Purpose : Because testicular biopsy traditionally has been performed as a separate
operation, there are some needs for immediate interpretation of the testicular biopsy
specimen in obstructive azoospermia patients. The realization that a proportion of
patients with nonobstructive azoospermia harbor spermatozoa in their testicular
parenchyma, combined with the ability of intracytoplasmic sperm injection(ICSI) to effect
pregnancy with single sperm, has prompted clinicians to explore testicular sperm
extraction(TESE) in these patients. We performed this study to investigate the meaning
of touch imprint and TESE.
Materials and Methods : Fifty-two patients with azoospermia underwent touch imprint,
TESE and simultaneous formal testicular biopsy. Testicular biopsy tissue was touched
on a slide and stained using a Diff-Quik method. Tissue obtained from TESE was
analyzed by intensive searching to find spermatozoa.
Results : Twenty-nine patients were determined as obstructive azoospermia including
two cases of hypospermatogenesis, all patients had sperm seen on touch imprint and
TESE. The other patients were diagnosed as nonobstructive azoospermia, testicular
histology was divided into two main patterns: Sertoli cell only syndrome, spermatocytic
arrest. Touch imprint failed to show sperm, but three of twenty patients(15%) with
Sertoli cell only syndrome had sperm present during TESE.
Conclusions : Touch imprint provides high quality cellular detail for immediate review,
which can minimize the intraoperative time required to decide upon the appropriateness
of correcting the ductal obstruction in obstructive azoospermia patients. Men with
nonobstructive azoospermia may have mature spermatozoa present within their testicular
parenchyma. Therefore intensive searching for presence of spermatozoa should be
performed in tissue obtained from TESE by trained specialist.
