A scoping review examined over 1,000 studies on sex and gender differences in obsessive-compulsive disorder (OCD). The review found that while there is a large amount of research on this topic, the findings have not been well integrated. This means that clear conclusions about how OCD affects males and females differently are still lacking.
The review included 72 meta-analyses, 19 systematic reviews, and many other studies. It looked at areas like symptoms, how common OCD is, genetics, brain function, treatments, and animal models. Despite the large number of studies, the authors noted that there is limited synthesis of the evidence, making it hard to draw firm conclusions.
One major issue is that researchers measure sex and gender inconsistently. They also often fail to account for menstrual cycle effects, which can influence symptoms in women. Additionally, many studies do not consider differences in insight, help-seeking behavior, or other conditions that often occur with OCD.
The review suggests that future research should focus on these gaps. It proposes that better understanding sex and gender differences could lead to more personalized and effective treatments. For example, treatments might be tailored to the specific needs of men and women, improving mental health care for everyone.
However, the review does not provide definitive clinical guidelines. Instead, it highlights areas where more research is needed. The authors emphasize that this is a starting point for future studies, not a final answer.
