I think most people here have this, although perhaps not everyone is willing to talk about it, as what can be more humiliating and emasculating to a man than this? I have had no improvement in that (or any other) area – in fact I have had a deterioration – in the 2.5 years since i’ve stopped Finasteride.
In the animal trials of Finasteride with rats, penile shrinkage is a common, not a rare, effect. It would be interesting to read these papers and figure out what percent of rats had this effect, as opposed to mean change in penile mass/volume.
