Pinto J, Cera N, Pignatelli D. Psychological symptoms and brain activity alterations in women with PCOS and their relation to the reduced quality of life: a narrative review. J Endocrinol Invest 2024; 47:1-22. [PMID: 38485896 PMCID: PMC11196322 DOI: 10.1007/s40618-024-02329-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 02/03/2024] [Indexed: 06/25/2024]
Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is the most common feminine endocrine disorder, characterized by androgen excess, ovulatory dysfunction, and polycystic ovarian morphology. The negative impact of symptoms on the quality of life (QoL) of patients is still not clear. PURPOSE The present review aimed at studying the impact of the symptoms, the psychological symptoms, and brain alterations in women with PCOS. METHODS A systematic search was undertaken for studies that assessed the impact of PCOS symptoms on QoL, psychological symptoms, and brain alterations in PCOS patients. RESULTS Most of the information about QoL came from psychometric studies, which used culture-based questionnaires. Alterations of sleep quality, body image, and mood disorders can negatively affect the QoL of the patients. Sexual satisfaction and desire were affected by PCOS. Brain imaging studies showed functional alterations that are associated with impairments of visuospatial working memory, episodic and verbal memory, attention, and executive function. CONCLUSIONS Several factors can negatively influence the quality of life of the patients, and they are directly related to hyperandrogenism and the risk of infertility. In particular, obesity, hirsutism, acne, and the fear of infertility can have a direct impact on self-esteem and sexual function. Metabolic and psychiatric comorbidities, such as mood, anxiety, and eating disorders, can affect the well-being of the patients. Moreover, specific cognitive alterations, such as impairments in attention and memory, can limit PCOS patients in a series of aspects of daily life.

Stress responses to bacterial and viral mimetics in polycystic ovary syndrome model rats. Brain Behav Immun Health 2024; 38:100772.

Abstract
Polycystic ovary syndrome (PCOS) is associated with an increased risk of psychological distress as well as enhanced responses to psychosocial stress. Recently, it was hypothesized that PCOS patients may be at high risk of novel COVID-19 infections and worse clinical presentations during such infections. Here, we evaluated the effects of PCOS on stress responses to bacterial and viral mimetics using dihydrotestosterone-induced PCOS model rats. Lipopolysaccharide (LPS; a bacterial mimetic) or polyinosinic-polycytidylic acid (Poly-IC; a viral mimetic) was injected into PCOS model rats (PCOS) and non-PCOS rats (control), and the rats' stress responses were evaluated. In the PCOS group, the rats' anorectic and febrile responses to LPS injection were enhanced, whereas their anorectic and febrile responses to Poly-IC injection were unaltered. The PCOS group also exhibited greater changes in peripheral cytokine levels in response to LPS, but not Poly-IC. On the contrary, after the injection of Poly-IC depressed locomotor activity was more evident in the PCOS group, whereas no such changes were observed after LPS injection. These findings indicate that although the stress responses of PCOS model rats to infection may be enhanced, the patterns of change in stress responses and their underlying mechanisms may differ between bacterial and viral infections.

Cera N, Pinto J, Pignatelli D. The Role of Oxytocin in Polycystic Ovary Syndrome: A Systematic Review. Curr Issues Mol Biol 2024; 46:5223-5241. [PMID: 38920985 PMCID: PMC11201948 DOI: 10.3390/cimb46060313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Revised: 05/21/2024] [Accepted: 05/23/2024] [Indexed: 06/27/2024] Open
Abstract
Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder that affects women of reproductive age, representing the primary cause of anovulatory infertility. The nonapeptide oxytocin (OT) plays an important role in cognitive, emotional, and reproductive functions in human beings. Oxytocin receptors are expressed in several body parts, including the ovaries. Despite this, the possible role played by oxytocin in symptoms of PCOS is not clear. The present systematic review aimed at understanding the presence of possible oxytocin level alterations in PCOS, the connection between alterations of OT levels and the symptoms of PCOS, and the effect of oxytocin administration in PCOS. After a systematic search in the principal databases, eight studies, five human and three animal, were included. Four human studies and one animal study highlighted the role played by oxytocin in fertility issues related to PCOS. Three human and two animal studies investigated the role of body weight and OT levels. Studies that analyzed oxytocin basal levels in women agreed that PCOS is associated with a reduction in the serum level of oxytocin. Two human studies and one animal study agreed about lower levels of oxytocin, confirming a possible implication of the dysfunction of OT in the pathogenesis of PCOS.

Progesterone treatment reduces food intake and body weight in ovariectomized female rats. Steroids 2024; 203:109367.

Abstract
While the effects of progesterone on body weight and appetite in pre-menopausal conditions have been well elucidated, its effects in post-menopausal conditions have not been clarified. On the contrary, the effects of estrogen on body weight and appetite in post-menopausal conditions have been well established. In this study, the effects of progesterone treatment on body weight, appetite, and fat mass in ovariectomized rats were evaluated. In addition, the central and/or peripheral levels of oxytocin (OT), leptin, and their receptors, which are potent anorectic factors, were examined. Female rats were ovariectomized and divided into control, progesterone-treated, and estrogen-treated groups. Body weight, food intake, and subcutaneous fat mass were lower in both the progesterone and estrogen groups than in the control group. The estrogen group exhibited higher serum OT levels than the control group, whereas the OT levels of the progesterone and control groups did not differ. The serum leptin levels of both the progesterone and estrogen groups were lower than those of the control group. Gene expression analysis of OT, leptin, and their receptors in the hypothalamus and adipose tissue found few significant differences among the groups. Hypothalamic neuropeptide Y (NPY) and pro-opiomelanocortin (POMC) mRNA levels involved in appetite regulation were slightly altered in the progesterone and estrogen groups. These findings suggest that progesterone treatment may have favorable effects on body weight, appetite, and fat mass regulation in post-menopausal conditions and that the mechanisms underlying these effects of progesterone differ from those underlying the effects of estrogen.

Age-Dependent Changes in the Effects of Androgens on Female Metabolic and Body Weight Regulation Systems in Humans and Laboratory Animals. Int J Mol Sci 2023; 24:16567.

Abstract
In recent years, the effects of androgens on metabolic and body weight regulation systems and their underlying mechanisms have been gradually revealed in females. In women and experimental animals of reproductive age, androgen excess can adversely affect metabolic functioning, appetite, and body weight regulation. In addition, excess androgens can increase the risk of metabolic disorders, such as obesity, insulin resistance, and diabetes. These unfavorable effects of androgens are induced by alterations in the actions of hypothalamic appetite-regulatory factors, reductions in energy expenditure, insulin resistance in skeletal muscle, and β-cell dysfunction. Interestingly, these unfavorable effects of androgens on metabolic and body-weight regulation systems are neither observed nor evident in ovariectomized animals and post-menopausal women, indicating that the adverse effects of androgens might be dependent on the estrogen milieu. Recent findings may provide novel sex- and age-specific strategies for treating metabolic diseases.

Developmental Changes in Hypothalamic and Serum Oxytocin Levels in Prenatally Normally Nourished and Undernourished Rats. Nutrients 2023; 15:2768. [PMID: 37375670 DOI: 10.3390/nu15122768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Revised: 06/12/2023] [Accepted: 06/14/2023] [Indexed: 06/29/2023] Open
Abstract
Changes in the activities of some metabolic factors have been suggested to increase the risk of conditions associated with the Developmental Origins of Health and Disease (DOHaD). We examined changes in oxytocin (OT), a metabolic factor, and OT receptor (OTR) mRNA levels throughout the developmental period in rats of intrauterine undernutrition. Pregnant rats were divided into two groups: a maternal normal nutrition (mNN) and maternal undernutrition (mUN) group. Serum OT concentrations and hypothalamic mRNA levels of OT and OTR were measured in both offspring at various postnatal stages. Both offspring showed significant increases in serum OT concentrations during the neonatal period, significant reductions around the pubertal period, and significant increases in adulthood. Hypothalamic OT mRNA expression levels gradually increased from the neonatal to pubertal period and decreased in adulthood in both offspring. In the pre-weaning period, hypothalamic OT mRNA expression levels were significantly lower in the mUN offspring than in the mNN offspring. In the mUN offspring, hypothalamic OTR mRNA expression levels transiently increased during the neonatal period, decreased around the pubertal period, and increased again in adulthood, whereas transient changes were not detected in mNN offspring. These changes could affect nutritional and metabolic regulation systems in later life and play a role in the mechanisms underlying DOHaD.

New discoveries on the interaction between testosterone and oxytocin in male rats - Testosterone-mediated effects of oxytocin in the prevention of obesity. Physiol Behav 2023; 266:114199. [PMID: 37062515 DOI: 10.1016/j.physbeh.2023.114199] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 04/03/2023] [Accepted: 04/14/2023] [Indexed: 04/18/2023]
Abstract
Sex steroid hormones are important for the maintenance of metabolism in both sexes. Oxytocin (OT) is a neuropeptide that is synthesized in hypothalamic regions, secreted from the posterior lobe of the pituitary gland, and is involved in the control of appetite, body weight, and metabolism. Estrogen and OT both play a role in the metabolism of nutrients, and OT has potential in the prevention of obesity. However, the relationship between testosterone and OT remains unclear. Therefore, the present study investigated the relationship between testosterone and OT in hypogonadal male rats and male rats receiving testosterone replacement therapy. The results obtained showed that testosterone increased serum OT levels and promoted the secretion of adiponectin from visceral fat, and reduced body fat directly and/or indirectly through OT and adiponectin. Testosterone also increased the expression of OT receptors in the hypothalamus to increase sensitivity to OT, and perhaps because of this, OT administration had the effect of reducing food intake and body weight gain in both normal and castrated rats, and this effect was stronger in normal rats. In other words, the preventative effects of OT on obesity may be synergistic with testosterone. Collectively, the present results indicate that testosterone exerts indirect effects to prevent obesity and atherosclerosis through OT and adiponectin. In conclusion, testosterone replacement therapy is useful for preventing obesity caused by hypogonadism, and OT has potential in supportive medicine to prevent obesity and adult diseases.

Abstract
To elucidate the reproductive role of oxytocin (OXT) in ovarian steroidogenesis and its functional interaction with bone morphogenetic proteins (BMPs), the effects of OXT on ovarian steroidogenesis were investigated by utilizing primary culture of rat granulosa cells and human granulosa KGN cells. Here we revealed that the OXT receptor was expressed in both rat and human granulosa cells and that OXT treatment significantly increased follicle-stimulating hormone (FSH)- and forskolin (FSK)-induced progesterone production, but not estradiol production, by rat and human granulosa cells, respectively. In accordance with the effects of OXT on progesterone production, OXT enhanced mRNA expression of CYP11A1 and HSD3B2 induced by FSK in human granulosa cells. Of note, OXT enhanced the phosphorylation of SMAD1/5/9 and the transcription of ID1 induced by BMP-15, but not those induced by BMP-6, in human granulosa cells. It was also revealed that OXT treatment upregulated the expression of BMPR2, a crucial type-II receptor of BMP-15, and enhanced the BMP-15-induced expression of inhibitory SMAD6 by human granulosa cells. Collectively, it was shown that OXT accelerates ovarian progesterone synthesis with upregulation of BMP-15 activity, leading to a fine-tuning of ovarian steroidogenesis (186 words).

Changes in Serum Oxytocin Levels under Physiological and Supraphysiological Gonadal Steroid Hormone Conditions in Women of Reproductive Age: A Preliminary Study. Nutrients 2022; 14:nu14245350. [PMID: 36558508 PMCID: PMC9787714 DOI: 10.3390/nu14245350] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2022] [Revised: 12/14/2022] [Accepted: 12/15/2022] [Indexed: 12/23/2022] Open
Abstract
Oxytocin (OT) affects many behavioral, psychological, and physiological functions, including appetite and body weight regulation. Central and peripheral OT levels are markedly affected by gonadal steroids, especially estrogen, and the anorectic effects of estrogen are partially mediated by OT in rodents. In this study, the relationship between the estrogen milieu and serum OT levels was evaluated in women of reproductive age under physiological (n = 9) and supraphysiological estrogenic conditions (n = 7). Consequently, it was found that serum OT levels were increased in physiological (the ovulatory phase) and supraphysiological (on the day of the human chorionic gonadotropin trigger in an ovarian stimulation cycle) estrogenic conditions, and that serum OT levels were positively correlated with serum estradiol levels. On the other hand, serum OT levels were negatively correlated with serum progesterone levels, and there was no correlation between serum and follicular OT levels. These results suggest that OT levels may be positively and negatively regulated by estrogen and progesterone, respectively, in humans. However, the physiological roles of these actions of gonadal steroids on OT remain unclear.
