Testicular mapping
Also known as Sperm mapping or a Sperm Fine Needle Aspiration
A non-surgical alternative to a testes biopsy used to map out the location of sperm in the testes
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.
