I Am On Avodart For Enlarged Prostate And 50 Mg

I am on avodart for enlarged prostate and 50 mg atenanol for high blood pressure. I am 70 with normal sex life, but have developed retrograde ejaculation in the last year. My 'T' is still about 500 or do. Taking a number of 'natural' vitamins too, as recommended by a Nutricionist Dr. mostly for some inflammation, help heart, and lose weight. Strong, exercise a lot and healthy. Ideas? Thank you.
