The headline is broadly defensible, but the qualifications matter. Effect sizes vary by population, the strongest claims rest on shorter trials, and credible voices push back on how it's typically framed.
In fact, the concentration of intratesticular testosterone is at least 100 times higher than the concentration of testosterone anywhere else in the body, even though it's being secreted into the rest of the body. And that's because there are a number of different so-called binding proteins and enzymes that sequester the testosterone within the testes.

and the other sort of reason that sperm production is lost with exogenous testosterone uses is actually the in testicular testosterone is much higher than serum levels so you know our serum levels are you know between 300 and 900 uh NRS per deciliter on average but in the testicle are probably 10 fold higher at least so when men are given exogenous testosterone they not producing their own the levels of testosterone in the testicle which are necessary for sperm production are much much lower
