Relationship Between Protamine Deficiency and Acrosin Activity With Fertilization Rate Post ICSI
Purpose: The objective of this study was to evaluate the relationship between some events that simultaneously occur during spermiogenesis, related to protamine deficiency,and acrosomal integrity with fertilization rate post ICSI. Materials and Methods: Semen samples from 68 infertile couples undergoing ICSI at Isfahan Fertility and Infertility center were assessed during this study. Semen anal...
متن کاملP-84: Phospholipase C Zeta: As an Index to Assess Fertilization Potential of a Semen Sample
Background: Failed fertilization post ICSI has been mainly attributed to the sperm’s inability to induce oocyte activation. Phospholipase C Zeta (PLCζ) is considered to be a primary factor for the induction of oocyte activation. The aim of this study was to quantitatively assess the expression of PLCζ in globozoospermic or individuals with previous low or failed fertilization in comparison to f...
متن کاملP-124: Association between Fertilization Rate and Externilization of Phosphatidyl Serine
Background: Externalization of PS (EPS) is considered as a sign of early apoptosis. In addition, EPS also occurs during capacitation and the acrosome reaction. During this study we aimed to evaluate the relationship between EPS and fertilization, embryo quality and pregnancy outcomes in couples who were candidates for ICSI. Materials and Methods: Semen samples (n = 43) were collected from infer...
متن کاملO-26: Evaluation of the Relationship betweenFollicular Fluid Anti- Mullerian Hormone Levelsand Fertilization and Embryo Quality inART Cycles
Background: To evaluate whether success of fertilization and embryo quality are more probable when follicular fluid Anti-mullerian hormone levels are higher . Materials and Methods: 62 women who underwent IVF cycle were divided into fertilized oocytes group (n=42) and non- fertilized oocytes group (n=20) . Follicular fluid Anti-mullerian hormone levels were measured in both groups. Results: Ant...
متن کاملP-19: Effect of Three Sperm Preparation Methods on Sperm DNA Integrity and Oocyte Fertilization Rate
Background: Techniques of sperm preparation require centrifugation to separate spermatozoa from the seminal plasma. The centrifugation can induce damage to the spermatozoa and increase reactive oxygen species(ROS) productionspecially in leukospermic speciemens that are associated with impaired function and fertilizing capacity. However in ICSI, fertilization can occure with damage DNA sperm but...
متن کاملSperm quality, egg size, fecundity and their relationships with fertilization rate of grass carp (Ctenopharyngodon idella)
Gametes were collected by abdominal massage from 15 anesthesized male and female grass carp. In collected sperm samples the following mean spermatological properties were determined: sperm volume 15.64 ± 5.39 mL, sperm motility 81.20 ± 7.61%, motility duration 62.06 ± 19.40s, density 17.88±5.48 x109 mL-1, total density 428.90±302.05 x109, and pH 7.25±0.81. Also egg size (mm) and fecundity (egg...
