Outcomes of pregnancies in women with hysteroscopically placed micro-inserts in situ

This was a retrospective review of all pregnancies reported after Essure in situ in the Netherlands. Pregnancies included those that were unintentional (resulting from lack of protocol adherence and/or misread confirmation tests) and those that were intentional (resulting from off-label use of Essure micro-inserts for hydrosalpinx closure before in vitro fertilization/intracytoplasmic sperm injection with embryo transfer or in vitro fertilization with embryo transfer after regret of sterilization). The outcomes of 50 pregnancies in women with 1 or 2 micro-inserts in situ were evaluated. Eight unintended pregnancies and 18 intended pregnancies resulted in birth of a full-term healthy baby. Seven infants were delivered via cesarean-section. Two women delivered prematurely by C-section, (singleton after 34 weeks 1 day, twins after 35 weeks 3 days). All babies are healthy and without any congenital anomalies. There were 2 stillbirths after 20 weeks; however, it is unlikely that this was related to the presence of the micro-inserts. In conclusion, it is unlikely that the presence of intratubal micro-inserts interferes with implantation and the developing amniotic sac and fetus.
