Heightened levels of HGH, DHEA, and testosterone in the bloodstream are needed in order to be able to naturally grow penile tissues by an average rate of 0.5 inches per year. After 25 it is considered that the penis cannot grow naturally, due to the inability of the human body to retain the levels of hormones needed, as well as the inability to keep active certain local receptors that are sensitive to the hormones.

The penile cellular multiplication is stimulated by the prostaglandins E1 E2 and E3, Nitric Oxide, along with DHT. Prostaglandin E1 is of great importance due to its effect on the penile erectile, elastic tissues, nerves, and blood vessels in Tunica Albuginea, Corpus Spongiosum and Corpus Cavernosa to expand and stretch without any damage or collagen release.

The method is about biochemically emulating the teenage growing process. The penile tissue must be made more elastic to be able to expand with the internal sexual energy.

In order to expand penile tissues naturally, a sufficient amount of HGH (Human Growth Hormone) and balanced levels of the crucial neurotransmitters ( Acetylcholine, Dopamine, Serotonin, Histamine and GABA) are needed. The body needs to be able produce suitable amounts of DHEA for increased elasticity in local penile tissues, as well as production of testosterone, estrogen and 5-alpha reductase. Optimal levels of estrogen for local blood vessels dilation are of great importance as well. Estrogen is important for its cooling effect on the sex organs that takes place during and after sexual excitement, while most of the testosterone is burned into bioelectricity and the end product – DHT. The burning of testosterone produces DHT (Dihydrotestosterone), resulting in tissue expansion and heating. It also produces bioelectricity that charges the nervous system, resulting in increment of nervous sensitivity. DHT (dihydrotestosterone) is also responsible for penile growth during adolescence. Without sufficient DHT, the penis will become defective. Testosterone and enzyme 5-alpha reductase are required to produce and mediate the levels of DHT. The liver should also be working properly, improper functioning will result in large amounts of the enzyme Aromatase that will convert testosterone and its precursors into estradiol – the most potent estrogen. For men, high levels of estradiol along with heightened levels of DHT in the prostate tissues may lead to prostate enlargement and cancers.

The penile expansion must be triggered by the brain and parasympathetic nervous system – no manual stimulation in order to achieve erection. If one can’t achieve one without physical stimulation, he won’t have the biochemistry to expand the penis either and there is much higher probability to end up with a broken penis and/or a collagen scar if any enlargement practices are attempted.
