Pregnancies and deliveries after injection of vitrified-warmed oocytes with cryopreserved testicular sperm.
The purpose of this study is to report successful pregnancies and deliveries from embryos derived from vitrified-warmed oocytes injected with frozen-thawed testicular sperm. After the vitrification-warming procedure, surviving oocytes from 11 patients were microinjected with thawed testicular spermatozoa, and subsequent viable cleaving embryos were transferred, resulting in four clinical pregnancies.
