Basic Biochemistry
Here is what actually GROWS your penis, even without any penile exercising:
(DHT)-Dihydrotestosterone along with the prostaglandins E-1, E-2 and E-3 grows your penis and stimulate your penile cellular multiplication. In the same time the neurotransmitter acetylcholine and its derivative Nitric Oxide (NO) dilate the penile arteries for a constant penile blood circulation to supply testosterone, DHT, oxygen and the reductase enzyme 5-alpha to the penile tissue. Prostaglandin E-1 is very important because it allows the penile penile erectile, elastic tissues, nerves and blood vessels in the Tunica Albuginea and its Corpus Spongisosum and Corpus Cavernosa to expand and stretch without a collagen release. Additional testosterone and DHT production is stimulated by Prostaglandin E-2(which also grows your bone if there is enough Ca, Mg, Zn, Vitamin-D). ATTENTION here - without a reasonable level of prostaglandins E-1 and E-3 and Nitric Oxide, penile stimulation, such as - masturbation, stretching, pumping and jelqing, will induce excessive prostaglandin E-2 release(which will cause inflammation and abrasion) leading to collagen scaring of the penile erectile tissues and respectively penile shrinkage. DHT and prostaglandin E-2 can grow penile cells, actually any androgen-hormone receiving cells, good or bad (tumors or cancers).
The process is similar to pregnancy-induced enlargement of breast and abdominal tissues that grow without producing a collagen star(under the influence of prostaglandins E-1/E-2/E-3 and estrogen). For the penile enlargement it requires the united action of prostaglandins E-1, E-2, E-3, Nitric Oxide, DHT and Cyclic guanosine monophosphate(cGMP).
You have to think 3 times before doing penile exercises - stretching, bending or pumping your penis. Excessive stress hormones - epinephrine(adrenaline) and cortisol, excessive prolactin and estrogen, excessive blood sugar, certain medications or street drugs, alcohol, cigarette chemicals, deficiency of insulin, oxygen or androgen hormones (hGH, DHEA, testosterone, DHT and oxytocin), and deficiency of electrolytes WILL thin and harden the tunica albuginea and its sheathing spongy corpus cavernosa that will lead to:
- Erectile dysfunction
- Penile shrinkage
- Collagen scarring
Mechanically penile damage will surely induce collagen scaring of the erectile tissues.
REMEMBER - you have ONE and only ONE penis. So do not do hasty things before knowing what are you getting yourself into. If you screw up your penis this may be the end of your love-life! So take it slow and read the recommendations below.
The thing is that there is no muscle tissue in the penis, right, so when you get to the point that your spongy tissue do not produce sufficient amount of Prostaglandin E-1, your penile tissue, nerves and blood vessels will become inelastic. If you continue your exercises under these conditions you will be in a world of trouble. Firstly your stretching or bending will stimulate the tissue to stimulate fibrogenic cytokine over-expression. The Fibrogenic cytokine will stimulate collagen release for the scar tissue and fibroblast cells to grow over the damaged erectile tissue, leading to the erectile nervous dysfunction and the restriction of the penile blood flow in addition to damaging your penile nerve and blood vessel. From here only prostaglandin E-1 and Nitric Oxide will help you dissolve the scar tissue and restore proper penile function. After you continue beating up your penis, the Prostaglandin E-2 will be always present to inflame(NOT ENLARGE) your penis. Damaging and abrading the delicate penile spongy tissue and nervous fiber or ending, you can expect your penis to deform and weakly erect, or even entirely lose the erections. And if have the guts to continue, there is a fair chance that you will castrate yourself killing the testicular function.
