【摘要】 通过观察101例正常发育的男性胎儿(胎龄12～33周)的睾丸及其相关结构,得到以下结果:1.提供了胎儿睾丸、附睾和引带的生长发育资料。2.发现所谓的阴囊韧带实际上并不存在,引带是一个间充质组织的柱锥体,客观上没有一个牵引睾丸下降的解剖结构。3.中国人胎儿睾丸下降的时间发生在孕21～25周之间,26周之后已全部下降完毕,比传统认为的第7～8个月有明显的提前。4.证实了睾丸一旦下降开始,很快通过腹股沟管,一般左侧比右侧有先下降的倾向。鉴于以上发现,作者认为有必要对传统概念进行修正。更多还原

【Abstract】 The testis and its relative structures of 101 normal male fetuses (fetal-age 12-33 weeks) have been studied in this paper. The results were as follows: 1. The data of fetal growth of testis, epididymis and gubernaculum were given. 2. It has been found that there is no scrotum ligament existed. The gubernaculum is a mesenchyme tissue and is cylindrical pyramid in shape. Objectively, we cannot find any anatomical structure acted as a tractor in testis descending. 3. It has been found that the testis descends in chinese fetus between the 21th and the 25th week of fetal-age. It was completed in all of them after the 26th week. The time is more advanced than that of the traditional conception which referred to be between 7 th and 8 th month. 4. It has been confirmed that once the descent started, the testis run through inguinal canal rapidly. Generally, it seems that the testicular descent in left side is earlier than that in the right. From the above findings, the author suggests that it be necessary to correct the traditional conception in the Chinese anatomy book.更多还原
