What is Surgical Sperm Retrieval?
Surgical Sperm Retrieval is commonly used to extract sperm from the testes for use in ICSI. It is necessary when a man is unable to produce sperm in his ejaculate, has had a failed vasectomy reversal, or has absent vas deferens – the duct that carries sperm from the epididymis to the penis.Sperm can be surgically recovered in two ways:
- Percutaneous Epididymal Sperm Aspiration (PESA)
- Testicular Sperm Aspiration (TESA)
What is involved during PESA and TESA?
During PESA, a needle is inserted into the epididymis and sperm is withdrawn. However, if sperm cannot be found in the epididymis, TESA is used to extract sperm from testicular tissue, and the needle is inserted directly into the testis. Following these procedures patients may experience discomfort or pain and may have some localised swelling. However, patients who undergo PESA typically may return to work the following day.
Treatment using ICSI with PESA has an average of 25% success rate per cycle, depending on the female partner’s age.
