چکیده
In its simplest term, IVF is simply the uniting of egg and sperm in vitro (in the lab). Subsequently the embryos are transferred into the uterus through the cervix and pregnancy is allowed to begin. IVF was the first of the ART techniques to be developed. The first birth was in 1978 in England. The procedure was pioneered by a Gynecologist and a Ph.D. (Drs. Steptoe and Edwards). Next came GIFT, which stands for gamete (egg and sperm) intrafallopian transfer. This procedure requires laparoscopy, which is a small incision surgery and requires a general anesthetic. With existing technology, pregnancy rates are similar with IVF and GIFT. Since IVF does not require surgery, it has supplanted GIFT.

متن کاملP-67: Quantitative Expression of Pluripotency Specific-Genes in Mouse Blastocysts Produced by In Vitro Fertilization
Background: The efficiency of in vitro fertilization (IVF) is still low to be developed to blastocyst stage probably because of environmental conditions. It is likely that in vitro environment can not exactly mimic in vivo environment due to differences in media, metabolic content, atmospheric composition, temperature and pH. Therefore it may affect embryo quality by changing in embryo gene exp...
