What did @socalurologyinstitute actually say?
A urologist at SoCal Urology Institute posted a short TikTok telling men on TRT to think twice before taking an aromatase inhibitor. His core argument: "most men actually are better with higher estradiol levels," and the old habit of suppressing estrogen came from fear borrowed from the anabolic steroid world, not from good evidence in TRT patients. He says he routinely sees patients with estradiol readings of 60, 70, or 80 and doesn't intervene unless symptoms are present. He also takes a shot at cookie-cutter clinics handing out anastrozole without clinical justification.
The practical recommendation he lands on is pointed: if a clinic gave you an aromatase inhibitor as part of a standard TRT package, "consider not taking it." That's a real clinical position, not a fringe take, and it deserves a careful look at what the evidence actually says.
Does the science back this up?
Yes, largely. The shift away from routine aromatase inhibitor use in TRT has solid research support, and the consensus among endocrinologists and urologists has genuinely moved in this direction over the past decade.
The case for leaving estradiol alone in men on TRT is built on several lines of evidence. Finkelstein et al. (2013, New England Journal of Medicine) showed that estradiol, not just testosterone, plays a significant role in regulating fat distribution, bone density, and sexual function in men. Suppressing it too aggressively produces real harms. A 2020 review by Ramasamy et al. in the Journal of Urology reinforced that estradiol is not simply a byproduct to manage, but a biologically active hormone men need. The Endocrine Society's clinical guidelines do not recommend routine aromatase inhibitor use in male hypogonadism. On gynecomastia specifically, the evidence that elevated estradiol from physiologic TRT causes significant gynecomastia in most men is weak. The gynecomastia concern was largely extrapolated from supraphysiologic anabolic steroid use, exactly as this creator says.
What did they get wrong (or right)?
They got the main point right, but a few things deserve pushback. The creator uses "rheumatized" and "rheumatase" throughout, which are mispronunciations of "aromatized" and "aromatase." That's a minor verbal slip, not a factual error, but it's worth noting in a video that's supposed to educate patients.
More substantively, telling viewers to "consider not taking" a prescribed medication based on a 60-second TikTok is genuinely risky framing. Context matters here. Some men do have symptomatic high estradiol, and some do develop gynecomastia on TRT, even at physiologic doses. The frequency is debated, but Shabsigh et al. (2005, Journal of Urology) found gynecomastia occurred in a meaningful minority of TRT patients in some protocols. The creator's "every once in a while" framing slightly undersells how individual variation works in practice. His broader point, that most men on standard TRT don't need an aromatase inhibitor, is defensible. The leap to suggesting patients self-discontinue a prescription is where the video overshoots.
What should you actually know?
Estradiol is not your enemy on TRT. The evidence is clear that men need estrogen for bone health, cardiovascular function, mood, and libido. Crushing it with anastrozole when there's no clinical reason to do so is a mistake, and a common one at lower-quality TRT clinics chasing a number on a lab panel instead of treating a patient.
That said, "I feel fine" and "the number doesn't bother me" are not the same as "this is safe for everyone." Estradiol above 40-50 pg/mL is considered elevated by most reference ranges for men, and while many patients are asymptomatic, some are not. The right move is a conversation with your prescriber about your specific symptoms, labs, and protocol, not a TikTok-driven decision to stop a medication.
- If your clinic gave you anastrozole as a default, ask why. If there's no clear clinical reason, that's a fair question.
- Do not stop a prescribed medication without talking to your provider first.
- Aromatase inhibitors have real side effects, including joint pain, bone density loss, and sexual dysfunction from over-suppression of estradiol.
- The right estradiol target on TRT is individual and symptom-driven, not a single lab number.
