This editorial discusses the importance of including women in medical research trials. It notes that women have historically been excluded from many studies due to concerns about potential risks to pregnancy. However, this means that little is known about how drugs and other treatments affect women. The editorial argues that women of childbearing age should not be excluded from research altogether, but that special informed consent is needed to discuss any potential risks to pregnancy. Researchers must make efforts to minimize gender bias and ensure women are represented in both the design and participation of medical studies.
