1.3.5 辅助生育和弱精症治疗

不孕不育是年轻夫妇的常见疾病之一,目前其发病率已高达10%以上。解决途径除了一般性内分泌调理外,辅助生育(俗称试管婴儿)是最有效的治疗方法,但其费用较高而成功率较低(国际水平为30%左右),难达理想水准。Paulus等2002年首先报道针刺治疗可以提高辅助生育成功率,但各家报道效果不稳定,可能与针刺手法参差不一且难以定量有关。我们在山东中医药大学生殖医学中心用韩氏治疗仪(HANS)行经皮穴位电刺激方法,试图提高辅助生育成功率。我们在选定的8个穴位(腹部4个,下肢4个)进行治疗,在受精卵植入前24h及植入后30min各进行一次TEAS,对照组成功率为29.3%,TEAS组为50%,差别非常显著(P<0.01)[24]。在此基础上,在北医三院、湘雅生殖中心等全国著名生殖中心的参与下,我们进行了多中心临床试验,不仅确认了上述初步观察结果,而且优选了最佳电刺激参数和最佳穴位,确认了孕妇最佳治疗年龄段,阐明了主要的作用原理,使韩氏仪辅助生育的治疗方法提高到一个全新的国际科学水平。

不孕不育的原因可能来自女方,但也可能来自男方,如属于后者,对女方实施经皮穴位电刺激治疗显然不能奏效。男方病因可能为少精症(精子数目过少)或弱精症(精子游动能力过弱),为此对男方进行韩氏仪治疗,发现经过1个月治疗,其精子游动能力大幅提高,但精子数量增加不明显;经过2~3个月治疗,精子数量也有明显的升高趋势。该项研究正在进行中。
