This article contains findings obtained from research on animals:
- The results from animal research studies should not be directly applied to humans and the results may not generalise to the human population.
- There may be significant differences between species in terms of physiology, physiology, and pharmacology, as well as differences in the way diseases and treatments are modelled in animals.
- Any conclusions drawn from animal research should be considered with caution and in the context of other types of research studies such as observational studies, clinical trials, and reviews of the literature.

Pomegranate juice extract may reduce the damage to the endometrium in Polycystic ovary syndrome through its antioxidant, anti-inflammatory, anti-fibrotic, and anti-proliferative effects.
To test the possible benefits of pomegranate juice extract (PJE) on endometrial injury in Polycystic ovary syndrome (PCOS), forty adult albino rats were divided into four groups, control, PJE-treated, letrozole-treated (PCOS), and PJE & PCOS groups. The respective treatments were administered for a duration of three weeks. Serum and tissue samples were assayed for Follicle-stimulating hormone, Luteinizing hormone, testosterone, estradiol, and malondialdehyde. Uterine samples were also tested using a range of histological staining techniques and a scanning electron microscope.
In the rat model of PCOS, significant increases in certain biochemical indicators in serum samples were observed while uterine sections showed numerous alterations to the endometrium, signs of inflammation and an increase in the endometrial collagen fiber content. Additionally, there was increased expression of certain immunohistochemical staining markers and a decrease in the mean number of pinopodes observed through scanning electron microscopy. However, these various potentially harmful biochemical, histological and immunohistochemical alterations were efficiently reduced with the administration of PJE. This points towards the potential benefits of PJE in addressing and potentially reducing endometrial injury associated with PCOS.

Randomised Controlled Trial PCOS Pomegranate Testosterone
In the methodology, the study employed a randomized controlled trial which involved 44 participants. The women, aged between 18 and 40 years, had all been diagnosed with polycystic ovary syndrome and had a body mass index exceeding 25 kg/m. They were randomly divided, with one group consuming 45 ml/day of concentrated pomegranate juice and the other group receiving no intervention. A variety of biomarkers for sex hormones, inflammation, and oxidative stress were measured before starting the trial and again after eight weeks.
Further discussion of the results revealed a significant decrease in testosterone levels among the overweight and obese women with polycystic ovary syndrome who took concentrated pomegranate juice over the eight week period, in contrast to those in the control group. Apart from testosterone, no significant changes were observed for luteinizing hormone, sex hormone-binding globulin levels or for markers of inflammation and oxidative stress between the two groups.
Pomegranate seed oil, rich in conjugated linolenic acid, potentially acts as a cytotoxic agent on tissue tumor cells, reducing polycystic ovary syndrome manifestations.

Experimental Study PCOS Pomegranate
First, data for this study was collected from several databases including the Cochran library, Medline, PubMed, SID, and Science Direct. Keyword searches incorporating phrases such as "medicinal plants", "polycystic ovary syndrome", "plant", "pomegranate extract", and "menstrual irregularities" were used to uncover relevant articles spanning from 1985 to 2021. The focus of the research was to investigate the impact of pomegranate seed oil, particularly its conjugated linolenic acid (CLN) content, on polycystic ovary syndrome, a prevalent endocrine disorder among women.
The results revealed that CLN, found abundantly in pomegranate seed oil, had been previously reported to exert a potent cytotoxic effect on tumor tissue cells within the body. This characteristic placed CLN as a potential agent in predenting cancer, lowering LDL cholesterol in the blood, reducing triacylglycerol accumulation in the liver, and importantly, mitigating the effects of polycystic ovary syndrome. Alongside this, the research also underscored the beneficial effects of conjugated linoleic acid (CLA), another group of linoleic acid isomers, in cancer growth inhibition, risk reduction of atherosclerosis, and body fat decrease.
Concentrated pomegranate juice consumption can potentially lower cardiovascular disease risk factors in women with polycystic ovary syndrome.

Randomised Controlled Trial Cardiovascular Disease PCOS Pomegranate
The study used a randomized clinical approach, enrolling 44 women identified with polycystic ovary syndrome, aged 18 to 40 years and above a certain body weight index. These participants were randomly divided into two groups: one group was given concentrated pomegranate juice (CPJ), while the other served as a control. Both groups were monitored over a period of 8 weeks, with baseline measurements taken for anthropometric measures, blood pressure, and biochemical parameters set at the onset and then compared at the end of the trial.
Upon completion, the group that consumed CPJ showed reductions in blood pressure and serum triglyceride levels — a known risk factor for cardiovascular diseases. There was also an increase in the amount of high density lipoprotein-cholesterol (good cholesterol) and a decrease in the triglyceride to high-density lipoprotein-cholesterol ratio. However, an increase was observed in levels of low-density lipoprotein-cholesterol (bad cholesterol). No adverse events or complications arose from CPJ consumption during the study period.

Randomised Controlled Trial Insulin Resistance Obesity PCOS
In this randomized, controlled, triple-blind, parallel trial study, patients diagnosed with Polycystic Ovarian Syndrome (92 in total) were grouped into four groups of 23. The three treatment groups received 2 litres of synbiotic pomegranate juice (SPJ), pomegranate juice (PJ), and a synbiotic beverage (SB) on a weekly basis. The control group was given a placebo beverage weekly. The primary focus of this trial was to observe any changes in insulin resistance, with secondary outcomes including fasting blood sugar, insulin sensitivity, testosterone, luteinizing hormone, follicle-stimulating hormone, body mass index, and waist and hip circumference comparisons, from baseline to the end of the trial.
After finishing the trial, analyses of the remaining 86 patients indicated noticeable improvement in insulin resistance, mainly in the SPJ and SB groups. The same groups also showed a significant increase in insulin sensitivity and an overall decrease in insulin. The SPJ and SB groups also saw significant reductions in body mass index, weight, and waist circumference. Lastly, there was a noteworthy decrease in testosterone levels within the SPJ and SB groups. However, no significant changes were found in fasting plasma glucose, luteinizing hormone, and follicle-stimulating hormone in any of the groups.

Randomised Controlled Trial Cardiovascular Disease High Blood Pressure PCOS
In this double-blind randomised study over 8 weeks, participants were given 300ml/day of either plain pomegranate juice, a synbiotic beverage, a synbiotic pomegranate juice, or a placebo beverage. Biochemical measures such as lipid profile, total antioxidant capacity, malondialdehyde, and high sensitivity C-reactive protein, as well as blood pressure were evaluated at the start and the end of the trial.
Participants who consumed pomegranate juice, the synbiotic beverage or the synbiotic pomegranate juice saw positive changes in their lipid profiles, oxidative stress markers, inflammation indicators and blood pressure levels. Specifically, total cholesterol was lower for those who consumed the synbiotic beverage, while bad cholesterol (LDL-c) was reduced in the synbiotic and synbiotic pomegranate juice groups, and good cholesterol levels (HDL-c) were increased in the plain pomegranate juice and the synbiotic pomegranate juice groups. As for oxidative stress and inflammation, malondialdehyde was lower and total antioxidant capacity was increased in the pomegranate juice and synbiotic pomegranate juice groups. High sensitivity C-reactive protein decreased in the pomegranate juice group. Blood pressure was lower among those who consumed both the synbiotic pomegranate juice and plain pomegranate juice compared to those who had the placebo.
