Multiple pregnancies arising from assisted reproduction are known to be associated with increased medical, psychological, economical and social risks. If only two embryos develop after culture, how should the couple be counselled in relation to the risk of multiple pregnancy? We performed a retrospective review of all IVF/ICSI treatments performed between 1 January 2005 and 31 December 2007, that resulted in double embryos transfer (DET). We identified 623 cycles with a fortuitous DET (Group I) and 635 cycles with an elective DET (Group II). Group II were significantly more likely to have twins when compared with Group I, irrespective of age. Twin rates in Group I were higher in IVF compared with ICSI; 33.3% vs 16.6% in < 35 years old and 16.2% vs 7.6% in 35-40 years old. Therefore, single embryo transfer should be considered for IVF patients below 35 years old, even if only two good quality embryos are available.Item Type
