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.
