"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).
Effects of oral finasteride on erectile function in a rat model:

>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.
it's very well medically established that finasteride reduces the size of the prostate, which is also male reproductive tissue by 20%.
it's also very 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.
