Highlights in assessing age embryos

Even if the known value of the embryo preformed in the germ cells from which the embryo is formed, it running like new individual occurs after conception. Age after insemination, the embryo homo sapiens, caught in the laboratory for the study, in fact rarely pre-installed, except the most indicative evidence. Even if the fruit is accompanied by the most detailed research materials, announcements, in most cases based solely on trying to think of the patient factors own sexuality. If we assume that the information about the time of the last menstrual period marked in the diary, but it is unknown what the sexual period, when women were given ovulation. If comprehensiveness motivation we assume that time of ovulation and possibly mating, which was successful, determined, and even then we are able to find a watch insemination with certainty from half a day to a day. If the fetus with such unusually detailed message about the history of the origin obtained as a result of spontaneous termination of pregnancy, however, obscure the time of its destruction. We do not have symptoms for judgments about, for what period of time before the birth interrupted its growth and death has come. Judging by the body of the embryo stage of resorption, which sometimes can be seen in lessons chorionic vesicles, it is indisputable that the time between the death of the embryo and a miscarriage can be significant. Designated interval is not changed, in order to be able to spend the most correct estimate of their duration in each case. In top condition embryos recovered during medical procedures. When normal growing embryo separated by a surgical procedure, we have the knowledge uniqueness least the time of his death.

All of the above highlights the increased value of the collection as possible especially given reports on the development of the embryo in every situation where the process of intrauterine pregnancy was necessary to stop by surgery, and proves the weight of collecting such information on the development of the embryo, along with carefully savings embryo for research in the laboratory, where fetus will be measured, and then studied by other methods, the right to determine the stage of its development. Only when working through all of these materials can increase the accuracy of our data on the facts that occur during fetal life.

Theory of the formation of the twin monsters

We seem to know much better the factors that contribute to the formation of the twin monsters than most other causes of developmental disorders. Obviously, we are dealing here with the wrong education takes place between identical twins. As we have seen, the indirect evidence obtained in lower animals show that this type of education a person has twins must be connected to either the division of a growing group of undifferentiated cells in the early stage of the bubble blast derma.
