To evaluate the efficacy of subzonal insemination (SUZI) as applied to unfertilized oocytes after initial insemination.Unfertilized oocytes at metaphase II obtained after conventional IVF from 14 patients were selected for reinsemination by SUZI. The fertilization rate and pregnancy outcome were assessed.Of the 57 unfertilized oocytes at metaphase II, 10 (17.5%) became fertilized after SUZI. Eight of the 10 (80%) oocytes showed normal fertilization with two pronuclei while the other two (20%) oocytes were polyspermic. Five (35.7%) of the 14 patients had embryo transfer resulting in two (14.3%) pregnancies. One patient had a spontaneous abortion and the other had a live birth at term.Reinsemination of unfertilized oocytes by SUZI could be of value when fertilization fails after initial insemination. |
