So I’ll start by posting my latest levels with reference ranges from where I tested:
Total testosterone: 403 ng/dl (reference range 173-749 but this range seems far too low)
Bioavailable Testosterone: 227 ng/dl (reference range 80-605 again, the lower end seems a bit low, I saw a range of 131-682 in an article here at T-Nation)
SHBG: 25 nmol/L (reference range 15-95)
Sensitive E2: 22 pg/ml (reference range 7-40)
LH: 4.4 IU/L (reference range 1.24-7.8)
FSH: 3.2 IU/L (reference range 1.5-12)
TSH: 1.76 (reference range 0.4-4.0)
Free T4: 11 nmol/L (reference range 7.6-16)
Free T3: 5.4 nmol/L (reference range 3.6-6.3)
Body Temperature: 97.7 degrees in morning and 98 in evening on average.
Hemoglobin: 157 g/L (reference range 134-170)
Glucose: 5 nmol/L (reference range 4.0-6.0)
PSA: 0.35 ug/L (reference range <2.0)
Prolactin: 193 mIE/L (reference range 64-403)
DHEAS: 9.2 micromol/L (reference range 5.7-13)
Weight: 150 lbs
Body fat percentage: 14% or so (estimated)
So my levels are overall fine but my FSH, LH, Bioactive and total testosterone are at least on the lower end of the ranges. Anyway, the reason I make this post is that I have gradually been losing my libido in the last couple of years. Two years ago, it started fluctuating between high and low and since a few months back (April or so) it has been low constantly. I get no morning wood, but I can still get erections when I masturbate, but there is barely any pleasure on account of the nearly dead libido. I should mention that a year ago or so my total testosterone levels were 490 and my SHBG was 14 and my libido was better then (fluctuating between high and low at least, not constantly low). Funnily enough my TSH was higher at 2.66 but my T3 was higher too (6.5 nmol/L) and T4 was about the same.
So basically, I am wondering, is it plausible that my dead libido is caused by low testosterone levels? Or are my levels not low enough to cause this? And if so, should I try to naturally raise my levels or will I need TRT? I have considered that this could be a thyroid problem as I did have a high TSH of 2.66 before. But considering that it was at 1.76 now, my T3 levels are fine, my temperature is at least acceptable and the fact that I have consistently gotten enough Iodine in my diet in the past several years, I doubt there is much I can do there, at least naturally. I have also considered adrenal fatigue (and I will order a 24 h salivary cortisol test soon) as I used to have a lot of stress a year or so ago. But my stress levels have been as low and stable as ever in the last year so it doesn’t make sense that that would be the cause of my suddenly dead libido in the last few months.
I also took Accutane (which can supposedly cause permanent sexual dysfunction) when I was 16 but that was 8 years ago and my libido was consistently high until I was about 21-22 so I certainly doubt that started causing effects 6 years after stopping usage. I also took Ashwagandha for a year or so but stopped in May. But I doubt that can have such an effect either.
I should also mention that I have not noticed any fat gain or muscle loss, I have maintained just fine in the gym for the last couple of years. I also have some mild brain fog and fatigue, but nothing that bothers me as much as the libido thing. I also struggle to fall asleep sometimes and often wake up in the middle of the night. I have a strict sleep routine though so I make sure to get at least 7h of sleep consistently. I also eat a healthy diet with a good amount of protein and healthy fats.
Anyway,I really want to find a reason for my dead libido, so I am kind of hoping that it is the testosterone thing. Do you think that is plausible, and if so, should I try to get on TRT or would I be able to raise it naturally with supplements to decent levels?
