Start of Pregnancy : Implantation or Conception
Pregnancy is generally defined as the beginning of the stage when the fertilized egg gets implanted in the uterus after almost a week of fertilization process. This is also stated by the American College of Obstetrics and Gynecology (ACOG), which is supposed to be one of the leading organization for this field of medicine.
Many in fact almost all of the doctors in the United States assume and believe that the pregnancy starts when the sperm actually fertilizes the egg. This was also shown as the result of a survey done in the United States based on finding the real cause and time of the pregnancy. This survey is possibly contradicting the position of a major and important medical group of people. It has an assumption and a view point that would possibly and potentially affect the United States policy and its laws pertaining to contraception and also pregnancy researches.

The American College of Obstetrics and Gynecology (ACOG), the leading name in this field of medicine also states and describes pregnancy as the start of the time when the egg is fertilized by the sperm and it gets implanted in the uterus. This happens almost a week after the fertilization.
Farr Curlin . a senior author involved in this study that featured in the American Journal of Obstetrics and Gynecology, and a professor at the University of Chicago ,also believes that the general public believes that the men of the medicine field have settled with this assumption of pregnancy. But its actually the men of the medicine field who seemed to disagree on this as per the survey revelations. Also on the basis of this study it was found that physicians who portray to be religious and opposed to abortion or any form of contraceptive measures which help prevent the implantation were also more likely to be the believers of the fact that conception is actually the main beginning of pregnancy. The stem cells obtained from the embryo which are used in vast scientific researches and are often obtained from extra embryos that are not transferred in a woman after the process of in vitrio fertilization.
Curlin and his colleagues made questionnaires for the survey and the main question remained the same in all. That was when the pregnancy actually starts, at conception or after implantation. Majority were of the opinion that pregnancy began at conception while about 28 per cent supported implantation. So a major lot of the doctors were disagreeable with the findings of the ACOG.
