New research suggests marijuana use may reduce fertility and raise miscarriage risk.
A new study has found the first direct evidence that cannabis use can cause chromosome errors in human embryos, with women who had detectable THC levels showing a 9 percent increase in genetically abnormal embryos during fertility treatments.
The research, published in Nature Communications, analyzed more than 1,000 women undergoing in vitro fertilization (IVF) treatment and provides insights into how marijuana affects female fertility at the cellular level as cannabis use among women of reproductive age continues to rise.
