How does ADHD affect sexual function?

This systematic review of the literature identified seven studies addressing ADHD and sexuality.

Sexual function

A Dutch study compared 136 persons with ADHD with two large surveys of the general Dutch population. They used both a self-report questionnaire, the Questionnaire for screening Sexual Dysfunction and a non-validated questionnaire especially constructed for the study. They found that males with ADHD reported a 50 percent higher rate of frequent masturbation than males in the general population. Both males and females were less than half as likely to be satisfied with their sex life. That was almost certainly linked to the fact that ADHD participants in the sample were less likely to be in a relationship.

A second study compared 79 ADHD participants with controls. Using a validated questionnaire, the Diagnostic Interview Schedule, to assess sexual function, they found a significant positive correlation between ADHD and the items "sex drive more than the average" and "recurrent thoughts about sex' by comparison with the control group.

A third study used two validated inventories “ the Derogates Sexual Functioning Inventory and the Social Sexual Orientation Inventory“ to assess sexual function among 27 young adult males. They found their sex drive to be higher than in the control group. 

Another study, also with 27 ADHD patients, compared them with two other groups, one with fiber mitosis (benign connective tissue cancers), and the other with both ADHD and fibromatosis. They used the validated Life Satisfaction Questionnaire to assess sexual function and found that those with ADHD reported lower sex life satisfaction.

On the other hand, the only large study, with over 14,000 participants, using a non-validated questionnaire to assess sexual function, found negligible associations between ADHD and the number of sexual partners, the frequency of having sex with one's partner, and the frequency of masturbation.

Sexual dysfunctions

The Dutch study mentioned above, comparing 136 ADHD outpatients with two large surveys of the general Dutch population, used a validated self-report questionnaire, the Questionnaire for screening Sexual Dysfunctions, and a non-validated questionnaire, specially designed for the study, the Questionnaire for screening Sexual Problems. It found the rate of sexual dysfunction among both males and females with ADHD to be over twice the level in the general population. Men were four times as likely to report problems with orgasm, 50 percent more likely to report premature ejaculation, and over ten times as likely to report sexual aversion. Women were over three times as likely to report sexual excitement problems, over twice as likely to report problems with orgasm, and over three times as likely to report sexual aversion. No significant differences existed between patients treated with psychostimulants and those without such treatment.

A second study, which used a validated questionnaire to compare 79 ADHD participants with controls, found significant correlations between ADHD and aversion to sex for men but none for women.

On the other hand, a third study, comparing 32 subjects with ADHD with 293 controls, found no significant difference in the prevalence of sexual dysfunctions. It used clinical interviews to assess ADHD, and a non-validated questionnaire to assess sexual dysfunctions.

A fourth study took a very different approach. It compared 38 individuals with premature ejaculation to 27 controls. It found more than ten times the rate of ADHD symptoms among those with premature ejaculation than in the control group. Significantly, it measures premature ejaculation directly, with a stopwatch.

Conclusion

The authors concluded, "This article provides the first systematic review of sexual health among subjects with ADHD and shows that the quality of sexual health among subjects with ADHD seems poor," but acknowledged "several limitations to our review. There are only a few studies for the topics we reviewed. For many studies, the sample size was small. The methodology and measurement instruments differed, which created a potential bias."

Indeed, the study with the largest sample size found negligible associations between ADHD and sexual function, contradicting studies with small sample sizes.

Only four of the studies, all with small sample sizes, examined sexual dysfunctions. Two found strong associations with ADHD, one found none, and the fourth had mixed results.

This points to a compelling need for further research on ADHD and sexuality, with larger sample sizes.

Taiwan Nationwide Population Study Finds Link Between ADHD and Early Puberty, Also Protective Effect of Methylphenidate

Precocious puberty (PP) is defined as the onset of secondary sex characteristics before age 8 in girls or age 9 in boys.  

Because it accelerates skeletal maturation by prematurely shutting down the cartilage growth plate at the tip of long bones, it tends to lead to shorter height in adulthood. It is also known to place an additional psychological burden on children, especially girls. Girls are four to 38 times more likely to develop PP than boys. 

Taiwan has a single-payer national health insurance system, called National Health Insurance, that encompasses 99.6% of the island’s population. The Ministry of Health and Welfare uses it to maintain the National Health Insurance Research Database (NHIRD), enabling researchers to conduct nationwide population studies. 

Using this database, a Taiwanese study team investigated the relationship between ADHD and precocious puberty among children and adolescents (under 18). And because methylphenidate (MPH) is the only psychostimulant approved for the treatment of ADHD in Taiwan, the team also explored the effect of MPH on this relationship. 

Most diagnoses of ADHD in the NHIRD are made by board-certified psychiatrists, enhancing diagnostic validity. 

Of the more than 3.3 million persons born in Taiwan between 1997 and 2001, 186,681 were diagnosed with ADHD. Of these, 122,302 were prescribed MPH. 

After adjusting for sex, low-income households, and neuropsychiatric comorbidities, children diagnosed with ADHD were twice as likely to be diagnosed with PP. This held equally true for boys and girls. 

However, children diagnosed with ADHD and prescribed MPH were more than a third less likely to subsequently be diagnosed with PP than those diagnosed with ADHD but not prescribed MPH.  

For girls with ADHD, who without an MPH prescription were nine times more likely than boys with ADHD to be diagnosed with PP, an MPH prescription reduced that ratio to five times more likely than boys with ADHD and prescribed MPH. 

That suggests a strong protective effect of MPH.  

The team concluded, “Our study found that children with ADHD were at a greater risk of PP, and girls with ADHD were a particularly vulnerable group. … MPH appeared to be protective against PP in patients with ADHD, especially in girls. However, these preliminary results need further validation.” 

Taiwan Nationwide Population Study Finds No Effect of Maternal and Childhood Infection on Subsequent Offspring ADHD in Sibling Comparisons

Population Study Finds No Effect of Maternal and Childhood Infection on Subsequent Offspring ADHD

Maternal infections and inflammatory responses during pregnancy have been proposed as risk factors for neurodevelopmental disorders such as ADHD. 

Taiwan has a single-payer health insurance system that covers virtually the entirety of its population. Its Ministry of Health and Welfare maintains the National Health Insurance Research Database (NHIRD), with detailed information on outpatient services, hospitalizations, and medical treatment for nearly 99% of all residents. 

A Taiwanese study team used NHIRD to examine to examine the relationship between maternal hospitalization for infection, and early childhood infection, and subsequent ADHD in offspring. The study cohort originated with all 3,260,879 individuals born between 2001 and 2018. 

The team excluded births from foreign mothers, still births, births with congenital defects, low birth weights, abnormally late births, twins, triplets, and other multiple births, culminating in a final population cohort of 2,885,662 live-born single infants across 1,893,171 families, and 1,864,660 individuals with full siblings from 872,169 families comprising the full sibling cohort. 

Study participants were followed until diagnosis of a neurodevelopmental disorder, their death, or the end of 2021. 

After adjusting for sex, birth year, paternal and maternal ages, birthweight, birth season, parity, delivery method, 1 minute APGAR score (evaluating baby’s appearance, pulse, grimace, activity and respiration at birth), gestational age, pregnancy and delivery complications, parental history of neurodevelopmental disorders, maternal asthma and diabetes, urbanization level of the residential area, and family’s insurance amount, offspring of mothers hospitalized for infections had 14% greater odds of being subsequently diagnosed with ADHD. 

However, in the full sibling cohort of over 1.8 million, this association vanished. That held true for each of the three trimesters of pregnancy. It also held true for bacterial infections. Surprisingly, offspring of mothers hospitalized for viral infections were 24% less likely to be diagnosed with ADHD than their siblings not exposed to maternal viral infection. Because of that, they also had a 6% lower risk overall. 

After the same adjustments, early childhood infection was associated with 16% greater odds of being diagnosed with ADHD. 

Nevertheless, in the full sibling cohort of over 1.8 million, this association again vanished. That held true overall, as well as separately for childhood infections in months 1-6 and months 7-12. The association vanished altogether both for bacterial infections as well as for viral infections. 

The authors concluded, “the results of this nationwide birth cohort study with population and sibling analyses suggest that the association between maternal infection during pregnancy and offspring neurodevelopmental risk is largely due to familial confounding factors.”

Australian Nationwide Survey Finds More Than Tenfold Greater Odds of Suicidality or Self-harm Among Children with ADHD

Most previous studies of suicide and self-harm risk among persons with ADHD have focused on adolescents and adults. They’ve also tended to be cross-sectional, analyzing data from a population at a specific point in time. 

An Australian study team took a different approach, conducting a before-and-after study through the birth cohort of the Longitudinal Study of Australian Children (LSAC), comprising 5,107 children who have been followed up every two years since birth. 

The diagnosis of ADHD was based on parents reporting that their child had received a diagnosis of ADHD at or before age ten.  

Suicide and self-harm were defined as children’s self-report at age 14 of any thought or attempt of suicide and self-harm respectively over the past year. 

The team adjusted for the following confounders: socioeconomic status, birth weight, ADHD medication history, maternal education level, maternal age at birth, experience in bullying victimization at age 12, and depression score based on Short Mood and Feelings Questionnaire (SMFQ). 

Of the 5,107 participants, 3,696 had all the valid data required for analysis and were included in the final cohort. Of these, 3.6% were diagnosed with ADHD by age 10. 

With diagnosis of ADHD at age 10 and all other factors held constant: 

  • The odds of suicidal thought, plan, or attempt at age 14 increased elevenfold. This was twice as pronounced among boys as among girls. 
  • The odds of self-harm at age 14 increased 25-fold. This was more than three times as pronounced among boys as among girls. 

Both depression and exposure to bullying were statistically significant mediators for the relationship. Nevertheless, depression and exposure to bullying each accounted for well under 10% of the overall effect. 

Neither socioeconomic status nor maternal factors had any significant mediating effect on outcomes. 

Conclusion:

The authors concluded, “This study provides compelling evidence that children diagnosed with ADHD at the age of 10 years face significantly elevated risks of experiencing suicidal thoughts, planning, or attempts, as well as self-harm, by the age of 14 years, which underscores the critical importance of recognizing and addressing these heightened risks in children with ADHD.” 

While factors like depression and bullying contribute, ADHD itself remains a key risk factor. Early intervention and strong mental health support are crucial to protecting these children’s well-being.
