@sash1e's testosterone therapy story needs context

What did @sash1e actually say?

In a comedic storytime format, @sash1e walked through their pre-testosterone fears and told their past self, essentially, to relax. The claims were specific: testosterone made their singing voice "so much better" that they became a semi-finalist on The Voice, "bottom growth" became their "favorite side effect" and "alleviates all of your dysphoria," and hair loss happened but was something they "learned to live with." They also pushed back on fears about regretting transition, framing long-held gender identity as strong evidence of being trans. The video is comedy, not a medical tutorial, but with 566K views, the health claims land whether or not the creator intended them to.

Does the science back this up?

Partially, yes, and the parts that are wrong are more nuanced than dangerous. Testosterone does cause vocal changes in transgender men, clitoral growth (bottom growth), and androgenic hair loss in those genetically predisposed. What the science does not support is the idea that these effects are universally positive or predictable, and "alleviates all dysphoria" is a significant overstatement.

On voice: testosterone causes laryngeal growth and vocal fold thickening, which lowers pitch. A 2017 study by Azul et al. in the International Journal of Language and Communication Disorders found that vocal outcomes varied considerably among trans masculine people, with some reporting satisfaction and others reporting ongoing dissatisfaction or instability. Becoming a competitive singer is a real possibility, but it is not a guaranteed upgrade.

On bottom growth (clitoral hypertrophy): this is a well-documented effect of testosterone. It typically begins within the first few months. Research by Tamar-Mattis et al. and clinical data from UCSF's Transgender Care program confirm it is among the earliest and most consistent physical changes. Whether it alleviates dysphoria is individual.

On hair loss: @sash1e's candid admission that "we learned to live with it" is actually the most scientifically honest thing in the video. Androgenic alopecia in trans masculine people on testosterone is real, common, and not reversible upon stopping testosterone for most people.

What did they get wrong (or right)?

The biggest overclaim is that bottom growth "alleviates all of your dysphoria." That phrasing sets an expectation no body part can meet for everyone. Gender dysphoria is not a single-symptom condition. A 2021 systematic review by Aldridge et al. in Psychological Medicine found that hormone therapy significantly reduced psychological distress in many trans people, but individual variation was wide and some people required additional support including therapy and surgical options. "All" dysphoria going away from one physical change is not what the literature shows.

What they got right: the general direction of the effects they described is accurate. Voice changes, bottom growth, and hair thinning are all real, documented effects of testosterone in trans masculine people. Their framing of long-held gender identity as evidence of being trans aligns with clinical guidelines from WPATH and the Endocrine Society, which treat persistent, well-established gender incongruence as sufficient basis for care. The fear of "not really being trans" is common and clinically recognized. @sash1e's response to it, while profane, is not medically wrong.

What should you actually know?

Testosterone masculinization is well-studied, but individual outcomes differ. Here is what the evidence actually supports:

• Vocal changes from testosterone are permanent but not always linear or predictable. Some trans masculine singers report needing significant retraining. Working with a voice coach experienced in trans voice is advisable, not optional.
• Clitoral hypertrophy is nearly universal on testosterone and begins early, but its psychological effect ranges from profoundly relieving to neutral to distressing depending on the individual.
• Hair loss risk depends heavily on genetics. If you have family history of androgenic alopecia, testosterone increases your odds significantly. This is worth discussing with a provider before starting.
• Regret rates for gender-affirming hormone therapy are low in the literature. A 2021 study by Bustos et al. in Plastic and Reconstructive Surgery Global Open found regret rates of around 1% for hormonal interventions, though the authors noted study limitations including follow-up length.
• Dysphoria reduction from hormones is real and statistically significant across multiple studies, but it is not complete or guaranteed for every person. Mental health support alongside hormone therapy produces better outcomes than hormones alone.

This video is not medical advice and was not presented as such. But people watching it at scale will form expectations. Those expectations should be calibrated, not just excited.
