maybe karin did some organ transplant or blood trnsfusion to save sarada live when she was a child (uknown to sasuke and sakura). and i remember in suigetsu panel in chapter 700+7 suigetsu suspect somehow or someway get whatever it is from sasuke without sasuke noticing it or simply sakura can't get pregnant
