TESA -Testicular Sperm Aspiration
Targeted sperm retrieval to support fertility treatment when semen samples don’t contain sperm.
Purpose
ESA (Testicular Sperm Aspiration) is performed to retrieve sperm directly from the testicle for men with azoospermia or severe sperm abnormalities, when sperm may not be present in the ejaculate.
Ideal for men with:
Azoospermia (no sperm in ejaculate)- Obstructive azoospermia
- Non-obstructive azoospermia (selected cases)
- Severe sperm abnormalities where ejaculate sperm is not usable
Our Procedure Overview
A minimally invasive sperm retrieval procedure performed under local anesthesia, with sperm used for IVF/ICSI (ICSI).
Why TESA is Done
TESA helps retrieve sperm directly from testicular tissue in men with azoospermia or when sperm is not available in the ejaculate.
The Procedure
A minor procedure performed under local anesthesia to extract sperm from the testicle using a fine needle aspiration technique.
How Sperm is Used
Retrieved sperm can be used for ICSI (Intracytoplasmic Sperm Injection) as part of IVF, supporting fertilization even in severe male-factor cases.
Key Benefit
Provides an option for IVF/ICSI even when no sperm is present in the ejaculate, expanding treatment possibilities for male infertility.
Benefits & Evidence
TESA success depends on the underlying diagnosis (obstructive vs non-obstructive azoospermia) and overall testicular function. Your specialist will guide expectations based on evaluation findings.
Benefits
- Retrieves sperm directly from testicular tissue in men with azoospermia.
- Enables IVF/ICSI even when sperm is not available in semen.
- Minor procedure, typically performed under local anesthesia
Evidence
TESA is widely used for obstructive and selected non-obstructive azoospermia. Professional guidelines (e.g., ASRM) support sperm retrieval procedures as part of assisted reproduction, with outcomes depending on testicular function and underlying diagnosis.
Results vary based on diagnosis (obstructive vs non-obstructive azoospermia) and individual testicular function.
