Romeo and Juliet "take their life" from their parents' "fatal loins" in the sense that their parents gave them each life. But these words also hint at the play's conclusion, in which Romeo and Juliet will die by suicide, due to circumstances brought about by the "fatal" (as well as fateful — and perhaps fated) feud between their two families. This wordplay represents yet another double meaning in the Prologue, whose sonnet form encourages dense wordplay.
