Cryopreservation of human oocytes and fertilization by two techniques: in-vitro fertilization and intracytoplasmic sperm injection
1 Oct 1995
Abstract excerpt
Human oocyte cryopreservation results in poor survival and subsequent fertilization rates. It has been suggested that freeze-thaw-induced changes in the zona pellucida may impair sperm penetration or attachment. The aim of this study was to compare fertilization and cleavage rates in cryopreserved oocytes inseminated by conventional in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).
