What is a Prader orchidometer?
The most widely used orchidometer is the Prader orchidometer introduced in 1966. This type of orchidometer, a graded series of ellipsoid beads on a string, is used for testicular volume measurement, which is a useful index of puberty in male in order to evaluate male growth and development.
How do you use an orchidometer?
To use an orchidometer, doctors gently pull the testicle to the bottom of a boy’s scrotum and use touch and sight to find the bead that matches it in volume.
What is normal testicular volume?
Normal adult testes are ovoid and measure approximately 3 cm (AP) x 2-4 cm (TR) x 3-5 cm (length), with a volume of 12.5-19 mL 2. However, the size of the testes decreases with age. From the mediastinum testis, several radiating septa extend into the testis forming 250-400 lobules.
What does an Orchidometer measure?
An orchidometer is a medical instrument that can be used to accurately measure volume and determine the size of the testicle. The cutout sizes are compared with the testicle of the patient using the volume that matches most closely in size.
How do you calculate testicular volume?
The ultrasound measurements of testicular volume were calculated using three formulas: length (L) x width (W) x height (H) x 0.52, L x W2 x 0.52, and L x W x H x 0.71. The actual testicular volumes were determined by water displacement of the surgical specimen.
How much is one testicle on the black market?
On the black market typically a pair of healthy testicles will sell for $50,000. However just selling the left nut will bring in $35,000 while just selling the right nut is only valued at $9,000. Buyers on the black market are looking for increased blood flow, size, testosterone production, and sperm production.
How do you measure testicular volume on ultrasound?
Currently, most ultrasound machines indicate the testicular volume automatically, using the formula length × width × height × 0.52 (formula 1). We recommend to use the formula length × width × height × 0.71 as the accepted norm instead and to incorporate it into the ultrasound software.
What are the grades of varicocele?
There are three grades of varicocele: Grade I: able to be felt only when the patient is straining (valsalva maneuver) Grade II: able to be felt at rest, but not visible. Grade III: clearly visible on exam.
How do you measure testicle width?
The provider measures the width of the testis in the scrotum, by smoothing the scrotal skin around the testis, avoiding compression, and using the ruler. When subtracted by the scrotal skin (ss), this measurement matches or should match the width obtained by US.
What happens if you stop ejaculating?
Unejaculated sperm is not harmful to the body and does not build up. The body reabsorbs sperm that does not leave through ejaculation. This has no side effects on sex drive or fertility. However, there may be possible side effects in people who delay or avoid ejaculating when sexually aroused.
What can a Prader orchidometer be used for?

How big are pubertal size Prader Orchidometers?
Pre-pubertal sizes are 1-3 ml in yellow, pubertal sizes are considered 4 ml in orange and up and adult sizes are 12-25 ml in red. Doctors sometimes informally refer to them as “Prader’s balls”, “the medical worry beads”, or the “endocrine rosary.”
How big are Prader’s balls for an adult?
In the absence of varicoceles, the right and left testes are approximately equal in size. Pre-pubertal sizes are 1-3 ml in yellow, pubertal sizes are considered 4 ml in orange and up and adult sizes are 12-25 ml in red. Doctors sometimes informally refer to them as “Prader’s balls”, “the medical worry beads”, or the “endocrine rosary.”
Why are Prader balls called the medical worry beads?
Doctors sometimes informally refer to them as “Prader’s balls”, “the medical worry beads”, or the “endocrine rosary.” To provide a patient with a symmetrical, natural appearance in the scrotum, it is important to closely match the size of the existing testes.
