Abstract
There is evidence of the existence of an intraovarian gonadotropin-releasing hormone (GnRH) system. There are also reports about the influence of extrinsic ovarian innervation in gonadal function. Therefore, it is interesting to study the relationship between ovarian sympathetic innervation and GnRH to shed light on possible physiological and pathophysiological implications. This work aimed to investigate whether noradrenergic stimulation of the superior mesenteric ganglion (SMG) can modify the levels of ovarian GnRH and cause functional and morphological changes in the gonad through the ovarian plexus nerve (OPN), during estrus and diestrus II in rats. The SMG-OPN-Ovary system and an ovary without extrinsic innervation were removed from Holtzman rats in estrus and diestrus II stages and placed in specially designed cuvettes containing Krebs-Ringer buffer. In the experimental groups, SMGs and denervated ovaries were stimulated with 10-6 M noradrenaline (NA). GnRH and progesterone levels (in the ovarian incubation medium) and the mRNA expression of 3beta-hydroxysteroid dehydrogenase (Hsd3b3), 20alpha-hydroxysteroid dehydrogenase (Akr1c18), Bax, and Bcl2 were analyzed. Histological studies of the ovaries were performed. In estrus, NA decreased GnRH levels in both experimental schemes. Furthermore, progesterone levels increased while the Akr1c18 expression and Bax/Bcl2 ratio decreased, without causing changes in ovarian morphology. In diestrus, the noradrenergic stimulation of the ganglion increased GnRH levels, decreased progesterone levels, and increased Akr1c18 expression and Bax/Bcl2 ratio. Follicles with histoarchitecture alterations and corpus luteum with signs of cell death were observed. In denervated ovaries, NA increased the levels of GnRH and progesterone. Furthermore, NA decreased the Bax/Bcl2 ratio and histological studies revealed signs compatible with a possible atretogenic effect. In conclusion, noradrenergic stimulation of the SMG-OPN pathway regulates ovarian cyclicity. The SMG modulates the cross-talk between NA and ovarian GnRH, protecting the ovary from atretogenic effects and luteal apoptosis during estrus while inducing luteal regression in the diestrus II.

Abstract
In rats with polycystic ovarian syndrome (PCOS) induced by estradiol valerate (EV) injection, sectioning of the vagus nerve in the juvenile stage restores ovulatory function, suggesting that the vagus nerve stimulates the onset and development of PCOS. We analyzed whether in adult rats, the role played by the vagus nerve in PCOS development is associated with the nerve’s regulation of noradrenergic activity in the celiac superior mesenteric ganglion (CSMG). Ten-day-old rats were injected with corn oil [vehicle (Vh)] or EV (2 mg). At 76 days of age, rats injected with Vh or EV were subjected to sham surgery or the sectioning of one or both vagus nerves (vagotomy). The animals were sacrificed at 80–82 days of age at vaginal estrus smear. Compared to Vh-treated animals, EV-induced PCOS rats showed a lack of ovulation, the presence of follicular cysts, and a high concentration of testosterone, without changes in noradrenaline concentrations in the CSMG or ovaries. In PCOS rats, sham surgery lowered serum testosterone and noradrenaline concentrations in the CSMG but did not restore ovulation. In animals with PCOS, vagotomy lowered testosterone concentrations to a larger degree than in sham-surgery animals. The ovaries of rats with PCOS and vagotomy showed fresh corpora lutea, indicating ovulation. In EV-treated rats with unilateral vagotomy, the concentration of noradrenaline in the CSMG was similar to that in rats with PCOS and sham surgery, which did not ovulate, while in the ovaries of PCOS rats with left or bilateral vagotomy, the noradrenaline concentration was lower than that in sham-surgery-treated animals. Our results suggest that the vagus nerve regulates PCOS development through a different mechanism than the increase in the noradrenergic activity in the CSMG; however, in ovaries, the restoration of ovulation is associated with a decrease in ovarian noradrenaline.

Abstract
Whether prolactin (PRL) has a luteotrophic or luteolytic effect in the rat ovary depends on the nature of the corpora lutea present in the ovaries and the hormonal environment to which they are exposed. The aim was to investigate the effect of PRL acting on the coeliac ganglion (CG) on the function of the corpora lutea on day 4 postpartum under either lactating or non-lactating conditions, using the CG-superior ovarian nerve-ovary system. The ovarian release of progesterone (P), estradiol, PGF2α, and nitrites was assessed in the ovarian compartment at different incubation times. Luteal mRNA expression of 3β-HSD, 20α-HSD, aromatase, PGF2α receptor, iNOS, Bcl-2, Bax, Fas and FasL was analysed in the corpus luteum of pregnancy at the end of the experiments. Comparative analysis of control groups showed that the ovarian release of P, nitrites, and PGF2α, the expression of PGF2α receptor, and the Bcl-2/Bax ratio were lower in non-lactating rats, with increased release of estradiol, and higher expression of aromatase, Fas and FasL, demonstrating the higher luteal functionality in ovaries of lactating animals. PRL added to the CG compartment increased the ovarian release of P, estradiol, nitrites and PGF2α, and decreased the Bcl-2/Bax ratio in non-lactating rats; yet, with the exception of a reduction in the release of nitrites, such parameters were not modified in lactating animals. Together, these data suggest that the CG is able to respond to the effect of PRL and, via a neural pathway, fine-tune the physiology of the ovary under different hormonal conditions.

Abstract
Oestradiol (E(2)) is a key hormone in the regulation of reproductive processes. The aims of this work were a) to examine the distributions of oestrogen receptor α (ERα) and ERβ in the neurons of the superior mesenteric ganglion (SMG) in the oestrus stage by immunohistochemistry, b) to demonstrate whether E(2) in the SMG modifies progesterone (P(4)), androstenedione (A(2)) and nitrite release in the ovarian compartment on oestrus day and c) to demonstrate whether E(2) in the ganglion modifies the activity and gene expression in the ovary of the steroidogenic enzymes 3β-hydroxysteroid dehydrogenase (3β-HSD) and 20α-hydroxysteroid dehydrogenase (20α-HSD). The ex vivo SMG-ovarian nervous plexus-ovary system was used. E(2), tamoxifen (Txf) and E(2) plus Txf were added in the ganglion to measure ovarian P(4) release, while E(2) alone was added to measure ovarian A(2) and nitrites release. Immunohistochemistry revealed cytoplasmic ERα immunoreactivity only in the neural somas in the SMG. E(2) increased ovarian P(4) and A(2) release at 15, 30 and 60 min but decreased nitrites. The activity and gene expression of 3β-HSD increased, while the activity and gene expression of 20α-HSD did not show changes with respect to the control. Txf in the ganglion diminished P(4) release only at 60 min. E(2) plus Txf in the ganglion reverted the effect of E(2) alone and the inhibitory effect of Txf. The results of this study demonstrate that ERα activation in the SMG has an impact on ovarian steroidogenesis in rats, thus providing evidence for the critical role of peripheral system neurons in the control of ovarian functions under normal and pathological conditions.

Androstenedione acts on the coeliac ganglion and modulates luteal function via the superior ovarian nerve in the postpartum rat. J Steroid Biochem Mol Biol 2011; 125:243-50.

Abstract
Androstenedione can affect luteal function via a neural pathway in the late pregnant rat. Here, we investigate whether androstenedione is capable of opposing to regression of pregnancy corpus luteum that occurs after parturition, indirectly, from the coeliac ganglion. Thus, androstenedione was added into the ganglionar compartment of an ex vivo coeliac ganglion-superior ovarian nerve-ovary system isolated from non-lactating rats on day 4 postpartum. At the end of incubation, we measured the abundance of progesterone, androstenedione and oestradiol released into the ovarian compartment. Luteal mRNA expression and activity of progesterone synthesis and degradation enzymes, 3β-hydroxysteroid-dehydrogenase (3β-HSD) and 20α-hydroxysteroid-dehydrogenase (20α-HSD), respectively, as well as the aromatase, Bcl-2, Bax, Fas and FasL transcript levels, were also determined. Additionally, we measured the ovarian release of norepinephrine, nitric oxide and luteal inducible nitric oxide synthase (iNOS) mRNA expression. The presence of androstenedione in the ganglion compartment significantly increased the release of ovarian progesterone, androstenedione and oestradiol without modifying 3β-HSD and 20α-HSD activities or mRNA expression. The ovarian release of oestradiol in response to the presence of androstenedione in the ganglion compartment declined with time of incubation in accord with a reduction in the aromatase mRNA expression. Androstenedione added to the ganglion compartment decreased FasL mRNA expression, without affecting luteal Bcl-2, Bax and Fas transcript levels; also increased the release of norepinephrine, decreased the release of nitric oxide and increased iNOS mRNA. In summary, on day 4 after parturition, androstenedione can mediate a luteotropic effect acting at the coeliac ganglion and transmitting to the ovary a signaling via a neural pathway in association with increased release of norepinephrine, decreased nitric oxide release, and decreased expression of FasL.

Abstract
The ovarian function is controlled by endocrine factors and neural influence. In late pregnant rat, androstenedione, from the coeliac ganglion, has a luteotrophic effect in the ex vivo coeliac ganglion-superior ovarian nerve-ovary system. In this work we investigate the presence of androgen receptors in the coeliac ganglion of late pregnant rats by immunohistochemistry. We also explore, from a physiological point of view, the potential participation of these receptors in the androstenedione ganglionic action on progesterone release and metabolism, as well as on nitrites release in the ovary compartment. The coeliac ganglion was isolated after being fixed in situ and immunohistochemistry was performed. In the system, three experimental groups were used with the addition of (a) androstenedione, (b) flutamide, and (c) androstenedione plus flutamide in the ganglion compartment. Progesterone and nitrite concentrations were determined in the ovary compartment at different incubation times. Corpora lutea samples isolated at the end of incubation were used to determine the expressions and activities of the progesterone synthesis (3beta-hydroxysteroid-dehydrogenase, 3beta-HSD) and degradation (20alpha-hydroxysteroid-dehydrogenase, 20alpha-HSD) enzymes. Immunohistochemistry revealed cytoplasmatic androgen receptor immunoreactivity in neural somas in the coeliac ganglion. In the coeliac ganglion-superior ovarian nerve-ovary system, androstenedione addition increased 3beta-HSD and decreased 20alpha-HSD, showed a tendency to decrease 20alpha-HSD expression, and increased nitrites release in relation to control. Androstenedione plus flutamide decreased progesterone and nitrites release in relation to the androstenedione group. This work demonstrates the presence of androgen receptors in neurons of celiac ganglion and provides evidence for the luteotrophic action of androstenedione via a neural pathway that may be mediated by these receptors.
