P-55: Cryopreservation of Rooster Semen Using Hand-Made Cryopreservation Media Supplemented with Different Cryoprotectants
Background Cryopreservation procedure for poultry semen is not reliable due to structural and biochemical damages which can lead to reduction in sperm quality and fertility. Development of cryopreservation medium has crucial effects for successful recovery of sperm after freezing. The objective of this study was assessment of cryopreservation of rooster semen using hand-made cryopreservation me...
متن کاملCryoprotective effect of different glycerol concentrations on domestic cat spermatozoa.
Cryopreservation of spermatozoa is a pivotal tool in assisted reproduction, and studies aiming to establish optimal freezing/thawing protocols are essential to enhance sperm survival. The objectives of the present study were to (1) compare the cryoprotective efficiency of three different glycerol concentrations (3%, 5%, and 7%) on the basis of post-thaw sperm quality and (2) investigate whether...
متن کاملThe effect of extracellular ice and cryoprotective agents on the water permeability parameters of human sperm plasma membrane during freezing.
A firm biophysical basis for the cryopreservation of human spermatozoa is limited by a lack of knowledge regarding the water permeability characteristics during freezing in the presence of extracellular ice and cryoprotective agents (CPA). Cryomicroscopy cannot be used to measure dehydration during freezing in human spermatozoa because of their highly non-spherical shape and their small dimensi...
متن کاملthe effect of oxytetracycline on serum calcium, phosphorus and magnesium in cattle
نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
15 صفحه اولInvestigation of Different Glycerol and Egg Yolk Concentration on Freezing Bakhtiari Ram Semen
Purpose: Glycerol has been the most widely used cryopreservation agent for spermatozoa and a wide range of factors affects its action on sperm viability and fertilizing capacity. Moreover egg yolk is a common constituent of semen diluents, protects the spermatozoa against cold shock and confers protection during freezing and thawing .The aim of this study was to investigate of different glycero...
