Over the course of about six months my libido has taken a serious nose dive. Back in June I had my Testosterone checked and levels came back at 550. For a short period of time my libido returned and all seemed well. But recently it's completed or partially dropped off again. About two weeks ago, I had my levels tested again and Testosterone came back at 300. However I don't believe this was a reliable test, it was a walk in clinic, they tested me non-fasted and at about 12 noon after not having slept at all the the previous night. Finally after doing a lot more research I had a full battery of tests done after having fasted for 12 hours, test taken at 8 am. Results: Cholesterol 223 high Triglycerides 114 HDL 70 VLDL 23 LDL 130 Testosterone: 480 LH 5.8 FSH 3.9 Prolactin 16 High Estridiol 10.1 SHB 30.1 Hemoglobin A1c 5.7 High Just for reference I am 5'8" 136 lbs, I have moderate sleep apnea (20 AHI) I had Septoplasty surgery in November. Previous to the surgery/libido issues I was working out 4-5 days a week, felt great. It just feels like things hit a wall. I'd really appreciate any advice on this. Doctor mentioned retesting prolactin and possible getting an MRI for a benign tumor that could be producing the excess prolactin? Thank you for your time. I just really want to feel normal again.
