Cardiovascular disease, obesity, and type 2 diabetes in children born after assisted reproductive technology: A population-based cohort study
Norrman, Emma; Petzold, Max; Gissler, Mika; Spangmose, Anne Lærke; Opdahl, Signe; Henningsen, Anna-Karina; Pinborg, Anja; Tiitinen, Aila; Rosengren, Annika; Romundstad, Liv Bente; Wennerholm, Ulla-Britt; Bergh, Christina (Peer reviewed; Journal article, 2021)Background Some earlier studies have found indications of significant changes in cardiometabolic risk factors in children born after assisted reproductive technology (ART). Most of these studies are based on small cohorts ... -
The challenges of selective fertility and carryover effects in within-sibship analyses: the effect of assisted reproductive technology on perinatal mortality as an example
Westvik-Johari, Kjersti; Håberg, Siri Eldevik; Lawlor, Deborah A.; Romundstad, Liv Bente Bergem; Bergh, Christina; Wennerholm, Ulla-Britt; Gissler, Mika; Henningsen, Anna-Karina A.; Tiitinen, Aila; Pinborg, Anja; Opdahl, Signe (Peer reviewed; Journal article, 2023)Background Within-sibship analyses show lower perinatal mortality after assisted reproductive technology (ART) compared with natural conception (NC), a finding that appears biologically unlikely. We investigated whether ... -

Risk of Hypertensive Disorders in Pregnancy After Fresh and Frozen Embryo Transfer in Assisted Reproduction: A Population-Based Cohort Study With Within-Sibship Analysis
Petersen, Sindre Hoff; Westvik-Johari, Kjersti; Spangmose, Anne Lærke; Pinborg, Anja Bisgaard; Romundstad, Liv Bente Bergem; Bergh, Christina; Åsvold, Bjørn Olav; Gissler, Mika; Tiitinen, Aila; Wennerholm, Ulla-Britt; Opdahl, Signe (Peer reviewed; Journal article, 2022)Background: Frozen embryo transfer (frozen-ET) is increasingly common because of improved cryopreservation methods and elective freezing of all embryos. Frozen-ET is associated with higher risk of hypertensive disorders ... -
Risk of ovarian cancer in women who give birth after assisted reproductive technology (ART)—a registry-based Nordic cohort study with follow-up from first pregnancy
Sandvei, Marie Søfteland; Pinborg, Anja; Gissler, Mika; Bergh, Christina; Romundstad, Liv Bente Bergem; van Leeuwen, Flora E.; Spaan, Mandy; Tiitinen, Aila; Wennerholm, Ulla-Britt; Henningsen, Anna-Karina; Opdahl, Signe (Peer reviewed; Journal article, 2022)Background There is concern that assisted reproductive technology (ART) may increase ovarian cancer risk, but previous studies are inconclusive.
