Trial TESA (Trial Testicular Sperm Aspiration) is a diagnostic procedure used to determine whether sperm can be retrieved directly from the testicles in men who have very low sperm count or no sperm in the semen, a condition known as azoospermia. In some cases, sperm may not appear in the semen due to blockage or problems with sperm production, and this procedure helps specialists understand whether viable sperm are present inside the testicular tissue.
This procedure plays an important role in planning fertility treatments such as IVF (In Vitro Fertilization) or ICSI (Intracytoplasmic Sperm Injection). By performing a trial TESA before starting treatment, doctors can confirm whether sperm retrieval is possible and decide the most suitable approach for assisted reproduction.
During the procedure, a fine needle is inserted into the testicle under local anesthesia to collect a small sample of testicular tissue. The collected sample is immediately examined in the laboratory by embryologists using specialized microscopes to check for the presence of sperm. The process is generally quick, minimally invasive, and usually takes only a short time to complete.
If sperm are successfully identified in the sample, they may be used in future fertility treatments such as ICSI, where a single sperm is injected directly into the egg to achieve fertilization. In some cases, retrieved sperm may also be frozen and preserved for later use in assisted reproductive procedures.
Trial TESA is commonly recommended for men diagnosed with azoospermia or severe male infertility when sperm cannot be detected in routine semen analysis. It helps fertility specialists better understand the cause of male infertility and allows for more accurate treatment planning.
