ABSTRACT
OBJECTIVE:
To evaluate diagnostic procedures and surgical sperm retrieval in men with suspected obstructive azoospermia who wish to father children.DESIGN:
Descriptive, retrospective.METHOD:
During the period 1 April 1999-31 December 2001 93 men suspected of having obstructive azoospermia underwent surgical sperm retrieval by means of percutaneous epididymal sperm aspiration (PESA). In each patient a testicular biopsy was performed to determine the Johnsen score (a score > or = 8 is equivalent to a normal spermatogenesis). Cryopreservation was performed whenever possible. The findings in both percutaneous and surgical sperm retrieval were compared.RESULTS:
In 76 patients (82%) epididymal motile sperm were obtained using PESA. Their Johnsen score on the testis biopsy was 9.1 (range 7.4-10). In 73 of the patients the Johnsen score was > or = 8. In the 17 patients (18%) in whom no sperm were found with PESA, the median Johnsen score was 5.8 (range 2-9.8). Epididymal sperm were not found in patients with a testicular volume < 15 ml. In all 28 patients who had undergone a vasectomy in the past, motile sperm were found along with a Johnsen score > or = 8. In 23 of the 24 patients with congenital bilateral absence of the vas deferens (CABVD) the Johnsen score was > or = 8. Cryopreservation was possible in 45 (59%) of all patients and in 5 (35%) of the 13 patients with an unknown cause for the obstructive azoospermia.CONCLUSION:
In men with suspected obstructive azoospermia in whom sperm were found using PESA, a diagnostic testis biopsy provided no additional relevant information about the spermatogenesis. There was always a good spermatogenesis after vasectomy. CBAVD patients probably had at least some focal areas in the testes with normal spermatogenesis. Sperm retrieval and cryopreservation could be carried out less frequently in the case of obstructions with an unknown cause.
