Differentiation Between the Effect of Protamine Deficiency and Failed Oocyte Activation on Fertilization Post ICSI
Sperm premature chromosomal condensaion (PCC) and failed oocyte activation are considered to result in failed fertilization post intracytoplasmic sperm injection (ICSI). Recent studies also suggested that sperm protamine deficiency may induce PCC. The ain of this study was to assess the effect of failed oocyte activation and protamine deficiency on failed ferilization post ICSI and to indicate ...
متن کاملEffect of Protamine Deficiency on Fertilization Outcome and Incidence of Sperm Premature Chromosomal Condensation Post ICSI
Purpose: After aneuploidy,sperm premature chromatin condensation (PCC) is the next most important cause of fertilization failure. Therefore the aim of this study is to evaluate the effect of sperm protamine deficiency on sperm PCC formation post ICSI. Materials and Methods: Cytogenetic analysis was carried out on unfertilized oocytes post ICSI and incidence of sperm PCC was evaluated. The resu...
متن کاملEffect 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...
