I am a 45yo male. I have low T (191) but has been as low as 161. I have had pit. MRI (-), LH, FSH, estradiol, prolactin, TSH, everything checked and everything comeback normal. No MD ordered a US but I wanted one so got it done everything normal except minimal hydrocele. Do You have any ideas as what may be the prob. I am healthy 6 5 250, work out 4-5 times a week although my workouts are what Im used to. Had this prob since 2012.
