It is caused by failure of semen emission from the seminal vesicles, prostate and ejaculatory ducts into the urethra [232]. True anejaculation is usually associated with a normal orgasmic sensation. True anejaculation is always associated with central or peripheral nervous system dysfunction or with drugs [233] (Table 6). 3L.1.2 Anorgasmia Anorgasmia is the inability to reach orgasm and can give rise to anejaculation. Anorgasmia is often a primary condition and its cause is usually psychological. 3L.1.3 Delayed ejaculation In delayed ejaculation, abnormal stimulation of the erect penis is needed to achieve orgasm with ejaculation [232]. Delayed ejaculation can be considered a mild form of anorgasmia. The causes of delayed ejaculation can be psychological, organic (e.g. incomplete spinal cord lesion [234] or iatrogenic penile nerve damage [235]), or pharmacological (e.g. selective serotonin re-uptake inhibitors (SSRIs), antihypertensives, or antipsychotics) [236]. 3L.1.4 Retrograde ejaculation Retrograde ejaculation is the total, or sometimes partial, absence of antegrade ejaculation as a result of semen passing backwards through the bladder neck into the bladder. Patients experience a normal or decreased orgasmic sensation. The causes of retrograde ejaculation can be divided into neurogenic, pharmacological, urethral, or bladder neck incompetence (Table 6). Table 6: Aetiology of anejaculation and retrograde ejaculation Neurogenic Pharmacological Spinal cord injury Antihypertensives Cauda equina lesions α1-adrenoceptor antagonists Multiple sclerosis Antipsychotics and antidepressants Autonomic neuropathy (diabetes mellitus) Alcohol Retroperitoneal lymphadenectomy Sympathectomy or aortoiliac surgery Colorectal and anal surgery Parkinson´s disease Urethral Bladder neck incompetence Ectopic ureterocele Congenital defects/dysfunction of hemitrigone Urethral stricture Bladder extrophy Urethral valves or verumontaneum hyperplasia Bladder neck resection (transurethral resection of the Etiologies prostate) Congenital dopamine b-hydroxylase deficiency Prostatectomy 3L.1.5 Asthenic ejaculation Asthenic ejaculation is characterised by an altered propulsive phase, with a normal emission phase [236]. The orgasmic sensation is reduced and the typically rhythmical contractions associated with ejaculation are missing. Asthenic ejaculation does not usually affect semen quality. 3L.1.6 Premature ejaculation The International Society for Sexual Medicine (ISSM) has adopted the first evidence-based definition of lifelong premature ejaculation (PE): “Premature ejaculation is a male sexual dysfunction characterised by ejaculation which always or nearly always occurs prior to or within about one minute of vaginal penetration; and inability to delay ejaculation on all or nearly all vaginal penetrations; and negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy”. Premature ejaculation may be strictly organic (e.g., prostatitis-related) or psychogenic, partner-related or non-selective, and can be associated with MALE INFERTILITY - UPDATE MARCH 2014 29 EAU guidelines LIFE 2015 Ejaculatory dysfunction after surgery Iatrogenic after surgery • Cystoprostatectomy ¡ Bladder cancer • Radical prostatectomy ¡ Prostate Cancer • Endoscopic and simple prostatectomy ¡ BPH • Retroperitoneal ¡ Lymphadenectomies ¡ Aortic surgery ¡ Sigmoid and rectal surgery • EBR, Brachytherapy (Prostate cancer) ¡ Anejaculation 90% at 5 y ¡ IIEF-O: 7,4 to 2,8/10 at 3 y Sulivan JF et al J Sex Med 2013 LIFE 2015 Retroperitoneal lymphadenectomy Ao VRG L1 L2 L3 VCI Uretère Rein Dt Psoas LIFE 2015 Sexual dysfunctions after rectal surgery 100 90 80 70 60 50 Tous 40 AAP 30 20 Résection Antérieure 10 Excison trans-anale 0 Hendren et al Ann Surg 2005 LIFE 2015 Sexual dysfunctions after rectal surgery 100 90 80 70 60 50 Tous 40 AAP 30 20 Résection Antérieure 10 Excison trans-anale 0 Hendren et al Ann Surg 2005 LIFE 2015 Drug side effects on ejaculation Drug induced ejaculatory dysfunction • Delayed or suprressed ejaculation ¡ Alphablokers ¡ Antiandrogens ¡ Antidepressants ¡ Analgesic, Baclofen ¡ Antipsychotics, lithium ¡ Antihypertensive (alpha or betablockers and central) ¡ Cytotoxics (methotrexate, vincristine) ¡ Antiparkinsonians (bromocryptine) ¡ Recreational rugs except amphetamin and heroïne ¡ Alcoolism LIFE 2015 Alpha-blockers • Anejaculation ¡ Silodosin> Tamsulosin> Alfusosin ¡ Anejaculation: ¡ 100% of healthy volunteers with silodosin (Kobayashi et al.
