Abstract
STUDY QUESTION Is the psychosocial wellbeing affected in women and men shortly after allocation to a freeze-all strategy with postponement of embryo transfer compared to a fresh transfer strategy? SUMMARY ANSWER In general, psychosocial wellbeing (i.e. emotional reactions to the treatment, quality-of-life, infertility-related stress, and marital benefit) was similar in women and men allocated to a freeze-all versus those allocated to a fresh-transfer strategy 6 days after disclosure of treatment strategy (i.e. 4 days after oocyte retrieval), although women in the freeze-all group reported a slightly higher degree of depressive symptoms and mood swings compared to women in the fresh transfer group. WHAT IS KNOWN ALREADY The use of a freeze-all strategy, i.e. freezing of the entire embryo cohort followed by elective frozen embryo transfer in subsequent cycles has increased steadily over the past decade in assisted reproductive technology (ART). This strategy essentially eliminates the risk of ovarian hyperstimulation syndrome and has proven beneficial regarding some reproductive outcomes in subgroups of women. However, patients experience a longer time interval between oocyte retrieval and embryo transfer, hence a longer time to pregnancy, possibly adding additional stress to the ART treatment. So far, little focus has been on the possible psychosocial strains caused by postponement of embryo transfer. STUDY DESIGN, SIZE, DURATION This is a self-reported questionnaire based sub-study of a multicentre randomized controlled trial (RCT) including 460 women and 396 male partners initiating their first, second, or third treatment cycle of invitro fertilisation or intracytoplasmic sperm injection (ICSI) from May 2016 to September 2018. This sub-study was included in the primary project protocol and project plan for the RCT, as psychosocial wellbeing was considered a secondary outcome. PARTICIPANTS/MATERIALS, SETTING, METHODS Women from eight public fertility clinics in Denmark and Sweden and one private clinic in Spain were randomized in a 1:1 ratio on the day of inclusion (menstrual cycle day 2 or 3) to either a freeze-all strategy with postponement of embryo transfer to a subsequent modified natural menstrual cycle or a fresh transfer strategy with embryo transfer in the hormone stimulated cycle. Treatment allocation was blinded until the day of the ovulation trigger. Women and their male partners were asked to complete a validated self-reported questionnaire 6 days after unblinding of treatment group allocation, corresponding to 4 days after oocyte retrieval, investigating their psychosocial wellbeing related to the treatment defined as emotional reactions to the treatment, quality-of-life, infertility-related stress, and marital benefit. The questionnaire included items from the Copenhagen Multi-Centre Psychosocial Infertility (COMPI) Fertility Problem Stress Scales and the COMPI Marital Benefit Measure. MAIN RESULTS AND THE ROLE OF CHANCE Baseline characteristics were comparable between the two groups for both women and men. In total, response rates were 90.7% for women and 90.2% for men. In the freeze-all group, 207 women and 179 men completed the questionnaire compared with 204 women and 178 men in the fresh transfer group. Men in the two treatment groups did not differ in any of the explored aspects of psychosocial wellbeing (i.e. emotional reactions to the treatment, quality-of-life, infertility-related stress, and marital benefit) 6 days after disclosure of treatment strategy. Women in the freeze-all group reported a slightly higher degree of depressive symptoms (P = 0.045) and mood swings (P = 0.001) (i.e. variables included in 'emotional reactions to treatment') compared to women in the fresh transfer group. When adjusted for multiple testing, depressive symptoms were no longer significantly different between the two groups. No additional differences in psychosocial wellbeing were found. Self-reported quality-of-life during treatment was also rated as similar between the two groups in both women and men, but was slightly lower than they would rate their quality-of-life when not in fertility treatment. LIMITATIONS, REASONS FOR CAUTION Although response rates were high, selection bias cannot be excluded. As this study was an RCT, we assume that psychosocial characteristics of the participants were equally distributed in the two groups, thus it is unlikely that the identified psychosocial differences between the freeze-all and fresh transfer group were present already at baseline. Furthermore, the questionnaire was completed as a one-time assessment 4 days after oocyte retrieval, thus not reflecting the whole treatment process, whereas an assessment after the full completed treatment cycle is needed to draw firm conclusions about the psychosocial consequences of the whole waiting period. However, a question posted that late would be highly biased on whether or not a pregnancy had been achieved. WIDER IMPLICATIONS OF THE FINDINGS The results indicate that individuals in the freeze-all group exhibited slightly higher levels of depressive symptoms and mood swings compared to those in the fresh transfer group. Nevertheless, it is important to note that any worries related to potential emotional strains stemming from delaying embryo transfer should not overshadow the adoption of a freeze-all approach in cases where it is clinically recommended. As long as patients are provided with comprehensive information about the treatment strategy before initiating the process, it is worth emphasising that other aspects of psychosocial wellbeing were comparable between the two groups.

Abstract
Contrary to popular belief, we have known for many years that the endometrium is not a sterile environment and is considered to be a low-biomass milieu compared to the vagina. Numerous trials and studies have attempted to establish a valid sampling method and assess its physiological composition, but no consensus has been reached. Many factors, such as ethnicity, age and inflammation, can influence the microbiome. Moreover, it possesses a higher alpha-diversity and, therefore, contains more diverse bacteria than the vagina. For instance, Lactobacillus has been shown to be a predominant genus in the vaginal microbiome of healthy women. Consequently, even if a majority of scientists postulate that a predominance of Lactobacillus inside the uterus improves reproductive outcomes, vaginal contamination by these bacteria during sampling cannot be ruled out. Certain pathologies, such as chronic endometritis, have been identified as inflammation perpetrators that hinder the embryo implantation process. This pro-inflammatory climate created by dysbiosis of the endometrial microbiota could induce secondary inflammatory mediators via Toll-like receptors, creating an environment conducive to the development of endometriosis and even promoting carcinogenesis. However, studies to this day have focused on small populations. In addition, there is no clearly defined healthy uterine composition yet. At most, only a few taxa have been identified as pathogenic. As sampling and analysis methods become increasingly precise, we can expect the endometrial microbiota to be incorporated into future diagnostic tools and treatments for women's health.

Abstract
PURPOSE OF REVIEW Surgery is an integral element of treatment for infertility caused by endometriosis. This review summarizes the purported mechanisms of infertility in endometriosis, as well as the impacts of surgery for endometriosis on fertility, including pregnancy achieved spontaneously and with assisted reproductive technology (ART). RECENT FINDINGS Endometriosis' effect on fertility is multifactorial. The sequela of increased inflammation resulting from endometriosis causes alterations in ovarian, tubal, and uterine function. Removing or destroying these lesions reduces inflammation. Surgical treatment of both early-stage endometriosis and deeply infiltrating endometriosis improves spontaneous pregnancy rates and ART pregnancy rates. Conventional or robotic laparoscopy is the preferred surgical approach. SUMMARY Endometriosis has detrimental effects on fertility, including negative impacts on oocyte, tubal, and endometrial function. Laparoscopic surgery for endometriosis elevates both spontaneous and ART pregnancy rates above those achieved with expectant management alone. The resection or destruction of endometriosis implants reduces inflammation, which likely improves the multifactorial infertility related to endometriosis. This topic is complex and controversial; more research in the form of high-quality randomized control trials is needed.

Abstract
In order to inform patients undergoing ART regarding their chances for motherhood, it seems useful to describe "freeze all" outcomes according to the different potential indications. The goal of this study was to examine the impact of a "freeze-all approach" on the cumulative live birth rate (cLBR) according to the indication. It is a cohort study including women who had undergone ovarian stimulation (OS) using an antagonist protocol with GnRH agonist triggering between 09.2016 and 09.2018 followed by a freeze-all cycle of blastocyst embryos. The ART outcomes were compared between the two main indications of the freeze-all strategy which were in our cohort: risk of ovarian hyperstimulation syndrome (OHSS) and endometriosis. The ART outcomes were also described for the others indications (inadequate endometrium and/or premature progesterone elevation at trigger day, two or more previous ART failures, and autoimmune disease and/or a high risk of thromboembolic disease (AI and/or TE risk)). In total, 658 women were included. The cLBR in the total population was 37.7% (248/658). The cLBR was significantly higher in the "OHSS risk" group (133/281, 47.3%) than in the "endometriosis" group (69/190, 36.3%) (p = 0.017). No significant differences were noted regarding perinatal outcomes, except a significantly higher risk of placenta praevia (PP) observed in the "endometriosis" group (10.1%) (p = 0.002). The "freeze-all approach" yielded good results in terms of the cLBR and especially in case of OHSS risk. These data should be taken into account when informing patients about the ART strategy and their chances of motherhood.

Abstract
BACKGROUND Chronic Endometritis (CE) is a subtle pathology, likely infectious in most cases, with a negative impact on the female fertility, but often overlooked even among fertility specialists. The purpose of the study is to demonstrate the predominant infectious nature of CE and to find the best therapeutic option by comparing the results of oral antibiotic therapy versus intrauterine antibiotic infusion in patients with CE undergoing IVF procedures. The objective was to compare the cure rate of CE-defined as the percentage of patients without CE at the test of cure, between the two groups and, the hysteroscopic aspect with the positive CD 138 staining. METHODS This was a prospective, case-control study that took place in a single university fertility clinic, in Oradea, Romania and included 57 patients with CE divided into 2 groups: orally administered antibiotics group who received a combination of antibiotics compared to intrauterine infusion group who received intrauterine infusion of antibiotic. Chronic Endometritis was diagnosed through hysteroscopy and immunohistochemistry for CD 138. Patients in both groups were tested for CE twice to evaluate the cure rate after oral combination antibiotic therapy versus intrauterine infusion of antibiotic. RESULTS Out of 115 patients with endometrial biopsies 57 tested positive for CE, with a 49.6% chronic endometritis prevalence. Among the group that was administered oral antibiotics, 11 patients (45.83%) experienced CE resolution after triple antibiotic therapy. Of the intrauterine infusion group, 25 patients (89.29%) presented negative results (p 0.0020). The normal hysteroscopic aspect had a similar prevalence in the patients with immunohistochemical positive and negative CD 138. CONCLUSIONS Our study demonstrated the effectiveness and superiority of intrauterine antibiotic infusion over the use of oral combination antibiotic therapy for CE cure.

Abstract
The blastocyst expresses paternally derived alloantigens and induces inflammation during implantation. However, it is necessary for the onset of pregnancy. An abnormal response might result in a pathological course of pregnancy or pregnancy failure. On the other hand, a state of maternal immune tolerance is necessary to ensure the normal development of pregnancy by suppressing inflammatory processes. This article discusses recognized mechanisms and the significance of inflammatory processes for embryo implantation and pregnancy establishment. We would also like to present disorders involving excessive inflammatory response and their influence on events occurring during embryo implantation. The chain of correlation between the processes responsible for embryo implantation and the subsequent physiological course of pregnancy is complicated. Many of those interrelationships are still yet to be discovered. Undoubtedly, their recognition will give hope to infertile couples for the emergence of new treatments that will increase the chance of giving birth to a healthy child.

Abstract
PURPOSE The freeze-all strategy is widely used for ovarian hyperstimulation syndrome (OHSS) prevention. Indeed, it increases live birth rates among high responders and prevents preterm birth and small for gestational age. Why should not we extend it to all? METHODS A retrospective and monocentric study was conducted between January 2008 and January 2018 comparing the cumulative live birth rates (CLBR) between patients having undergone FAS and a control group using fresh embryo transfer (FET) and having at least one frozen embryo available. Analyses were made for the entire cohort (population 1) and for different subgroups according to confounding factors selected by a logistic regression (population 3), and to the BELRAP (Belgian Register for Assisted Procreation) criteria (population 2). RESULTS 2216 patients were divided into two groups: Freeze all (FA), 233 patients and control (C), 1983 patients. The CLBR was 50.2% vs 58.1% P = 0.021 for population 1 and 53.2% vs 63.3% P = 0.023 for population 2, including 124 cases and 1241 controls. The CLBR stayed in favour of the C group: 70.1% vs 55.9% P = 0.03 even when confounding variables were excluded (FA and C group, respectively, 109 and 770 patients). The median time to become pregnant was equally in favour of the C group with a median of 5 days against 61 days. CONCLUSION CLBR is significantly lower in the FA group compared to the C group with a longer time to become pregnant. Nevertheless, the CLBR in the FA group remains superior to that observed in previous studies.

Abstract
Relevance: To date, the success of in vitro fertilization (IVF) programs in Kazakhstan is 38%.
The purpose of the study was to evaluate the mechanisms of influence of various risk factors on endometrial receptivity in women in IVF programs.
Materials and Methods: This review was based on a search conducted for domestic and foreign publications available in Russian and international search systems (PubMed, eLibrary) for the past 25 years.
Results: Chronic endometritis is a verified cause of impaired receptivity. Many studies have proven the beneficial effect of complex empirical treatment using antibacterial, anti-inflammatory, hormonal therapy with transdermal forms of estrogens and vitamin therapy on the outcome of IVF.
Conclusion: The problem of recurrent implantation disorders in IVF programs is multifactorial. Women with unrealized reproductive function require rehabilitation after an unsuccessful fertilization attempt to prevent disorders of homeostasis and ensure adequate pain relief during transvaginal puncture of ovarian follicles. In addition to hormone therapy with transdermal forms of estradiol, complex rehabilitation measures shall include immunomodulatory therapy, psychotherapy, and vitamin therapy.

Abstract
OBJECTIVE Adenomyosis is a benign uterine disorder characterized by the invasion of the endometrium within the myometrium, starting from the junctional zone (JZ), the inner hormone dependent layer of the myometrium that plays an important role in sperm transport, implantation and placentation. The resulting histological abnormalities and functional defects may represent the pathogenic substrate for infertility and pregnancy complications. The objective of this paper is to review the literature to evaluate the correlation between inner myometrium alterations and infertility and to assess the role of JZ in the origin of adverse obstetric outcomes of both spontaneous and in vitro fertilization (IVF) pregnancies. METHODS we searched Pubmed for all original and review articles in the English language from January1962 until December 2019, using the MeSH terms of 'adenomyosis', 'junctional zone', combined with 'infertility', 'obstetrical outcomes', 'spontaneous conception', 'in vitro fertilization' and 'classification'. The review was divided into three sections to assess this pathogenic correlation, evaluating also the importance of classification of the disease. RESULTS AND CONCLUSIONS Absent or incomplete remodeling of the JZ can affect uterine peristalsis, alter vascular plasticity of the spiral arteries and activate inflammatory pathways, all related to adverse obstetric outcomes. Despite these observations, there is still limited evidence whether adenomyosis is a cause of infertility. However, it is reasonable to screen patients for adenomyosis, to consider pregnant women with diffuse adenomyosis at high risk of adverse obstetric outcomes, and to evaluate the importance of a noninvasive validated classification in the management of women with adenomyosis.

Abstract
OBJECTIVE To investigate the therapeutic effect of antibiotic treatment on pregnancy outcomes in the following frozen-thawed embryo transfer cycles of infertile women. DESIGN Retrospective study. SETTING University assisted reproduction unit. PATIENT(S) A total of 640 women were included. Among them, the number of CD138+ cells per high-power field (CD138+/HPF) in the endometrium at the first evaluation was 0 in 88 women; 315 women had 1-4 CD138+/HPF and the remaining 237 had ≥5 CD138+/HPF. Finally, 26 of 237 women had persistent chronic endometritis (PCE) diagnosed. INTERVENTION(S) Hysteroscopy and endometrial biopsy were performed in the proliferative phase. After antibiotic treatment, endometrial biopsy samples were collected again. MAIN OUTCOME MEASURE(S) Live birth rate. RESULT(S) No significant difference in pregnancy outcomes was found between women with CD138+/HPF = 0 and those with CD138+/HPF 1-4. The cure rate was 89.0% in women with CD138+/HPF ≥5 after treatment. The implantation rate (51.6% vs. 32.3%, relative risk [RR] 2.23, 95% confidence interval [CI] 1.07-4.66), clinical pregnancy rate (65.7% vs. 42.3%, RR 2.62, 95% CI 1.17-5.86), live birth rate (52.1% vs. 30.7%, RR 2.45, 95% CI 1.04-5.76), and cumulative live birth rate (64.2% vs. 38.5%, RR 2.88, 95% CI 1.27-6.51) were all significantly higher in women with CD138+/HPF ≤4 than in women with PCE. CONCLUSION(S) CD138+/HPF ≤4 in the endometrium had no negative impact on pregnancy outcomes. Antibiotic treatment was an effective way to improve the reproductive outcomes of women with CD138+/HPF ≥5. PCE was associated with poorer pregnancy outcomes.

Abstract
To evaluate the expression of genes encoding cytokines, grow factors and cell cycle regulators in the proliferative endometrium of women with chronic endometritis (CE) compared to controls. We performed a case-control study on seven women with CE as diagnosed by hysteroscopy and histology (Cases) compared to six women without CE (Controls). All women underwent diagnostic hysteroscopy plus endometrial biopsy during the mid-proliferative phase of the menstrual cycle. Endometrial samples were divided into two different aliquots for histological and molecular analyses. The endometrial expression profile of 16 genes encoding proteins involved in the inflammatory process, proliferation and cell cycle regulation/apoptosis was assessed by using high-throughput qPCR. Study endpoints were between-group differences in the expression of VEGF A, VEGF B, VEGF C, EGF, TNF, TGF B1, IFNG, TP73, TP73L, BAXva, CDC2, CDC2va, CCND3, CCNB1, BAX and IL12. RESULTS: VEGF A, VEGF B, VEGF C, EGF, TNF, TGF B1, IFNG, TP73, TP73L, BAXva, CDC2, CDC2va, CCND3, CCNB1 were significantly overexpressed in women with CE compared to controls, while BAX and IL12 had similar expression between groups. In women with CE, we found an altered endometrial expression of genes involved in inflammatory, cell proliferation, and apoptosis processes. The dominance of proliferative and anti-apoptotic activity in CE may potentially promote the development of polyps and hyperplastic lesions.

Abstract
Hydrosalpinx is a disease characterized by the obstruction of the salpinx, with progressive accumulation in the shape of a fluid-filled sac at the distal part of the tuba uterina, and closed to the ovary. Women with hydrosalpinges have lower implantation and pregnancy rates due to a combination of mechanical and chemical factors thought to disrupt the endometrial environment. Evidence suggests that the presence of hydrosalpinx reduces the rate of pregnancy with assisted reproductive technology. The main aim of the present is review to make an overview of the possible effects of hydrosalpinx on in vitro fertilization (IVF). We conducted a literature search on the PubMed, Ovid MEDLINE, and Google Scholar data bases regarding hydrosalpinx and IVF outcomes. Hydrosalpinx probably has a direct toxic effect on sperm motility and on the embryos. In addition, the increasing liquid inside the salpinges could alter the mechanisms of endometrial receptivity. The window of endometrial receptivity is essential in the implantation of blastocysts, and it triggers multiple reactions arising from the endometrium as well as the blastocysts. Hydrosalpinx could influence the expression of homeobox A10 (HOXA10) gene, which plays an essential role in directing embryonic development and implantation. Salpingectomy restores the endometrial expression of HOXA10; therefore, it may be one mechanism by which tubal removal could result in improved implantation rates in IVF. In addition, salpingectomy does not affect the ovarian response, nor reduces the antral follicle count. Further studies are needed to establish the therapeutic value of fluid aspiration under ultrasonographic guidance, during or after oocyte retrieval, in terms of pregnancy rate and ongoing pregnancy.

Abstract
ZusammenfassungDie Adenomyose ist durch endometriale Zellen im Myometrium charakterisiert. Zu den klinischen Beschwerden gehören Schmerzen, Blutungsstörungen und beeinträchtigte Fertilität. Die Abklärung beinhaltet eine gute Anamnese und die Bildgebung mit transvaginalem Ultraschall (TVUS) sowie ggf. Magnetresonanztomographie. Klassisch zeigt sich die Adenomyose im TVUS durch partielle Aufhebung der Junktionalzone. Die Therapie erfolgt ganzheitlich und beinhaltet ein gutes Schmerzmanagement. Bei jungen Patientinnen sollte eine endokrine Therapie erfolgen. Die Kinderwunschtherapie kann mit einer 3‑monatigen Down-Regulation mit Gonadotropin-Releasing-Hormon(GnRH)-Analoga eingeleitet werden. Bei notwendiger In-vitro-Fertilisation haben Protokolle mit ultralanger Down-Regulation oder zeitlich versetztem Embryotransfer nach GnRH-Analoga bessere Resultate gezeigt. Bei fortgeschrittener Erkrankung, abgeschlossener Familienplanung oder Therapieresistenz kommt die operative Sanierung oder Hysterektomie infrage.

The freeze-all strategy after IVF: which indications? Reprod Biomed Online 2020; 42:529-545.

Abstract
The freeze-all strategy is gaining popularity worldwide as an alternative to the conventional fresh embryo transfer. It consists of cryopreservation of the entire embryo cohort and the embryo transfer in a subsequent cycle that takes place separately from ovarian stimulation. The freeze-all strategy was initially a 'rescue' strategy for women at high risk of ovarian hyperstimulation syndrome; however, this approach has been extended to other indications as a scheduled strategy to improve implantation rates. This assumes that ovarian stimulation can alter endometrial receptivity in fresh cycles owing to the effect of supraphysiological levels of steroids on endometrial maturation. The procedure, however, has not been associated with increased live birth rates in all infertile couples, and concerns have been raised about the occurrence of several adverse perinatal outcomes. It is, therefore, crucial to identify in which subgroups of patients a freeze-all strategy could be beneficial. The aim of this review is to summarize current scientific research in this field to highlight potential indications for this strategy and to guide clinicians in their daily practice.

Abstract
OBJECTIVE To determine whether subfertility in patients with endometriosis is due to impaired endometrial receptivity by comparing pregnancy and live-birth outcomes in women with endometriosis versus two control groups without suspected endometrial factors: noninfertile patients who underwent assisted reproduction to test embryos for a single-gene disorder and couples with isolated male factor infertility. DESIGN Retrospective cohort. SETTING Multicenter private practice. PATIENT(S) All patients aged 24 to 44 years undergoing euploid frozen blastocysts transfer from January 2016 through March 2018. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Live birth, clinical pregnancies, pregnancy losses, and aneuploid rates in preimplantation genetic testing for aneuploidy cycles. RESULT(S) The analysis included 459 euploid frozen embryo transfer cycles among 328 unique patients. There were no differences in clinical pregnancy, pregnancy loss, or live-birth rates in patients with endometriosis compared with both control groups. The aneuploidy rates were lowest in the preimplantation genetic testing for monogenic disorders cohort, and the endometriosis patients had aneuploidy rates similar to those of the male factor infertility patients. CONCLUSION(S) It is unclear whether endometriosis primarily affects in vitro fertilization outcomes via oocyte quality or the endometrium. By controlling for embryo quality using euploid frozen embryo transfer cycles, we found no difference in pregnancy outcomes in patients with endometriosis compared with patients undergoing treatment for male factor infertility and noninfertile patients.

Abstract
An increasing number of researchers have alluded to the potential benefit of deferring the transfer of embryos produced during assisted reproductive technologies (ARTs) away from ovarian stimulation, using cryopreservation to enable this. The scientific evidence that may justify this recent trend in the use of the so-called 'freeze-all strategy' includes early, mostly small randomised controlled trials that have demonstrated an increase in live birth rates after elective embryo cryopreservation in certain patient populations, as well as evidence from cohort studies and retrospective analyses. What are the risks and benefits of freeze-all strategies in ART, who are the patients in whom it is likely to be advantageous, and does the current evidence allow us to identify situations when deciding that a fresh embryo transfer would be counter-productive? ART professionals are often faced with challenging clinical decisions regarding the best course of treatment for their patient. The purpose of this opinion paper is to provide a clinical guide for whether to perform a fresh embryo transfer or to opt for freezing all embryos in specific situations.

Abstract
New insights into the complex and fine-regulated inflammatory mechanisms involved in the endometrium reveal multiple facets to the problem of endometrial inflammation. However, the entity termed chronic endometritis is to date restricted to infectious etiology and managed with antibiotics. Conversely, the concept of impaired inflammatory state of the endometrium (IISE) provides a more global approach to defective endometrial inflammation, considering both infectious and non-infectious etiology. A non-systematic review was done through a search on MEDLINE, EMBASE, Global Health, The Cochrane Library, Health Technology Assessment Database and Web of Science, research registers. Pertinent original and review articles, published in English or French until December 31, 2019, were selected. A compelling body of evidence demonstrates transient, repeated and persistent IISE to be a major factor of most problematic disorders in obstetrics/gynecology, such as endometrial polyps, unexplained infertility, miscarriage, placenta-related pathology and endometrial cancer. When scheduled accordingly, hysteroscopy can play a key role in the IISE assessment. Robust data suggests the pertinence of minimal-effective anti-inflammatory regimens for therapeutic IISE targeting. This review provides a comprehensive update on the multiple facets of inflammation in the endometrial physiology and pathology. Further research is needed to improve classification, diagnosis and treatment of IISE.

Abstract
Endometriosis, or endometrioid disease, is a chronic estrogen-dependent gynecological disease caused by ectopic localization of endometrial tissue, mainly in the pelvis and ovaries. However, at the present stage of development of reproductive medicine, the classical topographic definition of endometriosis should be expanded with new significant characteristics established using the achievements of cell and molecular biology, which allowed a more detailed study of the pathogenesis of this disease. In addition, the introduction of personalized approaches to the treatment of patients with endometriosis and infertility, more attention should be paid to the search for disease predictors and the formation of risk groups with the observation of patients from puberty to menopause. In this review, we have analyzed the literature data and our own studies with an emphasis on factors and markers of decreased receptivity of eutopic endometrium in women with endometriosis, as well as pain, the manifestations of which can contribute to the exact diagnosis of external genital endometriosis.

Abstract
BACKGROUND The reproductive impact of adenomyosis and endometriosis is widely researched but the extent of these impacts remains elusive. It has been demonstrated that endometriosis, in particular, is known to result in subfertility but endometriosis and adenomyosis are increasingly linked to late pregnancy complications such as those caused by placental insufficiency. At the molecular level, the presence of ectopic endometrium perturbs the endometrial hormonal, cellular, and immunological milieu, negatively influencing decidualization, placentation, and developmental programming of the embryo. It is unclear if and how such early aberrant reproductive development relates to pregnancy outcomes in endometriosis and adenomyosis. OBJECTIVE AND RATIONALE The aims of this systematic review and meta-analysis were to (i) investigate the association of adenomyosis and endometriosis with fertility, obstetric, and neonatal outcomes of women through both assisted reproduction and natural conception and (ii) determine whether endometriosis disease subtypes have specific impacts on different stages of the reproductive process. SEARCH METHODS A systematic literature review of NHS evidence electronic databases and the Cochrane database identified all comparative and observational studies between 1980 and December 2018 in any language on adenomyosis and endometriosis with fertility, obstetric, and neonatal outcomes (23 search terms used). A total of 104 papers were selected for data extraction and meta-analysis, with use of Downs and Black standardized checklist to evaluate quality and bias. OUTCOMES We found that endometriosis consistently leads to reduced oocyte yield and a reduced fertilization rate (FR), in line with current evidence. Milder forms of endometriosis were most likely to affect the fertilization (FR OR 0.77, CI 0.63-0.93) and earlier implantation processes (implantation rate OR 0.76, CI 0.62-0.93). The more severe disease by American Society for Reproductive Medicine staging (ASRM III and IV) influenced all stages of reproduction. Ovarian endometriosis negatively affects the oocyte yield (MD -1.22, CI -1.96, -0.49) and number of mature oocytes (MD -2.24, CI -3.4, -1.09). We found an increased risk of miscarriage in both adenomyosis and endometriosis (OR 3.40, CI 1.41-8.65 and OR 1.30, CI 1.25-1.35, respectively), and endometriosis can be associated with a range of obstetric and fetal complications including preterm delivery (OR 1.38, CI 1.01-1.89), caesarean section delivery (OR 1.98 CI 1.64-2.38), and neonatal unit admission following delivery (OR 1.29, CI 1.07-1.55). WIDER IMPLICATIONS Adenomyosis and the subtypes of endometriosis may have specific complication profiles though further evidence is needed to be able to draw conclusions. Several known pregnancy complications are likely to be associated with these conditions. The complications are possibly caused by dysfunctional uterine changes leading to implantation and placentation issues and therefore could potentially have far-reaching consequences as suggested by Barker's hypothesis. Our findings would suggest that women with these conditions should ideally receive pre-natal counselling and should be considered higher risk in pregnancy and at delivery, until evidence to the contrary is available. In order to expand our knowledge of these conditions and better advise on future management of these patients in reproductive and maternal medicine, a more unified approach to studying fertility and reproductive outcomes with longer term follow-up of the offspring and attention to the subtype of disease is necessary.

[PMID: 32197993 DOI: 10.1016/j.jmig.2020.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Revised: 03/08/2020] [Accepted: 03/11/2020] [Indexed: 11/18/2022]
Abstract
STUDY OBJECTIVE To compare the tolerability and diagnostic accuracy of virtual ultrasonographic hysteroscopy (VUH) with that of conventional diagnostic outpatient hysteroscopy in the workup of patients who are infertile. DESIGN A single-center, retrospective cohort study. SETTING Department of Obstetrics and Gynecology, Gynecologic Oncology, and Minimally Invasive Pelvic Surgery Unit of Sacred Heart Hospital Don Calabria in Negrar, Italy. PATIENTS A total of 120 consecutive women who underwent hysterosalpingosonography and subsequent VUH and conventional hysteroscopy for infertility evaluation were included. The inclusion criterion was infertility for at least 1 year, with evaluation in the early or intermediate follicular phase of the menstrual cycle. INTERVENTIONS After the placement of an intracervical catheter, a Ringer Lactate solution was injected into the uterine cavity and fallopian tubes, and a 3D volume was obtained. The ultrasound volume acquired was successively elaborated offline, and a VUH was performed. Subsequently, a variable amount of air was introduced into the uterine cavity, and the patency of the salpinges was evaluated. MEASUREMENTS AND MAIN RESULTS The VUH findings were compared with those of conventional hysteroscopy performed in the subsequent month. For the detection of endometrial pathology in the overall pool, the sensitivity and specificity of VUH in comparison with conventional hysteroscopy were 100% (95% confidence interval [CI], 84.6%-100%) and 100% (95% CI, 96.3%-100%), respectively. For the detection of uterine cavity pathology and uterine malformations in the overall pool, the sensitivities of VUH were 80% (95% CI, 28.4%-99.5%) and 100% (95% CI, 75.3%-100%), respectively, with specificities of 100% (95% CI, 96.8%-100%) and 100% (95% CI, 96.6%-100%), respectively, when compared with conventional hysteroscopy. The positive predictive values for endometrial pathology, uterine cavity alterations, and uterine malformations were 100% (95% CI, 84.6%-100%), 100% (95% CI, 39.8%-100%), and 100% (95% CI, 75.3%-100%), respectively, with a receiver operating characteristic area of 100%, 90% (95% CI, 70%-100%), and 100%, respectively. There were no cases of severe vasovagal reactions or other complications. Most patients (67%, 81 of 120 women) described the examination as "less painful than expected," 25% (30 of 120 women) "just as expected," and only 7% (9 of 120 women) as "more painful than expected." CONCLUSION VUH was well tolerated and showed a high accuracy (100%) in the study of the uterine cavity when compared with conventional hysteroscopy.

Abstract
Endometriosis is associated with changes in long non-coding RNA (lncRNA) and mRNA expression, but the exact changes during the implantation window are unknown. Therefore, this study aimed to explore the lncRNA and mRNA expression profiles in the uterus of rats with endometriosis during the implantation window. A total of 35 non-pregnant female rats were randomized to the endometriosis (n=13), adipose tissue control (n=8) and blank control (n=14) groups. On the 5th day of pregnancy, the rats were sacrificed to obtain uterine tissues. lncRNA and mRNA were analyzed using gene chips. A total of five differentially expressed lncRNA and four mRNA were validated by reverse transcription-quantitative (RT-q)PCR. Immunohistochemistry and western blotting were used to determine the expression of the ADAM metal-lopeptidase with thrombospondin type 1 motif 7 (Adamts7), tumor protein p53 (Tp53), distal-less homeobox 3 (Dlx3) and pyrimidinergic receptor P2Y6 (P2ry6) proteins. There were 115 upregulated lncRNAs, 51 downregulated lncRNAs, 97 upregulated mRNAs and 85 downregulated mRNAs in the endometriosis group. RT-qPCR confirmed the trends for five lncRNAs and four mRNAs (Adamts7, Tp53, Dlx3 and P2ry6). The relative protein expression levels of Adamts7, P2ry6, Dlx3 and TP53 were significantly different in the endometriosis group (P<0.05 vs. controls). Bioinformatics predicted the co-expression relationship of the selected five lncRNA and four mRNA. Gene ontology and the Kyoto Encyclopedia of Genes and Genomes predicted that Adamts7, P2ry6, Dlx3 and TP53 were involved in endometriosis-related inflammation and reproductive pathways. In conclusion, the changes in the expression of lncRNAs, mRNAs and proteins (Adamts7, P2ry6, Dlx3 and TP53) may possibly affect endometrial receptivity in rats with endometriosis during the implantation window, probably resulting in implantation failure of the embryo.

Abstract
Pelvic endometriosis is a complex syndrome characterized by an estrogen-dependent chronic inflammatory process that affects primarily pelvic tissues, including the ovaries. It is caused when shed endometrial tissue travels retrograde into the lower abdominal cavity. Endometriosis is the most common cause of chronic pelvic pain in women and is associated with infertility. The underlying pathologic mechanisms in the intracavitary endometrium and extrauterine endometriotic tissue involve defectively programmed endometrial mesenchymal progenitor/stem cells. Although endometriotic stromal cells, which compose the bulk of endometriotic lesions, do not carry somatic mutations, they demonstrate specific epigenetic abnormalities that alter expression of key transcription factors. For example, GATA-binding factor-6 overexpression transforms an endometrial stromal cell to an endometriotic phenotype, and steroidogenic factor-1 overexpression causes excessive production of estrogen, which drives inflammation via pathologically high levels of estrogen receptor-β. Progesterone receptor deficiency causes progesterone resistance. Populations of endometrial and endometriotic epithelial cells also harbor multiple cancer driver mutations, such as KRAS, which may be associated with the establishment of pelvic endometriosis or ovarian cancer. It is not known how interactions between epigenomically defective stromal cells and the mutated genes in epithelial cells contribute to the pathogenesis of endometriosis. Endometriosis-associated pelvic pain is managed by suppression of ovulatory menses and estrogen production, cyclooxygenase inhibitors, and surgical removal of pelvic lesions, and in vitro fertilization is frequently used to overcome infertility. Although novel targeted treatments are becoming available, as endometriosis pathophysiology is better understood, preventive approaches such as long-term ovulation suppression may play a critical role in the future.

Abstract
BACKGROUND Further knowledge about the pubertal development mode of girls with Turner syndrome (TS) who have undergone hormone replacement therapy (HRT) is beneficial to the proposal of an optimal HRT regimen. This study examined the pubertal development mode of girls with TS who underwent HRT and evaluated the characteristics of optimal sex induction therapy in girls with TS. METHOD We conducted a retrospective, longitudinal study over the past two decades at The First Affiliated Hospital, Sun Yat-sen University. PATIENTS Seventy-one patients with TS and two groups of normal Chinese girls. RESULTS The total investigation time was 3.00 (2.00, 4.66) years. The interval of each stage was significantly longer (P < 0.001) in the girls with TS than that in the normal Chinese girls, except for B2-3 (P = 0.011). The uterine volumes of the girls with TS in stages B2 and 3 were greater than those of the control group (P = 0.046), whereas the uterine volume of the control group was inversely greater than that of the TS group among those who reached stages B4 and 5 (P = 0.034). During HRT, the uterine volume grew significantly from all previous stages except for breast stage 5 (B3 vs.2: Z = - 2.031; P = 0.042; B4 vs. 3: Z = - 2.273; P = 0.023; B5 vs. 4: Z = - 1.368; P = 0.171). The paired data of 27 girls with TS showed that the uterine volume (17.93 ± 9.31 ml vs. 13.75 ± 6.67 ml) and width (2.54 ± 0.66 cm vs. 2.22 ± 0.36 cm) increased significantly during artificial cycles compared with before artificial cycles (t = - 2.79 and - 2.51, P = 0.01 and 0.018). CONCLUSION HRT led to normal breast development in girls with TS; half of the girls with TS in our study reached Tanner stage B5, although the uterus ultimately developed suboptimally. The girls' breasts and uteruses grew quickly at the beginning of HRT (stages B2-4). An optimal HRT regimen for girls with TS may specifically focus on Tanner stages B2-4 and artificial cycles.

Abstract
PURPOSE OF REVIEW To review recent findings related to possible causes of recurrent implantation failure of endometrial origin in normal uterus. RECENT FINDINGS Recent evidences suggest that in apparently normal endometria, RIF may associate with molecular and functional changes in the uterus such as abnormal endometrial microbiota, including the presence of chronic endometritis, poor synchronization between the blastocyst and endometrium, and/or excessive uterine peristalsis. An altered endometrial microbiota detected by molecular techniques has been recently related to poorer embryo implantation, even in apparently normal endometria. The use of the endometrial receptivity analysis test to obtain an objective signature of endometrial receptivity has shown to improve the reproductive performance in RIF patients. The diagnosis of uterine peristalsis, however, remains challenging since the usual evaluation by transvaginal ultrasound is not accurate, and drugs tested to reduce uterine peristalsis and enhance embryo implantation have not been clearly beneficial. Finally, endometrial injury to improve implantation rates remains controversial being definitive well-designed trials needed to assess its benefit, if any. SUMMARY In recurrent implantation failure of endometrial origin an altered pattern of the microbial endometrial ecosystem, a displaced window of implantation leading to desynchronization between the blastocyst and the endometrium, or an altered pattern of uterine contractions during embryo transfer may be factors to consider in our attempt to solve this clinical issue. New diagnostics for assessing these conditions and new therapies to improve these dysfunctional situations are currently under investigation to be presumably included in the near future in the work-up of affected patients.

Abstract
OBJECTIVE To characterize endometrial structural and functional state and receptivity in women with hysteromyoma (HM) and chronic endometritis (CE) in infertile couples. MATERIAL AND METHODS A total of 130 patients who had HM and/or CE in an infertile couple were examined. Group 1 included 64 women with HM and CE; Group 2 consisted of 24 patients with HM; group 3 comprised 42 patients with EC. A control group included endometrial biopsy specimens from 20 healthy women planning a pregnancy. RESULTS Patients with HM and CE were found to develop endometrial dysfunction. Its structural signs were damage to the endometrial surface epithelium; intense stromal fibrosis with the high expression of type III and IV collagens; dysregulated processes of high angiogenesis; impaired maturation of pinopodia by the implantation window; high estrogen receptor (ER) expression in the nuclei of endometrial glandular and stromal cells; low progesterone receptor (PR) expression; and impaired secretory endometrial transformation. CONCLUSION HM concurrent with CE is responsible for endometrial dysfunction. Its structural manifestations are mainly associated with CE.

Abstract
OBJECTIVE To investigate the effectiveness of Tornado and Hilal (Cook Medical, Bloomington, IN) hysteroscopic proximal tubal occlusion (HPTO) for hydrosalpinx (HX) treatment before in vitro fertilization (IVF) and embryo transfer (ET) in patients with dense pelvic adhesions or low ovarian reserve. DESIGN A retrospective study of patients treated between May 2014 and May 2016 (Canadian Task Force classification III). SETTING A university-affiliated center. PATIENTS One hundred fifty women with unilateral or bilateral HX who were not candidates for laparoscopic surgery. INTERVENTION Tornado or Hilal HPTO before IVF-ET and/or frozen ET. MEASUREMENTS AND MAIN RESULTS The main outcome was the cumulative live birth rate. Tornado or Hilal placement was successful for 143 (95.3%) patients. Of the 132 patients who underwent 204 ET cycles, 86 (65.2%) conceived, and 78 (59.1%) resulted in live births. The overall early and late miscarriage rates per clinical pregnancy were 12.8% and 1.1%, respectively. The ectopic pregnancy rate was 2.3%. No major complications occurred. CONCLUSION Tornado or Hilal HPTO is an effective alternative for treating HX before IVF-ET/frozen ET in patients with dense pelvic adhesions or low ovarian reserve.

Abstract
PROBLEM The correlations between chronic endometritis and unexplained infertility are unexplored. METHOD OF STUDY We performed a retrospective study on consecutive patients referred to our hysteroscopy service due to unexplained infertility. All women underwent endometrial sampling with histological and cultural examinations. If chronic endometritis was diagnosed, patients received antibiotic therapy, and chronic endometritis resolution was subsequently ascertained by histological examination. We aimed to estimate chronic endometritis prevalence and the effects of antibiotic therapy on spontaneous conception during the year following hysteroscopy. RESULTS A total number of 95 women were included. Pooled prevalence of chronic endometritis was 56.8%. Antibiotic therapy resulted in chronic endometritis resolution in 82.3% of patients, while in 17.6% disease was persistent. Women with cured chronic endometritis showed higher pregnancy rate and live birth rate in comparison with both women with persistent disease and women without chronic endometritis diagnosis (pregnancy rate = 76.3% vs 20% vs 9.5%, P < .0001; live birth rate = 65.8% vs 6.6% vs 4.8%, P < .0001). CONCLUSION Chronic endometritis is highly prevalent in patients with unexplained infertility. Diagnosis and treatment of chronic endometritis improve spontaneous pregnancy rate and live birth rate in such patients.

Deferred Frozen Embryo Transfer: What Benefits can be Expected from this Strategy in Patients with and without Endometriosis? JOURNAL OF ENDOMETRIOSIS AND PELVIC PAIN DISORDERS 2017.

Abstract
Progress with cryopreservation techniques have enabled development of the deferred frozen-thawed embryo transfer (DET) strategy as an alternative to relying on fresh embryo transfers. With DET, the entire embryo cohort is cryopreserved, and embryo transfer is then performed in a subsequent cycle that takes place separately from the controlled ovarian stimulation (COS). Initially developed to limit the risk of ovarian hyperstimulation syndrome that occurs with high responders, this strategy has been applied extensively with other populations in an effort to improve implantation rates. The assumption is that COS, which is essential for in vitro fertilization/intra cytoplasmic sperm injection (IVF/ICSI) procedures to obtain a multi-follicular development, could have a detrimental impact on the endometrium as a result of greatly elevated levels of steroids. It is currently not clear whether the DET strategy can be generally applied to all women requiring an IVF/ICSI procedure. The objectives of this literature review regarding DET, were hence: (i) to present the scientific background that contributed to extensive adoption of this technique, (ii) to detail the pregnancy outcomes and potential obstetric and neonatal consequences, (iii) to report on its ability to prevent risks induced by COS, and (iv) to propose indications for the DET strategy in clinical practice.

Abstract
Development of adhesions commonly occurs in association with surgery for endometriosis. Even in the absence of surgery, women with endometriosis appear to be at an enhanced risk of developing adhesions. In the current study, we utilized a chimeric mouse model of experimental endometriosis in order to examine the role of inflammasome activation in the development of postsurgical adhesions. Mice were randomized to receive peritoneal injections of human endometrial tissue fragments or endometrial tissue conditioned media (CM) from women with or without endometriosis 16 hours after ovariectomy and placement of an estradiol-releasing silastic capsule. A subset of mice receiving CM was also treated with interleukin (IL) 1 receptor antagonist (IL-1ra). Our studies demonstrate that peritoneal injection of endometrial tissue fragments near the time of surgery resulted in extensive adhesive disease regardless of tissue origin. However, adhesion scores were significantly higher in mice receiving CM from tissues acquired from patients with endometriosis compared to control tissue CM ( P = .0001). Cytokine bead array analysis of endometrial CM revealed enhanced expression of IL-1β from patients with endometriosis compared to controls ( P < .01). Finally, the ability of human tissue CM to promote adhesive disease was dramatically reduced in mice cotreated with IL-1ra ( P < .0001). Our data implicate enhanced expression of IL-1β in women with endometriosis as a potential causal factor in their increased susceptibility of developing postsurgical adhesions. Thus, targeting inflammasome activation may be an effective strategy for the prevention of surgical adhesions in patients with endometriosis.

Abstract
BACKGROUND A detailed assessment of the uterus forms a pivotal part of the ART treatment process. The emergence of three-dimensional ultrasound (3D US) has provided clinicians with a highly powerful tool in this respect. Assessments with 3D US range from the reconstruction of anatomical planes elusive to conventional US, to the objective measurement of anatomical volumes and vascularization parameters. However, despite the ever increasing number of publications emerging in the literature, the question of which aspects of 3D US are of most clinical value remains a topic of debate. OBJECTIVE AND RATIONALE The objective of this review is to dissect which aspects of the 3D US assessment of the uterus are supported by a strong level of evidence to date, and should therefore be incorporated into current routine clinical practice. SEARCH METHODS We conducted a systematic search of the PubMed database up to May 2016, using a combination of text words and Medical Subject Headings (MeSH) pertaining to the 3D US assessment of the uterus. All articles published in the English language were screened to ascertain relevance to women of reproductive age; further citations were retrieved through manual reference list searching. OUTCOMES A multitude of predominantly observational studies were identified, which concerned a vast variety of 3D US uterine assessments. All articles unequivocally praised the non-invasive, cost-effective, highly acceptable and objective nature of 3D US. Studies regarding the value of assessing the endometrial volume and vascularization prior to embryo transfer appeared conflicting and inconsistent. Studies regarding the imaging of uterine pathology and identification of intratubal and intrauterine devices consistently reported high rates of diagnostic accuracy. A recent RCT did not show an improvement in clinical outcomes when comparing 3D versus 2D US during embryo transfer. However, preliminary studies suggested that 3D US is superior in determining the site of implantation, particularly in ambiguous cases such as interstitial and angular pregnancies. Finally, pilot studies have suggested that the further integration of 3D and possibly 4D US with surgical interventions of the uterus may be a promising prospect. WIDER IMPLICATIONS 3D US may prove to be an invaluable tool in the assessment of the uterus within the context of ART. Currently, the aim should be to highlight the aspects of 3D US that are most evidence-based and valuable for patients, and to incorporate these into routine clinical practice.

Abstract
OBJECTIVE This study aims at evaluating the endometrial receptivity in uterus of pregnant rats exposed to nicotine via examination of integrin expression by immunohistochemical effect. METHODS In this study, 16 healthy pregnant rats were divided into two groups of control and study groups each comprising eight rats. The rats randomised to study group were given a certain amount of nicotine before and during the pregnancy. Integrin expression was detected in uterus of all rats by immunohistochemical staining. The effect of nicotine exposure on embryo implantation and the endometrial receptivity were immunohistochemically and pathologically evaluated. RESULTS Comparison of both groups revealed no difference in living, viable foetuses. Intensity and universality of immunohistochemical staining of Integrin β3 for endometrial epithelium and endometrial stroma were detected to be identical between the groups. CONCLUSION No immunochemical effect was observed on integrin expression, which is a very important part of receptivity in an animal model created with pregnant rats that were transdermally exposed to nicotine. Our study demonstrated that the harmful effect of nicotine use before and pregnancy on implantation is limited at the level of integrin expression, in a dose-dependent manner and also by considering the method of administration.

Abstract
In the literature, there is growing evidence that assisted reproductive techniques increase the risk of pregnancy complications in subfertile couples. Moreover, many concomitant preconception risk factors for subfertility are frequently present in the same subject and increase the risk of pregnancy complications. This review aimed to summarize in a systematic fashion the best current evidence regarding the effects of preconception maternal factors on maternal and neonatal outcomes. A literature search up to March 2016 was performed in IBSS, SocINDEX, Institute for Scientific Information, PubMed, Web of Science and Google Scholar. An evidence-based hierarchy was used to determine which articles to include and analyse. Available data show that the risk of pregnancy complications in spontaneous and assisted conceptions is likely multifactorial, and the magnitude of this risk is probably very different according specific subgroups of patients. Notwithstanding the only moderate level and quality of the available evidence, available data suggest that the presence and the treatment of specific preconception cofactors of subfertility should be always taken into account both in clinical practice and for scientific purposes.
