What is TESA?
Testicular sperm aspiration (TESA: surgical sperm retrieval technique) involves placing a needle attached to a syringe through the skin of the scrotum and simply sucking out the fluid inside the testicle.
When to go for TESA?
- Testicular sperm extraction is indicated for below patients:
- There is a blockage in the epididymis very near the testis (either from prior surgery, infection or from birth)
- Blockage within the ducts of the testes (efferent ductules).
- Poor sperm production, in which so few sperm are produced that they cannot reach the ejaculate.
