A population based evaluation of the mode of delivery in association with infertility treatment from 1990-2012.

Background: This study refers to population based data and investigates the development of the mode of delivery associated with infertility treatment over the last 23 years. Methods: All 1 202 557 deliveries in Hesse, Germany, between 1990 and 2012 were assessed. 2.2% of the study population, 26 761, had a delivery subsequent to infertility treatment based on the Hessian Perinatal Registry (HEPE). An evaluation in this subgroup was performed investigating the associations between the mode of delivery and the gestational week and the mother’s age. Results: A continuous and significant (p Discussion: The rate of cesarean section is continuously rising over the last 23 years with regard to parturients subsequent to infertility treatment. The CS rate is significantly higher compared to women with a spontaneous pregnancy and in comparison to the data from 20 years ago. Most recently, the number of CS (51,2%) exceeded the number of vaginal deliveries (48,8%) in Hesse subsequent to infertility treatment for the first time.
