I'm a 38-yr-old otherwise healthy male and my TSH came back as 3.36 and my T4 as 11. According to Thyroid UK and other mainstream thyroid websites, this is 'subclinical' ie on its way to being a problem - tho' I haven't got the exact range done by the lab in question. I practically had to twist my GP's arm to get T3 bloods done which I'm awaiting. Over the last couple of years I've noticed a definite decline in my energy levels and libido (such that I rely on moderate ED drug usage), which is upsetting. My muscles also mildly ache when I wake up tho' I do exercise. On the other hand, tho' i do put on weight more easily, I've not ballooned nor have I noticed my hair or nails becoming more brittle. I've always had probs with depression, so it's hard to assess whether I'm more depressed. I have read that hypothyroidism in men is proven to cause libido issues.
