TESA: testicular sperm aspiration explained
What testicular sperm aspiration involves, the circumstances in which it may be offered, and how retrieved sperm are used with ICSI.
One of several surgical sperm retrieval techniques.
TESA is used in selected circumstances, most often where azoospermia is obstructive. Retrieval does not always succeed, and where the cause is non-obstructive a micro-TESE approach is usually discussed instead.
Key takeaways
- TESA takes a sample directly from the testis using a needle.
- Any sperm found are normally used with ICSI, often after freezing.
- Success depends on the underlying cause and is never guaranteed.
