In males the prostate gland which is part of male reproduction system, weighs few grams at birth and gradually increases in volume and size with age.
The cells of the prostate are under the influence and respond to action of hormones. As age advances, hormonal changes make their way into the constitution and modify the growth of prostate. One theory attempting to explain causes of Benign Enlargement of Prostate (BEP) is that as testosterone levels keep reducing and estrogen levels correspondingly increase in males as he ages, the increase in estrogen can trigger prostate enlargement.
