Surgical Sperm Retrieval
TESA is a **minimally invasive surgical procedure** used to retrieve sperm directly from the testicle. This is essential for men with zero sperm count (Azoospermia) or blockage, allowing them to use their own genetic material for IVF/ICSI.
A blockage (e.g., prior vasectomy or infection) prevents sperm release.
Sperm production is very low, but can still be found directly in the testicular tissue.
The procedure is performed under light sedation. Retrieved sperm is immediately transferred to our lab for ICSI, ensuring only the highest quality, viable sperm is used for fertilization.
Sperm retrieved via TESA are typically few in number and non-motile. Therefore, TESA is always paired with **ICSI** to ensure effective fertilization of the eggs retrieved during the IVF cycle.
