Introduction:
When the human tissues are submitted to a force of traction,
they react by increasing in size.
The principle of traction is applied in modern medicine,
for the generation of new tissue to cover burn wounds or
areas of hair loss ( placing a tissular expander underneath
the normal skin ) or for the lenghthening of bones.
In other cultures this principle is applied to lenghthen
different parts of the body like the Giraffe Women of the
Paduang tribe in Birmania ; or the lenghthening of the lips
in certain African tribes of Africa that use wood to create
traction; and in India where they hang stones on the penis
of men as a form of penitence with the resulting enlargement
of the organ.
Based on this principle of external traction the Andro-Penis®
was designed . It is able to exhert a gradual traction force
of 600 to 1500 grams.
The device consists of a plastic ring, where the penis is
introduced and from where 2 dynamic metalic rods that originate
the traction. In the superior part there is a plastic support
where a silicone band holds the glans in place.
Based on our
clinical experience the traction device yields the following
resutls:
An increase in the lenght of the penis
in erection and flaccidity.
An increase in the perimeter of the penis
in erection and flaccidity.
This results will be analyzed statistically
to be verified and quantified see
next

3.1.- INCREASE IN LENGHT
IN ERECTION:
The increase in the length
of the penis in erection, is relative to the
length of time in which the device is worn.
Such growth is lineal as is observed in the
chart. This translates in: the longer the time
of use, the more lenght is obtained.
The lineal correlation coefficient between time
of use and increase in length in erection is
of 0.760 ( p=0.000 ).
|
| |
The average increase in the
length of the penis in erection by month is of
0.4726 cm. The standard deviation is of 0.1329
cm. The confidential interval of 95% is of [0.4283
; 0.5169] which indicates a minimal gain in the
population of 0.4283 cm/month.
|
| |
Regression line is:
DL erec = - 0.327 + 0.562 x t
This calculation will allow us to estimate the
increase in length of the penis in erection, based
on the months of use of the device. There is a
57.7% variance in the increment in longitude,
which is explained by the variance in the duration
of treatment ( R2= 0.577 ). The other 42.3% is
due to other differences innate to each individual
and not relative to the
duration of the treatment.

IN THE FLACCID STATE
|
3. Results
3.3.-
VARIABILITY:
The variability in the increment
in longitude in erection is different from that
of flaccidity, being the difference in variance
significant ( p= 0.003 ) which indicates a greater
dispersion of the increases in length during flacidity
than in erection.
|
|
3.4.- THE INCREMENT IN LONGITUDE
DOES NOT DEPEND ON THE AGE:
A very interesting result
was that the increment in longitude does not
depend on the age of the patient, since the
coefficient of the linear correlation is not
significant ( r=0.008, p=0.961). In other words,
the age of the patient does not effect the increment
in longitude.
|
| |
| |
|
3.7.- LONGITUDE INCREASE
IN ERECTION STATE DEPENDING ON USE:
Dividing the population
studied in four sub groups depending
on the usage time of the Andro-Penis®.we
obtain the following results.
Three months usage:
The median longitude increment in erection
state was 1.4118, obtaining a median
growth of 10.5580% over the initial
longitude.The confidence interval of
95% of the studied population was (
1.1522; 1.6713) which shows a median
minimal growth of 1.1522 cm in three
months.
Four months usage:
The median longitude increment in erection
state was 1.8462, obtaining a median
growth of 14.1113% over the initial
longitude. The confidence interval of
95% of the studied population was(1.5809;
2.1114) which shows a median minimal
growth of 1.5809 cm in four months.
Five
months usage:
The median longitude increment in erection
state was 2.2750, obtaining a median
growth of 16.6303% over the initial
longitude. The confidence interval of
95% of the population studied was (1.7656;
2.7844) which shows a median minimal
growth of 1.7656 cm in four months.
Six months usage:
The median longitude increment in erection
state was 3.3333, obtaining a median
growth of 27.5% over the initial longitude.
The confidential interval of 95% of
the population studied was (2.8162;
3.8504) which shows a median minimal
growth of 2.8162 cm in six months.
The samples corresponding to five and
six months are very small which makes
small intervals and less reliable.
|
| |
|
| |
|
3.8.- DISTRIBUTION:
Although the variables
considered in the population are not normal,
the median samples, have normal distribution
since the amount of the sample is greater
than 20.
