Abstract:

Spain is the fourth country in Europe in terms of multiple twin pregnancies. We are witnessing an important increment in the number of twin pregnancies directly related to advanced maternal age and assisted reproductive techniques (Figure 1).1,2The likelihood of having an spontaneous twin pregnancy is 2%, and it increases to 25% with assisted reproductive techniques.2 Spain is the third European country with the largest number of treatments of fertility behind France and Germany, which contributes to the increase in multiple gestations. 80,000 fertility treatments are performed according to data from the Spanish Society of Fertility (SEF). In case of in-vitro fertilization treatments, the transfer of two or more embryos resulted in 92,7% in the year 2012.2 Therefore, Spanish patients prefer to transfer two or more embryos in order to increase the chance of success. Currently in our country the Assisted Reproduction Law does not allow transferring more than three embryos at a time, and recommends not more than two. Three embryo will only be transferred as a secondary option when the woman has not achieved pregnancy in at least two previous cycles..........
