Micro-TESE and OncoTESE
Micro-TESE and Onco-TESE are advanced microsurgical techniques that allow us to retrieve sperm from the testes in azoospermic patients.
What is Micro-TESE?

The Micro-TESE is recommended for people who have abnormal sperm production (non-obstructive azoospermia). There are many causes for this, including previous testicular surgery, previous medical treatment, a genetic problem, or another male factor infertility problem.
The probability of finding sperm with this technique is approximately 50% in most cases. Many studies have shown that Micro-TESE produces the highest sperm retrieval rate and causes the least amount of damage to the testicles compared to other techniques.
What is Onco-TESE?
In the group of patients with severe impairment of the seminogram, the options are reduced to the extraction of testicular sperm, using a microscopic technique, at the time of surgery to remove the testicle with tumor. This technique known as Onco-microTESE is an intervention in which once the testicle with tumor has been removed, the search for sperm is carried out with a magnifying microscope and with the help of an embryologist in the operating room. It is an effective technique for azoospermia and severe oligozoospermia. The success rates depend on the age of the patient and the percentage of tumor occupation in the affected testicle. Overall it has a 50% success rate.
