近年来国内外对生殖生物学和生殖生理学进行了很多研究,其中包括卵巢及女性生殖器官的发育和形成。现将有关卵巢的发育和排卵的问题简述于后。一、卵巢组织的发生在胚胎第3周,原始生殖细胞(primitive germcell)由卵黄囊的内胚层,近尿囊憩室部的表皮细胞发生。原始生殖细胞以变形虫样运动向泌尿生殖嵴(urogenital ridge)移动。这时的原始生殖细胞尚未分化男女性别。在胚胎第6周时,原始生殖
In recent years, many researches have been done on reproductive biology and reproductive physiology at home and abroad, including the development and formation of ovary and female reproductive organs. Now ovarian development and ovulation problems outlined below. First, the occurrence of ovarian tissue In the first 3 weeks of embryo, primordial germ cells (primitive germcell) from the yolk sac endoderm, near the allantois diverticulitis epidermal cells occur. The primordial germ cells move toward the urogenital ridge with amoeboid motility. At this time the original germ cells have not yet differentiated between men and women. At the 6th week of embryo, primitive reproduction
