If one went to the bathroom after hearing Borchu but before he started birchas krias shma, is he allowed to make an Asher Yatzar? I ask because I know that one is not allowed to talk after borchu because it is the beginning of birchas krias shma. Does the same apply to Asher Yatzar?
He should wait to say Asher Yatzar until after Shemona Esrei. There is no need to say Asher Yatzar immediately after exiting the bathroom, therefore it should wait.
