Wooden Prader Orchidometer, Prader Balls, Endocrine Rosary for Endocrinologist and Pediatrician to Measuring Testis Scale Vertical

I got this orchidometer for my office. As a pediatrician this tool becomes very helpful for diagnosis and documentation. The material used is wooden and is arranged in ascending order with measurement. The sizes are accurate. The beads are in well padded storage box. This is a good tool for education as well. The box however does not comes with any chart for medical students to follow like these sizes falls in this tanner and this is the age group. Such chart would be very helpful to teach along with this orchidometer.

This orchidometer is made well with lightweight wooden beads that are coated with a smooth polished paint. The different colors reflect the different category of sizes with yellow being prepubertal, orange pubertal, and adult in red. The numbers are also easy to read with a large font. They are all strung on a thin but sturdy red string. On a couple of the beads there were some minor dent like deformations but overall work to measure accurately. The zippered hard shell case has a nice soft but dense foam that looks like it would keep them in good condition when traveling with them.
