DONOSO P., Patricio et al. FECUNDACION ASISTIDA EMPLEANDO ESPERMATOZOIDES FRESCOS Y CRIOPRESERVADOS-DESCONGELADOS OBTENIDOS MEDIANTE BIOPSIA TESTICULAR (TESE). Rev. chil. obstet. ginecol. [online]. 2003, vol.68, n.2, pp.93-96. ISSN 0048-766X.  http://dx.doi.org/10.4067/S0717-75262003000200002.

We performed a retrospective study in obstructive and non-obstructive azoospermic patients in which spermatozooa had been recovered through testicular biopsy (TESE). The main objective was to compare the results of assisted reproductive technique using fresh testicular spermatozoa and frozen-thawed testicular spermatozoa. From a total of 18 cycles in 13 patients, 7 were done with sperm-injected oocyte fallopian transfer (SOFT) and 11 with ICSI and uterine embryo transfer. Fresh spermatozoa were used in 4 patients in the SOFT group and frozen-thawed spermatozoa in 3 patients resulting in 3 and 1 clinical pregnancy respectively. In the ICSI group, 9 cycles used fresh spermatozoa obtaining three prergnancies and two frozen-thawed achieving 1 pregnancy. The fertilization rate was calculed considering only the cycles with uterine embryo transfer resulting in 78% for fresh sperm and 57.14% for frozen-thawed. The pregnancy rate per cycle was 38.46% and 40% for fresh and frozen-thawed sperm respectively. We conclude that the use of frozen thawed testicular sperm for ICSI in azoospermic patients shows comparable results to fresh testicular sperm being an iinvaluable tool for the management of this pathology
