Resumen

ZHANG, Zhihong et al. Live birth after transfer of vitrified-warmed embryo derived from vitrified-warmed oocyte and frozen-thawed sperm following failed ICSI: Case report. Rev. méd. Chile [online]. 2017, vol.145, n.3, pp.402-405. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872017000300017.

Since the first successful pregnancy from a frozen human oocyte was reported, remarkable technological progress has been made in the area of cryopreservation of human oocytes. We report a successful delivery of two healthy babies after transfer of vitrified-warmed embryos derived from intracytoplasmic sperm injection (ICSI) with vitrified-warmed oocytes and frozen-thawed sperm. A female patient and her husband with severe oligoasthenspermia are reported. At the day of oocyte collection, very few inactive sperms were found in her husband semen. Multiple site open testicular biopsy was performed on her husband, but no sperm was retrieved. The patient did not become pregnant after transferring two embryos coming from half of oocytes and inactive sperms. The patient got pregnant and delivered two healthy babies after receiving a transfer of vitrified-warmed embryos from vitrified-warmed oocytes and frozen-thawed sperm.

Palabras clave : Embryo Implantation, Delayed; Embryo Transfer; Semen Preservation.
