Can physique and gluteal size predict penile length in adult Nigerian men?
Orakwe JC, Ogbuagu BO, Ebuh GU.

In Nigeria, especially among the Igbo tribe, there is a well-held belief that a man’s penile size can be predicted from his physique and the size of his buttocks, with people of small physique and flat buttocks likely to have long penile lengths.

A prospective study to test the scientific veracity of this traditional and apparently mythical belief. Stretched penile length was measured in 115 men between the ages of 30-65 years and its correlation with the body-mass index and the circumference of the hip as measured around the most prominent points on their buttocks, was statistically determined.

The mean age of the subjects was 42.30 years (SD = 9.67), with a median of 40 years and a range of 30-65 years. The mean penile length was 13.37 cm with a median of 13 cm and a range of 7.5-19.5 cm. The mean circumference of the body around the buttocks was 96.46 cm (SD = 10.91), median 98 cm, and range 73-122 cm. The body-mass index ranged 17.34-44.44, with the mean at 26.87 (SD = 5.86), and the median 25.53. Linear regression statistics showed no statistically significant correlation between stretched penile length and body-mass index, thus physique. There was a significant direct correlation between penile length and gluteal size.

The supposed relationship between penile length and gluteal size may have a scientific basis, but contrary to belief, large buttocks is more predictive of longer penile length than small buttocks. Penile length has no relationship to physique.

In conclusion, penile extenders have been shown to be an effective minimally invasive method of penile lengthening and could become a first-line treatment option for patients seeking a penile lengthening procedure. In the field of medicine, however, these devices should be reserved for patients with a ‘ true ’ short penis. In the setting of unregulated self-medication, where vulnerable patients explore every kind of penis-enhancement procedure, penile traction therapy should be under the control of physicians, and not of deceptive advertisements.

Abstract: Penile lengthening methods remain a controversial issue. Surgical procedures of ‘lengthening phalloplasty’ are characterized by poorly defined indications and an unacceptably high rate of complications, as recently outlined by a literature review, while non-surgical techniques are largely popularized by the media but often lack scientific evidence. In the literature we found only ten articles/abstracts of studies pertaining to the topic of our review. With our review, we aimed to explore whether non-surgical methods of penile lengthening may have some scientific background. We focused specifically on penile extenders, which among conservative methods are those whose efficacy is supported by some scientific evidence. It seems that penile traction devices should be proposed as the first-line treatment option for patients seeking a penile lengthening procedure. Penile size is a matter of great interest among men who are affected by ‘short penis syndrome’ or just believe themselves to have a small penis, even though the dimensions of the organ fall within the normal range. Surgical procedures of ‘lengthening phalloplasty’ lack standardized indications and carry a high risk of complications. Several non-invasive methods of penile lengthening have been described, such as vacuum devices, penile traction devices and penoscrotal rings; even ‘physical exercises’ have been popularized through the media. Most of these techniques, however, are not supported by any scientific evidence. We briefly analyse the efficacy and scientific background of such non-surgical methods of penile lengthening. It seems that penile extenders represent the only evidence-based technique of penile elongation. Results achieved do not seem to be inferior to surgery, making these traction devices an ideal first-line treatment option for patients seeking a penile lengthening procedure.

I have PDFs of these articles that I pulled from Google scholar but I wasn’t sure if putting them on here was okay (copyright and all).

Thanks FG. If those documents are pubblicly accessible, they are ok but we need a link to them. I think those studies were already posted here.

I don’t know if here is the right place to post it; if not, I’m sorry- feel free to eliminate this post.
I translated some of my posts from Spanish into English. You can access them through my signature as well:

1) An illustrated vocabulary of external anatomy of the penis. 10 illustrations (the last one, about secretions, is on page #3) with a very detailed vocabulary. It’s full of information about the parts of the penis. Some readers said now they really know that what they considered a disease is actually a normal part of the penis. The original version in Spanish is kept in the Library (La biblioteca), with another useful articles.

2) If you want to gain length, this is your routine, proved with success by a lot of people in the Spanish forum:

3) The application of PNF (proprioceptive neuromuscular facilitation) is very simple and it leads to a longer stretching:

Penile extensibility: to what is it related?

“The extensibility decreased with patient age but it was not influenced by removal of the skin and/or cavernous tissue. No correlation was observed between decreased extensibility and the increase in fibrotic elements in the penile tissue. Penile extensibility seems to reflect the elasticity of the tunica albuginea, which is the limiting factor and cannot be an expression of fibrosis of the corpora cavernosa.”…sj.ijir.3901272
“The decrease in length in impotent men in this study could be explained by the loss of elastic fibers, and the lack of intermittent stretching in the tunica albuginea, confirming the common saying (if you do not use it you lose it).”

A Pilot Study to Determine Penile Oxygen Saturation Before and After Vacuum Therapy in Patients with Erectile Dysfunction After Radical Prostatectomy.

Author information
Provoked and spontaneous nocturnal erections are thought to play a role in maintenance of male sexual health through oxygenation of the corpus cavernosa. Conversely, hypoxia is thought to be an etiological factor in the pathogenesis of cavernosal fibrosis and long-term erectile dysfunction. It has been hypothesized that the early penile hypoxia after radical prostatectomy (RP) may lead to fibrosis and consequently a decrease in stretched penile length and long-term erectile dysfunction.
The aim of this study was to assess the changes in penile tissue oxygenation with vacuum erection device (VED) use.
Twenty men between 2 and 24 months following RP were enrolled prospectively. Each man cycled a VED to achieve full erection 10 consecutive times over a period of approximately 2 minutes without constriction ring.
Tissue oximetry was measured at baseline and immediately after VED using a tissue oximeter at five sites: right thigh, right corpora, glans, left corpora, and left thigh. Additional measurements were captured over the course of an hour.
Mean age and time from surgery was 58.2 years and 12.6 months, respectively, and the average Sexual Health Inventory for Men score was 7. Use of the VED significantly increased both glanular and corporal oximetry relative to the baseline values for the entire 60 minutes. An initial increase of 55% was seen in corporal oxygenation with VED use.

This is the first study demonstrating that [b]a single, brief application of the VED without a constriction ring results in significant improvement in penile oxygen saturation. The use of a VED has significant benefits for patients both with regard to cost and invasiveness when compared with other penile rehabilitation protocols.

I always wondered how pumping might add girth to someone. Now its even less clear, they’re basically saying pumping raised oxygenation, hence should not cause fibrosis.

Marinera you have any thought about what is happening during/after pumping?

That would be an interesting topic for a new thread Mister N. ;)
