The TESE method (Testicular Sperm Extraction) is a procedure used for patients whose sperm cannot be retrieved. During the TESE operation, small pieces are taken from the regions where the sperm recovery rate is highest and sperm retrieval is carried out in the laboratory. The painless procedure is performed under general anaesthesia.
What is Micro TESE?
Micro Tese is the search for sperm in tissue taken by microscopic surgery from patients who have no sperm in their semen. Compared to the classic Tese method, fewer samples are taken, reducing the possibility of damage to the testicular tissue.
How is the micro-TESE surgery applied?
The micro-TESE procedure, which is performed under anaesthesia, is painless. Tissue samples are taken from at least 4 different points in two testicles under the microscope and some procedures are performed. After the live sperm cells are separated, these preserved sperm cells are frozen and stored. Then the sperm cells are used in the microinjection procedure. It has the advantage that the sperm cells obtained during the micro-TESE operation are frozen. Thus, if desired, sperm can be used for IVF treatment by thawing. Since the quality of the frozen sperm cells does not deteriorate, they can be used in the second or even third in vitro fertilisation procedure if many sperm cells have been obtained.
Can the Micro-TESE procedure be used again?
If no sperm could be collected during the first Micro-TESE procedure or only a few sperm were collected, it can be used again at the patient's request. In addition, when thawing the previously frozen sperm, there may be a loss of 30-40% of the sperm. In this case, the Micro-TESE procedure can be used for the second time. Only for the second operations, at least 6 months must have passed. The micro-TESE operation can be performed until sperm are retrieved. However, it should be remembered that it is a surgical procedure and affects the testis every time.
Are there any risks of the Micro-TESE surgery?
There are some risks after the procedure such as infections, bleeding, pain. To prevent these situations;
Ice is applied to the treated area for 24 hours.
It can be ensured that the testicles are higher.

For patients without sperm ducts.
For patients with obstruction in the sperm ducts.In patients with hormonal problems.
In patients with an infection.
Patients who are receiving cancer treatment, taking medication, receiving chemotherapy or radiation.
The genes that make sperm production possible are on the Y chromosome, and problems in these genes cause problems with sperm production. It is used in patients with genetic problems.
What should be done before the Micro-TESE operation?
If blood thinners are used, they should be discontinued beforehand.
You should not eat or drink anything for at least 6 hours before the procedure.
The area to be treated should be cleaned with a razor blade.
After the micro-TESE you may experience pressure and pain in the testicles, so you should wear comfortable clothing.

You can take a bath 5 days after the procedure.
You can use painkillers if you have pain.
