular phase of the estrous cycle (EC) changed the cholinergic innervation of the gonad. In the present study, the innervation of porcine ovaries by vesicular acetylcholine transporter (VAChT)-, neuronal nitric oxide synthase (nNOS)-, vasoactive intestinal peptide (VIP)- and somatostatin (SOM)-immunoreactive (IR) fibres, after induction of cystic changes from the middle luteal phase of the EC, was determined. The cystic changes were induced by DXM injections from days 7 to 21 of the EC, and 11 days later, the ovaries were collected. In the cystic ovaries, VAChT-, nNOS- and SOM-IR fibres were found around cysts and small tertiary follicles; nNOS-IR and also VAChT-IR fibres were observed near secondary follicles and veins; and VAChT- and nNOS-IR fibres were not found around cortical arteries. The number of VIP-IR fibres increased near the cysts and within the ground plexus, while the number of VAChT-IR fibres decreased within the medullar part of this structure. Thus, our study showed changes in the cholinergic innervation pattern of the porcine cystic ovaries induced from the middle phase of the cycle and confirmed that cystic ovary innervation depends partly on the phase of the EC in which the induction of cysts was started.
