Why choose testicular mapping?
For men whose fertility problem lies not in a blockage preventing the sperm from reaching the ejaculate, but in sperm production, testicular mapping can be a more effective – and considerably less invasive – diagnostic tool than the alternative, a biopsy. This is because, even in men with no sperm in the ejaculate, there may still be pockets of sperm within the testicular tissue. These pockets are often missed in a biopsy, which looks only at one section of tissue at a time. Although it is possible to perform more than one biopsy at a time, every extra biopsy adds further risk to the patient.
Once your testicular mapping results have come in, if sperm has been located, then you can decide on a sperm retrieval method, such as TESA, and this can then be perfectly tailored, as the surgeon knows exactly which areas of the testicles contain sperm.
Although it is important to remember that testicular mapping in itself is a diagnostic procedure, rather than a fertility treatment, it can help to make future sperm retrieval methods less time-consuming, less invasive and even less stressful as you can rest assured that there is sperm to be retrieved. Once the sperm has been removed, it can then be used for future IVF/ICSI treatment cycles and the possibility of conceiving a child could become a reality.
