摘要
性别控制是人类很早就关心的研究领域,许多重要的经济性状与性别有直接的关系。控制受精环境即可控制性别,这种方法不需昂贵的仪器设备或者药品,易实践,可普遍应用,其经济效益和社会效益难以估量。文章综述了受精环境对哺乳动物性别形成影响的研究进展。这些环境因素包括母体生殖道中精氨酸含量、胚胎发育过程中子宫内葡萄糖浓度、输精时卵母细胞成熟程度以及哺乳动物受孕时生殖激素的水平等方面,为进一步开展性别控制研究积累一定的资料。
Selection of sex at or before conception is perhaps the most desired biotechnology of all time because many economic traits are related with sex. Sex selection by manipulating the conditions of sperm-oocytes fertilization would be one of the most practicable and widely used methods. This review summarized the progress in the effects of fertilization conditions on mammalian sex. Four main factors which possibly affected sex were described such as arginine concentration in female animal vagina, glucose in the uterus, maturational status of the oocyte at the time they encounter sperm as well as the hormone levels of both parents at the time of conception.
