Even though the first IVF procedure on animals was performed in , it would take a while before IVF was viable for humans. Some failed attempts at IVF on people occurred in the early s. In , The Lancet reported about an Australian research team at Monash University able to achieve the first human IVF pregnancy, but the pregnancy ended after a few days.
In , some reports noted an ectopic pregnancy through IVF that was non-viable given the circumstances. In addition to these unsuccessful attempts at IVF, we should also mention a controversial attempt to perform IVF in Patrick Steptoe and Dr. Robert Edwards performed the procedure in England, resulting in the birth of Louise Brown on July 25, Louise is still alive and well today, and living proof of the innovations made over a few decades.
With the first live birth of a baby conceived through IVF, building families became more accessible and common for others around the world. Even though doctors proved that IVF could be done safely and successfully, it would take a little time before IVF became widely accessible. That is what happened during the s, as more and more people started turning to IVF and other procedures to get pregnant and start families.
Improvements in medical equipment and refinements in IVF techniques would occur continually throughout the decade. By , over 1, children were born via IVF. Since that time more than 4 million children have been born from IVF and it is used in about 3 percent of all live births in developed countries. IVF is also frequently used as a method for fertility preservation for cancer patients. In such cases, women who can, delay cancer treatment to mature multiple eggs and then have them removed and fertilized.
In contrast to Lesley Brown, fertility preservation patients can now cryopreserve, or freeze, their embryos for transfer after cancer remission.
As many cancer patients cannot delay treatment, the Oncofertility Consortium developed ovarian tissue cryopreservation OTC to help women preserve their fertility without a delay in chemotherapy or radiation. We continue to develop additional fertility preservation techniques so all cancer patients are able to have children after cancer.
We hope that these efforts will someday have the impact for cancer survivors that Dr. Yes, indeed is very interesting to study as a collage peer. Really love learning about this type of stuff if it is right and I sure do hope It is other wise I would be very disappointed.

In vitro fertilization IVF is an assisted reproductive technology ART initially introduced by Patrick Steptoe and Robert Edwards in the s to treat female infertility caused by damaged or blocked fallopian tubes. This major breakthrough in embryo research has provided large numbers of women the possibility of becoming pregnant, and subsequent advances have dramatically increased their chances.
Although the procedure was not successfully established until the last quarter of the twentieth century, the history behind the development of IVF dates back much further. Working with rabbit and guinea pig ova, Schenk noted that cell division occurred in cultures after sperm were added to ova.
The next milestone was in , when two scientists working independently, Colin Russell Austin in Australia and Min Chueh Chang in the United Sates, demonstrated that spermatozoa need to mature through certain stages before they develop the capacity to fertilize. By Chang was able to successfully use IVF to impregnate a rabbit.
Significant progress in developing a successful IVF technique with human embryos, however, would have to wait until the s. Patrick Steptoe , a practicing gynecologist at Oldam General Hospital who pioneered the use of laparoscopy in gynecology, teamed up with Edwards, a professor of human reproduction at Cambridge University , to try to achieve a successful pregnancy in humans using IVF.
Their collaboration started in when Edwards attended a lecture Steptoe gave on laparoscopy at the Royal Society of Medicine in London. They initially achieved successful fertilization and cell division of eggs in vitro in a petri dish with freshly extracted semen , but were unable to successfully implant the fertilized egg into the female uterus until Even before her mother was able to hold her newborn, Louise had undergone around 60 different tests to ensure she was "normal".
This is a far cry from modern procedures, which - owing much to the work of Bourn Hall in the s - follow a refined and well-established clinical process. Progress can also be seen in the modern use of ultrasound imaging to harvest the eggs under a mild sedation, rather than the form of keyhole surgery known as laparoscopy that was previously employed. Techniques developed in the late s also made a big difference in treating male infertility by injecting single sperm directly into the egg.
The chances of successfully conceiving through IVF decline with age, but the process is now more effective per cycle than natural reproduction.
It does not, however, have approval from all quarters. In November, Pope Francis said the process promoted children as "a right rather than a gift to welcome" and was "playing with life".
They were mostly positive, but there was some hate mail. It came with a threat that the people who sent it were coming to see them. Despite such isolated incidents, Louise - who conceived her two sons naturally - sees it as a privilege to have been the first person born through IVF.
