一些同源結構

男女性系統的一些同源結構

在男嬰出生之前,“雄性”激素-睾丸激素將其原初未分化的胚胎轉化,引導發育成具有男性性器官的男胎。而在女胎,在這個發育期缺乏睾丸激素,使得原始胚胎“自動”長成具有女性性器官的女胎。但是,既然男女的性器官由相同的胚胎細胞團衍生而來,它們相互對應,或者用科學語言來說,它們是“同源的”。

Some Homologous Structures

Some Homologous Structures in the Female and Male Sexual Systems

Before a baby boy is born, the "male" hormone testosterone transforms his originally undifferentiated embryo, leading to the development of a male body with male sex organs. In case of a baby girl, the absence of testosterone at this stage lets the embryo grow "automatically" into a female body with female sex organs. However, since both male and female sex organs derive from the same embryonic cell mass, they still correspond to each other or, in scientific language, are "homologous."
