Necrozoospermia is a condition found in 0.2%-0.4% of male infertility cases. The causes of necrozoospermia are multiple: they can be related to testicular and/or post-testicular damage. Additionally, these causes most often involve the production of reactive oxygen species (ROS) and/or sperm DNA fragmentation (SDF) which can reduce the chances of spontaneous pregnancy or affect the outcome of assisted reproductive technologies.To focus on potential etiologies of necrozoospermia, its diagnosis and its therapeutic management especially before the employment of ICSI.Authors searched PubMed/Medline, Web of Science, Cochrane Library, Google and Institutional websites for medical subheading terms and free text words referred to "necrozoospermia", "sperm vitality", "sperm viability", SDF and "ICSI".We identified 12 main etiologies of necrozoospermia responsible for either a decrease of sperm vitality, a mild, a moderate or a severe necrozoospermia. In case of a confirmed decreased vitality, a thorough check-up should be conducted and if available, etiological treatment should be proposed. Therapeutic management could also include repeated ejaculations, drug treatments, the use of ICSI with ejaculated or surgically extracted spermatozoa in case of a non-treatable necrozoospermia.The potential causes of necrozoospermia should be investigated because many of them could be corrected, thus avoiding the use of ICSI. Moreover, if ICSI procedure remains necessary, the therapeutic management of necrozoospermia could also improve the chances of success by reducing oxidative stress and/or SDF.

Among the most prevalent sources of biodiversity declines, Artificial Light At Night (ALAN) is an emerging threat to global biodiversity. Much knowledge has already been gained to reduce impacts. However, the spatial variation of ALAN effects on biodiversity in interaction with landscape composition remains little studied, though it is of the utmost importance to identify lightscapes most in need of action. Several studies have shown that, at local scale, tree cover can intensify positive or negative effects of ALAN on biodiversity, but none have – at landscape scale – studied a wider range of landscape compositions around lit sites. We hypothesized that the magnitude of ALAN effects will depend on landscape composition and species’ tolerance to light. Taking the case of insectivorous bats because of their varying sensitivity to ALAN, we investigated the species-specific activity response to ALAN. Bat activity was recorded along a gradient of light radiance. We ensured a large variability in landscape composition around 253 sampling sites. Among the 13 bat taxa studied, radiance decreased the activity of two groups of the slow-flying gleaner guild (Myotis and Plecotus spp.) and one species of the aerial-hawking guild (Pipistrellus pipistrellus), and increased the activity of two species of the aerial-hawking guild (Pipistrellus kuhlii and Pipistrellus pygmaeus). Among these five effects, the magnitude of four of them was driven by landscape composition. For five other species, ALAN effects were only detectable in particular landscape compositions, making the main effect of radiance undetectable without account for interactions with landscape. Specifically, effects were strongest in non-urban habitats, for both guilds. Results highlight the importance to prioritize ALAN reduction efforts in non-urban habitats, and how important is to account for landscape composition when studying ALAN effects on bats to avoid missing effects.

P450 oxidoreductase deficiency (PORD) is an autosomal recessive disease caused by bi-allelic mutations of the POR gene. It is responsible for decreased activity of several P450 enzymes including CYP21A2, CYP17A1 and CYP19A1 that are involved in adrenal and/or gonadal steroidogenesis. PORD is typically diagnosed in neonates and children with ambiguous genitalia and/or skeletal abnormalities. Adult-onset PORD has been very seldom reported and little is known about the optimal way to investigate and treat such patients. In this series, we report five women aged 19-38 years, who were referred for unexplained oligo-/amenorrhea and/or infertility. Genetic testing excluded 21-hydroxylase deficiency (21OH-D), initially suspected due to increased 17-hydroxyprogesterone (17-OHP) levels. Extensive phenotyping, steroid profile by mass spectrometry, pelvic imaging and next-generation sequencing of 84 genes involved in gonadal and adrenal disorders were performed in all patients. In Vitro Fertilization (IVF) followed by frozen embryo transfer under glucocorticoid suppression therapy was performed in two patients. All patients had oligomenorrhea or amenorrhea. None had hyperandrogenism. Low-normal serum estradiol (E2) and testosterone levels contrasted with chronically increased serum progesterone (P) and 17-OHP levels, which further increased after ACTH administration. Despite excessive P, 17OH-P and 21-deoxycortisol rises after ACTH stimulation suggesting non-classic 21-hydroxylase deficiency, CYP21A2 sequencing did not support this hypothesis. Basal serum cortisol levels were low to normal, with inadequate response to ACTH in some women, suggesting partial adrenal insufficiency. Pelvic imaging revealed bilateral ovarian macrocysts in all women. All patients were found to harbor rare bi-allelic POR mutations classified as pathogenic according to American College of Medical Genetics standards. IVF was performed in two women after retrieval of a normal oocyte number despite very low E2 levels during controlled ovarian hyperstimulation. Frozen embryo transfer under glucorticoid suppression therapy led to successful pregnancies. These observations suggest that diagnosis of PORD must be considered in infertile women with chronically elevated P and 17OH-P levels and ovarian macrocysts. Differentiation of this entity from non-classic 21-hydroxylase deficiency is important, as the multiple enzyme deficiency requires a specific management. Successful fertility induction is possible by IVF, providing that P levels be sufficiently suppressed by glucocorticoid therapy prior to implantation.

The relationship between serum anti-Mullerian hormone (AMH) levels, body mass index (BMI) and related metabolic factors were investigated in women with polycystic ovary syndrome (PCOS). A total of 691 women aged between 18 and 35 years, referred to the Department of Gynaecological Endocrinology at the University Hospital of Lille between 2009 and 2014 were included: 137 controls and 554 women with PCOS. Mean serum AMH levels were slightly but significantly lower in women with PCOS who were overweight or obese (BMI ≥25) compared with women of normal weight (BMI

STUDY QUESTION Can cytochrome P450 oxidoreductase deficiency (PORD) be revealed in adult women with menstrual disorders and/or infertility? SUMMARY ANSWER PORD was biologically and genetically confirmed in five adult women with chronically elevated serum progesterone (P) who were referred for oligo-/amenorrhea and/or infertility. WHAT IS KNOWN ALREADY PORD is an autosomal recessive disease typically diagnosed in neonates and children with ambiguous genitalia and/or skeletal abnormalities. It is responsible for the decreased activity of several P450 enzymes, including CYP21A2, CYP17A1 and CYP19A1, that are involved in adrenal and/or gonadal steroidogenesis. Little is known about the optimal way to investigate and treat patients with adult-onset PORD. STUDY DESIGN, SIZE, DURATION In this series, we report five adult females who were evaluated in three tertiary endocrine reproductive departments between March 2015 and September 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS Five women aged 19–38 years were referred for unexplained oligo-/amenorrhea and/or infertility. Genetic testing excluded 21-hydroxylase deficiency (21OH-D), initially suspected due to the increased 17-hydroxyprogesterone (17-OHP) levels. Extensive phenotyping, steroid profiling by mass spectrometry, pelvic imaging and next-generation sequencing of 84 genes involved in gonadal and adrenal disorders were performed in all patients. IVF followed by frozen embryo transfer (ET) under glucocorticoid suppression therapy was performed for two patients. MAIN RESULTS AND THE ROLE OF CHANCE All patients had oligomenorrhea or amenorrhea. None had hyperandrogenism. Low-normal serum estradiol (E2) and testosterone levels contrasted with chronically increased serum P and 17-OHP levels, which further increased after adrenocorticotrophic hormone (ACTH) administration. Despite excessive P, 17OH-P and 21-deoxycortisol rise after ACTH stimulation suggesting non-classic 21OH-D, CYP21A2 sequencing did not support this hypothesis. Basal serum cortisol levels were low to normal, with inadequate response to ACTH in some women, suggesting partial adrenal insufficiency. All patients harbored rare biallelic POR mutations classified as pathogenic or likely pathogenic according to the American College of Medical Genetics and Genomics standards. Pelvic imaging revealed bilateral ovarian macrocysts in all women. IVF was performed for two women after retrieval of a normal oocyte number despite very low E2 levels during ovarian stimulation. Frozen ET under glucocorticoid suppression therapy led to successful pregnancies. LIMITATIONS, REASONS FOR CAUTION The number of patients described here is limited and these data need to be confirmed on a larger number of women with non-classic PORD. WIDER IMPLICATIONS OF THE FINDINGS The diagnosis of PORD must be considered in infertile women with chronically elevated P and 17OH-P levels and ovarian macrocysts. Differentiation of this entity from non-classic 21OH-D is important, as the multiple enzyme deficiency requires a specific management. Successful fertility induction is possible by IVF, providing that P levels be sufficiently suppressed by glucocorticoid therapy prior to implantation.

The prevalence of ovulation disorder (OD) is 3-fold higher in obese than normal-weight women. Most ODs are associated with concomitant polycystic ovary syndrome (PCOS), but obesity by itself can cause OD, through mechanisms that remain poorly documented. The literature on obese non-PCOS women with OD is sparse. The aim of the present study was to analyze a population of obese non-PCOS women with OD to shed further light on the mechanism of ovulation disorder.This retrospective observational study of infertile obese women without PCOS compared a control group without OD (n=45) to a study group with OD (n=30) (OD group). Clinical, hormonal, and ultrasound characteristics were collected between cycle days 2 and 5. Women older than 37 years and women with PCOM (polycystic ovarian morphology) or hormonal disorder were excluded.Body mass index (BMI) was significantly higher in the OD group, as were waist circumference and insulin and leptin serum levels. Conversely, serum follicle stimulating hormone (FSH) levels were significantly lower. After adjustment for BMI, only serum FSH level remained significantly different between the 2 groups. Discriminant analysis suggested that FSH may have a much stronger effect on OD than BMI.Low serum FSH level may contribute to OD in some obese women, independently of BMI. The pathophysiological mechanism of this finding and its impact on therapeutic strategies must be clarified.

Serum AMH (anti-Mullerian hormone) is the latest marker for the assessment of the ovarian reserve in women. It is synthetized by small antral follicles, which are precisely the ones counted on ultrasound for the antral follicle count (AFC). Serum AMH can therefore be used as a surrogate to the AFC in the evaluation of the ovarian reserve.

Study question Is the negative correlation between the numbers of 2-5 and 6-9 mm follicles influenced by ovarian and/or metabolic parameter(s) in young control women and in patients with polycystic ovarian syndrome (PCOS)? Summary answer Our study confirmed that the negative correlation between numbers of follicles sized 2-5 and 6-9 mm was stronger in PCOS than in young control women and was not linked to any ovarian or metabolic parameter. What is known already Previous reports described a direct negative correlation between the number of small antral follicles (2-5 mm) and large antral follicle (6-9 mm) during the early follicular phase (cycle Days 2-5) in normal and PCOS women. Numerous factors, that could be either intrinsic to the ovary or secondary to metabolic influence and/or gonadotropin regulation, might account for this. Study design, size, duration Six hundred and thirty-nine patients with PCOS according to Rotterdam Criteria and 157 control women were recruited in this retrospective cross-sectional study from January 2009 to January 2016. Participants/materials, setting, methods Data were obtained from a database of clinical, hormonal and ultrasound (U/S) features recorded consecutively in a single reproductive medicine centre. Univariate correlations between the various parameters were analysed by the Spearman's correlation test. All variables significantly related to the 2-5 and/or 6-9 mm follicle numbers were included in a principal component analysis (PCA) in order to structure the data and to obtain collections of uncorrelated variables, called principal components (PC), which are linear combinations of the original variables. Main results and the role of chance By univariate analysis, the 2-5 and 6-9 mm follicle numbers were strongly but negatively correlated in both populations. Many other variables were correlated to the 2-5 and/or 6-9 mm follicle numbers and to each other. By PCA, these relationships were gathered into four independent PCs in each population. In both groups, the 2-5 and 6-9 mm follicle numbers correlated strongly and inversely to a specific PC. Among the other variables tested, only serum oestradiol level correlated weakly to this PC in the control group. Two other uncorrelated PCs gathered relationships between variables linked to the metabolic status and the gonadotropin regulation both in control and PCOS women. Lastly, a fourth PC included relationships which linked to ovarian ageing in controls and to follicle dysregulation in patients with PCOS. Limitations, reasons for caution Our controls did not represent the general population since they were recruited in an ART centre; we used a modified Rotterdam classification for PCOS using follicle count and/or serum AMH level with in-house thresholds to define the follicle excess; the AMH assay used is no longer commercially available. Wider implications of the findings Factor(s) regulating specifically the equilibrium between the 2-5 and 6-9 mm follicle numbers still need(s) to be identified. More attention should be paid to the oocyte. Study funding/competing interest(s) None.

Polycystic ovarian syndrome (PCOS) is the most common cause of chronic anovulation and hyperandrogenism in young women and represents a true public health concern and an economic burden.The pathophysiology of PCOS is still not fully understood, but progresses have been made and the relationships between anti mullerian hormone (AMH), follicle stimulating hormone, luteinizing hormone, E2 and androgens have been explored. The follicle excess plays a central role in the syndrome and AMH is definitively a major component of this phenomena.The aim of this chapter is to present the recent work studying the role of AMH in the pathophysiology of PCOS and to discuss the improvement that serum AMH assay brings in the diagnosis of PCOS.

The pathophysiology of polycystic ovary syndrome (PCOS) is still not fully understood but the follicle excess plays a central role, and its mechanism in the folliculogenesis are multiple. According to the Rotterdam consensus held in 2003, the polycystic ovarian morphology (PCOM) is one of the three diagnostic criteria used to define PCOS. More specifically, PCOM is defined by an excessive antral follicle count with a follicle number per ovary (FNPO) ≥12 and/or ovarian volume ≥ 10 mL. With the improvement in ultrasonographic technology, the number of follicles seen on ultrasound has increased but it remains dependent on the specific equipment and operator. Serum anti-Mullerian hormone (AMH) is nowadays known to be a valuable tool to assess the ovarian follicle content, as AMH is synthetised by all growing follicles up to the stage of small antral follicles. Serum AMH might therefore be used as a surrogate for the FNPO in the diagnosis of PCOS, but so far technical issues have prevented from making it ‘the’ marker of follicle excess. If the assessment of follicle excess is important for the diagnosis of PCOS, it is also helpful for the management of those patients and in particular for reproductive issues.

International audience; In France until the end of 2015, oocyte donors must have had at least one child and be aged 18-37 years. This population of fertile women was selected to examine whether serum anti-Müllerian hormone (AMH) concentration could be a reliable correlate of spontaneous pregnancy in women who had proven their fertility before. A cohort of 217 women followed between 2009 and 2015 for oocyte donation at the University Hospital of Lille comprised this retrospective study. In these egg donors, aged 20-37 (median: 32 years), the median serum AMH level was 22 pmol/l (5-95th percentiles: 4.9-61.8). No significant correlation was found between serum AMH level and the number of children or the youngest child's age. Among the 32 women with AMH

En analysant différents gestes témoignant d’une virtuosité dans les écritures chorégraphiques contemporaines, cet article interroge le geste virtuose comme incorporation du pouvoir. Différentes expressions de cette virtuosité sont analysées, de la plus visible à la plus invisible, de la puissance du corps à son immobilité. Quoique relativement absente de la scène chorégraphique dans ses représentations, la question du pouvoir semble néanmoins être posée par de nombreux chorégraphes, qui, à leur manière, la donnent à voir et à ressentir. Ainsi, les gestes de chorégraphes tels qu’Olivier Dubois, Wim Vandekeybus, Rachid Ouramdane ou Hofesh Shechter sont décryptés afin de déterminer si la virtuosité agit comme soumission / résistance à une construction disciplinaire du corps (forgé par une technique, des normes sociales, politiques ou culturelles) ou s’il est possible de dépasser cette mise en jeu relativement binaire en voyant émerger une virtuosité plus invisible, plus complexe, qui viendrait sculpter différemment le corps dansant. Comment, alors, cheminer depuis la figuration du pouvoir en scène vers l’incorporation du pouvoir ? By considering various gestures of virtuosity in contemporary dance performances, this article studies the virtuoso gesture as an incorporative source of power. Different ways of expressing this virtuosity are analysed, from the most visible to the most invisible, from the power of the body to its immobility. Although relatively absent from the choreographic scene in its representations, the question of power seems nevertheless to be raised by many choreographers, who, in their own way, portray and convey it. And so the gestures of choreographers such as Olivier Dubois, Wim Vandekeybus, Rachid Ouramdane or Hofesh Shechter can be decoded so as to determine if virtuosity has the effect of submitting to or resisting a disciplinary construct of the body (created by technique, and social, political or cultural norms), or if it is possible to go beyond this relatively binary presentation by detecting the emergence of a less visible, more complex virtuosity which would show the dancing body differently. How, then, does one go from showing power on stage to the incorporation of power?

Cette etude porte sur douze interpretes issus de pratiques artistiques corporelles differentes (danse contemporaine, danse classique, acrobatie aerienne, acrobatie au sol et breakdance). Son but est d’identifier les comportements de danseurs-acrobates, qualifies de virtuoses ou qui se designent comme tels, a l’entrainement en observant leur processus de travail, dans le quotidien de la pratique d’une activite physique et artistique et dans le cadre d’un projet esthetique. Leur pratique quotidienne est soumise a un fort engagement athletique, alors que les etudes physiologiques menees sur les danseurs demontrent que leur condition physique est souvent en deca des exigences de leur discipline. Sur la base de methodes d’enquete ethnographique, d’observation participante, de pratique incorporee immersive et d’entretiens avec des danseurs, cette etude redefinit l’experience de la virtuosite au sein de la pratique d’entrainement du danseur. Pour les interpretes interroges, deux categories de virtuosite se dessinent : l’une « monodisciplinaire » qui s’evalue dans le rapport a la norme et a la technique (excellence classique, circassienne, sportive), l’autre « transdisciplinaire » posant la question d’un entrainement specifique par rapport a un projet artistique, lie a l’experience et au ressenti de l’interprete.

Background Pulsatile GnRH therapy is the gold standard treatment for ovulation induction in women having functional hypothalamic amenorrhea (FHA). The use of pulsatile GnRH therapy in FHA patients with polycystic ovarian morphology (PCOM), called “FHA-PCOM”, has been little studied in the literature and results remain contradictory. The aim of this study was to compare the outcomes of pulsatile GnRH therapy for ovulation induction between FHA and “FHA-PCOM” patients in order to search for an eventual impact of PCOM. Methods Retrospective study from August 2002 to June 2015, including 27 patients with FHA and 40 “FHA-PCOM” patients (85 and 104 initiated cycles, respectively) treated by pulsatile GnRH therapy for induction ovulation. Results The two groups were similar except for markers of PCOM (follicle number per ovary, serum Anti-Müllerian Hormone level and ovarian area), which were significantly higher in patients with “FHA-PCOM”. There was no significant difference between the groups concerning the ovarian response: with equivalent doses of GnRH, both groups had similar ovulation (80.8 vs 77.7 %, NS) and excessive response rates (12.5 vs 10.6 %, NS). There was no significant difference in on-going pregnancy rates (26.9 vs 20 % per initiated cycle, NS), as well as in miscarriage, multiple pregnancy or biochemical pregnancy rates. Conclusion Pulsatile GnRH seems to be a successful and safe method for ovulation induction in “FHA-PCOM” patients. If results were confirmed by prospective studies, GnRH therapy could therefore become a first-line treatment for this specific population, just as it is for women with FHA without PCOM.

Ovulation induction in patients having both functional hypothalamic amenorrhea (FHA) and polycystic ovarian morphology (PCOM) has been less studied in the literature. As results remain contradictory, no recommendations have yet been established.To compare pulsatile GnRH therapy versus gonadotropins for ovulation induction in "FHA-PCOM" patients and to determine if one treatment strikes as superior to the other.A 12-year retrospective study, comparing 55 "FHA-PCOM" patients, treated either with GnRH therapy (38 patients, 93 cycles) or with gonadotropins (17 patients, 53 cycles).Both groups were similar, defined by low serum LH and E2 levels, low BMI, excessive follicle number per ovary and/or high serum AMH level. Ovulation rates were significantly lower with gonadotropins (56.6% versus 78.6%, p = 0.005), with more cancellation and ovarian hyper-responses (14% versus 34% per initiated cycle, p 0.005). Pregnancy rates were significantly higher with GnRH therapy, whether per initiated cycle (26.9% versus 7.6%, p = 0.005) or per patient (65.8% versus 23.5%, p = 0.007).In our study, GnRH therapy was more successful and safer than gonadotropins, for ovulation induction in "FHA-PCOM" patients. If results were confirmed by prospective studies, it could become a first-line treatment for this population, just as it is for FHA women without PCOM.

International audience; Cryptorchidism is one of the most frequent causes of nonobstructive azoospermia (NOA) in adulthood. Although it is well known that spermatogenesis is more impaired in bilateral than in unilateral cryptorchidism, previous studies have only described small cohorts or inhomogeneous population. Consequently, we analyzed a cohort of 225 men with only a history of cryptorchidism as sole etiopathogenetic factor for NOA, and compared testicular sperm extraction (TESE) outcomes between men with bilateral versus unilateral cryptorchidism. Our results show no difference in follicle-stimulating hormone (FSH) levels and testicular volumes between men with a history of bilateral cryptorchidism compared to unilateral cryptorchidism (median: 21.3 IU l-1 vs 19.3 IU l-1, P = 0.306; and 7.2 ml vs 7.9 ml, P = 0.543, respectively). In addition, sperm retrieval rates were similar (66.2% vs 60.0%, P = 0.353). Using multivariate analysis, we have found that only a low inhibin B level (above the assay's detection limit) was positively associated with successful sperm retrieval (P < 0.05). Regarding intracytoplasmic sperm injection outcomes, we found that cumulative pregnancy rate and live birth rate per cycle were not statistically different between the two groups (17.4% vs 27.8%, P = 0.070; and 16.1% vs 26.4%, P = 0.067, respectively). Unexpectedly, there was no significant difference in hormonal profiles (FSH, luteinizing hormone [LH], testosterone, and inhibin B levels) and TESE outcomes between unilateral versus bilateral cryptorchidism. This suggests that a history of unilateral cryptorchidism could reflect a bilateral testicular impairment. Interestingly, inhibin B level might be a predictor of successful TESE.

International audience; Polycystic ovary syndrome (PCOS) is the most common cause of chronic anovulation and hyperandrogenism in young women. Excessive ovarian production of Anti-Müllerian Hormone, secreted by growing follicles in excess, is now considered as an important feature of PCOS. The aim of this review is first to update the current knowledge about the role of AMH in the pathophysiology of PCOS. Then, this review will discuss the improvement that serum AMH assay brings in the diagnosis of PCOS. Last, this review will explain the utility of serum AMH assay in the management of infertility in women with PCOS and its utility as a marker of treatment efficiency on PCOS symptoms. It must be emphasized however that the lack of an international standard for the serum AMH assay, mainly because of technical issues, makes it difficult to define consensual thresholds, and thus impairs the widespread use of this new ovarian marker. Hopefully, this should soon improve.

Cet article propose d’explorer les pratiques en mutation sur la scene choregraphique et interdisciplinaire contemporaine et s’interesse a l’incorporation d’un geste virtuose chez plusieurs interpretes a la croisee entre la danse et l’acrobatie. En s’interrogeant sur leurs habitudes de travail et sur leur perception du geste, ces interpretes revelent, qu’entre danse et cirque, se dessinent de nouvelles formes de virtuosites, reposant sur le desequilibre, le questionnement identitaire et une perte des reperes, qu’ils soient physiques, cognitifs, expressifs ou symboliques, envisages du point de vue de l’interprete.

Objective To determine cardiac and obstetric outcomes among women with Marfan syndrome (MS) whose pregnancies were managed in accordance with the French national guidelines. Methods A descriptive analysis was conducted for a prospective cohort of 18 women with MS who gave birth in the maternity unit of Bichat-Claude Bernard Hospital, Paris, France, between January 1, 1998, and May 31, 2011. The study hospital was the national referral center for MS and related diseases. Results A total of 22 pregnancies were recorded among the study cohort. Of these, 21 were managed according to the national guidelines. One woman who was referred to the study hospital during late pregnancy was not managed according to the national guidelines; this patient experienced aortic dissection at 37 weeks. In the cohort, aortic diameter did not increase significantly during pregnancy. Vascular fetal growth restriction was observed in 7 (31.8 %) of the pregnancies. Cesarean delivery was planned for 17 (77.3%) of the pregnancies. Conclusion Risk of aortic dissection was low among a cohort of pregnant women with MS who were managed according to the French national guidelines.

D’une multiplicite inherente a la pratique de la danse contemporaine, nous dessinerons les contours de l’interprete, les graphies d’un danseur, des deux dimensions du papier aux trois dimensions du corps et du plateau. De l’ecriture a l’interpretation, de la composition a la reception en passant par des notions de transmission ou de traduction et au sein de quelques realisations choregraphiques, nous analyserons des processus, par le biais de la description kinesthesique, relative a la sensation et la construction du mouvement danse.

National audience; Depuis le début des années 2000, le cirque s'est affirmé comme un objet d'étude à part entière, en particulier en sciences sociales et en esthétique. Les recherches se sont ainsi développées pour analyser les multiples transformations que ce monde l'art a connues suite à l'avènement du \guillemotleftnouveau cirque\guillemotright. En prenant pour objet d'analyse, au-delà des seuls artistes de cirque, d'autres catégories d'acteurs jusqu'ici moins étudiées, tels que les responsables culturels, les formateurs des écoles professionnelles ou encore les enseignants d'E.P.S., cet ouvrage invite à explorer la diversité des dynamiques professionnelles à l'øeuvre dans le secteur, en France ainsi qu'au niveau européen. Issues de deux journées d'études organisées par le Collectif de Chercheur·e·s sur le Cirque, les contributions de professionnel·le·s et de chercheur·e·s en sociologie, arts du spectacle, sciences de l'éducation, STAPS et littérature permettent de croiser les approches et les terrains pour aborder différents questionnements : les modalités des parcours des artistes de cirque, la question des identités professionnelles et de la reconnaissance de certains métiers ainsi que les enjeux liés aux multiples catégorisations des activités circassiennes.
