:- Techniques :-
PESA- Percutaneous Epididymal Sperm Aspiration
Sperm are collected from the epididymis, where the sperm are stored usually. A needle is directly inserted into the epididymis and aspirated.
TESE- TEsticular Sperm Extraction
Retrieval of sperm from a biopsy or several biopsies from testicular tissue.
:- Procedure :-
This is a minor operative procedure which is carried out under local anaesthesia. A small tissue is biopsied from the testis. The extracted tissues are teased and examined for the presence of sperm on the same day.Usually the sperm extracted by TESE procedure result in a very low number of sperm. It is sometimes possible to freeze the extracted sperm if the number of sperm retrieved are enough.Those frozen TESE sperm are later thawed at the time of ICSI. But sometimes the sperm quantity might not be sufficient or the quality might not be good enough for freezing, hence fresh TESE procedure on the day of ICSI should be carried out.
