Serum gonadotropin, estrogen, and androgen levels were measured in samples obtained from 19 patients with polycystic ovarian disease (PCO) and from 10 normal women on day 2 to 4 of their menstrual cycles. In patients with PCO, the mean (plus or minus S.E.) concentration was significantly higher (P smaller than 0.001) than the concentrations found in the normal subjects for LH (35 plus or minus 4.6 vs. 12.7 plus or minus 2.6 m.I.U. per milliliter), but not for FSH (10.3 plus or minus 0.7 vs. 8.7 plus or minus 0.9 m.I.U. per milliliter). Estrone (E1) levels (92 plus or minus 4 vs. 52 plus or minus 5 pg. per milliliter) were also significantly higher (P smaller than 0.001), while estradiol (E2) concentrations (58 plus or minus 4 vs. 63 plus or minus 8 pg. per milliliter) were comparable. Testosterone (T) (468 plus or minus 41 vs. 325 plus or minus 34 pg. per milliliter, P smaller than 0.05), androstenedione (delta) (2,083 plus or minus 138 vs. 1,123 plus or minus 153 pg. per milliliter, P smaller than 0.001), and dehydroepiandrosterone sulfate (3.4 plus or minus 0.4 vs. 2.0 plus or minus 0.37 mug per milliliter, P smaller 0.02) were also significantly increased over the values in normal controls. The mean dehydroepiandrosterone (DHEA) was elevated in the patients with PCO (11.3 plus or minus 1.7 vs. 7.5 plus or minus 1.2 mug per milliliter), but was not significantly different. A positive correlation was found between LH levels and both E2 and E1 concentrations in the patients with PCO. These data show a distinct profile of gonadotropin, estrogen, and androgen levels in patients with PCO. 相似文献

Ghrelin, an endoggenous for the growth hormone secretagogue receptor, has been shown to participate in the regulation of energy homeostasis and pituitary hormone secretion. Obestatin, encoded by the same gene as ghrelin, is described as a physiological opponent of ghrelin. Ghrelin and obestatin are altered in polycystic ovary syndrome (PCOS), which is characterized by insulin resistance and pituitary hormone secretion disorder. The aim of this study was to evaluate ghrelin/obestatin imbalance in relation to insulin resistance and pituitary hormone in adolescence with PCOS. This restrospective case–control study included 33 adolescence with PCOS and 38 control adolescence. Ghrelin and obestatin concentrations in serum were determined by RIA, and the serum fasting glucose and Insulin were determined by the glucose oxidase color method and INS-EASIA. The serum LH and FSH were measured by highly specific hemiluminescence immunoassays. We found that the serum ghrelin levels and ghrelin/obestatin ratio were significant lower in PCOS group than in control group, and the serum obestatin levels were significant higher in PCOS group than in control group. The ghrelin/obestatin ratios were negatively correlation with LH/FSH ratio and insulin resistant index in PCOS group. The findings of this study suggest that ghrelin/obestatin imbalance may play a role in pathogenesis of adolescent PCOS. 相似文献

The rate of adhesion formation after ovarian electrocauterization has been described in two selective and unselective groups of patients with PCOS. The rate of this complication in the selective group was 0 from 16 ovaries and in the unselective group (5/25). However, the rate of major adnexal adhesion in the unselective group was 1 from 25 ovaries. 相似文献

目的:探讨多囊卵巢综合征(polycystic ovary syndrome,PCOS)患者子宫内膜增生(endometrial hyperplasia,EH)的发生率及相关预测因素。方法:以160例PCOS患者为研究对象,以80例因输卵管因素或男方因素不孕的非PCOS患者为对照组。研究P-COS诊断要素在EH中的作用;比较两组EH的发生率及不同亚型PCOS患者EH的发生率;研究PCOS患者临床特征与EH的关系。结果:月经稀发和高雄激素血症组的EH发生率明显增高(P均<0.05);PCOS组EH发生率明显高于对照组(18.75%vs 7.5%,P=0.021)。PCOS患者月经周期>59天或超声子宫内膜回声异常时,EH发生率显著升高(P=0.005,P=0.003)。结论:月经稀发和高雄激素血症在EH中发挥重要作用,只存在月经稀发或高雄激素血症的可疑PCOS患者亦应重视其子宫内膜病变。PCOS患者EH发生率增高,尤其是月经周期>59天或存在子宫内膜回声异常者,应高度警惕子宫内膜病变。 相似文献

AIM: To investigate the behavior and association of serum androgen and serum C-reactive protein (CRP) in patients undergoing controlled ovarian hyperstimulation (COH) for in vitro fertilization (IVF). DESIGN: Prospective, observational study.Setting. An IVF unit of an academic medical center. PATIENTS AND METHODS: Blood was drawn three times during the COH cycle from 15 patients undergoing the long gonadotropin-releasing hormone-analog protocol: the day on which adequate suppression was obtained (Day-S); the day of or prior to administration of human chorionic gonadotropin (Day-hCG); and the day of ovum pick-up (Day-OPU). Levels of sex steroids and serum CRP were compared among the three time points. RESULTS: There was a significant increase in serum ovarian androgen levels during gonadotropin treatment. After hCG administration, there was a significant increase in the levels of both serum CRP and ovarian androgens (testosterone, androstenedione), with no significant change in adrenal androgen (dehydroepiandrosterone). Significant correlations were observed between CRP and ovarian androgen levels but not with dehydroepiandrosterone sulfate or estradiol levels. CONCLUSION: In patients undergoing COH for IVF, ovarian androgen levels increase in correlation with the degree of inflammation, as reflected by CRP levels. Further studies are necessary to elucidate whether androgens play a role in or are predictive of the systemic inflammatory response in COH. 相似文献

OBJECTIVES: To evaluate the diagnostic value of 3-dimensional transrectal ultrasonography (3D-TRS) in adolescent patients with polycystic ovarian syndrome (PCOS). METHODS: Ovarian follicle number, ovarian volume, ovarian stromal area, total ovarian area, and stromal area to total area ratio (S/A) were evaluated using 3D-TRS in 75 amenorrheic, oligomenorrheic, or asymptomatic virgin patients and 25 healthy controls. Serum biochemical markers of PCOS were assayed during the early follicular phase of the menstrual cycle in menstruating patients and controls, and on a randomly selected day in amenorrheic patients. RESULTS: When assessing the delicate structure of the ovary in virgin patients, 3D-TRS was convenient, accurate, specific, sensitive, and more reliable overall than transabdominal ultrasonography. Ovarian stromal area and S/A ratio were significantly greater in patients with PCOS than in controls, and also in the patients who had ultrasonically diagnosed polycystic ovaries without clinical or biochemical evidence of PCOS. The S/A ratio was the studied variable most significantly correlated with androgen levels. CONCLUSIONS: These findings indicated that, in adolescent patients, 3D-TRS combined with transabdominal ultrasonography can improve the precision of the diagnosis of PCOS. The S/A ratio may become the ultrasonographic diagnostic marker for PCOS. 相似文献

Hyperinsulinemia in polycystic ovary syndrome correlates with increased cardiovascular risk independent of obesity 总被引:1,自引:0,他引:1
OBJECTIVE: To assess the role of insulin resistance, independent of obesity, in determining cardiovascular risk among women with the polycystic ovarian syndrome (PCOS). DESIGN: Cross-sectional study examining the relationships between hyperinsulinemia, composite cardiovascular risk scores, and prevalence of individual risk factors among lean and obese women with PCOS and healthy controls. SETTING: University-based tertiary care outpatient endocrinology clinic. PATIENT(S): 57 women with clinically defined PCOS and 45 unselected healthy age-matched controls. INTERVENTION(S): Clinical and anthropomorphic measurements and laboratory determinations of insulin and lipid levels. MAIN OUTCOME MEASURE(S): Fasting serum insulin and a cardiovascular risk score. RESULTS: Hyperinsulinemic women with PCOS carried more cardiovascular risk than their normoinsulinemic counterparts, who in turn had more risk than the control women (P=.004 by analysis of covariance). In addition to the lipid changes expected with insulin resistance (high triglyceride and low HDL cholesterol levels), there was an excess of LDL cholesterol among the women with PCOS (P=.006 by analysis of covariance). Across the range of body mass index, women with PCOS had greater insulin resistance than controls, suggesting that PCOS itself and body mass index both contribute to the observed insulin resistance. CONCLUSIONS: Our data support the hypothesis that insulin resistance in PCOS is a determinant of overall cardiovascular risk independent of obesity. The mechanism of this relationship remains uncertain and is the subject of ongoing research. 相似文献

Saliva as a matrix for measuring free androgens: comparison with serum androgens in polycystic ovarian disease. 总被引:2,自引:0,他引:2
We report a simple and direct procedure for the measurement of circulating free testosterone concentrations by using saliva as a matrix rather than serum. There is a close correlation between saliva testosterone values measured by radioimmunoassay, calculated values of free testosterone, and free testosterone estimated by equilibrium dialysis. Our method is direct and has the advantage that the biologic fluid can be obtained routinely by noninvasive techniques outside the clinic during a course of therapy. We also show that a single saliva value is of greater diagnostic use than any of the currently used androgen assays. Testosterone was found to be elevated in the saliva of 17 infertility patients diagnosed as having polycystic ovarian syndrome, 14 of these patients were hirsute. 相似文献

Changes of bioactive luteinizing hormone after laparoscopic ovarian cautery in patients with polycystic ovarian syndrome 总被引:1,自引:0,他引:1

The serum levels of bioactive luteinizing hormone (LH), immunoreactive LH, follicle-stimulating hormone, androstenedione (A), and testosterone (T) were determined in nine anovulatory women with polycystic ovarian syndrome (PCOS) before and after laparoscopic ovarian cautery. Eight ovulated spontaneously and three conceived after treatment. Before treatment, the mean (+/- SEM) levels of bioactive LH, immunoreactive LH, A, and T were 51.4 +/- 8.6 mIU/mL, 36.0 +/- 4.5 mIU/mL, 1.98 +/- 0.35 ng/mL, and 1.18 +/- 0.13 ng/mL, respectively, which were significantly higher than those of five control women (19.2 +/- 1.6 mIU/mL, 21.4 +/- 1.2 mIU/mL, 0.54 +/- 0.03 ng/mL, 0.28 +/- 0.03 ng/mL). After treatment, the mean levels of these hormones had significantly decreased. Decreases in the levels of these hormones by laparoscopic ovarian cautery in women with PCOS may result in both restoration of the ovulatory cycle and achievement of pregnancy. 相似文献

Gonadotropin-releasing hormone (0.025 microgram/kg) was administered intravenously in a pulsatile fashion to four subjects with polycystic ovary syndrome for a total of six cycles. Five of the six cycles culminated in ovulation, although in one course the response occurred too early to be attributed to the therapy alone. No pregnancies resulted. All luteal phases were of normal duration, but progesterone production as manifested by serum progesterone determination was deficient in some. If additional investigation confirms these preliminary findings, this form of therapy may offer a safe and economic alternative for anovulatory patients refractory to clomiphene citrate therapy. The response of the four subjects suggests that pulsatile gonadotropin-releasing hormone administration may override hypothalamic-pituitary dysfunction and result in ovulatory menstrual cycles. 相似文献

OBJECTIVE: To assess pain control in patients with polycystic ovary syndrome (PCOS) who are undergoing ovarian drilling during minilaparoscopy under local anesthesia and conscious sedation and to evaluate the efficacy of this protocol compared with the traditional approach in terms of operative and discharge times, subsequent ovulation, and pregnancy. DESIGN: Prospective randomized study. SETTING: University hospitals and private day-surgery unit. PATIENT(S): Sixty-two infertile women with PCOS. INTERVENTION(S): Group A underwent minilaparoscopic ovarian drilling under local anesthesia and conscious sedation. Group B (control group) was treated with traditional ovarian drilling by laparoscopy under general anesthesia. MAIN OUTCOME MEASURE(S): Intraoperative pain score in group A. Hormonal profile before and after surgery, operative and discharge times, postoperative analgesic requirements, and reproductive follow-up in both groups. RESULT(S): Group A showed a good intraoperative pain score. The hormonal profile after surgery did not differ between groups A and B. Operative times were also similar for both groups. The number of patients discharged within 2 hours after surgery was significantly higher in group A. The need for postoperative analgesics was significantly higher in group B. No statistically significant differences were noted between the groups in terms of pregnancy and ovulation rates. CONCLUSION(S): Intraoperative and postoperative local anesthesia plus conscious sedation allows outpatient bilateral ovarian drilling by minilaparoscopy to be performed without general anesthesia. The high pregnancy rates, the simplicity of the method, and the faster discharge time offer a new option for patients with PCOS who are resistant to clomiphene citrate. Moreover, ovarian cauterization can be performed simultaneously with a diagnostic minilaparoscopy and integrated into the infertility workup of these patients. 相似文献

Objective.?The present study aimed to evaluate the effect of metformin exposure during pregnancy on neonates of polycystic ovarian syndrome (PCOS) patients.Method.?Neonatal outcomes of 33 women with PCOS treated with metformin during pregnancy were compared to neonatal outcomes of 66 normal healthy women in a retrospective case–control study.Results.?The mean birth weight percentile of neonates exposed to metformin in utero during the first trimester was significantly lower than that of neonates delivered to normal healthy matched controls. After controlling for pregnancy complications, this observation became only marginally statistically significant.Conclusion.?Although metformin is an attractive option for induction of ovulation in PCOS patients, there is a need for more evidence related to its safety during pregnancy. 相似文献

Impact of adrenal versus ovarian androgen ratio on signs and symptoms of polycystic ovarian syndrome
《Gynecological endocrinology》2013,29(8):611-614
The aim of this study was to examine the effect of adrenal versus ovarian androgen (dehydroepiandrosterone sulfate/total testosterone [DHEAS/TT]) on clinical presentation and related metabolic disturbances in Turkish women with polycystic ovarian syndrome (PCOS). Two hundred eighty PCOS cases were taken into the study. For all cases, the DHEAS/TT ratio was calculated. The median value of this ratio was 4.40. Patients with an androgen ratio lower than 4.40 were included in Group 1 and cases with a ratio higher than 4.40 were Group 2. The two groups were compared in terms of hormonal, biochemical and clinical parameters. Body mass index and waist circumference were lower, the Ferriman–Gallwey score was higher and the cycle length was shorter in Group 2. High DHEAS level was associated with better lipid profiles and lower levels of inflammatory markers, meaning good metabolic control in these women, in spite of increased hirsutism rates. In patients with PCOS, both androgens are usually high in proportion to each other. Therefore, it would be more meaningful to use the DHEAS/TT ratio for an assessment of the metabolic and phenotypic effects of PCOS. 相似文献

Leptin, particularly in its free form, is deeply involved in the regulation of energy balance. Insulin was suggested to influence plasmatic leptin levels and soluble leptin receptor in humans. However, this study indicates that metformin treatment, although improving insulin levels, does not exert a significant effect on either total leptin level or free leptin index in obese women with hyperinsulinemia and PCOS. 相似文献

This prospective cohort study was conducted on 80 patients with clomiphene citrate (CC)-resistant polycystic ovary syndrome undergoing laparoscopic ovarian drilling (LOD). Pre- and post-LOD ovarian reserve parameters (anti-Mullerian hormone: AMH, ovarian volume: OV, and antral follicle count: AFC) and ovarian stromal blood flow indices (Vascularization index: VI, flow index: FI, and vascularization flow index: VFI) were measured to explore the effect of LOD and to find out the correlation between serum AMH and different clinical, hormonal, and ultrasonic variables. There was a highly significant reduction of the serum AMH (p?.001) after LOD with significant reduction in OV, AFC and vascular indices (VI, FI and VFI) of the right and left ovaries (p?.05). LOD significantly reduced ovarian reserve parameters (AMH, OV and AFC) and ovarian stromal blood flow indices (VI, FI and VFI) with no observed correlation between AMH levels and Doppler indices. 相似文献
