The primary goal is sperm retrieval. Indications 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. Egg freezing is a common strategy after failed sperm collection Ovarian stimulation is performed simultaneously. However, the use of vitrification in oocytes is like this 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 Oocyte retrieval day.

Methods: A retrospective group study Setting association for scientific research of the IRIFIV-AISRG group and January 2021- Patients: For 203 couples with non-obstructive azoospermia (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 cycles.

Main Outcome Measures: Clinical pregnancy and live-birth rates.

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.

Conclusions: Emerging oocyte freezing is a feasible strategy for unexpected sperm management Retrieval failure of oligospermia or Non-Obstructive Azoospermia patients on the day of oocyte retrieval. over there It has no adverse effect on the live birth rate of frozen testicular or Sperm is injected into the thawed eggs compared to fresh eggs.
