生殖是人类和生物界绵延其种族生命的共同现象,而有性生殖则是进化中的最高形式。但是人类自然的有性生殖有时发生缺陷,或者不符合人类的要求,所以改变或改造自然生殖过程的研究就成为敢于开拓新领域的科学工作者全力以赴的主要目标。首先是人工授精的研究,接着是体外受精—胚胎移植(IVF—ET),即俗称“试管婴儿”。本文简述IVF—ET各个环节的改进,随后简单介绍由此而发展的各种生殖工程新技术:胚胎冷冻贮存、配子输卵管内移植、合子或胚胎输卵管移植、胚胎赠送、代理
Reproduction is a common phenomenon in human and biological circles that stretches its ethnic life, while sexual reproduction is the highest form of evolution. However, the natural sexual reproduction of mankind sometimes flaws or does not meet the requirements of mankind. Therefore, the study of changing or reforming the natural reproductive process has become the main goal of scientific workers who dare to open up new fields. The first is the study of artificial insemination, followed by IVF-ET, commonly known as “IVF.” This article outlines the improvements in all aspects of IVF-ET, followed by a brief introduction of the development of a variety of new technologies of reproductive engineering: embryo cryopreservation, gamete tubal transplantation, zygotes or embryonic fallopian tube transplantation, embryo donation, agency
