Epigenetic Alterations in Density Selected Human Spermatozoa for Assisted Reproduction.
Epidemiological evidence indicates that assisted reproductive technologies (ART) may be associated with several epigenetic diseases such as Beckwith-Wiedemann syndrome (BWS) or Silver-Russell syndrome (SRS). Selection of sperm by density-gradients in ART has improved DNA integrity and sperm quality; however, epigenetic alterations associated with this approach are largely unknown. In the presen...
متن کاملEvaluation of nuclear DNA damage in human spermatozoa in men opting for assisted reproduction.
Diagnosis of sperm DNA integrity of semen sample is important for consistently high reproductive efficiency. The conventional parameters of semen analysis take into account morphology, motility, and concentration of spermatozoa in the sample, which are insufficient for evaluation of reproductive potential. Current studies have implicated abnormal organization of genomic material in sperms as a ...
متن کاملNew Methods for Selecting Stallion Spermatozoa for Assisted Reproduction
Improved sperm selection techniques are needed to increase the efficiency of equineassisted reproduction. Single layer centrifugation (SLC) of spermatozoa has been shown to improve the quality of stallion sperm samples. In this study, the functionality of selected stallion spermatozoa was tested by intracytoplasmic sperm injection of equine oocytes after selection by SLC through Androcoll-E or ...
متن کاملAssisted Human Reproduction Canada (AHRC)
Established under the Assisted Human Reproduction (AHR) Act of 2004, Assisted Human Reproduction Canada [5] (AHRC), also known as the Assisted Human Reproduction Agency of Canada, was created in 2006 to oversee research related to reproductive technologies and to protect the reproductive rights [6] and interests of Canadian citizens. AHRC serves as a regulatory body for the development and use ...
متن کاملParthenogenesis and Human Assisted Reproduction
Parthenogenetic activation of human oocytes obtained from infertility treatments has gained new interest in recent years as an alternative approach to create embryos with no reproductive purpose for research in areas such as assisted reproduction technologies itself, somatic cell, and nuclear transfer experiments and for derivation of clinical grade pluripotent embryonic stem cells for regenera...
