Could drinking too much caffeine cause prostate problems?

Possibly: Caffeine can be an irritant to both the bladder and the prostate. Fortunately, it does not affect most people.

Yes: Some doctors believe that caffeine itself is harmful to the urinary tract, and is an irritant. It is clear that caffeine is a diuretic, a drug which increases urinary flow, and in men who already have an enlarged prostate with age, or an inflamed prostate with prostatitis, the more you have to urinate, and the more urine there is, the more problems you have. Alcohol and caffeine should be avoided.
