ABSTRACT
Objective To explore the core targets and important pathways of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) induced atherosclerosis (AS) progression from the perspective of immune inflammation, so as to predict the potential prevention and treatment of traditional Chinese medicine (TCM). Methods Microarray data were obtained from the Gene Expression Omnibus (GEO) database for coronavirus disease 2019 (COVID-19) patients and AS patients, and the "limmar" and "Venn" packages were used to screen out the common differentially expressed genes (DEGs) genes in both diseases. The gene ontology (GO) and Kyoto encyclopedia of genes and genomes (KEGG) analyses were performed on the common DEGs to annotate their functions and important pathways. The two gene sets were scored for immune cells and immune function to assess the level of immune cell infiltration. The protein-protein interaction (PPI) network was constructed by STRING database, and the CytoHubba plug-in of Cytoscape was used to identify the hub genes. Two external validation datasets were introduced to validate the hub genes and obtain the core genes. Immuno-infiltration analysis and gene set enrichment analysis (GSEA) were performed on the core genes respectively. Finally the potential TCM regulating the core genes were predicted by Coremine Medical database. Results A total of 7898 genes related to COVID-19, 471 genes related to AS progression;And 51 common DEGs, including 32 highly expressed genes and 19 low expressed genes were obtained. GO and KEGG analysis showed that common DEGs, which were mainly localized in cypermethrin-encapsulated vesicles, platelet alpha particles, phagocytic vesicle membranes and vesicles, were involved in many biological processes such as myeloid differentiation factor 88 (MyD88)-dependent Toll-like receptor signaling pathway transduction, interleukin-8 (IL-8) production and positive regulation, IL-6 production and positive regulation to play a role in regulating nicotinamide adenine dinucleotide phosphate oxidase activity, Toll-like receptor binding and lipopeptide and glycosaminoglycan binding through many biological pathways, including Toll-like receptor signaling pathways, neutrophil extracellular trap formation, complement and coagulation cascade reactions. The results of immune infiltration analysis demonstrated the state of immune microenvironment of COVID-19 and AS. A total of 5 hub genes were obtained after screening, among which Toll-like receptor 2 (TLR2), cluster of differentiation 163 (CD163) and complement C1q subcomponent subunit B (C1QB) genes passed external validation as core genes. The core genes showed strong correlation with immune process and inflammatory response in both immune infiltration analysis and GSEA enrichment analysis. A total of 35 TCMs, including Chuanxiong (Chuanxiong Rhizoma), Taoren (Persicae Semen), Danggui (Angelicae Sinensis Radix), Huangqin (Scutellariae Radix), Pugongying (Taraxaci Herba), Taizishen (Pseudostellariae Radix), Huangjing (Polygonati Rhizoma), could be used as potential therapeutic agents. Conclusion TLR2, CD163 and C1QB were the core molecules of SARS-CoV-2-mediated immune inflammatory response promoting AS progression, and targeting predicted herbs were potential drugs to slow down AS progression in COVID-19 patients.Copyright © 2023 Editorial Office of Chinese Traditional and Herbal Drugs.

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
Objective: To assess whether the coronavirus disease 2019 (COVID-19) mRNA vaccine affects sperm morphokinetics using a computer-assisted semen analyzer and other semen parameters using a sperm chromatin structure assay. Method(s): Healthy male volunteers in two Japanese clinics between May 2021 and December 2021 were prospectively analyzed. Participants donated sperm twice, two days apart, in the following phases: before vaccination, 2 weeks after the first vaccine dose, and 2, 4, and 12 weeks after the second dose. Basic sperm parameters, sperm motility characteristics, and the percentage of DNA-damaged sperm were compared among the different phases. Result(s): Ninety-six semen samples from ten volunteers, who were vaccinated with the BNT162b2 mRNA vaccine, were evaluated. There were no significant differences between any phases in basic semen findings and parameters of the sperm chromatin structure assays. Regarding sperm motion characteristics, the average linear velocity, beat-cross frequency, and sperm motility index significantly decreased after the second vaccine dose (P=0.018, P=0.003, and P=0.027, respectively), with no significant differences between any two phases by post-hoc pairwise comparisons. Conclusion(s): After COVID-19 mRNA vaccination, while sperm motion characteristics might fluctuate, no apparent deterioration of basic sperm parameters or sperm DNA integrity was observed. Given the adverse effects of COVID-19 on sperm, our findings suggest that there might be no reason to refrain from vaccination for healthy individuals.Copyright © 2023 Asian Pacific Journal of Reproduction Produced by Wolters Kluwer- Medknow.
ABSTRACT
Background: Increasing availability of highly effective cystic fibrosis (CF) transmembrane conductance regulator (CFTR) modulator therapy (HEMT) has improved the quality of life and long-term prognosis for many people with CF. Thus, more people with CF are considering parenthood. Almost all menwith CF (MwCF) are infertile because of congenital bilateral absence of the vas deferens (CBAVD). Based on CF animal models, CBAVD occurs early in gestation and is unlikely to be reversible using HEMT, but assisted reproductive techniques (ARTs) can enable MwCF to father children using the sperm in their testes. Animal reproductive models suggest no HEMT teratogenicity, and the amount of exposure of the fetus to HEMT via absorption of seminal fluid through the vaginal wall is predicted to be negligible, although to ensure no sperm exposure to HEMT, the life span of sperm would require MwCF to discontinue CFTR modulators for approximately 3 months before ART. Because abrupt discontinuation of CFTR modulators may result in health decline, MwCF and their providers must consider all potential risks. There are no published data in MwCF regarding use of HEMT during conception and partner pregnancy. Method(s): Beginning in August 2021, CF center staff in the United States, United Kingdom, and Australia completed a two-page anonymous questionnaire regarding MwCF who used CFTR modulators during ART (sperm retrieval and in vitro fertilization) or natural conception with subsequent partner pregnancy. Result(s): Providers have submitted 34 surveys for MwCF on CFTR modulators whose partner became pregnant after use of ART (n = 32) or natural conception (n = 2). The median age of the samplewas 32 (range 24- 43). Fifteen were homozygous for F508del, median percentage predicted forced expiratory volume in 1 second was 76% (range (22-111%), and median body mass index was 24 kg/m2 (range 18.5-32.1). Twenty-three were taking elexacaftor/tezacaftor/ivacaftor. The median time that MwCF were taking CFTR modulators before partner conception was 18 months (range 0-82). One newly diagnosed man initiated HEMT after sperm retrieval. Four MwCF stopped CFTR modulators before sperm retrieval, one of whom experienced pulmonary decline. None of the 19 MwCF whose condom use during pregnancy was known used condoms. Fetal complications in partners of MwCF included three first-trimester miscarriages, two* COVID, two breech presentation, two* vaginal bleeding, and one vasa previa. None of the complications were deemed definitively related to use of CFTR modulators. One MwCF experienced testicular infection after sperm retrieval#. Postpartum complications included three# infants with hypoxemia requiring neonatal intensive care unit stay, three maternal blood loss, one forceps delivery, and one caesarean section. No congenital anomalies were reported for any infant. (*/# overlap). Conclusion(s): Use of CFTR modulator therapy during partner conception and pregnancy in 34 MwCF has not resulted in higher-than-expected miscarriage rates or congenital anomalies. Providers should consider the risk to the health of MwCF combined with the lack of teratogenicity in animal reproductive models and limited safety data in the human fetus before discontinuing CFTR modulators before ART or natural partner conception.

ABSTRACT
Background: It is well knowledge that various viral illnesses may interfere with a man's ability to father children. Through the angiotensin-converting enzyme-2 receptor, which is highly concentrated in testicular tissue, the corona virus illness known as COVID-19 may cause harm to several organs. On the other hand, there is a paucity of data about the transmission of severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) in sperm, as well as the virus's influence on spermatogenesis and the capacity for fertility. We intended to look into whether or not COVID-19 guys' sperm contained SARS-CoV-2 as well as examine how COVID-19 affected the overall quality of the sperm and the degree to which it's DNA was fragmented. Material(s) and Method(s): The survey was conducted between May 2022 to October 2022, with the participation of 40 male COVID-19 patients who were between the ages of 19 and 45 and enrolled at the RSDKS, Government Medical College, Ambikapur, Chhattisgarh. We tested each sample of sperm with a real-time reverse transcriptase and found no abnormalities. At the time of the initial sample, which took place during COVID-19, a comprehensive examination of the sperm was carried out. This analysis included the calculation of the sperm DNA Fragmentation Index. After 74 days had passed since the first sample, we were able to get the second specimen and carried out the aforementioned tests once again. Result(s): All of the sperm samples that were examined using real-time reverse transcription-polymerase chain reaction (RT-PCR) came back negative for SARS-CoV-2. These samples were taken during the first and second sampling. The initial sample had considerably lower levels of fructose, semen volume, vitality, total motility, sperm concentration, total sperm count, percentage of normal morphology, and cytoplasmic droplet percentage than the subsequent samples. On the other hand, the agglutination of the semen, the percentage of head defects, the DNA Fragmentation Index, the liquefaction time, the viscosity of the semen, and the number of leukocytes all rose. At the second sample, these results were inverted, but not to the level that would be considered optimal. These results all had a p-value less than 0.05, meaning they were statistically significant. As a result, COVID-19 has a detrimental impact on the characteristics of the sperm, including the sperm DNA fragmentation index. Conclusion(s): The quality of the semen remained low up until the second time it was sampled, despite the fact that we were unable to discover SARS-CoV-2 in the sample. It is recommended that assisted reproductive technology (ART) clinics and sperm banking facilities evaluate the quality of the sperm produced by males infected with COVID-19 and exclude men who have a history of being infected with SARS-CoV-2 until the men's sperm quality recovers to normal.Copyright © 2023 Ubiquity Press.

ABSTRACT
Background: As there is an increase of infections in the male population, concerns have emerged about the potential impact of COVID-19 on male fertility. This study aimed to investigate systematically the presence of SARS-CoV-2 RNA in the semen and determine the contagiousness of sperm and its influence on male fertility after COVID-19 infection. Method(s): Electronic searches were performed in PubMed/ MEDLINE, SCOPUS, and Web of Science up to December 2021 regarding the existence of SARS-CoV-2 RNA in seminal fluid, testis, and the effects of COVID-19 on male reproduction. A total of 24 original articles were included in the study. Result(s): The presence of a virus in a semen sample is still a topic of discussion and research due to the small number of studies. Only two studies identified viral mRNA in the semen of infected men;others stated semen is not infectious with SARS-CoV-2 at one week or more after COVID-19 infection. However, couples with a desire for pregnancy should be warned that sperm quality after COVID-19 infection can be suboptimal. According to the existing clinical data, this virus could infect the testis and the male genital tract and cause damage to male fertility. It shows a negative impact on male reproductive health, inducing spermatogenic failure. However, the mechanism for testicular involvement remains doubtful. Conclusion(s): SARS-CoV-2 RNA was undetectable in all semen samples, but it may cause testicular involvement and impact the male reproductive system inducing spermatogenic failure.
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
Coronavirus disease 2019 (COVID 19) is caused by severe acute respiratory syndrome novel coronavirus 2 (SARS-nCoV-2). It has been declared a pandemic by the World Health Organization (WHO) on March 11, 2020. Since then, several researchers have worked/ are working on this virus by a multifactorial approach to finding out the mechanism of entry, transmission route, post-infection replication process, survival, and post-recovery utilities. As we know, SARS, MERS, and Zika viruses have affected human reproductive potentials, consequently, COVID 19 also can affect both men's and women's reproductive potential through ACE2 macromolecule. This study aimed to summarize the role of ACE2-macromolecule in COVID 19 entry and further processes in the reproductive path of both men and women. Research articles were searched in NCBI-NLM, Google Scholar, and Scopus databases. We searched based on the phrase ―COVID 19”, ―ACE2”, ―ACE2 in testes”, ―ACE2 in the female reproductive tract”, ―ACE2 during pregnancy”, ―ACE2 during early embryo”, ―COVID 19 and impact in human reproduction” and selected the articles for summarizing this article. Most recent articles and the mechanism of COVID 19 were selected for our understanding. The results of the study revealed that COVID 19 impacts the reproductive potential of both men and women. Testes are the most vulnerable organ prone to infection in men, and vaginal fluid and the uterus could be the choice of infection in the female. Till now, COVID 19 has not been directly detected in semen samples and vaginal fluid. Results of the study can be concluded that ACE2 plays a major role in COVID 19 infection, ACE2 expression could Angiotensin Converting Enzyme 2 (ACE2) - A macromolecule and its impact on human reproduction. © 2022, Editorial board of Journal of Experimental Biology and Agricultural Sciences.

ABSTRACT
Mammalian seminal plasma contains a multitude of bioactive components, including lipids, glucose, mineral elements, metabolites, proteins, cytokines, and growth factors, with various functions during insemination and fertilization. The seminal plasma protein PDC-109 is one of the major soluble components of the bovine ejaculate and is crucially important for sperm motility, capacitation, and acrosome reaction. A hitherto underappreciated function of seminal plasma is its anti-microbial and antiviral activity, which may limit the sexual transmission of infectious diseases during intercourse. We have recently discovered that PDC-109 inhibits the membrane fusion activity of influenza virus particles and significantly impairs viral infections at micromolar concentrations. Here we investigated whether the antiviral activity of PDC-109 is restricted to Influenza or if other mammalian viruses are similarly affected. We focused on Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), the etiological agent of the Coronavirus Disease 19 (COVID-19), thoroughly assessing PDC-109 inhibition with SARS-CoV-2 Spike (S)-pseudotyped reporter virus particles, but also live-virus infections. Consistent with our previous publications, we found significant virus inhibition, albeit accompanied by substantial cytotoxicity. However, using time-of-addition experiments we discovered a treatment regimen that enables virus suppression without affecting cell viability. We furthermore demonstrated that PDC-109 is also able to impair infections mediated by the VSV glycoprotein (VSVg), thus indicating a broad pan-antiviral activity against multiple virus species and families.

ABSTRACT
Introduction. In the context of the COVID-19 pandemic, it seems relevant to study the clinical features and the effect of the SARS-CoV-2 virus on the reproductive system and male fertility. The study objective was to assess the intensity of oxidative processes in the seminal plasma of men with pathozoospermia after suffering a COVID-19 infection. Materials and methods. Spermogram parameters were assessed in accordance with the criteria of the 2010 WHO Guidelines, 5th edition, for the study and processing of human ejaculate two to three months after the patient received a negative polymerase chain reaction result of a nasopharyngeal swab for SARS-CoV-2 DNA. The intensity of free radical processes in seminal plasma was investigated by the method of chemiluminescence induced by ions of bivalent iron. Results. A decrease in sperm motility and an increase in the number of leukocytes were found in men with pathozoospermia who had undergone COVID-19 infection. There are lower levels of indicators such as ejaculate volume, total sperm concentration and the number of morphologically normal sperm forms. An increased ability to generate reactive oxygen species in seminal plasma was revealed in pathozoospermia and COVID-19. Conclusions. The results obtained indicate that SARS-CoV-2 affects the male reproductive system directly or indirectly and has a negative effect on male reproductive health, causing the activation of lipid peroxidation processes and spermatogenic insufficiency. © 2021 Cyrillo-Methodian Research Centre of BAS.

ABSTRACT
INTRODUCTION AND OBJECTIVE: SARS-CoV-2 can invade different testicular cell types, such as spermatogonia, spermatids, Sertoli, and Leydig cells. We investigated the viral presence inside the sperm of negative PCR infected men up to 3 months after discharge from the hospital. METHODS: This cross-sectional study included 13 of a 26 moderate-to-severe SARS-CoV-2 infected men cohort (mean 34.3 ± 6.5 years;range: 21-50 years old). Patients were enrolled 30 to 90 days after the diagnosis. Semen samples were obtained by masturbation and processed within one hour according to WHO guidelines. All patients were PCR negative for the virus in the ejaculate. Samples were liquefied for 30 min at room temperature in 0.1M phosphate buffer before centrifuging at 500 g for 10 min. The supernatant was removed, and pellets were fixed in 2,5% v/v glutaraldehyde in 0.1M phosphate buffer for 2h at 4°C, post-fixed in 1% OsO4 for 1h at 4°C, stained overnight in 1% aqueous uranyl acetate. Then, the pellets were dehydrated sequentially in 30%, 70%, and 100% ethanol and embedded in epoxy resin. Ultrathin sections (70nm) were obtained in an ultramicrotome, collected on nickel grids, and double-stained by uranyl acetate and lead citrate. Micrographs were obtained with a Jeol JEM 1010 electron microscope (Tokyo, Japan, 80 kV). RESULTS: We identified viruses inside spermatozoa in 9/13 patients up to 90 days after discharge from the hospital. Moreover, in all 13 men, a type of DNA-based extracellular traps, probably in a cfDNAdependent manner, like described in the COVID-19 systemic inflammatory response. FIGURE: High magnification electron micrograph of a spermatozoon with the nucleus (nu) displaying the typical condensed chromatin. The remained cytoplasm contains several viral particles (ranging in diameter from 90 to 110 nm). The inset corresponds to a higher magnification of the boxed area containing two virions, showing the SARS-CoV-2 characteristics: viral envelope (white arrowhead), nucleocapsids (black arrowhead), and spike-like projections (white arrow). CONCLUSIONS: Although SARS-CoV-2 is not found in the infected men's semen, it was intracellularly present in the spermatozoa. The potential implications for assisted conception should be addressed.

ABSTRACT
OBJECTIVE: To evaluate the effect of COVID-19 in sperm cryopreservation processes, including functional parameters evaluated pre-cryopreservation and post-thaw, and to compare post-thaw results from COVID-19 patients to samples from others systemic and andrological Disease MATERIALS AND METHODS: In this cross-sectional study, 37 semen samples of male patients aged 18 to 45 years at Division of Urology, Department of Surgery, Hospital das Clinicas of the University of Sao Paulo or at Androscience- Science and Innovation Center in Andrology, High-Complex Clinical and Research Andrology Laboratory, were initially recruited from April 2020 to April 2021. Patients were categorized as acute COVID-19 (n=15), confirmed by RT-PCR (COVID-19 group), and healthy individuals with normozoospermic semen samples (n=22;Control group). Were evaluated seminal parameters, cryosurvival rates (%), mitochondrial activity (%;3,30 -diaminobenzidine stain), reactive oxygen species levels (ROS;chemiluminescent technique) and DNA fragmentation (%;SCSA method) in precryopreservation and post-thaw samples. Samples were cryopreserved by the slow freezing technique. A complementary retrospective study was performed comparing post-thawed samples from COVID-19 group with data from patients with others male diseases: Male infertility (n=35);Severe infertility (n=62), caused severe oligozoospermia, grade 3 varicocele, gonadal dysgenesis, testicular nodule, testicular hypotrophy;testicular cancer (n=55);and other malignant diseases (leukemia, lymphoma, sarcoma, multiple myeloma;n=30). Was used T-test to statistical analysis (p<0.05). RESULTS: Macroscopy analysis of COVID-group revealed abnormal viscosity in 53.33%, semen volume = 4.50 ± 1.72 ml and pH = 8.13 ± 0.23. COVID-19 fresh samples demonstrated mean of progressive motility = 29.07±16.83%, sperm morphology = 2.07±1.58%, and DNA fragmentation index = 42.91±33.38%. Cryopreservation decreased progressive motility (to 5.39±7.92%;p=0.02), sperm vitality (70.46±8.50 vs. 72.20±23.27;p=0.042) and ROS (0.516±0.978 vs. 4.393±9.956 x 104 cpm;p=0.018). When we compared with cryopreserved normozoospermic samples, there was observed a significant difference in HDS (p=0.002). Cryosurvival rate from COVID-19 samples was 19.93;19.71%, and had significant difference when compared with severe infertility (40.16;31.05%;p=0.003), and other malignant diseases (53.14;28.55%, <0.001). CONCLUSIONS: Seminal samples from patients with COVID-19 showed reduced fertile potential, especially when compared to the reference values. In the comparisons performed with samples from patients with different andrological diagnoses, common in the specialized andrology laboratory routine, we can suggest that samples from patients with the acute form of COVID-19 had the worst quality, with low cryosurvival rates. This information contribute to the conduct of these patients during assisted reproduction routines and preservation of male fertility. IMPACT STATEMENT: It will contribute to conducts in the cryopreservation of sperm in patients with acute COVID-19.
ABSTRACT
OBJECTIVE: The current COVID-19 pandemic, caused by Severe Acute Respiratory Syndrome Corona Virus-2 (SARS-CoV-2), poses several catastrophic threat s globally including those on economy, lifestyle and health. Although the respiratory tract is the primary proliferation site of the virus, its effects on other organs and organ systems is devastating. One of the potential tar-gets for SARS-CoV-2 invasion is the male reproductive system owing to the presence of viral receptors i.e., ACE2 and TMPRSS2 in the testis. Currently there are differing views in literature on whether SARS-CoV-2 infection has any short term and long term effects on male fertility. This pilot study was aimed to assess the impact of viral infection on crucial reproductive processes at the molecular level even after recovery. MATERIALS AND METHODS: We performed a label free quantitative proteomic analysis of semen procured from 17 COVID-19 recovered and 10 healthy fertile individuals using high resolution mass spectrometry. RESULTS: Our proteomic analysis resulted in the identification of 48 differentially expressed proteins of which 27 were upregulated and 21 were downregulated in recovered individuals. Further bio-informatic analysis revealed the dysregulation of several biological processes linked to male reproductive functions. Pathways like regulation of cell motility, regulation of adhesion, sperm-egg recognition, response to testosterone, extracellular matrix adhesion and endopeptidase activity were found to be downregulated in the recovered group. Moreover, the down regulation of two candidate proteins;Semenogelin 1 and Prosaposin which are related to male fertility were also validated using targeted proteomic approach CONCLUSIONS: This extensive proteomic study sheds light on the possible effects of SARS-CoV2 infection on reproductive functions and subsequently on male fertility even after apparent recovery from viral infection. IMPACT STATEMENT: The semen proteomic analysis of the COVID-19 recovered patients portrays a clear scenario of alteration of reproductive function in response to viral infection after clinical recovery, thus corroborating a possibility of virus-mediated impact on male infertility. A similar kind of study on large cohort will also direct the way to combat the viral effect on male reproductive function. This study would guide clinicians in counselling couples affected by COVID-19 as to the possible short term and long term effects on male reproductive potential.

ABSTRACT
Under physiological conditions, reactive oxygen species (ROS) play pivotal roles in various processes of human spermatozoa. Indeed, semen requires the intervention of ROS to accomplish different stages of its maturation. However, ROS overproduction is a well-documented phenomenon occurring in the semen of infertile males, potentially causing permanent oxidative damages to a vast number of biological molecules (proteins, nucleic acids, polyunsaturated fatty acids of biological membrane lipids), negatively affecting the functionality and vitality of spermatozoa. ROS overproduction may concomitantly occur to the excess generation of reactive nitrogen species (RNS), leading to oxidative/nitrosative stress and frequently encountered in various human pathologies. Under different conditions of male infertility, very frequently accompanied by morpho-functional anomalies in the sperm analysis, several studies have provided evidence for clear biochemical signs of damages to biomolecules caused by oxidative/nitrosative stress. In the last decades, various studies aimed to verify whether antioxidant-based therapies may be beneficial to treat male infertility have been carried out. This review analyzed the results of the studies published during the last ten years on the administration of low-molecular-weight antioxidants to treat male infertility in order to establish whether there is a sufficient number of data to justify antioxidant administration to infertile males. An analysis of the literature showed that only 30 clinical studies tested the effects of the administration of low-molecular-weight antioxidants (administered as a single antioxidant or as a combination of different antioxidants with the addition of vitamins and/or micronutrients) to infertile males. Of these studies, only 33.3% included pregnancy and/or live birth rates as an outcome measure to determine the effects of the therapy. Of these studies, only 4 were case-control studies, and only 2 of them found improvement of the pregnancy rate in the group of antioxidant-treated patients. Additionally, of the 30 studies considered in this review, only 43.3% were case-control studies, 66.7% enrolled a number of patients higher than 40, and 40% carried out the administration of a single antioxidant. Therefore, it appears that further studies are needed to clearly define the usefulness of antioxidant-based therapies to treat male infertility.
