Pain differences between men and women: understanding of the immune system, hormones, and chronic pain
Pain in the human body is not just a sensation but a complex biological message. It warns us that there is injury, inflammation, or internal damage in some part of the body. But the question is, do men and women feel pain in the same way? Do the intensity of pain and the recovery process from it differ in both? Modern scientific research has made very important discoveries on this subject that open new avenues not only in behavioral health but also in the fields of immunology, neuroscience, and endocrinology. A recently published study conducted by researchers at Michigan State University and published in the renowned scientific journal Science Immunology made it clear that the immune system of men is capable of eliminating pain relatively quickly in certain situations. This discovery could play an important role in understanding the growing problem of chronic pain, especially in the context that the rate of chronic pain has been observed to be higher in women.
The difference in pain between men and women is due to biological foundations
The biological mechanism of pain: the contribution of nerves and immune cells
Traditionally, pain was thought to be a matter of the nervous system. When the body is injured, nerve cells (neurons) transmit pain signals to the brain, and we feel them. But modern research has shown that the immune system also plays an active role in this process.
Special immune cells in the body, called monocytes, are involved in the inflammation and healing process. Research has shown that a specific type of these monocytes produces an anti-inflammatory protein called interleukin-10 (IL-10). This protein tells nerve cells to turn off pain signals, thus reducing pain.
This discovery is important because it has led to the view that pain is not just a neurological problem but an “immune-neural interaction.”
Faster pain recovery in men: The role of testosterone
The study found that injured male mice had a higher number of IL-10-producing monocytes than female mice. As a result, pain in men subsided relatively quickly after injury.
When the researchers gave female mice testosterone, their IL-10 levels increased and pain recovery accelerated. Conversely, when testosterone was reduced in male mice, IL-10 levels decreased and pain persisted for a longer period.
These results indicate that the male sex hormone testosterone stimulates immune cells to increase the production of pain-relieving proteins.
There is also an important psychological aspect here. In many societies, there is a perception that men are more tolerant of pain or that women are more sensitive. But this study makes it clear that the roots of this difference may not be simply psychological but also biological.
Human study: Evidence from 245 patients
The research was not limited to animals. Data from 245 human patients recovering from injury were also reviewed. The results confirmed the animal study. Male patients experienced relatively faster pain relief and had higher levels of IL-10 and monocytes.
This made it clear that this phenomenon was not just a laboratory result but could also be observed in real human conditions.
Why is chronic pain more common in women?
Chronic pain is a condition that persists for three months or more. Migraines, fibromyalgia, arthritis, and other pain conditions are more common in women worldwide.
If women have relatively low IL-10 production and slower pain resolution, the risk of transient pain turning into chronic pain may be increased. This does not mean that women are “weaker,” but rather that their immune response works differently.
This difference is also important for behavioral health because chronic pain affects not only physical but also mental health. Long-term pain can lead to depression, anxiety, and sleep disorders.
Pain, mental health and behavioral science
In behavioral health, pain is considered a multifaceted experience. It involves biological, psychological, and social factors. If a person experiences pain for a long time, their thinking, emotions, and behaviors are affected.
In people with chronic pain:
Feelings of hopelessness and helplessness may increase
Social activities may decrease
Work performance may be affected
Sleep quality may be impaired
When we understand pain at the immune and hormonal levels, we also understand that treatment should not be limited to painkillers alone but requires a comprehensive strategy.
New hope for non-opioid treatments
Opioid medications have traditionally been used to treat severe pain, but their side effects and risk of addiction have become a global problem. New research suggests that if IL-10 production can be safely increased, pain can be reduced naturally.
This approach represents a fundamental shift in pain treatment:
Rather than suppressing pain, enhancing its natural biological response.
In the future, drugs could be developed that specifically activate immune cells to increase the production of anti-inflammatory proteins and stop pain before it becomes chronic.
Why is it important to understand gender differences?
For a long time, men were used as the “standard model” in medical research, which led to the neglect of women’s specific biological needs. However, gender-based research is now gaining importance.
In the treatment of pain, it is important to understand that:
Men and women may have different immune responses
Hormonal changes (such as menstruation, pregnancy, or menopause) may affect pain
Response to treatment may differ
This distinction becomes even more important in the context of behavioral health because the experience of pain is not only physical but also emotional and social.
Hormones, immunity and behavior: An integrated system
Testosterone is often associated with aggression or masculinity, but this study highlights another positive aspect of it. This hormone can help relieve pain by activating immune cells.
In women, estrogen and other hormones also affect the immune system. Hormonal fluctuations can sometimes affect inflammation and the severity of pain.
Practical tips for behavioral health
Although this research focuses on the biological level, its practical implications are also significant in behavioral health:
Chronic pain needs to be taken seriously, especially in women.
It is scientifically inaccurate to label pain as a “mental illness.”
Treatment plans should take gender differences into account.
Mental health support (counseling, CBT, etc.) can be helpful in managing pain.
Lifestyle changes such as a balanced diet, adequate sleep, and regular exercise can strengthen the immune system.
Conclusion: The New Scientific Story of Pain
Pain is a fundamental part of the human experience, but its intensity and duration vary from person to person. Recent research has revealed that there is a strong biological basis for the differences in pain between men and women, in which immune cells, the IL-10 protein, and testosterone play important roles.
This discovery not only helps us understand chronic pain but also opens up new avenues for non-opioid treatments. The message in the field of behavioral health is clear: pain should be considered not just a physical symptom but a complete biological and psychological experience.
When we acknowledge the immune and hormonal factors behind pain, we move toward more compassionate, scientific, and effective treatments that take into account both the individual’s biology and mental state.
