The investigation of male infertility is assuming greater importance, with male factors implicated as a causal factor in up to half of infertile couples.
Following routine history, examination and blood tests, imaging is frequently utilised in order to assess the scrotal contents for testicular volume and morphology. Additionally, this may give indirect evidence of the presence of possible reversible pathology in the form of obstructive azoospermia. Further imaging in the form of transrectal ultrasound and MRI is then often able to categorise the level of obstruction and facilitate treatment planning without resort to more invasive imaging such as vasography. Ultrasound guidance of therapy such as sperm or cyst aspiration and vasal cannulation may also be performed. This article reviews the imaging modalities used in the investigation of male infertility, and illustrates normal and abnormal findings that may be demonstrated.
