The world's first in vitro fertilization baby was born in 1978 in the United Kingdom. Since then, 8 million babies have been born in the world as a result of IVF and other advanced fertility treatments, according to an international committee.
In vitro fertilization involves taking eggs from a woman and mixing them with spermatozoa. in a petri dish; "in vitro" is Latin for "glbad". Fertilized by this process, the eggs become embryos that can be placed in a woman's uterus, where they can turn into a fetus and possibly a baby.
While IVF births have increased over the last four decades, rates of twins and multiple births have declined, according to the report of the International Committee for the Supervision of Assisted Human Reproduction Technologies, a non-profit organization that disseminates global information. on badisted procreation techniques.
The committee presented its findings Tuesday at the 34th annual meeting of the European Society for Human Reproduction and Embryology. in Barcelona, Spain
Conception by Science
The company was founded in 1985 by Robert Edwards, a Cambridge breeding biologist who helped lead the first in vitro design with gynecologist Dr. Patrick Steptoe. Louise Brown, known at the time as a "test tube baby," 40 years ago at Oldham General Hospital was the first to come from IVF. 19659003] "I do not think my mother, Lesley Brown, could have imagined how big IVF would become and how many babies would be born," said Brown of the 8 million who followed.
More than half a million babies are born each year from IVF and intracytoplasmic sperm injection, over 2 million cycles of treatment
The intracytoplasmic injection of Spermatozoa, whose conception also takes place outside the body, involves the injection of a single sperm. directly into an egg instead of being allowed to naturally fertilize an egg in a petri dish. It was developed in the early 1990s as a treatment for male infertility, although it is now used more generally.
European fertility clinics favor sperm injection compared to traditional IVF of almost two to one, a model that is widespread around the world.
The presentation is based on global data collected from regional registers by the International Monitoring Committee
Assisted Reproductive Technologies
The European Society for Human Reproduction and Embryology also collected registry data national badisted procreation cycles – a unique attempt to achieve conception – carried out in Europe from 1997 to 2015. She found that Spain is leading the continent in badisted procreation, with a record of 119,875 treatment cycles; followed by Russia (110,723 cycles); Germany (96,512); and the former France in the lead (93.918). By comparison, the US Centers for Disease Control and Prevention reported 263,577 total badisted procreation cycles in 463 fertility clinics in a single year (2016), resulting in 76,930 cycles. followed by the European Society for Human Reproduction and Embryology include IVF treatments and intracytoplasmic injection of sperm as well as egg donation, which involves using an egg that does not not been removed from the implanted woman with the resulting embryo. 19659003] In European countries, the pregnancy success rate by embryo transfer is about 36% for IVF and intracytoplasmic sperm injection, according to the report. The rate of single embryo transfers also continues to increase in Europe – from 11% in 1997 to 38% in 2015 – while the multiple birth rate dropped to 14% in 2015, according to the report. .
"The number of [badisted reproductive technology] cycles continues to increase, but use is still heavily influenced by affordable access … which is related to insurance or financing public, "summarizes the report.
generalized freezing and embryo more successful with the introduction of vitrification, a fast freezing technology more effective and safe, according to the report. According to the researchers, Egg donation pregnancy rates are now about 50%.
Although there is an unmet need in Europe, the total number of cycles practiced on the continent is increasing. About 7% per year.
"Good News"
Dr. Gillian Lockwood, Consultant in Reproductive Medicine at IVI Midland, a fertility treatment center in the UK, said the report is a "real good news."
However, Lockwood, who did not participate in the 3 9, study estimates that 8 million is "a fairly conservative estimate."
"We know that there is a huge amount of IVF going on in China and India, which is not necessarily reported or recorded, "she said.
"When I started IVF in 1990, we thought that a 15% pregnancy rate was pretty good." Now, most competent clinics are looking at least 40% for good. patients with prognosis. "In addition, she noted, the multiple pregnancy rate is down and is now at 14%, with a goal of" less than 10%. "
Another point raised by the European Society for Human Reproduction and Embryology There is a huge unmet need for fertility treatments, "she said, noting the report's finding that only a couple Three who tries fertility treatments end up with a baby.The reason for this is "limited cycles" of treatment, Lockwood said.
"After six cycles funded, 70% of couples will have a baby. having invented IVF 40 years ago, has one of the lowest The only woman whose very existence is at the center of any discussion of reproductive technology remains humble and full of hope
Despite the cheering of his birth, "we are just normal people, and I lead a normal life. life, "said Brown of herself and her mother. "There are so many people working in the IVF industry, and they do a fantastic job bringing hope and joy to people and creating families."
