Chronic illness and chronic pain can have profound negative effects on relationship and sexual satisfaction, yet the influence of migraine on sexuality has not been previously evaluated. To assess sexual functions in subjects with migraine compared to those with no migraine. We evaluated female university students using the Israeli sexual behavior inventory (ISBI). Migraine was diagnosed according to self-reported symptoms according to the IHS criteria. Several dimensions of female sexuality—desire, orgasm, sexual avoidance, interpersonal sexual relationship, health influence, satisfaction and pain were evaluated using a structured questionnaire. Thirty-three (23.9%) of the participants met the IHS criteria for episodic migraine with and without aura. Sexual activity, desire, orgasm and satisfaction from sexual life did not differ significantly between migraine sufferers and non-sufferers. Migraine patients reported lower ISBI scores, higher health influence on sexual life, higher levels of sexual pain and lower sexual satisfaction. Migraine negatively affected the sexual life of sufferers. Sexual pain disorder is more common among migraine sufferers compared to non-migraineurs.
Chronic illness  and chronic pain  can have profound negative effects on relationship and sexual satisfaction of both patients and partners. The effects of chronic illness on sexuality are multifactorial and have an impact on all phases of sexual response. Sexual desire, arousal and activity may be altered by illness through interference with the hormonal, vascular and neural integrity of the mind and the genitalia, as well as the effects and side effects of medications. Anxiety, fear, loss of self-esteem, grief and depression are strongly associated with chronic illness and may also impair sexual function.
Studies examining  the prevalence of sexual dysfunction, and the role of psychological variables, including quality of life, on sexual activity in patients with non-cancer pain found that sexual dysfunction was common, and more frequently reported by those with greater disability and depression, shorter pain duration, and infrequent use of coping self-statements.
Although sexual dysfunction was commonly reported, subjects perceived it had less importance in quality of life than did other factors possibly because of adaptation to the impact of chronic illness on sexual function.
Migraine is an extremely prevalent disease: The lifetime prevalence of migraine in women is 33% and the 1-year prevalence of migraine in women is 25%. In men, the lifetime prevalence is 13.3% and the 1-year prevalence is 7.5%. It is a chronic—episodic disease, most common in men and women between the ages of 15–55 years that can impair many aspects of life . Still, its influence on sexuality has not yet been systematically evaluated. The aim of the present study was to compare the prevalence of sexual dysfunctions between the migraine sufferers and non-sufferers participants.
In the present cross-sectional study, we evaluated female students from the Ben-Gurion University of the Negev who agreed to participate in the study. All the participants were included after having received a detailed explanation on the purpose and design of the study. Previously published data or the researchers assumptions regarding pain and sexual function were not presented to the participants. The study was approved by the institutional ethical committee.
Female students were recruited from classrooms, in which a brief presentation of the study was given. Subjects who were pregnant, were not sexually active during the year prior to questionnaire administration, and subjects who suffered from any neurological disorder (other than headache) or sustained a head trauma during the last year, were excluded from the study.
Demographicsand background: Participants were asked to answer questions regarding their personal background (e.g., age, marital status, religion, extent of religious observance, height, weight etc.).
Headache history: The participants were asked to report whether they suffered from troubling headache and if so, to report headache characteristics and accompanying features, using a list of items (frequency, number of headache days/month, severity, aura symptoms, localization, quality, exacerbating factors, nausea, vomiting, sensitivity to light and sound, triggers etc.). Migraine diagnosis was based on the 2004 IHS criteria for migraine with and without aura .
Migraine disability assessment scale(MIDAS): The migraine disability assessment (MIDAS) scale was used to quantify headache-related disability . MIDAS is a brief and reliable headache-specific tool, which captures headache-related disability. It consists of five questions relating to the influence of headache on everyday activities over the preceding 3 months.
The Israeli sexual behavior inventory(ISBI): The ISBI is a 33 items questionnaire which was primarily designed to assess the impact of sexual problems, chronic illness and disability on sexual functioning and experience .
This instrument was proved to be a reliable and valid self-report measure of sexual behavior.
Analysis was performed using SPSS Win (version13.0) software. The socio demographic and health related characteristics were presented as proportion for categorical variables and mean with standard deviation for continuous variables. The ISBI questions were mapped on the scale from 1 to 5 as the higher grade signed the lower dysfunction. The ISBI questions were combined into domains and the score for each domain was calculated as the sum of related questions grades. The socio demographic and health related characteristics were compared between the migraine sufferers and non-sufferers participants using Chi square test, Fisher’s exact test and Student’s t test. The relationships between sexual behavior items, and migraine were examined using Mann–Whitney non-parametric test due to the small sample size in subgroups and discrete nature of the ISBI scores. The multivariable analysis for sexual behavior based on linear regression. A p values of <0.05 (two tail) were defined as significant.
Out of 172 candidates, 138 (about 80%) agreed to participate in the study. Eleven subjects (7.9%) met the exclusion criteria due to sexual inactivity during the last year. The rest, 127 participants were included into the study. The median age of the subjects was 25 years. Most of them were unmarried, but had a regular sexual partner. In addition, most of them were secular, heterosexual and used oral contraception.

The severity of migraine, as reflected by the MIDAS score, was found to be correlated to lower scores in the health domain (rs = 0.404; p = 0.024). It was not associated with other domains of the score or with the total ISBI score.
Female sexual dysfunction  is a general term used for various disorders of the sexual process in women affecting the various segments of the sexual response cycle: desire, arousal, orgasm and resolution. Inability or difficulty to enjoy any of these stages can interfere with sexual satisfaction and cause some degree of dysfunction. Female sexual dysfunctions can be accordingly subdivided in the DSM IV into desire, arousal, orgasmic and sexual pain disorders.
In the presented study, we attempted to evaluate sexual function and dysfunction among young women suffering from migraine compared to non-migraine sufferers, using the ISBI.
Sexual desire, orgasm and sexual interpersonal relations were similar among migraineurs compared to non-migraineurs, and where comparable to previous reports regarding Israeli women in this age group. Unlike a recent study , we did not find migraine patients to have higher degrees of sexual desire. Three domains were significantly impaired among migraine sufferers: health influence, sexual pain and satisfaction. Positive answers regarding fear of sex and avoidance of sexual intercourse were more prevalent among migraine patients.
As in other chronic pain conditions, health influence on sexual life is expected among migraine patients. Indeed its influence, reflected by higher scores in this domain, was found to be correlated with higher MIDAS scores.
It seems reasonable, that avoidance, fear of penetration and consequently lower satisfaction are associated with higher levels of sexually associated pain.
Sexual pain disorders [8, 10] fall into one of two categories: dyspareunia and vaginismus. Dyspareunia is genital pain experienced during or immediately after sexual intercourse. Vaginismus is the recurrent or persistent involuntary or subconscious voluntary spasm (or contraction) of the genital perineal muscles that surround the outer third of the vagina when the insertion of any object is attempted. Dyspareunia is estimated to affect 5–15% of women annually, according to the National Health and Social Life Survey, and vaginismus affects 15–17% of women presenting to a sex therapy clinic [8, 10, 11]. Our study questionnaire was not designed to evaluate the various aspects of sexual pain disorder, and this subject should be addressed in future studies.
A possible explanation for the high prevalence of sexual pain disorder among migraine females is sensitization of pain pathways [10, 12] often found in migraine patients (either as a cause or consequence). Clinical and experimental observations  on migraine suggest that a general hyper excitability could develop along nociceptive trigeminal neurons allowing the activation of descending pathways that facilitate pain processing or the suppression of pathways that slow down pain transmission. Slowly progressive dysfunction of central pain systems secondary to the repetition of attacks of the originating headache has been implicated in transforming the process from an episodic to a chronic condition. This concept of an irritable focus in the central nervous system is currently known as “central sensitization” and is a characteristic feature of visceral pain. Dyspareunia was found to be a co-morbid phenomenon with other pain syndromes [10, 11] (e.g. fibromyalgia), and to involve increased sensitivity to pain and touch . These findings support the involvement of central sensitization in patients with sexual pain disorder.
It is also possible that migraineurs tend to be more attentive to somatic and pain symptoms.
Recurrent pain is often characterized by elevated pain-related fear and avoidance of behaviors which the headache sufferer believe will initiate or perpetuate the headache pain, a maladaptive process which serves to promote pain related disability . This process might be the underlying reason for the increased fear of sexual intercourse and penetration among migraine patients in this study.
The present study was designed as a pilot study, exploring different aspects of female sexuality in migraine sufferers and non-sufferers. To avoid bias, the study was conducted in the community, and randomly selected the participating women. Female students were divided into migraine sufferers and non-sufferers. The evaluated population is not representative of the general population, but rather a homogenous population of young, educated, secular women belonging to a relatively high socioeconomic status. One has to take into account that only in such a population asking intimate sexual questions, and getting honest answers; is feasible. Compared to Israeli women in similar age group [6, 7], our study population reported higher sexual desire, tended more to initiate sexual intercourse with their partner, and lower fear of intercourse and penetration. The interpretation of the findings should therefore be limited to this group of women only.
As the respondents were asked to report about only troubling headaches, only a small number of subjects reported headaches corresponding to IHS criteria of tension type headache. No information regarding tension headache can be concluded from this study and further investigation is required. Therefore, no conclusions can be drawn from the current study regarding patients with this type of headache.
Despite these limitations, our findings suggest that migraine affects the sexual life of women suffering from it. This effect is both severity dependent (as represented by the health influence domain) and independent (intercourse associated pain).
Future studies should be directed in exploring the incidence of sexual dysfunction in general and specifically sexual pain disorders in other migraine suffering populations, and in evaluating the exact nature of the sexual pain disorders. Findings of such studies may help in improving sexual related quality of life.
