Unusual sexual disorders every doctor should know about

M3 Global Newsdesk Feb 15, 2020

Talking to patients about erectile dysfunction (ED) used to be taboo. Now, even men without ED try Viagra. But asking about the “little blue pill” is the exception when talking—or, more likely, not talking—about sexual dysfunctions and disorders. Why? Because patients don’t like to bring them up and doctors sometimes don’t ask about them. This means those less-common sexual problems go undiagnosed, and therefore untreated. 


In an attempt to shed light on these, let’s take a look at five uncommon sexual disorders that deserve greater attention.


Sexsomnia

This condition is a specialised non-REM parasomnia, in which affected patients vocalise, masturbate, fondle, or attempt intercourse while sleeping. When these people wake up, they don’t remember anything.

According to limited research, this condition preferentially affects men (67-81% male predominance) and begins between 26 and 33 years on average. Unsurprisingly, this condition may lead to interpersonal, clinical, and criminal repercussions. Sexsomnia likely exists on a continuum starting with sleepwalking.

Interestingly, obstructive sleep apnoea is a recognised precipitant of sex-arousal disorders. In a handful of those treated for sleep apnoea, these disorders abated. Other possible treatments include maintaining sleep hygiene, antidepressants, and refraining from drugs and alcohol.


Postorgasmic illness syndrome

Postorgasmic illness syndrome (POIS) is an illness that causes a patient to experience flu-like and allergy symptoms post-orgasm. It mostly affects men but women can also experience POIS, too. Symptoms develop soon after orgasm.  These include fatigue, weakness, fever, mood changes, memory problems, concentration problems, sore throat, and itchy eyes, and commonly last between 2 and 7 days.

The aetiology of POIS remains unknown, but some experts think that in men it could be an autoimmune or allergic reaction to semen. Other experts hypothesise that it could be due to a chemical imbalance in the brain. 

POIS can be extremely distressing for patients and their partners. Although no definitive treatment for this condition exists, some men have tried SSRI antidepressants, benzodiazepines, or antihistamines. When all else fails, abstinence is an option. Alternatively, sex can be scheduled for when a person has enough time to cope and recover. 


Persistent genital arousal disorder

Talk about uncomfortabe. Persistent genital arousal disorder (PGAD), a syndrome marked by spontaneous sexual arousal or orgasm primarily affects women. These orgasms are unpleasant, and some women found relief via masturbation. Most of these patients are sent for psychiatric treatment, although there appears to be a neurological underpinning.

“We hypothesise that many cases of PGAD are caused by unprovoked firing of C-fibers in the regional special sensory neurons that subserve sexual arousal,” the authors wrote. “Some PGAD symptoms may share pathophysiologic mechanisms with neuropathic pain and itch.”

Bolstering the position that PGAD is more neurological in nature is the observation that psychiatric treatment is ineffective, and that neurological tests in several patients found spinal nerve root lesions, nerve conduction abnormalities, and sensory nerve disorders. Neurological treatment following neurological evaluation has helped some. Interventions that have shown efficacy in individual patients include surgery to remove sacral nerve cysts and administration of IV immune globulin, as well as tapering doses of antidepressants.


Retrograde ejaculation

When a man has an orgasm, a sphincter muscle shuts off access to the bladder so that semen can propel through the urethra. With retrograde ejaculation, a disorder of this muscle causes semen to divert into the bladder. Common causes include complications from prostate surgery, adverse effects of drugs such as SSRIs or medications used to treat enlarged prostate, and nerve damage caused by multiple sclerosis or uncontrolled diabetes.

For most men, the symptoms of retrograde ejaculation are benign. Treatment can consist of medication discontinuance if drugs are the cause. If due to nerve or muscle damage of the bladder, pseudoephedrine or imipramine could ameliorate muscle tone at the bladder entrance. Finally, in vitro fertilization may be an option for those interested in having children.


Sexual desire disorders

The sexual response cycle is impacted by biopsychosocial factors and comprises four phases including desire, arousal, orgasm, and resolution. Desire, in turn, consists of three parts: sexual drive, sexual motivation, and sexual wish. Sexual drive results from psychoneuroendocrine mechanisms.

Hypoactive sexual desire disorder (HSDD) and sexual aversion disorder (SAD) are two types of sexual desire disorders. These conditions likely exist on a spectrum, with SAD being more severe.

HSDD is defined as a persistent deficiency or lack of sexual fantasy or desire for sex. SAD involves aversion and avoidance of sexual contact with a partner. Subtypes include generalised, acquired, lifelong, situational, secondary to psychological factors, and secondary to combined factors.

Treatment for sexual desire disorders includes analytically-oriented sex therapy and psychotherapy, such as cognitive behavioral therapy. Of note, SAD is often progressive and refractory to treatment. Additionally, various hormone replacement treatments, as well as bupropion, herbal remedies, and even amphetamine and methylphenidate have been tried, with mixed success.


Addressing patients’ sexual problems

“Sexual desire disorders are underrecognised, under-treated disorders leading to a great deal of morbidity in relationships,” wrote Keith A. Montgomery, MD, in the journal Psychiatry. “By becoming more familiar with prevalence, etiology, and treatment of sexual desire disorders, physicians hopefully will become more comfortable with the topic so that they can adequately address patients’ sexual problems and to implement appropriate treatment.”
