Abstract
Polycystic ovary syndrome is the most common endocrine disorder in women of reproductive age, which is still incurable. However, the symptoms can be successfully managed with proper medication and lifestyle interventions. Despite its prevalence, little is known about its etiology. In this review article, the up-to-date diagnostic features and parameters recommended on the grounds of evidence-based data and different guidelines are explored. The ambiguity and insufficiency of data when diagnosing adolescent women have been put under special focus. We look at some of the most recent research done to establish relationships between different gene polymorphisms with polycystic ovary syndrome in various populations along with the underestimated impact of environmental factors like endocrine-disrupting chemicals on the reproductive health of these women. Furthermore, the article concludes with existing treatments options and the scopes for advancement in the near future. Various therapies have been considered as potential treatment through multiple randomized controlled studies, and clinical trials conducted over the years are described in this article. Standard therapies ranging from metformin to newly found alternatives based on vitamin D and gut microbiota could shine some light and guidance toward a permanent cure for this female reproductive health issue in the future.

Abstract
In this prospective study, seventy-six patients (PCOS group; n = 36, multifollicular ovary group; n = 40) were evaluated by 2-D and 3-D ultrasonography. VOCAL programme, echogenicity, number of follicles and blood flow parameters were evaluated. The patients with PCOS had a higher total ovarian volume, mean stromal volume and stromal echogenicity (18.6 ± 4.75 to 10.2 ± 3.4 p < .01; 12.23 ± 2.53 to 5.02 ± 2.44 p = .02; score 1:28 to 10 p < .01, respectively). There was no statistically significant difference in terms of mean RI and PI values between the groups (p > .05). 3 D power Doppler parameters included VI, FI, and VFI values of the patients with PCOS were higher when compared to those of the patients with multifollicular ovary (3.82 ± 2.65 to 1.78 ± 1.2, p < .01; 50.76 ± 4.45 to 40.6 ± 3.64, p = .03; and 2.34 ± 1.02 to 1.12 ± 0.65, p = .02, respectively). Our results revealed that total ovarian volume, stromal volume and echogenicity; VFI, VI, and FI could be useful for differential diagnosis in women with PCOS and multifollicular ovaries.Impact statementWhat is already known on this subject? Ultrasonography is considered the new diagnostic tool for PCOS. Enlarged ovaries with multiple small follicles peripherally located around increased ovarian stroma with increased stromal echogenicity are the sonographic features of polycystic ovaries.What do the results of this study add? 3-D Doppler ultrasonography may be more specific in the determination of multifollicular and polycystic ovaries when compared to RI and PI in 2-D Doppler ultrasonography. Moreover, 3-D power Doppler ultrasonography could be useful for differential diagnosis in women with PCOS and multifollicular ovaries.What are the implications of these findings for clinical practice and/or further research? In clinical practice, the differentiation of multifollicular ovaries and polycystic ovaries (PCO) is difficult with the use of 2-D sonography alone. Therefore, 3-D ultrasound and power Doppler may also be used in addition to 2-D ultrasound for the differentiation of multifollicular ovaries and PCO.

Abstract
Polycystic ovary syndrome is a common endocrinological condition which is found to be prevalent in 5-10% of women of reproductive age. Historically, a combination of anovulation and androgen excess was considered a hallmark in the diagnosis of polycystic ovary syndrome. Addition of ultrasound features of polycystic ovary syndrome has improved the detection of variation in the polycystic ovary syndrome phenotype. Despite the widespread use of consensus diagnostic criteria, there remain several unresolved controversies in the diagnosis of polycystic ovary syndrome. Difficulty arises in methods of assessment and types of androgens to be measured to detect biochemical hyperandrogenism, setting a cut-off value for the diagnosis of clinical hyperandrogenism, setting an ultrasound threshold of antral follicle count to diagnose polycystic ovaries and also diagnosing this condition in adolescence where there is no clear definition for 'irregular cycles'. This article looks at various controversies in the diagnosis of polycystic ovary syndrome.

Abstract
BACKGROUND There is a growing debate on the opportunity of improving the understanding in the diagnosis and management of polycystic ovary syndrome (PCOS). OBJECTIVE This review article summarizes recent research related to the definition of polycystic ovary syndrome (PCOS). METHODS Review of the recent literature on the topic. RESULTS New ideas on the definition of hyperandrogenism, based on new scientific data and clinical perspectives are presented. (i) In fact, recent studies have pointed out the need to improve the concept of androgen excess by using a larger androgen profile, rather than simply measuring the testosterone blood levels. (ii) Due to the poor correlation between androgen blood levels and the degree of hirsutism, it is proposed that the definition of hyperandrogenism should be based on the presence of blood androgen excess and hirsutism, considered separately, because their pathophysiological mechanisms may differ according to the different phenotypes of PCOS. (iii) The potential role of obesity in favoring the development of PCOS during adolescence is also discussed and the concept of "PCOS secondary to obesity" is developed. (iv) Finally, the need for greater appropriateness in the evaluation of possible coexistence is highlighted, in patients with PCOS who have fasting or glucose-stimulated very high insulin levels, or severe insulin-resistant states. CONCLUSIONS Based on what was discussed in this review, we believe that there are margins for modifying some of the current criteria that define the various PCOS phenotypes.

Abstract
Antral follicle count (AFC) has been shown to be a reliable marker for ovarian reserve. The aims of this study were to create an age-related normogram for AFC in infertile women with polycystic ovary syndrome (PCOS) and to compare age-related decline in AFC between infertile women with and without PCOS. A retrospective cohort study was conducted. Of a total of 4956 women, 619 women fit criteria for PCOS. In those with PCOS, there were large variations in the AFC between the 10th and 90th percentiles in all age groups. The rate of decline in AFC among women with PCOS was linear, while in those with non-PCOS, it was exponential until 30 years of age, and then became similar to that of PCOS. The rate of follicle loss per year was significantly slower in PCOS women compared with that in non-PCOS women. In both groups, the fastest period of follicle loss was between the ages of 18 and 30. The average follicle loss was 0.8 follicles/year in PCOS women and 1.7 follicles/year in those without PCOS (P<0.001). This study concludes that age-related decline in AFC among women with PCOS is slower than in those without PCOS. Antral follicle count (AFC) has been shown to be a reliable marker for ovarian reserve. The aims of this study were to create an age-related normogram for AFC in women with polycystic ovary syndrome (PCOS), and to compare age-related decline in AFC between women with and without PCOS. A retrospective cohort study was conducted. All patients underwent a baseline transvaginal ultrasound that was performed on day 2-4 of the menstrual cycle. The total number of antral follicles of 2-9mm in diameter was recorded. Of total 4956 women, 619 women fit criteria for PCOS. In those with PCOS, there were large variations in the AFC between the 10th 90th percentiles in all age groups. The rate of decline in AFC among women with PCOS was linear; while in those with non-PCOS, it was exponential until 30 years of age, and then became similar to that of PCOS. The rate of follicle loss per year was significantly slower in PCOS women compared with that in non-PCOS women. In both groups, the fastest period of follicle loss was between the ages 18-30 years. The average follicle loss was 0.8 follicles/year in PCOS women and 1.7 follicles/year in those without PCOS (P<0.001). We have concluded that age-related decline in AFC among women with PCOS is slower than in those without PCOS. Further studies are needed to determine if the AFC normogram in women with PCOS could be clinically relevant to select the optimal gonadotrophin dose for ovulation induction.

Abstract
OBJECTIVE To compare spatiotemporal image correlation-high definition flow (STIC-HDF) indices from spherical samples of ovary between women with polycystic ovary syndrome (PCOS) and normal women. METHODS This was a prospective case-control study of premenopausal women with a diagnosis of PCOS according to the Rotterdam criteria and of healthy, regularly menstruating, premenopausal women (controls) matched for age (< 35 years) and body mass index. Women were assessed in the follicular phase of the menstrual cycle by 4D STIC-HDF transvaginal ultrasound. Based on 1-cm(3) spherical sampling, we calculated for each woman the vascularization index (VI) for the most vascularized part of the ovarian stroma in all three-dimensional volumes of the 4D STIC-HDF sequence. The maximum (VI(sys)) and minimum (VI(diast)) values were assumed to represent systole and diastole, respectively, and the mean VI for all frames from one cardiac cycle was calculated. Based on these three VI values, we calculated the following indices: volumetric systolic/diastolic ratio (vS/D), volumetric resistance index (vRI) and volumetric pulsatility index (vPI), and compared them between study and control groups. RESULTS The study included 32 PCOS women (mean age, 29.6 years) and 32 controls (mean age, 30.4 years). Mean VI(sys) (26.246% vs 8.136%, P < 0.0001) and mean VI(diast) (22.242% vs 5.997%, P < 0.0001) were significantly higher in PCOS women compared with controls. Median vS/D (1.15 vs 1.33, P < 0.001), mean vRI (0.17 vs 0.30, P < 0.001) and median vPI (0.14 vs 0.28, P < 0.001) were significantly lower in PCOS women compared with controls. CONCLUSION 4D STIC-HDF indices from 1-cm(3) spherical samples of the ovaries were different between PCOS women and controls, suggesting lower impedance to flow in ovarian stromal vessels in PCOS women.

Abstract
INTRODUCTION The age-specific prevalence of polycystic ovaries (PCO), as defined by the Rotterdam criteria, among normal ovulatory women, has not yet been reported. It is also uncertain whether these women differ from their peers in the hormonal or metabolic profile. METHODS A total of 262 ovulatory Caucasian women aged 25-45 yr, enrolled in a community-based ovarian aging study (OVA), underwent transvaginal ultrasound assessment of ovarian volume and antral follicle count (AFC) in the early follicular phase and were categorized as to whether they met the Rotterdam definition of PCO by AFC (≥12 in one ovary) and/or by volume (>10 cm(3) for one ovary). The effect of age on prevalence of PCO was assessed. Serum hormones and metabolic measures were compared between women meeting each element of the Rotterdam criterion and those without PCO using age-adjusted linear regressions. RESULTS The prevalence of PCO by AFC was 32% and decreased with age. Those with PCO by AFC had lower FSH; higher anti-Müllerian hormone, estrone, dehydroepiandrostenedione sulfate, and free androgen index; and slightly higher total testosterone than those without PCO. However, slightly higher body mass index and waist circumference were the only metabolic differences. Women with PCO by volume had higher anti-Müllerian hormone and free androgen index but did not differ in any other hormonal or metabolic parameter. DISCUSSION PCO is a common, age-dependent finding among ovulatory women. These women lack the metabolic abnormalities seen in PCO syndrome. Isolated PCO in an ovulatory woman is not an indication for metabolic evaluation.
