I am 37yo.

One year ago I did a checkup and asked for my testosterone levels because I was feeling my libido was lower than normal.

The results came back and my numbers were 377 ng/dL, free test was 9 ng/dL and SHBG 23,6 mmol/L.

It was low, but within the normal range.

Everything else was perfectly normal.

Now almost a year later I am feeling that things are worse. I can go a week without feeling any desire. I still have morning wood, but it is not every day like it was. I have sex with my SO, but I can easily lose my erection.

I scheduled an appointment with an endocrinologist from my health inssurance, but it has a spot only in July!

So I went to a lab and did a blood test for testosterone and it is indeed worse.

It is now 255 ng/dL, free test was 6,5 ng/dL and SHBG 19 mmol/L.

I am physically active, lift weights 4 days per week, can squat relatively big numbers, am not overweight (on mornings I have a six pack) and drink alcohol only on weekends.

Is this drop normal when you reach 40s or there is probably an issue here?

I thought HRT was for when we were in our 50s.

Anybody has gone through anything similar and can share your stories?
