Abstract:
PURPOSE: We determined the usefulness of in vitro germ cell culture in nonobstructive azoospermic patients diagnosed with Sertoli cell only syndrome, no sperm in testicular sperm extraction. MATERIALS AND METHODS: This study included 44 patients (45 testicular tissues) with nonobstructive azoospermia who were diagnosed with Sertoli cell only syndrome and were found to have no sperm in testicular sperm extraction between January 2006 and July 2008. Among the 45 testicular tissues, 22 tissues were processed for culture. In the in vitro cultures, the testicular tissues were dissociated and plated on gelatin-coated dishes. Patients were divided into 2 groups according to culture success: group I, culture positive (+; n=10); and group II, culture negative (-; n=12). RESULTS: The mean patient ages were 31.73 and 31.68 years for groups I and II, respectively. The mean testicular sizes were 10.19 and 10.42 cc, respectively; the semen volumes were 2.86 and 3.04 cc, respectively; and the mean FSH, LH, and testosterone levels were 18.86 mIU/ml, 5.99 mIU/ml, and 4.46 ng/ml vs. 21.02 mIU/ml, 6.29 mIU/ml, and 4.32 ng/ml for groups I and II, respectively, with no significant differences between the groups (p>0.05). The culture rate of nonobstructive azoospermic patients diagnosed with Sertoli cell only syndrome was 45.5% (10/22). Round spermatid injection was done in 2 patients with consent of the patients, but implantation failed. Among the 45 tissues, germ cells were found in 8 tissues after pathologic reexamination. CONCLUSIONS: The in vitro culture of germ cells would be useful in the advanced treatment of nonobstructive azoospermic patients.
