Zusammenfassung:Abstract STUDY QUESTION Does in vitro fertilization (IVF) affect the course of anxiety and depressive symptoms as well as physiological stress from pregnancy to postpartum period? SUMMARY ANSWER IVF mothers have more anxiety symptoms and higher stress biomarker levels but fewer depression symptoms than natural conception mothers at the third trimester of pregnancy, but these differences are negligible during postpartum period. WHAT IS KNOWN ALREADY Cross-sectional studies have found an association between IVF and high stress levels during the prenatal period. There is, however, no follow-up study about the IVF effect on the mental health status from pregnancy to postpartum, adopting simultaneous measurement of self-reported symptoms and stress biomarkers. STUDY DESIGN, SIZE, DURATION This is a prospective cohort study. A total of 243 eligible women were recruited during the third trimester of pregnancy (60 women after successful IVF and 183 who conceived naturally). The recruitment was performed during a 12-month period, and the follow-up was carried out until 3 months after delivery. PARTICIPANTS/MATERIALS, SETTING, METHODS This study was performed in the Division of Obstetrics in a regional referral center. The State scale of the State-Trait Anxiety Inventory (STAI-S) and the Beck Depression Inventory-Sort Form (BDI/SF) were used as anxiety and depression indicators, respectively; salivary cortisol and α-amylase levels as stress biomarkers. Anxiety, depression and stress biomarkers were measured at the third trimester of pregnancy (T1), at 48 h after birth (T2) and at 3 months after birth (T3). Associations with IVF were assessed using ordinal mixed models for anxiety and depressive symptoms and linear quantile models for stress biomarkers. MAIN RESULTS AND THE ROLE OF CHANCE Relative to natural conception mothers, IVF mothers had higher STAI-S scores at T1 (P = 0.016, odds ratio (OR) = 2.46), and this difference remained steady from T1 to T2 (P = 0.37, OR = 0.70) and from T2 to T3 (P = 0.36, OR = 0.69). In the case of depressive symptoms, the IVF group obtained lower BDI/SF scores at T1 (P < 0.001, OR = 0.192). This difference was apparently reduced from T1 to T2 (P = 0.072, OR = 2.21) and remained constant from T2 to T3 (P = 0.107, OR = 2.09). It is important to note that whereas the mean BDI/SF score was not clinically significant for any group (it was lower than the cut-off 4), the mean STAI-S score of the IVF group at T1 was so (it was higher than t
