Sperm Retrieval Treatment PESA / TESA

Sperm Retrieval Treatment

Complete evaluation of the malefactor in infertility is done. Medical or surgical treatment of absence or low sperm counts, by PESA / TESA.

Several per-cutaneous and open surgical procedures have been described to retrieve sperms:

  • In men with obstructive azoospermia, epididymal sperm can usually be retrieved by percutaneous epididymal sperm aspiration (PESA). If PESA fails then testicular sperm are obtained by needle aspiration biopsy (NAB).
  • In men with non-obstructive azoospermia, there will be no sperm in the epididymis and testicular sperm retrieval is required. Testicular sperm extraction (TESE) from open microsurgical biopsies is performed using the single seminiferous tubule (SST) or the micro-dissection TESE techniques.

How Long is Sperm retrieval Treatment?

The fluid obtained after the surgical retrieval is inspected immediately by embryologists under a microscope for surgical sperm content and motility. The procedure takes about 20-30 minutes.
