You're getting downvoted, but I'm not entirely sure why. It's not some toxic Andrew-Tate-esque take to consider low testosterone as a possibility for the lack of drive the author mentions.
Personally, I plan on doing it soon, there's no harm in it.
T levels aren't everything, though. Get a full hormone panel. I got one and found my adrenals weren't producing enough DHEA.
Also note that HRT, and specifically testosterone supplementation may not address core issues. I was a candidate for test, but this would have allowed my adrenals to stay suppressed and ruined my balls.
