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 کاملUterine Imaging in Infertility and Assisted Reproduction
Uterine pathologies are found to be present in 25% of infertile patients [2] . Structural abnormalities of the uterus, such as leiomyoma, endom etrial polyps, intrauterine adhesions (IUAs), adenomyosis and mullerian anomalies, may affect the reproductive outcome adversely, by interfering with implantation or causing spontaneous abortion. Therefore, exclusion of any uterine pathology becomes an ...

متن کاملRole of Hysteroscopy in Infertility and Assisted Reproduction
The uterus plays a major role in sperm migration, embryo implantation, and fetal development. Congenital uterine anomalies and acquired uterine lesions may affect such uterine functions precluding successful pregnancy. Despite advances in the field of assisted reproductive techniques (ART), only one-third of cycles started end in a pregnancy and one-fourth result in a live birth [1]. Intrauteri...
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 ...
