Sperm progressive motility has been reported to be one of the key factors influencing in vitro fertilization rates. However, recent studies have shown that sperm DNA fragmentation is a more robust predictor of assisted reproductive outcomes including reduced fertilization rates, embryo quality, and pregnancy rates. This study aimed to compare the usefulness of sperm progressive motility and DNA...

Background: Application of follicular fluid (FF) and platelet-activating factor (PAF) in artificial insemination improves sperm motility. Lactate dehydrogenase C (LDH-C) is a key enzyme for sperm motility. In this study, the effects of FF and PAF on the sperm motility index and LDH-C expression were investigated. Moreover, LDH-C expression was compared between asthenozoospermic and normozoosper...

background: evaluating the significance and the effects of plant-derived drugs on laboratory animal’s fertility was recognized. there was antioxidant activity reported from heracleum persicum (golpar).objective: current study aims to study the antioxidant effect of golpar extracts on sperm parameters and chromatin quality in mice.materials and methods: eighteen adult male mice were divided to 3...

Canine seminal plasma contains antioxidant enzymes to protect sperm against internally generated ROS. These enzymes are removed from seminal plasma during the process of cryopreservation. The freezing/thawing process can cause some morphological and functional changes via ice crystallization and osmolality imbalance. The present study was conducted to evaluate the effects of curcumin supplement...

Background: This study investigated the probable effects of daily administration of methamphetamine (MA) on sperm motility, acrosome reaction (AR), acridine orange (AO), sperm chromatin dispersion (SCD) test and chromomycin A3 (CMA3) in mice. Materials and Methods: Twenty four NMRI male mice were administrated three different doses of MA intraperitoneally (n=6 in each group). Different doses of...

Background: Exposure of sperm membranes to Reactive Oxygen Species induces lipid peroxidation causing membrane breakdown and loss of function. A rosemary extract as dietary additive was assayed for antioxidant effectiveness to improve the quality of rooster semen. Although rosemary extract has been evaluated for in vitro study of semen preservation, up to date no study has been conducted to exa...

Introduction & Objective: The aim of this study was to investigate the effect of electromagnetic field on the count and motility of adult rat's sperms and the protective effect of different dosages of zinc sulfate on it. Materials & Methods: Thirty two adult male rats were subdivided randomly into 4 groups: group1:serve as untreated controls,group2:was exposed to an electromagnetic field bu...

Abdy K, Arshady N Dolat Panah M Rezaei Topraggaleh T,

Background: In mammalian spermatozoa, motility is one of the most important parameters for evaluating the quality of the semen. From a functional point of view, motility is strongly related to the spermatozoa’s ability to manage its energy status, Thus, modulation of energy status could be translated into significant changes in motility patterns. The aim of the present study was to evaluate xyl...
