石女和双无是一回事吗?Is Shinu the same as Shuangwu?

陈凤林教授指出：石女又叫先天无子宫无阴道，由于缺少阴道粘膜和子宫内膜，被称为“双无”。系因胚胎时期双侧副中肾管未发育，停止在原始状态。卵巢及输卵管一般发育正常，部分人附件未下降入盆腔。

Professor Chen Fenglin pointed out: Shinu is also called congenital absence of uterus without vagina. Because of the lack of vaginal mucosa and endometrium, it is called "double absence". Because of the undeveloped bilateral accessory mesonephric ducts during embryonic period, it stopped in the primitive state. Ovarians and fallopian tubes generally develop normally, and some people's appendages do not fall into the pelvic cavity.
