Abstract
The role of vaginal infections in recurrent miscarriage (RM) is discussed controversially and screening is not recommended in international guidelines. Peripheral and uterine NK cells (pNK, uNK) play an important role in the establishment of a healthy pregnancy and are targets of immune diagnostics in RM patients. The aim of this study was to analyze the composition of the vaginal microbiota in RM patients and to correlate the findings to clinical characteristics as well as NK cell parameters. In total, n=243 RM patients with ≥3 consecutive miscarriages were recruited between 11/2011 and 03/2016. Vaginal swabs were analyzed by microbiological culture. Further, a cervical swab was taken in n=187 patients and the presence of Chlamydia trachomatis was evaluated by a molecular assay. Peripheral blood levels of CD45+CD3-CD56+CD16+ pNK (determined by four-color fluorescence flow cytometry) and CD56+ uNK (uterine biopsy, determined by immunohistochemistry) were analyzed. The prevalence of Gardnerella vaginalis colonization in RM patients was 19.0%, gram-negative anaerobes 20.5%, Candida species 7.9%, group B Streptococcus 11.0% and Enterobacteriaceae 14.8%. Commensal lactobacilli were absent in 14.5% of the women. Chlamydia trachomatis was detected in n=1 case (0.53%). The prevalence of Gardnerella vaginalis and gram-negative anaerobes in RM patients with elevated pNK (>280/μl, n=69) was significantly higher (p=0.012, p=0.04) compared to patients with normal pNK (n=174). In conclusion, RM patients with elevated pNK suffer more often from colonization by Gardnerella vaginalis and gram-negative anaerobes. This might indicate an association between the vaginal microbiota, local inflammation, changes in immune parameters and miscarriage.

Abstract
Background Infertility patients often have high stress levels which, in some cases, represent a risk of developing depression or anxiety. The SCREENIVF questionnaire is a validated tool to evaluate such risks. Some coping strategies have been shown to be correlated with infertile couples' levels of stress. Determining which strategies are correlated with higher levels of risk for depression or anxiety could be useful to offer targeted psychological counseling to reduce the risk of depression or anxiety. Materials and Methods A total of 296 women and men who attended the Fertility Center at Heidelberg University Hospital completed the SCREENIVF questionnaire and the COMPI coping scales. Data were analyzed first on an individual basis and focused on the couple, using the Actor Partner Interdependence Model. Results On an individual level, active avoidance coping was positively correlated with a higher risk of depression or anxiety in women, while meaning-based coping was negatively correlated with risk in men. When the results of couples were viewed together, women and men using active avoidance coping exhibited higher risk scores as individuals (actor effect), as did their partners (partner effect). Women who used meaning-based coping had positive actor and partner effects. Women using active-confronting coping had a negative partner effect (higher risk score for men). Conclusions These findings indicate that some coping strategies may have a protective effect while others may increase the risk of emotional maladjustment in infertile couples. Further analysis of coping strategies could help to identify new counseling approaches for infertile patients.

Abstract
Extracellular vesicles (EVs) are released from almost all cells and tissues. They are able to transport substances (e.g. proteins, RNA or DNA) at higher concentrations than in their environment and may adhere in a receptor-controlled manner to specific cells or tissues in order to release their content into the respective target structure. Blood contains high concentrations of EVs mainly derived from platelets, and, at a smaller amount, from erythrocytes. The female and male reproductive tracts produce EVs which may be associated with fertility or infertility and are released into body fluids and mucosas of the urogenital organs. In this review, the currently relevant detection methods are presented and critically compared. During pregnancy, placenta-derived EVs are dynamically detectable in peripheral blood with changing profiles depending upon progress of pregnancy and different pregnancy-associated pathologies, such as preeclampsia. EVs offer novel non-invasive diagnostic tools which may reflect the situation of the placenta and the foetus. EVs in urine have the potential of reflecting urogenital diseases including cancers of the neighbouring organs. Several methods for detection, quantification and phenotyping of EVs have been established, which include electron microscopy, flow cytometry, ELISA-like methods, Western blotting and analyses based on Brownian motion. This review article summarises the current knowledge about EVs in blood and cord blood, in the different compartments of the male and female reproductive tracts, in trophoblast cells from normal and pre-eclamptic pregnancies, in placenta ex vivo perfusate, in the amniotic fluid, and in breast milk, as well as their potential effects on natural killer cells as possible targets.

Abstract
Peripheral and uterine NK cells (pNK, uNK) can be distinguished according to their receptor expression. Recent studies indicate an association of elevated pNK and uNK with recurrent miscarriage (RM). This study aimed to analyze pNK and uNK in patients with RM and healthy controls. Out of n=590 RM patients screened according to a standard diagnostic protocol, n=268 couples with ≥3 consecutive RM were identified. Subgroups consisted of n=151 primary RM (pRM), n=85 secondary RM (sRM), n=32 tertiary RM (tRM) and n=42 healthy controls. Finally, n=147 idiopathic RM (iRM) and n=121 non-iRM patients were identified. Peripheral blood levels of CD45+CD3-CD56+CD16+ NK cells were determined in non-pregnant patients and controls in the mid-luteal phase by FACS. In n=129 RM patients a uterine biopsy was taken to evaluate CD56+ NK cells by immunohistochemistry. PRM showed higher absolute pNK than sRM (median/μl (Q1;Q3): 234 (147;306) vs 176 (128;245), p=0.02). Further a trend towards higher pNK percentages in pRM was detected. UNK numbers did not differ between RM subgroups and did not correlate with pNK. However, the rate of highly elevated uNK was increased in iRM compared to non-iRM patients (p=0.04). Further, higher numbers of CD45+CD3-DR+ (p<0.01) and CD45+CD3+CD8+DR+ (p=0.04) peripheral lymphocytes were associated with higher uNK numbers. In conclusion, elevated pNK were present in pRM patients. Although pNK and uNK numbers did not correlate, the association between high CD45+CD3-DR+ and CD45+CD3+CD8+DR+ peripheral lymphocytes and uNK might indicate that activated NK, B and T cells provide cytokines for the differentiation of uNK.

Abstract
STUDY QUESTION What is the success rate in terms of ovarian activity (menstrual cycles) as well as pregnancy and delivery rates 1 year after orthotopic ovarian transplantations conducted in a three-country network? SUMMARY ANSWER In 49 women with a follow-up >1 year after transplantation, the ovaries were active in 67% of cases and the pregnancy and delivery rates were 33 and 25%, respectively. WHAT IS KNOWN ALREADY Cryopreservation of ovarian tissue in advance of cytotoxic therapies and later transplantation of the tissue is being performed increasingly often, and the total success rates in terms of pregnancy and delivery have been described in case series. However, published case series have not allowed either a more detailed analysis of patients with premature ovarian insufficiency (POI) or calculation of success rates based on the parameter 'tissue activity'. STUDY DESIGN, SIZE, DURATION Retrospective analysis of 95 orthotopic transplantations in 74 patients who had been treated for cancer, performed in the FertiPROTEKT network from 2008 to June 2015. Of those 95 transplantations, a first subgroup (Subgroup 1) was defined for further analysis, including 49 women with a follow-up period >1 year after transplantation. Of those 49 women, a second subgroup (Subgroup 5) was further analysed, including 40 women who were transplanted for the first time and who were diagnosed with POI before transplantation. PARTICIPANTS/MATERIALS, SETTING, METHODS Transplantation was performed in 16 centres and data were transferred to the FertiPROTEKT registry. The transplantations were carried out after oncological treatment had been completed and after a remission period of at least 2 years. Tissue was transplanted orthotopically, either into or onto the residual ovaries or into a pelvic peritoneal pocket. The success rates were defined as tissue activity (menstrual cycles) after 1 year (primary outcome) and as pregnancies and deliveries achieved. MAIN RESULTS AND THE ROLE OF CHANCE The average age of all transplanted 74 women was 31 ± 5.9 years at the time of cryopreservation and 35 ± 5.2 at the time of transplantation. Twenty-one pregnancies and 17 deliveries were recorded. In Subgroup 1, tissue was cryopreserved at the age of 30 ± 5.6 and transplanted at 34 ± 4.9 years. Ovaries remained active 1 year after transplantation in 67% of cases (n = 33/49), the pregnancy rate was 33% (n = 16/49) and the delivery rate was 25% (n = 12/49). In Subgroup 5, tissue was cryopreserved at the age 30 ± 5.9 years and transplanted at 34 ± 5.2 years. Ovaries remained active 1 year after transplantation in 63% of cases (n = 25/40), the pregnancy rate was 28% (n = 11/40) and the delivery rate was 23% (n = 9/40). The success rates were age dependant with higher success in women who cryopreserved at a younger age. In Subgroup 5, tissue was exclusively transplanted into the ovary in 10% (n = 4/40) of women and into a peritoneal pocket in 75% (n = 30/40), resulting in spontaneous conceptions in 91% of patients (n = 10/11). LIMITATIONS, REASONS FOR CAUTION The data were drawn from a retrospective analysis. The cryopreservation and transplantation techniques used have changed during the study period. The tissue was stored in many tissue banks and many surgeons were involved, leading to heterogeneity of the procedures. However, this does reflect the realistic situation in many countries. Although patients with POI were evaluated before transplantation to allow specific analysis of the transplanted tissue itself, the possibility cannot be excluded that residual ovarian tissue was also reactivated. WIDER IMPLICATIONS OF THE FINDINGS This is the largest case series worldwide to date and it confirms that cryopreservation and transplantation of ovarian tissue can be a successful option for preserving fertility. Persistent tissue activity 12 months after transplantation suggests that the pregnancy and delivery rates may increase further in the future. As transplantation into the peritoneum results in a high success rate, this approach may be an alternative to transplantation into the ovary. However, in order to establish the best transplantation site, a randomized study is required. STUDY FUNDING/COMPETING INTEREST This study was in part funded from the Deutsche Forschungsgemeinschaft (# DI 1525) and the Wilhelm Sander Foundation (2012.127.1) and did not receive any funding from a commercial company. No competing interests. TRIAL REGISTRATION NUMBER None.

Abstract
Abstract
Objective. A disturbance of sensorimotor gating measured by prepulse inhibition of acoustic startle (PPI) is one of the best tests of the schizophrenia-like behavior. Vasopressin was implicated in the development of schizophrenia; therefore, the naturally occurring vasopressin-deficient Brattleboro rat has been suggested to be a reliable non-pharmacological animal model. However, previous studies focusing on PPI deficit did not use proper control and despite clear gender differences in the development of the disorder, the effect of gender has been mostly neglected.
Methods. First, we compared the „noise” and „tone” type prepulse at 73-77-81 dB intensity during the light or dark phase using small (~150 g) or big (~500 g) Wistar rats. The test parameters were validated by a pharmacological schizophrenia model (30 mg/kg ketamine i.p.). Than male, female, and lactating vasopressin-deficient animals were compared with +/+ ones.
Results. We established that the prepulse “noise” type is not optimal for PPI testing. The cycle of the day as well as the body weight had no effect on PPI. Even if we compared vasopressin-deficient animals with their closely related +/+ controls, the PPI deficiency was visible with more pronounced effect at 77 dB prepulse intensity similarly to pharmacological schizophrenia model. Despite our expectation, the gender as well as lactation had no effect on the vasopressin-deficiency induced PPI deficit.
Conclusions. The present data confirmed and extended our previous studies that vasopressin-deficient rat is a good model of schizophrenia. It seems that female as well as lactating Brattleboro rats are useful tools for testing putative novel antipsychotics in line with special attention required for schizophrenic women.

Abstract
Purpose: Official guideline coordinated and published by the German Society of Gynecology and Obstetrics (DGGG). Aim of the guideline was to standardize the diagnosis and treatment of patients with recurrent miscarriage (RM). Recommendations were proposed, based on the current national and international literature and the experience of the involved physicians. Consistent definitions, objective assessments and standardized therapy were applied. Methods: Members of the different involved societies developed a consensus in an informal process based on the current literature. The consensus was subsequently approved by the heads of the scientific societies. Recommendations: Recommendations for the diagnosis and treatment of patients with RM were compiled which took the importance of established risk factors such as chromosomal, anatomical, endocrine, hemostatic, psychological, infectious and immunological disorders into consideration.

Abstract
The central role of the maternal immune system for successful and disturbed pregnancies such as recurrent miscarriage (RM) is apparent. Recent studies have increased understanding of the complex interaction of the different immunological players and the adaptation of the maternal immune system to the semi-allogeneic embryo. There is growing evidence for immunological abnormalities in RM patients, including autoimmune and allogeneic factors. However, the question remains unsolved whether these changes represent the cause or the consequence of RM. As in half of the RM patients the underlying mechanism remains unknown, further diagnostic methods are urgently needed. Within this review we summarize (recent) literature on the immunological diagnosis in RM patients to find out current trends and to identify potential targets of therapy. As the exact mechanisms of feto-maternal tolerance have not yet been determined we suggest that the immunological diagnosis should be implemented only in well-designed clinical trials in specialized centers to establish a standardized immunological work-up in RM patients.

Abstract
Introduction: As gender role attitudes and the evaluation of parenthood and childlessness have subtle variations in each society, cross-country studies focusing on infertility are needed to draw a complex picture in the psychosocial context of infertility. This study investigates similarities and differences between German and Hungarian infertile couples regarding infertility specific quality of life and personal gender role attitudes. Methods: A cross-sectional study was conducted with data of 540 participants (270 couples) attending the first fertility consultation in one fertility clinic in Germany and in five fertility clinics in Hungary. Data were collected between February 2012 and March 2013. Two psychological questionnaires were applied: The FertiQoL to measure infertility specific quality of life and the PAQ to measure gender role attitudes like "instrumental" acting (as a traditional "masculine" attitude) and "expressive" communicating (as a traditional "femine" attitude) and their combinations "combined" attitude (as both "instrumental" and "expressive") and "neutral" attitude (neither "instrumental" nor "expressive"). Results: German couples seeking assisted reproduction treatment are older aged and have longer lasting relationships than Hungarian couples. Hungarian couples scored higher on all quality of life scales than did German couples. In the Hungarian group, "combined" attitudes (use of both "expressive" and "instrumental" attitudes) is associated with higher levels of quality of life compared with other gender role attitudes. In the German group, individuals with "combined" attitudes seem to show better quality of life than those in "expressive" and "neutral" clusters. Conclusions: The strategy of using combined "expressive" and "instrumental" attitudes proved to act as a buffer against infertility-related stress for both members of the couple in two European countries and can therefore be recommended as helpful in counselling the infertile couple.

Abstract
Introduction: As gender role attitudes and the evaluation of parenthood and childlessness have subtle variations in each society, cross-country studies focusing on infertility are needed to draw a complex picture in the psychosocial context of infertility. This study investigates similarities and differences between German and Hungarian infertile couples regarding infertility specific quality of life and personal gender role attitudes. Methods: A cross-sectional study was conducted with data of 540 participants (270 couples) attending the first fertility consultation in one fertility clinic in Germany and in five fertility clinics in Hungary. Data were collected between February 2012 and March 2013. Two psychological questionnaires were applied: The FertiQoL to measure infertility specific quality of life and the PAQ to measure gender role attitudes like "instrumental" acting (as a traditional "masculine" attitude) and "expressive" communicating (as a traditional "femine" attitude) and their combinations "combined" attitude (as both "instrumental" and "expressive") and "neutral" attitude (neither "instrumental" nor "expressive"). Results: German couples seeking assisted reproduction treatment are older aged and have longer lasting relationships than Hungarian couples. Hungarian couples scored higher on all quality of life scales than did German couples. In the Hungarian group, "combined" attitudes (use of both "expressive" and "instrumental" attitudes) is associated with higher levels of quality of life compared with other gender role attitudes. In the German group, individuals with "combined" attitudes seem to show better quality of life than those in "expressive" and "neutral" clusters. Conclusions: The strategy of using combined "expressive" and "instrumental" attitudes proved to act as a buffer against infertility-related stress for both members of the couple in two European countries and can therefore be recommended as helpful in counselling the infertile couple.
