体外受精一胚胎移植(IVF-ET)是目前辅助生殖领域治疗不育不孕症的常用手段,也是近年医学研究关注的热点。但长期以来,这种技术成功率始终较低,其原因除了种植率较低以外,还存在妊娠后流产以及早产率高等。而导致这些原因的因素有很多方面,其中微生物学的感染可能是其中之一。微生物是存在于自然界的一大群形体微小、结构简单、肉眼不能直接看到,必须借助光学显微镜或电子显微镜放大数百至数万倍才能看到的微小生物。微生物包括病毒、细菌、螺旋体、支原体、衣原体、放线菌、真菌
In vitro fertilization and embryo transfer (IVF-ET) is currently used in the field of assisted reproductive infertility infertility commonly used means, but also medical research in recent years, the focus of attention. However, for a long time, the success rate of this technique has always been lower because of the low rate of implantation, abortion after pregnancy and higher premature birth rate. There are many reasons for these reasons, of which microbiological infection may be one of them. Microorganisms are tiny organisms that exist in nature and are small in size, simple in structure and can not be directly seen by the naked eye. They must be magnified by optical microscope or electron microscope hundreds to tens of thousands of times. Microorganisms include viruses, bacteria, spirochetes, mycoplasmas, chlamydia, actinomycetes, fungi
