争论不是在于技术差多远，你真能跑题。而是只要能怀孕就算女人这个问题，出现这种情况，该依靠什么来鉴定男女性别？是基因还是子宫？又换句话，一个有发育不良的男孩外生殖器，其实染色体是女性的，那么他是不是男性？

保温箱和子宫是一个概念吗？一个可以让受精卵成长成人，另一个只能让早产儿不死。你这才叫跑题。
另外xx男的确是男性。
Some males will have a 46,XX karyotype if there has been exchange between the X and Y chromosomes in paternal meiosis. The father, who now has SRY on the X chromosome, transmits this to his offspring, who also get an X from their mother. Since SRY is present, the undifferentiated gonad will become a testis and secrete AMH and testosterone.
