Effect of chromatin condensation on frozen-thawed sperm DNA integrity in normozoospermic men
Background and Aim: Sperm cryopreservation is a common technique used for management of male infertility. But this method has detrimental effects on sperm DNA and chromatin quality. Evaluation of different markers associated with the health of genetic material of sperm is beneficial for determination of the fertility of sperm. The aim of this study was to assess the effect of sperm chromatin co...
متن کاملP-1: Morphine Has Detrimental Effects on Sperm Parameters, Chromatin Quality and DNA Integrity in Mice
Background Morphine as a natural alkaloid (opiate) is considered as one of the problems associated with poor semen production and sperm quality. For the first time, this experimental study was carried out to evaluate the impact of intra-peritoneal injection of morphine on sperm parameters, chromatin quality and DNA integrity of spermatozoa aspirated from cauda epididymis of mice. MaterialsAndMe...
متن کاملP-72: Effect of Subinguinal Varicocelectomy on Human Sperm DNA Integrity and Semen Parameters
Background: Varicocele occurs in approximately 15% to 20% of the male population and it is the most common cause of poor semen parameters. It has been demonstrated that patients with varicocele have poor chromatin packing, DNA damage and nuclear anomalies than the healthy men. Therefore, the aim of this study was to evaluate sperm chromatin integrity and semen parameters in these patients after...
متن کاملEffect of PolyVinyl Pyrrolidone on Sperm Membrane Integrity and Chromatin Status
Background The aim of present study is to evaluate the effect of PolyVinyl Pyrrolidone (PVP) routinly used during ICSI procedure on sperm membrane integrity, and sperm chromatin status. MaterialsAndMethods This study was carried out on 21 semen samples from the infertile men referring to Isfahan Fertility and Infertility Center. The processed semen samples were divided into two portions. One po...
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...
