With increasing knowledge and understanding of the natural world, including ourselves, we are now able to manage not only our environment but also our own biology, including including our reproduction. This not only has consequences for individuals but also for society and even the world in general. While many countries like Japan and Germany are worried about declining birth rates and aging populations, other countries like China and India are trying to increase lifespans. life expectancy of their population and reduce birth rates. While the majority of couples are turning to forms1 of contraception, more and more couples around the world are discovering that they are unable to conceive children naturally and are seeking medical help. What am I going to talk about? In the world, there are many couples who are unhappy and who fail to give birth to children, thus making them sterile. There are many different birth control methods that infertile parents can use to have a baby, but the one I'm going to talk about today is IVF: in vitro fertilization. There are currently hundreds of thousands of test tube babies in the world and this is a very popular method of having babies. According to the Centers for Disease Control (CDC), in 2002, about 2 percent, or 1.2 million of America's 62 million women, had a doctor's appointment related to infertility, and most of those appointments -you were for IVF. (Source: http://www.pbs.org/wgbh/americanexperience/features/general-article/babies-today/) IVF treatment was invented in order to grant infertile couples the happiness of having a child, however, it is when fertilization takes place outside the body. On average, 1 in 8 American couples suffer from infertility, and 1.1 million of them...... middle of paper ...... my. Families now have to pay for 2 children's clothing, 2 children's food, 2 children's education, and the costs only go up higher and higher. Conclusion: In conclusion, IVF treatment is a very effective and very reliable contraceptive. Many people around the world who are part of infertile couples have undergone this treatment and have had success. At present in the world, more than 190,000 babies have been born through IVF, and according to all the above information, IVF is a successful invention. It has no side effects or physical or mental risks. Overall, I think IVF treatment is worth it and should definitely be an option for infertile parents. I would also suggest using birth control pills, but IVF treatment is indeed an efficacy treatment..
