For the last 4 years my Prolactin has been slightly elevated (above the high range) on every test. I had a Macroprolactin test and confirmed it is high prolactin. My Doc has ordered a MRI. I also should mention that I have low Estrogen, I have never taken an AI, been on TRT for 12 years. I take a small dose 60mg per week. I also wonder if my exercise routine for the last 20 years has started contributing to my high levels. I run 5 miles a day at least and workout with weights 5 days a week too. I am 65 years old.
