The prostate is a gland set between the bladder and the penis in human males. The prostate is about the size of a walnut, or 1. During ejaculation, the prostate will expel an alkaline seminal fluid into the urethra. The alkaline nature of semen counters the acidic environment of the vagina. This protects sperm, and prolongs the time in which sperm can be motile in the vaginal tract. The prostate gland also relies on muscle to help eject the sperm. Illustrated in the picture is the prostate gland and neighboring organs. The prostate is the largest accessory gland in males. It is found inferior to the neck of the bladder, and above the urethral sphincter as pictured in the illustration. Moreover, the prostate lies in front of the rectum, making it easy for physicians to conduct digital rectal exams DRE to inspect the health of the gland. Furthermore, the prostate gland can be divided into four anatomical lobes. But a more significant delineation is a histological parsing into zones. The central zone is the area that surrounds the ejaculation ducts. It derives from the Wolffian duct in human embryos. The transitional zone is the area near the center that surrounds the urethra. It derives from the urogenetical sinus. The peripheral zone forms the body of the prostate gland. This area is located toward the back, and derives from the urogenital sinus. The prostate gland is notably vascular and well-innervated. The arterial supply, or oxygen rich blood, of the prostate comes from the prostatic arteries. In contrast, oxygen-depleted blood drains into the prostatic venous plexus and enters the iliac veins of the pelvis. The innervation of the prostate gland is a little simpler. The prostate gland is innervated by the inferior hypogastric nerve plexus. A plexus is more or less a...

The prostate is a walnut-sized gland located between the bladder and the penis. The prostate is just in front of the rectum. The urethra runs through the center of the prostate, from the bladder to the penis, letting urine flow out of the body. The prostate secretes fluid that nourishes and protects sperm. The vasa deferentia singular: The seminal vesicles contribute fluid to semen during ejaculation. Prev Next Side View of the Prostate The prostate is a walnut-sized gland located between the bladder and the penis. Inflammation of the prostate, sometimes caused by infection. In some cases, it is treated with antibiotics. Called benign prostatic hypertrophy or BPH, prostate growth affects virtually all men over Symptoms of difficult urination tend to increase with age. Medicines or surgery can treat BPH. Surgery, radiation, hormone therapy, and chemotherapy can be used to treat prostate cancer. Some men choose to delay treatment, which is called watchful waiting. A doctor inserts a lubricated, gloved finger into the rectum and feels the prostate. A DRE can sometimes detect an enlarged prostate, lumps or nodules of prostate cancer, or tenderness from prostatitis. The prostate makes a protein called PSA, which can be measured by a blood test. Prostate ultrasound transrectal ultrasound: An ultrasound probe is inserted into the rectum, bringing it close to the prostate. Ultrasound is often done with a biopsy to test for prostate cancer. A needle is inserted into the prostate to take tissue out to check for prostate cancer. This is usually done through the rectum. Alpha-blockers relax the muscles around the urethra in men with symptoms from an enlarged prostate. Urine then flows more freely. These medications reduce the level of a certain form of testosterone DHT. The prostate shrinks when less DHT is present, improving urine flow. Surgery for...

The prostatic fluid is expelled in the first ejaculate fractions, together with most of the spermatozoa. In comparison with the few spermatozoa expelled together with mainly seminal vesicular fluid, those expelled in prostatic fluid have better motility , longer survival and better protection of the genetic material. The prostate also contains some smooth muscles that help expel semen during ejaculation. The classical description of a healthy human male prostate portrays it as slightly larger than a walnut. The secretory epithelium is mainly pseudostratified, comprising tall columnar cells and basal cells which are supported by a fibroelastic stroma - containing randomly oriented smooth-muscle bundles - that's continuous with the bladder. The epithelium is highly variable and areas of low cuboidal or squamous epithelium are also present, with transitional epithelium in the distal regions of the longer ducts. One can sub-divide the prostate in two ways: The "zone" classification is more often used in pathology. McNeal first proposed the idea of "zones" in McNeal found that the relatively homogeneous cut surface of an adult prostate in no way resembled "lobes" and thus led to the description of "zones". The prostate gland has four distinct glandular regions, two of which arise from different segments of the prostatic urethra:. The "lobe" classification is more often used in anatomy. The prostate is incompletely divided into five lobes:. The prostatic part of the urethra develops from the pelvic middle part of the urogenital sinus endodermal origin. Endodermal outgrowths arise from the prostatic part of the urethra and grow into the surrounding mesenchyme. The glandular epithelium of the prostate differentiates from these endodermal cells, and the associated mesenchyme differentiates into the dense stroma and the smooth muscle of the prostate. Condensation of mesenchyme , urethra and Wolffian ducts gives rise to the adult prostate gland, a...
