Abstract
BACKGROUND In the medical field, it is increasingly common to observe the use of nanotubes, for example, in the administration of drugs. However, nanotubes raise concerns for male fertility due to potential effects on hormone levels and sperm quality observed in animal studies. In addition, animal exposure to multi-walled carbon nanotube models found alterations in hormone levels, sperm motility, and sperm count. Limited evidence in humans suggests no adverse effects, but further research is needed. This study aimed to perform a systematic review to assess the in vitro effects of nanotubes on semen and fertility in humans. METHODS We included all published in vitro studies about semen or sperm or male fertility and nanotubes in humans. A search was conducted in LILACS, PubMed, and SCOPUS as of May 2023. The risk of bias was assessed using the QUIN tool. RESULTS Four studies using nanotubes on human sperm were included, nanotubes exposure appears not to affect sperm viability; however, some alterations to motility, velocity and production of reactive oxygen species were reported. Limited evidence is provided because of the small quantity of publications. CONCLUSIONS Nanotubes appear to have no adverse effects on human sperm.

Abstract
Recently, a study reported that upon analyzing blood samples from 14 astronauts that flew Space Transportation System missions between 1998 and 2001, 34 somatic nonsynonymous single nucleotide variants were detected in 17 CH-driver genes. Of interest is that the cohort consisted of relatively young astronauts, 85% of which were males of reproductive age. Having investigated the genes with nonsynonymous substitutes from the literature, it was found that twelve of these 17 genes appear to play essential roles in male reproduction. Changes in telomere length and gene regulation were also reported in another study conducted on an astronaut during a long duration stay on the International Space Station. Realizing the impact of spaceflight on gene sequence with potential influence on male fertility, it is important that more studies are conducted in this field. Specifically, in light of ultimately colonizing space, multi-generational survival is crucial and strategies to mitigate or counteract such effects should be explored.

Abstract
The objective of this work was to determine the frequency of bacteriospermia and its effect on the seminal quality in canines. Dogs were divided into two groups according to weight: small dogs between 1 and 10 kg (Group 1) and dogs with more than 10 kg (Group 2). The foreskin was disinfected in each animal (n=15), and the semen sample was collected by the gloved hand method. Sperm motility, morphology, viability, and concentration were evaluated using a 40x microscope. A 10µL of semen drop was cultured by diffusion method on blood agar and MacConkey agar. Colony-forming units (CFU) were quantitatively evaluated, and biochemical identification was carried out after 48 hours at 37°C. Conventional PCR was performed on the semen samples to evaluate the presence/absence of 11 bacteria. Bacterial growth was found in all samples. The CFU/mL in blood agar were 34042.8 for group 1 and 107714.3 for group 2, while on MacConkey agar were 142.9 CFU/mL, and 21328.6 CFU/mL, respectively. Coagulase-negative Staphylococcus was the most frequent bacteria isolated by conventional culture (64.3%), and Staphylococcus aureus and Klebsiella spp. were the most common bacteria found by conventional PCR. Between both groups, only a statistically significant difference was found in normal sperm morphology. A negative correlation was observed between viability and morphology with CFU on MacConkey agar. One dog was ruled out because he had azoospermia. Canine seminal bacteriospermia is quite frequent and could alter its quality. The presence of Gram-negative bacteria is associated with greater alteration in the semen analysis.

Abstract
For the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, clinical manifestations are broad and highly heterogeneous for both sexes. We aimed to determine how biological sex and age impact immune gene expression, particularly influencing the humoral neutralizing antibody (NAb) response and the cytokine production in coronavirus disease 2019 (COVID-19) subjects. The immune gene expression, according to biological sex and age, was assessed using the genome wide expression profile of blood proteins from healthy individuals using the Genotype Tissue Expression (GTEx) database. Moreover, anti-SARS-CoV-2 neutralizing antibody titers and cytokine levels were determined in blood samples from 141 COVID-19 individuals from Medellín, Colombia. Among subjects with COVID-19, males had statistically significantly higher median NAb titers and serum concentrations of interleukin-6 and CC chemokine ligand 3 than females. Overall, our findings point out a more robust innate immune response in women that could help recognize and restrain the virus faster than in men.

Abstract
ResumenLa evidencia sugiere que la exposición a sustancias psicoactivas se relaciona con alteraciones en la espermatogénesis que afectan la calidad espermática. El objetivo de este trabajo fue determinar los parámetros espermáticos en consumidores habituales de cigarrillos de marihuana. Se analizaron muestras seminales de 42 consumidores activos de cigarrillos de marihuana y de 16 voluntarios no consumidores de marihuana. Mediante un análisis de semen, se determinaron los parámetros seminales convencionales (viabilidad, movilidad, morfología, y concentración de los espermatozoides) siguiendo los lineamientos establecidos por la Organización Mundial de la Salud (OMS). Adicionalmente, se evaluó la capacidad antioxidante del plasma seminal mediante la determinación del porcentaje de inhibición del radical estable 1,1-difenil-2-picril-hidracilo. Los valores de la mediana de los consumidores respecto al grupo control fueron: volumen – 2,98 mL versus 3,95 mL (p = 0,0221); concentración total – 189 millones/mL versus 291,1 millones/mL (p = 0,0636); movilidad progresiva – 50% versus 56,5% (p = 0,0052); viabilidad – 65,3% versus 73,1% (p = 0,0732); y morfología normal – 5% versus 7% (p = 0,0167), respectivamente. Los resultados obtenidos en este estudio indican que el consumo de cigarrillos de marihuana afecta negativamente la movilidad progresiva, la morfología normal y la concentración total de espermatozoides; además, la concentración total de espermatozoides está afectada por la frecuencia del consumo de cigarrillos de marihuana.

Abstract
The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on male infertility has lately received significant attention. SARS-CoV-2, the virus that causes coronavirus disease (COVID-19) in humans, has been shown to impose adverse effects on both the structural components and function of the testis, which potentially impact spermatogenesis. These adverse effects are partially explained by fever, systemic inflammation, oxidative stress, and an increased immune response leading to impaired blood-testis barrier. It has been well established that efficient cellular communication via gap junctions or functional channels is required for tissue homeostasis. Connexins and pannexins are two protein families that mediate autocrine and paracrine signaling between the cells and the extracellular environment. These channel-forming proteins have been shown to play a role in coordinating cellular communication in the testis and epididymis. Despite their role in maintaining a proper male reproductive milieu, their function is disrupted under pathological conditions. The involvement of these channels has been well documented in several physiological and pathological conditions and their designated function in infectious diseases. However, their role in COVID-19 and their meaningful contribution to male infertility remains to be elucidated. Therefore, this review highlights the multivariate pathophysiological mechanisms of SARS-CoV-2 involvement in male reproduction. It also aims to shed light on the role of connexin and pannexin channels in disease progression, emphasizing their unexplored role and regulation of SARS-CoV-2 pathophysiology. Finally, we hypothesize the possible involvement of connexins and pannexins in SARS-CoV-2 inducing male infertility to assist future research ideas targeting therapeutic approaches.

Abstract
Chronic prostatitis is a widespread disease of the prostate affecting men’s sexual and reproductive health worldwide. Its leading causes are urogenital tract infections by microorganisms with a prostate tropism. This study aimed to evaluate semen parameters and the factors associated (lifestyle, urogenital infections, and inflammation) with the onset of chronic prostatitis symptoms. This case-control study included seventy-six donors: 30 volunteers with chronic prostatitis and 46 asymptomatic volunteers for urogenital infections as a control group. Sociodemographic, urinary symptoms, pain location, sexual and reproductive health and lifestyle-related variables were collected in a survey. Seminal quality, cytokine levels in semen and serum, and the presence of nineteen microorganisms in the urogenital tract were evaluated. Prostatitis was also associated with poor sperm morphology, more lipoperoxidation of the sperm membrane, and lower serum nitric oxide concentration. In addition, N. gonorrhoeae infection was detected more frequently in semen samples from volunteers with chronic prostatitis. Volunteers with chronic prostatitis report more frequently erectile dysfunction and premature ejaculation, anxiety, depression, and stress compared to the control group. Chronic prostate infections alter the microbiota from the genitourinary tract causing prostatitis, a disease that affects all life areas, including the familiar environment of patients. Chronic prostatitis affects seminal parameters, with a great impact on life quality and sexual and reproductive health. Despite being a relatively unexplored disease, much remains to be clarified regarding its diagnosis and treatment. Alterations in the genitourinary microbiota can favor sexually transmitted infections that produce chronic and systemic inflammation.

Abstract
Background: Male infertility is associated with altered characteristics of the sperm within the ejaculate. It is possible to find molecular explanations for the observed phenotypes and their consequences. This study aimed to analyze, using a specialized software, a gene set of transcriptomic data from different types of ejaculates. Methods: Data from ejaculate samples categorized as normal, oligospermia, and teratozoospermia were obtained from Gene Expression Omnibus (GEO). After normalization, the data average for each sample category was calculated and analyzed independently using Ingenuity Pathway Analysis (IPA). Results: Five important canonical pathways are involved in normal and altered semen samples (Oligospermia and teratozoospermia) except sirtuin signaling and mitochondrial dysfunction pathways. The five most important biological processes are identified in all semen phenotypes, but the only difference is the genes connected with initiation of RNA transcription in oligospermic and asthenospermic samples. Conclusion: Surprisingly, different types of ejaculates share many pathways and biological processes; sperm proteomics as a new global approach gives clues for the development of strategies to explain the reason for observed phenotypes of ejaculated spermatozoa, their possible effect on fertility, and for implementing research strategies in the context of infertility diagnosis and treatment.

Abstract
Abstract
Introduction Glyphosate is an herbicide used to eradicate illicit crops; however, its use is controversial due to different health problems associated with it. The present study aims to evaluate the effects of glyphosate on human sperm in vitro.
Methods Twenty-two semen samples from healthy normozoospermic men were included; 11 semen samples were incubated with Panzer (INVESA S.A., Antiquia, Colombia) and 11 with Roundup (Monsanto Company, MO, USA). The changes in motility and viability were observed. Functional seminal parameters were evaluated as well.
Results The samples exposed to glyphosate showed less motility and viability; a decrease in the potential of the mitochondrial membrane was observed, and an increase in the lipoperoxidation of the membrane was evidenced.
Conclusion Based on the present results, we concluded that glyphosate has cytotoxic potential for exposed people and may affect their fertility.

Objective To detect DNA of different microorganisms, in semen samples from apparently healthy men and correlate their presence with seminal quality. Methods Semen samples from 81 healthy volunteers were collected, and semen parameters were analyzed. DNA extraction was performed using the phenol-chloroform technique, and the microorganisms were detected by the amplification of specific primers using polymerase chain reaction. Results DNA from at least one of the microorganisms was detected in 78 samples. The most frequent microorganism found in semen were: Lactobacillus spp. (70%), Neisseria gonorrhoeae (N. gonorrhoeae) (36%), Streptococcus epidermidis (64%), Klebsiella pneumoniae (56%), Staphylococcus aureus (32%), Chlamydia trachomatis (C. trachomatis) (28%), Pseudomonas aeruginosa (27%). The seminal parameters of all semen samples were over the lower reference values for normal semen analysis. To compare with negative samples, seminal volume was higher for the Escherichia coli positive samples and lower for Pseudomonas aeruginosa positive samples. Semen samples positive for Staphylococcus aureus had worse sperm morphology. The frequency of progressive motility was higher in positive samples for N. gonorrhoeae and C. trachomatis. Positive semen samples for C. trachomatis had a higher concentration per milliliter. Conclusion It is common to find microorganisms in semen of asymptomatic men, including those responsible for sexually transmitted infections. Antimicrobial treatment is recommended only in those individuals with a sexually transmitted infection (C. trachomatis and N. gonorrhoeae) and always promote condom use.

Abstract
ResumenDurante las relaciones sexuales, se da el intercambio de especies bacterianas entre las parejas, siendo las relaciones sexuales un factor crucial en la modificación de la microbiota genital. En el presente artículo de reflexión, se analizó el efecto de las relaciones sexuales sobre el intercambio de la microbiota vaginal y seminal. Las parejas que sostienen relaciones sexuales sin protección comparten especies bacterianas que podrían influir negativamente o positivamente sobre los parámetros seminales, como los Lactobacillus con potencial probiótico para el mantenimiento de la calidad del semen.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-COV-2), a single-stranded RNA virus, was found to be the causal agent of the disease called coronavirus disease. During December 2019, China informed the World Health Organization (WHO) of an outbreak of cases of pneumonia of unknown etiology, which caused severe-acute respiratory distress. The disease was termed coronavirus disease 2019 (Covid-19). Due to alarming levels of spread and severity, on the 11th of March 2020, the WHO declared the outbreak as a global pandemic. As of September 14, 2020, more than 29 million cases have been reported, with over 900,000 deaths globally. Since the outbreak, although not conclusive, discoveries have been made regarding the understanding of the epidemiology, etiology, clinical features, clinical treatment, and prevention of the disease. SARS-COV-2 has been detected in saliva, respiratory fluids, blood, urine, and faeces. Findings are however controversial regarding its presence in the semen or the testis. Hence, this review aimed to further analyse the literature concerning (i) the effects of previously identified human coronaviruses on male fertility (ii) the impact of Covid-19 on male fertility and (iii) the implication for general health in terms of infection and transmission.

Abstract
Prostatitis and premature ejaculation are urological problems that impact sexual and reproductive health in males frequently. The aim of this narrative review is to provide an overview of the relationship between premature ejaculation and prostatitis. A narrative review literature was performed in the PubMed and SCOPUS databases. The most relevant aspects of the etiology of premature ejaculation were detailed, and the causal relationship between prostatitis and premature ejaculation was explored. Treatment should consider the pathophysiology and diagnosis; this is a significant challenge for the urologist. A total of 45 original articles were compiled in a table within the main findings. Both alterations are associated with a decrease in the quality of life and have a negative impact on the couple's relationship. The timely treatment offers improvement or complete recovery for the patients.

Abstract
The worldwide spread of the emerging respiratory disease produced by SARS-CoV-2 has become a matter of great concern to public health. The expression of the viral receptor ACE2 in the male reproductive tract arises hypothesis about a possible targeting to testicular tissue during the infection and further implications to male fertility. However, current data of whether the virus is present or not in the seminal fluid is contrasting. Objectives: The propose of this opinion article was to describe the impact SARS-CoV-2 infection in males. We analyze SARS-CoV-2 infection and the sex differential epidemiological impact in 3 185 468 cases from 53 countries. Although men and women seem equally susceptible to infection, SARS-CoV-2 elicits worsening outcomes in males; the mean proportion of deaths in confirmed cases (male:female ratio) is 1.5 (95% CI: 1.39 – 1.62). To date, evidence shows that the stronger inflammatory response in men is a marker of disease severity and mortality, and systemic inflammation might be correlated to the altered hormone profile in male patients. More high-quality information regarding the pathophysiology of the infection and gender disparity is needed to understand the higher mortality rates in men.

Abstract
While we are waiting for the “best good news” of a vaccine that allows us to control the SARS-CoV-2 virus that causes COVID-19, we have to find a solution to reduce the adverse effects of the disease on people’s health. The situation is not hopeful. According to the World Health Organization, 4278180 people have been infected, of whom 292376 have died (May 13, 2020), many in their productive age who surely were out of the economic upheavals due to the measures adopted to anticipating the pandemic will also have a negative impact on the world economy.

Abstract
Since the start of the latest coronavirus (SARS-CoV-2) outbreak, the number of infected individuals and cases of coronavirus disease (COVID-19) has been increasing exponentially worldwide. Of interest is existing evidence that orchitis can develop due coronavirus infection. It is therefore not unreasonable to believe that SARS-CoV-2 could be transmitted by semen. Consequently, it is of paramount importance that individuals who could potentially be infected take all possible care to mitigate the likely risk of passing on the infection through sexual intercourse.

Abstract
Resumen
Introducción Los cigarrillos electrónicos (E-Cig) aparecieron en el mercado hace 15 años como una alternativa para combatir el consumo de tabaco, un problema de salud pública, sin embargo, su efecto sobre la salud reproductiva no ha sido completamente evaluado. El objetivo del presente estudio, fue evaluar los efectos de los E-Cig sobre los espermatozoides humanos in vitro.
Métodos Un dispositivo para incubar en contacto directo a los espermatozoides con el vapor a partir de dos esencias diferentes (TNT y Sugar Drizzle), el humo del cigarrillo o aire como control negativo fue construido. Adicionalmente, usando el mismo dispositivo, se elaboró el extracto a partir del aire, de las dos esencias con el E-Cig y con el cigarrillo Piel Roja sin filtro en medio para incubar en contacto indirecto con los espermatozoides.
Resultados Se observó disminución de la movilidad con el E-Cig en más del 38% en el tiempo y una disminución de la viabilidad en más del 18% que se mantenían con el tiempo mientras que con el cigarrillo convencional afectaba la movilidad y la viabilidad en casi el 100%. Finalmente se encontró que se afecta más la movilidad de los espermatozoides con la esencia de Sugar Drizzle que contaba con menos concentración de nicotina que con la esencia de TNT.
Conclusiones En conclusión, tanto el cigarrillo convencional como el E-Cig afectan los parámetros seminales (movilidad y viabilidad), y se postula que el uso del E-Cig, aunque es menos citotóxico y afecta menos que el cigarrillo convencional, también puede generar a largo plazo problemas de infertilidad.

Abstract
ResumenEn los últimos años, se ha reportado en la literatura científica un declive en la calidad seminal. La significancia biológica de ese evento podría estar relacionada con la reducción en la fertilidad masculina o con el aumento del riesgo de enfermedades en la descendencia. La occidentalización en el estilo de vida, caracterizado por el aumento del peso corporal, el sedentarismo, el uso de cigarrillo, la ingesta de alimentos ricos en grasas y sodio y la reducción en la ingesta de alimentos fuente de fibras y antioxidantes, pudieran estar implicados en esos resultados. A su vez, cambios en el estilo de vida, que conduzcan a una reducción de peso corporal, de la ingesta de grasa y sodio, a un mejor estado antioxidante y a un aumento de la ingesta de fibra, se han asociado a mejores parámetros seminales. Por lo tanto, la alimentación basada en plantas o vegetariana, podría ser una estrategia válida para mejorar el estado nutricional y la salud masculina.

Abstract
ResumenDeterminar el efecto del glifosato sobre la calidad seminal en humanos a través de una revisión sistemática. Se realizó una búsqueda de la literatura en dos bases de datos (Pubmed y Scopus) de los terminos glyphosate/gliphosate/Roundup/yerbimat y sperm/“male reproductive tract”. Los criterios de selección permitieron analizar tres artículos sobre el efecto del glifosato sobre los espermatoozides humanos. Se observó un efecto de negativo del glifosato sobre los espermatoozides humanos (movilidad, actividad mitocondrial y DNA). Aunque son pocos los artículos que evalúan el efecto del glifosfato sobre la calidad seminal, todos concluyen en sus repercusiones negativas. Investigaciones sobre el tema se requieren especialmente ahora que el Gobierno Nacional pretende implementar su uso.

Abstract
Objetivo El objetivo de este trabajo es determinar el efecto in vitro de los suplementos vitamínicos que se venden como afrodisíacos sobre la movilidad espermática.
Materiales y métodos Comprimidos de venta libre obtenidos en diferentes centros de venta de productos naturales y sexuales de la ciudad de Medellín fueron evaluados (Sex Bull, Ses-Max, Vigorday, Up12, Furumbao, Canguro, MAGYMas) y diluidos en solución salina. Posteriormente, fueron mezclados en proporciones iguales con las muestras de semen de 22 voluntarios aparentemente sanos y se determinó el efecto sobre la movilidad en función del tiempo (0, 60, 120 y 180 minutos).
Resultados El análisis del efecto de los tratamientos con extractos acuosos de los suplementos vitamínicos sobre los espermatozoides, fueron divididos según la presencia de L-arginina en su composición. No se observaron cambios positivos sobre la movilidad espermática.
Conclusión Los suplementos vitamínicos que se venden en las tiendas naturistas y sexuales de la ciudad, no ejercen ningún efecto sobre la calidad seminal in vitro, seguramente basados en su composición solo sirven como suplementos energéticos.

Abstract
The 100,000th scientific article on the subject of spermatozoa was recently published. Numerous studies evaluated the
characteristics of this important cell that led to tremendous discoveries. Since its first observation and description in
1677, many important characteristics have been described regarding this highly fascinating gamete. In this review,
we intend to provide a historical account of the numerous milestones and breakthroughs achieved related to sperma-
tozoa. We conducted a review of the literature by selecting the most important subjects with regards to spermatozoa.
Since their discovery by van Leeuwenhoek, spermatozoa have been studied by scientists to better understand their
physiology and process of interaction with their female counterpart, the oocyte, in order to treat and resolve infertility
problems. Three centuries after van Leeuwenhoek’s discovery, the 100,000th article about these cells was published. It
is encouraging that sperm research reached this landmark, but at the same time it is clear that further research on male
reproductive physiology and spermatozoa is required to shed more light on their function and pathology in order to
reduce the number of unexplained infertility cases.

Abstract
Background The quality of semen depends upon several factors such as environment,
life style, physical activity, age, and occupation. The aim of this study was to analyze and
compare the conventional and functional semen parameters in men practicing vigorous
physical activity to those of sedentary men. Materials and Methods In this descriptive cross-sectional study, semen samples of 17
physically active men and 15 sedentary men were collected for analysis. Semen analysis
was performed according to the World Health Organization (WHO) guidelines, while
functional parameters were evaluated by flow cytometry. Results Results showed that several semen parameters (semen volume, viability, progressive motility, total motility, normal morphology, and moribund cells) were superior
in the physically active group in comparison with the sedentary group. Semen parameters
such as viability, progressive motility and total motility, as well as the percentage of moribund spermatozoa were significantly different between both groups. However, sperm
DNA damage, lipid peroxidation and mitochondrial potential were not significantly different among the groups. Conclusion Nevertheless, the physical activity shows better semen parameters than sedentary group. Taken together, our results demonstrate that regular physical activity has
beneficial impact in sperm fertility parameters and such a life style can enhance the fertility status of men.

Abstract
BACKGROUND Several factors have been shown to influence semen parameters, one of which is sexual abstinence; a clinical criteria included in the semen evaluation to provide maximum sperm quality. The aim of the present study was to assess the effect of a daily ejaculation frequency on conventional and functional semen parameters. METHODS Semen samples were collected daily over a period of two weeks of which every second sample per person was processed and analyzed according to the World Health Organization guidelines. Furthermore, mitochondrial function, intracellular reactive oxygen species production and sperm DNA fragmentation were evaluated by flow cytometry. RESULTS Total sperm count and seminal volume per ejaculation declined and remained decreased for the duration of the daily ejaculation period. However, conventional parameters such as sperm concentration, motility, progressive motility, morphology, vitality and functional parameters such as sperm plasma membrane integrity, mitochondrial membrane potential and DNA fragmentation was not significantly affected and remained similar to the initial measurement throughout the daily ejaculation period. Despite intra- and inter individual variations, the average values of the basic semen parameters remained above the WHO (2010) reference values throughout the daily ejaculation period. Interestingly, a decreasing trend in intracellular ROS production was observed, although statistically not significant. CONCLUSIONS The study shows that an extended 2 week period of daily ejaculation does not have major clinical effects on conventional and functional seminal parameters.
