Assisted reproduction technologies and ovulation induction for treatment of infertility continue to cause high order multiple gestations. Increased perinatal morbidity and mortality, as well as maternal morbidity, may complicate these pregnancies. Selective fetal reduction, an acceptable therapeutic approach in these cases, is usually performed at or after the ninth week of gestation, with KCl injected in the vicinity of the fetal heart, and is associated with a total pregnancy loss rate of 11.7%. We report our experience with 90 women who underwent early (mean 7.5 weeks gestation, range 7. 0-8.0 weeks) transvaginal selective embryo aspiration. The mean number of viable embryos before and after reduction was 3.5 and 2.1 respectively. Six (6.7%) pregnancies were lost before 24 gestational weeks. One miscarriage occurred at the tenth gestational week. The other five pregnancies were aborted at 17.3-21.6 weeks gestation. Additional interventions were performed in three of these pregnancies: genetic amniocentesis in two cases and cervical suture in one case. In the subset of 39 patients with>/=4 embryos, only one (2.6%) pregnancy loss was recorded. This loss rate is significantly lower (P < 0.05) than the 15.3% loss rate in patients with >/=4 fetuses calculated from other work. Four (4.4%) other pregnancies were complicated by premature delivery (25-28 weeks gestation). Mean gestational age of delivered pregnancies in our series was 35.7 weeks. In conclusion, early transvaginal embryo aspiration is a simple and relatively safe method for multiple pregnancy reduction. The overall pregnancy loss rate associated with early embryo aspiration is similar to that of procedures performed at later gestational age, but is significantly lower when the initial number of embryos is four or greater.
