Was the dogma of the Immaculate Conception formulated in response to someone challenging Mary's ability to bear a perfect Son?

I read that dogma is the church's way of explaining supernatural events in scripture Since I have been doing research on the question of how a perfect Jesus could be born of a descendant of Adam, it occurred to me that the Immaculate Conception dogma may have come about in this way. Is it recorded anywhere that a challenge was made regarding Mary being imperfect, thus not able to bring forth the Savior, and the early fathers responding to this with the dogma that explains the supernatural way this could be accomplished?
