The primary goal is sperm retrieval. Clinical outcome of fresh testicular spermatozoa of unexpected sperm retrieval failure on the day of egg retrieval are not common but occur more often in patients with severe oligospermia or Non-Obstructive Azoospermia (NOA). Egg freezing is a common strategy after failed sperm collection ovarian stimulation is performed simultaneously. However, the use of vitrification in oocytes is like these cases of male infertility are still not clear. Objective: To investigate the oocyte outcomes arising after sperm failure Recall from patients with severe or Non-Obstructive Oligospermia (NOA) Oocyte retrieval day. Methods: A retrospective group study setting Society for Art Irifiv Scientific Research Group and January 2021- Patients for 203 couples with NOA (n=200) or severe oligospermia (n=3), testicular spermatozoa (n=67 cycles) or frozen sperm (n=209 cycles) were injected into fresh or frozen-thawed oocytes via 276 Intracytoplasmic Sperm Injection (ICSI) cycles. Main Outcome Measures: Clinical pregnancy and live-birth rates (LBRs). Results: In the 67 cycles involving the use of fresh testicular spermatozoa, no significant differences were observed between fresh and warmed oocytes with respect to the fertilization rates.
