TESE and TESA procedures are surgical methods recommended for men who do not have viable sperm cells in their semen. The absence of viable sperm in the semen is also called azoospermia.

It is known that conditions such as some genetic disorders, febrile diseases at a young age, hormonal disorders and receiving chemotherapy treatment cause azoospermia.

TESA Method

The absence of sperm in a man's semen can be due to various reasons. Some of these are due to obstruction of the sperm ducts.In such a case, there is no sperm production in the testicles. However, existing sperm cannot be ejected with semen due to obstruction in the channels. In this case, it is said that there is no sperm due to obstruction (obstructive azoospermia). In cases of occlusion-related azoospermia, small pieces are taken by entering the clogged ducts or testicular tissue with a thin syringe.

The rate of finding sperm in these parts is close to 100%. During the TESA procedure, local anesthesia is applied to our patients in order to prevent them from feeling pain.

If it is determined that there is no obstruction as a result of the TESA procedure, there is either no sperm production in the testicles or there is a limited number of them in certain areas. In such cases, TESE, a similar surgical method, is recommended for our patient.

TESE – Micro Tese Method

TESE means obtaining sperm from the testis by biopsy.Micro TESE method, on the other hand, minimizes the damage to the facilities.Sperm finding rate increases many times over the TESE method. Micro-tese surgery can take up to 2 hours as it requires examination of individual channels. General anesthesia is preferred over local anesthesia due to the length of the operation.

Patients diagnosed with azoospermia can only have children by undergoing IVF treatment. Pregnancy rates are quite high in patients who are found to have sperm production as a result of the TESE operation, especially if the partner's age is young and there is no problem.
