What Causes Migraines in Males: Triggers and More

Migraines affect roughly 9% of men in the United States, about half the rate seen in women. That gap has led to decades of research focused primarily on female migraine patients, leaving many men without clear answers about why they get migraines and, in some cases, without effective treatment. The causes in men overlap significantly with general migraine triggers, but hormonal differences, sleep disorders, and even medication responses play out differently in male biology.

Estrogen Plays a Bigger Role Than Most Men Expect

When people think of hormonal migraines, they think of women. But estrogen matters for men too. Research from the American Academy of Neurology found that men with migraines had significantly higher estrogen levels between attacks: 97 picomoles per liter compared to 69 in men without migraines. Testosterone levels were similar in both groups, but because estrogen was elevated, the ratio of testosterone to estrogen was lower in migraine sufferers (3.9 versus 5.0 in men without migraines).

That ratio appears to be more important than either hormone alone. Men with migraines also reported symptoms consistent with a relative testosterone deficiency, including low mood, fatigue, low energy, and sexual dysfunction. Sixty-one percent of men with migraines reported these symptoms, compared to 27% of men without. Interestingly, testosterone levels actually spiked about 24 hours before a migraine in men who experienced warning signs like muscle stiffness, fatigue, and food cravings, suggesting hormonal fluctuation itself may be a trigger rather than a consistently low level.

Common Triggers That Hit Men Hard

Stress is the single most reported migraine trigger across both sexes, affecting nearly 70% of people with migraines. One study found that 50 to 70% of migraine patients had a direct, day-to-day link between stress levels and migraine activity. For men in high-pressure jobs or physically demanding work, this connection is worth paying attention to, because the trigger isn’t just emotional stress. Physical exertion, irregular schedules, and environmental exposures all count.

Dehydration triggers migraines in about a third of sufferers, and men who work outdoors, exercise heavily, or simply don’t prioritize water intake are particularly vulnerable. High humidity and heat compound this by increasing fluid loss.

Alcohol is another major trigger, and it’s not limited to red wine. While many migraine patients blame red wine specifically, research shows other types of alcohol trigger attacks just as often, and sometimes more frequently. Caffeine works both ways: regular consumption can set you up for withdrawal headaches, while sudden increases can trigger an attack on their own.

Other well-documented triggers include:

  • Irregular sleep schedules: Nearly half of all migraine attacks happen between 4:00 a.m. and 9:00 a.m., which suggests disrupted sleep architecture is involved, not just too little sleep.
  • Weather changes: Shifts in barometric pressure, storms, and excessive heat are common triggers.
  • Certain foods: Aged cheeses, cured meats, chocolate, artificial sweeteners, and foods high in histamine or MSG are frequent offenders.
  • Strong smells: Chemicals, gasoline, perfume, and cologne can activate nerve receptors in the nasal passages that either start a migraine or worsen one already underway.
  • Bright or flickering light: Both natural sunlight and fluorescent office lighting are problematic for many migraine patients.

Sleep Apnea and Migraine Overlap in Men

Sleep apnea is far more common in men than women, and it has a strong connection to migraines. A study presented at the American Academy of Neurology’s annual meeting found that 37% of migraine patients were at high risk for sleep apnea, though only about 10% had actually been diagnosed. Men with chronic migraines (15 or more headache days per month) were at especially high risk.

The overlap goes beyond just poor sleep. Migraine patients in the study reported snoring (about 33%), shortness of breath during sleep (21 to 30%), excessive daytime sleepiness (21 to 23%), and a general feeling that their sleep was inadequate (22 to 24%). These numbers were consistently worse in people with chronic migraine compared to episodic migraine. If you’re a man with frequent migraines who also snores heavily or wakes up feeling unrested, undiagnosed sleep apnea could be driving your attacks.

Genetics and Family History

Migraines run in families. The clearest genetic evidence comes from familial hemiplegic migraine, a rare subtype caused by mutations in specific genes that affect how nerve cells communicate. This form follows an autosomal dominant inheritance pattern, meaning you only need one copy of the altered gene from one parent to be affected. But even common migraines have a strong hereditary component. If one or both of your parents had migraines, your risk is substantially higher.

Migraine prevalence in men follows a distinctive two-peak pattern across a lifetime, with the first peak in the late teens and twenties, and a second peak around age 50. That second peak may reflect hormonal shifts that come with aging, including the gradual decline in testosterone and changes in the testosterone-to-estrogen ratio described above.

Medication Overuse Can Create a Cycle

One cause of worsening migraines that catches many men off guard is the very medication they take to treat them. Using acute migraine medication more than 10 days per month can itself trigger additional attacks, a pattern called medication overuse headache. This creates a frustrating cycle: more headaches lead to more medication, which leads to even more headaches. Men who tend to push through pain and then rely on heavy doses when they finally treat an attack may be especially prone to this pattern.

Standard Treatments May Work Differently in Men

One of the most important and underreported findings in migraine research is that newer migraine medications targeting a protein called CGRP may be significantly less effective in men. Pooled clinical trial data on two of these medications showed meaningful benefits in women but almost none in men. In women, freedom from pain after two hours was about 8% better than placebo; in men, the benefit was just 0.2%.

Preclinical research helps explain why. In animal studies, much lower doses of CGRP were needed to produce migraine-like pain in female animals compared to males, suggesting the CGRP pathway simply plays a smaller role in male migraines. The good news is that these medications have minimal side effects, so trying them isn’t risky. But men who don’t respond to CGRP-targeting treatments shouldn’t assume nothing will work. It may just mean their migraines operate through a different biological mechanism that responds better to other approaches.

Why Men Are Often Diagnosed Late

Men with migraines face a diagnostic delay of about five years on average between when symptoms start and when they receive a formal diagnosis. That’s roughly the same delay women experience (about six years), but the reasons differ. Men are less likely to seek medical help for headaches in the first place, and when they do, both patients and doctors may not consider migraine as a diagnosis because of the strong cultural association between migraines and women. The result is years of untreated or undertreated attacks.

The combination of hormonal factors that research is only beginning to understand, lifestyle triggers that are modifiable, and a possible need for different treatment strategies than women makes it especially important for men with recurring severe headaches to get a proper evaluation rather than writing off their symptoms.
