Male genital tract imaging

Scrotal Ultrasound and duplex

This allows accurate visualisation of the testes to determine their size, blood flow, diagnose varicocele, obstruction and testis cancer.

Any man with low sperm count should have a scrotal scan because the risk of Testis cancer is 0.5–1% in infertile men Vs 0.001%- 0.01% in the general population.

In men with a history of undescended testes the risk is even higher (2–6%) even if they were brought down during childhood.

Trans-rectal Ultrasonography (TRUS)

TRUS is needed if your doctor thinks that you have a blockage of the seminal ducts which run inside the prostate. This condition is called ejaculatory duct obstruction (EDO) and is a correctable cause of male infertility.
