Anejaculation and Retrograde Ejaculation

Application of the sexual therapy combined with vacuum negative pressure hydropneumatic/pneumatic bubble massage in primary intravaginal anejaculation

INTRODUCTION

Primary intravaginal anejaculation (PIAJ) is a relatively uncommon male sexual dysfunction characterized by an inability to achieve intravaginal ejaculation during all sexual intercourse. Effective treatment options for this condition are lacking. We aimed to explore the clinical effect of the sexual therapy combined with vacuum negative pressure hydropneumatic/pneumatic bubble massage (VNPHP/PBM) on primary intravaginal anejaculation, and its possible mechanism.

METHODS

A total of 95 PIAJ patients were randomly divided into three groups, including group A with 32 patients treated with the sexual therapy combined with VNPHP/PBM, group B with 32 patients treated with the sexual therapy and group C with 31 patients treated with VNPHP/PBM. The efficacy of therapeutic regimes, latency of the somatosensory evoked potentials of dorsal nerve (DNSEP), glans penis (GPSEP) and penile shaft sensory threshold (PSST), measures of sexual behavior of patients, as well as the self-rating anxiety scale (SAS) sores of patients and their partners, were compared before and after treatment among three groups.

RESULTS

The total effective rate of group A (84.38%) was higher than those of groups B and C (53.13% and 41.94%), however, no differences were found between groups B and C. The ratios of patients and their partners with anxiety, frequency of observing erotic films of patients, ratios of patients with special self-masturbation and frequency of masturbation decreased significantly in the three groups after the treatment. The decrease in the ratios of patients and their partners with anxiety, frequency of observing erotic films of patients in groups A and B were higher than those of group C, however, no differences were identified between groups A and B. The decrease in the ratios of patients with special self-masturbation and frequency of masturbation in group A were higher than those of group B, however, no differences were found between groups A and C, B and C. There were no differences in the latency of DNSEP, GPSEP, and PSST among the three groups before and after treatment.

CONCLUSION

The sexual therapy combined with VNPHP/PBM has good therapeutic effects on PIAJ, which might be achieved by reducing the anxiety level of patients and their partners, improving sexual behavioral patterns, rather than increasing the sensitivity of penis including dorsal nerve and glans penis.

Pseudoephedrine for ejaculatory dysfunction after retroperitoneal lymph node dissection in testicular cancer

OBJECTIVE

To assess the impact of ejaculatory dysfunction (EjD; failure of emission or retrograde ejaculation) on health-related quality of life (HRQoL) after retroperitoneal lymph node dissection (RPLND) for testicular cancer and explore the efficacy of pseudoephedrine hydrochloride as treatment.

PATIENTS AND METHODS

In a single arm, phase II trial, patients at ≥6 months after RPLND were invited to complete patient-reported outcome measures (European Organisation for Research and Treatment of Cancer [EORTC] quality of life questionnaire [QLQ]-30-item core, EORTC QLQ-testicular cancer-26, and Brief Male Sexual Function Inventory) evaluating HRQoL and sexual function in follow-up (ACTRN12622000537752/12622000542796). If EjD was reported, post-ejaculatory urine ± semen analysis was undertaken. In eligible patients, pseudoephedrine hydrochloride 60 mg was administered orally every 6 h for six doses. The primary endpoint was sperm count >39 million sperm/ejaculate (>5th centile) following treatment. The trial was powered to detect a clinically relevant 36% achieving sperm count of >39 million sperm/ejaculate. Secondary endpoints included semen volume >1.5 mL, total motile sperm count, safety, and HRQoL impacts.

RESULTS

Of the 58 patients enrolled, the median (interquartile range [IQR]) age was 35 (29-41) years, with a median (IQR) of 37 (18-60) months from RPLND. EjD was reported in 33 (57%), including 27/52 (52%) receiving follow-up at our centre. There were no differences in global HRQoL; however, role functioning (P = 0.045), sexual problems (P < 0.005), and sexual enjoyment (P = 0.005) was poorer if EjD was present. In all, 24/33 (73%) patients with EjD consented to pseudoephedrine treatment. Of 22 evaluable patients, four (18%) achieved a sperm count of >39 million/ejaculate (P = 0.20), and four (18%) had a semen volume of >1.5 mL (P = 0.20). There was a mean increase of 105 million sperm/ejaculate (P = 0.051) and 1.47 mL increase in semen volume (P = 0.01). No safety concerns arose.

CONCLUSION

Ejaculatory dysfunction is common after RPLND but did not impact global HRQoL in our cohort. Pseudoephedrine improved EjD for some; however, its efficacy was lower than expected. Pseudoephedrine may be considered on an individualised basis.

A rare cause of anejaculation: mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) syndrome: case report

Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) syndrome is an extremely rare multisystem disorder with autosomal recessive inheritance and impairs mitochondrial DNA replication, which causes myopathy and neurodegeneration. The classical symptoms of this syndrome are progressive gastrointestinal dysmotility and peripheral neuropathy. We are presenting a patient who had MNGIE syndrome and presented with anejaculation for the first time in the literature. A 27-year-old male patient applied to the urology clinic with anejaculation. It was learned that the patient had lifelong anejaculation and had no problems with libido, erection, or orgasm from his sexual history. In the evaluation of the etiology of anejaculation, the patient did not have any known causes of anejaculation. From the patient's medical history, it was learned that he was diagnosed with MNGIE syndrome when he presented to another hospital with gastrointestinal symptoms 5 years ago. Neurodegenerative diseases are the potential cause of anejaculation due to sensorimotor neuropathy and paresthesia. The patient was given genetic counseling and was informed about assisted reproductive techniques and that his partner should be screened for MNGIE syndrome. In conclusion, when evaluating neurodegenerative diseases, it is of great importance to question the patients' sexual problems, which are important for their quality of life, and to provide appropriate counseling.

Efficacy of Neuromodulation Interventions for the Treatment of Sexual Dysfunction: A Systematic Review

OBJECTIVES

The primary aim of this review was to analyze the literature for the efficacy of neuromodulation interventions in treating both male and female sexual dysfunction.

MATERIALS AND METHODS

Studies were identified from PubMed, Scopus, PsychINFO, CINAHL, and Cochrane. Results were synthesized qualitatively without pooling owing to the heterogeneous nature of outcome assessments.

RESULTS

Overall findings from studies generally supported that neuromodulation interventions were associated with improvement in sexual function. Specific domains that improved in male patients included erectile function, desire, and satisfaction, whereas desire, arousal, orgasm, lubrication, quality of "sex life," intercourse capability, and dyspareunia improved in female patients. Male ejaculation, orgasm, and intercourse capability were the only domains that continued to decline after the use of neuromodulation interventions, although this was only reported in one study.

CONCLUSION

Our review suggests that there may be promise and potential utility of neuromodulation in improving sexual dysfunction; however, further research is needed.

The erectile and ejaculatory implications of the surgical management of rectal cancer

Colorectal cancer is a significant cause of cancer-related deaths worldwide. Although advances in surgical technology and technique have decreased mortality rates, surviving patients often experience sexual dysfunction as a common complication. The development of the lower anterior resection has greatly decreased the use of the radical abdominoperineal resection surgery, but even the less radical surgery can result in sexual dysfunction, including erectile and ejaculatory dysfunction. Improving the knowledge of the underlying causes of sexual dysfunction in this context and developing effective strategies for preventing and treating these adverse effects are essential to improving the quality of life for postoperative rectal cancer patients. This article aims to provide a comprehensive evaluation of erectile and ejaculatory dysfunction in postoperative rectal cancer patients, including their pathophysiology and time course and strategies for prevention and treatment.

How Well Do Semen Analysis Parameters Correlate with Sperm DNA Fragmentation? A Retrospective Study from 2567 Semen Samples Analyzed by the Halosperm Test

Sperm DNA fragmentation (SDF) levels have been measured in the workup for in vitro fertilization (IVF) at PIVET since 2007, with the Halosperm test having replaced the previous sperm chromatin structure assay (SCSA) since 2013. Of 2624 semen samples analyzed for the Halosperm test, 57 were excluded as the sperm concentration was <5 million/mL, a level too low for accurate testing, leaving 2567 samples for assessment within this study. The SDF rates were categorized in 5 sperm DNA fragmentation indices (DFI), ranging from <5% to levels >30%, and these categories were correlated with the respective semen analysis profiles and two clinical parameters, namely the age of the male and the ejaculatory abstinence period prior to the sample. The results showed a significant correlation with male age (r = 0.088; p < 0.0001), the abstinence period (r = 0.076; p = 0.0001), and the semen volume (r 0.063; p = 0.001), meaning an adversely high SDF was associated with advanced age, prolonged abstinence, and raised semen volume parameters. There was a significant negative correlation with sperm morphology (r = −0.074; p = 0.0001), progressive motility (r = −0.257; p < 0.0001), and semen pH (r = −0.066; p < 0.001), meaning these semen anomalies were associated with high SDF values. With respect to abnormal morphology, sperm tail defects had a positive correlation (r = 0.096; p < 0.0001) while midpiece defects showed a negative correlation (r = −0.057; p = 0.004), meaning that tail defects are most likely to associate with adverse DFI values. With respect to motility patterns, the poorer patterns showed a positive correlation with increased DFI, namely C pattern (r = 0.055; p = 0.005) and D pattern (r = 0.253; p < 0.0001). These results imply that raised DFI reflects poor sperm quality and should be investigated in clinical trials involving IVF and the consideration of intracytoplasmic sperm injection (ICSI).

Ejaculation: the Process and Characteristics From Start to Finish

Purpose of Review

Semen analysis serves as the initial step in the evaluation of male infertility. However, given the difficulty in interpreting abnormal findings, physicians and patients often struggle with understanding the results. In this review, we aim to review the normal physiology of ejaculation and create an accessible resource for interpreting abnormal semen volume, viscosity, liquefaction, pH, appearance, and color.

Recent Findings

Emerging evidence has revealed that men with genitourinary tract infections have a greater number of seminal leukocytes, which may result in clumping of motile sperm and altered morphology. Hence, these patients may have abnormal sperm parameters secondary to their health status. Recent findings have further characterized the semen liquefaction process, suggesting that increased levels of semenogelin and decreased levels of proteases and plasminogen activators (e.g., urokinase and chymotrypsin) may be associated with the failure of semen to convert to a watery consistency.

Summary

This article creates a resource which may be referenced when abnormalities in semen analysis are encountered. We offer a comprehensive overview of normal ejaculation physiology and abnormal variants in male ejaculate volume-including aspermia, anejaculation, retrograde ejaculation, and hypo- and hyperspermia-and their potential etiologies. Additionally, we discuss several processes (infection, inflammation, and dysfunction of male sex glands) which may affect semen viscosity, liquefaction, and pH. Finally, our discussion of the potential colors of male ejaculate is meant to reduce the anxiety of both patient and provider. Through a better understanding of the process and varying characteristics of ejaculation, physicians may adequately counsel their patients on abnormal findings and concerns regarding infertility.

The male infertility evaluation still matters in the era of high efficacy assisted reproductive technology

Today's reproductive endocrinology and infertility providers have many tools at their disposal when it comes to achieving pregnancy. In the setting of highly efficacious assisted reproductive technology, it is natural to assume that male factor infertility can be overcome by acquiring sperm and then bypassing the male evaluation. In this review, we go through guideline statements and a stepwise male factor infertility evaluation to propose that a thorough male evaluation remains important to optimize pregnancy and live birth. The foundation of this parallel evaluation is referral to a reproductive urologist for the optimization of the male partner, for advanced diagnostics and interventions, and for the detection of other underlying male pathology. We also discuss what future developments might have an impact on the workup of the infertile male.

Proteomic insight of seminal plasma in spinal cord injured men submitted to oral probenecid treatment for improved motility

OBJECTIVE

To observe the seminal plasma proteomic composition in men with spinal cord injury orally treated with probenecid, in order to observe pathways associated with increased sperm motility.

STUDY DESIGN

Prospective study.

SETTING

Miami Project to Cure Paralysis - University of Miami/Miller School of Medicine.

PARTICIPANTS

Nine men with spinal cord injury, who agreed to participate in the study.

INTERVENTION

Oral treatment with probenecid - 500 mg per day for one week, then 500 mg twice daily [1000 mg total] per day for three weeks.

OUTCOME MEASURES

Semen analysis as per WHO 2010 guidelines, and seminal plasma proteomics analysis by LC-MS/MS.

RESULTS

In total, 783 proteins were identified, of which, 17 were decreased, while 6 were increased after treatment. The results suggest a new pathway that could be treated by the decrease of biglycan after probenecid treatment.

CONCLUSION

Oral treatment with probenecid is able to alter the seminal plasma proteome, in pathways that explain decreased innate immune response.

Fertility preservation in men: a contemporary overview and a look toward emerging technologies

Cancer and oncologic therapies can have significant adverse effects on male reproductive potential, leaving many men permanently infertile. Fertility preservation has emerged as a key survivorship issue over the past 20 years, and numerous professional societies have published guidelines calling for fertility preservation to become a routine component of oncologic care. Most males with cancer are able to produce a semen specimen for fertility preservation, but numerous other methods of sperm procurement are available for patients who cannot provide a sufficient sample. Despite these options, fertility preservation will remain a challenge for prepubertal boys and men without sperm production. For these patients, experimental and investigational approaches offer the hope that one day they will translate to the clinical arena, offering additional pathways for successful fertility preservation care.

Longitudinal muscular column in the prostatic urethral wall: Its form, shape, and possible function based on mathematical simulation in ejaculation

BACKGROUND

The shape and function of the longitudinal muscular column (LMC) of the prostate have not been established in detail. The present study was undertaken to elucidate the roles of the LMC of the posterior wall of the prostatic urethra (PSU) in the emission phase of ejaculation by investigating the form and muscular arrangement of the LMC.

METHODS

Prostates and urinary bladders were obtained from 14 Korean adult cadavers. Nine specimens were histologically analyzed using hematoxylin and eosin, Masson's trichrome, and Verhoeff-van Gieson staining. Two specimens were scanned using microcomputed tomography (micro-CT), and all scanned images were reconstructed into a three-dimensional model.

RESULTS

At the proximal level of the prostate, the ejaculatory ducts (EDs) and prostatic utricle (PU) together were surrounded by circular smooth-muscle fibers. However, at the seminal colliculus (SC) where the EDs and PU opened, they were mainly surrounded by an abundance of longitudinal fibers. The longitudinal fibers posterior to the EDs and PU formed a distinctive LMC in the posterior urethral wall. In histologic sections and micro-CT images, the LMC extended distally from the level of the SC to the level of the membranous urethra (MBU). We simulated a potential mechanism of LMC using a mathematical model of its movements.

CONCLUSIONS

Comprehensive analyses based on in-depth assessment of histologic characteristics and micro-CT images demonstrated extension of the LMC from the level of the SC to the level of the MBU, enabling a better understanding of ejaculation physiology involving the LMC. These results suggest that the LMC in the posterior wall of the PSU is a critical component of ejaculation by facilitating the ejection of seminal vesicle fluid into the PSU via well-coordinated contractions.

Sexual dysfunction and male infertility

Infertility affects up to 12% of all men, and sexual dysfunction occurs frequently in men of reproductive age, causing infertility in some instances. In infertile men, hypoactive sexual desire and lack of sexual satisfaction are the most prevalent types of sexual dysfunction, ranging from 8.9% to 68.7%. Erectile dysfunction and/or premature ejaculation, evaluated with validated tools, have a prevalence of one in six infertile men, and orgasmic dysfunction has a prevalence of one in ten infertile men. In addition, infertile men can experience a heavy psychological burden. Infertility and its associated psychological concerns can underlie sexual dysfunction. Furthermore, general health perturbations can lead to male infertility and/or sexual dysfunction. Erectile dysfunction and male infertility are considered proxies for general health, the former underlying cardiovascular disorders and the latter cancerous and noncancerous conditions. The concept that erectile dysfunction in infertile men might be an early marker of poor general health is emerging. Finally, medications used for general health problems can cause sperm abnormalities and sexual dysfunction. The treatment of some causes of male infertility might improve semen quality and reverse infertility-related sexual dysfunction. In infertile men, an investigation of sexual, general, and psychological health status is advisable to improve reproductive problems and general health.

Improvement of Sexual and Reproductive Function in Men with Spinal Cord Lesion

SUMMARY – The aim of the review is to establish sexual and reproductive functions in men with spinal cord lesion (SCL). Many sexual and reproductive dysfunctions may be found in these patients including individual’s low self-esteem, delay of orgasm, erectile or ejaculatory disorder and abnormalities of semen, which are characterized by lower sperm motility or viability. Owing to improvements in physical medicine and rehabilitation, the focus has been shifted from keeping patients alive towards ensuring the quality of life and improvements of sexual dysfunctions and later reproduction. Erectile dysfunction can be treated by using phosphodiesterase-5 inhibitors, intracavernosal injections, vacuum devices and penile prostheses. Semen can be retrieved from anejaculatory patients by medically assisted methods utilizing penile vibratory stimulation, electroejaculation, prostate massage, or surgically. Although there is low chance for pregnancy in natural way in most of SCL patients, fatherhood is possible through the introduction of assisted medical management. By use of various medical, technical and surgical procedures for sperm retrieval combined with assisted reproductive methods, high pregnancy rates have been reported comparable to those in able-bodied subfertile patients. Nevertheless, future studies are needed to improve semen quality and methods of assisted ejaculation in patients with SCL.

Delayed Ejaculation: Pathophysiology, Diagnosis, and Treatment

Delayed ejaculation (DE) is a poorly defined and uncommon form of male sexual dysfunction, characterized by a marked delay in ejaculation or an inability to achieve ejaculation. It is often quite concerning to patients and their partners, and sometimes frustrates couples' attempts to conceive. This article aims to review the pathophysiology of DE and anejaculation (AE), to explore our current understanding of the diagnosis, and to present the treatment options for this condition. Electronic databases were searched from 1966 to October 2017, including PubMed (MEDLINE) and Embase. We combined “delayed ejaculation,” “retarded ejaculation,” “inhibited ejaculation,” or “anejaculation” as Medical Subject Headings (MeSH) terms or keywords with “epidemiology,” “etiology,” “pathophysiology,” “clinical assessment,” “diagnosis,” or “treatment.” Relevant sexual medicine textbooks were searched as well. The literature suggests that the pathophysiology of DE/AE is multifactorial, including both organic and psychosocial factors. Despite the many publications on this condition, the exact pathogenesis is not yet known. There is currently no single gold standard for diagnosing DE/AE, as operationalized criteria do not exist. The history is the key to the diagnosis. Treatment should be cause-specific. There are many approaches to treatment planning, including various psychological interventions, pharmacotherapy, and specific treatments for infertile men. An approved form of drug therapy does not exist. A number of approaches can be employed for infertile men, including the collection of nocturnal emissions, prostatic massage, prostatic urethra catheterization, penile vibratory stimulation, probe electroejaculation, sperm retrieval by aspiration from either the vas deferens or the epididymis, and testicular sperm extraction.

Efficacy of treatment with pseudoephedrine in men with retrograde ejaculation

The use of pseudoephedrine, an alpha agonist, for the treatment of retrograde ejaculation is well-known, however, there is no clear consensus from the literature regarding its efficacy and treatment protocol. We evaluated the efficacy of pseudoephedrine treatment in patients with retrograde ejaculation, utilizing a yet undescribed short-period treatment protocol. Twenty men were medically treated with pseudoephedrine for retrograde ejaculation between January 2010 and May 2016 (12 with complete retrograde ejaculation and 8 with partial retrograde ejaculation). All patients had a semen analysis and post-ejaculatory urinalysis before and after treatment. The treatment protocol consisted of 60 mg of pseudoephedrine every 6 h on the day before semen analysis and two more 60 mg doses on the day of the semen analysis. Diabetes was the most common etiology for complete retrograde ejaculation (60%), whereas an idiopathic cause was the most common etiology for partial retrograde ejaculation (82%). Of the 12 complete retrograde ejaculation patients treated with pseudoephedrine prior to semen analysis, 7 (58.3%) recovered spermatozoa in the antegrade ejaculate, with a mean total sperm count of 273.5 ± 172.5 million. Of the eight patients with partial retrograde ejaculation, five (62.5%) had a ≥50% increase in the antegrade total sperm count. In this group, the mean total sperm count increased from 26.9 ± 8.5 million before treatment to 84.2 ± 24.6 million after treatment, whereas the percentage of spermatozoa in the urine declined from 43.2 ± 9% to 17 ± 10%, respectively (both p < 0.05). Overall, in men with retrograde ejaculation treated with a pseudoephedrine regimen prior to ejaculation, some improvement in seminal parameters occurred in 14 (70%) patients, with 10 patients (38.5% of all patients) achieving antegrade total sperm counts over 39 million.

Prostatic urethra malformation associated with retrograde ejaculation: a case report

Background

Retrograde ejaculation can have anatomical, neurogenic, or pharmacological causes. Among these factors, malformation of the prostatic urethra is an uncommon cause.

Case presentation

We describe a 29-year-old Han Chinese man with absence of his verumontanum combined with ejaculatory duct cysts, and no other cause for ejaculatory dysfunction. His verumontanum was replaced by a deep groove adjacent to his bladder neck, which could significantly influence bladder neck contraction. In addition, the large cysts in the ejaculatory duct could obstruct the anterior outlet of his prostatic urethra and prevent seminal fluid flow in an anterograde direction.

There are few reports of retrograde ejaculation associated with congenital malformations of the posterior urethra. Malformations associated with bladder neck laxity and increased tone of the prostatic urethral outlet can contribute to retrograde ejaculation.

Conclusions

Malformation of the prostatic urethra is an uncommon cause of retrograde ejaculation, and can be difficult to treat.

Fertility in men with spinal cord injury

Young men comprise the overwhelming majority of men with spinal cord injury (SCI), the incidence of which has been growing over the years. Due to advances in physical medicine and rehabilitation, remarkable improvements in survival rates have been reported, leading to life expectancies similar to those of the general population. However, many sexual and reproductive functions may be impaired due to erectile or ejaculatory dysfunction and semen abnormalities, characterised by low-sperm motility or viability in SCI males who have not become parents yet. Nevertheless, fatherhood is still possible through the introduction of specialised medical management, by using various medical, technical and surgical methods for sperm retrieval in combination with assisted reproductive techniques. Erectile dysfunction can be managed by the use of phosphodiesterase-5 inhibitors, intracavernosal injections, vacuum devices and penile prostheses. Semen can be obtained from the vast majority of anejaculatory men by medically assisted ejaculation through the use of penile vibratory stimulation or electroejaculation and via prostate massage or surgical procedures. Despite impaired sperm parameters, reasonable pregnancy rates similar to those in able-bodied subfertile cohorts have been reported. However, future research should focus on the optimisation of semen quality in these men and on improving natural ejaculation.

A step-wise approach to sperm retrieval in men with neurogenic anejaculation

Normal fertility is dependent on intravaginal delivery of semen through ejaculation. This process is highly dependent on an intact ejaculatory reflex arc, which can be disrupted through any type of trauma or disease causing damage to the CNS and/or peripheral nerves. Neurogenic anejaculation is most commonly associated with spinal cord injury. This aetiology is especially relevant because most men with spinal cord injuries are injured at reproductive age. Assisted ejaculation in the form of penile vibratory stimulation is the first choice for sperm retrieval in such patients because it is noninvasive and inexpensive. In patients in whom vibratory stimulation fails, electroejaculation is almost always successful. When both methods of assisted ejaculation are unsuccessful, sperm retrieval by aspiration from either the vas deferens or the epididymis, or by testicular biopsy or surgery are reasonable options. In such cases the most inexpensive and least invasive methods should be considered first. The obtained semen can be used for intravaginal or intrauterine insemination or in vitro fertilization with or without intracytoplasmic sperm injection.

Fertility Preservation in Young Men Treated for Malignancies: Options for Precancer Treatment

INTRODUCTION

Fertility preservation (FP) is an essential component of treatment for young men with a new cancer diagnosis.

AIM

To discuss the barriers and recommendations for FP along with the impacts of cancer and cancer treatment on fertility, and to present the various options for FP in young men prior to cancer treatment.

METHODS

Literature Review.

MAIN OUTCOME MEASURE

To evaluate the options for FP in young men, including novel and experimental options for pre-pubertal boys.

RESULTS

With the advent of assisted reproductive technologies, fertility can be successfully preserved in the majority of post-pubertal patients with sperm cryopreservation, neurostimulatory methods of ejaculation, or surgical sperm retrieval procedures.

CONCLUSIONS

All men with a new diagnosis of cancer, including adolescents and children, should be offered FP prior to undergoing treatment. Sperm cryopreservation, the mainstay of FP, should be encouraged regardless of the treatment plan. Even without significant abnormalities on semen analysis, prompt referral to a male fertility specialist is recommended. Coward RM, Kovac JR, Smith RP, and Lipshultz LI.

Clinical Background of Patients with Sperm in Their Urinary Sediment

Introduction

The detection rate and associated factors of at least one sperm in urinary sediment is not well-known in real clinical practice.

Aims

The aim of the present study was to evaluate the clinical features associated with the presence of sperm in urinary sediment in a large number of samples.

Methods

We conducted a cross-sectional study at Tokyo Saiseikai Central Hospital. We identified 5,005 males who were aged ≥20 years in whom urinary sedimentation had been performed at least twice between May 2011 and June 2012. The sperm group included patients in whom at least one urinary sediment test performed under a microscope had detected at least one sperm. We evaluated the associations between the presence of at least one sperm in urinary sediment and clinical parameters such as various diseases and the use of particular oral medicines.

Main Outcomes

In total, 1.6% (339/20,937) of urinary sediment samples contained at least one sperm. The sperm group consisted of 282 subjects (5.6%), and the no-sperm group included 4,723 subjects (94.3%).

Results

Multivariate analysis demonstrated that younger age (<65) (odds ratio [OR]: 1.71, 95% confidence interval [CI]: 1.32–2.21), the total number of examinations (≥4) (OR: 1.46, 95%CI: 1.11–1.92), diabetes (OR: 1.72, 95%CI: 1.31–2.25), a history of pelvic surgery for colon cancer (OR: 4.89, 95%CI: 2.38–10.02), alpha-1 blocker use (OR: 1.55, 95%CI: 1.16–2.08), a history of trans-urethral resection of the prostate (OR: 2.77, 95%CI: 1.46–5.13), and selective serotonin reuptake inhibitor use (OR: 2.12, 95%CI: 1.07–4.19) were independent predictors of the presence of at least one sperm in urinary sediment.

Conclusion

There is considerable overlap between the factors associated with the presence of at least one sperm in urinary sediment and those that are strongly associated with ejaculatory disorders.

Management of male neurologic patients with infertility

Many aspects of fertility rely on intact neurologic function and thus neurologic diseases can result in infertility. While research into general female fertility and alterations in male semen quality is limited, we have an abundance of knowledge regarding ejaculatory dysfunction following nerve injury. Normal ejaculation is the result of coordinated reflex activity involving both the sympathetic and somatic nervous systems. Nerve injury can result in retrograde ejaculation, and anejaculation. With retrograde ejaculation, the ejaculate is propelled into the bladder instead of out through the urethra. In mild cases this condition can be reversed by sympathomimetic medications and, in more severe cases, sperm cells can be extracted from the bladder following ejaculation. With anejaculation, the ejaculatory reflex is not activated by normal sexual stimulation. In such cases, the first choice of treatment is assisted ejaculation, preferably by penile vibratory stimulation. If vibratory stimulation is unsuccessful, then ejaculation can almost always be induced by electroejaculation. In cases where assisted ejaculation fails, sperm can be retrieved surgically from either the epididymis or from the testis. Once viable sperm cells have been obtained, these are used in assisted reproductive techniques, including intravaginal insemination, intrauterine insemination, and in vitro fertilization/intracytoplasmic sperm injection.

The effect of chronic bacterial prostatitis on semen quality in adult men: a meta-analysis of case-control studies

Chronic bacterial prostatitis (CBP) is caused by bacterial infection and maintains a condition of lower urinary tract infection. It may be a cause of male infertility. However, studies showed inconsistent results regarding the effect of CBP on several parameters of semen. Hence, we conducted a meta-analysis to examine the effect of CBP on basic semen parameters. A systematic review was conducted with Medline, PubMed, EMBASE, and two Chinese databases (CNKI and WANG FANG) to identify relevant studies that involved the effect of CBP on semen parameters up to July 2014. Both RevMan5.2 and STATA 12.0 software were used for the statistical analysis. Based on the inclusion and exclusion criteria, seven studies were included. The study illustrated that sperm vitality, sperm total motility, and the percentage of progressively motile sperm from CBP patients were significantly lower than controls (SMD(95%CI) −0.81[−1.14, −0.47], −1.00[−1.28, −0.73], −0.41 [−0.70, −0.12], P<0.05, respectively). However, CBP had no significant effect on semen volume, sperm concentration and the duration of semen liquefaction. In summary, our study revealed that there was a significant negative effect of CBP on sperm vitality, sperm total motility, and the percentage of progressively motile sperm. Additional, studies with larger number of subjects are needed.

The role of sympathetic and parasympathetic nerve systems on the smooth muscle of rat seminal vesicles - experimental results and speculation for physiological implication on ejaculation

Ejaculation is a process involving sympathetic and parasympathetic effects during different stages - emission and ejection. Some conditions of ejaculation dysfunction are associated with autonomic nerves. However, the exact effects of autonomic nerves on ejaculation are not well defined. Autonomic agonists induce different recorded trace patterns of seminal vesicular contraction. The different traces contain different components of phasic and tonic contraction, which may have physiological implications. In this study, we examined isolated rat seminal vesicle (SV) contraction by phenylephrine (PE), acetylcholine, and their respective antagonists and then speculated upon physiological roles of sympathetic and parasympathetic nerves on SV during ejaculation. We found that PE and Ach both achieved good contraction of rat SV. Compared to α1b for sympathetic and M1, M2 for parasympathetic receptors, α1a and M3 are the relatively dominant subtypes on rat SV. Adrenergic and cholinergic agonists cause different trace patterns of SV contraction. We speculated that the sympathetic effect is dominant during emission to squeeze seminal fluid out and that the parasympathetic effect is dominant during ejection to provide an anti-reflux effect on the ejaculatory duct.

Fertility preservation in patients undergoing gonadotoxic therapy or gonadectomy: a committee opinion

Patients preparing to undergo gonadotoxic medical therapy or radiation therapy or gonadectomy should be provided with prompt counseling regarding available options for fertility preservation. Fertility preservation can best be provided by comprehensive programs designed and equipped to confront the unique challenges facing these patients.

Approach to male infertility and induction of spermatogenesis

Male subfertility is common, and it causes significant duress to couples. Although the most common cause of male subfertility is idiopathic failure of spermatogenesis, a significant percentage of male subfertility is medically treatable. Compared to reproductive specialists, endocrinologists may see a population of men that have a higher prevalence of treatable causes of subfertility including sexual disorders, endocrinopathies, obesity, drugs, and ejaculatory dysfunction. Seminal fluid analysis is the most important diagnostic study, and at least 2 samples should be analyzed. All patients with sperm concentrations < 10 million/mL due to idiopathic spermatogenic defects should be referred for genetic counseling and karyotyping; most experts also recommend that these patients be tested for Y chromosomal microdeletions. For most men with low sperm concentrations due to gonadotropin deficiency, gonadotropin therapy effectively increases spermatogenesis. The endocrinologist must recognize when to use medical therapy to stimulate spermatogenesis and when to refer for consideration of assisted reproductive technology.

[Ejaculatory disorders except premature ejaculation, orgasmic disorders]

INTRODUCTION

Disorders of ejaculation and orgasm apart from premature ejaculation are pretty uncommon.

METHODS

Medical literature was reviewed and combined with expert opinion of the authors.

RESULTS

The semiology of these disorders is essential: aspermia, hypospermia, retrograde ejaculation, delayed or absent ejaculation with or without orgasm. Whether this is a lifelong or acquired condition, it is essential to assess the side-effects of medications i.e. psychotropic drugs, including antidepressant, neuroleptics, tramadol, alphablockers: tamsulosin and silodosin must always be surveyed.

CONCLUSION

The management is often difficult, especially with a parenthood perspective. The management of lifelong disorders must rely on psychosexual therapies.

PLCz functional haplotypes modulating promoter transcriptional activity are associated with semen quality traits in Chinese Holstein bulls

The sperm-specific phospholipase C zeta (PLCz) is a candidate sperm-borne oocyte-activating factor that triggers a characteristic series of physiological stimuli via cytoplasmic Ca²⁺ oscillations during fertilization. The molecular mechanisms involved in the regulation of PLCz gene expression remain largely unknown. To explore the genetic variations in the 5′-flanking region of the PLCz gene and their common haplotypes in Chinese Holstein bulls, as well as to determine whether these variations affect bovine semen quality traits and transcriptional activity, DNA samples were collected from Chinese Holstein bulls and sequenced for the identification of genetic variants in the 5′-flanking region of PLCz. Two genetic variants were identified, and their haplotypic profiles were constructed. The two novel genetic variations (g. −456 G>A and g. +65 T>C) were genotyped in 424 normal Chinese Holstein bulls. Bioinformatics analysis revealed that both loci are in transcription factor binding sites of the core promoter region. The association studies revealed that the two genetic variations and their haplotype combinations significantly affected semen quality traits. Using serially truncated constructs of the bovine PLCz promoters and the luciferase reporter, we found that a 726 bp (−641 nt to +112 nt) fragment constitutes the core promoter region. Furthermore, four haplotypes, H1H1 (GTGT), H2H2 (GCGC), H3H3 (ATAT), and H4H4 (ACAC), were significantly associated with semen quality traits and successfully transfected into MLTC-1 cell lines. The luciferase reporter assay showed that the different haplotypes exhibited distinct promoter activities. Maximal promoter activity was demonstrated by the H2H2 haplotypes, as compared with the other haplotypes. To the best of our knowledge, this study is the first report on genetic variants and their respective haplotypes in the 5′-flanking region of PLCz gene that can influence the semen quality of Chinese Holstein bulls as well as contribute to the transcriptional activity of the PLCz promoter.

Infertility in men with spinal cord injury: research and treatment

Spinal cord injury (SCI) occurs most often to young men. Following SCI, most men are infertile due to a combination of erectile dysfunction, ejaculatory dysfunction and semen abnormalities. Erectile dysfunction may be treated by the same therapies that are used in the general population. Similarly, the same treatments that are effective to assist conception in couples with non-SCI male factor patients are effective in assisting conception in SCI male-factor patients. The most apparent differences in male-factor symptoms between SCI and non-SCI patients are the high occurrences of anejaculation and atypical semen profiles in men with SCI. Methods available to assist ejaculation in men with SCI include penile vibratory stimulation and EEJ. Use of surgical sperm retrieval as the first line of treatment for anejaculation in men with SCI is controversial. Most men with SCI have a unique semen profile characterized by normal sperm concentration, but abnormally low sperm motility. Toxic substances in the semen contribute to this problem. Despite impaired sperm parameters, pregnancy outcomes using sperm from men with SCI are similar to pregnancy outcomes using sperm from non-SCI men. Future studies should focus on improving natural ejaculation and improving semen quality in these men.

Management of ejaculatory disorders in infertile men

Ejaculatory dysfunction is a highly prevalent clinical condition that may be classified along a continuum that ranges from premature ejaculation (PE), through retarded or delayed ejaculation (DE), to complete anejaculation (AE). Retrograde ejaculation (RE) represents a distinct entity in which ejaculate is expelled either partially or completely into the bladder. While DE and PE are significant sources of sexual dissatisfaction among men and their partners, patients with these disorders retain normal fertility in most cases. Conversely, men with AE and RE are unable to deliver sperm into the female genital tract and are therefore rendered subfertile. Therefore, in reviewing ejaculatory disorders as they relate to fertility, this paper will primarily focus on the diagnosis and management of AE and RE. Physiology, diagnostic strategies, pharmacological treatments, and procedural interventions relevant to AE and RE are discussed.

Male sexual dysfunction and infertility associated with neurological disorders

Normal sexual and reproductive functions depend largely on neurological mechanisms. Neurological defects in men can cause infertility through erectile dysfunction, ejaculatory dysfunction and semen abnormalities. Among the major conditions contributing to these symptoms are pelvic and retroperitoneal surgery, diabetes, congenital spinal abnormalities, multiple sclerosis and spinal cord injury. Erectile dysfunction can be managed by an increasingly invasive range of treatments including medications, injection therapy and the surgical insertion of a penile implant. Retrograde ejaculation is managed by medications to reverse the condition in mild cases and in bladder harvest of semen after ejaculation in more severe cases. Anejaculation might also be managed by medication in mild cases while assisted ejaculatory techniques including penile vibratory stimulation and electroejaculation are used in more severe cases. If these measures fail, surgical sperm retrieval can be attempted. Ejaculation with penile vibratory stimulation can be done by some spinal cord injured men and their partners at home, followed by in-home insemination if circumstances and sperm quality are adequate. The other options always require assisted reproductive techniques including intrauterine insemination or in vitro fertilization with or without intracytoplasmic sperm injection. The method of choice depends largely on the number of motile sperm in the ejaculate.

Ejaculatory dysfunction as a cause of infertility

Ejaculatory dysfunction (EjD), the most prevalent male sexual disorder, is clearly different from erectile dysfunction (ED). EjD is divided into 4 categories: premature ejaculation, delayed ejaculation, retrograde ejaculation and anejaculation. EjD-related infertility is one of the most serious problems in young patients. If sexual intercourse is achieved successfully without any ejaculate sexual partners/wives will not be able to conceive. Therefore, establishment of management of EjD as well as ED is increasingly crucial for couples wishing for a baby. The therapeutic approach of EjD-related infertility is based upon two scenarios: (1) if EjD alone is the reason for having no children, adequate treatment for EjD alone is required, or (2) if EjD is not the only reason and is combined with a worsening of semen quality, total management for male infertility (including EjD treatment) is needed. In this article, the background of EjD-related infertility is presented briefly, followed by a review of treatment modalities.

Steps in the investigation and management of low semen volume in the infertile man

An adequate semen volume of ejaculate fluid is required to transport sperm into the female reproductive tract and allow for fertilization of the oocyte. Thus, seminal fluid volume is an important part of the semen analysis done to investigate male infertility. In this article, we review the anatomy and physiology of ejaculation, the various etiologies of low-volume ejaculation (artifactual, structural, functional). We then present a comprehensive algorithm for the evaluation, diagnosis and treatment of the infertile man presenting with low semen volume.

Considerations for a better definition of male orgasmic disorder in DSM V

INTRODUCTION

All of the Diagnostic and Statistical Manual of Mental Disorders, 4th Ed., text revision (DSM-IV-TR) criteria for sexual disorders have been criticized on multiple grounds, including that the criteria lack precision, that the requirement of marked distress is inappropriate, and that the specification of etiological subtypes should be deleted.

AIM

The goal of this article is to review evidence relevant to diagnostic criteria for male orgasmic disorder published since 1990.

METHODS

Medline searches from 1990 forward were conducted using the terms male orgasmic disorder, anorgasmia, delayed ejaculation, retarded ejaculation, ejaculatory delay, and ejaculatory disorder. Early drafts of proposed alterations in diagnostic criteria were submitted to advisors.

MAIN OUTCOME MEASURE

Evidence reviewed was judged by current usage of terminology, evidence allowing precise definition of the syndrome, and evidence concerning separation of the syndrome from distress.

RESULTS

The literature search indicated minimal use of the term male orgasmic disorder and minimal knowledge concerning psychogenic ejaculatory problems.

CONCLUSIONS

It is recommended that the term male orgasmic disorder be replaced with the term delayed ejaculation. Duration and severity criteria are recommended. Since many ejaculatory problems are idiopathic, it is recommended that the etiological subtypes due to psychological or due to combined factors be eliminated.

Treatment of infertility in men with spinal cord injury

Most men with spinal cord injury (SCI) are infertile. Erectile dysfunction, ejaculatory dysfunction and semen abnormalities contribute to the problem. Treatments for erectile dysfunction include phosphodiesterase type 5 inhibitors, intracavernous injections of alprostadil, penile prostheses, and vacuum constriction devices. In anejaculatory patients who wish to father children, semen retrieval is necessary. Penile vibratory stimulation is recommended as the first line of treatment. Patients who fail penile vibratory stimulation can be referred for electroejaculation. If this approach is not possible, prostate massage is an alternative. Surgical sperm retrieval should be considered as a last resort when other methods fail. Most men with SCI have a unique semen profile characterized by normal sperm count but abnormally low sperm motility. Scientific investigations indicate that accessory gland dysfunction and abnormal semen constituents contribute to the problem. Despite abnormalities, sperm from men with SCI can successfully induce pregnancy. In selected couples, the simple method of intravaginal insemination is a viable option. Another option is intrauterine insemination. The efficacy of intrauterine insemination increases as the total motile sperm count inseminated increases. In vitro fertilization and intracytoplasmic sperm injection are options in cases of extremely low total motile sperm count. Reproductive outcomes for SCI male factor infertility are similar to outcomes for general male factor infertility.

Longevity of spermatozoa in the post-ejaculatory urine of fertile men

Many scientists of varying clinical backgrounds have described the phenomenon of spermaturia in animals, adolescents as well as fertile and infertile men. Nevertheless, research for an expert opinion on a law case in the field of forensic medicine revealed a lack of valid information about the longevity of spermatozoa in post-ejaculatory urine (PEU) of fertile men. Our goal was to measure the appearance of vivid sperm in PEU while considering the factor of time in order to predict a realistic interval, in which positive sperm findings might occur. Therefore ten healthy, young men donated their sperm for fertility analysis and a urine sample prior to and after ejaculation. The time intervals between ejaculation and the first micturition were preset ranging between 30 min and maximal 11h. Each ejaculate underwent a semen analysis. The pre- and post-ejaculatory urine samples were screened for the presence of viable and motile spermatozoa. Semen parameters were determined and related to the sperm findings in the precipitate of the urine samples. The amount, the viability and motility status of the detected spermatozoa were recorded after each preset time interval. The results showed that none of the 10 participants had sperm in their urine samples prior to ejaculation. The average sperm concentration was 50.1+/-25.8 million/ml. After a time span of 30 min 59.5% of the first fractions of PEU samples were sperm positive, after 2 and 4h still 70%, and after 5h sperm were no longer detected. The last motile spermatozoa could be found after 4.5h. It seems that remaining sperm in the urethra are washed out with the first micturition in the majority of fertile men, however, the conclusion as to whether sperm findings >5h after ejaculation are improbable needs to be confirmed by further investigations.
