针灸可以改善精子质量


  July 25, 2005 - 根据七月份繁殖与不孕期刊(Fertility and Sterility),一项先期性的研究结果显示,原发性男性不孕症可以藉由针灸改善精子质量。
  
  中国上海中医大学的Jian Pei博士表示,一些非对照式的临床试验报告指出,不孕症的男性使用针灸后,在精子的浓度及活动力方面获得改善,睾酮素有了增加,激卵激素(LH)亦获得一些改善;这些研究同时显示,正常型态的精子有了增加,异常型态的精子比例获致明显的降低。
  
  40位原发性不孕症的男性参与试验,症状为精虫不足,精虫活动力不足,或精虫型态异常者;其中28位(70%)接受两周一次的针灸治疗,持续5周,试验者的精液样本以随机的方式和12位未接受治疗的对照样本作比较;以传导式电子显微镜作定量分析,此分析结果视为试验的主要效果。
  
  针灸之后,改善的项目包含精虫的数量、顶体型态与位置、细胞核形状、轴丝型态与形状,以及精虫的附属纤维等,总射精中并未发现超显微结构的异常;细胞计画性死亡、不成熟,及细胞凋亡等特定的病原,在治疗前后并无明显改变,试验组与对照组间亦无明显差异。
  
  Pei指出,原发性男性不孕症可以藉由针灸的治疗而获益;在针灸之后,改善的项目,在精虫的显微结构上尤其明显;但是,本试验并未指出对针灸治疗不敏感的特定精子病原。
  
  本试验由中国的国家机构赞助,含The National Natural Science Foundation of China and the Key Projects Foundation, State Administration of Traditional Chinese Medicine。

Acupuncture May Improve Sperm<

July 25, 2005 — Acupuncture may improve sperm quality in idiopathic male infertility, according to the results of a prospective study reported in the July issue of Fertility and Sterility.

"Reports from uncontrolled trials using acupuncture on infertile men have shown a positive effect on sperm concentration and motility, an increase in testosterone, and some improvement in luteinizing hormone (LH) level," write Jian Pei, PhD, from Shanghai University of Traditional Chinese Medicine in the People's Republic of China, and colleagues. "These studies have also shown an increase of normally shaped sperm and a significant decrease in the percentage of morphologically abnormal sperm."

Of 40 men with idiopathic oligospermia, asthenospermia, or teratozoospermia, 28 (70%) received acupuncture twice weekly for five weeks, and their semen samples were randomized with semen samples from the 12 men in the untreated control group. The primary outcome was quantitative analysis by transmission electron microscopy.

After acupuncture, there was a statistically significant increase in the percentage and number of sperm and improvement in acrosome position and shape, nuclear shape, axonemal pattern and shape, and accessory fibers of sperm organelles, without ultrastructural defects in the total ejaculates. Specific sperm pathologies in the form of apoptosis, immaturity, and necrosis did not change significantly between the control and treatment groups before and after treatment.

"The treatment of idiopathic male infertility could benefit from employing acupuncture," the authors write. "A general improvement of sperm quality, specifically in the ultrastructural integrity of spermatozoa, was seen after acupuncture, although we did not identify specific sperm pathologies that could be particularly sensitive to this therapy."

The National Natural Science Foundation of China and the Key Projects Foundation, State Administration of Traditional Chinese Medicine, People's Republic of China, supported this study. The authors report no conflicts of interest.
