Polycystic ovary syndrome (PCOS) is a common disorder that affects various facets of fertility. Although the ovarian and metabolic aspects of the disease is well studied, its role in uterine dysfunction is not well understood. Our objective was to review the features of endometrial and uterine aberrations in women with PCOS. A systematic literature search was performed in PubMed, Medline, and the Cochrane Library databases for papers published in English up to March 2020. The following key words were used for the search: polycystic ovary syndrome, poly cystic ovarian disease, polycystic ovaries, PCOS, PCOD, PCO, PCOM, oligoovulation, anovulation, oligomenorrhea, amenorrhea, hyperandrogenism and this was combined with terms; endometrium, infertility, uterus, progesterone resistance, endometrial hyperplasia, pregnancy outcomes, preterm delivery. In this review, we highlight various uterine pathologies that are associated with PCOS and explore its impact on fertility. We also discuss key uterine molecular pathways that are altered in PCOS that may be related to infertility, endometrial hyperplasia and cancer.

Pomegranate (Punica granatum) is a widely cultivated fruit historically recognized for its health benefits and is regarded as a nutritional powerhouse. Pomegranate has a unique composition of bioactive compounds including hydrolysable tannins, anthocyanins, and other polyphenolic components. Of those, punicalagin and its subsequent metabolites are the most extensively studied, demonstrating antioxidant, anti-inflammatory, anti-cancer, and anti-nociceptive activity.

Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder, affecting approximately 11-13% of women of reproductive age. Women with PCOS experience a higher prevalence of infertility, pregnancy complications, and cardiometabolic disorders such as obesity, insulin resistance, and type 2 diabetes mellitus. Furthermore, psychiatric comorbidities, including depression and anxiety, significantly impact the quality of life in this population.

Metabolic syndrome (MetS) is an indicator and diverse endocrine syndrome that combines different metabolic defects with clinical, physiological, biochemical, and metabolic factors. Obesity, visceral adiposity and abdominal obesity, dyslipidemia, insulin resistance (IR), elevated blood pressure, endothelial dysfunction, and acute or chronic inflammation are the risk factors associated with MetS. Abdominal obesity, a hallmark of MetS, highlights dysfunctional fat tissue and increased risk for cardiovascular disease and diabetes.

Diethylstilbestrol (DES) is an estrogenic endocrine disrupting chemical (EDC) that was prescribed to millions of pregnant women worldwide, leading to increased rates of infertility in the exposed offspring. We have previously demonstrated that this reduced fertility persists for multiple generations in the mouse. However, how altered ovarian function contributes to this infertility is unknown.
