卵巢对控制性超排卵反应的回顾性研究 总被引:4,自引:1,他引:3
目的 探讨在体外受精-胚胎移植中卵巢对控制性超排卵的反应性.方法 回顾性分析57例实施体外受精-胚胎移植的治疗周期,病例组43例,均为因输卵管因素不孕者;对照组14例,因男性因素不孕或多囊卵巢综合征者.比较两组血清基础卵泡刺激素、黄体生成激素、雌二醇、人绒毛膜促性腺激素、日雌二醇水平、促性腺激素总量、促性腺激素天数及每组患者左右侧卵巢窦卵泡数、停促性腺激素日卵泡直径、获卵数、成熟卵子数.结果 两组血清基础黄体生成激素、雌二醇、人绒毛膜促性腺激素日雌二醇水平无明显差异,病例组基础卵泡刺激素水平、促性腺激素总量及促性腺激素天数均高于对照组(t值分别为1.21、1.65、2.62,均P<0.05);两组患者左右侧卵巢停促性腺激素日8~14mm、15~19mm卵泡数无明显差异,但右侧卵巢窦卵泡数、停促性腺激素日20mm以上卵泡数、获卵数、成熟卵子数均高于左侧(病例组:t值分别为1.70、2.81、2.64、1.23,对照组:t值分别为1.25、2.17、1.82、2.98,均P<0.05).结论 在体外受精-胚胎移植的控制性超排卵治疗周期中,右侧卵巢的反应性明显优于左侧. 相似文献

多囊卵巢综合征与神经内分泌功能异常 总被引:2,自引:0,他引:2
多囊卵巢综合征是育龄妇女最常见的妇科内分泌疾病之一,是引起无排卵性不孕的主要原因,其内分泌异常表现为黄体生成素(促性腺激素释放激素)脉冲波持续快速升高,黄体生成素/重组绒促卵泡激素的比例失调,重组绒促卵泡激素水平下降,卵泡形成受损及高雄激素产生.通过增强下丘脑对黄体酮的敏感性,可以抑制黄体生成素持续快速升高,体内过多的雄激素分泌却减弱了下丘脑对黄体酮的敏感性,进而削弱了黄体酮对促性腺激素释放激素的减速调节,加速黄体生成素(促性腺激素释放激素)脉冲波持续升高.促性腺素分泌的异常、高雄激素的产生和卵巢功能障碍都可能是多囊卵巢综合征内分泌功能异常的重要原因. 相似文献

目的:探讨国产促性腺激素释放激素(GnRH)——戈那瑞林代替人绒毛膜促性腺激素(hCG)诱发排卵的效果。方法;对采用克罗米芬(CC)及人绝经期促性腺激素(hMG)促排卵的104个周期,于卵泡成熟时,给予戈那瑞林,并与hCG诱发排卵的103个周期进行对照,观察排卵率、妊娠率及黄体功能。结果:用戈那瑞林诱发排卵,排卵率分别为90%(CC促卵泡发育)与91.66%(hMG促卵泡发育);妊娠率分别为18.51%(CC促卵泡发育)与19.44%(hMG促卵泡发育)。与 hCG组相比,差异无显著意义。黄体期 E_2、P及卵巢血供情况较 hCG组明显降低。结论:以戈那瑞林代替hCG具有相似的排卵率与妊娠率,但部分患者黄体功能不足,需早期进行黄体支持疗法。 相似文献

目的 探讨来曲唑与氯米芬联合尿促性腺激素促排卵治疗效果.方法 选择2008年1月1日~2009年6月30日于太和医院妇产科接受来曲唑与氯米芬联合促性腺激素促排卵治疗的不孕患者87例,共117个周期,分为两组,在月经周期第3天口服来曲唑5mg/d,氯米芬100mg/d,连续5天,并于月经周期第8天开始连续肌注尿促性腺激素,超声监测卵泡发育和内膜厚度.当优势卵泡≥20mm,或尿黄体生成激素阳性,肌肉注射人绒毛膜促性腺激素,之后指导同房或行宫腔人工受精;观察使用尿促性腺激素总量,成熟卵泡数,子宫内膜厚度,排卵率,妊娠率及并发症.结果 来曲唑组在使用尿促性腺激素总量、子宫内膜的厚度、排卵率及妊娠率与氯米芬组相似(P>0.05),成熟卵泡数低于氯米芬组(χ2=-2.704,P<0.05).结论 来曲唑与氯米芬联合尿促性腺激素促排卵比较,具有经济和安全的优点,两者总的临床效果相似,尚不能确定来曲唑较之氯米芬联合促性腺激素在不孕症促排卵治疗中具有优越性. 相似文献

卵泡发生及卵母细胞成熟是复杂的过程,需要促卵泡成熟激素(FSH)及黄体生成激素(LH)的共同作用。LH对提供雄激素底物以合成雌激素是必需的,而雌激素参与卵母细胞成熟,且对良好的受精及胚胎质量起一定作用。在多囊卵巢综合征(PCOS)患者及大多数接受辅助生殖技术的有排卵妇女中,用人绝经期促性腺激素(hMG)或纯FSH促排卵效果无区别。而对低促性腺激素性腺功能减退者用hMG治疗效果明显优于纯FSH。hMG不影响流产率。 相似文献

在一些特殊动物中,有关卵巢排出卵子数量的控制机制尚有争论。这些争论集中于其控制机制,近来研究强调卵泡血管的作用,即释放不等量的促性腺激素对不同大小卵泡的作用。为什么在同一的雌性中,在同样的激素环境中,一些卵泡生长发育直至排卵,而另一些卵泡闭锁。卵巢中的全部卵泡都有类似的促性腺激素环境,但当给予外源性促性腺激素时,将会刺激更多的卵泡排卵。这些有限量的内源性促性腺激素是如何由卵巢分配而分布的呢? 排卵前的卵泡与比它小的卵泡相比,其血管网较为丰富。这些丰富的血管网给予了显著卵泡浓缩的有效的促性腺激素,从而维持卵泡的生长。新近 相似文献

体外受精/胞浆内单精子注射(IVF/ICSI)助孕治疗中,促性腺激素释放激素拮抗剂(GnRHA)方案因促性腺激素(Gn)刺激时间短、总费用低、方案灵活、患者易接受等优点,广泛应用于临床。人绒毛膜促性腺激素(hCG)通常用来促使卵泡最后的成熟和排出(又称hCG扳机),与黄体生成激素(LH)促卵泡排出效果相似,但hCG的半衰期更长,延长的黄素化效应增加了患者发生卵巢过度刺激综合征(OHSS)的风险。而促性腺激素释放激素激动剂(GnRHa)在促进卵泡最终成熟和排卵的同时(又称GnRHa扳机),又能降低OHSS的发病率,已在临床应用。但目前研究结果表明,GnRHa扳机最终会导致黄体功能的缺陷并影响临床妊娠率,增加流产率。GnRHa扳机后采用何种黄体期支持才能消除新鲜胚胎移植时的顾虑仍无定论。综述拮抗剂方案中GnRHa扳机的优势和存在的争议。 相似文献

目的 寻找适合低促性腺激素闭经患者不孕症的最佳治疗方案.方法 对本院妇产科就诊的低促性腺激素性闭经患者15例进行38个促排卵周期的治疗,先采用雌孕激素替代治疗至少3个月,撤退性出血或周期第5天开始每日肌肉注射人绝经期促性腺激素(HMG) 150 ~450 IU,至少有1个卵泡直径≥18 mm后肌注人绒毛膜促性腺激素(HCG)8000 ~ 10000 IU诱导排卵、指导同房,基础体温(BBT)升高后给予黄体支持治疗.结果 总计进行了38个促排卵周期.诱导排卵周期中有效周期占78.9% (30/38),有效周期临床妊娠率为43.3% (13/30),双胎发生率为7.7%(1/13).结论 低促性腺激素性闭经不孕患者采用HMG 150 ~450 IU联合HCG 8000 ~ 10000 IU诱导排卵治疗,其优势卵泡增多,可提高临床妊娠率. 相似文献

目的探讨企业职工高尿酸血症(HUA)与血压、血脂、血糖的相关性,为企业进行健康管理提供依据。方法以中国石油长庆油田公司各下属企业为抽样单位,整群随机抽取2个单位,每个单位中所有的HUA者作为HUA组,共720人;同时在尿酸水平正常者中随机选取620人为正常组。通过Logistic回归分析HUA与年龄、性别、血压、血脂、血糖的关系。结果HUA合并高血压、高血脂、空腹m糖受损任意一项、两项、三项的比例均远高于正常组(OR值分别为:4.036,2.562,4.174)。多因素Logistic回归发现:男性、收缩压、总胆固醇、三酰甘油、低密度脂蛋白胆固醇是HUA的危险因素(OR值分别为7.736,2.309,1.721,2.761,1.411);高密度脂蛋白胆固醇为HUA的保护因素(OR值为0.211)。结论HUA存在性别差异,且与血压、血脂密切相关。企业对职工的健康管理应充分考虑多危险因素的综合作用,全面的进行健康教育及干预。 相似文献

Objective: Addressing health disparities requires well designed, culturally adapted research. However, recruiting/retaining minority participants has often been challenging. We present strategies used to successfully recruit and retain rural Hispanic women during a breastfeeding education intervention.Design: This study involved a two-group repeated measures quasi-experimental design with assessments at seven intervals between enrollment and 6 months postpartum. Participants (Hispanic women?≥?15 years old) were recruited through a regional hospital.Results: We successfully met our recruitment goals, most women contacted were enrolled (46 of 58), and 100% completed the study.Discussion: Research staff with ties within the community helped establish trust. Using bilingual study materials, simple language, and an interpreter addressed language/literacy concerns. Phone assessments facilitated participation as transportation was an issue. Accommodating requests to deliver or mail study materials and providing incentives were important. Extra effort was needed to maintain contact when phone service was disrupted or participants moved. Keys to success were persistence, flexibility, and alleviating barriers to participation. 相似文献

We used data from the Fragile Families and Child Wellbeing Study which includes a sample of adolescents of age 15 at the most recent wave (between 2014 and 2017) from mainly low-income urban families in the United States, to examine the association between neighborhood poverty entries and exits and adolescent depression and anxiety. In addition, we examined whether these associations differed by gender. Adolescents who consistently lived in disadvantaged neighborhoods had the highest level of depression and anxiety. Those who entered poor neighborhoods were more depressed than those who never lived in poor neighborhoods. Those who exited poor neighborhoods showed no significant difference in depression and anxiety compared to those never lived in poor neighborhoods. Furthermore, these associations applied to adolescent girls only and were not statistically significant for boys. The results suggest that neighborhood poverty has cumulative negative impacts on adolescent mental health and disproportionally affects adolescent girls. Reducing neighborhood poverty would substantially improve the health of adolescents, especially girls, which would reduce health disparities. 相似文献

Enabling positive change: Progress and setbacks in HIV and sexual and reproductive health and rights
Purnima Mane 《Global public health》2018,13(10):1341-1356
At a point in history when the future of sexual and reproductive health including HIV looks particularly uncertain, it is helpful to recognise that many of the challenges currently faced are neither new nor insurmountable. Reflecting on past achievements and lessons learned helps us to have confidence that positive change is feasible. This paper reflects on some of the changes observed in countries like India and Mozambique and identifies a range of factors which need to coalesce to enable these developments, along with specific contextual factors. It is the combination of these influences rather than any one of them alone that brought about the change in the three instances described – fostering a positive political response to HIV in its early years in India; bringing about policy reform on abortion in Mozambique; and increasing contraceptive prevalence and age at marriage in some districts in Bihar, India. Change is always fragile and susceptible to setbacks, but change-seekers can learn in the process and gain renewed hope that progress can and often does take place if they persevere. 相似文献
