If I decide my PCP doesn't know what he's doing when my results come back, which type of specialist should I go to see? Some on the forum are suggesting a urologist if testicular production of testosterone is the problem and others suggest an endocrinologist if the problem is related to the pituitary function. Seems my current doctor isn't differentiating between which is causing the low t since he has only drawn total t and now testing my free t for his diagnosis. I'm a little confused. Don't I really need LH and FSH tests and later on estradiol to really zone-in on what's really going on here? Thank you.
