雄激素在人类胚胎期性分化中起着十分重要的作用。虽然染色体的组成在受精时已决定了胎儿的性别 ,但性的分化却是在胚胎第 7、8周之后 ,随着生殖腺及生殖导管的分化而逐渐展开的。我们知道 ,胚胎期生殖导管有一对中肾导管与中肾旁管 ,目前研究认为不论性染色体是ＸＸ(女性 )或? Androgen plays a very important role in human embryonic differentiation. Although the composition of chromosomes determines the sex of the fetus at the time of fertilization, sexual differentiation gradually unfolds with the differentiation of the gonads and reproductive ducts after the 7th and 8th week of the embryo. We know that there is a pair of embryonic reproductive catheter in the renal and para-renal canal, the current study that regardless of sex chromosomes XX (female) or?
