TESA / PESA

Percutaneous Epididymal Sperm Aspiration (PESA) and Testicular Sperm Aspiration (TESA) are surgical techniques employed to retrieve sperm. PESA involves the collection of sperm from the epididymis through the use of a fine needle and syringe. On the other hand, TESA involves the direct retrieval of sperm from the testicles. These methods are commonly employed for men diagnosed with azoospermia resulting from primary testicular conditions, which significantly reduce sperm production within the testes. In such cases, where epididymal sperm is usually absent, the retrieval of sperm directly from the testicles becomes necessary.
