Abstract
A cross sectional study was conducted on 1000 school children between the ages of 8–16 years, to find out the normal testicular volume. At 8 years the testicular volume averaged 1.4 ml. This increased at the rate of 0.5 ml per year, till it reached 2.9 ml at the age of 11 years. A spurt in testicular growth (increment of 1.6 ml) was recorded between 11 and 12 years. This accelerated growth continued at a rate of about 2.5 ml to 4.0 ml/year, so as to attain a mean testicular volume of 15.6 ml by 16 years of age. It is suggested that a testicular size upto 2.0 ml may be considered infantile as this size correlated with prepubertal stages G1 and PH1 and an increase in the size beyond this may be regarded as the earliest evidence of puberty.
