The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
I would wager that a major effect of sleep deprivation on reducing testosterone and estrogen is not necessarily because of the lack of sleep per se, it's because usually when people are not getting enough sleep, they're getting too much light in their eyes in the middle of the night as well
Every Sunday: the week’s new conflicts and verdict changes — and nothing else.
Native comments, Twitter mentions, and Reddit threads about this claim — surfaced together so the conversation isn't fragmented across platforms.

viewing bright light with the eyes in the middle of the circadian night has a detrimental effect on dopamine, and therefore has a detrimental effect on things like testosterone and estrogen
avoiding bright light in the middle of the night is not just about not disrupting your sleep, it's also about optimizing the sex steroid hormones
what we know is that a night of total deprivation will markedly imper those hormones
they will have a level of testosterone which is similar to someone who is probably 10 years older than them
middle of the night you are suppressing dopamine release if you're suppressing dopamine release you are suppressing pressing testosterone levels
