Firm Flaccid Penis
A hard flaccid penis is a fairly common problem to men who injured their penises. In order to reverse the condition you have to understand the biochemical (electrical) processes that caused it in the first place.
If you masturbate chronically or use penile enlargement techniques, there is a fair chance that you will injure your penis beyond the point of self repair. Over-masturbation, over-ejaculation or other excessive stressors over-discharges the brain's acetylcholine, dopamine, and serotonin nerves systems. An excessive Prostaglandin E-2 release into the blood and tissues is also observed. The biggest problem associated with overmaturbation or over-ejaculation is the deactivation of the Central Nervous System (CNS) that drives the hypathamalus and anterior pituitary, the master of the endorine function for hormonal production, and powers the entire endocrine function through the parasympathetic nervous division - the bioelectric backup battery. Over-maturbation or over-ejaculation fully consumes testosterone and leaves nothing to recharge the CNS and the parasympathetic backup battery - it is as you have drained your car battery and cannot start the engine to recharge it.
The production of your androgen hormones - DHEA, testosterone, androstenedione and DHT and pituitary oxytocin becomes too low(as a result of the exhausted pituitary-adrenal and testicular axis) to suppress prostaglandin E2(an inflammatory hormone) release from your body. Other excessive stress hormones prolactin, cortisol, noepinephrine and epinephrine(adrenaline) can also induce excessive prostaglandin E-2 release from the tissues. Excessive prostaglandin E2 in the bloodstream causes not only inflammatory, but also weak neuro-immunity.
Excessive stressors epinephrine or/and cortisol, prostaglandin E-2, medication or street drugs, excessive blood sugar, excessive prolactin and estrogen, alcohol, cigarette chemicals, deficiency of insulin, deficiency of oxygen, deficiency of androgen hormones (hGH, DHEA, testosterone, DHT and oxytocin), and deficiency of electrolytes will thin and harden (reduce the elasticity and expansibility of) the tunica albuginea and its sheathing spongy corpus cavernosa for erectile dysfunction, penile shrinkage and collagen scarring. As a result, the sexual exhaustion produce multiple symptoms which become UFO for the western doctors and medical societies since the western doctors and medical societies fail to realize the root of the problems.
A mechanical penile damage will induce hardening and a collagen scaring of the erectile tissues(by the uncontrolled release of prostaglandin E-2) when you expand it up beyond the elasticity that your tunica albuginea can endure (physically and biochemically for the repair needed). Please, think 4 times before jelqing, stretching, hanging or pumping up your penis!
You have to BOOST your prostaglandins E-1/E-3 and Nitric Oxide (cGMP) release from the adjacent healthy erectile tissues to soften the collagen scar or prevent collagen scar formation (it will also heal the damaged penile erectile, elastic tissues, nerves and blood vessels in the tunica albuginea and its sheathing spongy corpus cavernosa). A good way to do this is by using right combination of amino-acids, herbs, and vitamins & minerals.
