Resumo: En los últimos años el estudio de las infecciones de transmisión sexual ha cobrado gran importancia debido principalmente al incremento de estas en parejas heterosexuales y hombres que tienen sexo con hombres. En mujeres existe mucha información de epidemiología y patogénesis de estas infecciones, sin embargo, en hombres la información es muy escasa debido a que la mayoría no presenta sintomatología. En los últimos años se ha evidenciado un creciente interés en el estudio del semen como vía de transmisión, debido principalmente a la afinidad de algunos patógenos con los espermatozoides. Dentro de los principales microorganismos infectantes en semen se encuentran Chlamydia trachomatis, Neisseria gonorrhoeae, Mollicutes, Virus de la Inmunodeficiencia Humana tipos 1 y 2, Virus Herpes Simplex 1 y 2, Virus Papiloma Humano, Virus de la Hepatitis B y C, Citomegalovirus, Virus Epstein-Barr y Trichomonas vaginalis.

Sexually transmitted infections study has become an important issue in these days, mainly due to the increment of heterosexual and men have sex with men partners of people. In women, there is a lot information about epidemiology and pathogenesis of these infections. However, the information is very limited in men, because most infected men are asymptomatic. In recent years, there has been an increasing interest in study of semen as a transmission way, due to the affinity of some pathogens to sperm. The most prevalent microorganisms infecting semen are: Chlamydia trachomatis, Neisseria gonorrhoeae, Mollicutes, Human Immunodeficiency Virus Types 1 and 2 Herpes Simplex Virus 1 and 2, Human Papillomavirus, Hepatitis B and C virus, Cytomegalovirus, Epstein-Barr and Trichomonas vaginalis.

Idioma: en.
Resumo: ABSTRACT Purpose To determine enzymatic antioxidant and lipid peroxidation levels in seminal plasma of patients orchiectomized for testicular tumors. Materials and Methods The study included 52 patients: 26 control men and 26 orchiectomized patients for testicular tumor, of which 12 men had seminoma tumor and 14 men non-seminoma tumor. After semen analysis performed according to the WHO guidelines, an aliquot of semen was centrifuged and the seminal plasma was collected. Lipid peroxidation was performed by thiobarbituric acid reactive substances (TBARS) assay and antioxidant profile was assessed by analyzing catalase, glutathione peroxidase (GPx) and superoxide anion (SOD) activities using colorimetric assays with a standard spectrophotometer. Data were tested for normality and compared using one-way ANOVA (p<0.05). Results Seminoma and non-seminoma groups presented lower sperm concentration and morphology when compared to control group (p=0.0001). Both study groups (seminoma and non-seminoma) presented higher TBARS levels when compared to control group (p=0.0000013). No differences were observed for SOD (p=0.646) andGPx (p=0.328). It was not possible to access the enzymatic activity of catalase in any group. Conclusion Patients with testicular tumor present increased semen oxidative stress, but no differences were observed in antioxidant levels, even after orchiectomy. This indicates that most likely an increased generation of oxidative products takes place in these patients.

Título: Seminal citrate is superior to PSA for detecting clinically significant prostate cancer
Fonte: Int. braz. j. urol;45(6):1113-1121, Nov.-Dec. 2019. tab, graf.
Idioma: en.
Resumo: ABSTRACT Purpose: To establish whether the citrate concentration in the seminal fluid ([CITRATE]) measured by means of high-resolution nuclear magnetic resonance spectroscopy (1HNMRS) is superior to the serum prostate-specific antigen (PSA) concentration in detecting of clinically significant prostate cancer (csPCa) in men with persistently elevated PSA. Materials and Methods: The group of patients consisted of 31 consecutively seen men with histological diagnosis of clinically localized csPCa. The control group consisted of 28 men under long-term follow-up (mean of 8.7 ± 3.0 years) for benign prostate hyperplasia (BPH), with persistently elevated PSA (above 4 ng/mL) and several prostate biopsies negative for cancer (mean of 2.7 ± 1.3 biopsies per control). Samples of blood and seminal fluid (by masturbation) for measurement of PSA and citrate concentration, respectively, were collected from patients and controls. Citrate concentration in the seminal fluid ([CITRATE]) was determined by means of 1HNMRS. The capacities of PSA and [CITRATE] to predict csPCa were compared by means of univariate analysis and receiver operating characteristic (ROC) curves. Results: Median [CITRATE] was significantly lower among patients with csPCa compared to controls (3.93 mM/l vs. 15.53 mM/l). There was no significant difference in mean PSA between patients and controls (9.42 ng/mL vs. 8.57 ng/mL). The accuracy of [CITRATE] for detecting csPCa was significantly superior compared to PSA (74.8% vs. 54.8%). Conclusion: Measurement of [CITRATE] by means of 1HNMRS is superior to PSA for early detection of csPCa in men with elevated PSA.

Título: The association of seminal oxidation reduction potential with sperm parameters in patients with unexplained and male factor infertility
Fonte: Int. braz. j. urol;47(1):112-119, Jan.-Feb. 2021. tab, graf.
Idioma: en.
Resumo: ABSTRACT Purpose: Understanding the effects of high oxidation reduction potential (ORP) levels on sperm parameters will help to identify patients with unexplained and male factor infertility who may have seminal oxidative stress and determine if ORP testing is needed. This study aimed to evaluate the association between seminal ORP and conventional sperm parameters. Materials and Methods: A total of 58 patients who provided a semen sample for simultaneous evaluation of sperm parameters and ORP between January and September 2019 were enrolled in this retrospective study. To identify normal and high ORP levels, a static ORP (sORP) cut-off value of 1.36mV/106sperm/mL was used. Sperm parameters were compared between infertile men with normal sORP (control group, n=23) and high sORP values (study group, n=35). Results: Men with sORP values >1.36mV/106sperm/mL had significantly lower total sperm count (TSC) (p <0.001), sperm concentration (p <0.001) and total motile sperm count (TMSC) (p <0.001). In addition, progressive motility (p=0.04) and fast forward progressive motility (p <0.001) were significantly lower in the study group. A negative correlation was found between sORP and TSC (r=-0.820, p <0.001), sperm concentration (r=-0.822, p <0.001), TMSC (r=-0.808, p <0.001) and progressive motility (r=-0.378, p=0.004). Non-progressive motility positively correlated with sORP (r=0.344, p=0.010). Conclusions: This study has shown that TSC, sperm concentration, progressive motility and TMSC are associated with seminal oxidative stress, indicated by a sORP cut-off of 1.36mV/106sperm/mL. Presence of oligozoospermia, reduced progressive motilty or low TMSC in sperm analysis should raise the suspicion of oxidative stress and warrants seminal ROS testing.

Resumo: ANTECEDENTES: La interacción entre los espermatozoides con algunas especies bacterianas o sus factores solubles influyen en el deterioro de la calidad seminal, alterando la función reproductiva del hombre. OBJETIVO: El objetivo de este trabajo fue determinar el efecto de los factores solubles de Staphylococcus aureus, Staphylococcus capitis y Staphylococcus epidermidis sobre la calidad seminal. MÉTODO: Los factores solubles producto del metabolismo bacteriano de las cepas de S. aureus y S. Capitis sensible a oxacilina y S. aureus y S. Epidermidis resistente a oxacilina se incubaron con las muestras de semen de 20 voluntarios y se cuantificaron los parámetros seminales convencionales y funcionales por microscopía y citometría de flujo, respectivamente. RESULTADOS: Se observó una disminución en la movilidad espermática con los factores solubles de S. aureus, esta disminución fue mayor con la cepa sensible y el efecto negativo sobre la movilidad fue inmediato. Al incubar los espermatozoides con los factores solubles de S. aureus sensible a oxacilina, se afectaron todos los parámetros funcionales excepto la integridad de la cromatina y se observó menor liberación de especies reactivas de oxígeno; con los factores solubles de la cepa de S. aureus resistente a oxacilina se observó una disminución en la lipoperoxidación de membrana y en la expresión de anexina V. CONCLUSIÓN: Este estudio da cuenta del efecto negativo de los factores solubles de la bacteria S. aureus tanto sensible como resistente a oxacilina sobre los parámetros espermáticos convencionales y funcionales, y por ende en su función reproductiva.

BACKGROUND: The interaction between sperm with some bacteria species and their soluble factors are the deterioration of semen quality by altering the reproductive function of man. AIM: The aim of this study was to determine the effect of soluble factors Staphylococcus aureus, Staphylococcus epidermidis and Staphylococcus capitis on semen quality. METHODS: The soluble factors product of bacterial metabolism of the strains of S. aureus and S. capitis methicillin sensitive and S. aureus and S. epidermidis resistant to oxacillin, were incubated with semen samples from 20 volunteers. Subsequently, conventional seminal parameters were measured and functional quantified by microscopy and flow cytometry, respectively. RESULTS: A decrease was observed in sperm motility with soluble factors of S. aureus, this decrease was higher with the sensitive strain that with oxacillin resistant strain and the negative effect on motility was immediate. By incubating the sperm with soluble factor from oxacillin-sensitive S. aureus, all functional parameters were affected except the chromatin integrity and reduced release of reactive oxygen species, mean fluorescence intensity in oxacillin resistant S. aureus strain was decrease in membrane lipid peroxidation and annexin V expression. CONCLUSIONS: This study reports the negative effect of soluble factors of bacteria either S. aureus sensitive and resistant to oxacillin, over conventional and functional sperm parameters, and therefore in their reproductive function.

Resumo: This study aimed to assess the possible occurrence of reproductive changes in male goats associated with ingestion of Cenostigma pyramidale hay. Sixteen animals divided into two experimental groups, G1 and G2 (control group) were used. Animals in G1 received 2% of forage, based on live weight (LW), composed of 100% of C. pyramidale, and animals in G2 received 2% of Panicum maximum "Massai' grass hay, based on LW. Both groups received 1% of concentrated feed supplementation based on LW, along with mineralized salt and water ad libitum. The goats were subjected to weighing, testicular biometry, and semen and blood collection every 30 days. After 120 days, the animals were castrated and their testes were collected. Testicular measurements were performed and fragments were collected for histological processing to determine the gonadosomatic index (GSI), diameter of the seminiferous tubules, height of the germinal epithelium (HGE), volumetric proportion and volume of the testicular parenchyma components, total length of the seminiferous tubules, length of the seminiferous tubules per gram of testis, and leydigosomatic and tubulosomatic indexes. The data were evaluated for normality using the Student's t-test. Data with normal distribution were assessed using analysis of variance (ANOVA) and the non-parametric data were evaluated using the Kruskal-Wallis test, both at 5% probability. Statistically significant differences (p<0.05) were observed for GSI (G1=0.48 ±0.08 and G2=0.34 ±0.09) and HGE (G1=52.95 ±2.99 and G2=.47.63 ±2.67) between treatments. Consumption of C. pyramidale hay increased LW and, consequently, testicular weight, contributing to high GSI. In conclusion, ingestion of C. pyramidale has no toxic effect on the testicular, seminal and histological parameters of goat testis. Due to its nutritional characteristics, consumption of this plant improves animal body development. Because C. pyramidale is adapted to semi-arid regions, it can be an alternative source of feed for goats during periods of shortage.(AU)

Para avaliar a possível ocorrência de alterações reprodutivas em caprinos machos associado ao consumo de Cenostigma pyramidale, foram utilizados 16 animais divididos em dois grupos experimentais, G1 e G2 (grupo controle). Animais pertencentes ao G1 receberam 2% de volumoso, com base no peso vivo (PV), constituído de 100% de C. pyramidale e o G2 receberam 2%, com base no PV, de feno de Panicum maximum 'Massai'. Todos os grupos receberam 1%, com base no PV, de suplementação concentrada, além de sal mineralizado e água ad libitum. A cada 30 dias os animais eram submetidos à pesagem, biometria testicular e coletas de sêmen. O sêmen foi avaliado quanto ao volume, turbilhonamento, vigor, motilidade, concentração espermática, defeitos maiores, menores e totais. Após 120 dias os animais foram castrados e os testículos coletados. Foram realizadas as mensurações testiculares e coletados fragmentos para o processamento histológico, para determinação do índice gonadossomático, diâmetro dos túbulos seminíferos, altura do epitélio germinativo, proporção volumétrica e volume dos componentes do parênquima testicular, comprimento total dos túbulos seminíferos, comprimento de túbulo seminífero por grama de testículo, índices leydigossomático e tubulossomático. Os dados foram avaliados quanto à normalidade pelo teste t de Student, os dados com distribuição normal foram analisados por análise de variância com 5% de probabilidade e os não paramétricos, pelo teste de Kruskal-Wallis, a 5% de probabilidade. Houve diferenças significativas (p<0,05) para índice gonadossomático (G1=0,48±0,08 e G2=0,34±0,09) e altura do epitélio germinativo (G1=52,95±2,99 e G2=47,63±2,67) entre os tratamentos. O feno de catingueira promoveu aumento no peso corporal e consequentemente maior peso testicular, o que contribui para elevação do IGS. Concluiu-se que o consumo da C. pyramidale não possui efeito tóxico sobre os parâmetros testiculares, seminais e histológicos do testículo dos caprinos e que a planta, por suas características nutricionais promoveu melhora no desenvolvimento corporal dos animais e por ser uma planta adaptada ao clima do semiárido, se constitui uma fonte alternativa de alimentação para esta categoria animal, durante períodos de escassez de alimento.(AU)

Resumo: ANTECEDENTES: En el semen, algunos microorganismos pueden encontrar las condiciones óptimas para sobrevivir, ocasionando daños a los espermatozoides y desencadenando procesos de infertilidad o infecciones del tracto reproductivo. Entender el papel de los microorganismos aislados en el semen, contribuye a mejorar el diagnóstico de casos de infertilidad donde la única causa aparente son los procesos infecciosos. OBJETIVO: Describir y correlacionar los parámetros seminales y el crecimiento bacteriano del eyaculado. MÉTODOS: Identificación de los microorganismos aislados en 43 espermocultivos-clínicos y 28 espermocultivos-investigación. Se realizó conteo de las unidades formadoras de colonia a los espermocultivos-investigación y análisis de las características espermáticas. Resultados: Se obtuvo crecimiento bacteriano en 14 (32,6%) de los espermocultivos-clínicos y 15 (53,6%) de los espermocultivos-investigación. Los microorganismos aislados fueron Enterococcus faecalis, Escherichia coli, Morganella morganii, Staphylococcus spp coagulasa negativo, Klebsiella pneumoniae y microbiota mixta. En este estudio se observó abundante crecimiento de cocos aerobios. Finalmente, no se encontró asociación entre la disminución en la calidad de los parámetros seminales y los microorganismos. CONCLUSIONES: La presencia de bacterias en el semen no afecta la calidad seminal.

BACKKGROUND: Microorganisms can find the optimal conditions for survival in semen, causing damage to the spermatozoa and triggering processes of infertility or reproductive tract infections. Therefore, understanding the role of the microorganisms present in semen can help to improve the diagnosis of infertility cases where the only apparent cause is infectious processes. OBJECTIVE: To describe and correlate semen parameters and bacterial growth in ejaculate. METHODS: Identification of microorganisms isolated in 43 clinical spermocultures and 28 research spermocultures. We assessed colony-forming unit counts and sperm characteristics of research spermocultures. In addition, semen parameters were evaluated in each ejaculate. RESULTS: Bacterial growth was obtained in 14 (32.6%) of the 43 clinical spermocultures and 15 (53.6%) of the 28 research spermocultures. The isolated microorganisms were Enterococcus faecalis, Escherichia coli, Morganella morganii, Staphylococcus coagulase negative, Klebsiella pneumoniae and mixed microbiota. Finally, in this study a large growth of aerobic cocci was observed. We did not find association between the decline in the quality of semen parameters and microorganisms. CONCLUSION: The presence of bacteria in semen does not affect semen quality.
