"Research finds finasteride causes penis shrinkage in rats"
>A new study in the Journal of Sexual Medicine finds that male rats receiving oral finasteride treatment for four weeks had a 25% reduction in the weight of their penis (corpora cavernosa).

>Studies have found penile shrinkage and other sexual dysfunctions to be a side effect of finasteride and dutasteride, common anti-baldness medications.
>Control groups that received dutasteride (C + D) or finasteride (C + F) showed a reduced cross-sectional penile area (39.4% and 40.1%, respectively) compared to Group C.

the results shown in rat testing suggest the need for human clinical trials. it should be highly concerning that preliminary trials show a large incidence and 25% shrinkage of penile tissue.
- well established that finasteride reduces the size of the prostate, which is also male reproductive tissue by 20%.
- well established that penile tissue in humans is responsive to dht.
- rodent studies are showing penile tissue (the same kind as prostate tissue) shrinks by roughly the same amount.
this is highly concerning. not something to handwave, conceal or dismiss.
>but anon it's rare!!!!
>1% incidence = common side effect.
