Systematic scrotum ultrasound in male infertility: what to look for.

Ultrasound is a useful, cost-effective and minimally invasive tool that can be used in the workup of male infertility. Patient history, semen analysis and hormonal results often precede ultrasound examination as a part of the workup of male factor infertility. In our article, we advocate the added value of a systematic approach of the scrotal ultrasound. We propose a checklist for the complete analysis of testicular and paratesticular structures, useful in everyday practice for both clinicians and radiologists, highlighting what can be expected of and what should be found in the radiologist's report.
