Hi dan, iamsu re you want to hear from men your age with prv. Although I am a woman, I find it interesting that you would have low testosterone. If I were you, I'd definitely ask my Hematologist about it. They may have other patients with the same problem. My own hematologist sometimes asks me about symptoms, wondering if I have the same ones as another patient. He could be very helpful with this problem.
My husband was diagnosed a couple of years ago with PV and began standard phlebotomy treatment to manage it, sending his iron stores plummeting. He has experienced great fatigue and symptoms like depression. Recently, on a trip to see our family doctrine, it was suggested that he might be experiencing those symptoms because of low testosterone levels; he is now waiting for bloodwork results to be returned.
I was surprised to see that for individuals boosting their testosterone, it is common practice to monitor them for development of PV. This leads me to wonder whether in individuals who already have PV, the low testosterone isn't a mechanism triggered by the body in an attempt to modulate the PV. Have you ever discussed this possibility with your hematologist? My husband is seeing his next week; I think it would be a good question to ask. I'll get back to you with a response.
