Stenosis (narrowing) of Uro-genital channels and its Consequences: Generally, the stenosis (narrowing) of the uro-genital domain develops asymptomatic. Stenosis begins very slowly and approximately and it usually makes itself noticeable at age 40. Stenosis can be accelerated via stress, heavy lifting, and bad nutrition. At the beginning, stenosis of the uro-genital system reduces the volume of vessels (channels). Activities like weightlifting and stress increase the stenosis. Flow of secretions through the vessels will be gradually blocked. Disturbed circulation of blood (ischemia) in the uro-genital domain makes itself noticeable. Prostate ischemia especially makes itself noticeable. Blocked flow of secretions and ischemia occurs at the same time (simultaneously), which causes disturbed circulation at the prostate gland. Testosterone is a hormone, which is produced in the testes. Testosterone hormone circulates in the blood. Testosterone is transported by means of protein (carrier molecule) to the prostate. Because of the disturbed circulation, the testosterone hormone cannot reach the prostate.This means the prostate is now deficient of the testosterone hormone. Deficiency of testosterone causes the prostate to be unable to produce its secretions. The prostate gradually begins to enlarge because of the testosterone deficiency. The enlarged prostate gradually narrows the urethra. The consequence of a narrowed urethra is disturbed urination.
