TESA = Testicular Sperm Aspiration
Even though some men do not have live sperm cells in their sperm sample, they may well have live sperm cells in their testicles.
TESA is a method that involves extracting sperm from the testicles.
Therefore, this makes is a useful method for men who have had a vasectomy.
During the TESA procedure, a small sample of tissue is taken using a thin cannula. The tissue sample is examined immediately in the laboratory. Sometimes a single sample is not enough and another attempt is made or sperm cells are extracted from the other testicle.
A precondition for having TESA is that the man has been investigated and that a real chance of extracting sperm cells has been found.
However, there is a risk of finding no live sperm cells that can be used. If this is the case, the option of using donor sperm can be considered.
TESA always involves the use of ICSI.
The cost of TESA will be in addition to the cost of IVF.
