Abstract
This cross-sectional study examines the Doi-Alshoumer PCOS clinical phenotype classification in relation to measured clinical and biochemical characteristics of women with polycystic ovary syndrome (PCOS). Two cohorts of women (Kuwait and Rotterdam) diagnosed with PCOS (FAI > 4.5%) were examined. These phenotypes were created using neuroendocrine dysfunction (IRMA LH/FSH ratio > 1 or LH > 6 IU/L) and menstrual cycle status (oligo/amenorrhea) to create three phenotypes: (A) neuroendocrine dysfunction and oligo/amenorrhea, (B) without neuroendocrine dysfunction but with oligo/amenorrhea, and (C) without neuroendocrine dysfunction and with regular cycles. These phenotypes were compared in terms of hormonal, biochemical, and anthropometric measures. The three suggested phenotypes (A, B, and C) were shown to be sufficiently distinct in terms of hormonal, biochemical, and anthropometric measures. Patients who were classified as phenotype A had neuroendocrine dysfunction, excess LH (and LH/FSH ratio), irregular cycles, excess A4, infertility, excess T, highest FAI and E2, and excess 17αOHPG when compared to the other phenotypes. Patients classified as phenotype B had irregular cycles, no neuroendocrine dysfunction, obesity, acanthosis nigricans, and insulin resistance. Lastly, patients classified as phenotype C had regular cycles, acne, hirsutism, excess P4, and the highest P4 to E2 molar ratio. The differences across phenotypes suggested distinct phenotypic expression of this syndrome, and the biochemical and clinical correlates of each phenotype are likely to be useful in the management of women with PCOS. These phenotypic criteria are distinct from criteria used for diagnosis.

Abstract
OBJECTIVES Polycystic ovary syndrome (PCOS) is one of the most common endocrinopathy disorders in premenopausal women, which is characterized by hyperandrogenemia, anovulation, and polycystic ovarian morphology (PCOM). Time-restricted feeding (TRF) is a new intermittent restriction dietary pattern, which has been shown to have positive benefits on obesity and glycolipid metabolism disorders. We aimed to explore the effect of the feeding regimen (ad libitum vs. TRF) on the glycolipid metabolism and reproductive endocrine disorders in a PCOS mouse model. METHODS PCOS mouse model was induced by continuous subcutaneous administration of dihydrotestosterone for 21 days. Mice were fed a high-fat diet (HFD) for 8 weeks on an ad libitum or time- restricted diet (from 10:30 p.m. to 6:30 a.m.). RESULTS Compared to control mice, PCOS mice that received TRF treatment had significantly lower body weight, reduced adiposity, lower area under the curve (AUC) of glucose response in the oral glucose tolerance test (OGTT), and lower AUC in the insulin tolerance test (ITT). TRF also ameliorated lipid metabolism, as shown by a reduction in plasma lipid profiles (triglycerides and cholesterol) and the triglyceride content in the liver of PCOS mice. In terms of reproduction, the plasma androgen level, plasma estrogen (E2) level, and luteinizing hormone (LH)/follicle stimulating hormone (FSH) ratio in PCOS mice were significantly reduced after 8 weeks of TRF treatment. In addition, ovarian histology showed that TRF inhibits cyst formation and promotes corpus luteum formation. CONCLUSION In conclusion, TRF improved metabolic and endocrine profiles in mice with PCOS.

Abstract
Hirsutism, acne, alopecia, and oligo-amenorrhea are clinical expressions of hyperandrogenism, one of the most frequent endocrine disorders in women of reproductive age. Women referred to our endocrine clinics for skin symptoms of hyperandrogenism underwent a laboratory workup to evaluate hormone measurements and received antiandrogen therapy. We retrospectively analyzed the outcome of 228 consecutive patients investigated over 6 years.Patients with hirsutism had higher levels of androstenedione, dehydroepiandrosterone sulfate (DHEAS), and salivary testosterone; lower levels of sex hormone-binding globulin (SHBG); and a higher prevalence of oligo-amenorrhea than patients with alopecia, while patients with acne showed intermediate values. Hirsutism score correlated positively with androstenedione, DHEAS, and salivary testosterone, and correlated negatively with SHBG; salivary testosterone showed the highest correlation coefficient. Total testosterone was not significantly different among patients with hirsutism, alopecia, or acne, and did not significantly correlate with hirsutism score. Hirsutism and oligo-amenorrhea were the most sensitive symptoms of hyperandrogenism, and no androgenic parameter alone allowed us to identify all cases of hyperandrogenism.Patients of central European origin sought consultation with milder hirsutism scores than patients of southern European origin. There was, however, no difference in the clinical-biological correlation between these groups, arguing against differences in skin sensitivity to androgens.Polycystic ovary syndrome, defined as hyperandrogenism (hirsutism or elevated androgens) and oligo-amenorrhea, was diagnosed in 63 patients (27.6%), an underestimate compared with other reports that include systematic ovarian ultrasound studies. Neither pelvic ultrasound, used in a limited number of cases, nor the luteinizing hormone/follicle-stimulating hormone ratio helped to distinguish patients with polycystic ovary syndrome from the other diagnostic groups. These included hyperandrogenism (hirsutism or elevated androgens) and eumenorrhea (101 patients; 44.3%); normal androgens (acne or alopecia and eumenorrhea) (51 patients; 22.4%); isolated low SHBG (7 patients; 3.1%); nonclassical congenital adrenal hyperplasia (4 patients; 1.8% of total, 4.9% of patients undergoing cosyntropin stimulation tests); and ovarian tumor (2 patients; 0.9%).Ethinylestradiol and high-dose cyproterone acetate treatment lowered the hirsutism score to 53.5% of baseline at 1 year, and was also effective in treating acne and alopecia. The clinical benefit is ascribed to the peripheral antiandrogenic effect of cyproterone acetate as well as the hormone-suppressive effect of this combination. Salivary testosterone showed the most marked proportional decrease of all the androgens under treatment. Cost-effectiveness and tolerance of ethinylestradiol and high-dose cyproterone acetate compared well with other antiandrogenic drug therapies for hirsutism. The less potent therapy with spironolactone only, a peripheral antiandrogen without hormone-suppressive effect, was effective in treating isolated alopecia in patients with normal androgens.

Abstract
It is reported that the incidence of clinical and biochemical hyperandrogenism may be lower in Japanese patients with PCOS. Hyperandrogenism is included as a referential but not as an essential factor in the diagnostic criteria of the Japanese Society of Obstetrics and Gynecology (JSOG 1993). However, some patients with the typical clinical features of PCOS are not diagnosed with PCOS using JSOG 1993 criteria because they do not have a high LH level, which is defined as essential for diagnosis. In this study, we compared total testosterone (T) levels between Japanese patients with PCOS diagnosed using the JSOG 1993 criteria and normal menstrual women (controls). Fifty controls and 46 patients with PCOS were enrolled in this study. Furthermore, we evaluated the sensitivity and specificity of each cut-off value of T. The mean T level of patients with PCOS was significantly higher than that of the control (86 +/- 48 vs 68 +/- 46, P<0.01), and the prevalence rates of hyperandrogenism (T >114 ng/dL; defined as the mean +2SD of the control) were 10.2% in patients with PCOS and 4% in controls. The area under the ROC curve of T was 0.72, and there was no decision threshold to diagnose PCOS by T alone with both high sensitivity and high specificity. If the threshold is set as 110 ng/dL in order to gain high specificity, 94% of women whose serum level passed the threshold will be patients with PCOS. Although T should not be used as an independent essential factor of Japanese PCOS, it might be useful as a complementary factor in order to diagnose patients who have typical clinical features of PCOS but does not fulfill the JSOG 1993 criteria for PCOS.

Abstract
OBJECTIVE Neuroendocrine dysfunction in polycystic ovary syndrome (PCOS) was addressed by studying the steroid hormone changes in women with PCOS with either high or normal LH levels leading to inferences regarding the primacy of elevated LH in the pathophysiology of PCOS. METHODS A cross-sectional study was designed in an academic clinical facility involving 234 women with PCOS. Patients were divided into two groups based on an LH/FSH ratio < or >1 and hormonal and metabolic studies were performed in both groups. Factors were determined by binomial logistic regression that predicted group membership of these women. RESULTS Higher follicular phase estradiol (E2) and androstenedione (A4) levels as well as greater insulin sensitivity were the only factors that predicted the presence of neuroendocrine dysfunction with elevated A4 being necessary for neuroendocrine dysfunction. CONCLUSIONS It was concluded that uncoupling of hypothalamic E2 inhibition by elevated ovarian A4 associated with E2 related sensitization of pituitary LH leads to neuroendocrine dysfunction in PCOS.

Abstract
BACKGROUND Women with polycystic ovarian syndrome (PCOS) commonly consult endocrinologists or gynaecologists and it is not known whether these specialty groups differ in their approach to management. OBJECTIVE To compare the investigation, diagnosis and treatment practices of endocrinologists and gynaecologists who treat PCOS. DESIGN AND SETTING A mailed questionnaire containing a hypothetical patient's case history with varying presentations--oligomenorrhoea, hirsutism, infertility and obesity--was sent to Australian clinical endocrinologists and gynaecologists in teaching hospitals and private practice. RESULTS Evaluable responses were obtained from 138 endocrinologists and 172 gynaecologists. The two specialty groups differed in their choice of essential diagnostic criteria and investigations. Endocrinologists regarded androgenization (81%) and menstrual irregularity (70%) as essential diagnostic criteria, whereas gynaecologists required polycystic ovaries (61%), androgenization (59%), menstrual irregularity (47%) and an elevated LH/FSH ratio (47%) (all P-values < 0.001). In investigation, gynaecologists were more likely to request ovarian ultrasound (91%vs. 44%, P < 0.001) and endocrinologists more likely to measure adrenal androgens (80%vs. 58%, P < 0.001) and lipids (67%vs. 34%, P < 0.001). Gynaecologists were less likely to assess glucose homeostasis but more likely to use a glucose tolerance test to do so. Diet and exercise were chosen by most respondents as first-line treatment for all presentations. However, endocrinologists were more likely to use insulin sensitizers, particularly metformin, for these indications. In particular, for infertility, endocrinologists favoured metformin treatment whereas gynaecologists recommended clomiphene. CONCLUSIONS There is a lack of consensus between endocrinologists and gynaecologists in the definition, diagnosis and treatment of PCOS. As a consequence, women may receive a different diagnosis or treatment depending on the type of specialist consulted.
