Inm-8: Assisted Reproductive Technologies and Genetics
Genetic causes have a considerable involvement in infertility. Well-known examples are some chromosomal translocations or sex-chromosomal abnormalities and Y-chromosome deletions. The most common chromosomal aberrations associated especially with severe oligo- and azoospermia are sex chromosome aneuploidies and chromosomal translocations. Consequently, occurrence of aneuploid embryos will lower...
متن کاملAssisted Reproductive Technologies
Assisted reproductive technologies (ART) are a collection of different techniques designed to help those who are infertile achieve a successful pregnancy [4]. The most popular technology currently in use is in vitro [5] fertilization [6] (IVF), but others include gamete intrafallopian transfer (GIFT), zygote intrafallopian transfer [7] (ZIFT), intrauterine insemination (IUI), and intracytoplasm...
متن کاملDoes embryo culture at low oxygen tension improve ART outcomes?
Even with the endogenous defense mechanisms present in oocytes and embryos, disturbances in embryonic culture processes may lead to an increased generation and buildup of reactive oxygen species (ROS) in culture media. This fact may be associated with various degrees of cellular damage (e.g. membrane disturbances, DNA fragmentation, etc.). Consequently, embryonic fragmentation, apoptosis, or ev...

متن کاملMitochondrial transfer: Implications for assisted reproductive technologies
The use of mitochondrial transfer as a clinic procedure is drawing closer to reality. Here we provide a detailed overview of mitochondrial transfer techniques - both established and recent - including pronuclear, spindle, ooplasmic and blastomere transfer. Reasons as to why some techniques are more suitable for the prevention of mitochondrial DNA disease than others, as well as the advantages a...
