High rate of detection of ultrasound signs of prostatitis in patients with HPV-DNA persistence on semen: role of ultrasound in HPV-related male accessory gland infection. J Endocrinol Invest 2019; 42:1459-1465. [PMID: 31165424 DOI: 10.1007/s40618-019-01069-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2019] [Accepted: 05/28/2019] [Indexed: 01/09/2023]
Abstract
BACKGROUND Papillomavirus (HPV) often occurs in the semen of patients with male accessory gland infection (MAGI). Ultrasound (US) evaluation has been suggested as a promising diagnostic tool for patients with HPV-related MAGI. No data on the spontaneous clearance of HPV-DNA have been reported so far in HPV-related MAGI. PURPOSE The primary aim of the study was to assess the percentage of early HPV-DNA spontaneous clearance in patients with prostatitis. The secondary aim was to evaluate the frequency of spontaneous clearance of HPV-DNA among patients with prostatitis associated with the presence or absence of US abnormalities. METHODS Patients with inflammatory MAGI and at least one suspicious criterion for HPV infection underwent semen HPV-DNA detection and prostate US. The presence of HPV-DNA was further investigated after a 6-month-long follow-up. MAIN RESULTS Eighty patients satisfied the inclusion criteria and were recruited in the study. 69% of patients (55/80) showed HPV-DNA persistence in the semen. Among them, 82% (45/55) was positive for US signs of prostatitis, while they occurred only in 12% (3/25) of those patients with no sign of HPV-DNA persistence (p < 0.001). All patients with persistent high-risk HPV genotype (n = 30) showed at least two US signs of prostatitis. In 73% of patients (22/30), E6 and E7 mRNAs were detected. CONCLUSION US signs of prostatitis more frequently occurred in patients with evidence of HPV-DNA persistence on semen, especially in those with high-risk genotypes. This highlights the importance of US in the framework of HPV-related MAGI.

Abstract
BACKGROUND Oxidative stress (OS) is one of the most prevalent causes of sperm damage, through the toxic effects of endogenously generated hydrogen peroxide, superoxide anion, and hydroxyl radicals. Peripheral leukocytes represent a feasible model for studying the pathophysiology of OS-mediated homeostasis, which can be responsible for cell dysfunction and cell injury. OBJECTIVE To evaluate the redox status in patients with non-obstructive azoospermia (NOA), establishing the potential role exerted by reactive oxygen species (ROS) in the genesis of testicular secretory injury. MATERIAL AND METHODS From May 2018 to March 2019, 39 patients were enrolled in this prospective single-center cohort study and divided into two groups. Group 1 included 19 patients with NOA, and Group 2 included 20 normozoospermic men, partners of women with infertility tubal factor. All patients underwent serum blood tests. NOA underwent testicular sperm extraction (TeSE). ROS production (in lymphocytes, monocytes, and granulocytes) was assessed by fluorescence-activated cell sorting (FACS) analysis. Plasma oxidative stress was evaluated by lipid peroxidation markers (MDA) and total antioxidant capacity (TAC) both assessed by fluorometric techniques. RESULTS Mean lymphocyte ROS production resulted 967.0 ± 224.5 vs 728.0 ± 98.0 (NOA vs Controls, P < .001), monocyte ROS resulted 2102.5 ± 517.5 vs 1253 ± 171 (P < .001), and granulocyte ROS were 2366.5 ± 595.4 vs 1751.0 ± 213.0 (P < .001). Significant increases plasma lipid peroxidation markers were found in NOA patients compared with controls (2.7 ± 0.8 vs 0.37 ± 0.2 nmol/mL, P < .001). Significant decreased TAC was evident in NOA compared with controls (13.4 ± 3.9 vs 3.0 ± 0.2 µmol/mL Trolox equivalents, P < .001). No significant differences were found in blood leukocyte subpopulations ROS production, plasma lipid peroxidation, and TAC comparing groups (positive vs negative sperm retrieval, P > .05). CONCLUSION ROS production can be directly related to disorders of spermatogenesis, leading to severe conditions of male infertility, including azoospermia.

Abstract
Background The exact mechanism of varicocele-related infertility is still elusive, therefore, the current challenges for its management lie in determining which patients stand to benefit most from surgical correction. The authors aimed to assess the clinical factors affecting semen improvement after left microsurgical subinguinal varicocelectomy (MSV) in relation to patient age, ultrasound varicocele grading (USVG), and presence of a right subclinical varicocele (RSV). Methods From 2010 to 2017 a total of 228 infertile patients underwent left MSV for clinical varicocele. Descriptive statistics were used to describe the cohort and verify the surgical benefit in terms of semen improvement, in addition, subsets of patients were selected according to clinical covariates. Logistic regression modeling was applied to evaluate the presence of RSV, operative time, age, and USVG as explanatory variables. Results Sperm concentration (SC), progressive sperm motility (PSM), and normal sperm morphology (NSM) increased significantly after surgery (p = 0.002; p = 0.011; p = 0.024; respectively). Mean SC improved after MSV in ⩾35 year-old patients and the grade 3 USVG group (p = 0.01; p = 0.02; respectively). Logistic regression modeling showed a that the probability of SC improvement was 76% lower in subjects presenting RSV (p = 0.011). In addition, patients with a grade 3 USVG presented a three-times greater probability of SC improvement compared with patients with a lower USVG (p = 0.035). In addition, older patients showed a greater probability of SC improvement after MSV (p = 0.041). Conclusions MSV is an effective varicocele-related infertility treatment that should also be offered to older patients. In addition, patients with a higher USVG benefit from surgery. In infertile men with an RSV in association with a left clinical disease, a bilateral varicocele repair should be considered.

Abstract
Introduction: Klinefelter syndrome (KS) represents the most common chromosomal abnormality in the general population, and one of the most common genetic etiologies of nonobstructive azoospermia (NOA) and in severe oligospermia. Once considered untreatable, men with KS and NOA now have a variety of treatment options to obtain paternity.Areas covered: The cornerstone of treatment for both KS and NOA patients remains the surgical retrieval of viable sperm, which can be used for intracytoplasmic sperm injection to obtain pregnancy. Although the field has advanced significantly since the early 1990s, approximately half of men with KS will ultimately fail fertility treatments. Presented is a critical review of the available evidence that has attempted to identify predictive factors for successful sperm recovery. To optimize surgical success, a variety of treatment modalities have also been suggested and evaluated, including hormonal manipulation and timing of retrieval.Expert opinion: Individuals with KS have a relatively good prognosis for sperm recovery compared to other men with idiopathic NOA. Surgical success is heavily dependent upon surgical technique and the experience of the andrology/embryology team tasked with the identification and use of testicular sperm.

Abstract
Microsurgical longitudinal intussusception vasoepididymostomy (LIVE) has been widely used to treat epididymal obstructive azoospermia since 2004. Although the deferential vasculature plays an important role in supplying blood to the testis and epididymis, little attention has been paid to the potential benefits of sparing the deferential vessels during the anastomosis in LIVE. This study aimed to evaluate the efficacy and safety of deferential vessel-sparing LIVE in humans. From December 2013 to December 2015, 69 azoospermic men with epididymal obstruction due to a genital infection, trauma, or idiopathic factors underwent deferential vessel-sparing LIVE in the First Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China. The outcomes of these patients were analyzed retrospectively. The mean age was 31.1 years for men and 28.3 years for their partners. Fifty-nine (85.5%, 59/69) men were followed up after surgery for approximately 16 months. Patency was noted and confirmed by semen analysis (>10 000 sperm/ml) in 83.1% (49/59) of men. The natural pregnancy rate was 40.7% (24/59) by the end of the study, with 87.5% (21/24) of these natural pregnancies achieved within 12 months after surgery. No severe adverse events or complications were observed. In this study, we present a novel technique for sparing the deferential vessels during LIVE. The preliminary outcomes show this technique to be safe with favorable patency and pregnancy rates.

Abstract
PURPOSE Varicocele repair (VR) is proposed to improve fertility in subfertile couples with a poor semen quality. We explored whether the disappearance of a left continuous spermatic venous reflux (SVR) at scrotal colour-Doppler ultrasound (CDUS), an objective evidence for a VR, is predictive for improved fertility outcome in subfertile couples. METHODS VR was performed by left internal spermatic vein sclero-embolisation in 88 males seeking a consultation for subfertility. Semen analysis and scrotal CDUS were evaluated before and 6 months after VR. Serum levels of FSH and total testosterone (TT) were obtained at baseline. Telephone interview was used to obtain information about fertility outcome. Significant predictors of pregnancy and live births, selected by univariate analyses, were included into multiple logistic regression models to assess independent associations. RESULTS At the adjusted model, independent significant predictors of pregnancy after VR were a disappeared SVR at CDUS (OR = 5.5, 97.5% CI 2.01-15.4; p = 0.0009) and an improved sperm total motile count (TMC) (OR = 5.5, 97.5% CI 1.4-27.9; p = 0.02). Even live births were independently associated with both disappeared left SVR at CDUS (OR = 4.3, 97.5% CI = 1.6-11.8; p = 0.003) and improved TMC after VR (OR = 4.8, 97.5% CI 1.3-24.2; p = 0.02). CONCLUSION The still controversial effect of varicocele repair on fertility in subfertile couples may reside on the undefined objective methods to document a successful VR and its effect on couple fertility. The disappearance of a continuous left SVR at CDUS after VR was the objective best predictor for subsequent improved fertility in subfertile couples.

Abstract
We summarized our experience in transurethral seminal vesiculoscopy (TSV) for recurrent hemospermia by introducing surgical techniques, intraoperative findings, and treatment outcomes. TSV was performed in 419 patients with an initial diagnosis of persistent hemospermia at Shanghai Changhai Hospital (Shanghai, China) from May 2007 to November 2015. TSV was successfully performed in 381 cases (90.9%). Hemospermia was alleviated or disappeared in 324 (85.0%) patients by 3 months after surgery. Common intraoperative manifestations were bleeding, obstruction or stenosis, mucosal lesions, and calculus. Endoscopic presentation of the ejaculatory duct orifice and the verumontanum was categorized into four types, including 8 (1.9%), 32 (7.6%), 341 (81.4%), and 38 (9.1%) cases in Types A, B, C, and D, respectively. TSV is an effective and safe procedure in the management of seminal tract disorders. This study may help other surgeons to become familiar with and improve this procedure. However, further multicentric clinical trials are warranted to validate these findings.

High prevalence of urogenital infection/inflammation in patients with azoospermia does not impede surgical sperm retrieval. Andrologia 2019; 51:e13401. [PMID: 31456226 PMCID: PMC7147116 DOI: 10.1111/and.13401] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 07/21/2019] [Accepted: 07/22/2019] [Indexed: 01/12/2023] Open
Abstract
Considering infection/inflammation to be an important risk factor in male infertility, the aim of this study was to make a comprehensive evaluation of the prevalence of urogenital tract infection/inflammation and its potential impact on sperm retrieval in azoospermic patients. In this prospective study, 71 patients with azoospermia were subjected to an extensive andrological workup including comprehensive microbiological diagnostics (2-glass test, semen, testicular swab and testicular tissue analysis) and testicular biopsy/testicular sperm extraction (TESE). Medical history suggested urogenital tract infection/inflammation in 7% of patients, 11% harboured STIs, 14% showed significant bacteriospermia, 15% had seminal inflammation, 17% fulfilled the MAGI definition, and 27% had relevant pathogens. At the testicular level, 1 patient had a swab positive for bacteria, no viruses were detected, tissue specimens never indicated pathogens, whereas histopathology revealed focal immune cell infiltrates in 23% of samples. Testicular sperm retrieval rate was 100% in obstructive and 46% in nonobstructive azoospermia. None of the infection/inflammation-related variables was associated with the success of sperm retrieval or inflammatory lesions in the testis. The high prevalence of urogenital infection/inflammation among azoospermic men underpins their role as significant aetiologic factors in male infertility. However, this observation does not refer to the chances of sperm retrieval at the time of surgery/TESE.

Abstract
Seminal duct obstruction may result in obstructive azoospermia (OA) and severe oligoasthenoteratozoospermia (OAT) (<0.5 million/mL) (Nordhoff et al., 2015). Cases of partial OA and OAT can be treated effectively by microsurgical anastomosis (Goldstein and Kim, 2013) to obtain successful surgical reversal. However, microsurgical vasovasostomy (VV) (Dickey et al., 2015) and vasoepididymostomy (VE) (Peng et al., 2017) are not suitable for patients with atypical OA and poor epididymis conditions or unpredictable obstruction of the distal vas deferens. For those patients, cross anastomosis may be applied instead of routine VE or VV. A single-center, retrospective, comparison study was conducted, which assessed the usefulness of the cross VV (CVV) in the scrotum for indication and efficacy. A total of 77 cases with OA or OAT were included, and 20 cases implemented cross anastomosis, including unilateral CVV (UCVV) in 4 cases, unilateral VE plus CVV (UVE+CVV) in 11 cases, and unilateral VV-based CVV (UVV+CVV) in 5 cases. The other 57 cases received no cross-matching anastomosis. The patency and natural pregnancy rates in one year were 75.0% and 50.0%, respectively, in the UCVV group; 54.5% and 27.3%, respectively, in the UVE+CVV group; and 60.0% and 40.0%, respectively, in the UVV+CVV group. The CVV in the scrotum in the selected patients with OA and severe OAT could yield good results. We regard the CVV in the scrotum as an efficacious operation with a lower risk of injury in cases of atypical OA.

Abstract
STUDY QUESTION Is the anogenital distance (AGD) correlated to anthropometric, genital and sperm parameters in young adult men? SUMMARY ANSWER We observed that reduced AGD is strongly associated with altered semen parameters and reduced testicular volume. WHAT IS KNOWN ALREADY Abnormalities in the foetal development of the testis have been suggested as causative of common male reproductive disorders, such as cryptorchidism, hypospadias, reduced semen quality and testicular germ cell tumour, collectively defined as 'testicular dysgenesis syndrome'. In human epidemiological studies, alterations in AGD have been frequently associated with clinically relevant outcomes of reproductive health, suggesting AGD as a marker of foetal testicular development. STUDY DESIGN, SIZE, DURATION This study was performed within the annual screening protocol to evaluate male reproductive health in the high schools of Padua and surroundings (Veneto Region, the North-East of Italy). Here we report the findings of 794 subjects who completed the study protocol between October 2016 and May 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS We evaluated 794 students aged 18-19 years recording the following parameters: height, weight, BMI, waist circumference, arm span, pubis-to-floor and crown-to-pubis length, penile length and circumference, testicular volumes, semen parameters and AGD (measured from the posterior base of the scrotum to the centre of the anus). MAIN RESULTS AND THE ROLE OF CHANCE Of the subjects, 49% had an abnormal arm span-height difference (>3 cm) and 63.4% had an altered ratio of crown-to-pubis/pubis-to-floor length (≤0.92). The rate of subjects with reduced testicular volume was 23%. Median sperm concentration was 51.0× 106/ml and total sperm count was 122.5 × 106. AGD showed a direct positive relation with testicular volume and penile length and circumference (R = 0.265, 0.176 and 0.095, respectively, all P < 0.05). No significant relation was observed between AGD and anthropometric parameters. Sperm concentration, total sperm count, progressive motility and normal morphology showed a significant and positive correlation with AGD (R = 0.205, 0.210, 0.216 and 0.117, respectively, all P < 0.05). LIMITATIONS, REASONS FOR CAUTION Our cohort of young adults is not representative of the general population. Hormonal evaluation was missing. WIDER IMPLICATIONS OF THE FINDINGS Our findings show that AGD is associated with testicular volumes, penile measures and seminal parameters in young adult men. Because AGD is hormonally determined during foetal life, the reported high incidence of reduced semen quality and reduced testicular volume could be related to a reduced androgenic exposure in utero. AGD could represent a simple and useful method to evaluate testicular and penile development in adult men. STUDY FUNDING/COMPETING INTEREST(S) The authors have no potential conflict of interest to declare. No external funding was obtained for this study. TRIAL REGISTRATION NUMBER N/A.

Abstract
BACKGROUND Although the pathogenic role of metabolically complicated obesity (MCO) in erectile dysfunction (ED), major adverse cardiovascular events (MACE), and male infertility has been widely studied, that of metabolically healthy obesity (MHO) has been poorly investigated. AIM To assess the role of MHO in the pathogenesis of ED, prediction of MACE, and male reproductive health. METHODS A consecutive series of 4,945 men (mean age, 50.5 ± 13.5 years) with sexual dysfunction (SD) (cohort 1) and 231 male partners of infertile couples (mean age, 37.9 ± 9.1 years; cohort 2) were studied. A subset of men with SD (n = 1,687) was longitudinally investigated to evaluate MACE. All patients underwent clinical, biochemical, erectile function, and flaccid penile color Doppler ultrasound (PCDU) assessment. Infertile men also underwent scrotal and transrectal ultrasound; semen analysis, including interleukin (IL-) 8; and prostatitis-like symptom assessment. MHO was defined as body mass index >30 kg/m2 with high-density lipoprotein cholesterol level >40 mg/dL and absence of diabetes or hypertension. The rest of the obesity sample was defined as MCO. MHO or MCO were compared with the rest of the sample, defined as normal weight (NW) individuals. OUTCOMES Clinical, biochemical, erectile, and PCDU assessment in MHO, MCO and NW men in both cohorts; longitudinal MACE incidence assessment in cohort 1. RESULTS In cohort 1, 816 men (16.5%) were obese, 181 (3.7%) were MHO, and 635 (12.8%) were MCO. In cohort 2, 68 men (28.4%) were obese, 19 (8.2%) were MHO, and 49 (21.2%) were MCO. After adjusting for confounders, in both samples, the men with MHO and MCO had lower total testosterone levels and worse PCDU parameters compared with the NW men. However, only MCO men had worse erectile function compared with NW men. In the longitudinal study, both MHO and MCO men independently had a higher incidence of MACE compared with NW men (P < .05 for both). In cohort 2, MHO and MCO men had a larger prostate volume, and MCO men also had higher ultrasound and biochemical (IL-8) features of prostatic inflammation compared with NW men, but no differences in prostatitis-like symptoms or seminal parameters. CLINICAL IMPLICATIONS MHO men should be considered at high cardiovascular risk like MCO men and followed-up for erectile dysfunction and prostate abnormalities overtime. STRENGTHS & LIMITATIONS The study simultaneously examined several endpoints with validated instruments within 2 different male populations, 1 with SD and 1 with infertility. As for limitations, there is no consensus in the scientific community regarding the definition of MHO, and the results are derived from patients with SD or infertility, which could have different characteristics than the general male population. CONCLUSION MHO is associated with subclinical ED, increased cardiovascular risk, and prostate enlargement. Lotti F, Rastrelli G, Maseroli E, et al.

Abstract
To investigate the sonographic findings of the vas deferens in male genital tuberculosis.The ultrasonographic findings of the vas deferens of 19 cases of genital tuberculosis were retrospectively analyzed.According to the pathological and ultrasound findings, the ultrasonographic appearances of the vas deferens tuberculosis could be divided into 4 groups, 1 of normal sonograms, 3 of abnormal sonograms. The abnormal ultrasonographic appearances of the vas deferens tuberculosis were considered 3 categories as follows: diffusely thickening of vas deferens, nodular thickening of vas deferens, and space-occupying lesions adjacent to the vas deferens.The ultrasound manifestations of vas deferens in tuberculosis of the male genital system have certain characteristics. Combination of clinical manifestations, history of tuberculosis, experimental antituberculosis treatment, and ultrasound examination of vas deferens can suggest tuberculosis of vas deferens. Furthermore, it can provide objective basis for the comprehensive and noninvasive evaluation of the impact of genital tuberculosis on the reproductive ability for further treatments.

Abstract
Objective: To evaluate the effect of nontense vaginal hydrocele in male partner with oligoasthenospermia on the success rates of the intracytoplasmic sperm injection (ICSI). Patients and Methods: Enrolled patients (n = 60) were divided into two groups: Group I who have oligoasthenospermia with nontense vaginal hydrocele (study group) and Group II who have oligoasthenospermia with no hydrocele group (control group). The primary outcomes included the fertilization and pregnancy rates whereas the secondary outcomes included any complications occurred. Results: There were no differences in demographic characteristics between both groups. Semen parameters were poorer in the hydrocele group than in the nonhydrocele group regarding count and motility (P < 0.001). The volume of testis was reduced significantly in the hydrocele group (P < 0.001). The results of ICSI regarding fertilization rate, number and quality of developed embryos, and pregnancy rates are not statistically different between both groups. Conclusion: Hydrocele affects both sperm count and motility, but it has no effects on ICSI outcomes. Clinical pregnancy rate was comparable in patients with or without hydrocele. Hence, the surgical management of hydrocele before ICSI is not recommended.

Abstract
Sperm DNA fragmentation (sDF) has emerged as a valuable tool for evaluating male fertility, yet the relationship between DNA fragmentation in the male gamete and idiopathic recurrent pregnancy loss (RPL) remains a topic of ongoing debate. Hence, a meta-analysis was conducted of 12 prospective and 2 retrospective studies involving 530 men with a history of RPL who underwent sDF testing compared with 639 fertile control participants. The main outcome measures were sDF measured by comet assay, TdT (terminal deoxynucleotidyl transferase)-mediated dUDP nick-end labelling (TUNEL), sperm chromatin dispersion (SCD) or sperm chromatin structure assay. Overall, couples with a history of idiopathic RPL demonstrated higher levels of sDF than fertile couples (average mean difference 11.98, P < 0.001). Subgroup analysis demonstrated a similar average mean difference between the RPL and control groups using SCD compared with TUNEL, while mean paternal age and mean sperm motility in the RPL groups tested by meta-regression demonstrated no significant effect on the mean differences in sDF (P > 0.10). These results support the diagnostic value of sDF over standard semen analysis, as well as a possible paternally derived genetic origin of unexplained RPL. Further prospective studies are required to further assess the predictive utility of sDF for assessing couples with unexplained RPL.

Abstract
Objective To assess whether the “testicular pool” could be used for histological analysis and whether it gave more accurate information than the standard testicular biopsy. Methods Between January 2017 and March 2018, this single-center prospective study included 60 azoospermic men undergoing conventional bilateral testicular sperm extraction. Six samples were excised from each testicle and transferred to an embryologist. One additional biopsy was randomly taken from each testis for a histological analysis. After processing, the testicular pool was also sent for a histological analysis, which showed normal spermatogenesis (NS), hypospermatogenesis (HYPO), maturation arrest (MA), Sertoli cell-only syndrome (SCOS), and tubular atrophy (TA). Results Twenty of the 60 patients (33.3%) had obstructive azoospermia (OA), while the remaining 40 (66.6%) had nonobstructive azoospermia. Their mean age was 40.5 years. All patients with OA had previously undergone unsuccessful testicular fine-needle aspiration. Successful sperm retrieval (SSR) occurred in 93.3% of patients. Histological analysis of the testicular biopsy revealed NS in 12 patients (20%), HYPO and TA in 28 patients (46.6%), MA in eight patients (13.3%), and SCOS in 12 patients (20%). The testicular pool analysis showed NS in 12 patients (20%), HYPO and TA in 44 patients (73.3%), MA in four patients (6.6%), and SCOS in no patients. In four patients with MA (6.6% of the total sample) and 12 patients with SCOS (20% of the total sample) according to the standard testicular biopsy, the embryologist found SSR with cryopreservation. Overall, in 44 patients (73.3%), the testicular pool analysis confirmed the histological findings of the standard testicular biopsy. In the 16 cases (26.6%) with a discrepancy between the single-biopsy histological findings and SSR, the testicular pool analysis confirmed the embryological data on SSR. Conclusion The testicular pool proved to be easily analyzable, practical, manageable, and more accurate for predicting sperm retrieval than standard testicular biopsy.

Azoospermia in male dromedary: Clinical findings, testicular biopsy, serum follicle stimulating hormone and seminal biomarkers. Anim Reprod Sci 2018; 199:24-29. [PMID: 30340855 DOI: 10.1016/j.anireprosci.2018.10.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2018] [Revised: 09/29/2018] [Accepted: 10/09/2018] [Indexed: 01/28/2023]
Abstract
Azoospermia is not an uncommon infertility problem in the male dromedary (Camelus dromedarius). Azoospermia was investigated via clinical findings, testicular biopsy as well as the evaluation of follicle stimulating hormone (FSH), concentration of camel testis protein (TEX101) and camel epididymis-specific extracellular matrix protein (ECM1) in seminal fluids. Azoospermic male camels (AZOO group, n = 28) that had been detected to be infertile as a result of lack of resulting pregnancies after repeated mating's for at least one season were included in this study. Clinical examination, semen analysis and testicular biopsy sampling were conducted for each individual animal. Blood samples were collected from the AZOO and from reference fertile males (FERT group, n = 8) for the assay of FSH hormone and semen biomarkers (TEX101 and ECM1). There were bilaterally normal-sized testes in 42.8%, bilaterally small-sized testes in 35.7%, bilaterally large-sized testes in 7.1%, no testicles in 7.1% and only one testicle in 7.1% of azoospermic animals. Sertoli cell-only syndrome (SCO) and maturation arrest were observed in 78.6% and 21.4% of the animals, respectively. There were greater concentrations of FSH in the AZOO group compared with the FERT group (P = 0.01). In conclusion, azoospermia in dromedary camels is mainly associated with spermatogenic defects and greater serum FSH concentrations. Seminal biomarkers, therefore, might be feasible indicators for identifying azoospermia in the male dromedary camels and the condition of non-obstructive azoospermia was seemingly prevalent in the male dromedary camels in the present study.

Abstract
OBJECTIVE The aim of this prospective study was to compare scrotal ultrasonographic findings in obese and normal weight infertile men and correlate these findings with semen parameters and hormonal profile. MATERIAL AND METHODS A total of 188 men presented for infertility evaluation were included in this study. They were divided according to body mass indices into obese (n=96) and normal weight infertile patients (n=92). Basic infertility evaluation, semen analysis and scrotal duplex ultrasound examination in addition to measurement of serum levels of follicular stimulating hormone, testosterone and estradiol were done for all cases. The ratio between testicular size measured by scrotal ultrasound and body mass index were calculated. RESULTS Any significant differences were not observed in semen parameters, serum levels of follicular stimulating hormone and testosterone between obese and normal weight infertile men (p>0.05). Serum estradiol level was significantly higher in obese than normal weight infertile men (p<0.001). There is significant increase in subclinical varicocele, hydrocele and testicular microlithiasis detected by scrotal ultrasound in obese infertile men than nonobese patients (p<0.05). Despite having comparable testicular size detected on scrotal ultrasound, infertile obese men had significantly lower total testicular volume to body mass index ratio and this ratio correlated positively with semen volume, sperm concentration, total sperm count and serum testosterone but negatively with serum follicular stimulating hormone and estradiol levels. CONCLUSION We therefore conclude that the incidence of subclinical varicocele, hydrocele and testicular microlithiasis was higher in obese infertile patients and the ratio between testicular volume assessed by scrotal ultrasound and body mass index may be a new parameter that correlates with subfertility status in these men.

Abstract
Background Meiotic homologous recombination (HR) plays an essential role in gametogenesis. In most eukaryotes, meiotic HR is mediated by two recombinase systems: ubiquitous RAD51 and meiosis-specific DMC1. In the RAD51-mediated HR system, RAD51 and five RAD51 paralogues are essential for normal RAD51 function, but the role of RAD51 in human meiosis is unclear. The knockout of Rad51 or any Rad51 paralogue in mice exhibits embryonic lethality. We investigated a family with meiotic arrest, azoospermia and infertility but without other abnormalities. Methods Homozygosity mapping and whole-exome sequencing were performed in a consanguineous family. An animal model carrying a related mutation was created by using a CRISPR/Cas9 system. Results We identified a 1 bp homozygous substitution (c.41T>C/p.Leu14Pro) on a RAD51 paralogue, namely, XRCC2, in the consanguineous family. We did not detect any XRCC2 recessive mutation in a cohort of 127 males with non-obstructive-azoospermia. Knockin mice with Xrcc2-c.T41C/p.Leu14Pro mutation were generated successfully by the CRISPR/Cas9 method. The homozygotes survived and exhibited meiotic arrest, azoospermia, premature ovarian failure and infertility. Conclusion A XRCC2 recessive mutation causing meiotic arrest and infertility in humans was duplicated with knockin mice. Our results revealed a new Mendelian hereditary entity and provided an experimental model of RAD51-HR gene defect in mammalian meiosis.

Abstract
Chronic epididymitis and varicocele are frequently observed genital disorders in men consulting for couple infertility, but their impact on semen characteristics at the time of infertility consultation is still a matter of debate. We investigated 652 male partners of couples who had their first infertility consultation between 1999 and 2015 in Argentina. Men with chronic epididymitis (n = 253), Grade III varicocele (n = 106), and both conditions (n = 125) were compared with a control group (n = 168) composed of men without these disorders or any other recognized causes of male infertility. We showed that men who presented isolated chronic epididymitis were more likely to have high percentages of low sperm motility and abnormal sperm morphology as well as a high number of white blood cells. Men with isolated Grade III varicocele had low sperm production and motility and an increased percentage of abnormal sperm morphology. Finally, men who simultaneously presented chronic epididymitis with Grade III varicocele had a low sperm motility and increased percentage of abnormal sperm morphology as well as a high number of white blood cells. Physical examination of the genital organs may identify common disorders, potentially involved as causal factors of patient's infertility. These disorders are associated with specific seminal profiles that should help in identifying the best treatment from the available therapeutic options, effectiveness, safety, and allowing as much as possible natural conception.

Abstract
Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) have been proposed to play a pivotal role in male infertility due to their anabolic effects. The aim of this study was to investigate possible associations between seminal plasma levels of GH and IGF-1 and sperm parameters. Fifty men participated in this study. Semen analysis was performed, while cell-free seminal plasma was collected following sperm centrifugation. Seminal plasma concentrations of IGF-1 and GH were determined by enzyme-linked immunosorbent assay (ELISA). Due to the presence of asthenozoospermia in all participants who presented with abnormal sperm parameters, the participants were further subdivided into normal (group A), asthenozoospermic (group B) and asthenozoospermic plus at least one additional abnormal parameter (group C). A marginally nonsignificant statistical difference (p = 0.063) was revealed between the GH levels corresponding to the asthenozoospermic and the normal group with the latter presenting with higher GH levels. A statistically significant positive correlation (p < 0.05) was noted between levels of GH and IGF-1 in group C. The above relationship has also been observed in men with low sperm concentration, vitality, volume and abnormal morphology. These novel findings require further investigation in order for the biological significance of those associations to be clarified.

Abstract
Myriad biological factors have been proposed to explain premature ejaculation (PE). However, data correlating PE with seminal vesicles (SVs) are sparse. The study aimed to evaluate the relationship between the size of SV and PE. The cross-sectional study included 44 outpatients with PE and 44 volunteers without PE, and the size of SV was compared. Self-estimated intravaginal ejaculatory latency time, the Premature Ejaculation Diagnostic Tool (PEDT), the International Index of Erectile Function-15, and the National Institutes of Health-Chronic Prostatitis Symptom Index were used for assessment of symptoms. Compared to the control group, the PE group had significantly higher mean anterior-posterior diameter (APD) of SV (P < 0.001). The optimal mean APD of SV cutoff level was 9.25 mm for PE. In the PE group, PEDT was also higher with a mean APD of SV ≥9.25 mm compared with mean APD of SV <9.25 mm. PEDT was significantly correlated with the mean APD of SV (r = 0.326, P = 0.031). The seminal plasma proteins were compared between six PE and six matched control cases by mass spectrometry and it was shown that 102 proteins were at least 1.5-fold up- or down-regulated. Among them, GGT1, LAMC1, and APP were significantly higher in the PE group. These results indicated that men with a larger mean APD of SV might have a higher PEDT score. Transrectal ultrasound of SV should be considered in the evaluation of patients with premature ejaculation. SV might be a potential target for the treatment of patients with PE and ultrasound change in SV.

Abstract
INTRODUCTION Male infertility affects about 7% of the general male population, and it is a multifactorial, polygenic pathological condition. Known genetic factors, accounting for about 20-25% of male factor infertility, are present in each etiological category: i) hypothalamic-pituitary axis dysfunction; ii) quantitative and qualitative alterations of spermatogenesis; iii) ductal obstruction/dysfunction. Areas covered: All routinely available genetic tests are described. Indication for testing for chromosomal anomalies and Y chromosome microdeletions is based on sperm count (severe oligozoospermia/azoospermia). Mutation screening in candidate genes is indicated in specific semen/testis phenotypes. In about 40% of infertile patients, the aetiology remains unknown ('idiopathic cases') and whole exome sequencing may reveal novel genetic causes. Expert commentary: Genetic testing is essential for its relevance in clinical decision-making. For instance, it helps to avoid unnecessary surgical or medical treatments and it may provide prediction for testicular sperm retrieval. The highest frequency of genetic anomalies is observed in severe spermatogenic impairment, which can be treated with in vitro fertilization (IVF). Given the risk of transmitting genetic disorders to the future offspring through IVF, the diagnosis of known and the discovery of novel genetic factors in idiopathic infertility is of outmost clinical importance.

Abstract
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.

Abstract
We investigated whether DNA fragmentation in two cytometric sperm populations (PIdimmer and PIbrighter) with different biological characteristics and clinical relevance is related to clinical and color-Doppler ultrasound (CDUS) parameters of the male genital tract. One hundred and sixty males of infertile couples without genetic abnormalities were evaluated for clinical, scrotal, and transrectal CDUS characteristics, presence of prostatitis-like symptoms (with the National Institutes of Health-Chronic Prostatitis Symptom Index) and sperm DNA fragmentation (sDF) in PIdimmer and PIbrighter populations (using TUNEL/PI method coupled with flow cytometry). Data were adjusted for age (Model 1) along with waistline, testosterone levels, smoking habit, and sexual abstinence (Model 2). According to the statistical Model 2, PIdimmer sDF was associated with testicular abnormalities, including lower clinical and ultrasound volume (r = -0.21 and r = -0.20, respectively; P < 0.05), higher FSH levels (r = 0.34, P < 0.0001) and occurrence of testicular inhomogeneity (P < 0.05) and hypoechogenicity (P < 0.05). PIbrighter sDF was associated with prostate-related symptoms and abnormal signs, including higher NIH-CPSI total and subdomain scores, a higher prevalence of prostatitis-like symptoms and of CDUS alterations such as macro-calcifications, severe echo-texture inhomogeneity, hyperemia (all P < 0.05), and higher arterial peak systolic velocity (r = 0.25, P < 0.05). Our results suggest that DNA fragmentation in PIdimmer sperm, which is related to poor semen quality, mainly originates in the testicles, likely due to apoptosis. Conversely, DNA fragmentation in PIbrighter sperm appears to mainly originate during or after transit through the prostate, increasing with the presence of an inflammatory status of the organ. These results could lead to new perspectives for the identification of therapeutic targets to reduce sDF.

Abstract
BACKGROUND The role of real-time elastography (RTE)-targeted biopsy in the detection and diagnosis of prostate cancer (PCa) remains controversial. METHODS We searched Medline, Embase, and Cochrane Library from inception to July 31, 2017 and used the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool to assess the quality of the identified studies. We applied the relative sensitivity value to assess the diagnostic accuracy of RTE-targeted biopsy using the 10-core systematic biopsy as the reference standard. RESULTS Seven studies comprising 5 cohorts and 2 randomized controlled trials (RCTs) were included. Of the 5 cohorts that encompassed 698 participants, we found that RTE-targeted biopsy did not outperform systematic biopsy in either overall PCa detection (69.5% vs 80.5%, relative sensitivity 0.92, 95% CI 0.80-1.06) or for the initial biopsy (56.8% vs 64.0%, relative sensitivity 0.93, 95% CI 0.79-1.11). For the core-by-core analysis, more positive cores were detected by RTE-targeted biopsy than systematic biopsy (21% vs 11%, relative sensitivity 2.17, 95% CI 1.61-2.95). The 2 RCTs showed a favorable trend toward greater PCa detection when a combination of systematic biopsies and RTE-targeted biopsies was used than when systematic biopsy alone was used (45.5% vs 39.5%, risk ratio (RR) 1.18, 95% CI 0.98-1.43). CONCLUSION Currently, there is not enough evidence to demonstrate that RTE-targeted biopsy can outperform systematic biopsy, but the combination of systematic and RTE-targeted biopsy may be a promising approach for improving PCa detection.

Abstract
Studies documenting the application of ultrasonography to depict normal and pathological changes in koalas (Phascolarctos cinereus), especially in the male, are scarce. Sixty-two wild koalas were used in this study to define ultrasonographic protocols and features for the assessment of the male koala reproductive tract. Testis, epididymis and spermatic cord were examined using a hockey stick transducer. The normal koala testis showed a homogeneous echogenicity and an obvious hyper-echoic band corresponding to the tunica albuginea. The cauda epididymis was characterised by hypo- and hyper-echoic regions and was most effectively imaged in sagittal section. The koala prostate was assessed using a micro-curved transducer positioned midline, caudal to the bladder. On transverse section, it showed distinct margins and a well-defined internal structure, although the prostatic urethra was not apparent on most scans. To image the bulbourethral glands (BGs), the hockey stick transducer was placed lateral to the cloaca. BGIII was located just below the skin, while BGII was located deeper than BGIII. BGI was too small and not sufficiently echogenic to be detected. The ultrasonographic appearance of the BGs was similar to that of the testes but with more obvious hypo-echoic stippling. This comprehensive review of the ultrasonographic appearance of normal male koala reproductive tract can be used by veterinarians and others, in zoos or those working with wild koalas, during assessment of the reproductive tract of male koalas in relation to seasonal changes in accessory gland function or for the pathological investigation of reproductive lesions and infertility problems.

Abstract
A retrospective observational study was undertaken to gain new insight into the relationship between total testicular volume and levels of serum testosterone, luteinising hormone, follicle-stimulating hormone, prolactin and clinical variables. A total of 312 men with sexual dysfunction or infertility were divided into groups A and B (156 each) on the basis of basal plasma testosterone ≤5 nmol/L of ≥12 nmol/L respectively. Group A was subclassified in A1 (primary hypogonadism) and A2 (secondary hypogonadism). There were significant differences in total testicular volume between group A (15.33 ± 11.94 ml) and group B (36.74 ± 6.9; p < .001) and also between subgroup A1 (11.07 ± 8.49 ml) and subgroup A2 (23.62 ± 13.04 ml; p < .001). Only 13.5% of patients in group B had a total testicular volume <30 ml. Differences in all studied parameters were found between group A and group B. There were no variations when comparing age, body mass index and testosterone in groups A1 and A2 . The use of total testicular volume and body mass index together for predicting testosterone levels yields a sensitivity and specificity of 85.3% and 86.5% respectively. Logistic regression analysis, univariate and multivariate models, using the measurement of total testicular volume resulted in a high capacity to predict testosterone levels.

Abstract
PURPOSE Prostatitis is a very common urogenital disease of the male with prevalence ranging from 2.2 to 9.7% worldwide. Interestingly, some recent evidences have showed a significant association between chronic prostatitis (CP) and male infertility including a detrimental effect on sperm parameters, reduction of zinc concentration on semen sperm and production of anti-semen antibodies (ASAs). The aim of the current meta-analysis was to evaluate the association between CP and alteration of semen parameters. METHODS This analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines and we included in the final analysis 27 studies, with a total of 3241 participants, including 381 (11.75%) with chronic bacterial prostatitis (CBP), 1670 (51.53%) with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and 1190 (36.72%) controls. RESULTS CBP was associated with reduction of sperm concentration, sperm vitality, sperm total and progressive motility, while CP/CPPS was related to the reduction of semen volume, sperm concentration, sperm progressive motility and sperm normal morphology. We found that CP was significantly associated with reduced zinc concentration on seminal plasma (SMD: -20.73; p = 0.005). Finally, CP statistically increased the risk of developing ASA on seminal plasma (OR 3.26; p < 0.01). CONCLUSION In conclusion, chronic prostatitis showed a detrimental effect on sperm and both CPB or CP/CPPS may differently show negative impact on sperm.

Abstract
PURPOSE A continuous spermatic venous reflux (SVR) at colour Doppler ultrasound (CDU) is an evidence for varicocele, a frequent correlate for male subfertility. We explored whether SVR after left varicocele repair is predictive for changes in semen quality in subfertile men. METHODS Blood hormones (FSH, LH, and total testosterone) and scrotal CDU were obtained in subfertile patients with left grade II or grade III varicocele on physical evaluation and a poor sperm quality. Semen analysis and CDU were re-evaluated 6 months after a retrograde internal spermatic vein scleroembolisation. RESULTS The retrospective study included 100 men with a baseline SVR >3 cm/s; 60 men showed a disappearance (group 1) and 40 men (group 2) showed a reduced SVR after varicocele repair. Total motile sperm count (TMC) was markedly increased after treatment (p < 0.0001; F = 35.79) and the increase was more relevant in group 1 compared to group 2 (p = 0.04; F = 4.20). TMC and left SVR values after varicocele repair were negatively correlated (R = -0.218; p = 0.035). Multivariate analysis showed that adjusted SVR after repair negatively predicted TMC change (TMC after repair minus baseline TMC) (ß = -2.56; p = 0.022). Disappearance of a continuous left SVR at CDU after varicocele repair was associated to a better improvement of semen parameters in subfertile men. CONCLUSION Recording of a continuous left spermatic vein reflux is an objective method to assess a successful varicocele repair aimed to improve sperm parameters in subfertile men.

Abstract
BACKGROUND Men with chronic obstructive pulmonary disease, have reduced endogenous testosterone levels, but the relationship between pulmonary function and endogenous testosterone levels, is inconsistent. Testicular volume is a known indicator of endogenous testosterone levels, male fertility, and male potency. In the present study, the authors investigated the relationship, between testicular volume and lung function. METHODS One hundred and eighty-one South Korean men age 40-70, hospitalized for urological surgery, were retrospectively enrolled, irrespective of the presence of respiratory disease. Study subjects underwent pulmonary function testing, prior to procedures, and testicular volumes were measured by orchidometry. Testosterone levels of patients in blood samples collected between 7 AM and 11 AM, were measured by a direct chemiluminescent immunoassay. RESULTS The 181 study subjects were divided into two groups, by testicular volume (≥35 mL vs. <35 mL), the larger testes group, had better lung functions (forced vital capacity [FVC]: 3.87±0.65 L vs. 3.66±0.65 L, p=0.037; forced expiratory volume in 1 second [FEV₁]: 2.92±0.57 L vs. 2.65±0.61 L, p=0.002; FVC % predicted: 98.2±15.2% vs. 93.8±13.1%, p=0.040; FEV₁ % predicted: 105.4±19.5% vs. 95.9±21.2%, p=0.002). In addition, the proportion of patients with a FEV₁/FVC of <70%, was lower in the larger testes group. Univariate analysis conducted using linear regression models, revealed that testicular volume was correlated with FVC (r=0.162, p=0.029), FEV₁ (r=0.218, p=0.003), FEV₁/FVC (r=0.149, p=0.046), and FEV₁ % predicted (r=0.178, p=0.017), and multivariate analysis using linear regression models, revealed that testicular volume was a significant predictive factor for FEV₁ % predicted (β=0.159, p=0.041). CONCLUSION Larger testicular volume was independently associated, with favorable indices of lung function. These results suggest that androgens, may contribute to better lung function.

Abstract
PURPOSE We report the safety of surveillance of small testicular masses incidentally discovered during evaluation of male infertility. MATERIALS AND METHODS We retrospectively reviewed a prospectively collected database to identify patients with male infertility found to have incidental small testicular masses (hypoechoic lesions less than 10 mm) on scrotal ultrasound. The men were offered close surveillance with interval imaging and office followup. Patient and imaging characteristics were collected to compare the surveillance and surgical groups with additional comparisons between benign and malignant pathologies to elucidate predictors of underlying malignancy. RESULTS Of 4,088 men in whom scrotal ultrasound was completed for male infertility evaluation 120 (2.9%) were found to have a subcentimeter testicular mass. Average followup was 1.30 years (range 0.1 to 16.9). A total of 18 men (15%) proceeded to extirpative surgery while 102 remained on surveillance at last followup. In those with at least 1 month of followup the mean lesion growth rate was -0.01 mm per year. Reasons for surgery included testicular exploration for infertility, mass growth, positive tumor markers, history of testis cancer, concerning imaging characteristics and patient choice. Six of the 18 men who underwent surgery were found to have malignancy, which was seminoma in all. All malignant lesions were greater than 5 mm on initial imaging and demonstrated vascularity, although size and vascularity were not significantly different from those of benign lesions on final pathology findings. No patients demonstrated advanced or recurrent disease. CONCLUSIONS Small testicular masses are not uncommon, especially in the infertile male population. Most of these masses do not show significant growth during long-term evaluation and can be safely surveilled with close followup.

Abstract
Background There are limited studies about testicular microlithiasis (TML) and background information such as health, lifestyle, and socioeconomic status. Purpose To assess the prevalence of TML in relation to socioeconomic status and ethnicity. Material and Methods From a database of scrotal ultrasound examinations in a single institution, all men who underwent routine ultrasound examinations for a variety of symptoms from 1998 to 2015 were included. Skilled observers performed all examinations, and presence of any form of intra-testicular calcification, including TML, was recorded on the examination report and a representative image obtained and stored. A total of 1105 cases with TML were reviewed and random sample of 1105 controls from the same database was also reviewed. Demographics were recorded including ethnicity (white, black, and others) and socioeconomic groups (IMD Quintile). Results Black men had increased prevalence of TML (odds ratio [OR] = 2.17, 95% confidence interval [CI] = 1.72–2.75) compared with white men. Among the 1105 TML cases, 423 (38.3%) were white, 273 (24.7%) black, 152 (13.8%) had other ethnicities, and 257 (23.2%) had no ethnicity recorded. In the control group of 1105 men without TML, 560 (50.7%) were white, 171 (15.5%) black, 111 (10.0%) had other specified ethnicities, and 263 (23.8%) had no ethnicity recorded. Men from the most deprived socioeconomic groups had higher prevalence of TML than men in the most affluent groups, with a trend in OR from the least deprived to the most deprived group. Conclusion Pathogenesis and clinical relevance of TML is unknown but our results point towards possible ethnic and socioeconomic variation in the underlying causes of TML.

Abstract
BACKGROUND AND OBJECTIVE Although several epidemiological studies have been conducted, the impact of follicle-stimulating hormone receptor (FSHR) polymorphisms on male infertility remains unclear. The aim of this study was to investigate the prevalence of specific FSHR single nucleotide polymorphisms (SNPs) in the Greek population and associate the latter with the clinical phenotype. PATIENTS AND METHODS We enrolled 96 subjects: men with idiopathic non-obstructive azoospermia (n = 78) were compared with a control group of fertile men (n = 18) for SNPs in FSHR positions c.-29, c.566, c.919, and c.2039. The SNP in position 566 (c.566C > T) was assessed by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) and the other three SNPs (c.-29G > A, c.919A > G, c.2039A > G) with single-strand conformation polymorphism (SSCP); all of them were validated with DNA sequence. RESULTS No polymorphisms were detected in positions c.-29 and c.919 (c.-29G > A, c.919A > G). The heterozygous SNP (AG) at position 2039 was associated with different size of the right testis (p = 0.008). There was no association between the c.566C > T SNPs polymorphism and hormonal or semen parameters. The combination SNP 2039 AA with 566 CT revealed significant association with FSH and LH concentrations. CONCLUSIONS FSHR SNPs at positions c.-29, c.566, c.919, and c.2039 (c.-29G > A, c.566C > T, c.919A > G, c.2039A > G) do not appear to play specific roles in male infertility. Larger studies are needed to confirm these results.

Abstract
An accurate medical history and directed physical examination are essential in diagnosis of male infertility. We review the hormonal assessments and specific genetic analyses that are useful additional tests, and detail other evidence-based examinations that are available to help guide therapeutic strategies. By contrast with female infertility treatments-especially hormonal manipulations to stimulate or enhance oocyte production-spermatogenesis and sperm quality abnormalities are much more difficult to affect positively. In general, a healthy lifestyle can improve sperm quality. A few men have conditions in which evidence-based therapies can increase their chances for natural conception. In this second of two papers in The Lancet Diabetes and Endocrinology Series on male reproductive impairment, we examine the agreements and controversies that surround several of these conditions. When we are not able to cure, correct, or mitigate the cause of conditions such as severe oligozoospermia, non-remedial ductal obstruction, and absence of sperm fertilising ability, assisted reproductive technologies, such as in-vitro fertilisation (IVF) with intracytoplasmic sperm injection (ICSI), can be used as an adjunctive measure to allow for biological paternity. Not considered possible just two decades ago, azoospermia due to testicular failure, including 47,XXY (Klinefelter syndrome), is now treatable in approximately 50% of cases when combining surgical harvesting of testicular sperm and ICSI. Although genetic fatherhood is now possible for many men previously considered sterile, it is crucial to discover and abrogate causes as best possible, provide reliable and evidenced-based therapy, consider seriously the health and wellness of any offspring conceived, and always view infertility as a possible symptom of a more general or constitutional disease.

Abstract
Individuals who smoke generally do so with the knowledge of potential consequences to their own health. What is rarely considered are the effects of smoking on their future children. The objective of this work was to review the scientific literature on the effects of paternal smoking on sperm and assess the consequences to offspring. A literature search identified over 200 studies with relevant data in humans and animal models. The available data were reviewed to assess the weight of evidence that tobacco smoke is a human germ cell mutagen and estimate effect sizes. These results were used to model the potential increase in genetic disease burden in offspring caused by paternal smoking, with specific focus on aneuploid syndromes and intellectual disability, and the socioeconomic impacts of such an effect. The review revealed strong evidence that tobacco smoking is associated with impaired male fertility, and increases in DNA damage, aneuploidies, and mutations in sperm. Studies support that these effects are heritable and adversely impact the offspring. Our model estimates that, with even a modest 25% increase in sperm mutation frequency caused by smoke-exposure, for each generation across the global population there will be millions of smoking-induced de novo mutations transmitted from fathers to offspring. Furthermore, paternal smoking is estimated to contribute to 1.3 million extra cases of aneuploid pregnancies per generation. Thus, the available evidence makes a compelling case that tobacco smoke is a human germ cell mutagen with serious public health and socio-economic implications. Increased public education should be encouraged to promote abstinence from smoking, well in advance of reproduction, to minimize the transmission of harmful mutations to the next-generation.

Abstract
A 34-year-old male presented with an 8-month history of passing increasingly painful 'grit' in his ejaculate. Semen analysis was normal as were urinary and blood tests. T1-weighted MRI revealed several bilateral high-signal areas measuring up to 1 cm in diameter, located in the seminal vesicles. These were confirmed as calculi on T2-weighted imaging and a seminal vesiculogram, with no drainage from the left ejaculatory duct and only minimal from the right duct. He is currently awaiting a robot-assisted laparoscopic vesiculotomy after completion of family.

Abstract
BACKGROUND Infections of the genital tract are considered common causes of male fertility disorders, with a prevalence of 6-10%. Most of the affected men are asymptomatic. The diagnostic evaluation is based mainly on laboratory testing. Inconsistent diagnostic criteria have been applied to date, and this may explain the controversial debate about the role of infection and inflammation in the genital tract as a cause of infertility. The risk of an irreversible fertility disorder should not be underestimated. METHODS This review is based on pertinent publications retrieved by a selective literature search in PubMed, including guidelines from Germany and abroad and systematic review articles. RESULTS The main causes of inflammatory disease of the male genital tract are ascending sexually transmitted infections (STIs) and uropathogens. Chronic prostatitis has no more than a limited influence on ejaculate variables. By contrast, approximately 10% of men who have had acute epididymitis develop persistent azoospermia thereafter, and 30% have oligozoospermia. Obstruction of the excurrent ducts can ensue, as can post-infectious disturbances of spermatogenesis. The differential diagnostic evaluation includes the determination of testicular volumes, hormone concentrations, and ejaculate variables. Epidemiological data are lacking with regard to infertility after primary orchitis of infectious origin; however, up to 25% of testicular biopsies obtained from infertile men reveal focal inflammatory reactions. Multiple studies have suggested a deleterious effect of leukocytes and inflammatory mediators on sperm para - meters. On the other hand, the clinical significance of bacteriospermia remains unclear. CONCLUSION Any suspicion of an infectious or inflammatory disease in the male genital tract should prompt a systematic diagnostic evaluation and appropriate treatment. For patients with obstructive azoospermia, the etiology and site of the obstruction determine the surgical approach to be taken. In the near future, the elucidation of underlying pathophysiological mechanisms and the identification of suitable biomarkers may enable new strategies for conservative treatment.
