PSA concentration in men with a prostate volume <25 cc also showed a continuous increase with aging, starting at 0.8 in the youngest and ending at 1.9 ng/ml in the oldest age group.
The prostate is a walnut-sized organ that is part of the male reproductive system. It typically weighs between 20-40 grams with an average size of 3 x 4 x 2 cm. The gland is enlarged based on these measurements. Enlarged prostates differ in size.
You should talk with your doctor about a prostate biopsy because, sometimes, the Benign Prostate Hyperplasia (BPH) may be transformed in prostate cancer . In this case, doctors may recommend just watching the prostate or doing non-surgical treatments. When the prostate becomes more enlarged over time, it might press against the urethra and block urine flow (usually around age 50). The prostate normally measures 3 cm in length (height), 4 cm in width (transverse), and 2 cm in depth (anteroposterior dimension).It remains relatively stable in size until the age of 50 when increasing weight of the gland is observed. Patients also may try supplements like saw palmetto to help their symptoms.For patients who have moderate or severe symptoms that have failed medical therapy from very enlarged prostates, the optimal treatment is often surgery.

The matrix of the gland is heterogeneous The bladder wall is thickened anteriorly.Image Courtesy Ashley Davidoff MD Copyright 2010 76771.8s Leaf Group Ltd. in the axial plane. But after 50, a significant percentage of men have a condition known as benign prostatic hypertrophy, enlargement of the gland, due to various factors. In a study conducted by Stephen Freedland and colleagues and published in the February 2006 issue of "The Journal of Urology," mildly obese men were found to have prostatic weights of 40 g -- roughly double its normal size. Note that BPH is a misnomer because the enlargement is due to hyperplasia and not hypertrophy.Image (c) illustrates the enlarged transitional zone which is where the hyperplasia of BPH takes place.Image Courtesy Ashley Davidoff MD Copyright 2010 25078c04bL01.8sThe CTscan is from a patient with an enlarged prostate. Bottom line: The DRE estimate of prostate size is only accurate for round small prostate.
A normal prostate gland weighs about 20g-30g in a 30 year old male. This calculation reveals a volume of 25ccs which is normal.The 70 year old male shows an enlarged prostate 7.2cms in A-P by 6.1cms. The prostate remains very small until puberty.

The size of the prostate varies with age. Adult males have a normal prostate volume which ranges from 15 cubic centimeters (0.9 cubic inches) to 30 cubic centimeters (1.8 cubic inches). By the age of 80, the average prostatic weight is 35-45g.A simple prorated ellipsoid formula is commonly used to calculate prostate volume: (anterior-posterior diameter) x (transverse diameter) x (superior-inferior diameter) x Π/6 (approximately 0.52) is accurate and reproducible.From a practical point of view in imaging the gland is usually enlarged if the transverse dimension is greater than 4cms.The volume of this gland is calculated by the formula using a simple prorated ellipsoid formula. The size can be estimated on digital rectal exam or prostate imaging like an ultrasound. The peripheral zone is suggested by a hypodense posterior region (maroon arrow) Image Courtesy Ashley Davidoff MD Copyright 2010 24842.81sThe CTscan reconstructed in the sagittal plane is from a patient with an enlarged prostate. If you find yourself waking up more at night and experiencing any changes in the way you urinate, such as a weaker stream or increased frequency it's a good time to tell your doctor.

If your prostate size normal for your age? However, size is not the only factor used to choose a treatment.When doctors evaluate the prostate, symptoms are just as important as size.
For patients weighing 11 kg, 28.9 kg (the mean population body weight), and 70 kg, the typical plasma half-life (t½) is 7.4 hours, 10.6 hours, and 14.8 hours, respectively. Since the prostate gland has 4 major zones and we have accounted for the peripheral zone (pz), three other zones are present. A normal prostate gland weighs about 20g-30g in a 30 year old male. in the axial plane. The anterior aspect of the gland protrudes with two symmetrical homogeneous components likely representing an enlarged transitional zone and prostate hyperplasia though by the nature of the disease the combination of cancer and BPH commonly coexist.
