    Tubal factor infertility with prior ectopic pregnancy: a double whammy? A retrospective cohort study of 2,892 women. Cai He,Mol Ben W,Li Ping,Liu Xitong,Watrelot Antoine,Shi Juanzi Fertility and sterility OBJECTIVE:To investigate the impact of a history of previous naturally conceived tubal ectopic pregnancy (TEP) on subsequent IVF/intracytoplasmic sperm injection (ICSI) pregnancy and perinatal outcomes. DESIGN:Retrospective cohort study. SETTING:Reproductive medicine center in a tertiary hospital. PATIENT(S):A total of 2,892 women with tubal infertility undergoing the first fresh IVF/ICSI cycle. INTERVENTION(S):Women were stratified into three groups according to the type of previous naturally conceived pregnancy: TEP, intrauterine pregnancy (IUP), and no pregnancy. MAIN OUTCOMES MEASURE(S):Pregnancy and neonatal outcomes were analyzed for each cohort and stratified into the following categories based on female age: <30 years, 30-35 years, and ≥35 years. RESULT(S):Of the 2,892 patients with tubal factor infertility, 511 (17.7%) women had a history of TEP, 1,044 (36.1%) had prior IUP, and 1,337 (46.2%) had never been pregnant. Couples with an initial TEP tended to be younger and had experienced a shorter duration of infertility. Across the whole cohort, the optimal live birth rate decreased in older age groups. Live birth rates stratified by maternal age (<30, 30-35, ≥35 years) did not differ between the TEP group (59.9%, 53.7%, 45.5%) and the IUP (62.0%, 53.8%, 40.6%) and no pregnancy group (56.7%, 54.4%, 45.6%). This did not change after adjusting for confounders such as age and years of infertility. Previous treatment of TEP with salpingectomy, salpingostomy, or medical treatment did not significantly affect subsequent fertility outcomes. The rates of preterm and low birth weight after TEP were also not significantly higher than in women with a previous IUP. CONCLUSION(S):Fertility history, including previous TEP, does not influence the probability of live birth after IVF/ICSI in women with tubal factor infertility. 10.1016/j.fertnstert.2019.12.036
