A few studies have been reported regarding the endocrine features of asymptomatic women with PCO with conflicting data about endocrine profiling. The aim of this study was to assess whether women with PCO, but who have no symptoms of PCOS differ, endocrinologically, from women with normal ovaries.?Methods: We analysed the results of ultrasound and endocrine investigations in 576 consecutive women who attended the infertility clinic between 1993 and 1995 at the Reproductive Medicine Unit of St Mary’s Hospital, Imperial College Healthcare NHS Trust, London, UK. Results: Three hundred and twenty eight women had PCO and 248 had normal ovaries. Among the 328 women with PCO, 169 (51.5%) had PCOS according to Rotterdam criteria. The remaining women with PCO had no symptoms of the syndrome (n = 159);they had a history of regular menses, had proven ovulatory cycles and had neither clinical nor biochemical evidence of hyperandrogenism. However, these women had higher timed LH [median (IQR) 5.3 (4.2) IU/l vs 4.8 (3.4) IU/l, respectively;p = 0.044] and testosterone [2.0 (0.8) nmol/l vs 1.8 (0.8), respectively;p = 0.009] compared with women with normal ovaries (although by definition within the normal range). There was no difference in BMI or FSH between the two groups. Among the 169 women with PCOS, 45.0% (n = 76) were anovulatory without hyperandrogenism, 34.3% (n = 58) fulfilled the NIH criteria and 20.7% (n = 35) were ovulatory with hyperandrogenism. The proportion of hyperandrogenism among anovulatory women with PCO is 43.3% (58 out of 134).?Conclusions: Women with PCO, but no symptoms of the syndrome, differ endocrinologically compared with women with normal ovaries: they had higher timed LH and testosterone (although by definition within the normal range). These data suggest that despite the lack of symptoms of PCOS, women presenting to an infertility clinic with PCO represent a milder phenotype of those with overt PCOS, but fall on the same spectrum.展开更多

Methods A total of 234 PCOS patients were enrolled according to the ovary morphology and divided into three groups： 112 patients with B-polycystic ovary mor- phology （both two ovaries were PCOM, B-PCOM）, 50 with U-PCOM （only one ovary was PCOM） and 72 with N-PCOM （none was PCOM）. There were 39 infertile women without PCOS as control group. Data were analyzed by using SPSS 15.0 software. ResuIts There was no statistical difference in body mass index （BM1） among the three groups of PCOS. The endometrial thickness increased in patients with B-PCOM and decreased with N-PCOM. The levels of testosterone, androstenedione and luteinizing hormone increased in PCOS groups, especially in N-PCOM patients. HOMA-IR increased, HOMA-fl, disposition index （DI） and △160/AG60 decreased in patients with N- PCOM compared with in B-PCOM and U-PCOM groups. Higher level of total choles- terol （TC） and lower level of high-density lipoprotein （HDL）-C existed in PCOS patients, especially in N-PCOM. There were positive correlations between oligo-anovulation, endometrial thickness, LH/FSH ratio, fasting insulin （FINS）, the area under curve of glucose（A UCcLu） and PCOM, while there was a negative correlation between HOMA- IR and PCOM. Conclusion There are relationships among hyperandrogenism, hyperinsulinemia, insulin resistance （IR） and ovary morphology in PCOS patients. PCOS patients with- out PCOM have more serious IR and hyperandrogenism.展开更多
