I read the full study. It's simply conjecture to assume the similar penis-positive effects will occur unless you are 12-24 years of age with the diagnosed condition as the same or similar to the sample group. I mean... it could work! But this study doesn't directly indicate that if you do not have micropenis that you will have similar results. The mechanics of how and why the effect is arrived at are not studied, only the effect on a very select group of people. It could have simply no effect if your testosterone levels are normal or were normal during puberty. It could have no effect if you are not in the age range (as puberty is nearly universally complete in adult males over 24). Interestingly I think it could also have a similar measure effect of statically assigned gains to your starting length (I assume we just care about penis length) of roughly 2cm increase. It could have a scaled proportional effect of adding about 37% increase in length (this seems intuitively unlikely, that a 6' would go to 8.26', thinking of my own (20cm going to 27.54cm) makes it really seem like a ludicrous expectation... final party-pooping: I don't see where in the study they normalize the results of taking the measurements during puberty (a period in which it would normally be expected for young men's penises to increase in size naturally during a 24 week period). I don't see the participant level data and so we can't actually see if the average measured effect is brought about by a subgroup (Im thinking like, the young people in active puberty) skewing the results. The study results may be a flawed conclusion of a normal phenomenon as there is no control group present who received no treatment (or did I miss that?).
Anyway, this does seem like a relatively safe alternative to subdermal filler injection or any of the other mechanical methods, so I'm pretty keen on seeing your anecdotal response to the treatment particularly if you are 25 years old+ and not suffering from micropenis, as an anecdotal response from you would indicate very likely that the treatment does generally have some effect on penis size, assuming you're doing nothing else simultaneous to the same end.
It's really cool to see another approach, and interesting to think that the resource is readily available, relatively cheap, and able to be self administered.
Thanks!
