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 ...

I-8: Role of Sperm Transcripts in Oocyte Activation, Fertilization and Development
It is well established that in addition to generating the diploid state in the zygote, the sperm also endows the oocyte with paternal centrioles, proteins and RNAs. Although the exact roles of mRNA introduced into the oocyte by the sperm are not completely understood. However, literature background, suggested that RNAs may have a vital role in embryo cleavage and further development. Therefore,...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
Male accessory sex gland secretions affect oocyte Ca2+ oscillations during in-vitro fertilization in golden hamsters.
To evaluate the effect of male accessory sex gland secretions on Ca2+ oscillations of oocytes, epididymal or ejaculated spermatozoa recovered from uteri were used to inseminate oocytes. Ca2+ oscillations were measured by Fura 2 fluorescence imaging (F340/F380). We showed that although Ca2+ oscillations induced by ejaculated spermatozoa had a pattern similar to those induced by epididymal sperma...
