Enquiries & Appointments

What is testicular mapping?

Testicular mapping is a recent development for azoospermic men, pioneered by Dr Paul Turek in California. It involves a simple minimally-invasive procedure performed under either local or general anaesthesia to map out the potential location of sperm in the testis.

This allows us to determine if a man is likely to be candidate for a successful subsequent sperm retrieval.

The benefits of this two-step process are to guide urologists directly to areas of sperm production (with some studies suggesting an increase to more than 90% success) and to minimise potential damage to the testis from multiple failed biopsies. Furthermore, a negative map may help couples decide on alternative options such as the use of donor sperm

Urologists can now offer this procedure if deemed appropriate.
