用脚指头想也知道，皇后自己生不出男孩，怎么容许别的妃子生儿子来动摇他的地位呢？母凭子贵，从古时候到现在都没变，当女人好像就是要生个儿子才能巩固自己在婚姻中的地位。

It doesn't take much to work it out, the Empress hasn't been able to give birth to a son, why would she let the son of a concubine threaten her position? Mothers are only important for the sons they give you, that has remained the same from ancient times until the modern day, having a son consolidates a woman's status in her marriage.
