Can therapy diminish an author's urge to write?

What prompted me to this question was thinking about authors whose books are fiction and auto-psychoanalytical. The themes are always personal obsessions they have which urge them to write about them. The work is never auto-biographical. They write esoteric fiction that reads as very real. They write compulsively, locked in their private space for hours. I wonder if these authors went through therapy and talked about their obsessions whether they might lose the urge to write about them. I'm thinking that if therapy won't diminish an author's urge to write, how it might affect his choice of themes and literary style going forward.
