Research on aspirin's role in preventing various health issues has yielded mixed findings, with some studies suggesting its potential benefits in pregnancy and cardiovascular health, while others advise against its use for primary prevention in older adults or for cancer prevention. The effectiveness of aspirin in preventing adverse outcomes in twin pregnancies conceived using assisted reproductive technology is also being explored. The use of aspirin is being compared to other treatments, such as GLP-1 receptor agonists, in reducing certain health risks.
