Sperm retrieval techniques

When a man has no sperm in his ejaculate, yet testing and examination suggests that there may be sperm in the testes, then the procedure of testicular biopsy or Percutaneous Epididymal Sperm Aspiration (PESA) may be of help to the couple.

Testicular Biopsy

The procedure of testicular biopsy is performed with a fine needle. This involves placing a fine needle into the testes and withdrawing some of the tubules from within the testes which contain live sperm. The procedure is usually performed under local anaesthesia.
