Prostate-specific antigen (PSA) is a protein produced by the prostate cells. It is normally present in small quantities in the semen ejaculate of men with healthy prostates. However, elevated levels are observed in cases of prostate cancer or other prostate related diseases such as prostatitis or benign prostatic hyperplasia. PSA liquefies the semen in the seminal coagulum and allows sperm to swim freely. It is also believed to dissolve the cervical mucus, allowing the entry of sperm into the uterus. PSA tests involve measuring of the PSA amount in the blood sample of patients.
Currently, North America dominates the global PSA Testing Market and is followed by Europe due to prostate cancer being most common type of cancer in men in these regions. Emerging economies of Asia-Pacific, Latin America, Middle East and Africa are also expected to undergo rapid market growth due to rising incidences of prostate related disorders.
