Testicular Sperm Aspiration (TESA)

TESA stands for Testicular Sperm Aspiration, which is a procedure used to collect sperm directly from the testicles of men who have obstructive or non-obstructive azoospermia, a condition where there is no sperm in the semen. The collected sperm can then be used for in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI).

The TESA procedure involves inserting a fine needle into the testis under local anesthesia, and using a syringe to aspirate small samples of testicular tissue containing sperm. The procedure can be performed as an outpatient procedure and typically takes less than an hour.

TESA can be an effective option for men with azoospermia who have failed to produce sperm with other methods such as testicular biopsy or microdissection testicular sperm extraction (micro-TESE). However, TESA is not always successful in retrieving sperm and may need to be combined with other techniques to increase the chances of success. It is important to discuss the benefits and risks of TESA with Genome consultant to determine if it is the most appropriate treatment option for each individual or couple.
