RESUMO

BACKGROUND: Management of the adolescent varicocele focuses on optimizing fertility potential, but to date there is limited data on the success of varicocelectomy on optimizing semen parameters for individual adolescent patients. We reviewed our database of over 1600 adolescent varicocele patients to find those with pre- and postoperative semen analyses to determine the impact of varicocele correction. METHODS: 15 Tanner stage V patients with unilateral clinically apparent left-sided with pre- and postoperative semen analyses were identified. Mixed models were used to compare semen parameters pre- and post-varicocelectomy in patients with successful management. RESULTS: Complete elimination of the varicocele was achieved in 12/15 (80%) patients. Three patients had persistent varicocele (with down-grading in two) and declined further intervention. Median time between pre- and postoperative semen analyses was 24.2 months. For those with successful varicocele correction, total motile sperm count (TMSC) improved in all but one (Figure 1), with an average increase of 44.0 million (95% CI: 18.7-69.3) in post-varicocelectomy analyses compared to pre-varicocelectomy (p = 0.0016). Mean percent improvement was 649.2%. It went from abnormal to normal (≥20 million/cc) in 55.6% (5/9). For the three patients with persistent varicocele, one had improved TMSC from abnormal to normal range, one had worsening within normal range, and one had effectively no change. CONCLUSION: Successful correction of adolescent varicocele may improve TMSC. In over half of our institution's cases, an abnormal value normalized. Surgical intervention may be considered for adolescent varicoceles associated with abnormal semen parameters. LEVELS OF EVIDENCE: Level III. TYPE OF STUDY: Treatment study.

RESUMO

OBJECTIVE: To investigate the prevalence and treatment rates of low testosterone (T) in men with cystic fibrosis (CF). CF is a genetic disease with highly variable presentation that results from a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Phenotypic manifestations of CF include alterations in function of the lungs, liver, pancreas, and reproductive system. Despite the well-described association between CF and infertility secondary to congenital bilateral absence of the vas deferens (CBAVD), men with CF report further sexual and reproductive health concerns, many of which are often associated with low testosterone. METHODS: We queried the TrinetX database for men over 18years old with CF or CBAVD to assess what percentage of men had a T level measured, and if hypogonadal (below 300 ng/dL), what percentage received T therapy (TT). We hypothesized that low T would be under-evaluated in the CF population. RESULTS: Serum T levels were measured in 10.1% of men with CF and 8.9% of men with CBAVD. Within each group, 464 men with CF (32.7%) and 132 with CBAVD (43.0%) demonstrated low T. The majority of men with T < 300 ng/dL went on to appropriately receive TT: 59.3% of men with CF and 78% with CBAVD. CONCLUSION: Our data suggests that hypogonadism is highly prevalent in men with CF and CBAVD. Investigation and appropriate treatment of testosterone deficiency may significantly improve quality of life.

RESUMO

Background: The impact of Chlamydia trachomatis on semen quality has been studied with varied results. Aim: To determine the prevalence of antichlamydial antibodies and their relationship with sperm quality among male partners of infertile couples in Enugu, South-East Nigeria. Materials and Methods: It was a cross-sectional study of infertile male partners of couples attending infertility clinics at the University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu, Nigeria. Their sera were assayed for antichlamydial antibodies, and semen analysis and culture were done for each participant. Results: Two hundred and eighty-two (282) male partners of infertile couples were studied. Infertility was commoner among participants aged 40 years or more (45.1%) and was mainly of the "primary type" (62.1%). Antichlamydia antibody was detected in 156 (55.3%) participants and was significantly associated with sperm quality (P = 002; OR = 2.294; 95% CI = 1.36-3.88). Overall, 81 (28.7%) had abnormal sperm quality. The sperm count, progressive motility, and vitality were significantly lower in participants with abnormal sperm quality than those with normal sperm quality (P < 0.001) while morphology, volume, and liquefaction time did not differ significantly (P > 0.05). Staphylococcus aureus was the predominant organism isolated from culture (122/282, 43.3%) while Streptococcus species were the least (4/262, 1.4%). There was significantly more Staphylococcus aureus isolated from the semen of participants that were seropositive to antichlamydial antibodies than those that were seronegative (80/156, 51.3% vs. 42/126, 33.3%; OR = 2.105; 95% CI = 1.30-3.42; P = 0.003). Conclusion: The prevalence of antichlamydial antibodies among male partners of infertile couples in Enugu, Nigeria is high and there is a significant association with sperm quality, sperm count, and bacterial isolates in seminal culture. Male partners of infertile couples in Enugu should be screened for antichlamydial antibodies and appropriate treatment offered wherever indicated. There is a need for increased public awareness and advocacy campaigns on the impact of Chlamydia infection on male factor infertility. This primary preventive measure may help in reducing the burden of Chlamydia infection and male factor infertility.

RESUMO

Up to 50% of infertility is caused by the male side. Varicocele, orchitis, prostatitis, oligospermia, asthenospermia, and azoospermia are common causes of impaired male reproductive function and male infertility. In recent years, more and more studies have shown that microorganisms play an increasingly important role in the occurrence of these diseases. This review will discuss the microbiological changes associated with male infertility from the perspective of etiology, and how microorganisms affect the normal function of the male reproductive system through immune mechanisms. Linking male infertility with microbiome and immunomics can help us recognize the immune response under different disease states, providing more targeted immune target therapy for these diseases, and even the possibility of combined immunotherapy and microbial therapy for male infertility.

RESUMO

Infertility affects 15% of couples worldwide and in approximately 50% of cases the cause is secondary to an abnormality of the sperm. However, treatment options for male infertility are limited and empirical use of hormone stimulation has been utilised. We review the contemporary data regarding the application of hormone stimulation to treat male infertility. There is strong evidence supporting the use of hormone stimulation in hypogonadotropic hypogonadism but there is inadequate evidence for all other indications.

RESUMO

Evaluation of a man presenting for couple infertility starts with obtaining a thorough medical history, and the couple's reproductive and sexual history. Semen analysis, according to World Health Organization recommendations, is the cornerstone of male partner evaluation. A comprehensive physical examination is essential for every male partner, with adequate assessment of the development of secondary sexual characteristics. However, more complex testing than semen analysis (eg, sperm DNA fragmentation index) may be required in selected cases. For men with oligozoospermia or azoospermia, a hormonal evaluation should be performed, including at least total testosterone, follicle stimulating hormone, and luteinising hormone. Genetic testing should be offered to azoospermic men and those with severe oligozoospermia. Ultrasound of the genitourinary tract can provide additional information in select cases. PATIENT SUMMARY: A complete medical history, physical examination, and semen analysis are essential components of the initial evaluation of men being assessed for infertility. The evaluation must proceed in parallel for male and female partners to optimise management for infertile couples.

RESUMO

There is increasing evidence that Chlamydia trachomatis (CT) infection can directly affect male fertility. However, only few have investigated the effects of CT on semen parameters, and mostly with inconclusive results. The main aims of this study were to identify CT inside spermatozoa, and the possible pre and post antibiotic treatment effects on the overall semen parameters. We developed a flow cytometric method for the detection of CT inside spermatozoa (SPI™). Briefly, sperm cells were fixed, membrane permeabilized and DNA was loosened using DNAse. Sperm cells were incubated with a primary monoclonal antibody against CT and with a secondary fluorescent antibody (vs primary), and analysed using a flow cytometer. Of 2415 infertile individuals, 48.61% were found positive for CT. 170 CT+ samples were included in the CT antibiotic treatment study. 78.82% (134/170) of the CT+ showed a significant reduction in the percentage of the iCT infected spermatozoa after the antibiotic treatment; 59.70% (80/134) decreased to non-detectable levels. Spermcount data were also recorded. Spermatozoa morphology (normal and teratozoospermia index, TZI) and motility (fast progressive and non-progressive spermatozoa) were statistically significant altered in CT+ pre-treatment vs control group. CT antibiotic treatment showed statistically significant effects on normal spermatozoa morphology, mid-piece and tail defects, and TZI. The study demonstrated that semen flow cytometric analysis of semen could be a valuable tool for faster and accurate identification of individuals with asymptomatic CT infection. It also identified a positive effect of antibiotic therapy on semen parameters, that could help males with infertility.

RESUMO

BACKGROUND: Elevated intrascrotal temperature has been suggested as a risk factor for testicular cancer, which is the most common neoplasm among young men. Varicocoele was linked to increased intrascrotal temperature, but whether it is associated with testicular cancer is unclear. OBJECTIVE: To explore the possible association between varicocoele at adolescence and the incidence of testicular cancer at adulthood. DESIGN, SETTING, AND PARTICIPANTS: This nationwide, population-based, historical cohort study includes 1,521,661 Israeli male adolescents (mean age 17.5 ± 0.4 years), who were screened for varicocoele during the years 1967-2012, as part of their medical assessment prior to compulsory military service. The mean follow-up was 18 ± 4.2 years. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The diagnosis of testicular cancer was ascertained from linkage of records to the the Israeli National Cancer Registry. Survival analysis was applied. RESULTS: In total, 53,210 adolescents were diagnosed with varicocoele stages 2 and 3 prior to military service. Of 1988 (0.13% of the total cohort) men who were diagnosed with testicular cancer during follow-up, 54 (0.1%) had varicocoele prior to military service, while 1934 (99.9%) did not; p = 0.213. The age at cancer diagnosis and the distribution of seminomas versus non-seminomas did not differ significantly between those with and without varicocoele in adolescence. In a multivariable analysis controlling for sociodemographic factors, varicocoele was not associated with testicular cancer; odds ratio = 0.816 (CI: 0.615-1.083). CONCLUSIONS: Varicocoele in adolescents was not found to be associated with testicular cancer in young adults. PATIENT SUMMARY: In light of the theoretical association between varicocoele and testicular cancer, we conducted this large population study. We found no association between varicocoele in young adulthood and testicular cancer later in life.

RESUMO

BACKGROUND: Varicocoele is a common risk factor associated with reduced male fertility potential. The current understanding of varicocoele pathophysiology does not completely explain the clinical manifestation of infertility. The present treatment options such as antioxidant supplementation and varicocoelectomy only help ≈35% of men to achieve spontaneous pregnancy. OBJECTIVE: This review aims to summarize the available knowledge on cellular and molecular alterations implicated to varicocoele-associated male infertility and also highlights the new knowledge generated by "omics" technologies. MATERIALS AND METHODS: PubMed, MEDLINE, Cochrane and Google Scholar databases are searched using different combinations of keywords (varicocoele, infertile/fertile men with varicocoele, cellular changes, molecular mechanisms, proteome, epigenome, transcriptome and metabolome). A total of 229 relevant human and animal studies published till 2021 were included in this review. RESULTS: Current understanding advocates oxidative stress (OS) as a major contributory factor to varicocoele-associated male infertility. Excessive OS causes alteration in testicular microenvironment and sperm DNA fragmentation, which further contributes to infertility. Molecular and omics studies have identified several promising biomarkers such as AAMP, SPINT1, MKI67 (genetic markers), sperm quality and function related protein markers, global sperm DNA methylation level (epigenetic marker), Hspa2, Protamine, Gadd7, Dynlt1 and Beclin1 (mRNA markers), PRDX2, HSPA, APOA2, YKL40 (seminal protein markers), total choline and PHGDH (metabolic markers). DISCUSSION: Mature spermatozoa harbours a plethora of molecular information in form of proteome, epigenome and transcriptome, which could provide very important clues regarding pathophysiology of varicocoele-associated infertility. Recent molecular and omics studies in infertile men with varicocoele have identified several promising biomarkers. Upon further validation with larger and well-defined studies, some of these biomarkers could aid in varicocoele management. CONCLUSION: The present evidences suggest that inclusion of OS and sperm DNA fragmentation tests could be useful to the diagnostic workup for men with varicocoele. Furthermore, including precise molecular markers may assist in diagnostics and prognostics of varicocoele-associated male infertility.

RESUMO

Men with diabetes have negative effects on reproduction that causes sexual dysfunction. Medicinal plants are non-toxic and much safer than synthetic drugs because regular use of synthetic drugs shows long-term side effects. Curcuma amada (Roxb) is a medicinal plant used in Ayurveda and Unani medicinal systems in India. The goal of this study is to rummage the potential efficiency of the most potent solvent fraction of effective extract of hydro-methanol 60:40 of C. amada rhizome on male gonadal hypofunction in streptozotocin-induced diabetic rat. Diabetes-induced testicular hypofunction was evaluated by glycemic, spermiological, biochemical, genomic, flow cytometric, and histology of testicular tissue. The n-hexane, chloroform, ethyl-acetate, and n-butanol solvent fractions of the said extract were administrated for 4 weeks at 10 mg dose/100 g body weight/day. Among all the used fractions, the ethyl-acetate solvent fraction-treated group showed maximum recovery in serum insulin (177.42%), sperm count (92.84%), sperm motility (97.15%), and serum testosterone (164.33%). The diabetic rats treated with ethyl-acetate solvent fraction also exhibited the maximum resettlement in flow cytometric analysis of sperm viability (55.84%) and sperm mitochondrial integrity (149.79%), gene expression patterns of key markers for androgenesis (Δ5, 3ß-HSD 87.50%, and 17ß-HSD 74.66%) and apoptosis (Bax 44.63%, Bcl-2 54.03%, and Caspase-3 35.77%) along with testicular histology. The ethyl-acetate fraction contains alkaloids, flavonoids, and polyphenols where all of these components are not present in other fractions, may be the most effective cause for the recovery of diabetes-linked oxidative stress-mediated testicular hypofunctions. PRACTICAL APPLICATIONS: Nowadays worldwide, the use of synthetic drugs are reduced due to their toxic effect. At present, synthetic drugs are replaced by several herbal drugs, the natural source of medicine which has many therapeutic values. C. amada has strong antioxidant activity due to the presence of bio-active compound(s) that can able to manage streptozotocin-induced diabetes linked to oxidative damage of male gonadal organs. Therefore, these bio-active compound(s)-containing said medicinal plant may use as a good source of antioxidative food in the food industry as nutraceuticals and in pharmaceutical industries for the development of the herbal drug to manage diabetes-linked male gonadal hypofunctions. At present, WHO also gives emphasis for developing one drug-multi-disease therapy. From such a viewpoint, this active fraction-containing phytomolecules may have corrective efficacy against diabetes as well as oxidative stress-linked testicular complications.

RESUMO

The permanent exposure to environmental contaminants promoting weight gain (i.e., obesogens) has raised serious health concerns. Evidence suggests that obesogens are one of the leading causes of the marked decline in male fertility and are key players in shaping future health outcomes, not only for those who are directly exposed to them, but also for upcoming generations. It has been hypothesized that obesogens affect male fertility. By using an interdisciplinary strategy, combining in silico, in vitro, in vivo and epidemiological findings, this review aims to contribute to the biological understanding of the molecular transformations induced by obesogens that are the basis of male infertility. Such understanding is shaped by the use of Adverse Outcomes Pathways, a new approach that may shift the paradigm of reproductive toxicology, contributing to the improvement of the diagnosis and management of the adverse effects of obesogens in male fertility.

RESUMO

Hypogonadism can be present in up to 40% in men who present with couple infertility. Testosterone is the major androgen regulating-spermatogenesis in men; as a result, men with either primary or secondary hypogonadism may be subfertile because of impaired spermatogenesis. The clinical impact of hypogonadism on fertility potential depends on the timing of its onset (fetal, prepubertal, or postpubertal) and effect on semen parameters. Treatment pathways and success rates differ according to the cause of hypogonadism and the time of its onset. When medical therapy fails to induce sufficient sperm, assisted reproductive technologies are considered.

RESUMO

Chlamydia trachomatis is an obligate, intracellular bacterium responsible for a range of diseases of public health importance, since C. trachomatis infection is often asymptomatic and, hence, untreated, leading to chronic complications, including prostatitis, infertility, and reactive arthritis. The ample spectrum of diseases caused by C. trachomatis infection is reflected in its ability to infect and multiply within a wide range of different cell types. Cervical epithelial cells, to date, have been the most studied cellular infection model, highlighting the peculiar features of the host-cell inflammatory and immune responses to the infection. Herein, we provide the up-to-date evidence on the interaction between C. trachomatis and human prostate epithelial, Sertoli and synovial cells.

RESUMO

This study aimed to confirm the expression of the seminal plasma long noncoding RNAs (lncRNAs) microRNA210 host gene (MIR210HG) in varicocele (VC) patients, to further explore the association between MIR210HG and VC severity and to evaluate whether MIR210HG can predict VC-related dyszoospermia. Semen samples from 188 VC patients and 92 healthy men were collected. Quantitative reverse transcriptase PCR detected seminal plasma MIR210HG levels. Receiver operating characteristic analysis assessed the ability of MIR210HG to screen patients with VC, or to screen VC patients with abnormal semen quality. Logistic analysis assessed the value of MIR210HG in predicting dyszoospermia in VC patients. The levels of MIR210HG in seminal plasma of VC patients were upregulated, which could screen VC patients. In addition, the levels of seminal plasma MIR210HG were upregulated with VC severity and were downregulated at 6 months after surgery in VC patients. Moreover, elevated MIR210HG levels in VC patients with abnormal semen quality could screen patients with abnormal semen quality and could independently predict the occurrence of dyszoospermia in VC patients. Seminal plasma MIR210HG expression is upregulated in VC patients, is associated with the severity of VC and may function as an independent predictor of VC-related dyszoospermia.

RESUMO

ABSTRACT: This study is to investigate the effect of high serum uric acid (UA) level on oxidative stress and semen quality of male infertility patients.A cohort of 654 male individuals aged between 20 and 45 years old were included in this study, and their semen and venous blood samples were collected. The serum UA, blood glucose, blood lipids, and hormone levels were determined by chemiluminescence method. The changes in inflammatory factors, oxidative stress, adipokines, and biochemical indices in seminal plasma were determined by ELISA. Organic acids in seminal plasma were detected with reversed-phase ultra high performance liquid chromatography.Compared with the control group, the amount of semen and the total number of sperm in the hyperuricemia group significantly reduced (P < .05). Semen volume decreased with the increase of serum UA level, and the total number of sperm also decreased. The level of luteinizing hormone increased and the level of testosterone decreased in the hyperuricemia group. The concentration of superoxide dismutase decreased and the concentration of endothelin increased in the hyperuricemia group (P < .05). The concentration of seminal plasma α-glucosidase and alkaline phosphatase in the hyperuricemia group decreased significantly (P < .05). Compared with the control group, the contents of ascorbic acid, tartaric acid, lactic acid, and UA in the seminal plasma were significantly reduced in the hyperuricemia group (P < .05).Blood UA level may become a new risk predictor of semen quality in infertile men.

RESUMO

Male infertility is one of the most common diseases in andrology. Studies show that male infertility is significantly correlated with the incidence and mortality of tumors, especially malignant tumors in the genitourinary system, such as testis cancer and prostate cancer. The relationship of male infertility with genitourinary system tumors involves various aspects, mainly including changes in chromosome mutations, epigenetic marks, hormonal imbalance, and congenital deformity. Besides, some chronic diseases are shown to be significantly associated with male infertility, and semen quality or fertility status may be biomarkers of the overall health of males. In-depth studies of the correlation between male infertility and these factors are very important for an insight into the pathogenesis and prevention of the related diseases.

RESUMO

OBJECTIVE: To identify, besides maternal age and the number of previous pregnancy losses, additional characteristics of couples with unexplained recurrent pregnancy loss (RPL) that improve the prediction of an ongoing pregnancy. DESIGN: Hospital-based cohort study in couples who visited specialized RPL units of two academic centers between 2012 and 2020. SETTING: Two academic centers in the Netherlands. PATIENTS: Clinical data from 526 couples with unexplained RPL were used in this study. INTERVENTION(S): None. MAIN OUTCOME MEASURES: The final model to estimate the chance of a subsequent ongoing pregnancy was determined using a backward selection process and internally validated using bootstrapping. Model performance was assessed in terms of calibration and discrimination (area under the receiver operating characteristic curve). RESULTS: Subsequent ongoing pregnancy was achieved in 345 of 526 couples (66%). The number of previous pregnancy losses, maternal age, paternal age, maternal body mass index, paternal body mass index, maternal smoking status, and previous in vitro fertilization/intracytoplasmic sperm injection treatment were predictive of the outcome. The optimism-corrected area under the receiver operating characteristic curve was 0.63 compared with 0.57 when using only the number of previous pregnancy losses and maternal age. CONCLUSIONS: The identification of additional predictors of a subsequent ongoing pregnancy after RPL, including male characteristics, is significant for both clinicians and couples with RPL. At the same time, we showed that the predictive ability of the current model is still limited and more research is warranted to develop a model that can be used in clinical practice.

RESUMO

Obesity in both women and men is regarded as one of the many factors that may contribute to impaired reproductive health. Obesity can be accompanied by several neuroendocrine and ovarian dysfunctions, including chronic oligo/anovulation, menstrual irregularities, subfertility, and the increased risk of pregnancy in women. Insulin resistance, elevated triglyceride and fatty acid levels, and the secretion of adipocytokines caused by the excessive accumulation of adipose tissue associated with obesity adversely affect reproductive functions. Alterations in sperm quality and motility and hormone levels related to a rise in body mass index (BMI) may predispose men to infertility. The mechanisms of action of obesity on male infertility include endocrinopathy, erectile dysfunction, epididymitis, increased leptin and adipocytes, increased aromatase, inflammatory cytokines secreted by fat tissue, and sperm DNA fragmentation. This study reports that an increased BMI may lead to low semen quality, poor sperm motility, and reduced fertilization rates in men as well as anovulation, pregnancy loss, diminished pregnancy, and low live birth rates in women. Having optimal weight with balanced nutrition enables one to maintain a continuity of reproductive health throughout the entire life cycle, which is extremely important in terms of having a healthy embryo, including pre-foetal life, in the continuity of pregnancy and having a live birth.

RESUMO

BACKGROUND: A severe male infertility factor has been associated with both lower health status and increased mortality in infertile men. OBJECTIVES: To investigate reproductive factors associated with health status impairment in infertile men over a 10-year time frame since the first clinical evaluation. MATERIALS AND METHODS: Data from 899 infertile men were analysed at baseline between 2003 and 2010. Health-significant comorbidities were scored with the Charlson Comorbidity Index. Patients were followed up yearly recording any worsening in their health status until 2019. Cox regression models were used to estimate hazard ratios and 95% confidence intervals of Charlson Comorbidity Index score increase. RESULTS: At a median follow-up of 136 months (Interquartile range: 121, 156), 85 men (9.5%) depicted an increase of their baseline Charlson Comorbidity Index score of at least one point. The most frequent reason for Charlson Comorbidity Index upgrade was cancer (34%), cardiovascular diseases (29%) and diabetes mellitus (22%). Compared to patients without a Charlson Comorbidity Index increase, patients with a Charlson Comorbidity Index increase presented with higher body mass index and follicle-stimulating hormone values, a higher rate of baseline Charlson Comorbidity Index ≥ 1 (all p < 0.01) and a greater proportion of non-obstructive azoospermia (p < 0.001). In the Cox regression model, the patient's BMI (p < 0.001), baseline Charlson Comorbidity Index ≥ 1 (p < 0.01) and azoospermia status (p = 0.001) were found to be independently associated with Charlson Comorbidity Index increases. CONCLUSIONS: Almost 10% of men presenting for primary infertility had a decrease of the overall health status already in the relatively short 10-year time frame after the first presentation. Non-obstructive azoospermic men showed the worst health status impairment and should be strictly followed-up regardless of their fertility status.

RESUMO

The impact of sexually transmitted infections (STI) on male fertility is controversial. Aims: To investigate the prevalence of urethritis-associated STIs (chlamydia, gonorrhoeae, Mycoplasma genitalium, trichomoniasis) among infertile males; to analyze the effect of STIs on semen parameters and blood PSA. Case-control study. Study group (n = 2000): males with fertility problems or desire for fertility check. Control group (n = 248): male partners of pregnant women. Analyses: polymerase chain reaction for STI, seminal interleukin 6 (IL-6), semen and fractionated urine, blood analyses (PSA, reproductive hormones). The prevalence of M. genitalium and chlamydia in the study group was 1.1% and 1.2%, respectively. The prevalence of chlamydia in the control group was 1.6%, while there were no M. genitalium cases. No cases with gonorrhoeae or trichomoniasis or combined infections were observed in neither group. There was a higher seminal concentration of neutrophils and IL-6 among M. genitalium positives compared with STI negatives. There was a trend toward a lower total count of spermatozoa and progressive motility among STI positives. No impact of STIs on PSA was found. The prevalence of STIs among infertile males is low. M. genitalium is associated with seminal inflammation. The impact of STIs on semen parameters deserves further investigations.
