IVF is beneficial for patients who would be unable to conceive; those with blocked tubes, a low ovarian reserve, male infertility, unexplained infertility, polycystic ovary syndrome (PCOS), Endometriosis, and menopause. It also helps single women and same sex couples, who want children but aren't in the optimal situation to have any, and helps with the diagnosis of fertilization problems. The ultimate advantage is achieving a successful and healthy baby. IVF is more successful than IUI and other assisted reproductive technology; its success rates have increased every single year due to the technological advances being made.
When looking at IVF of course it is seen as a positive alternative for parents, but there is no consideration for babies who are born from the IVF system. This is a fairly new system and is currently at a 25% rate of success in parents who are trying to have a baby ("The Pros and Cons of IVF." Arizona PBS. PBS, n.d. Web. 27 Apr. 2016.) You previously mentioned why females with disorders in their reproductive system tend to seek this, well IVF has in many cases left a healthy woman with ovarian hyper-stimulation syndrome ( "The Pros and Cons of IVF." Arizona PBS. PBS, n.d. Web. 27 Apr. 2016.).
The IVF system has been around for over 35 years and has created 5 million babies; meaning that this has positively impacted 5 million family lives. (Brian, "The Guardian", 2013) Although the IVF cycle may be unsuccessful, there is a possibility of something going wrong in all things that we do. IVF varies from woman to woman, and a fertility specialist can give more insight into the likelihood of success. ("The UK's Pioneering Fertility Clinics", 2014) The use of fewer or no drugs in natural and mild IVF cycles means small likelihood of developing side effects, along with more babies being born at full term and a higher birth weight. Fertility clinics should have single embryo transfer policies to avoid the risk of a multiple pregnancy and those that are considering the process should plan out costs and financing. There are also options for low-cost treatment, such as egg sharing. ("The UK's Pioneering Fertility Clinics", 2014)
Like i said, and thank you for supporting my argument. 35 years is fairly new and there has not been enough times to watch the full lives of these IVF born children to see what affects they show in older age. In IVF treatments, there is often more than one embryo put back into the uterus, and this leads to a higher likelihood of multiple pregnancy; around 20-30% of IVF pregnancies are multiple pregnancies. Multiple pregnancies do carry associated health risks to mother and baby: there is an increased chance of premature labor, miscarriage, stillbirth and infant health problems with multiple pregnancies. So the statement that only a single embryo is implanted is false. ("The Pros and Cons of IVF." Arizona PBS. PBS, n.d. Web. 27 Apr. 2016.) The idea of selecting some embryos and potentially discarding others may not sit well with everybody. This raises the ethical issue that playing god shouldn't be allowed or given to a certain individual.
Researchers wouldn't allow for the IVF process to be available if they were extremely worried about the future risks for those born children. They are continuously checking up on those that had come from IVF and finding new ways to prevent/protect the mothers and the children. The first IVF child may have been born in 1978 but studies were conducted in previous years. It's known that animal research can give insight into human effects and there had been experiments on mice; which allowed data to be collected that gives us a look into what people can expect from IVF. (Massy-Beresford, "The Guardian", 2014) Also, I never stated that a single embryo is implanted. I had said that fertility clinics should have single embryo transfer policies; meaning that some do allow for one embryo to be placed inside the uterus, if wanting to significantly decrease the chances of a multiple pregnancy. ("The UK's Pioneering Fertility Clinics", 2014) There have been improvements in the techniques and success rates have increased with the transferring fewer embryos, making it a more common process. (Massy-Beresford, "The Guardian", 2014) Genetic screening of embryos is beneficial. Preimplantation genetic screening (PGS) is the removal of one or more cells from an IVF embryo to test DNA normalcy. This screens for chromosome number, so it can detect any disease that has an extra or missing chromosome. The actual chromosomal abnormalities are what cause 50% of the IVF failure implantation and 70% of miscarriages. ("PGS") Therefore IVF can be helpful in preventing miscarriages and implantation failure.
