Really? Where is the scientific proof that vacuum pumping can’t increase the size?

Abstract
OBJECTIVE:
to assess the efficacy of vacuum therapy in mechanically straightening the penile curvature of Peyronie’s disease (PD).
PATIENTS AND METHODS:
Modelling of the tunica albuginea has been shown to be possible during penile implant surgery and this principle has been applied as an alternative conservative therapy. In all, 31 patients with PD (mean duration 9.9 months; mean age 51 years, range 24-71) completed the study. Over a 12-week period, the patients used a vacuum device (Osbon ErecAid, MediPlus, High Wycombe, UK) for 10 min twice daily. The assessment at study entry and at completion after 12 weeks included the International Index of Erectile Function questionnaire, a perceived pain intensity score, stretched penile length measurement and the angle of penile deformity after an intracavernous injection with prostaglandin E1.
RESULTS:
there was a clinically and statistically significant improvement in penile length, angle of curvature and pain after 12 weeks of using the vacuum pump. Of the 31 patients, 21 had a reduction in the angle of curvature by 5-25 degrees, three had worsening of the curvature and there was no change in the remaining seven. The curvature was corrected surgically in 15 patients while the remaining 16 (51%) were satisfied with the outcome.
CONCLUSION:
vacuum therapy can improve or stabilize the curvature of PD, is safe to use in all stages of the disease, and might reduce the number of patients going on to surgery."

Abstract
OBJECTIVE:
To assess the efficacy of a vacuum device as a noninvasive method for penile elongation.
PATIENTS AND METHODS:
Between September 2003 and November 2004, 37 sexually active men with a stretched penis length of <10 cm were given vacuum treatment three times a week, for 20 min on each occasion, for 6 months.
RESULTS:
After 6 months, the mean penile length had increased from 7.6 cm to 7.9 cm (no significant difference). The efficacy of vacuum treatment was approximately 10%, and the patient satisfaction rate was 30%. There was one case of haematoma of the penis and one of glans numbness, both resolved spontaneously without any intervention.
CONCLUSION:
Vacuum treatment of the penis is not an effective method for penile elongation, but provides psychological satisfaction for some men."

Interesting: 3mm gain on 7.6 cm is not significative?. I think a guy who is 6" wouldn’t dislike to gain 1/4" pumping for 20 minutes every other day (which is an improper routine for anyone interested in gains). Any reasonable person would take this study as an indice that vacuum pumping can be effective, and not just ‘apparent’.

You can call anything a scientific study, for example the self-reportings of the members of this site, but that doesn’t make good science. But so we’re clear from here on out, I meant accurate studies with large sample sizes and proven methodologies.
I call ‘a scientific study’ not what the staff of Mayo Clinic writes on his website trying to sell you penis enarlgement surgery, but what has been published on peer reviewd journals:

Abstract
INTRODUCTION:
It has been suggested that the application of penile-extender devices increases penile length and circumference. However, there are a few scientific studies in this field.
AIMS:
The aim of this study was to assess the efficacy of a penile-extender (Golden Erect(®) , Ronas Tajhiz Teb, Tehran, Iran) in increasing penile size.
METHODS:
This prospective study was performed on subjects complaining about "short penis" who were presented to our clinic between September 15, 2008 and December 15, 2008. After measuring the penile length in flaccid and stretched forms and penile circumference, patients were instructed to wear Golden Erect(®) , 4-6 hours per day during the first 2 weeks and then 9 hours per day until the end of the third month. The subjects were also trained how to increase the force of the device during determined intervals. The patients were visited at the end of the first and third months, and penile length and circumference were measured and compared with baseline.
MAIN OUTCOME MEASURES:
The primary end point of the study was changes in flaccid and stretched penile lengths compared with the baseline size during the 3 months follow-up.
RESULTS:
Twenty-three cases with a mean age of 26.5 ± 8.1 years entered the study. The mean flaccid penile length increased from 8.8 ± 1.2 cm to 10.1 ± 1.2 cm and 10.5 ± 1.2 cm, respectively, in the first and third months of follow-up, which was statistically significant (P < 0.05). Mean stretched penile length also significantly increased from 11.5 ± 1.0 cm to, respectively, 12.4 ± 1.3 cm and 13.2 ± 1.4 cm during the first and second follow-up (P < 0.05). No significant difference was found regarding proximal penile girth. However, it was not the same regarding the circumference of the glans penis (9.3 ± 0.86 cm vs. 8.8 ± 0.66 cm, P < 0.05).
CONCLUSION:
Our findings supported the efficacy of the device in increasing penile length. Our result also suggested the possibility of glans penis girth enhancement using penile extender. Performing more studies is recommended."

Abstract
OBJECTIVE:
To assess a commonly marketed brand of penile extender, the Andro-Penis(R) (Andromedical, Madrid, Spain), widely used devices which aim to increase penile size, in a phase II single-arm study powered to detect significant changes in penile size, as despite their widespread use, there is little scientific evidence to support their potential clinical utility in the treatment of patients with inadequate penile dimensions.
PATIENTS AND METHODS:
Fifteen patients were required to test the efficacy of the device, assuming an effect size of >0.8. Eligible patients were counselled how to use the penile extender for at least 4 h/day for 6 months. Penile dimensions were measured at baseline and after 1, 3, 6 and 12 months (end of study). The erectile function (EF) domain of the International Index of EF was administered at baseline and at the end of the study. Treatment satisfaction was assessed using an institutional unvalidated five-item questionnaire.
RESULTS:
After 6 months the mean gain in length was significant, meeting the goals of the effect size, at 2.3 and 1.7 cm for the flaccid and stretched penis, respectively. No significant changes in penile girth were detected. The EF domain scores improved significantly at the end of study. Treatment satisfaction scores were consistent with acceptable to good improvement in all items, except for penile girth, where the score was either ‘no change’ or ‘mild improvement’.
CONCLUSIONS:
Penile extenders should be regarded as a minimally invasive and effective treatment option to elongate the penile shaft in patients seeking treatment for a short penis."

"…in 2001, Scroppo and colleagues [10] reported the results of a small study that investigated the use of penile traction to treat PD curvature. Eight men with PD and no complaints of ED were instructed to use a penile traction device for at least 4 hours per day for a total treatment period of 3-6 months. The authors reported a statistically significant decrease in mean erect curvature of 14° (from 34 to 20°). However, this study involved a very small cohort of patients with no control group.
Several years later, Moncada-Iribarren and colleagues [11] reported on the use of a traction device to treat penile shortening that had occurred after PD surgery. A total of 40 men participated in this study, with 12 undergoing a grafting procedure while the remaining 28 underwent plication only. One-half of the patients were treated with penile traction and the other half served as the control group.
The penile extender was first instituted once the surgical incision had healed (approximately 2-3 weeks) for 8-12 hours daily for a total treatment period of at least 4 months. For both groups, penile shortening after surgery ranged from 0.5-4.0 cm. Those patients in the treatment group experienced a length increase ranging from 1-3 cm and this increase was proportional to the number of hours per month that the patient was wearing the extender. The authors also studied the potential impact of the device on the quality of life of their study groups and identified significant differences in several parameters for the patients using the device versus those in the control group.
In 2008, Levine and colleagues [12] reported the results of a study of 11 men with PD who underwent treatment with a penile traction device. All participants were evaluated with pre-treatment measurement of stretched penile length from pubis to corona, and a dynamic color duplex ultrasound was performed with measurement of curvature and girth at maximal erection. Of the 11 men who entered the study, one subject dropped out due to inability to comply with the treatment protocol. Patients were instructed to wear the device for a minimum of 2 hours per day but were encouraged to increase the duration of use to a maximum of 8 hours per day. Treatment was continued for a total of 6 months. Every 2 weeks, the extender rods were lengthened by 0.5 cm, and repeat length measurements were recorded every month during an office visit.
Of the 10 men who completed the study, all reported subjective improvements in length and curvature of 0.5-2.5 cm and 10-40°, respectively. Objectively, mean penile stretched length increased from 0.5-2.0 cm and curvature had been reduced by 10-45° (mean of 22°). There were no patient-described changes regarding penile sensation, worsening erectile function, or skin injury. Overall, patients reported high satisfaction rates and improvements in International Index of Erectile Function (IIEF) scores."

One can play the scholar skeptic and call this ‘not concluisve evidence’, but it is hard to deny that, far from being true that there are scientific studies who prove that PE can’t work, the few scientific studies performed show that PE can actually work and should by far be preferred to surgery.
