The scheduled ovarian hyperstimulation method makes it easy to perform ICSI with fresh testicular sperm (ICSI/TESE).
The authors evaluated whether scheduled ovarian stimulation makes it easy to perform ICSI with fresh testicular sperm. Scheduled ovarian hyperstimulation was applied for testicular sperm extraction and ICSI with fresh testicular spermatozoa. Fifteen cycles in 10 couples were included in the present study; all couples were azoospermic, 5 were obstructive, and the remaining 5 were nonobstructive. No cycles were canceled, and all oocyte retrievals were performed on the scheduled day. Testicular sperm were obtained in 14 treatment cycles (93%). The mean numbers of retrieved and injected oocytes were 9.4 and 6.4, respectively. The fertilization and cleavage rates were 47 and 91%, respectively. Embryo transfers were performed in 12 cycles except 2 cycles that had no embryos. The number of transferred embryos was 2.3. Two clinical pregnancies were obtained. This scheduled ovarian hyperstimulation was applicable for ICSI with fresh testicular sperm.
