Diabetes Headquarters sell the Prader Orchidometer-B .

The orchidometer (or orchiometer) is a medical instrument used to measure the volume of the testicles.


The orchidometer was introduced in 1966 by Swiss paediatric endocrinologist Andrea Prader of the University of Zurich.

It consists of a string of twelve numbered wooden or plastic beads of increasing size from about 1 to 25 millilitre’s.

Doctors sometimes informally refer to them as "Prader's balls", "the medical worry beads", or the "endocrine rosary".


The cutout sizes of the Prader Orchidometer are compared with the testicle of the patient using the volume that matches most closely in size.

The Prader Orchidometer consists of 12 pieces of beads with number.

Colour coded based upon Tanner staging to assist those clinicians who are in training.

The number is clearly visible and organise significantly according to the different stages of growth.


The Prader Orchidometer is made by high quality beech. It won’t be shrunk and twisted. It can last for your entire career.

The Endocrine Rosary will come with a small carrying pouch for protection & storage. The Endocrine Rosary string on a sturdy string for easy sliding.
