 PSA is a protein which is produced by the cancerous and also by the non cancerous in the prostate.Use the  prostate size calculator to find the size of your prostate.

What is prostate volume?

Prostate volume is one of the important  indicators that you are carrying the prostatitis or not. The prostate gland produces and contains the fluid in which the semen remains alive in the acidic environment of the vagina. Prostatic fluid is slightly alkaline milky or white in appearance.

People having prostatitis usually feel irritation during the urination and they feel pain during the urination. Men with prolonged prostatitis may lose vitality due to a lack of alkaline fluid.

How to measure prostate size?

There are three major approaches to measuring the prostate volume:

  • Transrectal ultrasonography (TRUS)
  •  Prostate ellipse volume calculation
  •  An ellipsoid volume measurement technique

Prolate ellipse volume calculation is the most precise and practical for clinical applications. The ellipsoid volume calculator provides accurate information regarding the size of the prostate when entering the length, width, and height of the prostate.

Prostate volume formula for ellipse=height (cm) × length (cm) × width (cm) × π/6

The cross-sectional area of the prostate represents the prostate glands are more bullet-shaped compared to ellipsoids. The formula for the bullet shape prostate gland is:

Bullet volume of prostate = height (cm) × length (cm) × width (cm) × 5π/24.

The prostate volume calculator swiftly finds prostate size measurement by the Prostate volume formula for ellipse and the Bullet volume of the prostate.

Prostate-Specific Antigen (PSA):

The is an enzyme produced by the prostate gland and its concentration is usually increased prostate cancer. The prostate volume calculation does require that we present the length, width, and height of the prostate size. The increased prostate size indicates a person can be a victim of prostate cancer and it may indicate prostatitis or BPH (Benign Prostatic Hyperplasia). The highest normal value of the Prostate-Specific Antigen (PSA) is 4 ng/ml (nanogram per milliliter)

Why do we use Prostate-Specific Antigen (PSA)?

The Prostate-Specific Antigen (PSA) density is a parameter to find, are you a victim of prostate cancer or  BPH(Benign Prostatic Hyperplasia). If you find that the PSA is increased, you may need to attend the doctor’s.

Working of the Prostate Volume Calculator:

The prostate volume calculation provides us with important information about the size of the prostate gals and the PSA density.


  • Enter the length, width, and height of the prostate gland
  • The PSA  is optional to enter
  • Hit the calculate button


The prostate volume measurement of PSA is important to find whether we can be victims of prostate cancer or not:

  • The  PSA density in the blood is displayed


What is considered a normal prostate volume?

The normal size of the prostate gland is 3 × 3 × 5 cm or 25 ml. The prostate size calculator is needed to find the accurate size of the prostate gland.

Does the prostate size remain the same?

What prostate size is considered to be large in ML?

The 80 ML or 80 cm^3 sizes of the prostate gland are considered to be enlarged. We can figure out the enlarged prostate by the prostate volume calculator.  

How does the urologist accurately measure the size of the prostate?

The prostate volume is measured by the Urologist through the rectal examination, TRUS computed tomography, and also by the prostate volume calculation. A  prostate gland volume calculator is the most simple method to find the size of the prostate.

What are the causes of prostate enlargement? 

The enlargement of the prostate gland is unknown but it is believed that growing age can be a cause of an enlarged prostate gland. The hormonal balance is disturbed due to growing age. The prostate volume calculator can spot the enlarged prostate.


The prostate glands are important to release a secretion that actually protects the siemens in the acidic vaginal environment. If the prostate glands aren’t working properly, then you may face endangered vitality in men due to a lack of alkaline liquid. Patients may face difficulty in Urination, and you need to use the prostate volume calculator to find the size and PSA level in your blood.
