I am 61 years old and I have had 6 episodes of blood in my semen over the past 2 years. I have had many prostate exams including ultrasound and the scope and have ruled out cancer, nor do I have an enlarged prostate. My PSA is 1.2. During these 2 years I have also had two kidney stone attacks that required liprotripsy. Over the past 10 years I have had 4 more kidney stone attacks that required liprotripsy. I finished my last antibiotic treatment about 2 months ago and now the blood is back. The other symptoms I have is burning when I urinate and frequent need to urinate. The burning sensation is new and has only occured the during the last episode and this one. I am also taking androgel because my testestrone levels go below 200 when I don't use it.
