Why Women Have More Autoimmune Issues Than Men
SciShow・13 minutes read
The immune system is critical for fighting pathogens and preventing reinfections, but autoimmunity can lead to the immune system attacking the body's tissues, especially in women. Research into autoimmune conditions in women has been historically limited, but recent studies are exploring potential causes and treatments for these chronic and debilitating diseases.
Insights
- Autoimmune conditions predominantly affect women, with 75% of U.S. cases occurring in women, posing a significant scientific mystery.
- The X chromosome, with its immune system-related genes, is implicated in autoimmunity, potentially explaining why individuals with two X chromosomes are more prone to autoimmune issues.

Recent questions
What is autoimmunity and how does it affect the body?
Autoimmunity is a condition where the immune system mistakenly attacks the body's own tissues, leading to over 80 defined autoimmune conditions. This can result in chronic and debilitating diseases as the immune system targets healthy cells instead of pathogens.
Why do autoimmune conditions predominantly affect women?
Autoimmune conditions predominantly affect women, with 75% of cases in the U.S. occurring in women, posing a significant scientific mystery. Historically, these conditions have been understudied and not taken seriously by clinicians, hindering research progress into understanding why women are more susceptible to autoimmune issues compared to men.
What role do sex hormones play in autoimmune conditions?
Investigations into the role of sex hormones in autoimmune conditions have yielded mixed results on their impact. The X chromosome, which contains immune system-related genes, is implicated in autoimmunity, potentially explaining why individuals with two X chromosomes are more prone to autoimmune issues. Skewed X chromosome inactivation has also been linked to various autoimmune conditions, suggesting a potential treatment avenue.
How is autoimmunity linked to pregnancy?
The pregnancy compensation hypothesis proposes that the decline in pregnancies may be linked to the rise in autoimmune conditions, indicating a potential evolutionary connection between pregnancy and autoimmunity. Science offers potential treatments beyond pregnancy for reaping immune benefits, such as mimicking pregnancy's molecular pathways to address autoimmune issues.
What are potential treatments for autoimmune conditions?
Science offers potential treatments beyond pregnancy for reaping immune benefits, such as mimicking pregnancy's molecular pathways. While the reasons behind women's increased susceptibility to autoimmune conditions compared to men remain unclear, ongoing investigations aim to unravel this complex issue and develop effective treatments for autoimmune conditions.
