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.
TESA or TESE may be recommended for men with:
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.
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.
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.
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.
