Fertilization and embryo development in a mouse ICSI model using human and mouse sperm after immobilization in polyvinylpyrrolidone.
BACKGROUND For human ICSI, sperm are normally immobilized immediately prior to injection. However, there are some situations when only sperm of questionable viability are available. There are few evaluations of fertilization or developmental problems in human or animal models using sperm having known intervals between immobilization and injection. METHODS Immobilized human sperm were maintain...
متن کاملP-23: Effect of Melatonin on In vitro Maturation, Fertilization and Resulted Embryo Development in Mouse
Background: Melatonin has been recognised as effective reactive oxygen species (ROS) scavenger. antioxident melatonin effects has been expressed in management of cancer, alzheimer, diabet diseases. This study designed to determine the effect of melatonin on in vitro oocytes maturation and fertilization and cleavage and blastocyst development rate of mouse. Materials and Methods: Cumulus - oocyt...

Effect of sperm DNA damage and sperm protamine deficiency on fertilization and embryo development post-ICSI.
The aim of this study was to evaluate the effect of sperm DNA damage and protamine deficiency on fertilization and embryo development post-intracytoplasmic sperm injection (ICSI), and also to assess the effect of protamine deficiency on DNA damage. Semen samples were collected from 28 patients participating in the ICSI programme. Following sperm preparation and ICSI, the remaining processed sem...
متن کاملO-15: Reduced Fertilization After ICSI and Abnormal Phospholipase C Zeta Presence in Spermatozoa from the Wobbler Mouse
Background: Failed fertilization after intracytoplasmic sperm injection (ICSI) can be due to a reduced oocyte-activation capacity caused by reduced concentrations and abnormal localization of the oocyte-activation factor phospholipase C (PLC) zeta. Patients with this condition can be helped to conceive by artificial activation of oocytes after ICSI with calcium ionophore (assisted oocyte activa...
