TESE (testicular sperm extraction)
A surgical sperm retrieval procedure carried out under local anesthesia. During the procedure a sperm sample may be retrieved from the testes using a small needle aspiration without making a skin incision. The retrieved sperm which have been extracted from the testes is injected in each egg using ICSI (Intra cytoplasmic Sperm Injection) technique for fertilizing the eggs.
When there is no sperm was retrieved by MESA technique, the TESE is performed. Sometimes there is no sperm, either due to blockage in the route between sperm production and ejaculation or partial or complete failure in the sperm production, these men with obstructive and non- obstructive azoospermia is suitable for TESE.
