What is antigen specific prostate?

Antigen specific prostate (dog) is a protein that is produced by healthy prostate cells in men. Protein produced in the prostate and is excreted in semen during ejaculation. Doctors use blood or urine measurement levels that measure prostate prostate levels as a means to explore the health of human prostate, in conjunction with other evaluation methods. Protein was first characterized in the 70s and the blood test of the dog was developed in the 80's. The first commercial blood test dog was released in 1986. This protein is produced by the prostate gland to integrate into the semen, the white fluid has released from the penis during ejaculation. The dog, which is also known as seminin and seminoprotein, improves the motility of sperm liquefaction of sperm. In addition, the protein helps to dissolve the mucus cap, which is present in the cervix that means the sperm to enter the uterus.

from discovery and characterization of protrumEin in the 60s and 70 years it was clear that the common name of the protein, the prostate specific antigen, was actually inaccurate. This is because the protein can be found in other tissues of the body and even in women. In addition to prostate and semen, a dog was also found in women's ejaculation, amnibium of fluid, breast milk, breast and salivary glands. Despite this, the PSA test is still valid for the purposes of prostate health assessment, because protein levels are increased in men who have prostate cancer and other prostate conditions.

There is some controversy about using the antigen test specific to the prostate for prostate health. One reason is that elevated dog levels are not only caused by prostate cancer. Only about one third who have a positive dog test actually have prostate cancer. The prostate naturally increases with age and other urogenital diseases can also cause prostate enlargement, so in addition to the dog test, other tests are also used, howo is physical examination and ultrasound, to make an accurate diagnosis.

Another aspect of controversy is that some studies suggest that the screening test of the PSA is not useful for reducing mortality due to prostate cancer and that long -term benefits for patients are uncertain. These studies have concluded that extensive dog screening results in unnecessary treatment of non -existent prostate problems, leading to chronic problems such as infection, erectile dysfunction and urinary incontinence. Many public and private medical organizations acknowledge these problems and suggest that men talk to their doctors about dog screening to consider risks and benefits.
