Prostate is an important Gland in males and it is also found in most mammals.
The Prostate the size of a walnut and it is located just below the Bladder.
The prostate gland helps in the production of semen, a fluid that helps transport and nourish sperm. It is considered an exocrine gland of the Male Reproduction System.
Women do not have a prostate, however, the Skene’s gland in women is the homologous organ.
– The primary function of the prostate is semen production, a milky or white and alkaline substance.
– The prostate contributes to approximately 30% of the semen production.
– Another large portion comes from the seminal vesicles and the spermatozoa.
– Control of the prostate is done through a hormones, androgen or male hormones, or often referred to as testosterone
– It surrounds the urethra just below the bladder.
– It can be felt during a rectal exam.
– The prostate can be divided in two ways: by Zone or by Lobe
Different Zones or Tissues:
1.) Peripheral Zone
– Posterior aspect of the prostate
– Surrounds the distal Uretha
– Approximately 70% of Prostate Cancers start from this Zone
2.) Central Zone
– Surrounds the ejaculatory ducts
– Approximately 3% of Prostate Cancers
– If prostate cancer arises in this area the cancer is often more aggressive and can invade the seminal vesicles.
3.) Transition Zone
4.) Anterior Fibromuscular Zone
– Is usually without any glandular components
– Only has muscle and fibrous tissue
1.) Anterior lobe or Isthmus – Corresponds mostly with the Transitional Zone
2.) Posterior lobe – Corresponds mostly with the Peripheral Zone
3.) Lateral lobes – Spans all Zones
4.) Median lobes – Corresponds mostly with the Central Zone
