Methods of Assessment of Cryopreserved Semen
Despite the significant progress, the post-thaw viability and fertility of the cryopreserved sperm are still reduced, as a consequence of accumulated cellular injuries that arise throughout the cryopreservation process. Many laboratory tests have already been carried out to verify these detrimental effects and their origin. Their is needed to well understand the whole process of cryopreservatio...
متن کاملon the comparison of keyword and semantic-context methods of learning new vocabulary meaning
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
15 صفحه اولThe Effects of EGTA on the Quality of Fresh and Cryopreserved-Thawed Human Spermatozoa
Background: Sperm cryopreservation-thawing process has damaging effects on the structure and function of sperm, namely cryoinjury. Calcium overload has been reported as a postulated mechanism for sperm damage during the first steps after thawing. This study was designed to assess the intracellular calcium (Ca2+i) after cryopreservation and to clarify the role of a calcium chelator ethylene glyc...
متن کاملRisk of cytomegalovirus transmission by cryopreserved semen: a study of 635 semen samples from 231 donors.
BACKGROUND The hypothetical responsibility of sperm donation in cytomegalovirus (CMV) transmission to recipients and precautions to prevent this transmission are widely discussed. The aim of this French CECOS Federation study was to evaluate both the reality and the importance of the CMV risk due to donor sperm and the relevance of measures used to screen it. METHODS We conducted a prospectiv...
متن کاملEffect of Semen Plasma and Blood Serum for Motility % and Capacitation Status of Cryopreserved and Thawed Ram Semen
The quality control involved utilising various methods of frozenram semen and optimising the cryopreservation technology, which are both very important tasks. The experiments were carried out using light microscopy and CTC fluorescent staining on the various stages of ram semen samples preparing for cryopreservation procedure, thawing and incubating (at 39 oC, 2 hours) in the various compositio...
