FIGURE 1.

Ultrasound image of the normal male testicle during mini‐puberty using high‐frequency (12 MHz) linear probe. During this phase of life, the testes appear symmetrical, equal in size (approximately 0.5–1.5 mL), and homogeneous, but also more hypoechoic than adult testes. Note that the mediastinum appears evident and tendentially hyperechogenic
