Polyphenols and Farfetched Dream in Prostate Cancer Treatment - Amir Valizadeh - Bog

Prostate is an important gland in the male reproductive system. When healthy and in men younger than 50, it is usually the size of a walnut and weighs about 0.75 ounces. The prostate is located in the abdomen, in front of the rectum and between the penis and the bladder. The urethra is the same tube that carries sperm from the testicles and urine from the bladder through the penis and also passes through the prostate. This gland plays a role in male fertility and produces and secretes prostate fluid, which is a part of semen. During ejaculation, sperm move from the testicles through a series of tubes. This causes the prostate muscles to contract in the urethra. This causes the urethra to become blocked from any urine passing through it. Then the semen can enter the urethra and the prostate fluid is released and mixed with the semen from the testicles. Prostate fluid contains an enzyme called prostate-specific antigen (PSA). PSA helps to thin the semen. This source contains enzymes, citric acid and zinc. This fluid is one of the parts of semen that helps protect the sperm. In particular, semen is chemically basic.
