Orgasms and Epilepsy

By Amee Baird Ph.D. Posted Jan 11, 2020

Of all neurological diseases, epilepsy is the one that has been most frequently linked to sex. “Coitus brevis epilepsia est” (“Sex is a brief seizure”) is an ancient proverb attributed to Galen, the famous physician of the Roman Empire. In the 18th and 19th centuries, some doctors, including Samuel-Auguste Tissot and Edward Sieveking, argued that excessive masturbation could cause epilepsy. At the time, castration and clitoridectomy (removal of the clitoris) were reportedly performed on people with severe epilepsy.

Renowned neurologists John Hughlings Jackson and William Gowers did not consider sex to be the origin of epilepsy. Rather, they identified neurophysiological (brain-based) causes and laid the foundations for current views of the origins of epilepsy.

The notion that sex causes epilepsy has been well and truly debunked, but in rare cases, an association between sex and seizures does exist. Temporal lobe seizures can be triggered by an orgasm, or even cause orgasms. Orgasm-induced seizures occur much more commonly in women than in men and are usually associated with a right temporal lobe seizure focus.

These seizures can be frightening for partners and have a significant impact on a person’s sex life. They can lead to a life spent avoiding sex and fear of orgasm, which can have a devastating effect on relationships. In one case, the husband of a woman who experienced orgasm-induced seizures was so frustrated by their sex life that he threatened divorce if neurosurgery to cure her seizures was not successful. 

In contrast to orgasm-induced seizures, seizures that result in orgasms may be savoured by those who experience them. Orgasmic “auras” (a feeling or warning sign that a seizure is about to happen) linked to seizures are also more common in women and typically arise from the right temporal lobe.

Case studies of women who experience these pleasurable seizures have found that they often keep them a secret from their doctors – for decades in some cases – even when they are undergoing investigations for epilepsy and know that orgasmic auras are part of their seizures. Some people have refused to have neurosurgery to cure their seizures out of fear of losing these unexpected orgasms.

Spontaneous orgasms might sound like fun, but these sexual seizures can occur suddenly and in unexpected situations. Imagine travelling on a bus during peak hour on your way to work, standing in the aisle jammed in between other passengers, and suddenly feeling a wave of tingling. You know what is coming, and you know that you are about to experience it in front of an audience of strangers.

Brain imaging studies of healthy men and women have found that orgasm, and its lead-up, is predominantly associated with activation (and, in some earlier studies, deactivation) in the temporal and frontal brain regions, including the amygdala and orbitofrontal cortex; other regions involved in sensory, motor and reward processes are also implicated. It appears that if the neurons (the nerve cells) in those very brain regions are highly sensitive, perhaps due to scar tissue or other causes of seizures, such as hippocampal sclerosis, then a seizure can be triggered by the activation or stimulation of those exact regions that occurs during orgasm.

Apart from orgasm, there are other sexual behaviours that can occur during a seizure. Sexual automatisms (automatic behaviours that the person later has no memory of) include writhing, thrusting, rhythmic movement of the pelvis and legs, and rhythmic handling of genitals or masturbation. These are rare and occur relatively equally in men and women who experience frontal lobe seizures.

Sexual “ictal” manifestations (that is, those that occur during a seizure) have also been reported, such as erotic feelings, genital sensations and sexual desire; these have been found to occur most commonly in women with right temporal lobe seizures.

So although sex does not cause epilepsy, sexual behaviours can be associated with certain types of seizures that arise from the temporal (typically right-sided) or frontal lobes, brain regions that are critical parts of our sexual neural network.

[WEB SITE] Sexuality After Traumatic Brain Injury – MSKTC

How does a traumatic brain injury affect sexual functioning?

The following changes in sexual functioning can happen after TBI:

  • Decreased Desire: Many people may have less desire or interest in sex.
  • Increased Desire: Some people have increased interest in sex after TBI and may want to have sex more often than usual. Others may have difficulty controlling their sexual behavior. They may make sexual advances in inappropriate situations or make inappropriate sexual comments.
  • Decreased Arousal: Many people have difficulty becoming sexually aroused. This means that they may be interested in sex, but their bodies do not respond. Men may have difficulty getting or keeping an erection. Women may have decreased vaginal lubrication (moisture in the vagina).
  • Difficulty or Inability to Reach Orgasm/Climax: Both men and women may have difficulty reaching orgasm or climax. They may not feel physically satisfied after sexual activity.
  • Reproductive Changes: Women may experience irregular menstrual cycles or periods. Sometimes, periods may not occur for weeks or months after injury. They may also have trouble getting pregnant. Men may have decreased sperm production and may have difficulty getting a woman pregnant.

What causes changes in sexual functioning after TBI?

There are many reasons sexual problems happen after TBI. Some are directly related to damage to the brain. Others are related to physical problems or changes in thinking or relationships.

  • Possible causes of changes in sexual functioning after TBI include:
  • Damage to the Brain: Changes in sexual functioning may be caused by damage to the parts of the brain that control sexual functioning.
  • Hormonal Changes: Damage to the brain can affect the production of hormones, like testosterone, progesterone, and estrogen. These changes in hormones affect sexual functioning.
  • Medication Side Effects: Many medications commonly used after TBI have negative side effects on sexual functioning.
  • Fatigue/Tiredness: Many people with TBI tire very easily. Feeling tired, physically or mentally, can affect your interest in sex and your sexual activity.
  • Problems with Movement: Spasticity (tightness of muscles), physical pain, weakness, slowed or uncoordinated movements, and balance problems may make it difficult to have sex.
  • Self-Esteem Problems: Some people feel less confident about their attractiveness after TBI. This can affect their comfort with sexual activity.
  • Changes in Thinking Abilities: Difficulty with attention, memory, communication, planning ahead, reasoning, and imagining can also affect sexual functioning.
  • Emotional Changes: Individuals with TBI often feel sad, nervous, or irritable. These feelings may have a negative effect on their sexual functioning, especially their desire for sex.
  • Changes in Relationships and Social Activities: Some people lose relationships after TBI or may have trouble meeting new people. This makes it difficult to find a sexual partner.
