Loss of erection is brought about by increased outflow of blood from the penis.
How erection loss occurs Quick reduction in Cyclic GMP (substance that opens the blood vessels), is caused by another substance called phosphodiesterase.
This action reduces the inflow while increasing the outflow of blood from the penis, thus bringing about erection loss.
This process of erection ought to continue throughout the life of a man even as the sperm production also persists throughout the life span of a man.
However, we can make the following deductions from the erection mechanism: 1) Whatever that increases blood flow to the erectile tissues of the penis invariably increases the rate and strength of erection.
2) Whatever that blocks or impairs blood flow to the penis invariably decreases the rate and strength of erection, thus impotence.
The role of free radicals in impotence in men.
Recent scientific discovery in molecular medicine has shown that a certain group of molecules called free radicals are responsible for early sexual weakness in men or impotence in men.
The finding also proves that eradication of these elements from the body also amounts to eradication of the so-called sexual weakness of unknown origin.
Free radicals are unstable molecules generated in the body during metabolic processes.
They are very harmful to the body system if not checkmated.
Free radicals are mainly produced as free electrons during energy generation processes in the body particularly the "oxidative Phosphorylation" process.
During this process, four free electrons are released into the blood stream.
These unstable electrons ionize or charge the dissolved oxygen in the blood making them super active and destructive.
The products are called Superoxide or Peroxide free radicals depending on the number of oxygen molecules involved in the ionization process.
