Triplet pregnancy and fetal reduction counselling.
The aim of this study was to compare the fetal loss between triplet pregnancies that underwent fetal reduction to twins and triplets which continued in spite of reduction being suggested to all of them. During a five year period a total of 3,518 cycles underwent ovarian stimulation with GnRH analogues, HMG, pure-FSH and HCG for the purpose of IVF; 2,918 women underwent ovarian aspiration leading to 2,380 embryotransfers. A total of 560 clinical pregnancies were detected with 24 clinical triplet pregnancies. Fourteen women continued their triplet pregnancy while 10 women underwent fetal reduction to twins. From 42 fetuses (14 triplets) starting the third trimester only 29 survived (total fetal loss 30.9%). From 14 fetuses (7 twins) starting the third trimester all survived. Three twins were lost during the second trimester due to cervix incompetence. Fetal reduction to twins must be proposed to each multifetal pregnancy, considering the very serious high mortality rate.
