英文医学科普|体外受精

Intracytoplasmic sperm injection, or ICSI, is a form of in vitro fertilization in which fertilization occurs outside of the body. First, egg cells are harvested and transferred to a special media in a laboratory dish. Within a few hours, a single sperm is injected through a fine needle into the center of an egg cell to aid in the process of fertilization. If successful, the cell will divide and form the beginning stages of an embryo. If necessary, the DNA of a single cell from an embryo may be checked to ensure that various genetic disorders are not present. Typically, several egg cells are harvested and fertilized at the same time then inserted back into the uterus to increase the chances that one will implant and develop into a successful pregnancy.

卵胞浆内单精子注射或ICSI是体外受精的一种形式,其中受精发生在身体外部。首先,收获卵细胞并转移到实验室培养皿中的特殊培养基中。在几个小时内,通过细针将单个精子注射到卵细胞的中心以帮助受精过程。如果成功,细胞将分裂并形成胚胎的开始阶段。如有必要,可以检查来自胚胎的单个细胞的DNA以确保不存在各种遗传疾病。通常,收获几个卵细胞并同时受精,然后插入子宫中以增加植入和发育成功的机会。
