What percentage of men have self-reported Premature Ejaculation (PE)?
A) Less than 5%
B) 30%
C) 50%
D) 70%
B) 30%
Explanation: While up to 30% of men have self-reported PE, few of these men have an ejaculation latency time of less than two minutes, making the actual prevalence of clinical PE and DE less than 5%.
What is the primary role of the clinician in managing disorders of ejaculation?
A) To conduct appropriate investigation
B) To provide education
C) To offer available treatments based on sound scientific data
D) All of the above
D) All of the above
Explanation: The role of the clinician in managing PE and DE is to conduct appropriate investigation, to provide education, and to offer available treatments that are rational and based on sound scientific data.
What are Premature Ejaculation (PE) and Delayed Ejaculation (DE)?
Ejaculation and orgasm are distinct but simultaneous events that occur with peak sexual arousal. It is typical for men to have some control over the timing of ejaculation during a sexual encounter. Men who ejaculate before or shortly after penetration, without a sense of control, and who experience distress related to this condition may be diagnosed with Premature Ejaculation (PE). On the other hand, there also exists a population of men who experience difficulty achieving sexual climax, sometimes to the point that they are unable to climax during sexual activity; these men may be diagnosed with Delayed Ejaculation (DE).
What is the prevalence of clinical PE and DE?
While up to 30% of men have self-reported PE, few of these men have an ejaculation latency time of less than two minutes, making the actual prevalence of clinical PE and DE less than 5%.
What are the primary treatment options for PE and DE?
A number of psychological health, behavioral, and pharmacotherapy options exist for both PE and DE. However, none of these pharmacotherapy options have achieved approval from the United States Food and Drug Administration and their use in the treatment of PE is considered off-label. The role of the clinician in managing PE and DE is to conduct appropriate investigation, to provide education, and to offer available treatments that are rational and based on sound scientific data. It is also recommended to involve sexual partner(s) in decision making, when possible, to allow for optimization of outcomes.
What is the role of the clinician in managing disorders of ejaculation?
The role of the clinician in managing PE and DE is to conduct appropriate investigation, to provide education, and to offer available treatments that are rational and based on sound scientific data. The Panel recommends shared decision-making as fundamental in the management of disorders of ejaculation; involvement of sexual partner(s) in decision making, when possible, may allow for optimization of outcomes.
What is the definition of lifelong premature ejaculation?
a. Consistently poor ejaculatory control, associated bother, and ejaculation latency that is markedly reduced from prior sexual experience during penetrative sex.
b. Poor ejaculatory control, associated bother, and ejaculation within about 2 minutes of initiation of penetrative sex that has been present since sexual debut.
c. Lifelong, consistent, bothersome inability to achieve ejaculation or excessive latency of ejaculation despite adequate sexual stimulation and the desire to ejaculate.
d. None of the above.
b. Poor ejaculatory control, associated bother, and ejaculation within about 2 minutes of initiation of penetrative sex that has been present since sexual debut.
Explanation: Lifelong premature ejaculation is defined as poor ejaculatory control, associated bother, and ejaculation within about 2 minutes of initiation of penetrative sex that has been present since sexual debut. This is according to expert opinion.
What is the first-line pharmacotherapy recommended in the treatment of premature ejaculation?
a. Daily SSRIs; on demand clomipramine or dapoxetine (where available); and topical penile anaesthetics
b. α1-adrenoreceptor antagonists
c. Tramadol
d. Oral pharmacotherapy
a. Daily SSRIs; on demand clomipramine or dapoxetine (where available); and topical penile anaesthetics. Clinicians should recommend daily SSRIs; on demand clomipramine or dapoxetine (where available); and topical penile anaesthetics as first-line pharmacotherapies in the treatment of premature ejaculation. This is a strong recommendation according to evidence level: Grade B.
Define premature ejaculation and discuss the clinical evaluation of a patient with this condition.
Premature ejaculation is a condition characterized by poor ejaculatory control, associated bother, and ejaculation latency that is markedly reduced from prior sexual experience during penetrative sex. It is classified as either lifelong or acquired premature ejaculation. Lifelong premature ejaculation is present since sexual debut and acquired premature ejaculation is developed later in life.
When evaluating a patient with premature ejaculation, clinicians should assess their medical, relationship, and sexual history, as well as perform a focused physical exam. Validated instruments may be used to assist in the diagnosis of premature ejaculation. Additional testing is not recommended for the evaluation of a patient with lifelong premature ejaculation, but may be utilized for patients with acquired premature ejaculation if clinically indicated.
Clinicians may also consider referring patients to a mental health professional with expertise in sexual health, as combining behavioral and pharmacological approaches may be more effective than either modality alone. The first-line pharmacotherapy recommended in the treatment of premature ejaculation includes daily SSRIs, on demand clomipramine or dapoxetine (where available), and topical penile anaesthetics. If patients have failed first-line therapy, clinicians may consider on-demand dosing of tramadol or treating with α1-adrenoreceptor antagonists.
What is delayed ejaculation and what are the treatment options for this condition?
Delayed ejaculation is a condition characterized by the inability to achieve ejaculation or excessive latency of ejaculation despite adequate sexual stimulation and the desire to ejaculate. It is classified as either lifelong or acquired delayed ejaculation. Lifelong delayed ejaculation is present since sexual debut, while acquired delayed ejaculation is developed later in life.
Clinicians should assess the medical, relationship, and sexual history of patients with delayed ejaculation, as well as perform a focused physical exam. Additional testing may be utilized if clinically indicated. Patients diagnosed with lifelong or acquired delayed ejaculation may be referred to a mental health professional with expertise in sexual health.

A. Ejaculation occurring more than 1 hour after penetration
B. Ejaculation occurring more than 30 minutes after penetration
C. Ejaculation occurring more than 15 minutes after penetration
D. Ejaculation occurring more than 10 minutes after penetration
B. Ejaculation occurring more than 30 minutes after penetration
Explanation: DE is defined as a delay or inability to achieve ejaculation during sexual activity, despite adequate sexual stimulation.
What are the potential causes of premature ejaculation (PE)?
There are several potential causes of PE, including psychological factors such as anxiety, stress, or depression, as well as biological factors such as abnormal hormone levels, genetic predisposition, or inflammation of the prostate gland. Additionally, certain medications, drug and alcohol use, and other medical conditions such as diabetes or multiple sclerosis can also contribute to PE.
What are the potential treatment options for delayed ejaculation (DE)?
Treatment for DE may include both psychological and physical interventions. Behavioral therapies such as the squeeze technique or stop-start method can be effective in managing DE. In addition, medications such as antidepressants or phosphodiesterase-5 inhibitors may be used to address underlying psychological or physical causes. Alternative treatments such as acupuncture or herbal remedies have also been explored, although their effectiveness remains unclear. In some cases, referral to a specialist in sexual medicine or therapy may be necessary to achieve optimal outcomes.

Describe the sexual response cycle in men.
The sexual response cycle in men is a linear process of increasing sexual excitement, starting with desire and followed by arousal, climax, and resolution. Sexual climax in men consists of two distinct physiological events: orgasm and ejaculation. Orgasm is a sensation of intense pleasure, relaxation, or intimacy that accompanies peak sexual arousal, while ejaculation is antegrade expulsion of semen from the urethra.
What triggers ejaculation and what is the spinal ejaculation generator (SEG)?
Ejaculation is triggered by integration of tactile and non-tactile stimuli in the brain. At some set point of arousal, a centrally-mediated action potential is triggered leading to ejaculatory and/or orgasmic inevitability. The spinal ejaculation generator (SEG) is a structure responsible for integrating stimuli from peripheral and cerebral sources and triggering the ejaculatory reflex. Lesion of this structure is strongly associated with ejaculatory failure.
What are the two distinct phases of ejaculation?
The two distinct phases of ejaculation are emission and ejection. Emission is a centrally-mediated action characterized by closure of the bladder neck and contraction of smooth muscles throughout the seminal tract. The emission phase also includes secretion of seminal fluid into the proximal urethra. The second phase is ejection, a reflex driven by the somatic nervous system, specifically the pudendal nerve. Ejection is characterized by repeated contractions of the bulbospongiosus and ischiocavernous muscles leading to forceful expulsion of seminal fluid from the urethral meatus.
What are the medical and surgical interventions that can alter ejaculatory function?
Medical and surgical interventions that alter function of the prostate and/or bladder neck often have noticeable and bothersome effects on ejaculation. Specific examples include decreased ejaculate volume and force in men using alpha blockers or 5-alpha reductase inhibitors for management of benign prostatic hyperplasia (BPH). Surgical interventions for BPH tend to cause pronounced and difficult to resolve alterations in ejaculatory function. A number of novel procedural approaches to BPH have been developed due in part to dissatisfaction with ejaculatory outcomes associated with conventional surgical BPH treatments. Surgical removal of the prostate and seminal vesicles for prostate cancer typically results in marked reduction or complete absence of ejaculation as these organs are responsible for the vast majority of seminal volume. Radiation therapy for prostate cancer is also commonly associated with loss of antegrade ejaculation. Disruption of ejaculation is associated with changes in subjective experience of orgasm for some men.
What are the factors that influence the subjective experience of orgasm?
The quality and intensity of orgasm may be influenced by a variety of factors that are incompletely understood. Orgasm is a transient neurological state characterized by intense feelings of pleasure, relaxation, and intimacy. It is mediated by and experienced in the brain, whereas ejaculatory reflexes are mediated by the putative SEG, making the subjective experience of orgasm an integration of numerous brain centers. The ventral medulla appears to exert an inhibitory effect on the SEG. In general, dopaminergic and oxytocinergic activation stimulates ejaculation and orgasm whereas serotonergic and gamma-aminobutyric acid (GABA)-ergic activation opposes ejaculation and orgasm. Agonists of opioid receptors, principally mu subtypes, are also associated with impairment of ejaculatory and orgasmic response.
What is the role of galaninergic neurons in ejaculation?
a. They have no role in ejaculation.
b. They play a minor role in ejaculation.
c. They play a critical role in ejaculation.
d. It depends on the individual.
c. They play a critical role in ejaculation.
Explanation: Galaninergic neurons are responsible for integrating stimuli from peripheral and cerebral sources and triggering the ejaculatory reflex. Lesion of these structures is strongly associated with ejaculatory failure.
What are galaninergic neurons?
Galaninergic neurons are a type of nerve cell that produce galanin, a neuropeptide that plays a critical role in the regulation of various physiological processes, including ejaculation. In the context of ejaculation, galaninergic neurons are responsible for integrating stimuli from peripheral and cerebral sources and triggering the ejaculatory reflex. Lesion of these structures is strongly associated with ejaculatory failure. These neurons are arranged in columns within the central spinal cord, and some experts have described this structure as the “spinal ejaculation generator” (SEG).
Describe the sexual response cycle.
The sexual response cycle consists of four phases: excitement, plateau, orgasm, and resolution. During the excitement phase, there is an increase in heart rate, blood pressure, and respiration. This phase is characterized by the onset of sexual arousal. During the plateau phase, sexual arousal continues to increase, but at a slower rate. This phase is characterized by increased muscle tension and vasocongestion. During the orgasm phase, there is a release of sexual tension and a feeling of intense pleasure. This phase is characterized by rhythmic contractions of the genital organs. During the resolution phase, there is a return to the pre-aroused state.
How is ejaculation triggered?
Ejaculation is triggered by the integration of tactile and non-tactile stimuli in the brain. At some set point of arousal, a centrally-mediated action potential is triggered leading to ejaculatory and/or orgasmic inevitability. The presence of galaninergic neurons arranged in columns within the central spinal cord is critical in this process. These neurons are responsible for integrating stimuli from peripheral and cerebral sources and triggering the ejaculatory reflex. Lesion of these structures is strongly associated with ejaculatory failure.
What are the two distinct phases of ejaculation?
A. Emission and Orgasm
B. Orgasm and Ejection
C. Emission and Ejection
D. Ejection and Ejaculation
. Emission and Ejection
Explanation: Ejaculation consists of two distinct phases, emission and ejection. The first phase is emission, characterized by closure of the bladder neck and contraction of smooth muscles throughout the seminal tract, mediated by the sympathetic nervous system. The second phase is ejection, a reflex driven by the somatic nervous system, specifically the pudendal nerve.
Which nervous system mediates the emission phase of ejaculation?
A. Parasympathetic Nervous System
B. Somatic Nervous System
C. Sympathetic Nervous System
D. Autonomic Nervous System
C. Sympathetic Nervous System
Explanation: The emission phase of ejaculation is mediated by the sympathetic nervous system. It is characterized by closure of the bladder neck and contraction of smooth muscles throughout the seminal tract, as well as secretion of seminal fluid into the proximal urethra.
What is the role of Onuf’s nucleus in ejaculation?
Onuf’s nucleus is a cluster of motor neurons in spinal segments S2-4 that appears to be of particular import for control of the striated muscles of the pelvis during ejaculation. This includes the bulbospongiosus and ischiocavernous muscles that contract during the ejection phase of ejaculation, leading to forceful expulsion of seminal fluid from the urethral meatus. The somatic nervous system, specifically the pudendal nerve, is responsible for driving this reflex during the ejection phase.
Which of the following medical interventions for BPH is most likely to cause a decrease in ejaculate volume and force?
a. Antibiotics
b. Antidepressants
c. Alpha blockers
d. Anticoagulants
c. Alpha blockers
Explanation: Alpha blockers are commonly used to manage benign prostatic hyperplasia (BPH), but they can cause decreased ejaculate volume and force due to their effect on prostate function.
What surgical procedure for BPH is known to cause pronounced and difficult to resolve alterations in ejaculatory function?
a. Transurethral resection of the prostate (TURP)
b. Prostatectomy
c. Prostate biopsy
d. Cystectomy
a. Transurethral resection of the prostate (TURP)
Explanation: TURP is a conventional surgical treatment for BPH that can cause pronounced and difficult to resolve alterations in ejaculatory function. This has led to the development of novel procedural approaches to BPH.
Which organs are responsible for the vast majority of seminal volume?
a. Prostate and bladder neck
b. Seminal vesicles and prostate
c. Bladder neck and urethra
d. Urethra and seminal vesicles
b. Seminal vesicles and prostate
Explanation: The seminal vesicles and prostate are responsible for the vast majority of seminal volume. Surgical removal of these organs for prostate cancer typically results in marked reduction or complete absence of ejaculation.
How does disruption of ejaculation affect subjective experience of orgasm for some men?
Disruption of ejaculation is associated with changes in subjective experience of orgasm for some men. Ejaculation is a key part of the male sexual response cycle, and its disruption can lead to decreased or altered sensation of orgasm. For example, men who have undergone surgical removal of the prostate and seminal vesicles for prostate cancer often report a decrease or absence of orgasmic sensation. The psychological and emotional impact of these changes can also be significant, and may require counseling or therapy.
Which of the following statements about orgasm is true?
A. Orgasm is characterized by intense feelings of pain, stress, and loneliness.
B. There is little variability in the subjective experience of orgasm between individuals.
C. Orgasm is typically experienced at peak sexual arousal.
D. The refractory period tends to become shorter with increasing age.
C. Orgasm is typically experienced at peak sexual arousal. Orgasm is a transient neurological state characterized by intense feelings of pleasure, relaxation, and intimacy. It is typically experienced at peak sexual arousal, which can vary between individuals and within a given person at different times.
What is the refractory period?
A. The time period following sexual arousal during which orgasm is not possible.
B. The time period following orgasm during which arousal and sexual climax are not possible.
C. The time period following sexual arousal during which only one orgasm is possible.
D. The time period following orgasm during which sexual arousal is heightened.
B. The time period following orgasm during which arousal and sexual climax are not possible.
Explanation: In men, orgasm is typically followed by a refractory period during which arousal and sexual climax are not possible. The duration of the refractory period tends to become longer with increasing age.
Which brain regions are thought to be intimately involved in central integration of stimuli germane to ejaculatory response?
a. The stria terminalis
b. The posterodorsal area of the medial amygdala
c. The parvicellular part of the supraparafascicular thalamus
d. All of the above
d. All of the above
Explanation: The stria terminalis, the posterodorsal area of the medial amygdala, and the parvicellular part of the supraparafascicular thalamus are all thought to be intimately involved in central integration of stimuli germane to ejaculatory response.
What is the putative SEG?
The putative SEG (spinal ejaculation generator) is a group of neurons located in the lumbosacral spinal cord that are responsible for the ejaculatory reflex.
Explanation: Understanding the role of the SEG is important in understanding disorders of ejaculation, as these disorders may involve dysfunction of the SEG.
Which neurotransmitters generally stimulate ejaculation and orgasm?
A) Serotonergic and GABA-ergic activation
B) Dopaminergic and oxytocinergic activation
C) Agonists of opioid receptors
D) None of the above
B) Dopaminergic and oxytocinergic activation
Explanation: In general, dopaminergic and oxytocinergic activation stimulates ejaculation and orgasm.
Which opioid receptor subtype is primarily associated with impairment of ejaculatory and orgasmic response?
A) Kappa
B) Delta
C) Mu
D) None of the above
C) Mu
Explanation: Agonists of opioid receptors, principally mu subtypes, are associated with impairment of ejaculatory and orgasmic response.
How do serotonergic and GABA-ergic activation oppose ejaculation and orgasm?
Serotonergic and GABA-ergic activation generally oppose ejaculation and orgasm. Serotonin is involved in mood regulation and is associated with feelings of calm and contentment, while GABA is the main inhibitory neurotransmitter in the brain. Activation of these neurotransmitters can decrease sexual arousal and inhibit ejaculation and orgasm.
Which of the following hormones is necessary for the initial maturation of sexual, including ejaculatory, reflexes?
a. Estrogen
b. Progesterone
c. Androgens
d. Prolactin
c. Androgens
Explanation: Experimental and observational data in animals and humans indicate that androgens are necessary for at least the initial maturation of sexual, including ejaculatory, reflexes.
What is the significance of galaninergic neurons in the L3 and L4 spinal segments in males?
a. They are not related to the ejaculatory process.
b. They suggest a sexually dimorphic developmental pathway.
c. They are responsible for the production of androgens.
d. They have no role in the sexual response cycle.
b. They suggest a sexually dimorphic developmental pathway.
Explanation: Male cadavers had a greater density of galaninergic neurons in the L3 and L4 spinal segments as compared to female cadavers, suggesting a sexually dimorphic developmental pathway likely mediated by differential exposure to androgens.
What is the significance of galaninergic neurons in the ejaculatory process?
Galaninergic neurons in the L3 and L4 spinal segments are thought to be essential to the ejaculatory process as evidenced by frequency of failure to ejaculate in response to penile vibratory stimulation in men with L3-5 spinal cord injury. These neurons are part of the putative SEG (spinal ejaculatory generator), which is responsible for the coordination of the motor activity necessary for ejaculation. The density of these neurons is greater in male cadavers as compared to female cadavers, suggesting a sexually dimorphic developmental pathway likely mediated by differential exposure to androgens.
Which of the following statements about serum testosterone levels is true?
a) Serum testosterone levels represent peripheral action of T in the tissues.
b) Variations in androgen receptor function do not affect the final action of T within target tissues.
c) Intracellular trafficking of T bound to the androgen receptor does not affect the final action of T within target tissues.
d) The balance among modulators of T receptors does not affect the final action of T within target tissues.
Answer: d) The balance among modulators of T receptors does not affect the final action of T within target tissues.
Serum testosterone levels do not represent peripheral action of T in the tissues, where T acts. Variations in androgen receptor function (e.g., number of CAG repeats), intracellular trafficking of T bound to the androgen receptor, and the balance among modulators of T receptors determine the final action of T within target tissues.
Which type of receptors carry out T action in the CNS?
a) Non-nuclear receptors only
b) Nuclear receptors only
c) Both nuclear and non-nuclear receptors
d) Neither nuclear nor non-nuclear receptors
Answer: c) Both nuclear and non-nuclear receptors
: T action in the CNS is carried out by nuclear receptors and possibly by non-nuclear G-protein coupled receptors.
How do variations in androgen receptor function affect T action within target tissues?
Variations in androgen receptor function, such as the number of CAG repeats, can affect T action within target tissues by altering the receptor’s sensitivity to T. This can result in different levels of T activity in different tissues, even when serum T levels are the same. Additionally, variations in intracellular trafficking of T bound to the androgen receptor and the balance among modulators of T receptors can also affect the final action of T within target tissues.
What is a common cause of disruption in ejaculation or orgasm?
a. Lack of sleep
b. Lack of exercise
c. Lack of sexual desire and/or erectile dysfunction
d. Lack of communication in a relationship
c. Lack of sexual desire and/or erectile dysfunction
Explanation: According to the guideline statements, one of the common causes of disruption in ejaculation or orgasm is failure of the earlier elements of sexual response such as lack of sexual desire and/or erectile dysfunction leading to inadequate genital and subjective excitement.
What condition can impair the subjective experience of orgasm but preserve ejaculatory reflexes?
a. Neurological lesions of the sympathetic nervous system
b. Retroperitoneal lymph node dissection
c. Cerebral lesions
d. Transurethral resection of the prostate
: c. Cerebral lesions
Explanation: According to the guideline statements, it is possible for ejaculatory reflexes to be preserved in the context of psychological, cerebral, or other neurologic lesions that may impair the subjective experience of orgasm.

A. Chronicity and time of onset
B. Frequency of disturbance
C. Negative interpersonal consequences
D. Inability to delay ejaculation on all or nearly all vaginal penetrations
A. Chronicity and time of onset
What are the criteria for the diagnosis of premature ejaculation according to DSM-V?
According to DSM-V, premature ejaculation is diagnosed as a persistent or recurrent pattern of ejaculation occurring during partnered sexual activity within approximately 1 minute following vaginal penetration and before the individual wishes it. The disorder must be present in 75% or more of sexual encounters and persistent over at least the last 6 months. To qualify as a dysfunction, the man must experience personal distress related to the dysfunction and the condition cannot be better explained by a comorbid or concomitant diagnosis.
What is the strongest definition of premature ejaculation in terms of evidence basis?
he definition of premature ejaculation by the International Society of Sexual Medicine (ISSM) is the strongest in terms of evidence basis. The robust evidence basis is also a limitation in that the data used in its development were derived from studies of vaginal intercourse and hence it is explicitly specific to coitus.
What sub-types of premature ejaculation are recognized by the DSM-V?
A. Lifelong and acquired
B. Generalized and situational
C. Severe, moderate, and mild
D. All of the above
D. All of the above
Explanation: The DSM-V recognizes four sub-types of premature ejaculation - lifelong, acquired, generalized, and situational. Additionally, ejaculation that occurs before penetration or within 15 seconds, between 15-30 seconds after penetration, and from 30-60 seconds after penetration are categorized as severe, moderate, or mild PE, respectively.
What is the definition of premature ejaculation according to the ISSM?
A) Ejaculation that always occurs prior to vaginal penetration
B) A clinically significant and bothersome reduction in latency time, often to about 5 minutes or less
C) Ejaculation that occurs within 2 minutes of vaginal penetration
D) Ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE)
D) Ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE). This definition is to date the strongest in terms of evidence basis.
