SexualDysfunctionandGenderDysphoria

Sexual dysfunctions are an inability to respond to sexual stimulation, or the
experience of pain during the sexual act. It is defined by disturbance in the
subjective sense of pleasure or desire associated with sex, or by the objective
performance.IntheDiagnosticandStatisticalManualofMentalDisorders,fifth
edition(DSM-5),thesexualdysfunctionsincludemalehypoactivesexualdesire
disorder, female sexual interest/arousal disorder, erectile disorder, female
orgasmic disorder, delayed ejaculation, premature (early) ejaculation, genitopelvic pain/penetration disorder, substance/medication-induced sexual
dysfunction, other specified sexual dysfunction, and unspecified sexual
dysfunction.Ifmorethanonedysfunctionexists,theyshouldallbediagnosed.
Sexual dysfunctions can be lifelong or acquired, generalized or situational,
and result from psychological factors, physiologic factors, or combined
factors. As per DSM-5 dysfunction due to a general medical condition,
substance use, or adverse effects of medication should be noted. Sexual
dysfunctionmaybediagnosedinconjunctionwithanotherpsychiatricdisorder
(depressive disorders, anxiety disorders, personality disorders, and
schizophrenia).
I. Desire,Interest,andArousalDisorders
A. Male hypoactive sexual desire disorder. Characterized by a lack or
absence of sexual fantasies and desire for minimum duration of 6
months.Menmayhaveneverexperiencederotic/sexualthoughtsandthe
dysfunction can be lifelong. The prevalence is greatest in the younger
(6%ofmenages18to24)andolder(40%ofmenages66to74)with
only2%aged16to44affectedbythisdisorder.
Patientswithdesireproblemsoftenuseinhibitionofdesiredefensively,
to protect against unconscious fears about sex. Lack of desire can also
result from chronic stress, anxiety, or depression or the use of various
psychotropic drugs and other drugs that depress the central nervous
system(CNS).Insextherapyclinicpopulations,lackofdesireisoneof


themostcommoncomplaintsamongmarriedcouples,withwomenmore


affectedthanmen.
Thediagnosisshouldnotbemadeunlessthelackofdesireisasource
ofdistresstoapatient.SeeTable18-1.
B. Female sexual interest/arousal disorder. The combination of interest
(or desire) and arousal reflects that women do not necessarily move
stepwise from desire to arousal, but experience desire synchronously
with,orevenfollowingfeelingsofarousal.Consequently,womenmay
experience either/or both inability to feel interest or arousal, difficulty
achievingorgasmorexperiencepain.Usualcomplaintsincludedecrease

Subjective sense of arousal is poorly correlated with genital
lubrication in both normal and dysfunctional women. A woman
complaining of lack of arousal may lubricate vaginally, but may not
experienceasubjectivesenseofexcitement.Theprevalenceisgenerally
underestimated. In one study of subjectively happily married couples,
33% of women described arousal problems. Difficulty in maintaining
excitement can reflect psychological conflicts (e.g., anxiety, guilt, and
fear) or physiologic changes. Alterations in testosterone, estrogen,
prolactin, and thyroxin levels have been implicated in female sexual

arousal disorder. In addition, medications with antihistaminic or
anticholinergic properties cause a decrease in vaginal lubrication.
Relationship problems are particularly relevant to acquired
interest/arousal disorder. In one study of couples with markedly
decreased sexual interaction, the most prevalent etiology was marital
discord.SeeTable18-2.
C. Maleerectiledisorder.Inlifelongmaleerectiledisorderonehasnever
been able to obtain an erection while in acquired type one has
successfullyachievedpenetrationatsometimeinhissexuallife.
Erectiledisorderisreportedin10%to20%ofallmenandisthechief
complaint of more than 50% of all men treated for sexual disorders.


Lifelong male erectile disorder is rare; it occurs in about 1% of men
younger than age 35. The incidence increases with age and has been
reported around 2% to 8% of the young adult population. The rate
increasesto40%to50%inmenbetweenagesof60and70.
Male erectile disorder can be organic or psychological, or a
combination but in young and middle-aged men the cause is usually
psychological.Ahistoryofspontaneouserections,morningerections,or
good erections with masturbation or with partners other than the usual
one indicates functional impotence. Psychological causes of erectile
dysfunction include a punitive conscience or superego, an inability to
trust, or feelings of inadequacy. Erectile dysfunction also may reflect
relationshipdifficultiesbetweenpartners.SeeTable18-3.

II. OrgasmDisorders
A. Female orgasmic disorder. Female orgasmic disorder (anorgasmia or
inhibitedfemaleorgasm)isarecurrentorpersistentdelayinorabsence
of orgasm following a normal sexual excitement phase. In lifelong
femaleorgasmicdisorder,onehasneverexperiencedanorgasmbyany
kind of stimulation while in acquired orgasmic disorder one has
previously experienced at least one orgasm. The disorder is more
commonamongunmarriedwomen.Theestimatedproportionofmarried
women over age 35 who never have achieved orgasm is 5%. The
proportion is higher in unmarried women and younger women. The
overall prevalence of inhibited female orgasm is 30%. Psychological

B. Delayedejaculation.Inmaledelayedejaculation(retardedejaculation),
a man achieves ejaculation during coitus with great difficulty, if at all.
The problem occurs mostly during coital activity. Lifelong inhibited

male orgasm usually indicates more severe psychopathology. Acquired
ejaculatory inhibition frequently reflects interpersonal difficulties. The

Difficulty in ejaculatory control may be associated with anxiety
regarding the sex act and with unconscious fears about the vagina. It
may also be the result of conditioning if the man’s early sexual

III. SexualPainDisorders
A. Genito-pelvic pain/penetration disorder. In DSM-5, this disorder
referstooneormoreofthefollowingcomplaints,ofwhichanytwoor
more may occur together: difficulty having intercourse; genito-pelvic
pain;fearofpainorpenetration;andtensionofthepelvicfloormuscles.
Previously, these were diagnosed as dyspareunia or vaginismus and
could coexist and lead to fear of pain with sex. These diagnoses are
categorizedintoonediagnosticcategorybutforthepurposesofclinical
discussionthedistinctcategoriesofdyspareuniaandvaginismusremain
clinicallyuseful.SeeTable18-7.
1. Dyspareunia. Dyspareunia is recurrent or persistent genital pain
occurringbefore,during,orafterintercourse.Dyspareuniaisrelated
to vaginismus and repeated episodes of vaginismus can lead to
dyspareunia. DSM-5 cites that 15% of women in North America
reportrecurrentpainduringintercourse.

Chronic pelvic pain is a common complaint in women with a
history of rape or childhood sexual abuse. Painful coitus can result
from tension and anxiety and makes intercourse unpleasant or
unbearable. Dyspareunia is uncommon in men and is usually
associated with a medical condition (e.g., Peyronie’s disease).
Dyspareuniamaypresentasanyofthefourcomplaintslistedunder
genito-pelvic pain/penetration disorder and should be diagnosed as
genito-pelvicpain/penetrationdisorder.

notimpossible.
It mostly afflicts highly educated women and of high
socioeconomicgroups.Asexualtrauma,suchasrape,orunpleasant
first coital experience may cause vaginismus. A strict religious
upbringing in which sex is associated with sin is frequent in these

patients.
IV. SexualDysfunctionDuetoaGeneralMedicalCondition

ofallsurgicalproceduresonthefemalegenitalarearesultintemporary
dyspareunia.Inaddition,30%to40%ofwomenwiththecomplaintwho
are seen in sex therapy clinics have pelvic pathology. Organic
abnormalitiesleadingtodyspareuniaandvaginismusincludeirritatedor
infected hymenal remnants, episiotomy scars, Bartholin’s gland
infection, various forms of vaginitis and cervicitis, endometriosis, and
adenomyosis. Postcoital pain has been reported by women with
myomata, endometriosis, and adenomyosis, and is attributed to the
uterine contractions during orgasm. Postmenopausal women may have
dyspareuniaresultingfromthinningofthevaginalmucosaandreduced
lubrication.
Two conditions not readily apparent on physical examination that
producedyspareuniaarevulvarvestibulitisandinterstitialcystitis.

C. Male hypoactive sexual desire disorder and female interest/arousal


disorderduetoageneralmedicalcondition.Sexualdesirecommonly
decreases after major illness or surgery, particularly when the body
image is affected after such procedures as mastectomy, ileostomy,
hysterectomy,andprostatectomy.Insomecases,biochemicalcorrelates
are associated with hypoactive sexual desire disorder (Table 18-9).
Drugs that depress the CNS or decrease testosterone production can
decreasedesire.
D. Other male sexual dysfunction due to a general medical condition.
Delayed ejaculation can have physiologic causes and can occur after
surgeryonthegenitourinarytract,suchasprostatectomy.Itmayalsobe
associated with Parkinson’s disease and other neurologic disorders
involving the lumbar or sacral sections of the spinal cord. The
antihypertensive drug guanethidine monosulfate (Ismelin), methyldopa
(Aldomet),thephenothiazines,thetricyclicdrugs,andtheSSRIs,among
others,havebeenimplicatedinretardedejaculation(Table18-10).
E. Otherfemalesexualdysfunctionduetoageneralmedicalcondition.
Some medical conditions—specifically, endocrine diseases such as
hypothyroidism, diabetes mellitus, and primary hyperprolactinemia—
canaffectawoman’sabilitytohaveorgasms.
F. Substance/medication-induced sexual dysfunction. The diagnosis of
substance-induced sexual dysfunction is used when evidence of

substance intoxication or withdrawal is apparent from the history,
physicalexamination,orlaboratoryfindings.Thedisturbanceinsexual
functionmustbepredominantintheclinicalpicture.SeeTable18-11.In
general, sexual function is negatively affected by serotonergic agents,
dopamineantagonists,drugsthatincreaseprolactin,anddrugsthataffect
the autonomic nervous system. With commonly abused substances,
dysfunctionoccurswithinamonthofsignificantsubstanceintoxication
orwithdrawal.Insmalldoses,somesubstances(e.g.,amphetamine)may
enhance sexual performance, but abuse impairs erectile, orgasmic, and
ejaculatorycapacities.
Oral contraceptives are reported to decrease libido in some women,
andsomedrugswithanticholinergicsideeffectsmayimpairarousalas
wellasorgasm.Benzodiazepineshavebeenreportedtodecreaselibido,
but in some patients the diminution of anxiety caused by those drugs
enhances sexual function. Both increase and decrease in libido have
been reported with psychoactive agents. Alcohol may foster the
initiation of sexual activity by removing inhibition, but it also impairs
performance. Sexual dysfunction associated with the use of a drug


disappears when the drug is discontinued. Table 18-12 lists psychiatric
medicationsthatmayinhibitfemaleorgasm.

every pharmacologic agent, particularly those used in psychiatry, has
beenassociatedwithaneffectonsexuality.Theeffectsofpsychoactive
drugsaredetailedlaterinthissection.Foradetailedlistofmedication
thatimpactsexualfunctioning,seeTable18-13.
1. Antipsychotic drugs. Most antipsychotic drugs are dopamine
receptor antagonists that also block adrenergic and cholinergic
receptors,thusaccountingfortheadversesexualeffects.
2. Antidepressantdrugs. The tricyclic and tetracyclic antidepressants
have anticholinergic effects that interfere with erection and delay
ejaculation.Clomipramine(Anafranil)hasbeenreportedtoincrease
sex drive in some persons. Selegiline (Deprenyl), a selective MAO


type B (MAOB) inhibitor, and bupropion (Wellbutrin) also increase
sex drive. SSRIs and SNRIs lower the sex drive and difficulty
reachingorgasmoccurinbothsexes.

dBenzodiazepineshavebeenreportedtodecreaselibido,butinsomepatientsthediminutionof
anxietycausedbythosedrugsenhancessexualfunction.
eAllSSRIscanproducesexualdysfunction,morecommonly,inmen.

a. Lithium. Lithium (Eskalith) regulates mood and, in the manic
state, may reduce hypersexuality, possibly by a dopamine
antagonist activity. In some patients, impaired erection has been
reported.
b. Sympathomimetics. Psychostimulants raise the plasma levels of
norepinephrine and dopamine. Libido is increased; however, with
prolongeduse,menmayexperiencealossofdesireanderections.
c. a-Adrenergic and β-adrenergic receptor antagonists. αAdrenergic and β-adrenergic receptor antagonists diminish tonic
sympatheticnerveoutflowfromvasomotorcentersinthebrainand
that can cause impotence, decrease the volume of ejaculate, and
produceretrogradeejaculation.
3. Anticholinergics. The anticholinergics block cholinergic receptors
andcausedrynessofthemucousmembranes(includingthoseofthe
vagina) and erectile disorder. However, amantadine may reverse
SSRI-inducedorgasmicdysfunctionthroughitsdopaminergiceffect.
4. Antihistamines. Drugs such as diphenhydramine (Benadryl) may
inhibitsexualfunction.Cyproheptadine,althoughanantihistamine,is

a serotonin antagonist and reverses sexual adverse effects produced
bySSRIs.
5. Antianxiety agents. Benzodiazepines diminish anxiety, and as a
resulttheyimprovesexualfunctioninpersonsinhibitedbyanxiety.
6. Alcohol. Alcohol can produce erectile disorders in men but
paradoxically increase testosterone levels in women. This may
account for women to have increased libido after drinking small
amountsofalcohol.
7. Opioids. Opioids, such as heroin, have adverse sexual effects, such
as erectile failure and decreased libido. The alteration of
consciousness may enhance the sexual experience in occasional
users.
V. Treatment
Treatmentfocusesontheexplorationofunconsciousconflicts,motivation,


fantasy, and various interpersonal difficulties. Methods that have proved
effectivesinglyorincombinationinclude(1)traininginbehavioral–sexual
skills, (2) systematic desensitization, (3) directive marital therapy, (4)
psychodynamic approaches, (5) group therapy, (6) pharmacotherapy, (7)
surgery, and (8) hypnotherapy. Evaluation and treatment must address the
possibilityofaccompanyingpersonalitydisordersandphysicalconditions.

B. Specifictechniquesandexercises
Varioustechniquesareusedtotreatthevarioussexualdisorders.
1. Vaginismus. The woman is advised to dilate her vaginal opening
withherfingersorwithdilators.
2. Prematureejaculation. The squeeze technique is used to raise the
threshold of penile excitability. The patient or his partner forcibly
squeezes the coronal ridge of the glans at the first sensation of
impending ejaculation. The erection is diminished and ejaculation
inhibited. A variation is the stop–start technique. Stimulation is
stoppedasexcitementincreases,butnosqueezeisused.
3. Maleerectiledisorder.Themanissometimestoldtomasturbateto
demonstratethatfullerectionandejaculationarepossible.
4. Female orgasmic disorder (primary anorgasmia). The woman is
instructed to masturbate, sometimes with the use of a vibrator. The
useoffantasyisencouraged.
5. Retarded ejaculation. It is managed by extravaginal ejaculation
initially and gradual vaginal entry after stimulation to the point of
nearejaculation.
C. Hypnotherapy. Hypnotherapists focus specifically on the anxietyproducing situation—that is, the sexual interaction that results in
dysfunction. The successful use of hypnosis enables patients to gain
control over the symptom that has been lowering self-esteem and
disrupting psychological homeostasis. The focus of treatment is on


symptom removal and attitude alteration. Hypnosis may be added to a
basic individual psychotherapy program to accelerate the effects of
psychotherapeuticintervention.

modalities is the integration of sex therapy (training in behavioral–
sexual skills) with psychodynamic and psychoanalytically oriented
psychotherapy. Psychodynamic conceptualizations are added to

H. Biologic treatments. Biologic treatments, including pharmacotherapy,
surgery, and mechanical devices, are used to treat specific cases of
sexual disorder. Most of the recent advances involve male sexual
dysfunction.Currentstudiesareunderwaytotestbiologictreatmentof

I. Pharmacotherapy.Mostpharmacologictreatmentsinvolvemalesexual

physiologic, psychological, or mixed causes. In the latter two cases,
pharmacologic treatment is usually used in addition to a form of
psychotherapy.
J. Treatmentoferectiledisorderandprematureejaculation.Themajor
new medications to treat sexual dysfunction are sildenafil (Viagra) and
its congeners (Table 18-14); oral phentolamine (Vasomax); alprostadil

(Caverject), and injectable medications; papaverine, prostaglandin E1,
phentolamine,orsomecombinationofthese(Edex);andatransurethral

VI. OtherSpecifiedSexualDysfunctions
Many sexual disorders are not classifiable as sexual dysfunctions or as
paraphilias. These unclassified disorders are rare, poorly documented, not
easily classified, or not specifically described in DSM-5. Never-the-less
theyaresyndromesthattherapistshaveseenclinically.SeeTable18-15.
A. Postcoital dysphoria. Occurs during the resolution phase of sexual
activity,whenpersonsnormallyexperienceasenseofgeneralwell-being
and muscular and psychological relaxation. Some persons become
depressed,tense,anxious,andirritable,andshowpsychomotoragitation.
They often want to get away from their partners and may become

D. Sex addiction and compulsivity. The concept of sex addiction
developed over the last two decades to refer to persons who
compulsivelyseekoutsexualexperiencesandwhosebehaviorbecomes
impairediftheyareunabletogratifytheirsexualimpulses.
In DSM-5, the terms sex addiction or compulsive sexuality are not
used,norisitadisorderthatisuniversallyrecognizedoraccepted.Such
persons show repeated and increasingly frequent attempts to have a
sexual experience, deprivation of which gives rise to symptoms of
distress.
ThesignsofsexualaddictionarelistedinTable18-16.
E. Typesofbehavioralpatterns.Theparaphiliasconstitutethebehavioral
patterns most often found in the sex addict. The essential features of a
paraphilia are recurrent, intense sexual urges or behaviors, including
exhibitionism, fetishism, frotteurism, sadomasochism, cross-dressing,
voyeurism, and pedophilia. Paraphilias are associated with clinically
significant distress and almost invariably interfere with interpersonal
relationships,andtheyoftenleadtolegalcomplications.

Another and more prevalent style of intervention is directed at
enabling persons with persistent and marked distress about sexual
orientation to live comfortably with homosexuality without shame,
guilt,anxiety,ordepression.Gaycounselingcentersareengagedwith
patients in such treatment programs. The American Psychiatric

Overall,conversiontherapyhasbeendiscredited.
Persistent genital arousal disorder. Persistent genital arousal
disorder(PGAD)haspreviouslybeencalledpersistentsexualarousal
syndrome. It has been diagnosed in women who complain of a
continualfeelingofsexualarousal,whichisuncomfortable,demands
release,andinterfereswithlifepleasuresandactivities.Thesewomen
masturbate frequently, sometimes incessantly, because climax
provides relief. However, the relief is temporary and the sense of
arousal returns rapidly and remains. The sense of arousal in these

cases is neither pleasurable nor exciting. One case of attempted
suicide has been reported with this syndrome. There is some
speculationthatthisdisorderisduetonervedamageoranomaly,but
theetiologyisunknown.
Femaleprematureorgasm.Acaseofmultiplespontaneousorgasms
without sexual stimulation was seen in a woman; the cause was an
epileptogenic focus in the temporal lobe. Instances have been
reported of women taking antidepressants (e.g., fluoxetine and
clomipramine) who experience spontaneous orgasm associated with
yawning.
Postcoitalheadache.Postcoitalheadache,characterizedbyheadache
immediately after coitus, may last for several hours. It is usually
describedasthrobbingandislocalizedintheoccipitalorfrontalarea.
Thecauseisunknown.
Orgasmicanhedonia.Orgasmicanhedoniaisaconditioninwhicha
person has no physical sensation of orgasm, even though the
physiologiccomponent(e.g.,ejaculation)remainsintact.
Masturbatory pain. Persons may experience pain during


masturbation. Organic causes should always be ruled out; a small
vaginal tear or early Peyronie’s disease can produce a painful
sensation. The condition should be differentiated from compulsive
masturbation.
VII. GenderDysphoria
A. Introduction.Thetermgenderdysphoriareferstothosepersonswitha
marked incongruence between their experienced or expressed gender
andtheonetheywereassignedatbirth.
Thetermgenderidentityreferstothesenseonehasofbeingmaleor
female, which corresponds most often to the person’s anatomical sex.

Persons with gender dysphoria express their discontent with their
assigned sex as a desire to have the body of the other sex or to be
regardedsociallyasapersonoftheothersex.
The term transgender is a general term used to refer to those who
identify with a gender different from the one they were born with
(sometimesreferredtoastheirassignedgender).
B. Genderidentitydisorders.Agroupofdisordersthathaveastheirmain
symptomapersistentpreferencefortheroleoftheoppositesexandthe
feelingthatonewasbornintothewrongsex.
People with disordered gender identity try to live as or pass as
members of the opposite sex. Transsexuals want biologic treatment
(surgery, hormones) to change their biologic sex and acquire the
anatomiccharacteristicsoftheoppositesex.Thedisordersmaycoexist
withotherpathologyorbecircumscribed,withpatientsfunctioningably
inmanyareasoftheirlives.
C. Diagnosis,signs,andsymptoms
1. Children. Gender dysphoria in children is incongruence between
expressed and assigned gender, with the most important criterion

D. Epidemiology
1. Unknown,butrare.
2. Male-to-femaleratiois4:1.
3. Almostallgender-disorderedfemaleshaveahomosexualorientation.
4. Fifty percent of gender-disordered males have a homosexual
orientation, and 50% have a heterosexual, bisexual, or asexual
orientation.
5. The prevalence rate for transsexualism is 1 per 10,000 males and 1
per30,000females.
E. Etiology
Biologic. Testosterone affects brain neurons that contribute to
masculinizationofthebraininsuchareasasthehypothalamus.Whether
testosterone contributes to so-called masculine or feminine behavioral
patternsingenderidentitydisordersremainscontroversial.Sexsteroids

(i.e., testosterone can increase libido and aggressiveness in men and
women, while estrogen or progesterone can decrease libido and
aggressivenessinmen).

exhibitionism, sexual sadism, sexual masochism, fetishism, and
transvestism with explicit diagnostic criteria because of their threat to
others and/or because they are relatively common paraphilias. They are
more common in men than in women. Cause is unknown. A biologic
