Scientists came to the conclusion that the use of drugs in artificial fertilization (IVF) can lead to an increase in genetic abnormalities, and due to the birth of a sick child. This conclusion was made after counting the number of violations attributable to the egg before and after fertilization procedures.

He led the research professor, representing the London Centre of fertility, gynecology and genetics -Alan Handyside. The scientists of were discovered genetic disorders   instructed for the building cells, resulting meiosis, fission cells.

Since most human cells, excluding sex, there 46 chromosomes And during meiosis - a special method of cell division occurs reduction   (ie decrease) the initial amount of chromosomes exactly twice. As a result, each cell goes to a set of maternal chromosomes 23 and 23 - father.
Previously it was believed that during ovulation ovum, once a woman's body, defects occur in the chromosomes, but now turned out that deviations can appear after fertilization, meaning that they can be a cause of IVF .

In the process of cell division, there is a violation, ie added to chromosome . And it can threaten the birth of a child with severe genetic illnesses such as, for example, Edwards syndrome or Down's syndrome .

The risk, according to scientists, can cause high doses of follicle stimulating hormone (FSH), which is responsible for the maturation follicles   in the ovary. Doctors injected into the body synthetic FSH They wish to increase a woman's chances for successful pregnancy , But this leads to ovarian hyperstimulation, te «increase of their performance», and the appearance of of several ovules.
