Does the prostate grow as part of the growth process during puberty or is it the same size always?

Grows with puberty: The prostate gland secretes a slightly alkaline fluid, milky or white in appearance, that usually makes up about half of the volume of the semen along with sperm and thus considered as part of the male reproductive system. Testosterone is needed for the normal growth of the prostate and during puberty levels of testosterone accelerate the growth of prostate to the adult size, about walnut size.
