Sperm recovery thecniques

what does it consist of?

In patients with certain types of azoospermia, or who have previously undergone a vasectomy, a sufficient amount of sperm cannot be found in a semen sample to perform an assisted reproduction treatment. In these cases, sperm recovery techniques allow to recover a sperm sample directly from the testicles.

Techniques

EPIDIDYMAL
eXTRACTION
  • Pesa: Percutaneous Epididymal Sperm Aspiration. A needle is inserted under the skin of the scrotum to reach the epididymis and remove the sperm.
  • Mesa: Microsurgical Epididymal Sperm Aspiration. A small incision, of one or two centimetres, is performed in the scrotal tissue to facilitate access to the epididymis. This method allows recovery of a greater volume of motile sperm.
TESTICULAR
EXTRACTION
  • Tesa: Testicular sperm aspiration. Fluid containing the sperm is aspirated from the testes using a needle.
  • Tese: Testicular sperm extraction. If the previous techniques have been ineffective, a biopsy of the testicle will be needed. To do this, an incision will be made in the scrotum and a portion of testicular tissue will be removed, which will contain the sperm.
