What does this video actually claim?
Ess Hödlmoser shares personal experiences comparing two rounds of low-dose testosterone therapy. The first was 8 months of testosterone alone, the second was a year with both testosterone and finasteride.
The creator emphasizes this is personal experience, not medical advice. They're documenting differences they noticed between the two treatment approaches. The video is part 3 of a 4-part series on their hormone therapy journey.
Is combining low-dose testosterone with finasteride evidence-based?
There's limited research on this specific combination for gender-affirming care. Finasteride blocks 5-alpha reductase, which converts testosterone to dihydrotestosterone (DHT). This can reduce androgenic effects like male-pattern baldness and body hair growth.
Most studies on finasteride focus on cisgender men with androgenetic alopecia or benign prostatic hyperplasia. The 5-year PLESS study (McConnell et al., NEJM, 1998) found 5mg daily finasteride reduced prostate volume by 18% in men with BPH.
For transgender individuals, some clinicians prescribe finasteride to minimize unwanted masculinizing effects while preserving desired changes. However, there's no standardized protocol or large-scale safety data for this population.
What are the potential risks they don't mention?
The creator doesn't discuss finasteride's side effects, which can be significant. The FDA warns about persistent sexual dysfunction, even after stopping the drug.
A 2011 study by Irwig found that 96% of former finasteride users reported persistent erectile dysfunction, with median duration of 40 months after discontinuation. Depression and cognitive symptoms have also been reported.
For people using testosterone therapy, finasteride might interfere with some desired masculinizing effects. DHT plays a role in body hair growth, genital development, and voice changes. Blocking it could potentially limit these changes.
What should you actually know about low-dose testosterone?
Low-dose testosterone protocols aren't standardized. Typical starting doses range from 25-50mg weekly, compared to 100-200mg for full replacement therapy.
The goal is often achieving masculinizing effects while maintaining some menstrual function or avoiding certain changes. However, testosterone effects aren't fully controllable regardless of dose.
A 2014 study by Deutsch found that even low-dose testosterone (25mg weekly) caused voice changes in 100% of participants within 6 months. The idea that you can pick and choose effects isn't supported by evidence. Individual responses vary significantly, and genetics play a major role in determining which changes occur first and how pronounced they become.
