However, whether IR in patients without PCOS should be treated remains uncertain. This study aims to clarify whether IR in patients without PCOS affects the outcomes of in-vitro fertilization-embryo transfer (IVF-ET) and pregnancy. Methods: Between January 2011 and December 2013, we retrospectively reviewed the medical records of 116 non-PCOS patients who underwent the first IVF–ET cycle. IR was calculated using the homeostasis model assessment (HOMA) index [HOMA-IR = (insulin × glucose)/405]. A HOMA index of >2.5 was used to indicate IR. Based on the HOMA index calculation, 28 patients were IR(+) and 88 patients had normal insulin sensitivity. We retrospectively compared the response with controlled ovarian hyperstimulation, retrieved oocytes number, fertilization rates, pregnancy rate, live birth rates, and gestational diabetes mellitus (GDM) incidence. Results: There were no significant differences in human menopausal gonadotropin administration, peak estradiol, retrieved oocyte number, fertilized embryo number, good quality embryo number, implantation rate, clinical pregnancy rate, miscarriage rate, delivery rate, or ovarian hyperstimulation syndrome and GDM incidences between the groups. Conclusion: IR in non-PCOS patients has no effect on IVF-ET outcomes or perinatal prognosis.展开更多

In addition to adverse perinatal outcomes, it may lead to permanent health problems for the mother, such as type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD), while increasing the risk of future obesity, CVD, T2DM and GDM in the child. Approximately 15% of women seek fertility treatment. Over the last decade, it has come to attention that patients with an infertility history are more prone to having GDM during their pregnancies, and this review examines the relationship between GDM and infertility. The elevated estrogen, progesterone, leptin, placental lactogen and growth hormone are the main reasons for increased insulin resistance during pregnancy. Despite some confounding factors in the mechanism of GDM in patients with an infertility history, infertility treatment increases the risk, according to numerous studies. The obesity epidemic and associated disorders have become a significant public health concern worldwide. Lifestyle modification for weight loss before pregnancy is encouraged, but there is no strong evidence for improvement in perinatal results. GDM, infertility and infertility treatment have a potential risk of alteration in the embryo’s environment and cause epigenetic reprogramming, which may be inherited to the next generation. The fertility treatment impacts the patient’s and offspring’s health. Patients should be informed about the risks so that they consent and get involved in the decision. Infertility treatment may be accepted as a reason for high-risk pregnancy, and patients can be screened for GDM in early pregnancy.展开更多

The trial investigators did not recommend acupuncture for the women with PCOS or IVF based on their findings. This paper raises the concern that the findings that acupuncture did not increase LBR for women with PCOS or undergoing IVF may be the result of methodological flaws in the studies and unintended bias such as use of an invalid control intervention and underestimation of the true acupuncture effect. Therefore, their findings may not be a valid reflection of acupuncture’s effect in improving LBR in women with these clinical conditions.展开更多

Methods Sixty-six patients with PCOS and undergoing IVF-ET were divided into two groups randomly, including an observation group （34 cases） and a control group （32 cases）. Ethinylestradiol and cyproterone acetate tablets and gonadotropin-releasing hormone agonist were administered for long-program superovulation in either group. In the observation group, the intervention of EA was applied to Guānyuán （关元 CV 4）, Zhōngjí （中极 CV 3）, Sānyīnjiāo （三阴交 SP 6）, Zǐgōng （子宫 EX-CA 1） and Tàixī （太溪 KI 3） additionally for 30 min, once daily, 1 menstrual cycle before controlled ovarian hyperstimulation （COH） and during COH. The pregnant outcome, evaluation of kidney deficiency syndrome, blood hormone level on the day of human chorionic gonadotropin injection and the concentrations of stem cell factor （SCF） in the serum and follicular fluid on the day of oocyte collection were compared between the two groups. Results The score of kidney deficiency symptoms was reduced remarkably after treatment in either group and the improvement in the observation group was superior to that in the control group （P0.01）. The fertilization rate [（76.25？±？20.33）% vs （66.34？±？15.44）%], cleavage rate [（98.66？±？3.70）% vs （94.47？±？9.45）%] and the rate of high-quality embryos [（60.20？±？22.20）% vs （50.55？±？16.15）%] in the observation group were all superior to those in the control group separately （all P0.05）. Clinical pregnancy rate （46.67%, 14/30） in the observation group was higher than that （37.93%, 11/29） in the control group, but without statistical difference （P0.05）. SCF concentrations in the serum and follicular fluid on the day of oocyte collection in the observation group were higher obviously than those in the control group （both P0.05）. Conclusion Electroacupuncture plays an active role in the pregnant outcomes of PCOS patients undergoing IVF-ET and it can relieve the symptoms of kidney deficiency in terms of TCM and improve clinical pregnant rate. The mechanism is relevant to the overall adjustment of organic endocrinal system and the local micro-environment of ovary and the improvement of oocyte quality through the up-regulation of SCF concentration.展开更多

Methods: In the retrospective cohort study, a total of 1074 patients with PCOS undergoing IVF between April 2010 and May 2017 in two reproductive medicine centers, respectively in eastern China(Women's Hospital, School of Medicine, Zhejiang University, Zhejiang Province) and in southern China(Maternal and Child Health Care Hospital of Liuzhou, Guangxi Province), were included. The patients were divided into four groups according to the recommended Chinese BMI cut-off points: underweight(BMI<18.5kg/m^2), normal weight(18.5kg/m^2≤BMI<24.0kg/m^2), overweight(24.0kg/m^2≤BMI<28.0kg/m^2), and obese(BMI≥28.0kg/m2). The basic characteristics of the PCOS patients, the details of IVF treatment, and the pregnancy outcomes were collected. Main results: There were no significant differences among the normal weight, overweight, and obese PCOS patients undergoing IVF on the biochemical pregnancy rate, clinical pregnancy rate, miscarriage rate, live birth rate, or term delivery rate(P>0.05), although the overweight and obese PCOS patients required more gonadotropin(Gn)(P<0.001) as well as longer stimulation period(P<0.001), and got less retrieved oocytes(P<0.05) and fertilized oocytes(P<0.05). The underweight PCOS patients required less Gn(P<0.05) and achieved higher live birth rate and term delivery rate(P<0.05), compared with the normal weight PCOS patients. Conclusions: High BMI had no negative effects on the outcomes of IVF in Chinese patients with PCOS; however, the conclusion may seem a little limited due to the retrospective design and the potential bias.展开更多

文摘目的探讨行体外受精-胚胎移植(in vitro fertilization and embryo transfer,IVF-ET)助孕的多囊卵巢综合征(polycystic ovary syndrome,PCOS)患者血清中补体C1q/肿瘤坏死因子相关蛋白9(complement C1q/tumour necrosis factor-related protein 9,CTRP9)、抗苗勒管激素(anti-mullerian hormone,AMH)对治疗结果的预测价值。方法选取2022年3月—2023年7月于重庆医科大学附属第一医院生殖中心行IVF-ET的85例PCOS患者。根据妊娠结局分为临床妊娠组43例与临床未妊娠组42例。记录2组患者的一般资料,测定血清CTRP9和AMH水平,分析其与妊娠结局的关系。结果临床未妊娠组血清CTRP9为(290.19±58.97)ng/mL,AMH为3.39(2.09,5.42)ng/mL,均低于临床妊娠组的(413.63±89.56)ng/mL、7.42(5.45,9.90)ng/mL(P<0.05)。血清CTRP9、AMH水平、优胚数是PCOS患者IVF-ET妊娠成功的保护因素(P<0.05)。血清CTRP9预测行IVF-ET的PCOS患者妊娠成功的敏感度与特异度为74.40%和90.50%,曲线下面积(area under the curve,AUC)值为0.836;血清AMH预测敏感度与特异度为83.70%和73.80%,AUC值为0.859;血清CTRP9和AMH联合预测的敏感度和特异度分别为88.40%和92.90%,AUC值为0.924,高于单独使用CTRP9或AMH预测的价值。结论血清CTRP9、AMH与PCOS患者IVF-ET治疗结局密切相关,且与单一指标检测比较,两者联合检测可提高预测价值。
