Mystery Object, #8

What is this object? The answer is below in extended.


It's a Prader Orchidometer. As described by wikipedia, this is "a medical instrument used to measure the volume of the testicles." The one above is available for purchase on Amazon for $85.

More info from wikipedia:

The orchidometer was introduced in 1966 by Swiss pediatric 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 millilitres. Doctors sometimes informally refer to them as "Prader's balls", "the medical worry beads", or the "endocrine rosary."

The beads are compared with the testicles of the patient, and the volume is read off the bead which matches most closely in size. Prepubertal sizes are 1–3 ml, pubertal sizes are considered 4 ml and up and adult sizes are 12–25 ml....

Stephen Shalet, a leading endocrinologist who works for the Christie Hospital in Manchester, is reported to have told The Observer, "Every endocrinologist should have an orchidometer. It's his stethoscope."

I knew this one immediately. The device made an appearance in some medical drama many years ago. It was used in a prank on a new student, female of course.

I thought they were for checking dimensions as you're turning Russian nesting dolls.

I thought it was a gauge for bird eggs.
