The provided data indicates that a "normal" prostate size is generally considered to be approximately 4cm wide, 3cm long, and 2cm in anterior-posterior diameter, with a weight of around 20g after age 20. However, prostate size does change with age.
Here's a breakdown:
- At birth: The prostate is very small, about the size of a pea.
- Up to age 20: The prostate grows steadily, reaching a weight of 15-20g.
- Ages 30-45: Prostate size typically remains stable at around 20g.
- After age 45: The prostate can often enlarge, a condition known as Benign Prostatic Hyperplasia (BPH). While the reference doesn't specify sizes for these later stages, BPH is common, and the prostate can significantly increase in size, leading to urinary symptoms. The degree of enlargement considered 'normal' at these older ages is subjective and depends on the absence or severity of symptoms.
It is crucial to note that "normal" can vary, and size alone isn't the only factor. The presence or absence of symptoms is important. Even if a prostate is larger than the measurements above, it may not be considered problematic if it isn't causing any issues.
