Testicular Measurement Assessment
A testicle measuring 1.4 cm in width, 4 cm in length, and 2 cm in height represents a calculation error or measurement technique problem, as these dimensions are anatomically implausible and inconsistent with normal testicular proportions.
Why These Measurements Are Likely Incorrect
The reported dimensions violate basic testicular anatomy in several ways:
Normal testicular proportions dictate that height should be approximately 50-60% of length 1. With a 4 cm length, the expected height would be 2.0-2.5 cm, which matches your reported 2 cm height 1.
However, the width of 1.4 cm is anatomically impossible when paired with a 4 cm length and 2 cm height. The width (shortest axis) should be similar to or slightly less than the height, not dramatically smaller 2.
Proper caliper placement is critical for accurate measurement 2. The caliper should be movable over the testis without squeezing it, and incorrect placement can significantly underestimate volume 2.
Most Likely Explanation
The width measurement of 1.4 cm was almost certainly obtained with incorrect caliper placement, likely squeezing the testis or measuring at an oblique angle rather than the true shortest axis 2. The length (4 cm) and height (2 cm) measurements appear more plausible and consistent with each other.
Clinical Significance of Correct Measurements
If we assume the length (4 cm) and height (2 cm) are accurate, and estimate the width should be approximately 1.8-2.0 cm based on normal proportions:
This would yield a testicular volume of approximately 8-10 mL, which is definitively atrophic 1, 3.
Testicular volumes <12 mL warrant comprehensive evaluation, particularly in men under 40 years, as they carry a 34% risk of intratubular germ cell neoplasia in the contralateral testis if associated with testicular cancer 1, 3.
A single testicle of 7-9 mL suggests significant spermatogenic dysfunction, especially if bilateral, and requires evaluation for non-obstructive azoospermia and genetic abnormalities 1.
Recommended Action
Request repeat measurement by an experienced examiner or ultrasound evaluation 2. Scrotal ultrasound provides more accurate volume assessment than manual measurement, particularly when physical examination is challenging due to factors like thickened scrotal skin, large epididymis relative to testis, or small testicular size 2.
