目的 了解血清睾酮(T)/雌二醇(E2)比值变化对精子缺陷程度及男性生育能力的影响.方法对90例已婚育龄男性进行血清T、E2、卵泡刺激素(FSH)、黄体生成素(LH)、催乳素和精液参数、精子形态测定,计算血清T/E2和精子多重缺陷指数.根据血清T/E2分为≤10(1组)、>10(2组)及>20(3组)分别比较.结果 1、2、3组精子密度和精子活动力分别为(66.8±39.6)×106、(57.6±33.9)×106、(77.4±26.0)×106/ml和(46.6±16.4)%、(44.9±16.0)%、(53.9±14.4)%,3组间差异无统计学意义(P均>0.05).1组头部缺陷精子为(81.4±9.4)%,明显高于3组的(74.0±10.7)%(t=2.482,P=0.016);1、2组颈部缺陷精子为(16.9±8.6)%和(12.7±9.8)%,均明显高于3组的(7.1±3.9)%(t=4.113、2.050,P=0.000、0.046);1、2、3组尾部缺陷精子分别为(22.6±14.6)%、(14.6±9.0)%和(6.5±5.7)%,组间差异有统计学意义(t=2.722、3.996、3.110,P=0.008、0.000、0.003).2组精子畸形指数(SDI)(1.4±0.3)明显高于1组(1.3±0.2,t=2.293,P=0.025);2、3组畸形精子指数(TZI)分别为1.6±0.3和1.6±0.2,明显高于1组的1.4±0.2(t=2.285、2.727,P=0.025、0.009).1、2、3组中配偶有生育或妊娠经历者分别为13、16、6例,组间差异无统计学意义(x2=3.285、0.854、0.199,P=0.070、0.355、0.655),但2、3组相对危险度分别为1组的2.4倍和1.8倍.1、2、3组中特发性不育病例分别为25、15、7例,组间差异均无统计学意义(x2=0.735、0.200、0.038,P=0.391、0.655、0.845),1组相对危险度分别为2、3组的1.5倍和1.3倍.相关性分析结果发现,血清T/E2与头、颈和尾部缺陷精子比率呈显著负相关(r=-0.209、-0.316、-0.335,P=0.048、0.002、0.001).结论血清T/E2与精子头、颈及尾部缺陷呈显著负相关,其下降与男性生育概率降低有关,但并不影响精子密度及活动力,表明男性体内维持较高比例的T/E2水平对于精子发生过程中的精子形成阶段及受精能力有重要意义.Abstract: Objective To study the effect of the serum testosterone/estradiol ratio (T/E2) alteration on sperm defect and fertility. Methods The testosterone, estradiol, FSH, LH, PRL,sperm parameters and sperm morphology of 90 men were analyzed and the T/E2 and multiple anomalies index (MAI) were calculated. The patients were divided into 3 groups; T/E2≤10 (Ⅰ), T/E2>10 (Ⅱ), and T/E2>20 (Ⅲ). Results The sperm concentration and motility among the 3 groups were not significantly different (P>0. 05). The percentages of the sperm whose head, neck and tail were abnormal declined gradually with the increase of the T/E2 in serum. The percentage of sperm head defeet of group Ⅰ was significantly higher than that of group Ⅲ (t=2. 482, P=0. 016) and that of sperm neck defect of groups Ⅰ and Ⅱ were significantly higher than that of group Ⅲ (t=4.113, 2. 050, P=0.000, 0. 046, respectively). The percentage of sperm tail defect among 3 groups was significantly different (t=2. 722, 3. 996, 3. 110, P=0. 008, 0. 000, 0. 003, respectively). The SDI of group Ⅱ was significantly higher than that of group Ⅰ (t= -2. 293, P= 0. 025). But the TZI increased gradually with the increase of the serum T/E2 and the TZI of groups Ⅱ and Ⅲ were significantly higher than that of group Ⅰ (t=2. 285, 2. 727, P=0. 025, 0. 009, respectively). The percentage of the men in group Ⅰ whose partners became pregnant was 29. 5% and those of groups Ⅱ and Ⅲ were 50% and 42.9%, respectively. Although the percentage among three groups was not different statistically (x2 = 3. 285, 0. 854, 0. 199, P= 0. 070, 0. 355, 0. 655, respectively), the relative risks of groups Ⅱ and Ⅲ were 2.4 and 1.8 times of that of group Ⅰ. There were 25, 15, 7 cases of idiopathic infertility among the 3 groups, respectively. The relative risk of I group was 1.5 and 1.3 times of that of Ⅱ and Ⅲ groups. The correlation analysis showed that the T/E2 in serum had significantly negative correlation with the percent of the sperm head or neck or tail defects (r= -0. 209, -0. 316 and -0. 335,respectively and P= 0. 048, 0. 002 and 0. 001, respectively). Conclusions The decrease of T/E2 in serum was correlative with the decrease of fertility probability, but it did not alter the sperm density and the sperm motility. It showed that the level of the T/E2 in serum was important for spermatogenesis and sperm fertilizing capability. 相似文献

目的:了解取出宫内节育器(IUD)妇女的心理状态,探讨规范计划生育服务对妇女心理状态的影响。方法:选取我国IUD使用有代表性的6个省的医疗服务机构作为研究现场,以抽签的方法随机决定干预组和对照组。干预组按照标准操作程序进行IUD取出手术,对照组则按照各协作中心日常的操作技术进行。对2008~2009年到本研究的各协作中心进行取出IUD手术并自愿参加本项研究的970例健康研究对象在手术前和手术后1个月随访时进行症状自评量表(SCL-90)的心理测评。结果:研究对象术前各因子评分均高于术后(P<0.05);干预组量表中各因子评分均低于对照组(P<0.05)。结论:规范取出IUD操作对提高取器妇女的心理健康状态有一定的作用。 相似文献

人工流产妇女避孕方法失败原因调查分析 总被引:7,自引:2,他引:5
目的:研究开展知情选择工作后人工流产的发生情况。方法:采用问卷调查,对10个样本点计划生育服务站门诊因使用宫内节育器(IUD)、避孕套、口服避孕药发生意外妊娠行人工流产的已婚育龄妇女进行术前面对面的代填式问卷调查。结果:本次IUD避孕失败的主要原因为IUD下移及脱落(占75.5%),IUD放置机构主要集中在乡镇、街道卫生院。使用避孕套及口服避孕药失败的主要原因均为未规范使用。结论:加大宣传力度,普及紧急避孕知识,重视日常咨询和随访,提高基层技术服务能力,是提高避孕有效率,避免非意愿妊娠,促进生殖健康的有效途径。 相似文献

人工流产作为避孕失败的补救措施,早已被广泛接受.但是随着人们生活水平的提高以及医疗条件的改善,如何减少孕妇的术中痛苦显得极为重要.为了摸索最佳方法,2003年1月至2003年12月,笔者将笑气吸入联合米索前列醇的术中镇痛效果,与目前常用的异丙酚静脉注射麻醉进行比较与总结. 相似文献
