Abstract
Although placental small extracellular vesicles (sEVs) are extensively studied in the context of pregnancy, little is known about their role during viral congenital infection, especially at the beginning of pregnancy. In this study, we examined the consequences of human cytomegalovirus (hCMV) infection on sEVs production, composition, and function using an immortalized human cytotrophoblast cell line derived from first trimester placenta. By combining complementary approaches of biochemistry, electron microscopy, and quantitative proteomic analysis, we showed that hCMV infection increases the yield of sEVs produced by cytotrophoblasts and modifies their protein content towards a potential proviral phenotype. We further demonstrate that sEVs secreted by hCMV-infected cytotrophoblasts potentiate infection in naive recipient cells of fetal origin, including human neural stem cells. Importantly, these functional consequences are also observed with sEVs prepared from an ex vivo model of infected histocultures from early placenta. Based on these findings, we propose that placental sEVs could be important actors favoring viral dissemination to the fetal brain during hCMV congenital infection.

Abstract
Usutu virus (USUV) is a neurotropic mosquito-borne flavivirus that has dispersed quickly in Europe these past years. This arbovirus mainly follows an enzootic cycle involving mosquitoes and birds, but can also infect other mammals, causing notably sporadic cases in humans. Although it is mainly asymptomatic or responsible for mild clinical symptoms, USUV has been associated with neurological disorders, such as encephalitis and meningoencephalitis, highlighting the potential health threat of this virus. Among the different transmission routes described for other flaviviruses, the capacity for some of them to be transmitted vertically has been demonstrated, notably for Zika virus or West Nile virus, which are closely related to USUV. To evaluate the ability of USUV to replicate in the placenta and gain access to the fetus, we combined the use of several trophoblast model cell lines, ex vivo human placental explant cultures from first and third trimester of pregnancy, and in vivo USUV-infected pregnant mice. Our data demonstrate that human placental cells and tissues are permissive to USUV replication, and suggest that viral transmission can occur in mice during gestation. Hence, our observations suggest that USUV could be efficiently transmitted by the vertical route.

Abstract
We investigated the effects of dengue virus (DENV) on semen using samples collected 7, 15, 30, 60, and 90 days after symptom onset from 10 infected volunteers on Réunion Island. We assessed characteristics of semen and reproductive hormones and isolated motile spermatozoa from semen. We assayed semen for DENV using reverse transcription PCR and searched for DENV RNA by virus isolation in Vero E6 cell cultures. Four volunteers had >1 DENV RNA-positive semen samples; 2 volunteers had DENV RNA–positive semen at day 15 and 1 at day 30. No motile sperm were DENV positive. After exposure to positive semen, few Vero E6 cells stained positive for DENV antigens, indicating low levels of replicative virus. We found DENV had shorter duration in semen than in blood. These findings support the possibilities that DENV is sexually transmissible for a short period after acute dengue illness and that acute dengue induces reversible alterations in sperm.

Abstract
Extracellular vesicles (EVs) have increasingly been recognized as key players in a wide variety of physiological and pathological contexts, including during pregnancy. Notably, EVs appear both as possible biomarkers and as mediators involved in the communication of the placenta with the maternal and fetal sides. A better understanding of the physiological and pathological roles of EVs strongly depends on the development of adequate and reliable study models, specifically at the beginning of pregnancy where many adverse pregnancy outcomes have their origin. In this study, we describe the isolation of small EVs from a histoculture model of first trimester placental explants in normal conditions as well as upon infection by human cytomegalovirus. Using bead-based multiplex cytometry and electron microscopy combined with biochemical approaches, we characterized these small EVs and defined their associated markers and ultrastructure. We observed that infection led to changes in the expression level of several surface markers, without affecting the secretion and integrity of small EVs. Our findings lay the foundation for studying the functional role of EVs during early pregnancy, along with the identification of new predictive biomarkers for the severity and outcome of this congenital infection, which are still sorely lacking.

Abstract
BACKGROUND We showed that in men with a constitutional chromosomal abnormality, DNA fragmentation was significantly higher in chromosomally unbalanced spermatozoa than in spermatozoa with a normal or balanced chromosomal content. These results could be explained by a phenomenon already described in infertile men: abortive apoptosis. OBJECTIVES To determine whether magnetic-activated cell separation could select spermatozoa with lower levels of DNA fragmentation and unbalanced chromosome content in men carrying a structural chromosomal abnormality. MATERIALS AND METHODS The spermatozoa of ten males with a chromosomal rearrangement were separated into two populations using magnetic-activated cell separation (annexin V (-) and annexin V (+) fractions), in order to study meiotic segregation by fluorescence in situ hybridization, the percentage of spermatozoa with an externalization of phosphatidylserine by annexin V staining and DNA fragmentation by TdT-mediated dUTP nick-end labeling on the whole ejaculate and on selected spermatozoa in the same patient. RESULTS For all patients, the percentage of spermatozoa with externalization of phosphatidylserine decreased in the annexin V (-) fraction and increased in the annexin V (+) fraction as compared to the frozen-thawed semen sample. The rates of DNA fragmentation were statistically much lower in the annexin V (-) fraction when compared to the rate before magnetic-activated cell separation for all but one patient. Conversely, we observed a statistically significantly higher rate of DNA fragmentation in the annexin V (+) fraction for six patients. After magnetic-activated cell separation, there was a significant increase of normal/balanced spermatozoa in the fraction of annexin V (-) for all patients. Conversely, we observed a significant decrease in the fraction of annexin V (+) for seven patients. DISCUSSION AND CONCLUSIONS Magnetic-activated cell separation is a promising tool for increasing the selection of healthy spermatozoa, with a decrease in the number of spermatozoa with externalization of phosphatidylserine, DNA fragmentation, and chromosome unbalance, for use in assisted reproductive technologies such as intracytoplasmic sperm injection for males with a chromosomal structural abnormality.

Abstract
RESEARCH QUESTION Anti-sperm antibodies (ASA) have been shown to reduce male fertility but consensus about the precise situations in which tests should be carried out are lacking. In infertility investigations, should the mixed antiglobulin reaction (MAR) test be a first-line test? Should it be carried out systematically before assisted reproductive technology (ART)? What are the risk factors for ASA? DESIGN All infertile patients (n = 1364) were tested with SpermMar (modified MAR test) between July 2013 and June 2017. Intra-patient variability of the MAR test was also assesed by comparing two tests within the same year in selected patients (n = 101). RESULTS The main factor that influenced the percentage of ASA was the presence or absence of sperm agglutination. In the presence of agglutinations, 27 out of 72 (37.5%) patients were positive for ASA compared with 33 out of 1292 (2.6%) in the absence of agglutinations (P < 0.0001). When one risk factor was present (spontaneous sperm agglutination, history of scrotal trauma or inguinal surgery), 33 out of 179 (18.44%) tests were positive for ASA (≥50% coated spermatozoa), whereas only 27 out of 1242 (2.2%) were positive when no risk factor was present (P < 0.0001). CONCLUSIONS ASA detection should not be systematically recommended in investigations of fertility status and before ART but reserved for when sperm agglutination is found during conventional sperm examination, or if the patient has a history of scrotal trauma or has undergone inguinal surgery.

Abstract
Background More and more HIV-1-infected men on effective antiretroviral treatment (ART) have unprotected sex in order to procreate. The main factor influencing transmission is seminal HIV shedding. While the risk of HIV transmission is very low, it is difficult to assess in individuals. Nevertheless, it should be quantified. Results We retrospectively analysed seminal plasma HIV-1 shedding by 362 treated HIV-infected men attending a medically assisted reproduction centre (1998–2013) in order to determine its frequency, the impact of the antiretroviral regimen on HIV shedding, and to identify shedding patterns. The HIV-1 virus loads in 1396 synchronized blood and semen samples were measured, and antiretroviral treatment, biological and epidemiological data were recorded. We detected isolated HIV-1 shedding into the seminal plasma in 5.3% of patients on efficient antiretroviral treatment, but there was no association with the HIV antiretroviral drug regimen or the CD4 cell count. These men had undergone more regimen changes since treatment initiation and had been on the ongoing drug regimen longer than the non-shedding men. The patterns of HIV seminal shedding among patients with undetectable HIV blood virus load varied greatly. HIV seminal shedding can occur as long as 5 years after starting antiretroviral treatment. Conclusions The seminal HIV load was used to monitor risk for infertile HIV-infected patients on an assisted reproductive technology program. This can still be recommended for patients who recently (6 months) started ART, or those with a poor history of adherence to ART but may also be usefull for some patients during counselling. Residual HIV seminal shedding is probably linked to breaks in adherence to antiretroviral treatment but local genital factors cannot be ruled out.

Abstract
Background Treatment of differentiated thyroid cancer usually consists of a total thyroidectomy followed by one or several courses of radioiodine (131I). 131I is known to have deleterious effects on radiation sensitive tissues and irradiation to the testes has been shown after its administration. We investigated effects of such treatment on sperm DNA in a patient with differentiated thyroid carcinoma. Methods The patient, a 32-year-old male with differentiated thyroid carcinoma treated by total thyroidectomy and radioiodine therapy, performed 6 semen samples in total, 3 for sperm banking and 3 for semen exploration, that were analysed for classic semen parameters. DNA integrity was analysed by flow cytometry: sperm DNA fragmentation index (DFI) and high DNA stainability (HDS) were analyzed by sperm chromatin structure assay, DNA fragmentation was analyzed by terminal deoxynucleotidyl transferase dUTP nick end labeling assay. Results Moderate oligozoospermia was observed as early as 3 months after a first dose of 131I and became severe at 5 months. Total sperm count was reduced up to 12 months after the second dose of 131I. Sperm DFI was increased 3.25 months after the first dose of 131I. All parameters returned to normal values 28 months after the second 131I dose. Conclusions Treatment with 131I induces alterations in sperm chromatin as well as in sperm parameters a short time (3 months) after a first dose of 131I with persistence of sperm alterations until 12 months after a second dose. Sperm banking should be recommended before treatment.

Abstract
OBJECTIVE To determine consequences of lymphoma treatments on sperm characteristics and sperm DNA, and to evaluate predictors of sperm recovery. DESIGN Multicenter prospective longitudinal study of patients analyzed before treatment and after 3, 6, 12, and 24 months. SETTING University hospitals. PATIENT(S) Seventy-five Hodgkin lymphoma and non-Hodgkin lymphoma patients and a control group of 257 fertile men. INTERVENTION(S) Semen analyses, and sperm DNA and chromatin assessments. MAIN OUTCOME MEASURE(S) Comparisons of sperm characteristics before and after treatment. RESULT(S) Patients already had altered sperm characteristics before lymphoma treatment, with no identified risk factor. Sperm count, total sperm count, motility, and vitality decreased after treatment, with lowest values at 3 and 6 months. Twelve months after treatment, mean sperm count recovered to pretreatment values after doxorubicin, bleomycin, vinblastine, darcarbacine (ABVD) or ABVD+radiotherapy, but not after doxorubicin, cyclophosphamide, vincristine, prednisone (CHOP) or mechlorethamine, oncovin, procarbazine, prednisone (MOPP) chemotherapies. It was noteworthy that 7% of patients remained azoospermic at 24 months. After 24 months, Kaplan-Meier estimates showed that more than 90% of patients will recover normal sperm count after ABVD or ABVD+radiotherapy vs. 61% for CHOP chemotherapies. In multivariate analyses including diagnosis and treatment protocol, only pretreatment total sperm count was related to recovery. Compared with a control group, lymphoma patients had higher sperm chromatin alterations and DNA fragmentation before any treatment. After treatment, DNA fragmentation assessed by TUNEL assay and sperm chromatin structure assay decreased from 3 and 6 months, respectively, while remaining higher than in the control group during follow-up. CONCLUSION(S) Lymphoma patients had altered sperm DNA and chromatin before treatment. Lymphoma treatment had damaging effects on spermatogenesis. These data on both the recovery period according to treatment modalities and the pre- and post-treatment chromatin status of sperm are useful tools for counseling patients wishing to conceive.

Abstract
OBJECTIVE To determine the consequences of adjuvant testicular germ cell tumor treatment (TGCT) on sperm characteristics and sperm DNA, and to evaluate the predictors of sperm recovery. DESIGN Multicenter prospective longitudinal study of patients analyzed before treatment and after 3, 6, 12, and 24 months. SETTING University hospitals. PATIENT(S) One hundred twenty-nine volunteer TGCT patients and a control group of 257 fertile men. INTERVENTION(S) Routine semen analyses, sperm DNA, and chromatin assessments. MAIN OUTCOME MEASURE(S) Comparisons of mean sperm characteristics before and after treatment, with sperm recovery analyzed by the Kaplan-Meier method. RESULT(S) The quantitative and qualitative sperm characteristics decreased after treatment, with lowest values at 3 and 6 months and with variations according to treatment type. The mean total sperm count recovered to pretreatment values at 12 months after treatment after two or fewer bleomycin, etoposide, and cisplatin (BEP) cycles, but not after radiotherapy or more than two BEP cycles. Only the treatment modalities and pretreatment sperm production were related to recovery of the World Health Organization reference sperm values. An increased proportion of patients had elevated high sperm DNA stainability at 6 months after radiotherapy. CONCLUSION(S) Adjuvant treatments for testicular germ cell tumor have drastic effects on spermatogenesis and sperm chromatin quality. These new data on both the recovery period according to treatment modalities and the post-treatment chromatin status of sperm are useful tools for counseling patients wishing to conceive.

Abstract
The semen plasma virus load is measured to ensure the safety of sperm processing during medically assisted procreation (MAP) for couples with a human immunodeficiency virus type 1 (HIV-1)-infected man. A practical, automated protocol using the COBAS Ampliprep CAP/CTM kit in the COBAS TaqMan96 system was developed to measure the HIV-1 load in semen plasma samples. HIV-1 was detected in 13.4% of the semen samples processed at our MAP center. Of the eight patients having a detectable semen HIV-1 load, five had no detectable virus in their blood plasma. This highlights the residual risk of HIV-1 transmission during unprotected intercourse and raises the question of the possible consequences of ineffective highly active antiretroviral therapy in the genital tract.

Abstract
OBJECTIVE To report the effects of ribavirin plus pegylated interferon on semen parameters and sperm DNA integrity in a man given treatment for hepatitis C. DESIGN Case report. SETTING University-affiliated teaching hospital. INTERVENTION(S) None. PATIENT(S) A 37-year-old man given treatment with ribavirin and pegylated interferon for hepatitis C. MAIN OUTCOME MEASURE(S) Semen parameters (sperm count, motility, round cells), sperm protamination state measured by sperm chromatin structure assay, and sperm DNA fragmentation measured by terminal uridine nick-end labeling assay. RESULT(S) The percentage of progressive spermatozoa and the number of motile sperm per ejaculate decreased during treatment. The round cell/spermatozoa ratio, which reflects spermatogenic abnormality, increased from 2.6% +/- 1.4% to 23.6% +/- 13.0% during treatment and returned to baseline value 4 months later. Moreover, the sperm DNA fragmentation index (as measured by sperm chromatin structure assay) increased very markedly during treatment (from 14.5% before to 69.2% at 7 months of treatment) and remained elevated 8 months later. CONCLUSION(S) This study reports for the first time not only quantitative but also qualitative alterations of spermatogenesis with DNA packaging abnormalities and emphasizes the need for prospective clinical studies. While the results of other studies are awaited, the alterations that persisted 8 months after treatment argue for a longer contraception period after treatment discontinuation in 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
BACKGROUND To date, assisted reproductive technology (ART) with sperm washing is offered to serodiscordant couples with an human immunodeficiency virus-1 (HIV-1) infected male partner in order to have a child while reducing the risk of transmission to the woman. However, ART programmes are not possible if the man is azoospermic. We report here the first birth following intracytoplasmic sperm injection (ICSI) using frozen epididymal spermatozoa obtained after surgical sperm retrieval in a HIV-1 infected man with obstructive azoospermia. METHODS; Sperm obtained by micro-epididymal sperm aspiration was frozen after density gradient preparation and tested for HIV-RNA and DNA. ICSI with frozen sperm was performed. RESULTS A twin pregnancy was obtained following ICSI. Two healthy girls were born. Maternal HIV-1 RNA and HIV-1 serology were negative during pregnancy and at delivery. CONCLUSIONS This case report demonstrates that ART is possible in azoospermic HIV-1 infected men. On the basis of current knowledge, we propose a strategy to reduce HIV-1 transmission risk during sperm retrieval and ICSI in couples where the man is HIV-1 infected and azoospermic.

Abstract
Inconsistent results have been reported for the semen quality in HIV-infected men, due to the biases inherent in some studies. The objective of the present study was to investigate the semen parameters in HIV-1-infected patients and to compare their sperm characteristics with those of a control group of fertile, noninfected men. Factors implicated in semen alterations in HIV-1 patients were also analyzed. HIV-infected men (n=190), of whom 91% were undergoing antiretroviral therapy, and 218 fertile men were studied. Infertility risk factors were recorded and clinical examinations were performed for both groups. Records of history of HIV infection, antiretroviral treatment, and HIV-1 RNA detection in the blood as well as HIV-1 genome detection in the semen were obtained for the infected patients. Semen volumes, percentages of progressive motile spermatozoa, total sperm counts, and polymorphonuclear cell counts were decreased, while the pH values and spermatozoa multiple anomaly indices were increased in HIV-infected patients. Even after adjustment for possible sources of bias, the decreases in semen volume and progressive motility and the increase in pH remained significant. The present study demonstrates sperm motility and ejaculate volume alterations in HIV-1-infected patients, most of whom were receiving antiretroviral therapy. In HIV-1 patients, further longitudinal studies are required to analyze the impact of treatment regimen on sperm parameter alterations.

Abstract
The ability to detect and quantify HIV and HCV genomes is important for checking spermatozoid preparation protocols also known as "sperm washing". But no commercial assay is available. A method was developed for detecting HIV and HCV in semen fractions using the COBAS Ampliprep and COBAS Taqman instruments. It will detect fewer than 200 copies of HIV RNA per ml of semen plasma and fewer than 200 copies/3 x 10(6) semen cells. The sensitivity for HCV is similar at more than 200 IU/ml and below 200 IU/3 x 10(6) semen cells. No inhibitor of PCR amplification was detected. This automated protocol permits a convenient, standardized testing for HIV and HCV in semen. The performance is the same as that of the previous generation of automated assays but the cost and operating time are both reduced.

Abstract
Formation of the epitopes recognized by the rheumatoid arthritis (RA)-specific autoantibodies to citrullinated proteins (ACPA) on filaggrin and on the alpha- and beta-chains of fibrin, their synovial target, requires conversion of their arginyl residues into citrullyl residues, but is also affected by their amino-acyl environment. Using competition with five citrullinated filaggrin-derived peptides bearing major ACPA epitopes, we confirmed the close cross-reactivity between filaggrin and citrullinated fibrin. To identify the sequential epitopes recognized on fibrin by ACPA, 71 citrullinated 15-mer peptides derived from all the sites of the alpha- and beta-chains of fibrin harboring arginyl residues were tested by ELISA using ACPA-positive RA sera exhibiting different reactivity profiles to the five filaggrin peptides. We identified 18 fibrin-derived peptides bearing ACPA epitopes. Regarding the ability of fibrinogen arginyl residues to be citrullinated in vitro, 11 of the peptides likely correspond to in vivo targeted epitopes. Two out of them bear major epitopes and are located in the central globular domain of the protein. In the synovial tissue, fibrin citrullination and ACPA binding could impair fibrin degradation by plasmin. The immunological conflict between ACPA and fibrin could therefore sustain synovial inflammation not only via pro-inflammatory effector mechanisms but also via impairment of fibrinolysis.

Abstract
Human cytomegalovirus (HCMV) infection is well controlled mainly by cytotoxic CD8(+) T lymphocytes (CTL) directed against the matrix protein pp65 despite the numerous immune escape mechanisms developed by the virus. Dendritic cells (DCs) are key antigen-presenting cells for the generation of an immune response which have the capacity to acquire antigens via endocytosis of apoptotic cells and thus present peptides to major histocompatibility complex class I-restricted T cells. We examined whether this mechanism could contribute to the activation of anti-pp65 CTL. In this study, we show that infection by HCMV AD169 induced sensitization of MRC5 fibroblasts to tumor necrosis factor alpha-mediated apoptosis very early after virus inoculation and that pp65 contained in apoptotic cells came from the delivery of the matrix protein into the cell. We observed that immature DCs derived from peripheral monocytes were not permissive to HCMV AD169 infection but were able to internalize pp65-positive apoptotic infected MRC5 cells. We then demonstrated that following exposure to these apoptotic bodies, DCs could activate HLA-A2- or HLA-B35-restricted anti-pp65 CTL, suggesting that they acquired and processed properly fibroblast-derived pp65. Together, our data suggest that cross-presentation of incoming pp65 contained in apoptotic cells may provide a quick and efficient way to prime anti-HCMV CD8(+) T cells.
