OBJECTIVE: To compare the outcomes of first-attempt IVF-intracytoplasmic sperm injection (ICSI) cycles when using fresh testicular biopsy samples vs. frozen biopsy samples. DESIGN: Retrospective chart review of 92 consecutive first-attempt IVF-ICSI cycles. SETTING: Two IVF programs. PATIENT(S): Forty consecutive first-attempt IVF-ICSI patients using sperm from fresh testicular biopsy samples and 52 consecutive first-attempt IVF-ICSI cycles using frozen testicular biopsy samples. INTERVENTION(S): Testicular biopsy, IVF-ICSI with fresh and frozen-thawed spermatozoa. MAIN OUTCOME MEASURE(S): Fertilization rates, embryo quality, pregnancy, delivery, and spontaneous abortion rates. RESULT(S): A significantly increased ICSI fertilization percentage was obtained with frozen testicular biopsy samples (76.5% +/- 3.1%) vs. fresh biopsy samples (68.3% +/- 2.6%). However, embryo quality, pregnancy, and delivery rates were higher in the fresh biopsy group. Mean embryo score was 4.54 +/- 0.31 and 3.62 +/- 0.2 in the fresh vs. frozen group, respectively. Chemical pregnancy rates (60% vs. 49.1%), clinical pregnancy rates (56.4% vs. 41.2%), and delivery rates (48.7% vs. 31.2%) were each higher in the fresh group vs. frozen group. Accordingly, the spontaneous abortion rate was lower in the fresh group (21.7%) vs. the frozen group (33.3%). CONCLUSION(S): Although the use of frozen biopsy samples has logistical advantages, we conclude it may be advantageous to use fresh testicular biopsy samples in IVF-ICSI cases whenever possible, as fresh specimens yielded significantly improved embryo quality, generally higher pregnancy rates, and lower spontaneous abortion rates.
