Abstract
The objective of this study was to compare optical loupe with surgical
microscope as regard to sperm retrieval rate (SRR) in microsurgical
TESE in cases with NOA. Eighty four patients with non-obstructive
azoospermia were subjected to microsurgical testicular sperm extraction
(TESE) using optical loupe (8x) for one side. If the initial search at the
operation theater was negative for sperm, the other testis was opened
using surgical microscope (20 – 32x). In 31 patients, the initial search
proved to be positive for sperm and there was no need to open the contralateral
testis. In the other 53 patients, TESE using surgical microscope
were performed. After prolonged search in the embryology laboratory
sperm were found in 10 patients. Three patients were positive for sperm
in the loupe side only, two patients were positive in the microscope side
only. In the remaining five patients sperm were retrieved from both sides.
The overall SRR was 48.8%. In conclusion, the use of optical loupe with
magnification 8x can achieve SRR comparable to the surgical microscope
during microsurgical TESE in cases of non obstructive azoospermia.
