Abstract
Infertility affects approximately one-sixth of couples globally, with the incidence of male infertility steadily increasing. However, our understanding of the impact of viral infections on fertility remains limited. This review consolidates findings from previous studies, outlining 40 viruses identified in human semen and summarizing their key characteristics, modes of transmission, and their effects on both the reproductive and endocrine systems. Furthermore, it elucidates potential pathogenic mechanisms and treatment prospects of viruses strongly associated with male infertility. This synthesis will enhance our comprehension of how viral infections influence male reproductive health, offering valuable insights for future research as well as the diagnosis and treatment of infectious infertility.

Abstract
Background The seminal virome and its implications for fertility remain poorly understood. To date, there are no defined panels for the detection of viruses of clinical interest in seminal samples. Results In this study, we characterized the human seminal virome based on more than 1,000 studies published over the last five years. Conclusions The number of studies investigating viruses that occur in human semen has increased, and to date, these studies have been mostly prospective or related to specific clinical findings. Through the joint analysis of all these studies, we have listed the viruses related to the worsening of seminal parameters and propose a new panel with the main viruses already described that possibly affect male fertility and health. This panel can assist in evaluating semen quality and serve as a tool for investigation in cases of infertility.

Abstract
3'-Azido-3'-deoxythymidine (AZT), an antiretroviral drug, is often adopted in the therapy for human immunodeficiency virus (HIV) infection, and the characteristics of AZT transport at the blood-testis barrier (BTB) were investigated in this study. In the integration plot analysis that evaluates the transport activity in vivo, the apparent influx clearance of [3H]AZT was significantly greater than that of [14C]D-mannitol, a non-permeable paracellular transport marker. In the uptake study in vitro with TM4 cells derived from mouse Sertoli cells, [3H]AZT uptake exhibited a time- and concentration-dependent manner, of which Km and Vmax values being 20.3 µM and 102 pmol/(min·mg protein), respectively. In the inhibition analysis, [3H]AZT uptake was not affected by extracellular inorganics and some substrates of transporters putatively involved in AZT transport. In the further inhibition analyses to elucidate the characteristics of AZT transport, [3H]AZT uptake was strongly reduced in the presence of several nucleosides, that are categorized as 2'-deoxynucleosides with pyrimidine, whereas little effect on [3H]AZT uptake was exhibited in the presence of other nucleosides, nucleobases, and antiretrovirals. These results suggest the influx transport of AZT from the circulating blood to the testis, and the involvement of carrier-mediated process at the BTB, which selectively recognizes 2'-deoxynucleosides with a pyrimidine base.

Abstract
Infections may act with variable impact on the physiopathology of the reproductive organs, determining infertility or reducing the outcomes of assisted reproduction technology. The aim of this narrative review is to describe the existing evidence regarding the pathogens with a supposed or recognized role in reproductive medicine. Viral hepatitis, as well as HIV, can reduce sperm quality. Syphilis carries a risk of erectile dysfunction and increased endometrial thickness. Chlamydia is the main cause of pelvic inflammatory disease. In relation to Mycoplasma and Ureaplasma spp., only few species seem to show a correlation with infertility and poor in-vitro fertilization outcomes. There is evidence of a role for bacterial vaginosis in early pregnancy loss. HPV infection in males seems to determine infertility. Herpesviruses are more a risk for fetuses than for fertility itself. Zika virus is responsible for altered early embryo development and waiting to conceive is recommended in suspected or confirmed cases. The impact of SARS-CoV-2 is yet to be elucidated. Rubella and toxoplasmosis can provoke important congenital defects and therefore screening is mandatory before conception; a vaccine for Rubella is recommended. Further and well-designed studies are still needed to better elucidate the role of some infectious agents, to improve fertility and its treatments.

Abstract
Emerging viral infections continuously pose a threat to human wellbeing. Several RNA viruses have managed to establish access to the male reproductive tract and persist in human semen. The sexual transmission of the virus is of critical public concern. The epidemiological inferences are essential to understand its complexity, particularly the probability of viral transmission from asymptomatic patients or those in the incubation period or from the patient who was previously infected and now fully recovered. From the clinical perspective, negative impacts in the male reproductive tract associated with RNA virus infection have been described, including orchitis, epididymitis, impaired spermatogenesis, and a decrease in sperm quality, which can affect male fertility at different time intervals. The disruption of anatomical barriers due to inflammatory responses might enable the viral invasion into the testis, and the immune privilege status of testes might facilitate a sustained persistence of the virus in the semen. In this review, the current knowledge about other RNA viruses that affect male reproductive health provides the framework to discuss the impact of the SARS-CoV-2 pandemic. The molecular mechanisms, sexual transmission, and viral impacts for mumps, HIV, Zika, and Ebola viruses are explored. We discuss the currently available information on the impact of SARS-CoV-2 and its sequelae in the male reproductive tract, particularly regarding presence in semen, its impact on sexual organs, and sperm quality. To date, no sexual transmission of SARS-CoV-2 has been reported, whereas the identification of viral particles in semen remains conflicting. In the purview of the earlier conducted analyses, it is essential to investigate further the long-term health impacts of SARS-CoV-2 on the male reproductive tract.

Abstract
Sexual issues tend to go unaddressed in human immunodeficiency virus (HIV) management, although overt sexual dysfunctions are more prevalent in people living with HIV than uninfected people. Erectile dysfunction is the most frequent sexual problem, with a prevalence of 30–50% even in men <40 years of age, but other issues such as loss of libido and ejaculatory disorders should not be overlooked. Peculiar factors related to HIV infection (e.g., fear of virus transmission, changes in body image, HIV-related comorbidities, HIV distress and stigma), alongside classical factors non-related to HIV, should be considered when approaching sexual problems in HIV patients. For this reason, the diagnostic and therapeutic workout of sexual dysfunction in the context of HIV requires a multidisciplinary approach, involving specialists in both infectious diseases and sexual medicine. This narrative review presents an overview of current knowledge on sexual dysfunction in HIV men, deepening the factors driving and taking part in these issues, providing advice for the clinical approach, and underlining the importance of caring for sexual health to improve the quality of life of HIV patients.

Abstract
There are no published studies of fertility measurements in people living with perinatally acquired HIV (PaHIV). We performed fertility investigations in 25 adults with PaHIV. Seven (78%) men had sperm morphology normal forms (%) below the fifth centile for the general population with four (44%) having no normal forms. Mean (SD) serum anti-Müllerian hormone level was 19.4 (9.5) pmol/l; lower than expected for this age group. A larger study is needed to verify our findings.

Abstract
Male infertility is linked to some viral infections including human papillomavirus (HPV), herpes simplex viruses (HSV) and human immunodeficiency viruses (HIVs). Almost nothing is known about severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) effect on fertility. The possible risk factors of coronavirus disease 2019 (COVID-19) infection on fertility comes from the abundance of angiotensin-Converting Enzyme-2 (ACE2), receptor entry of the virus, on testes, a reduction in important sex hormone ratios and COVID-19-associated fever. Recent studies have shown a gender difference for COVID-19 rates and comorbidity. In this review, we will discuss the potential effect of COVID-19 on male fertility and talk about what needs to be done by the scientific community to tackle our limited understanding of the disease. On the other side, we will focus on what is known so far about the risk of COVID-19 on pregnancy, neonatal health and the vertical transfer of the virus between mothers and their neonates. Finally, because reproduction is a human right and infertility is considered a health disease, we will discuss how assisted reproductive clinics can cope with the pandemic and what guidelines they should follow to minimise the risk of viral transmission.

Abstract
Studies of vertebrate genomes have indicated that all species contain in their chromosomes stretches of DNA with sequence similarity to viral genomes. How such 'endogenous' viral elements (EVEs) ended up in host genomes is usually explained in general terms such as 'they entered the germ line at some point during evolution'. This seems a correct statement, but is also rather imprecise. The vast number of endogenous viral sequences suggest that common routes to the 'germ line' may exist, as relying on chance alone may not easily explain the abundance of EVEs in modern mammalian genomes. An increasing number of virus types have been detected in human semen and a growing number of studies have reported on viral infections that cause male infertility or subfertility and on viral infections that threaten in vitro fertilisation practices. Thus, it is timely to survey the pathway(s) that viruses can use to gain access to the human germ line. Embryo transfer and semen quality studies in livestock form another source of relevant information because virus infection during reproduction is clearly unwanted, as is the case for the human situation. In this review, studies on viruses in the male and female reproductive tract and in the early embryo will be discussed to propose a plausible viral route to the mammalian germ line.

Abstract
HIV-1 sexual transmission occurs mostly through contaminated semen, which is a complex mixture of soluble factors with immunoregulatory functions and cells. It is well established that semen cells from HIV-1-infected men are able to produce the virus and that are harnessed to efficiently interact with mucosal barriers exposed during sexual intercourse. Several cofactors contribute to semen infectivity and may enhance the risk of HIV-1 transmission to a partner by increasing local HIV-1 replication in the male genital tract, thereby increasing the number of HIV-1-infected cells and the local HIV-1 shedding in semen. The introduction of combination antiretroviral therapy has improved the life expectancy of HIV-1 infected individuals; however, there is evidence that systemic viral suppression does not always reflect full viral suppression in the seminal compartment. This review focus on the role semen leukocytes play in HIV-1 transmission and discusses implications of the increased resistance of cell-mediated transmission to immune-based prevention strategies.

Abstract
Male fertility preservation has been steadily increasing over the past two decades. Significant improvements have been achieved in the treatment modalities of cancer and other severe chronic medical conditions, leading to an increase in patient survivorship and the resulting demand for future parenthood. Recognition and proper patient counselling before commencing therapies with a potential gonadotoxic effect are of paramount importance. Similarly, nonmedically indicated fertility preservation is on the rise. Social sperm banking, gender dysphoria prior to affirmation procedures and posthumous reproduction preservation are becoming more common. When timing and logistics are appropriate, sperm cryopreservation is considered the gold standard for fertility preservation. Testicular tissue and spermatogonial stem cell autotransplantation is considered experimental and represents a promising alternative for pre-pubertal patients. The current paper aims to review the recent trends in male fertility preservation, the common indications for sperm cryopreservation, techniques for sperm retrieval and experimental frontiers.

Abstract
BACKGROUND HIV-1 infected patients show impaired semen parameters. Currently, it is not clear whether HIV-1 infection itself or antiretroviral therapy have an effect on semen parameters. We aim evaluate semen quality in a large cohort of fertile HIV-1 infected men under stable highly active antiretroviral therapy (HAART) and to assess the effect of HAART type and duration on semen parameters. MATERIALS AND METHODS Between January 2010 and June 2014, we enrolled in a retrospective case-control study 770 HIV-1 patients under stable HAART asking a reproductive counselling with their HIV negative partner. Co-infections with HBV or HCV, genital tract infections and known causes of infertility represented exclusion criteria. Semen samples were analysed and compared with the WHO reference values. A multivariate analysis including HAART type and duration, age, viral load and CD4 count, was performed on 600 patients out of 770. RESULTS The median values of all semen parameters were significantly lower among HIV-1 infected patients compared to the WHO reference group, with a significant proportion of patients having values below the 5th percentile of the WHO reference value. In a multivariate analysis, only age and viral load negatively impacted progressive motility (β -0.3 (95% CI: -0.5; -0.0) %, p<0.05) and semen morphology (β -0.00 (95% CI: -0.00; -0.00) %, p≤0.01), while no associations were detected as regards HAART type and duration. CONCLUSIONS HIV-1 infected patients showed a significant impairment of semen parameters compared to the reference values. HAART type and duration showed no associations with semen quality. Further research is needed to investigate implications for clinical care of HIV infected men desiring a child.

Abstract
HIV-1-affected couples' desire to have children and free sexual intercourses with the use of pre-exposure prophylaxis for the negative partner has emerged as an alternative option to assisted reproduction in aviremic patients under highly active antiretroviral therapy (HAART). It is already known that sperm quality may be impaired in HIV-infected men. The underlying physiopathological mechanism is still debated. The aim of this study was to evaluate the effects of HAART on sperm DNA fragmentation, comparing HIV-1-infected patients taking HAART versus naïve HIV-1-infected patients. This is a prospective case-control study. Sperm nuclear DNA fragmentation rate was evaluated by the sperm chromatin dispersion test in 77 HIV-infected men: 53 HIV-1 patients receiving HAART (Group 1) versus 24 naïve HIV-1 patients not receiving HAART (Group 2). Complete semen analysis was performed according to WHO 2010 recommendations. Patients with HBV infection or HCV infection coinfections and genital tract infections wre excluded. All the patients did not present any clinical signs of their disease. Seminal parameters were examined in the two groups, showing no significant differences. Increased sperm DNA fragmentation > 30% was demonstrated in 67.9% of patients in Group 1 and 37.5% of patients in Group 2, respectively ( p = .02). A positive but nonsignificant trend toward increased fragmentation was reported with advancing patients' age. In conclusion, sperm nuclear fragmentation rate is increased in HIV-1-infected patients taking HAART compared to HIV-1 patients not receiving HAART.

Abstract
OBJECTIVES To estimate the relationship between HIV natural history and fertility by duration of infection in east and southern Africa before the availability of antiretroviral therapy and assess potential biases in estimates of age-specific subfertility when using retrospective birth histories in cross-sectional studies. DESIGN Pooled analysis of prospective population-based HIV cohort studies in Masaka (Uganda), Kisesa (Tanzania) and Manicaland (Zimbabwe). METHODS Women aged 15-49 years who had ever tested for HIV were included. Analyses were censored at antiretroviral treatment roll-out. Fertility rate ratios were calculated to see the relationship of duration of HIV infection on fertility, adjusting for background characteristics. Survivorship and misclassification biases on age-specific subfertility estimates from cross-sectional surveys were estimated by reclassifying person-time from the cohort data to simulate cross-sectional surveys and comparing fertility rate ratios with true cohort results. RESULTS HIV-negative and HIV-positive women contributed 15 440 births and 86 320 person-years; and 1236 births and 11 240 000 person-years, respectively, to the final dataset. Adjusting for age, study site and calendar year, each additional year since HIV seroconversion was associated with a 0.02 (95% confidence interval 0.01-0.03) relative decrease in fertility for HIV-positive women. Survivorship and misclassification biases in simulated retrospective birth histories resulted in modest underestimates of subfertility by 2-5% for age groups 20-39 years. CONCLUSION Longer duration of infection is associated with greater relative fertility reduction for HIV-positive women. This should be considered when creating estimates for HIV prevalence among pregnant women and prevention of mother-to-child transmission need over the course of the HIV epidemic and antiretroviral treatment scale up.

Abstract
Semen hyperviscosity (SHV) is one of the factors involved in deficiency in sperm function. This research aimed to evaluate seminal plasma total antioxidant capacity (TAC)
and malondialdehyde (MDA) levels in infertile patients with hyperviscous and non-hyperviscous semen samples to understand whether hyperviscous semen is associated with
oxidative damage in infertile subjects. In this cross sectional study, 59 semen samples
were provided by fertile (n=12) individuals as control, infertile patients with normal viscosity (n=25) and infertile patients with hyperviscosity (n=22). After semen parameters examination, semen viscosity was studied by glass pipettes. Seminal plasma TAC and MDA
levels were measured by ferric reducing of antioxidant power (FRAP) and thiobarbituric
acid reaction (TBAR) methods, respectively. A probability less than 0.05 was considered
statistically significant throughout the article. The mean of sperm parameters including:
counts, motility and normal morphology in patients with hyperviscosity were significantly
lower than those in non-hyperviscosity patients (p<0.05, p<0.01 and p<0.001, respectively). The mean of seminal plasma TAC value in seminal plasma of non-hyperviscosity
patients (1710.31 ± 458.67 µmol/l) was significantly (p<0.01) higher than that of hyperviscosity group (1230.25 ± 352 µmol/l). A trend toward a higher mean of seminal plasma
MDA value was estimated for hyperviscous group compared with non-hyperviscous (1.01
± 0.41 nmol/ml vs. 0.94 ± 0.28 nmol/l); however, it was nonsignificant. Hyperviscous semen impairs seminal plasma TAC which is eventually associated with sperm membrane
lipid peroxidation.

Abstract
Sexually transmitted diseases (STDs) are caused by several pathogens, including bacteria, viruses and protozoa, and can induce male infertility through multiple pathophysiological mechanisms. Additionally, horizontal transmission of STD pathogens to sexual partners or vertical transmission to fetuses and neonates is possible. Chlamydia trachomatis, Ureaplasma spp., human papillomavirus, hepatitis B and hepatitis C viruses, HIV-1 and human cytomegalovirus have all been detected in semen from symptomatic and asymptomatic men with testicular, accessory gland and urethral infections. These pathogens are associated with poor sperm quality and decreased sperm concentration and motility. However, the effects of these STD agents on semen quality are unclear, as are the effects of herpes simplex virus type 1 and type 2, Neisseria gonorrhoeae, Mycoplasma spp., Treponema pallidum and Trichomonas vaginalis, because few studies have evaluated the influence of these pathogens on male infertility. Chronic or inadequately treated infections seem to be more relevant to infertility than acute infections are, although in many cases the exact aetiological agents remain unknown.

Abstract
Studies on the sperm-fertilizing capacity of HIV-seropositive men show conflicting results for reasons that are not yet clear. The aim of this study was to investigate the effects and relationships of some factors such as patient age, CD4(+) cells count, fathering offspring, concomitant sexually transmitted diseases (STD), and receipt of highly active anti-retroviral therapy (HAART) on sperm fertilizing capacity. Semen samples were collected from 33 HIV-seropositive men. Data on the above factors were acquired from a self-designed questionnaire. Computer-assisted sperm analysis, a hypo-osmotic swelling, and zona-free hamster oocyte penetration tests were performed according to criteria of the World Health Organization. CD4(+) cells in peripheral blood were examined using a flow cytometric (FCM) analyzer. Sperm vitality, sperm motility (grades a + b), total sperm motility, and sperm penetration rates were significantly higher in patients whose CD4(+) counts were ≧350/µl than in those whose CD4(+) counts were <350/µl (P < 0.05), and the parameters mentioned above were also significantly correlated with CD4(+) cell number (all P < 0.05). Significant differences in total sperm count and sperm tail swelling rate between patients co-infected with STD and without STD were observed (P < 0.05). Sperm penetration rate in patients receiving HAART was significantly higher than in those not receiving HAART (P < 0.05). Blood CD4(+) cell counts are an important indicator for evaluating sperm fertilizing capacity of HIV-seropositive men. After receiving HAART, the sperm penetration rate of HIV-seropositive men can be improved.

Abstract
OBJECTIVES To investigate semen quality in HIV patients under stable antiretroviral therapy (ART) compared with WHO 2010 reference values and on the sperm proteome level. DESIGN Between 2011 and 2013, we prospectively enrolled 116 HIV-positive men without hepatitis B or C co-infections from our outpatient department for infectious diseases. METHODS Patients received a comprehensive andrological work-up. Complete semen analysis was performed according to WHO 2010 recommendations, with each semen variable of the study population being compared with the WHO reference group (n~2000). Correlation analysis was done to investigate the influence of HIV surrogate parameters on semen quality. Two-dimensional gel electrophoresis and subsequent protein identification was performed to determine any differences in the sperm protein composition of the 15 HIV-positive patients and that of 15 age-matched healthy men. RESULTS Median values of all assessed semen parameters were within a normal range. However, for each semen variable, about 25% of patients had values below the fifth percentile of the WHO 2010 reference group. Disease-related parameters (CD4þ cell count, viral load, CDC stage, duration of disease, duration of ART, number and type of antiretroviral drugs) were not significantly correlated with any sperm parameter. Sperm proteome analysis identified 14 downregulated proteins associated with sperm motility and fertility. CONCLUSION This is the first study that compares all standard semen parameters in HIV positive patients under ART to WHO 2010 reference values. It provides evidence of impaired conventional semen parameters and altered sperm protein composition. Finally, HIV surrogate parameters are not suitable for predicting semen quality.

Abstract
Male accessory gland infection (MAGI) has been identified among those diagnostic categories which have a negative impact on the reproductive function and fertility in males (Rowe et al., World Health Organization Manual for the Standardised Investigation and Diagnosis of the Infertile Couple, Cambridge University Press, Cambridge, 1993). MAGI is a hypernym which groups the following different clinical categories: prostatitis, prostate-vesiculitis and prostate-vesiculo-epididymitis. Some of the characteristics they share are: common diseases, mainly have a chronic course, rarely cause obstruction of the seminal pathways, can have an unpredictable intracanicular spread to one or more sexual accessory glands of the reproductive tract, as well as to one or both sides. In this review, we show that all components involving the inflammatory response (from the agents which first trigger it to each component of the inflammatory response dynamic) can deteriorate conventional and/or non-conventional sperm parameters arising from one or more of the following mechanisms: altered secretory function of the epididymis, seminal vesicles, and prostate which reduce the antioxidant properties or scavenging role of the seminal plasma; deterioration of spermatogenesis; and (unilateral or bilateral) organic or functional sub-obstruction of the seminal tract.

Abstract
OBJECTIVE To study sperm parameters in patients infected with human immunodeficiency virus (HIV)-1 and to analyze mitochondrial DNA (mtDNA) in sperm according to the HIV treatment. DESIGN Observational study. SETTING University-affiliated teaching hospital. PATIENT(S) Thirty-two patients infected with HIV-1 and 31 noninfected healthy men provided semen samples. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) After DNA extraction, mtDNA level was assessed using real-time polymerase chain reaction (PCR) (LightCycler) in whole semen and in selected spermatozoa from 90% density centrifugation gradients. For each sample, mtDNA and β-globin gene sequences were amplified and PCR products were quantified. The mtDNA-to-β-globin ratio expressed the number of mtDNA copies per cell. RESULT(S) Compared with the control group, several sperm parameters were altered in patients with HIV. The number of mtDNA copies per cell in whole semen was increased in HIV-infected patients (6.3±6.3 vs. 3.5±3.2). However, there was no statistically significant difference in mtDNA copy number in the spermatozoa obtained after density gradient centrifugation. The number of nucleoside analogue reverse transcriptase inhibitors (NRTI) taken by patients during treatment significantly influenced the mtDNA level in sperm (1 NRTI 7.6±8.1, 2 NRTIs 7.0±5.1, 3 NRTIs 3.2±2.1). CONCLUSION(S) Using a specific method to measure sperm mtDNA, we demonstrated a decrease of mtDNA copies in spermatozoa after use of NRTIs with known mitochondrial toxicity.

Abstract
Despite semen being the main vector of human immunodeficiency virus (HIV) dissemination worldwide, the origin of the virus in this bodily fluid remains unclear. It was recently shown that several organs of the male genital tract (MGT) are infected by HIV/simian immunodeficiency virus (SIV) and likely to contribute to semen viral load during the primary and chronic stages of the infection. These findings are important in helping answer the following questions: (i) does the MGT constitute a viral reservoir responsible for the persistence of virus release into the semen of a subset of HIV-infected men under antiretroviral therapy, who otherwise show an undetectable blood viral load? (ii) What is the aetiology of the semen abnormalities observed in asymptomatic HIV-infected men? (iii) What is the exact nature of the interactions between the spermatozoa, their testicular progenitors and HIV, an important issue in the context of assisted reproductive techniques proposed for HIV-seropositive (HIV+) men? Answers to these questions are crucial for the design of new therapeutic strategies aimed at eradicating the virus from the genital tract of HIV+ men--thus reducing its sexual transmission--and for improving the care of serodiscordant couples wishing to have children. This review summarizes the most recent literature on HIV infection of the male genital tract, discusses the above issues in light of the latest findings and highlights future directions of research.

Abstract
The aims of this study were (a) to determine the prevalence of subjects with semen hyperviscosity (SHV) in a large population of male partners of subfertile couples; (b) to identify any correlation between SHV and infections or inflammation of the genital tract; (c) to assess the effects of therapeutic approaches for treating SHV; and (d) to assess sperm kinetic parameters after successful treatment of SHV. A retrospective study of 1 833 male partners of subfertile couples was conducted. Next, clinical, seminal, bacteriological and ultrasound studies involving 52 subjects suffering from SHV were performed, and the SHV was classified as being mild (length of thread > 2 cm and <or= 4 cm), moderate (> 4 cm and <or= 6 cm) or severe (> 6 cm). The prevalence of SHV was observed in 26.2% (480) of the subjects, with 13.2% suffering from mild, 6.6% from moderate and 6.4% from severe SHV. Treatment was completely successful in only 27 subjects (52.0%), primarily in those who had mild basal SHV with a positive semen culture. In these subjects, progressive motility percentage, straight line velocity and linearity were significantly higher than pre-treatment levels. SHV is often found in subjects with subfertility. Pathogenesis was strictly related to infective/inflammatory factors in only 48.0% of cases; therefore, it is possible that biochemical, enzymatic or genetic factors have a role in this condition.

Abstract
Despite semen being the main vector of human immunodeficiency virus (HIV) dissemination worldwide, the origin of the virus in this bodily fluid remains unknown. Of particular significance is the persistence of virus release in the semen of HIV-infected men under antiretroviral therapy, who otherwise show an undetectable blood viral load. It is therefore considered critical to identify the sources of virus shedding in semen for the more efficient control of HIV transmission. A number of studies indirectly suggest that the free viral particles and infected cells contaminating semen are produced within the male genital tract. Our recent findings indicate HIV infection of several semen-producing organs, including the testis (which represents a pharmacological sanctuary for several antiretroviral drugs), thus reinforcing the hypothesis of the local origin of the seminal contamination. Whether one or several of these organs constitute a viral reservoir seeding semen despite antiviral therapies, remains to be determined. In addition, the detection of virus within the testicular germ cells should be taken into account in the context of assisted reproductive techniques using these cells from HIV positive men.

Abstract
OBJECTIVE Assisted reproduction techniques can minimize the risk of HIV female contamination when the male partner is HIV-infected. The aim of this study was to investigate the efficiency of sperm washing and intrauterine insemination (IUI) in these couples. STUDY DESIGN Retrospective comparative study. Eighty-four HIV-1 serodicordant couples underwent 294 IUI. The control group was composed of 90 couples (320 IUI cycles) with donor sperm. Spermatozoa from HIV-1 infected male partner were prepared and tested for HIV-1 according to sperm washing method. Spermatozoa from HIV-1 and donor male were frozen before IUI. IUI were performed after ovarian stimulation. Main outcomes measures were pregnancy rate per cycle and baby take-home rate per couples. RESULTS Although the pregnancy rate and baby take-home rate were higher in IUI with sperm washing than in IUI using donor sperm (18.0 versus 14.7 and 52.4 versus 41.1, respectively), the differences were not statistically significant. In serodiscordant couples, blood estradiol levels under ovarian stimulation and total motile sperm inseminated were a determining factor in achieving pregnancy. No female HIV-1 contamination occurred. CONCLUSION This study demonstrates that sperm washing and IUI are highly effective in enabling serodiscordant couples with an HIV-1 infected male partner to have a child.

Abstract
Data on the concentrations of didanosine (ddI) and tenofovir (TFV) in seminal plasma are sparse. Subtherapeutic drug concentrations within the lumen of the male genital tract may have implications for selection and transmission of drug-resistant HIV strains. On the other hand, sufficient penetration of these drugs into the male genital tract has potential toxic effects on the spermatozoa and their precursors. In the current study, the authors obtained paired semen and blood samples at variable time points after drug intake from 30 HIV-1-infected patients using a ddI (n = 15) or ddI + TFV (n = 15) containing an antiretroviral regimen. Didanosine and TFV concentrations were measured in seminal and blood plasma and semen quality was assessed. Both ddI and TFV penetrated well into seminal plasma. Whereas blood plasma ddI concentrations dropped to near or below the lower limit of quantification of 0.017 microg/mL 9 hours after drug intake, the ddI concentration in seminal plasma remained detectable during the whole dosing interval with a median of 0.20 and 0.21 microg/mL in the ddI and ddI + TFV groups, respectively. Tenofovir was detectable during the whole dosing interval in both blood and seminal plasma with a median concentration of 0.12 and 0.25 microg/mL, respectively, and a median seminal-to-blood-plasma ratio of 3.3. Semen quality was within the normal range according to the criteria of the World Health Organization, except for the percentage of progressively motile sperm, which was low in both groups of patients. The authors conclude that ddI and TFV penetrate well into seminal plasma and that the reduced sperm motility deserves further study.

Abstract
Objectives To assess the prevalence of abnormal testosterone and gonadotropin values in HIV-infected men before and after 2 years of combination antiretroviral therapy (cART). Design Multicentre cohort of HIV-infected adults. Methods We identified 139 Caucasian antiretroviral-naive male patients who started zidovudine/ lamivudine-based cART that was virologically successful over a 2 year period. Ninety-seven were randomly chosen and plasma hormone determinations of free testosterone (fT) and luteinizing hormone (LH) at baseline and after 2 years of cART were evaluated. Results At baseline 68 patients (70%) had subnormal fT levels. In these, LH levels were low in 44%, normal in 47% and high in 9%. There was a trend for an association between lower CD4+ T-cell counts and hypogonadism. Most participants had normal FSH levels. No significant changes of fT, LH and FSH levels were observed after 2 years of cART. Conclusions Low fT levels, mainly with normal or low LH levels and thus indicating secondary hypogonadism, are found in the majority of HIV-infected men and do not resolve during 2 years of successful cART.

Abstract
We examined the efficacy and effect of HAART in HIV-1-infected men confronted with assisted fertilization procedures. We showed that HAART did not always reduce the HIV-1-RNA level in blood and semen compartments, and that a significant upward shift in mitochondrial DNA was observed in spermatozoa from a HAART-treated patient group compared with spermatozoa from HAART-untreated or HIV-1-uninfected groups (P < 0.001). These findings emphasize the negative role of HAART, but not of HIV-1 infection, in determining semen alterations.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-seropositive males can now father children safely, avoiding transmission risks to the mother and the children using sperm washing and nested PCR (nPCR) techniques. Nevertheless, we still lack enough data to determine the reasons why approximately 10% of the performed sperm washes remain positive, thus forcing the repetition of the treatment. Semen quality in infected males is also essential to these procedures. We aimed to determine the predictive value of the semen parameters, sperm washing procedure and the infection status for the post-wash viral positivity, as well as the correlation between the semen and the disease features. METHODS Semen characteristics were evaluated in 136 samples provided from 125 males. We also included a control group of 125 males matched by age and length of sexual abstinence. At the time of semen retrieval, 70 of them were infected with HIV (45 also with HCV, 64.3%), and 55 of them with HCV alone. nPCR for viral detection was performed in each sample. RESULTS Thirteen out of 136 (9.5%) of the samples were positive for one or more viral detections (HIV RNA, HIV DNA and HCV RNA, when needed). From a total of 240 nPCR viral analyses, 16 were positive (6.6%). None of the seminal parameters were adequate to predict post-wash results, nor was a positive result dependent on the volumes used in the semen wash. A positive correlation was found between post-wash progressive motility and CD4 blood levels, as well as a negative correlation between progressive motility and time of evolution of the disease in HIV-infected males. CONCLUSIONS Semen analysis, according to the World Health Organization criteria, of HIV- and HCV-affected patients showed no differences from that of non-infected males. Moreover, low CD4 blood levels, and a long evolution of the disease do not negatively affect sperm motility.

Abstract
Semen samples from a donor who seroconverted for human immunodeficiency virus type 1 (HIV-1) during the period that he was donating at our clinic were stored before and after infection. Semen analysis was done on all of these samples before cryopreservation. Retrospectively, both qualitative and quantitative HIV-1 testing was performed on the cryopreserved semen samples to determine the time of primary HIV-1 infection. After HIV-1 infection, semen volume, sperm motility and the percentage of spermatozoa with normal morphology were reduced compared with the same parameters before HIV-1 infection. HIV-1 RNA was intermittently detectable in semen. HIV-1 infection led to a reduction in semen volume, sperm motility and normal sperm morphology in this donor. However, the clinical significance of these findings is unclear. A longitudinal cohort study on the effects of HIV-1 infection on semen quality is necessary to confirm these findings.

Abstract
BACKGROUND This is the first study to assess the outcome of sperm washing and intrauterine insemination (IUI) cycles in human immunodeficiency virus-positive (HIV(+)) men to determine any predictors of success, as well as evaluating the effect of HIV on sperm parameters. METHODS Semen characteristics were evaluated in 106 HIV(+) men and a control group of 234 HIV(-) men, and the effect of markers of HIV disease assessed. Age, stimulation regime, sperm parameters, markers of HIV disease and the use of anti-retrovirals were assessed as predictors of the outcome of sperm washing/IUI cycles in the HIV(+) men. RESULTS Ejaculate volume, sperm concentration, total count, progressive motility and normal morphology were all significantly higher in the control group compared to the HIV(+) men (P<0.05). A significant positive correlation was observed between CD4 count and sperm concentration, total count, motility, progressive motility type 'a'+'b' and post-preparation concentration and a significant negative correlation with normal sperm morphology of both raw and post-preparation samples. No correlation was observed between viral load (VL), years since diagnosis, use of anti-retrovirals or duration of use and any sperm parameter. The only factors that significantly improved IUI outcome were a VL <1000 copies/ml and the use of anti-retrovirals. CONCLUSIONS These data demonstrate that sperm parameters are significantly impaired by the presence of HIV infection and in particular correlate with CD4 count. Undetectable VL and the use of anti-retrovirals improve the outcome of IUI/sperm washing in HIV(+) men.

Abstract
With the development of combination therapies and their use for the treatment of the human immunodeficiency virus (HIV), the health and life expectancy of HIV-positive patients has improved significantly. As a result, HIV-discordant couples are looking to a future that involves starting a family. However, the potential risks of exposing HIV-infected sperm to oocytes are still being assessed. This article outlines the clinical detection of HIV in semen samples, the relationships between HIV and semen parameters, and HIV-sperm and oocyte interactions. It also considers the implications of introducing exogenous genetic material into an oocyte via intracytoplasmic sperm injection (ICSI) and the possible implications of this for assisted reproduction.

Abstract
This review describes the various viruses identified in the semen and reproductive tracts of mammals (including humans), their distribution in tissues and fluids, their possible cell targets, and the functional consequences of their infectivity on the reproductive and endocrine systems. The consequences of these viral infections on the reproductive tract and semen can be extremely serious in terms of organ integrity, development of pathological and cancerous processes, and transmission of diseases. Furthermore, of essential importance is the fact that viral infection of the testicular cells may result not only in changes in testicular function, a serious risk for the fertility and general health of the individual (such as a fall in testosteronemia leading to cachexia), but also in the possible transmission of virus-induced mutations to subsequent generations. In addition to providing an exhaustive account of the data available in these domains, this review focuses attention on the fact that the interface between endocrinology and virology has so far been poorly explored, particularly when major health, social and economical problems are posed. Our conclusions highlight the research strategies that need to be developed. Progress in all these domains is essential for the development of new treatment strategies to eradicate viruses and to correct the virus-induced dysfunction of the endocrine system.

Abstract
The AIDS virus of cat species, feline immunodeficiency virus (FIV), has been used extensively as an animal model of HIV-1 infection. This felid lentivirus shares many molecular and biochemical traits with HIV-1 and causes similar immunologic and clinical perturbations, most notably CD4+ cell loss, impaired cell-mediated immunity and increased susceptibility to opportunistic pathogens. Previous reports have shown that FIV is transmitted horizontally by biting and vertically in utero and through nursing. Our objective was to determine whether FIV could be venereally transmitted in domestic cats. In the first experiment, susceptibility of the female reproductive tract to mucosal transmission of the FIV isolate, NCSU1, was demonstrated via intravaginal inoculation with infected cultured cells. We next identified virus in electroejaculates from asymptomatic, chronically FIV-NCSU1-infected, adult males. A fragment of FIV gag provirus DNA was detected by nested polymerase chain reaction (PCR) in nonfractionated seminal cells and in swim-up sperm preparations. Additionally, replication-competent virus was isolated from cell-free seminal plasma and seminal cells by co-cultivation with a feline CD4+ T-cell line. In the third study, queens were artificially inseminated via an intrauterine laparoscopic technique with electroejaculates from FIV-NCSU1-infected males. Of six inseminations carried out with fresh semen, three resulted in infection of queens. Lastly, immunohistochemical studies identified potential virus target cell populations in normal female reproductive tissues. In conclusion, these experiments indicate that FIV infection in domestic cats may provide a unique small animal model of sexual transmission of HIV-1.

Abstract
Complete semen analyses including computer-assisted sperm motility and morphology assessments were performed to determine if semen and sperm differed between HIV-seropositive men and fertile controls, or differed with symptoms, or CD4+ peripheral cell count categories. Previous studies included small numbers of men and presented conflicting conclusions. Two hundred and fifty non-vasectomized HIV-seropositive men and 38 fertile controls each provided one semen sample. Non-parameteric statistics were used to analyse both continuous and nominal data. Fertile men had significantly greater semen volume, sperm concentration, percent motility, percent rapid and linear motility and total strictly normal spermatozoa than HIV seropositive men. Neither total number nor subtypes of leukocytes in semen differed between the two groups. Among the HIV seropositive men, significant differences in semen analyses were found between CD4+ cell count, clinical, and AIDS categories. Lower CD4+ cell counts (< 200 mm-3) were associated with significantly lower percent motility, percent normal sperm morphology by strict criteria, significantly more spermatids in semen, and higher percentages of teratozoospermia, oligoasthenoteratozoospermia and leukocytospermia. Healthier men, based on clinical categories, had significantly more normal shaped spermatozoa and fewer had azoospermia, oligoasthenoteratozoospermia or leukocytospermia. Many HIV-seropositive men have normal semen analyses, but as the disease progresses more defects are found, particularly in strict criteria sperm morphology.

Abstract
We have undertaken an analysis of semen from HIV infected men with regard to sperm counts and motility, non-spermatozoal cells, and viral nucleic acid. Regression analysis showed that sperm concentration and motility were positively associated with blood CD4 cell count. By contrast, non-spermatozoal cell concentration (round cells) was inversely related to CD4 count. Extracellular HIV RNA was detected in the majority of semen samples and proviral DNA in a minority. Percoll gradient washing of 12 semen samples yielded six samples containing adequate sperm concentration for analysis. This washing procedure reduced prewash extracellular RNA to below detectable limits in all cases; proviral DNA present in two of the six prewash samples was also reduced to below detectable limits after washing. We conclude that semen washing before artificial insemination may reduce the risk of HIV transmission from an infected man to an uninfected woman. However, further evidence from prospective analyses of such an approach is required.

Abstract
OBJECTIVE To investigate the presence of human papillomavirus (HPV) in human sperm cells and to evaluate potential effects of HPV on the sperm functions. DESIGN A descriptive clinical study. PATIENT(S) Specimens of semen were collected from 24 randomly selected patients who attended the fertility clinics at Chang Gung Memorial Hospital. MAIN OUTCOME MEASURE(S) The presence of HPV DNA and RNA were examined by polymerase chain reaction. Semen quality and sperm cell function were analyzed by computer-aided autoanalyzer. RESULT(S) Human papillomavirus type 16 DNA and RNA were found in 6 (25%) and 2 (8%) of the sperm cells specimens, respectively. Human papillomavirus type 18 DNA and RNA were present in 11 (46%) and 5 (21%) of the same sperm cells specimens, respectively. Incidence of asthenozoospermia among patients infected with either HPV was significantly higher than in those without HPV in their sperm cells (75% versus 8%). Although performance of curvilinear velocity, straight-line velocity, and mean amplitude of lateral head displacement was significantly lower in HPV-infected specimens, the differences of linearity, beat cross frequency, and straightness were not statistically significant. CONCLUSION(S) These results suggest that human papillomavirus can be found in human sperm cells and that certain HPV-specific genes are actively transcribed. Sperm motility parameters seem to be affected by the presence of HPV in the sperm cells, and also the incidence of asthenozoospermia may be associated with HPV infection.
