According to another research conducted by a team at St Olavs University Hospital, in Trondheim, it was found that there is a three-fold increase in the risk among mothers who had one normal pregnancy and a second one with assistance through IVF, or Intra Cytoplasmic Sperm Injection (ICSI). Placenta praevia result in haemorrhages in the mother, and also increases the risk of a premature delivery. According to this research it is for the first time that placenta praevia has been directly linked to the reproductive techniques says the lead researcher Dr Liv Bente Romundstad. But still the underlying mechanism causing the placenta praevia is not clear. The researchers are asking the fertility clinics to record the position of every transferred embryo. Dr Peter Bromwich, from the Care fertility clinic in Northampton said that it is high time that they start measuring and recording the position of transferred embryos. Dr Mark Hamilton, chairman of the British Fertility Society, said that everybody who wants to go in for an IVF treatment should discuss the issue with their gynaecologist in advance.
