Researchers propose artificially slowing down cell division to limit aneuploidy, offering a potential solution for improving egg quality in older patients.
A study found that combined drinking and smoking after the first trimester may be associated with a significantly increased risk of late stillbirth. The observational study suggests that this exposure may be particularly concerning for women who do not have pre-existing health conditions.
A Stanford University study suggests that wildfire smoke exposure during pregnancy increases the risk of preterm birth, with as many as 7,000 extra births attributed to this factor between 2007 and 2012. The research highlights the need for investment in prescribed burns, mechanical thinning, or other efforts to reduce extreme wildfires.
