The prostate (from the Greek προστάτης - prostates, literally "a State before", "protector", "guardian" [1]) is a composite tubuloalveolar exocrine gland of the male reproductive system of mammals. Women do not have a prostate gland, but women have microscopic Skene the paraurethral glands connected to the distal third of the urethra in the prevaginal space that are homologous to the prostate. The main function of the prostate is to store and secrete a clear, slightly alkaline (pH 7.29) moisture that is 10-30% of the volume of seminal fluid which, together with sperm, the sperm. The rest of the seminal fluid is produced by the two seminal vesicles. The alkalinity of seminal fluid helps neutralize the acidity of the vaginal tract, the extension of the life of the sperm. The prostate part of the urethra develops from the pelvis (middle) part of the urogenital sinus (endodermal origin). Endodermal outgrowth resulting from the prostate a part of the urethra and grow in the surrounding mesenchyme. The glandular epithelium of the prostate distinguishes this endodermal cells, and the associated mesenchyme distinguished in the dense stroma and the smooth muscle of the prostate. [2] The prostate glands represent the modified wall of the proximal portion of the male urethra and created by the 9th week of embryonic life in the development of the reproductive system. Condensation of mesenchyme, urethra and Wolffian channels gives rise to the adult prostate gland, a composite body comprising several glandular and non-glandular components tightly fused into a single capsule. Within the prostate, the urethra from the bladder to the urethra, the prostate and merges with the two Ejaculatory channels. (The male urethra has two functions: to transport urine from the bladder during urination and for the transport of semen during ejaculation.) The prostate is sheathed in the muscles of the pelvic floor, which contract during the Ejaculatory process. Benign prostatic hyperplasia (BPH) occurs in older men, [6] the prostate often extends to the point where it becomes difficult urination. Symptoms include need to go to the toilet often (pollakisuria) or take a while to get started (doubt). If the prostate grows too large it may constrict the urethra and impede the flow of urine, making urination difficult and painful and in extreme cases completely impossible. BPH can be treated with medication, a minimally invasive procedure, or, in extreme cases, surgery that removes the prostate. Not less invasive procedures include Transurethral needle ablation of the prostate (tuna) and Transurethral microwave heat therapy (TUMT). These outpatient procedures could be followed by the insertion of a temporary Prostatic stent, so that the normal urination voluntarily, without exacerbating irritative symptoms [7]. The surgery typically used in such cases is transurethral resection of the prostate (TURP or TUR). In TURP, an instrument is inserted through the urethra to remove prostate tissue that is pressing against the upper part of the urethra and restricting the flow of urine. Older men often have corpora amylacea [8] (amyloid), dense, calcified protein material, in the channels of their prostates. The corpora amylacea may obstruct the lumen of the prostate channels, and may underlie some cases of BPH. Prostate cancer is one of the most common cancers affecting elderly men in developed countries and a major cause of death for older men (some specialists estimate of 3%). Regular rectal exams are recommended for older men to detect prostate cancer early. In 1993, the journal of the American Medical Association showed that there is a connection between vasectomy and an increased risk of prostate cancer. The reported investigation of 48000 and 29000 men who had vasectomies showed 66 percent and 56 percent higher rates of prostate cancer, respectively. The risk increases with age and the number of years since the vasectomy was performed. However, in March of that year, the National Institute of Child Health and Human Development, a conference cosponsored by the National Cancer Institute and others to review the available data and information about the link between prostate cancer and vasectomies. It was found that an association between the two was very weak at best, and even if a vasectomy at increased risk, the risk is relatively small. Recent scientific breakthroughs have the intention of using a Prostatic stent is a viable method of far-obstruction of the prostate. Stents devices are incorporated into the urethra to broaden and keep it open. Stents can temporarily or permanently, and is usually done by an outpatient basis under local or spinal anesthesia and usually takes about 30 minutes.
