Targeting the Tunica
Targeting the Tunica (Part 1)
Note: This article/thread is an attempt get a forum focus on overcoming the limits of the tunica. I am not a scientist, physiologist,
biologist. The following contains simply my opinions and theories. They are not meant to be taken as gospel but to be a catalyst
for forward thinking.
Know your enemy…
With any endeavour in life there is always some limiting factor that affects the outcome.
In PE, it is widely recognized that the tunica albuginea is the adversary we must overcome to continue to make length gains.
For you newbies here’s a brief overview.
The tunica is the whitish membrane within the penis that surrounds the spongy chambers (corpora cavernosa)
in the penis and which helps to trap the blood in the corpora cavernosa, thereby sustaining erection of the penis.
The term comes straight from the Latin tunica (covering or coat) + albuginea (white) = a covering that is white,
like the white (albumen) of an egg.
The tunica albuginea, is stretched tightly enough to produce rigidity. In addition to defining the shape of the
erect penis, the tunica also has a key role in limiting blood outflow during erection.
So in at least on aspect, the natural function of the tunica is to do exactly what we don’t want, limit the size of
our penises and its composition and design are very effective at doing this.
The tunica plays an important role in the mechanism of erection because of it is essential for penile extensibility,
rigidity, compliance, and veno-occlusion; it is composed mainly of thick collagen bundles and elastic fibres. The
former are arrayed in two layers; the inner is circular, the outer longitudinal. Collagen fibres are composed of
the aggregation of tropocollagen molecules and normally are arranged in an undulating pattern in the flaccid state.
Although their tensile strength is great, their elasticity is limited as a result of the molecular configuration.
Elastic fibres, which are composed of elastin and micro-fibrils, can stretch to 150% of their normal length.
In my personal humble opinion I believe this is the number one limiting factor for length gains.
Girth gains are another topic and could be attributed to CC “struts.” See ModestoMan’s thread
CC “Struts” may limit girth growth
Anyhow, Evidence to support the tunica as the length limiter can be found in saphenous vein grafts studies.
Saphenous vein graft is a process in which the tunica is cut and a segment of vein is grafted in.
Below is the results of grafts on several patients suffering from Peyronie’s disease.
Saphenous Vein Grafts
We have performed this procedure on seven patients with moderate erectile dysfunction and severe penile
shortening from Peyronie’s disease. One patient who did not use the VED (vacuum erection device, i.e. “pump”)
gained 1 inch of length while all the others who did use the VED gained 2 inches at 6 months.
All patients reported decreased rigidity with erections, but the VED was effective in inducing erections
adequate for intercourse. All patients were satisfied with the regained length achieved by the surgery.
Two patients subsequently underwent implantation of an inflatable penile prosthesis without difficulty.
Successful artificial tissue expansion has been described in the orthopedic literature (Ilizarov technique).
12 Attempts to lengthen the penis have for the most part failed in the past with the use of weights, severing
the suspensory ligament, etc. These procedures have improved flaccid length in some cases but not erectile length.
Since the tunica tissue is fibrous and rigid, use of a VED to stretch this tissue does not result in long-term
gains in erectile length.13
According to these studies, introducing a flexible tissue into the tunica resulted in length gains of 2” over a period of
only 6 months.
So now, how do we target the tunica? I think in this instance it is entirely appropriate to apply body building principles
to PE. How so? In body building the optimal way to target a muscle is isolation. In PE this may prove to true also.
The goal here would be to fatigue the tunica to a point past the tensile strength and trigger some type of growth or injury/
remodeling response. Some noted exercises that are good in this respect is the V-Stretch, Inverted V-Stretch and fulcrum stretch.
I use a variation of the V-Stretch in something I call the “Hook Stretch.” I hold the glans with one hand and stretch as far our
as I can. I use the index (thumb or pointer will work) finger and form a hook with it. I move the “hook” up and down the shaft
like a fulcrum a finger width at a time. After several sets the tunica becomes sore.
There are various threads that explore chemically breaking down the tunica to maximize the effectiveness of applied stress but
most of these are quiet theoretical and have not been explored.

Let me tell you the secret that has led me to my goal: my strength lies solely in my tenacity.
