The prostate is a small, walnut-shaped gland that is an essential part of the male reproductive system. Understanding its normal size is important for diagnosing age-related health issues.
Prostate cancer is one of the most common cancers in men globally. A blood test called PSA (Prostate-Specific Antigen) is used to screen for prostate issues.
In a healthy young adult male, the normal dimensions of the prostate gland are approximately:
(Note: Prostate size is usually measured via ultrasound and reported in 'cc' or 'grams'. 1 cc is roughly equivalent to 1 gram).
The primary function of the prostate gland is to produce a white, alkaline fluid that makes up about 30% of the semen volume. This fluid nourishes and protects sperm, helping them survive the acidic environment of the female reproductive tract.
As men age (usually after 50), the prostate naturally begins to grow. This non-cancerous growth is called Benign Prostatic Hyperplasia (BPH).
Because the prostate surrounds the urethra, an enlarged prostate squeezes the tube, causing frequent, difficult, or incomplete urination.
The prostate often goes through a second growth phase in a man's mid-20s, but symptomatic enlargement (BPH) usually begins to affect men in their 50s and 60s.
