Abstract More than 1 out of 10 women worldwide are diagnosed with polycystic ovary syndrome (PCOS), the leading cause of female reproductive and metabolic dysfunction. Despite its high prevalence, PCOS and its accompanying morbidities are likely underdiagnosed, averaging > 2 years and 3 physicians before women are diagnosed. Although it has been intensively researched, the underlying cause(s) of PCOS have yet to be defined. In order to understand PCOS pathophysiology, its developmental origins, and how to predict and prevent PCOS onset, there is an urgent need for safe and effective markers and treatments. In this review, we detail which animal models are more suitable for contributing to our understanding of the etiology and pathophysiology of PCOS. We summarize and highlight advantages and limitations of hormonal or genetic manipulation of animal models, as well as of naturally occurring PCOS-like females.

Polycystic ovary syndrome (PCOS) is a common condition in women at reproductive age associated with reproductive and metabolic dysfunction. Proposed diagnosed criteria for PCOS include two out of three features: androgen excess, menstrual irregularity, and polycystic ovary appearance on ultrasound (PCO), after other causes of hyperandrogenism and dysovulation are excluded. Based on these diagnostic criteria, the most common phenotypes are the “classic PCOS” – hyperandrogenism and oligomenorrhea, with or without PCO; the “ovulatory phenotype” – hyperandrogenism and PCO in ovulatory women; and the “non-hyperandrogenic phenotype”, in which there is oligomenorrhea and PCO, without overt hyperandrogenism. The presence of obesity may exacerbate the metabolic and reproductive disorders associated with the syndrome. In addition, PCOS women present higher risk for type 2 diabetes and higher prevalence of cardiovascular risk factors that seems to be associated with the classic phenotype. The main interventions to minimize cardiovascular and metabolic risks in PCOS are lifestyle changes, pharmacological therapy, and bariatric surgery. Treatment with metformin has been shown to improve insulin sensitivity, lowering blood glucose and androgen levels. These effects are more potent when combined with lifestyle interventions. In conclusion, besides reproductive abnormalities, PCOS has been associated to metabolic comorbidities, most of them linked to obesity. Confounders, such as the lack of standard diagnostic criteria, heterogeneity of the clinical presentation, and presence of obesity, make management of PCOS difficult. Therefore, the approach to metabolic abnormalities should be tailored to the risks and treatment goals of each individual woman.

Low glucagon like peptide1 (GLP-1) level may contribute to the metabolic dysfunction in polycystic ovary syndrome (PCOS).  In this study, prospective therapeutic effects of incretin-based drugs; linagliptin versus liraglutide were investigated on letrozole induced PCOS rats. Animals were divided into five groups (control, PCOS, linagliptin, liraglutide and combined). Letrozole was administered for seven weeks (1mg/kg/day,orally). Linagliptin (3mg/kg/day,orally), liraglutide (1.2mg/kg/day,sc) and combined drugs were given for 4 weeks. Measurements of anthropometric, hemodynamics, blood glucose indices, HOMA-IR, serum lipids, TNF-α, NF-kB, and sex hormones were estimated. Antioxidant activities alongside immunohistochemical (PCNA) studies were assessed. The present results proved that both drugs significantly ameliorated most of anthropometric, glycemic, lipid, hormonal, inflammatory and antioxidant indices. Obvious histological improvement was obtained by linagliptin and combined therapy while being questionable by liraglutide . In conclusion, linagliptin caused evident ovarian histological advance rather than liraglutide. Linagliptin may represent a promise in alleviating metabolic, hormonal and unique beneficial histologic effects of PCOS.
