Evaluation the Efficacy of HBA Sperm- Hyaluronan Binding Assay Method in Infertility Centers
Introduction: The novel development of the (HBA) sperm- hyaluronan binding assay has now been routinely used in some laboratories worldwide to predict sperm maturity and functionality. The purpose of this study was to evaluate the correlation between HBA score and histone deficiency, protamine content and DNA fragmentation. Methods: During April- March 2012 patients who were enrolled at ...

متن کاملP-137: Improvement in Post-Thawed Ram Sperm Quality by Adding Cysteine in Soybean Lecithin Based Extender
Background: Ram sperm have a higher polyunsaturated fatty acids and a lower cholesterol/phospholipid ratio than other species which renders the sperm much more vulnerable to oxidative damage caused by reactive oxygen species (ROS). Oxidative stress can affects the integrity of cells at both the structural and sub structural levels. Therefore, a suitable antioxidant may prevent cryo-injuries and...
متن کاملEffects of Centrifugation and Different Levels of Soybean Lecithin-Based Extender on Post-Thaw Sperm Quality of Ghezel Ram Semen
The objective of this study was to specify the effects of centrifugation and different surface of soybean lecithin-based extender on post-thaw Sperm quality of Ghezel ram semen. Semen samples were gathered from 5 mature Ghezel ram two/week for 3 weeks. After initial evaluation, the approved semen samples were pooled together and split into equal parts in Falcon tubes. Three samples were combine...
متن کاملP-127: In Vitro Assessment of Trehalose for Cryopreservation of Ram Sperm in Extender Containing Soybean Lecithin
Background: Trehalose, a non-permeable disaccharide, has a protective role related both to osmotic effect and specific interactions with membrane phospholipids, rendering hypertonic media, causing cellular osmotic dehydration before freezing, and then decreasing the amount of cell injury by ice crystallization. Within this study, an attempt was made to evaluation of two levels of 50 and 100 mM ...
