保留性交过程对阴道内授精助孕效果的影响

How keeping the process of intercourse assists intravaginal insemination and fertilization

目的:对不孕不育因素为精液液化延迟且经一定时间中西药物治疗后液化状态无改善的患者,验证保留性交过程条件下机械性抽打液化延迟精液并行阴道内授精助孕的临床效果。方法:具有精液液化延迟不育因素的80对夫妇被区分为保留性交过程组和非保留性交过程组,在排卵期分别由患者或由医务人员以同样方法实施机械性抽打液化延迟精液并行阴道内授精,观察两组2个阴道内授精周期的妊娠率。结果:保留性交过程组和非保留性交过程组第1周期阴道内授精周期的妊娠率分别为30.0%和17.5%,第2周期的妊娠率分别为25.0%和9.1%,差异具有显著性(P<0.05)。2个授精周期分别获得累计妊娠率47.5%和25.0%。结论:两组以简单的机械性抽打精液和阴道内授精方法,初步显示了本机械性抽打精液方法的临床价值,保留性交过程组和非保留性交过程组在妊娠率上存在显著差异,提示性生活过程介入对阴道内授精助孕效果存在一定影响。

Objectives：By studying the cases of infertile patients who confirmed delayed semen liquefaction and reported no positive response to integrated traditional Chinese and western medicine treatment,the research group tried to investigate how the process of intercourse assists intravaginal insemination and fertilization in clinic application.Methods：80 infertile couples with confirmed delayed semen liquefaction were randomly divided into 2 groups：family group and hospital group.In ovulatory phase,the semen of patients in both groups were repeatedly whipped in the same way by doctors or patients themselves and intravaginal inseminations were applied.The pregnancy rates in both groups were recorded for two fertilization cycle.Results：Pregnancy rate of family group in the first fertilization cycle was 30.0% while the rate of hospital group was 17.5%.The rates in second cycle were 25.0% and 9.1%.The statistical analysis suggests significant difference（P＆lt;0.05）.These two groups with the treatment of simple repeated whipping and intravaginal insemination in the two fertilization cycles respectively accumulate a pregnancy rate of 47.5% and 25.0%.Conclusion：Preliminary study demonstrated the clinical value of this method.The family group and the hospital group had significant difference in pregnancy rate,suggesting that the factor of sexual behavior was involved in the outcome of intravaginal insemination.
