Outcome measures
Primary outcome
Normative values for testicular volume measured by ultrasonography in boys from
0 to 18 years old.
Secondary outcome
n.v.t.
Background summary
Until now, measurement of testicular volume was mainly performed by using a
Prader orchidometer. Recent studies showed that testicular volume measured by
ultrasonography is considered to be the best method. However, there are no
normative values of the size of the testis measured by ultrasonography in
childhood, through puberty till adulthood.
Study objective
The purpose of the study is to establish normative values of the size of the
testis measured by ultrasonography in childhood, through puberty till
adulthood. (0-18 years)
Study design
The testicular volume of both testes (from boys whose ages ranges from 0-18
years) will be determined using a Prader orchidometer and by ultrasonography.
The results will be noted on an apart form and the normative values for each
age-group (from 0-18 years) will be established.
Study burden and risks
The risks associated with participation are minimal.
