As more and more researches are being made in the field of IVF, new trends are emerging. The procedure of IVF is becoming more and more popular day by day with increase in numbers of sterile women owing to new life style. Some of the problems associated with IVF have been premature delivery and low birth weight, multiple pregnancy and psychological problems on surrogate's children. Efforts are on going to solve these problems connected with this. Of these the former issue of lower weight and premature birth can be solved by adopting the freezing techniques of embryos rather than using fresh embryos says scientists. This has been brought to notice from a study presented at British Fertility Society during its Annual Meeting. There were suggestions to use frozen embryos rather than fresh ones from the year 2008. Research in this line is still going on and we shall come to a final opinion about this soon.
