July 25 – World Embryologist Day!
This date was chosen as World Embryologist Day for one simple reason: on this day, July 25, the first child in the world was born, conceived by in vitro fertilization. British woman Louise Brown turns 37 today, she is married and has a son, born without IVF assistance.
Sir Robert Edwards, the embryologist who helped Luisa’s mother get pregnant, won the Nobel Prize in 2010. His colleague and co-author of the method, gynecologist Patrick Steptoe, did not live to see this award. At the moment, about 5.5 million babies have been born thanks to IVF.
How embryology developed
The pioneers of embryology have gone through a lot of setbacks trying to figure out how to fertilize an egg in the laboratory. Decide in what conditions to grow embryos, when to plant them in the uterus. Until now, embryologists are looking for ways to improve in order to achieve the main thing – the birth of a child.
We will voice the main milestones of embryology, behind which is the great work of many scientists around the world:
1968 – a human egg is fertilized for the first time outside a woman’s body. Before that, unsuccessful attempts were made, which for several years, throwing back, created the impression that this was impossible.
1973 – the first woman becomes pregnant after the transfer of an embryo into the uterus. However, it was not possible to bear the child: there was a miscarriage at an early stage.
1978 – Louise Brown is born, the first child conceived by extracorporeal insemination.
1984 – this year the first child was born after embryo cryopreservation. The method allowed embryos to be frozen for long-term storage and thawed so that they remained viable.
1992 – microsurgical technologies come into embryology. For the first time, the ICSI (Intracytoplasmic Sperm Injection) procedure was performed – the introduction of a sperm into an egg. The use of ICSI technology allows achieving fertilization even in the most severe cases of male infertility, when there are very few sperm.
1993 – molecular genetic technologies are applied in embryology. For the first time, preimplantation genetic diagnosis (PGD) was performed. Now it is possible to exclude genetic pathology in the embryo before it is transplanted into the uterus.
2005 – molecular medicine is used for the first time in work with embryos. Being outside the mother’s body for five days is a stressful situation for the embryo. If you do not try to create a comfortable environment for him to the maximum, some disturbances may occur, for example, cellular fragmentation. The Lada clinic has equipment that creates a natural environment for embryos.
