What is TESA?
TESA (Testicular Sperm Aspiration) is a minor surgical procedure used to collect sperm directly from the testicular tissue. It is typically recommended for men with no sperm in their semen (azoospermia).
Who Can Benefit from TESA?
- Men with obstructive azoospermia (blocked sperm ducts)
- Non-obstructive azoospermia where testicular sperm production is low
- Men who previously had vasectomy and now want biological children
- Couples considering IVF/ICSI using surgically retrieved sperm
The TESA Procedure
- Preparation: Local anesthesia is given to numb the testicular area.
- Aspiration: A fine needle is inserted into the testis to aspirate tissue containing sperm.
- Processing: The retrieved tissue is processed in the lab to extract live sperm.
- Usage: Extracted sperm are used for ICSI (Intracytoplasmic Sperm Injection).
Success Rates
TESA combined with ICSI has helped many couples with male factor infertility achieve pregnancy. Success depends on testicular sperm availability, egg quality, and female partner’s age.
Risks & Considerations
- Mild pain or swelling at the aspiration site
- Bruising or temporary discomfort
- Rare risk of infection
- Requires IVF/ICSI for fertilization
