The prostate is an accessory gland of the male reproductive system. The major function of the prostate is to create fluid for semen, which transports sperm throughout the male orgasm. This is the fluid that carries sperm.

The prostate gland changes size as a man ages. The first change comes in the early years of puberty where the prostate doubles in size. Then again in a man’s mid-twenties, the prostate begins to grow again, slower this time but continuous throughout the rest of his life.

Age changes of the prostate:

At birth –

The prostate is small in size and is made up mainly of stroma with a simple duct system.

At childhood –

Between 9 to 14 years the duct system becomes elaborated by the formation of side buds.

At puberty –

Due to the release of the male sex hormones the side 1 of the prostate becomes double its prepubertal size.

Between 20 to 30 years –

Marked proliferation of the glandular elements with the unfolding of the glandular epithelium into the lumen of the follicles.

Between 30 to 45 years –

The size remains constant.

After 45 to 50 years

The prostate is either enlarged or reduced in size. These changes are progressive till death.
