A few times, Dr. Jamin Brahmbhatt suspected he might have low testosterone.

But when he checked his numbers, he discovered they were entirely within a normal range.

"Turns out it was more so my sleep and stress and everything else," says Brahmbhatt , a urologist at Orlando Health in Florida.

Brahmbhatt treats men with low testosterone every day — meaning he's on the front lines of the current cultural fixation with testosterone.

Social media is overflowing with testosterone content, from fears of "low T" to " 't-maxxing "' tutorials. Influential voices, including the podcaster Joe Rogan and Health Secretary Robert F. Kennedy Jr., are openly discussing their own use of testosterone therapy. And there's a huge industry of online clinics that make it easy for anyone to get a prescription.

Brahmbhatt welcomes the increased attention to men's health — and hormone replacement therapy specifically –– which he says has been "ignored" for too long.
