So with all this data, why do u see a considerable amount of people complaining bout sides. I mean yeah sure, u could say that it seems so because the ones who do fine don’t complain, but still. From the day it would seem it’s very safe?!


Topical finasteride 2.275 mg/mL vs oral finasteride 1 mg vs placebo

24-week randomized trial:

OutcomeTopical finPlaceboOral fin
Treatment-related sexual AEs2.8%3.3%4.8%
No reported treatment-related sexual AE97.2%96.7%95.2%
Reduced/lost libido0.6%2.8%4.8%
Discontinued due to sexual AE0%1.1%2.4%
Sexual-function questionnaire: no significant difference between topical finasteride and placebo at 12 or 24 weeks.

Systemic exposure:

  • Maximum plasma finasteride: >100× lower with topical than oral
  • Serum DHT reduction: ~34.5% topical vs ~55.6% oral
Separate oral-finasteride 1 mg trials:

  • Decreased libido: 1.8% fin vs 1.3% placebo
  • ED: 1.3% vs 0.7%
  • Ejaculation disorder: 1.2% vs 0.7%
  • Decreased ejaculate volume: 0.8% vs 0.4%
  • Any reported sexual AE: 3.8% vs 2.1%
  • No reported sexual AE: 96.2% vs 97.9%
Oral finasteride 1 mg semen study:

  • No significant effect on sperm concentration
  • No significant effect on total sperm count
  • No significant effect on motility
  • No significant effect on morphology
  • Median ejaculate-volume change: −0.3 mL finasteride vs −0.2 mL placebo, not significantly different
Things not directly quantified in these trials:

  • Penis size
  • Penile sensation
  • Exact erection fullness
  • Fynzur-specific sperm quality/fertility over the long term
So based on the available data, is it fair to say the most likely outcome—especially with topical finasteride—is no noticeable change in libido, erection quality/fullness, penis size/feel, ejaculation, or semen parameters, while acknowledging that some of those specific outcomes were not directly measured?
