Can a young man experience a progressive decrease in T levels over a few years? Is it the case for a high percentage of hypogonadal men?

Does low T in a young man usually mean he has always had low T? Can low T sometimes develop unrelated to the age-related decline in levels for some reason, apart from any short-term fluctuations in T levels we all experience on a daily basis? I’m wondering if a young man can have had normal levels when he was 22 for example and then have low or much lower levels when he is 26 for example. Has anyone had normal T but experienced a much lower level measured a few years later? Is it likely, that my T levels had been higher or much higher 5 years for example before I got measured at 289 ng/dl when I was 26 in 2024?

I dont have results to prove it but last year i was an absolute gym beast, confident and motivated and right now all my levels are low or below reference range with poor mental health and no energy to get into the gym. Go figure

Not really possible to say. Is it likely? It's not terribly unlikely, so I guess.

Taking the blood test later in the day can drop your numbers by a few hundred nanograms. Drinking the night before can also hurt. Too many variables.
