"Existing trends, however, did not cause much surprise, as since the previous survey, in 2000, they have not changed," - said Dr Jacques de Mouzon of the hospital Bisetr (Bicetre) in Paris, along with colleagues presented in the journal Reproduction Rights "(Human Reproduction) 8th Report on the use of IE technologies, describing the practice and the results of IO throughout the world for 2002
Artificial insemination - a collective term for a range of technologies, including microinjection of sperm into the cytoplasm of the egg (ICSI), in vitro fertilization with embryo transfer or zygote (IVF, or IVF), the transfer of frozen embryos (FET), artificial insemination.
Compared with data for 2000, the number of cycles IO increased by about 25%, while the number of children who were born after OI, the world has increased from 219 thousand in 2000 to 246 thousand - in 2002.
In the period from 2000 to 2002. Despite a decrease in the average number of embryos transferred, almost 19% increased the number of births after IVF, 20% - after ICSI and 12% - after FET.
In many countries, there is a restriction on the transfer of more than two embryos per cycle IE, but in South Korea, Latin America, India and the UAE transfer rate 4 or more embryos remains high. Increase the frequency of multiple births, in turn, increased the proportion of stillbirths, premature births and deaths of newborns shortly after birth.
"The main problem of Io - high frequency of multiple births - remains in force - said Dr de Mouzon. - Part of it has decreased due to a restriction on the number of transferred embryos, but in some countries - is still great."
It raises questions and feasibility of more frequent use of ICSI, he added - "This technique can be successfully used for male infertility or failure of previous attempts at IVF, but in other cases - it turns unnecessarily high cost of the procedure and increases her risk, not giving any benefits in return.
