ABSTRACT

Male reproductive health depends on many factors, including whether infectious diseases occur in the reproductive system. Such changes may be reflected in the semen analysis. In the past three years, the number of individuals who fell ill with COVID-19 caused by SARS-CoV-2 has been growing worldwide, including in Russia. This infection causes dysfunction and a negative effect on many organs and systems, including reproductive organs, which is reflected in abnormal semen parameters. Despite the high efficacy and small number of side effects found in clinical trials, only 56% of the population in the US and 49% in the Russian Federation reported wanting the vaccine. One of the reasons for distrust of vaccines is the potential negative impact on fertility. A literature review is devoted to the study of the effect of SARS-CoV-2 and vaccination on male reproductive health. The search was carried out using Medline, PubMed, and EMBASE databases.Copyright © 2023 Authors. All rights reserved.

ABSTRACT

Objective: To determine the impact of Covid-19 vaccines on sperm quality. Study Design: Case control study Place and Duration of Study: Department of Diabetes & Endocrinology, Chandka Medical College Hospital Larkana from 1st July 2022 to 31st December 2022. Methodology: Patients were enrolled as 50 those who had PCR confirmed Covid 19 history and 50 those who never got Covid-19. On this basis those cases who had a Covid-19 history were placed in group A while those who did not had Covid-19 history were placed in Group B. Patients clinical history including anamnesis, marital status, cryptorchidism, operative varicocele, or any chronic ailment were documented. A counting chamber was used for sperm count in a 100 square area. Spermatozoa was measured as either rapid-progressively motile (Type a), or as slow-progressively-motile (Type b), or as situ motile (Type c), and finally as immobile (Type d). The total semen sperm count was gained by multiplication of concentration of sperm with its volume. Result(s): Volume and concentration was significantly different in both study groups. Difference in tail anomaly was also observed. In group A, it was 29.20 +/- 10.26 while 27.59 +/- 12.31 was the value of group B. Almost equal number of participants were married. Azoospermia was only found among Covid patients. Conclusion(s): Azoospermia was only found in Covid patients and no such results were obtained from Covid negative patients.Copyright © 2023 Lahore Medical And Dental College. All rights reserved.

ABSTRACT

So far there has been no comprehensive review using systematic literature search strategies to show the application of single-cell RNA sequencing (scRNA-seq) in the human testis of the whole life cycle (from embryos to aging males). Here, we summarized the application of scRNA-seq analyses on various human testicular biological samples. A systematic search was conducted in PubMed and Gene Expression Omnibus (GEO), focusing on English researches published after 2009. Articles related to GEO data-series were also retrieved in PubMed or BioRxiv. 81 full-length studies were finally included in the review. ScRNA-seq has been widely used on different human testicular samples with various library strategies, and new cell subtypes such as State 0 spermatogonial stem cells (SSC) and stage_a/b/c Sertoli cells (SC) were identified. For the development of normal testes, scRNA-seq-based evidence showed dynamic transcriptional changes of both germ cells and somatic cells from embryos to adults. And dysregulated metabolic signaling or hedgehog signaling were revealed by scRNA-seq in aged SC or Leydig cells (LC), respectively. For infertile males, scRNA-seq studies revealed profound changes of testes, such as the increased proportion of immature SC/LC of Klinefelter syndrome, the somatic immaturity and altered germline autophagy of patients with non-obstructive azoospermia, and the repressed differentiation of SSC in trans-females receiving testosterone inhibition therapy. Besides, the re-analyzing of public scRNA-seq data made further discoveries such as the potential vulnerability of testicular SARS-CoV-2 infection, and both evolutionary conservatism and divergence among species. ScRNA-seq analyses would unveil mechanisms of testes' development and changes so as to help developing novel treatments for male infertility.

ABSTRACT

Bacterial or viral infections, such as Brucella, mumps virus, herpes simplex virus, and Zika virus, destroy immune homeostasis of the testes, leading to spermatogenesis disorder and infertility. Of note, recent research shows that SARS-CoV-2 can infect male gonads and destroy Sertoli and Leydig cells, leading to male reproductive dysfunction. Due to the many side effects associated with antibiotic therapy, finding alternative treatments for inflammatory injury remains critical. Here, we found that Dmrt1 plays an important role in regulating testicular immune homeostasis. Knockdown of Dmrt1 in male mice inhibited spermatogenesis with a broad inflammatory response in seminiferous tubules and led to the loss of spermatogenic epithelial cells. Chromatin immunoprecipitation sequencing (ChIP-seq) and RNA sequencing (RNA-seq) revealed that Dmrt1 positively regulated the expression of Spry1, an inhibitory protein of the receptor tyrosine kinase (RTK) signaling pathway. Furthermore, immunoprecipitation-mass spectrometry (IP-MS) and co-immunoprecipitation (Co-IP) analysis indicated that SPRY1 binds to nuclear factor kappa B1 (NF-κB1) to prevent nuclear translocation of p65, inhibit activation of NF-κB signaling, prevent excessive inflammatory reaction in the testis, and protect the integrity of the blood-testis barrier. In view of this newly identified Dmrt1- Spry1-NF-κB axis mechanism in the regulation of testicular immune homeostasis, our study opens new avenues for the prevention and treatment of male reproductive diseases in humans and livestock.

ABSTRACT

Background: Evidence reveals that COVID-19, in addition to impacting the respiratory system, affects other organs, including the male and female reproductive systems. The purpose of this study was to examine the impact of COVID-19 on the human reproductive system. Method(s): Data were collected in SID, Science Direct, PubMed, and Google Scholar databases. The Keywords including COVID- 19, reproductive system, fertility, and factors related to mesh term utilization and Boolean strategy were used. Papers from 2019 to 2022 were extracted. Finally, out of 58 searched articles, 20 articles related to the purpose of the study were reviewed. Result(s): The results were organized into two categories. The first category deals with the effect of COVID-19 on the female reproductive system including Sleep disorders following quarantine on gonadotropin release and its effect on the ovaries and menstrual cycle, preterm delivery, increased cesarean delivery, the possibility of intrauterine infection of the fetus and dysfunction of the reproductive glands. The second category concerns the effect of COVID-19 on the male reproductive system including abnormal semen quality, possible effect on gonocyte differentiation in the early stages of spermatogenesis, negative effect on spermatogenesis, testicular dysfunction, and changes in testosterone concentration by increasing serum LH, testicular inflammation, decreased sperm concentration in semen, impaired sperm motility, dysfunction of the reproductive glands, significant damage to the seminiferous tube, swelling of Sertoli cells, decreased Leydig cells, significant disorder on semen volume and impaired sperm morphology. Conclusion(s): The findings revealed that COVID-19 has an impact on various aspects of the human reproductive system. Midwives and gynecologists should alleviate couples' fears about infertility by recognizing these cases and offering suitable counseling to couples infected with COVID-19.

ABSTRACT

As the critical risk of the short-term SARS-CoV-2 infection is severe lung inflammation with a hypercoagulative state that could escalate to multiorgan failure, many possible long-term implications are still under investigation. This article will review the most recent findings related to the potential contribution of SARS-CoV-2 to male infertility. Viral-induced male infertility has been studied widely and in much detail in the past. Numerous viral infections have a well-known ability to induce orchitis, resulting in impaired testicular functions and male infertility. SARS-CoV-2 may be an additional virus that is related to male infertility for several reasons that will be dealt with in this review: [1] the strong affinity of SARS-CoV-2 for the human ACE2 receptor, [2] SARS-CoV-2 induced sex steroid hormonal abnormalities, [3] increased levels of oxidative stress in COVID-19, and [4] molecular mimicry between humans and components of SARS-CoV-2 leading to antigenic cross-reactivity phenomena. As these mechanisms might be responsible for SARS-CoV-2-induced male infertility, new evidence demonstrates testicular damage and semen abnormalities following the viral infection. Pathological findings of patients who died of COVID-19 exhibit injury to Sertoli cells and seminiferous tubules with a reduction in Leydig cells, which all are critical components of spermatogenesis. Moreover, impairment of sperm quality was found in SARS-CoV-2-infected patients. Those manifestations found in COVID-19-ill patients, parallel to sex steroid hormonal abnormalities, might critically influence spermatogenesis and SARS-CoV-2-induced male infertility. © 2023 Elsevier Inc.

ABSTRACT

Background: Although Coronavirus Disease 2019 mainly affects the pulmonary system, the related studies on male reproductive health are limited. We aimed to investigate the effect of COVID-19 disease in spermiogram parameters of patients with male infertility. Material and Methods: 39 outpatients with male infertility diagnosed with COVID-19 disease between 1st March 2020 and 31st March 2022 in our andrology policlinic were analysed, retropspectively. We evaluated the demographic data of the patients and the spermiogram analyzes before and after the COVID-19 disease. Results: The mean age of the patients were 33,44±7,52 years and body mass index (BMI) was 27,05±3,38 kg/m2. The mean time between PCR test and second semen analysis was 3,95±3,59 months. There were statistically significant reduction in semen volüme (p<0,03) and significant deterioration in sperm morphology (p<0,014), but no detect alteration on sperm motility. Conclusion: We observed adversly effects of SARS-CoV-2 virus on spermiogram parameters in patients with male infertility. Deterioration of spermiogram after COVID-19 disease may results with male infertility. (English) [ FROM AUTHOR] Amaç: Koronavirus hastalığı 2019 (COVID-19) esas olarak pulmoner sistemi etkilemesine rağmen, erkek üreme sağlığı üzerine çalışmalar sınırlıdır. Bizim kliniğimize erkek infertilitesi ile başvuran hastalarda COVID-19 hastalığının (virusunun) sperm parametrelerine etkisini araştırmayı amaçladık. Gereç ve Yöntem: Bizim androloji kliniğimize 1 Mart 2020 ve 31 Mart 2022 tarihleri arasında başvuran ve daha öncesinde COVID-19 hastalığı tanısı almış 39 erkek infertilite hastası retrospektif olarak analiz edildi. Hastaların demografik verileri, COVID-19 hastalığı öncesi ve sonrası spermiogramları değerlendirildi. Bu verileri kaydettik ve istatistiksel olarak karşılaştırdık. Bulgular: Hastaların ortalama yaşı 33,44±7,52 yıl ve vücut kitle indeksi (BMI) 27,05±3,38 kg/m2 olarak saptandı. PCR testi ile ikinci semen analizi arasındaki ortalama süre 3,95±3,59 ay olarak ölçüldü. Semen morfolojinde(p< 0,014) önemli bozulma ve semen volümünde (p<0,03) önemli azalma istatiksel olarak gözlememize rağmen sperm motilitesi açısından anlamlı farklılık saptanmadı. Sonuç: Erkek infertilite hastalarında spermiogram parametreleri üzerine SARS-CoV-2 virüsünün olumsuz etkisi olduğunu gözlemledik. COVID- 19 hastalığından sonra spermiogramdaki bozulma erkek infertilitesi ile sonuçlanabilir.

ABSTRACT

BACKGROUND: Cellular entry of SARS-CoV-2 has been shown to rely on angiotensin-converting enzyme 2 (ACE2) receptors, whose expression in the testis is among the highest in the body. Additionally, the risk of mortality seems higher among male COVID-19 patients, and though much has been published since the first cases of COVID-19, there remain unanswered questions regarding SARS-CoV-2 impact on testes and potential consequences for reproductive health. We investigated testicular alterations in non-vaccinated deceased COVID-19-patients, the precise location of the virus, its replicative activity, and the immune, vascular, and molecular fluctuations involved in the pathogenesis. RESULTS: We found that SARS-CoV-2 testicular tropism is higher than previously thought and that reliable viral detection in the testis requires sensitive nanosensors or RT-qPCR using a specific methodology. Through an in vitro experiment exposing VERO cells to testicular macerates, we observed viral content in all samples, and the subgenomic RNA's presence reinforced the replicative activity of SARS-CoV-2 in testes of the severe COVID-19 patients. The cellular structures and viral particles, observed by transmission electron microscopy, indicated that macrophages and spermatogonial cells are the main SARS-CoV-2 lodging sites, where new virions form inside the endoplasmic reticulum Golgi intermediate complex. Moreover, we showed infiltrative infected monocytes migrating into the testicular parenchyma. SARS-CoV-2 maintains its replicative and infective abilities long after the patient's infection. Further, we demonstrated high levels of angiotensin II and activated immune cells in the testes of deceased patients. The infected testes show thickening of the tunica propria, germ cell apoptosis, Sertoli cell barrier loss, evident hemorrhage, angiogenesis, Leydig cell inhibition, inflammation, and fibrosis. CONCLUSIONS: Our findings indicate that high angiotensin II levels and activation of mast cells and macrophages may be critical for testicular pathogenesis. Importantly, our findings suggest that patients who become critically ill may exhibit severe alterations and harbor the active virus in the testes.

ABSTRACT

Introduction: COVID-19 (SARS-CoV-2) has been linked to organ damage in humans since its worldwide outbreak. It can also induce severe sperm damage, according to research conducted at numerous clinical institutions. However, the exact mechanism of damage is still unknown. Methods: In this study, testicular bulk-RNA-seq Data were downloaded from three COVID-19 patients and three uninfected controls from GEO to evaluate the effect of COVID-19 infection on spermatogenesis. Relative expression of each pathway and the correlation between genes or pathways were analyzed by bioinformatic methods. Results: By detecting the relative expression of each pathway and the correlation between genes or pathways, we found that COVID-19 could induce testicular cell senescence through MAPK signaling pathway. Cellular senescence was synergistic with MAPK pathway, which further affected the normal synthesis of cholesterol and androgen, inhibited the normal synthesis of lactate and pyruvate, and ultimately affected spermatogenesis. The medications targeting MAPK signaling pathway, especially MAPK1 and MAPK14, are expected to be effective therapeutic medications for reducing COVID-19 damage to spermatogenesis. Conclusion: These results give us a new understanding of how COVID-19 inhibits spermatogenesis and provide a possible solution to alleviate this damage.

ABSTRACT

PURPOSE: The SARS-CoV-2 pandemic has rapidly spread worldwide and, among the others, the male gender was quickly recognized as an independent risk factor for both the disease and its consequences. Since the possibility of long-term hormonal axis changes and male gamete impairment have been hypothesized but a relatively low levels of evidence has been reached, we focused this narrative mini-review on summarizing key state-of-the-art knowledge on male reproductive effects of COVID-19 as a quick reference for reproductive health specialists. METHODS: A comprehensive Medline/PubMed and Embase search was performed selecting all relevant, peer-reviewed papers in English published from 2020. Other relevant papers were selected from the reference lists. RESULTS: Available evidence indicates that the likelihood of direct testicular damage from SARS-CoV-2 is somewhat low, but there are many indirect ways (fever, cytokine imbalance, and drugs) through which the pituitary-gonadal axis and spermatogenesis may be disrupted. These alterations are probably transient, but as available evidence is low quality, it cannot be excluded that previous pathologies or comorbidities might modulate the risk of their persistence. On the other hand, available evidence shows high safety regarding andrological health for available vaccines, although studies are mainly focused on mRNA vaccines. CONCLUSION: A careful andrological evaluation of men recovering from COVID-19 is highly recommended. Since available evidence is relatively scarce, a careful andrological follow-up and counseling of these patients are mandatory.

ABSTRACT

Background It is well known that some viral infections may affect male fertility. Coronavirus disease (COVID-19) can lead to multiorgan damage through the angiotensin-converting enzyme-2 receptor, abundant in testicular tissue. However, little information is available regarding the shedding of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in semen and its impact on spermatogenesis and fertility potential. We planned to investigate the presence of SARS-CoV-2 in the semen of COVID-19 males and to study the effect of COVID-19 on semen quality and sperm DNA fragmentation index. Material and method Thirty COVID-19 male patients aged 19-45 registered to AIIMS Patna hospital participated in the survey between October 2020 and April 2021. We conducted a real-time reverse transcriptase test on all the semen samples. Detailed semen analysis, including the sperm DNA Fragmentation Index, was done at first sampling that is during COVID-19. After 74 days of the first sampling, we obtained the second sampling and repeated all the above tests. Results All semen samples collected in the first and second sampling tested with real-time reverse transcription-polymerase chain reaction (RT-PCR) were negative for SARS-CoV-2. In the first sampling, semen volume, vitality, total motility, sperm concentration, total sperm count, % normal morphology, % cytoplasmic droplet, and fructose were significantly lower. In contrast, semen agglutination, % head defect, DNA Fragmentation Index, liquefaction time, semen viscosity, and leukocytes were increased. These findings were reversed at the second sampling but not to the optimum level. All these findings were statistically significant (p < 0.05 for all). Thus, COVID-19 negatively affects semen parameters, including sperm DNA fragmentation index. Conclusion Although we could not find SARS-CoV-2 in the semen, the semen quality remained poor until the second sampling. Assisted reproductive technology (ART) clinics and sperm banking facilities should consider assessing the semen of COVID-19 males and exclude men with a positive history of SARS-CoV-2 until their semen quality returns to normal.

ABSTRACT

Blood-testis barrier is body's innate mechanism to defend germ cells by creating a physical and immunological barrier. But some viral infections are known to evade it. As ACE2 and TMPRSS2 are present all over the body including male reproductive tract, it is worth exploring how coronavirus disease (COVID-19) could possibly affect male fertility. A review of literature was done using search engines like PubMed, Medline, Google Scholar, etc., and all the latest articles up to May 2021 were considered. Some studies have substantiated the presence of orchitis in COVID patients using semen and tissue samples. Though most studies report the absence of virus in testis, involvement of seminiferous tubules has been seen in pathological analysis suggesting defective spermatogenesis. This can be primarily attributed to inflammation and increased vascular permeability. Other factors that could affect male fertility are fever, autoimmune response, drugs, and erectile dysfunction. Male fertility is an important aspect of health care and must be looked into. Further studies can be done to understand host immunity towards SARS-CoV-2 in the testis. It will be worthwhile to know whether viral orchitis and its sequelae are acute or chronic in nature, and if they are reversible. Effect of the virus on female reproductive tract can also be assessed further. Counselling can be given to affected/recovering patients along with correct selection of drugs to prevent these long-term complications.

ABSTRACT

Since the end of 2019, the world has been overwhelmed by a pandemic of a new coronavirus infection (COVID-19), a disease that damages various organs and systems. Because of the extensive coverage of the population by the infection, the long-term effects of the disease are not well understood, which is of considerable scientific and practical interest. We performed an in-depth analysis and systematization of data from foreign and domestic publications in the Scopus, Web of Science, eLIBRARY, PubMed, Wiley Online Library, and Google Scholar databases were performed. Information searches included original articles, reviews, guidelines, manual comments, and editorials related to the effects of SARS-CoV-2 virus on the male reproductive system. Accumulated clinical evidence suggests that the SARS-CoV-2 virus and the COVID-19 disease it causes have a negative impact on male reproductive health.. Drugs with a negative effect on spermatogenesis are used in the therapy of patients with COVID-19. These include lopinavir, chloroquine and its derivatives, and widely used glucocorticosteroids. Lopinavir and chloroquine have subsequently been excluded from potential COVID-19 therapy. Although available data on the fertility of men with COVID-19 are scarce and the results of published studies are from a limited sample, it is clear that maintaining male reproductive health during the COVID-19 pandemic is a pressing issue in modern medicine and requires further in-depth study. Preconceptional screening should be recommended for men who have undergone COVID-19.
