Is it true that testosterone therapy increases red blood cell count in men?

Yes. Multiple sources, including a clinical guideline and peer-reviewed studies, state that testosterone administration increases red blood cell production, hemoglobin, and hematocrit in men, with erythrocytosis a recognized adverse effect of therapy.
