Testicular Mapping


Testicular Mapping is a minimally invasive procedure during which a fine needle is placed in different areas of the testes to obtain small samples of testicular fluid. The aspirate is fixed on a slide and checked for sperm following the procedure. If sperm is found, a future sperm retrieval will be scheduled during an IVF-ICSI Cycle and will be carried out from the sites where sperm was found during the original mapping. IVF Michigan Fertility Center also offers  Advanced Testicular Mapping, a technique that allows for sperm to be analyzed during the procedure and frozen for future use, eliminating the need to perform future aspirations once sperm is located. With over 60 years of collective experience and locations in Bloomfield Hills, Ann Arbor, Dearborn, Saginaw and Toledo, OH, the physicians of IVF Michigan Fertility Center are available to help couples throughout the Midwest and abroad.

The Advantages and Disadvantages of Testicular Mapping:  

  • Advantages: Testicular mapping is useful because it helps predict the presence of sperm before the start of the wife’s stimulation. It also identifies favorable areas for finding sperm. 
  • Disadvantages: On the other hand, the disadvantages are that a second procedure is required to retrieve sperm at the time of the IVF procedure and sometimes sperm is not be found during this second procedure. To bypass these disadvantages, Fakih IVF also offers Advanced Testicular Mapping.  

Advanced Testicular Mapping 

Advanced Testicular Mapping is a technique during which a fine needle is placed in different areas of the testes, aspirating small samples of testicular fluid that is immediately analyzed for viable sperm. If viable sperm is found, it is frozen and used in a future IVF-ICSI cycle. In the advanced technique of testicular mapping, there are three modifications to the testicular mapping technique described above: 

  1. A larger needle is used, allowing more tissue and sperm to be recovered. This makes the process more efficient in finding sperm.
  2. The IVF lab checks the aspirate immediately, allowing live sperm to be identified. This eliminates the need to perform future aspirations once sperm is found.
  3. Sperm is frozen for future use and a second procedure is avoided.
