Abstract
BACKGROUND Bisphenol-A (BPA) has a well-proven deleterious effect on the hypothalamicpituitary- gonadal axis. OBJECTIVES The current study investigated the therapeutic potentials of mesenchymal stem cells (MSCs) in a murine model of BPA-induced ovarian damage. METHODS Fifty adult female rats were divided into: Group 1; control group, Group IIa, IIb: rats were given oral gavage of BPA (25 and 50 mg/Kg body weight respectively) on a daily basis for 15 days, and Group IIIa, IIIb; rats were intravenously treated with of MSCs (106 cells) after receiving the last dose of BPA as in group II. Plasma and ovarian tissue levels of Malondialdehyde (MDA) and gonadal axis hormones were assessed. Apoptosis was evaluated by TUNNEL assay and by apoptosis markers (FAS, FASL, Caspase 3, SLTM). A histological examination of ovarian tissue was also conducted. RESULTS BPA resulted in a significant elevation in plasma levels of LH, FSH, and ovarian tissue levels of MDA and a significant decrease in estradiol and progesterone. All genetic and protein markers of apoptosis were elevated in BPA treated group with decreased oestrogen receptor expression in the ovarian tissue. Increased apoptotic cells were confirmed by TUNEL assay. A high dose of BPA was able to increase the number of atretic follicles in the ovarian tissue whereas the numbers of primordial, primary, secondary and Graafian follicles were decreased. All the laboratory and histological abnormalities were ameliorated by treatment with MSCs. CONCLUSION The antioxidant and anti-apoptotic effects of MSCs could possibly explain the ability of this therapeutic modality to ameliorate BPA-induced-ovarian damage.

Abstract
The detailed reproductive physiology of cockatoos based on gonadal hormone dynamics is unclear. In this study, we aimed to investigate ovarian activity by monitoring urofecal sex steroid hormone profiles in a captive female white cockatoo (Cacatua alba) and to noninvasively reveal basic reproductive physiology by comparing the hormone profiles with the laying dates, body mass changes, and molt progress. Urofeces were collected regularly for approximately 4 years from one female that frequently laid unfertilized eggs under single-rearing conditions. Urofecal progesterone (P4) and estradiol-17β (E2) were measured by enzyme immunoassay. In addition, body mass and the number of fallen feathers were measured periodically. The urofecal P4 concentration peaked at an average of 17.7 days after the start of the rise in urofecal E2 concentration, and egg laying began on the day after the peak urofecal P4 concentration. The clutch size was usually two eggs, with an average interval of 4.5 days between eggs in each egg-laying cycle. There was a significant correlation between the dynamics of E2 concentration in urofeces and body mass. The results strongly suggest that E2 and P4 reflect the follicle growth and ovulation status, respectively, and that noninvasive monitoring of hormone dynamics using urofeces can accurately capture ovarian activity in the white cockatoo. Furthermore, changes in body mass can predict follicular growth, and reproduction and molt are antagonistic.

Abstract
OBJECTIVES Gonadal hormone is essential for the health of postmenopausal women, however, few studies have focused on the epidemiological distribution of gonadal hormones in postmenopausal women in very late postmenopausal women. This study aims to investigate and analyze the differences of serum gonadal hormone content and its influential factors among female centenarians in Hainan, China. METHODS The questionnaire and physical examination data of 741 female centenarians and 401 elderly females in Hainan Province were collected, and venous blood samples were taken to detect the indexes of lipid metabolism, bone metabolism, and gonadal hormone. The differences of gonadal hormones and relavant factors in female centenarians were analyzed and compared. RESULTS The serum levels of estradiol and progesterone of female centenarians were significantly higher than those of the elderly females (both P<0.001). The serum levels of estradiol and testosterone of ethnic minority centenarians were higher than those in Han nationality (P<0.001), and the serum estradiol and testosterone concentrations were relatively higher when the daily activities were more than 10 min (both P<0.05). Serum estradiol concentration was negatively correlated with apolipoprotein A-I, high density lipoprotein, triglyceride and bone formation markers such as calcium, inorganic phosphorus and vitamin D3, and was positively correlated with the special sequence of β-collagen (markers of bone resorption) (all P<0.01). CONCLUSIONS For the extremely late postmenopausal women (such as centenarians), there may be characteristic expressions of gonadal hormones, especially estradiol. There is an unprotective correlation of serum estradiol with lipid metabolism index and bone metabolism index in female centenarians, so it is necessary to evaluate the estrogen content and the use of estrogen therapy in postmenopausal women.

Abstract
Puberty is a dynamic period marked by changing levels of sex hormones, the development of secondary sexual characteristics and reproductive maturity. This period has profound effects on various organ systems, including the immune system. The critical changes that occur in the immune system during pubertal onset have been shown to have implications for autoimmune conditions, including Multiple Sclerosis (MS). MS is rare prior to puberty but can manifest in children after puberty. This disease also has a clear female preponderance that only arises following pubertal onset, highlighting a potential role for sex hormones in autoimmunity. Early onset of puberty has also been shown to be a risk factor for MS. The purpose of this review is to overview the evidence that puberty regulates MS susceptibility and disease activity. Given that there is a paucity of studies that directly evaluate the effects of puberty on the immune system, we also discuss how the immune system is different in children and mice of pre- vs. post-pubertal ages and describe how gonadal hormones may regulate these immune mechanisms. We present evidence that puberty enhances the expression of co-stimulatory molecules and cytokine production by type 2 dendritic cells (DC2s) and plasmacytoid dendritic cells (pDCs), increases T helper 1 (Th1), Th17, and T follicular helper immunity, and promotes immunoglobulin (Ig)G antibody production. Overall, this review highlights how the immune system undergoes a functional maturation during puberty, which has the potential to explain the higher prevalence of MS and other autoimmune diseases seen in adolescence.

Abstract
There are various sex differences in sleep/wake behaviors in mice. However, it is unclear whether there are sex differences in sleep homeostasis and arousal responses and whether gonadal hormones are involved in these sex differences. Here, we examined sleep/wake behaviors under baseline condition, after sleep deprivation by gentle handling, and arousal responses to repeated cage changes in male and female C57BL/6 mice that are hormonally intact, gonadectomized, or gonadectomized with hormone supplementation. Compared to males, females had longer wake time, shorter non-rapid eye movement sleep (NREMS) time, and longer rapid eye movement sleep (REMS) episodes. After sleep deprivation, males showed an increase in NREMS delta power, NREMS time, and REMS time, but females showed a smaller increase. Females and males showed similar arousal responses. Gonadectomy had only a modest effect on homeostatic sleep regulation in males but enhanced it in females. Gonadectomy weakened arousal response in males and females. With hormone replacement, baseline sleep in gonadectomized females was similar to that of intact females, and baseline sleep in gonadectomized males was close to that of intact males. Gonadal hormone supplementation restored arousal response in males but not in females. These results indicate that male and female mice differ in their baseline sleep-wake behavior, homeostatic sleep regulation, and arousal responses to external stimuli, which are differentially affected by reproductive hormones.

Abstract
Many diseases of the respiratory system occur differently in males and females, indicating a possible role of gonadal hormones in respiratory control. We hypothesized that testosterone (T) is important for the ventilatory chemosensitivity responses in males. To test this hypothesis, we evaluated ventilation (V̇ E), metabolic rate and body temperature (Tb) under normoxia/normocapnia, hypercapnia and hypoxia in orchiectomized (ORX), ORX with testosterone replacement (ORX + T) or flutamide (FL, androgen receptor blocker)-treated rats. We also performed immunohistochemistry to evaluate the presence of androgen receptor (AR) in the carotid body (CB) of intact males. Orchiectomy promoted a reduction V̇ E and ventilatory equivalent (V̇ E /V̇ O2) under room-air conditions, which was restored with testosterone treatment. Moreover, during hypoxia or hypercapnia, animals that received testosterone replacement had a higher V̇ E and V̇ E /V̇ O2 than control and ORX, without changes in metabolic and thermal variables. Flutamide decreased the hypoxic ventilatory response without changing the CO2-drive to breathe, suggesting that the testosterone effect on hypercapnic hyperventilation does not appear to involve the AR. We also determined the presence of AR in the CB of intact animals. Our findings demonstrate that testosterone seems to be important for maintaining resting V̇ E in males. In addition, the influence of testosterone on V̇ E, either during resting conditions or under hypoxia and hypercapnia, seems to be a direct and specific effect, as no changes in metabolic rate or Tb were observed during any treatment. Finally, a putative site of testosterone action during hypoxia is the CB, since we detected the presence of AR in this structure.

Abstract
Pregnancy epulis is a tumor-like lesion that results from aggravating gingivitis due to high level of gonadal hormone concentration. Pregnancy epulis is commonly manifested as a single lump. A case of multiple pregnancy epulises, which has been rarely explored, is reported in this paper. The patient received no other treatment but a single supragingival scaling. Results showed no remarkable changes in the lesion. However, all the epulides regressed spontaneously in five months after the parturition.

Abstract
Previous work from our lab revealed that adult female rats have increased levels of myelin basic protein (MBP), a marker for myelination, in the orbitofrontal cortex (OFC) as compared to adult males. The goal of the present study was to determine the role of gonadal hormones, acting either in adulthood or at puberty, in the development of an adult sex difference in OFC levels of MBP. In an initial experiment, we replicated our previous results demonstrating that gonadally intact female rats have increased levels of MBP in the OFC as compared to males. In a second experiment, gonadectomy in adulthood did not alter MBP levels in rats of either sex. In a third experiment, gonadectomy immediately prior to pubertal onset resulted in significant reduction of levels of MBP in adult females but not males. This reduction eliminated the sex difference in adult MBP levels in the OFC. These results reveal puberty to be an organizational time point for a sex difference in the OFC of adult rats in levels of a marker of myelination. This neuroanatomical difference may contribute to observed sex differences in OFC-associated behaviors including in inhibitory control.

Abstract
OBJECTIVE The aim of this study was to investigate possible relationships among hematologic factors, psychological dimensions, the presence of self-reported sleep problems, and clinical characteristics in patients with burning mouth syndrome (BMS). METHODS Twenty-five postmenopausal female patients with primary BMS (aged 55.2 ± 9.6 years) were included. All participants underwent clinical and psychological evaluations and blood sampling. The patients were subdivided according to the absence or presence of the self-reported sleep problems. RESULTS Pain intensity of BMS patients with sleep problems was significantly higher than those without sleep problems, and the severity of oral complaints was correlated with the presence of depression, anxiety, hostility, phobia, and psychosis. Estradiol levels were significantly lower, and FSH and LH levels were higher in BMS patients with sleep problems than those without sleep problems. DISCUSSION BMS patients with sleep problems may suffer inharmonious psychoneuroendocrinological interactions that might worsen oral BMS symptoms.

Abstract
OBJECTIVE Functional gastrointestinal disorders affect females more often. Changes in colonic motility may be etiological co-factors for the clinical symptoms. The aim of the present study was to analyze the influence of gonadal hormones on colonic contractile activity. METHODS In vitro measurements of colonic contractile activity in longitudinal smooth muscle strips of female and male Lewis rats were performed in an organ chamber experiment. After the administration of a gonadal hormone estradiol [EST], progesterone [PROG] and testosterone [TEST]) or ethanol solution as control, stimulation with acetylcholine (ACh) or inhibition with norepinephrine (NE) was performed. RESULTS Compared to the smooth muscle strips of male rats, significantly higher spontaneous colonic contractile activity (SCCA) was observed in female animals. Increasing doses of ACh showed the progressive stimulation of SCCA whereas rising doses of NE resulted in a stepwise inhibition of SCCA, respectively. EST superfusion displayed an inhibitory effect on SCCA in both sexes and inhibited the ACh effect in female rats. Similarly, acute superfusion with high-dose PROG inhibited SCCA in females. Acute TEST superfusion inhibited SCCA in males and led to significant higher colonic contractile activity in males following subsequent stimulation with ACh. In female rats, the inhibitory effect of NE was reduced by prior exposure to TEST. CONCLUSION In our in vitro study the acute exposure of colonic smooth muscle tissue to gonadal hormones led to sex-dependent changes in SCCA and translated in a modified response of smooth muscle strips to both pro-contractile and anti-contractile neurotransmitters.

Abstract
Endomorphin-1 (EM-1) was reported to have very high affinity and selectivity for μ-opioid receptor (MOR). However, it remained unclear whether EM-1 and MOR were involved in the pathologies of endometriosis resulting in reduced fertility. In this study, RT-PCR, radioimmunoassay, immunohistochemistry, and Western blot were used, respectively. The results showed that the immune positive cells of EM-1 in hypothalamus, pituitary, and ovaries were significantly increased in endometriosis model rats, accompanied by the increase of plasma level of EM-1 and the decrease of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and progesterone (P). Interestingly, EM-1 was negatively correlated with FSH and LH (p < 0.05). More importantly, Naloxone (MOR antagonist) can significantly reduce the levels of EM-1 in serum, hypothalamus, pituitary, and ovaries, while increased the levels of FSH and LH. In conclusion, our results suggested that EM-1 may be involved in the pathogenesis of the endometriosis-associated infertility by regulating hypothalamus-pituitary-ovarian axis, and Naloxone may be a new alternative drug for the treatment of endometriosis.

Abstract
The aim of this study was to investigate the effect of testosterone and oestrogen on regulating organic cation transporters (Octs) and multidrug and toxin extrusions (Mates) expression in the kidney of mice and urinary excretion of metformin. 8 week‐old male db/db mice were treated with estradiol (5 mg/kg), testosterone (50 mg/kg) or olive oil with same volume. Metformin (150 mg/kg) was injected in daily for successive 7 days. Plasma, urine and tissue concentrations of metformin were determined by liquid chromatography‐tandem mass spectrometry (LCMS) assay. Western blotting and Real‐time PCR analysis were successively used to evaluate the renal protein and mRNA expression of Octs and MATEs. After treatment, the protein expression of Mate1 and Oct2 in testosterone group was significantly increased than those in control group (both P < 0.05). The protein expression of Mate1 and Oct2 in estradiol group was significantly reduced by 29.4% and 43.3%, respectively, compared to those in control group (all P < 0.05). These data showed a good agreement with the change in mRNA level (all P < 0.05). The plasma metformin concentration (ng/ml) in mice treated with estradiol was significantly higher than control and testosterone group (677.56 ± 72.49 versus 293.92 ± 83.27 and 261.46 ± 79.45; P < 0.01). Moreover, testosterone increased the metformin urine excretion of mice while estradiol decreasing (both P < 0.01). Spearman correlation analysis showed that gonadal hormone was closely associated with Mate1 and Oct2 expression and metformin urine excretion in db/db mice (all P < 0.05). Testosterone and oestrogen exerted reverse effect on metformin urinary excretion via regulating Octs and Mates expression in the kidney of mice.

Abstract
Ischemic edema can alter the structure and permeability of the blood-brain barrier. Recent studies have reported that progesterone reduces cerebral edema after cerebral ischemia. However, the underlying mechanism of this effect has not yet been elucidated. In the present study, progesterone effectively reduced Evans blue extravasation in the ischemic penumbra, but not in the ischemic core, 48 hours after cerebral ischemia in rats. Progesterone also inhibited the down-regulation of gene and protein levels of occludin and zonula occludens-1 in the penumbra. These results indicate that progesterone may effectively inhibit the down-regulation of tight junctions, thereby maintaining the integrity of the blood-brain barrier and reducing cerebral edema.

Abstract
Several forms of depression are unique to women because of their apparent association with changes in gonadal hormones, which in turn modulate neuroregulatory systems associated with mood and behavior. This review examines the evaluation and treatment of depression that occurs premenstrually, postpartum, or in the perimenopause on the basis of current literature. The serotonergic antidepressants consistently show efficacy for severe premenstrual syndromes (PMSs) and premenstrual dysphoric disorder (PMDD), and are the first-line treatment for these disorders. The use of antidepressants for postpartum depression is compromised by concerns for effects in the infants of breast-feeding mothers, but increasing evidence suggests the relative safety of the antidepressant medications, and the risk calculation should be made on an individual basis. Estradiol may be effective for postpartum depression and for moderate-to-severe major depression in the perimenopause. In spite of its frequent use, progesterone is not effective for the mood and behavioral symptoms of PMS/PMDD, postpartum depression, or perimenopausal depressive symptoms.
