I'm healthy 67 yr old with mild ED and BPH. I've taken terazosin for BPH urine flow for a few years..Viagra for about a year and it works really well..I started finasteride after my Urologist said it's a "good combination". My problem is that to reach orgasm takes forever (or not at all) and have very little semen volume. He stopped the finasteride and switched to tamsulosin from terazosin. He says my prostate is only slightly enlarged after 6 mo. of treatment..But I'm worried about impotence resulting from BPH meds. Will the ejaculatory dysfunction and semen volume return to normal? Does the prostate enlarge again? Thanks so much!
