What is the normal size in millimeters of prostate at the age of 70?

According to a 2011 study published in Springer, the mean total prostate volume for men aged 50–80 years continuously increases with age. This makes answering "What is the normal size in millimeters of prostate at the age of 70?" more nuanced than providing a single number, as average prostate dimensions change with age and vary between individuals. At 70, a prostate is generally larger than in younger adulthood, and millimeters are one way doctors can measure its size through imaging.
