The orchidometer consists of 16 punched-out elliptical rings with graded volumes, 1-30 mL (1 to 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 and 26 mL).
The punched-out orchidometer is useful for serial measurement when the absolute volume is not important, for example, in the follow of the development of individual testicular volume in children after orchidopexy [12].
For ipsilateral testis after torsion, we must be aware that orchidometer overestimates the testicular volume because of the thickened scrotal connective tissues and that USG is required during the follow-up period to detect the atrophy.

The testicular volumes of 136 testicles were measured using the Prader orchidometer and scrotal ultrasonography.
