TESA TESE Testicular Sperm Aspiration Extraction

TESA/TESE (Testicular Sperm Aspiration/Extraction)

TESA (Testicular Sperm Aspiration) and TESE (Testicular Sperm Extraction) are advanced sperm retrieval procedures used for men who have little or no sperm present in their ejaculate (azoospermia). These techniques help retrieve sperm directly from the testicles for use in assisted reproductive treatments such as IVF and ICSI.

TESA is a minimally invasive procedure in which a fine needle is used to aspirate sperm directly from the testicular tissue.

TESE involves retrieving a small sample of testicular tissue from which sperm can be extracted in the laboratory. Both procedures are typically performed under local or general anesthesia and usually take 20–30 minutes.

TESA and TESE are commonly recommended for men with obstructive azoospermia, non-obstructive azoospermia, previous vasectomy, or severe male infertility where sperm are not present in the semen sample. The choice between TESA and TESE depends on the underlying cause of infertility and the fertility specialist’s assessment.

Who Needs TESA/TESE?

TESA or TESE may be recommended for men with:

Obstructive azoospermia
Non-obstructive azoospermia
Previous vasectomy
Severe male factor infertility
Absence of sperm in the ejaculate
Failed sperm retrieval through other methods

Benefits of TESA/TESE

Enables sperm retrieval directly from the testicles
Provides sperm for IVF and ICSI treatment
Minimally invasive and relatively quick procedures
Can help men with azoospermia achieve biological parenthood
May allow sperm cryopreservation for future use

What is the difference between TESA and TESE?

TESA involves retrieving sperm using a fine needle inserted into the testicle, while TESE involves removing a small sample of testicular tissue to extract sperm. The most suitable procedure depends on the patient's condition.

Who may benefit from TESA/TESA?

TESA or TESE may be recommended for men with obstructive or non-obstructive azoospermia, severe male infertility, or cases where sperm are not present in the ejaculate.

Is TESA or TESE painful?

Both procedures are usually performed under local or general anesthesia, making them generally comfortable for patients. Mild soreness after the procedure may occur and typically resolves quickly.

What is the success rate of TESA/TESE?

Success rates depend on the underlying cause of azoospermia. Sperm retrieval rates are generally higher in obstructive azoospermia compared to non-obstructive azoospermia. Fertility specialist at Neelkanth IVF can provide a more personalized assessment based on your diagnosis.

Can sperm retrieved through TESA or TESE be used for IVF and ICSI?

Yes. Sperm obtained through TESA or TESE are commonly used in IVF and ICSI treatments and may also be frozen for future fertility treatment cycles.
