Key result
Assisted reproduction was not associated with an increased risk of venous (IRR 0.95; 95% CI 0.38-1.95) or arterial thrombosis (IRR 0.36; 95% CI 0.04-1.30) within 6 months.
Why the study?
Does assisted reproduction increase the risk of venous and arterial thrombosis in women?
Cohort (n=30,884)
Yes
Does assisted reproduction increase the risk of venous and arterial thrombosis in women?
Relative Risk: 0.95 (95% CI 0.38–1.95)
Assisted reproduction (IVF or ICSI) does not appear to increase the short-term risk of venous or arterial thrombosis in women without prior cardiovascular or malignant disease.
No takes yet. Share an insight, caveat, or question.
Supports reassuring short-term thrombotic safety for assisted reproduction in low-risk women; leaves open longer-term risks and effects in higher-risk groups.
Hansen et al. (2012) conducted a cohort in Infertility (n=30,884). Assisted reproduction (IVF or ICSI) vs. Young Danish women (previously published estimates) was evaluated on Venous thrombosis within 6 months (IRR 0.95, 95% CI 0.38-1.95). Assisted reproduction was not associated with an increased risk of venous (IRR 0.95; 95% CI 0.38-1.95) or arterial thrombosis (IRR 0.36; 95% CI 0.04-1.30) within 6 months.
