Abstract
PURPOSE Recent studies have shown that improved clinical outcomes can be achieved by transferring blastocysts rather than cleavage-stage embryos. However, blastocyst transfer is not performed in all patients. The aim of this study was to compare clinical outcomes of intracytoplasmic sperm injection (ICSI) cycles using testicular sperm (TE) with those of ICSI cycles using ejaculated sperm (EJ). METHODS ICSI was performed using EJ in 141 cycles and TE in 37 cycles. Embryos were cultured for 5 days. The quality of embryos was assessed on days 3 and 5 before embryo transfer. RESULTS Fertilization rate was 77.3% in the EJ group and 69.6% in the TE group (p < 0.05). The good-quality embryos on day 3 and 5 were not different between the EJ and TE groups. Embryos did not develop to blastocyst stage in 7 cycles of the EJ group (5.0%) and 2 cycles of the TE group (5.4%). There were no significant differences in blastocyst formation and blastocyst quality (46.1% vs. 47.5% and 5.7% vs 5.8%, respectively) on day 5 between both groups. Embryos were transferred in all cycles. Implantation (22.8 vs. 24.7%), clinical pregnancy (44.7 vs. 43.2%), miscarriage (21.7 vs. 33.3%), and delivery (76.5 vs. 66.7%) did not differ between EJ group and TE group. Clinical outcomes of ICSI were not different between the EJ and TE groups. CONCLUSIONS In conclusion, the potential of testicular sperm supporting embryonic development to blastocysts is comparable to that of ejaculated sperm. Therefore, this study suggests that blastocyst transfer can be a very useful assisted reproductive technique in the ICSI cycles that require the use of testicular sperm, and the clinical outcomes of the cycles are comparable to those of ICSI cycles using ejaculated sperm.

Abstract
PURPOSE The purpose of our study was to use time-lapse in order to evaluate the impact of sperm origin (fresh ejaculate or surgically retrieved) on embryo morphokinetic parameters and clinical outcome in intracytoplasmic sperm injection (ICSI) cycles. METHODS This retrospective monocentric study was conducted in 485 unselected couples undergoing 604 ICSI cycles with embryo culture in the Embryoscope®. Among them, 445 couples underwent ICSI cycle with fresh ejaculated sperm and 40 with surgically retrieved sperm (26 with testicular sperm and 14 with epididymal sperm). Embryo morphokinetic parameters and clinical cycle outcome were compared between fresh ejaculated sperm and surgically retrieved sperm. A subgroup analysis was also conducted between testicular and epididymal sperm ICSI cycles. RESULTS Clinical outcome was comparable between groups according to sperm origin. Although most early morphokinetic parameters were comparable between ejaculated and surgical sperm groups, a few parameters were significantly different between both groups, but with a considerable overlap in their distribution. Late cellular events occurred significantly later in the surgical sperm group than in the ejaculated sperm group. CONCLUSIONS Morphokinetic analysis did not allow us to identify clinically relevant differences between fresh ejaculate and surgically retrieved sperm groups. Further studies are needed, especially concerning the relationship between sperm origin and late morphokinetic parameters, such as blastocyst development.
