TESE is used in patients who have no sperm cells in their ejaculate (azoospermia).
It is a minimal operation to obtain sperm from the testicles where sperm is produced.

is a candidate. Patients undergo genetic examination before the operation. Sex determinant in men
Y chromosomes are examined. On the Y chromosome is the chromosome responsible for sperm production.

will not be seen. However, unless there is a major problem in the AZF area, azoospermic
TESE can be easily applied to patients.

The sperm taken from the operation site can be frozen and used again when necessary.
However, when the frozen tissue is thawed, good quality sperm may not always be obtained. This
in which case a second TESE operation may be necessary. Likewise, with the first TESE operation
If the number and quality of the sperm collected is found to be insufficient, a second TESE operation may be performed.
In summary, this operation can be repeated until a high quality and sufficient number of sperm is obtained. TESE
If the operation is to be repeated, it would be correct to have 6 months between the two procedures.
WHAT IS THE SUCCESS RATE OF TESE OPERATION?
Although the success rate of the TESE procedure varies from person to person, it is estimated that 40 percent of patients with azoospermia
In 60% of cases, good quality and sufficient number of sperm can be obtained.
