We assessed boys' stages of genital development (G1-G5) and pubic hair development (PH1-PH5) visually and measured testicular volume (TV) using orchidometer
beads as comparisons.
Testicular volume was determined with a Prader orchidometer
as follows: <4 ml for stage G1, 4-8 ml for stage G2, >8-15 ml for stage G3, >15-20 ml for stage G4, and >20-25 ml for stage G5.
Testicular volume was evaluated using the Prader orchidometer
in boys and recorded.
However, these evaluations are done with a caliber and/or orchidometer
, which are not quite accurate, compared to testicular ultrasonography.
Testicular size and volume can be estimated in the office with an orchidometer
. Some studies have shown accurate correlation between testicular volume measurements from a Prader orchidometer
Macroorchidism was diagnosed when testicular volume measured with a Prader orchidometer
was greater than the 95th percentile of the modified standard scale  (age [less than or equal to] 8 years, 1-2 ml: score = 0, 3 ml: score = 1, >3ml: score = 2 or age >8 years, 95th percentile -2 ml: score = 0, 95th percentile [+ or -] 1 ml: score = 1, 95th percentile +2 ml; score = 2).
The penile length was normal but testicular volume was decreased (approximately 5 [cm.sup.3] as determined using the Prader orchidometer
Tenders are invited for Supply of Praders orchidometer
.Laparoscopic reusable & autoclavable retracting device like fan retractor -5mm 31 cm long.
Using an orchidometer
, the right testes measured 15 ml and the left testes 8 ml, 53% smaller than the right testes.
Testicular volume: comparison of orchidometer
and US measurements in dogs.
An objective determination of testicular size can be determined by a number of methods, including calipers, orchidometer
beads, and ultrasound (Paduch & Skoog, 2004).
Let's put it this way: when the topic of an orchidometer
(look it up) came up in regard to Bonds', um, physical capabilities, there's a lot more you can do from the courtroom with a blog than what you can get into a family newspaper.
