These are the most relevant.
Ordera and Gontero (2010)
Read the whole thing
See: Multiple references regarding each of the tests. Note the methodologies.
Note: Gains from extenders have substantial evidence behind them from multiple studies. Gains are modest but seem to be real and relatively permanent (post-tests after months of no therapy whatsoever shows the same gains). To editorialise a bit, I\'d say that all these extender studies have one thing in common: tension on the penis over a long period of time. So I think hanging, which was not investigated, probably would be effective. This is the best paper I\'ve found, the most modern (unfortunately) and definitely collects the largest volume of evidence for consideration.

Ghanem et al. (2013)
Read: Surgical interventions and conclusion.
Notes: Generally regarding surgery. Length gains are not supported by much empirical evidence. Authors stated \"girth enhancement has been more successful as it did provide real increase in girth (3'4 cm), dependent on the take and type of the graft [28,38'43].\" Also many patients are not satisfied with results. Briefly reviews stretching studies, and concludes more complex double-blind studies with better education of subjects, etc are needed. Editorialisation: I completely agree. \"Limited data support the use of stretching devices for penile augmentation,\" but surgeries are near- not recommended.DOI: 10.1111/j.1743-6109.2012.02725.x (search this and you will find it)
Nikoobakht et al. (2011). Notes: \"Our finding supported the efficacy of the (penis extender Golden Erect) device in increasing penile length.Our result also suggested the possibility of a glans penis girth enhancement using the penile extender. Performing more studies is also recommended.\" Does not support penile shaft enhancement of girth, just head and length.
This is a newish study and the methods seem relatively solid. Wiley and Eardley (2007)
See: \"Physical Treatments\"
See: Referenes 30, 31, 32
Notes: Gains from extending devices, including phallosan, etc. Some of the treatment windows (20 m x 3 /each week) seem far less intense than what people generally do on PE forums. So be careful to look at methodologies, not just results. Also, this article is obsolete, since it is relatively old.

Conclusion:
To prepare for writing this, I read these again to a degree. Some themes emerge: literature is concerned with why men want an increase, I find this to be a point of bias. It should be conceptualised as a plastic surgery, and less emphasis should be placed on psychosocial interventions to convince patients they don\'t want what they want. That said, for some counseling may be effective.
Regarding Jelqing, the literature seems dismissive, but on closer inspection, I don\'t see evidence of either it working or not working. That is to say, no one did a study that I can find. Extenders are easier to study than jelqing because they are essentially standardized - everyone gets the same phallosan, the same Andropenis, etc. The subjects only need to learn how to operate it, and how long to leave it on, and then six months later, measure. For exercises, everyone is obviously different, some penises are larger or smaller, thicker or thinner, cut or uncut. It quickly becomes a methodological nightmare. And of course other factors, like grip, etc. are all concerns. On a personal note, I am very very uncut, so jelqing exercises for me require modification to be effective. There\'s just no way for me to do it as instructed.
Regarding surgery, it seems clearly indicated to be a thing of last resort with uncertain results and high dissatisfaction. Girth is obtainable, but length not so much from existing surgeries.
Regarding Penile extenders: evidence supports they increase length, and some evidence supports penis head increase. They probably do not increase girth on the shaft (though that last study from 2011 indicates they do). Most importantly: they do not decrease penis girth either (Ordera & Gontero, 2010, p. 1281); so it does not seem that one is simply streching out ones penis and losing girth. Rather something else is going on.
Where does this lead us? Penile extenders don\'t seem to be a waste of time.
If you have any questions, I\'d be happy to try to answer them.
