Aspartame damages the hypothalamus. The hypothalamus produces gonadotropin-releasing hormone (GRH). The GRH goes down the stalk between the hypothalamus and pituitary and causes the pituitary then to produce gonadotropins. The ganglia goes to the testicles and causes them to produce testosterone. When you're causing hypothalamic destruction with neuroexcitotoxins like NutraSweet you're suppressing the formation of male hormone without which there is no sexual drive or pleasure for either. In original studies aspartame triggered atrophied testes and testicular tumors. It is by this route.
Aspartame destroys the myelin sheaths and when that happens the nerves and sheaths try to regenerate but now the signals can be crossed. So the pleasure receptor of the penis sends the signals but it arrives at the brain at a different receptor and not recognized as pleasure. Also, the ganglia collections of nerve sheaths and cells that are kind of little mini brains that lie inside the thorax and abdomen in front of the spinal cord are important in both sexual arousal, penile tumescence (erection) and in producing orgasm. The methyl alcohol type of poisoning from NutraSweet is the foremost known cause of degeneration of the sheaths and the ganglia. Also methyl alcohol type poisoning is the foremost known cause of antimyelin antibodies , so that thereafter the immune system can carry out similar destructions in the absence of aspartame. Now the excitatory area of the cerebral cortex which allows men to be excited, interested and pleasured by sex atrophies when the testosterone is suppressed. Moreover, you have an independent neurotoxin generated by the isolated phenylalanine. Anytime you have a neurotoxin making the brain sick sexual pleasure is obliterated because the brain is the most important sexual organ. You have classic alcohol poisoning and alcoholism and alcohol poisoning is notoriously famous for wiping out the male animal.
Serotonin and dopamine levels are suppressed. With your serotonin, dopamine and other neurotransmitters in the brain obliterated life becomes one long, dark, hopeless, sleepless, pleasureless night. Turns the goodness of sex into a wistful memory instead of a reality. Pepsi isn't so peppy after all!
