Interstitial Pregnancy after In Vitro Fertilization and Embryo Transfer Following Bilateral Salpingectomy:Report of Two Cases and Literature Review

Heterotopic Pregnancy after Assisted Reproductive Techniques

Heterotopic pregnancy (HP) is the simultaneous occurrence of intra- and extrauterine pregnancies. It is a rare event in spontaneous pregnancies with an incidence of less than 1:15000 however the frequency has increased to 1% in accordance with the widespread use of assisted reproductive techniques (ART). The pre-operative diagnosis of this condition is generally difficult and it would be life t...

O-32: Effects of Intrauterine Injection of Recombinant Human Chorionic Gonadotropin before Embryo Transfer on Outcome of In Vitro Fertilization/Intracytoplasmic Sperm Injection: A Randomized Clinical Trial

Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg i...

Does Transfer of Embryos at the Blastocyst Stage Increase the Risk of Multiple Pregnancy?

Prolonged in vitro cultivation allows us to obtain better quality embryos and provides better intrauterine conditions for transfer. The aim of this study was to compare the results of in vitro fertilisation (IVF) procedures in which 1, 2 or 3 blastocysts (group 1) were transferred with the results of IVF procedures in which 1, 2 or 3 embryos at the stage of 8 cells to morula, achieved under the...

Unilateral twin tubal pregnancy and subsequent heterotopic pregnancy in a patient following in vitro fertilization.

Unilateral twin tubal gestations are extremely rare with a reported incidence of 1 per 200 ectopic pregnancies. In recent years, the incidence of heterotopic pregnancy associated with in vitro fertilization and embryo transfer (IVF-ET) has risen to 1%-3% of achieved pregnancies. We report a very rare case of a 32-year-old woman with 6-year primary infertility with unilateral twin tubal pregnanc...
