Embryo transfer

oocytes that will turn into an embryo. When the donor is being flushed during a conventional flush she is…

Dreisch was the the first scientist that demonstrated artificial “ embryo twinning”. Dreisch realized if he shook a embryo of a sea urchin he could separate them and make two sea urchins. In this experiment he showed that each cell in its early stage in the embryo has its own complete set of genetic instructions that can grow into a full organism. The sea urchins both grew and lived. Scientist soon became fully aware of the whole “embryo twinning” and started doing their own evaluations on the…

History of IVF The history of IVF dates way back to the 1890s where professor Walter Heape reported the first ever embryo translation at the university of Cambridge, London. This was long before anyone thought of applying this to humans. In 1932, Aldous Huxley publishes a book called ‘brave new world’ this is a science fiction novel but Aldous describes IVF very realistically. In the year 1934, two representatives from the laboratory of general physiology, Harvard university, Pincus and EnzMann…

growing a cloned embryo inside of a surrogate animal. The third type of cloning is Therapeutic cloning in which one of the goals is to produce stem cells that can be used for replacing diseased tissue and other medical benefits. The process of cloning is also very important. There are a couple of ways that scientists can create a clone, one of which is artificial embryo twinning and the other is somatic cell nuclear transfer. The first process to be discovered was artificial embryo twinning;…

reproductive technology (ART)? Assisted reproductive technology (ART) is a method in which a woman's eggs are removed, mixed with sperm to make embryos, and the embryos are placed back in the woman's body. Depending upon a woman’s age, ART has a success rate of about 11% to 39%. Four types of ART are in vitro fertilization, zygote transfer, gamete transfer, and intracytoplasmic sperm injection. • In vitro fertilization (IVF) means that fertilization takes place outside of the body. IVF is the…

itself, has many advantages and disadvantages, especially when implanting more than one embryo at a time. IVF is a very expensive procedure and since more than 80% of the embryos transfer fail to implant; doctors sometimes rather transfer multiple embryos at a time in order to increase the likelihood of pregnancy. However, this can definitely cause some ethical implications. The process of transferring multiple embryos at a time may be a plus financially but it can cause multiple gestation,…

birth or, specifically, the mitochondrial transfer technique is a procedure that allows to replace a small amount of defective DNA in mother’s egg with a normal DNA from a second woman, therefore babies inherit genes from two mothers and one father. Consequently, the resulting baby has 20,000 genes on 23 pairs of chromosomes from its mother and father. The donor donates only DNA that is in mitochondria (less than 0.2% of total DNA). Two mitochondrial transfer techniques exist, both use in vitro…

nuclear transfer. ‘Somatic cell nuclear transfer’ refers to the process in which the nucleus of a somatic cell of an existing (or previously existing) organism is transferred into an oocyte from which the nucleus has been removed.” (Pros and Cons of Human Cloning, 2017). There are three different types of cloning: gene, reproductive and therapeutic. Of the three types the ones that are under much debate is reproductive and therapeutic cloning. Reproductive cloning is producing an embryo that is…

You may have known someone who has gone through IVF and have heard about the infamous shots and other aspects of the treatment. Chances are that unless you have gone through infertility, you haven’t been exposed to the depth of what this process really entails. Join me as I take you on a tour of what it is like to struggle with infertility and undergo the oppressing, all consuming IVF process. The IVF process, from start to finish Tour stop #1: You enter an office filled with pleasant, smiling…

that most interests me at this year’s Nobel Conference is mitochondrial DNA transfer. This is a controversial treatment in which a mother’s mitochondrial DNA is swapped for a donor’s mitochondrial DNA. Along with using the resources found on the Nobel Conference webpage, I watched a SciShow video, “Babies with Three Parents,” on YouTube and also read a Nature article, “US Panel Greenlights Creation of Male ‘Three-Person’ Embryos,” written by Sara Reardon, in order to learn more about this new…
