胚胎发生早期的生理和病理、子宫内移植体外受精卵可能性的研究尚处于积累资料阶段。虽然在女性和男性配子发生的形态学及生理学领域的研究取得了很大成就,由于取材困难,卵母细胞成熟的许多方面尚未研究。人的植入前和植入后早期发育的研究也有一定困难。近年来人卵母细胞体外培养和受精技术的研究应用是有前途的。这项技术可用以治疗某种类型不育。应用体外受精和人胚移植的指征是某种类型男性不育(精子过少)和女性不育(不能由外科矫治的输卵管梗阻或先天性输卵管梗阻,某种类型子宫内膜异位症)。妇女的卵巢和子宫功能正 Early embryogenesis physiology and pathology, the possibility of uterine transplantation in vitro fertilized eggs is still in the accumulation of data stage. Although great achievements have been made in the field of morphology and physiology of gametes in female and male gametes, many aspects of oocyte maturation have not been studied due to difficulties in obtaining the materials. Studies of human pre-implantation and early post-implantation development also have some difficulties. In recent years, human oocyte in vitro culture and fertilization technology research and application is promising. This technique can be used to treat some type of infertility. Indications for IVF and human embryo transfer are some types of male infertility (oligospermia) and female infertility (tubal obstruction that can not be surgically treated or congenital fallopian tube obstruction, some type of endometriosis) . Women’s ovarian and uterine functions are positive
