This article is from Journal of Reproduction & Infertility, volume 14.AbstractBackground: We performed this study to evaluate use of fresh and frozen sperm samples in non-obstructive azoospermia microdissection testicular sperm extraction micro-TESE-ICSI treatment. Methods: We performed a total of 82 consecutive in vitro fertilization IVF cycles at Fertijin IVF Center in Istanbul, Turkey from January 2010 to March 2012. In 43 participants we used fresh sperm and frozen sperm in the remaining 39 cases. We used fresh and frozen thawed micro surgical testicular sperm extraction micro TESE sperm for ICSI with metaphase II MII oocytes. Results: Frozen microTESE sperm was used in 39 cycles, while 43 ICSI cycles were performed using fresh microTESE. Neither the age of male partners 38.33±5.93 and 38.13±8.28 nor that of the female participants 33.16±6.38 and 33.33±6.97 showed significant difference between fresh versus the microTESE and frozen treatment groups, respectively. FSH concentrations were 14.66±13.93 mIU-ml in fresh TESE group and 17.91±16.29 mIU-ml in frozen group with no correlations or differences between the two groups. The average number of mature oocytes injected with sperm was 9.23±3.77, versus 9.26±5.26 in cycles using fresh and frozen microTESE sperm, respectively. Fertilization rate was not significantly different in the fresh microTESE 44.79% than frozen TESE sperm group 46.76%. The average number of transferred embryos was 1.60±0.49 in fresh sperm group and 1.59±0.50 in frozen sperm group. All embryo transfers were performed on day 3. Conclusion: Cryopreservation of testicular sperm tissues is more suitable and of great benefite if carried out before ovulation induction and not after, especially in cases with non-obstructive azoospermia.
