Abstract
Hydrogen sulfide (H2S), previously regarded as a toxic exhaust and atmospheric pollutant, has emerged as the third gaseous signaling molecule following nitric oxide (NO) and carbon monoxide (CO). Recent research has revealed significant biological effects of H2S in a variety of systems, such as the nervous, cardiovascular, and digestive systems. Additionally, H2S has been found to impact reproductive system function and may have therapeutic implications for reproductive disorders. This paper explores the relationship between H2S and male reproductive disorders, specifically erectile dysfunction, prostate cancer, male infertility, and testicular damage. Additionally, it examines the impact of H2S regulation on the pathophysiology of the female reproductive system, including improvements in preterm birth, endometriosis, pre-eclampsia, fetal growth restriction, unexplained recurrent spontaneous abortion, placental oxidative damage, embryo implantation, recovery of myometrium post-delivery, and ovulation. The study delves into the regulatory functions of H2S within the reproductive systems of both genders, including its impact on the NO/cGMP pathway, the activation of K+ channels, and the relaxation mechanism of the spongy smooth muscle through the ROCK pathway, aiming to broaden the scope of potential therapeutic strategies for treating reproductive system disorders in clinical settings.

Abstract
Background Euploid blastocyst implantation failure may result from embryonic factors undetectable by preimplantation genetic testing for aneuploidy (PGT-A); however, various nonembryonic factors can also intricately interfere with implantation. This review seeks to clarify evidence-based testing and treatments for implantation failure after euploid embryo transfer. Methods We conducted a review of the literature on implantation failure after euploid embryo transfer or multiple embryo transfer cycles, which mainly included systematic reviews and meta-analyses. Results The recommended tests for implantation failure include (1) hysteroscopy, (2) endometrial CD138 immunohistochemistry and bacterial culture, (3) serum 25-hydroxyvitamin D3, and (4) thrombophilia screening. Based on diagnostic findings, the following treatments have been recommended: (1) antibiotics for chronic endometritis, (2) vitamin D replacement, (3) lifestyle modification, and (4) low-dose aspirin starting from the postimplantation period for thrombophilia. Moreover, frozen-thawed single euploid blastocyst transfer using assisted hatching and hyaluronan-enriched transfer medium may support embryo implantation. Conclusion To ensure a successful pregnancy in subsequent embryo transfers, simple, inexpensive, and evidence-based tests and treatments should be selected.

Abstract
To assess whether post-hysterosalpingography evaluation was associated with pregnancy rate and to identify independent risk factors for pregnancy success after salpingostomy in patients with hydrosalpinx. A retrospective analysis was conducted on the clinical data of 47 patients diagnosed with hydrosalpingography (HSG) in our hospital from 2015 to 2018. These patients received laparoscopic surgery and another salpingography within 2 months after surgery. According to the fallopian tube conditions evaluated by HSG before and after surgery, the patients could be divided into two groups. According to the pregnancy rate and postoperative HSG of patients with hydrosalpinx after laparoscopy, the total pregnancy rate of the tubal improved group was 65.62%, while that of the non-improved group was 20%, with statistical significance (p < 0.05). We found that hysterosalpingography after salpingostomy in patients with hydrosalpinx can provide reference for clinical treatment and improve the prognosis of patients.

Abstract
AIMS To explore suggestions for clinicians on the most effective treatment for hydrosalpinx undergoing IVF-ET. MATERIALS AND METHODS We reviewed 936 women with hydrosalpinx and 6715 tubal infertile women without hydrosalpinx who underwent IVF/ICSI between January 2014 and August 2019 in our center. Hydrosalpinx patients received different treatments including laparoscopic surgery (only salpingectomy and proximal tubal occlusion/ligation were included), ultrasonic-guided aspiration and hysteroscopic tubal occlusion. Outcomes were analyzed by One-way ANOVA, Chi-Square test and logistic regression. RESULTS The live birth rate (LBR) of laparoscopic surgery was significantly higher compared with hydrosalpinx aspiration (48.3% vs 39.6%, p = .024). The cumulative live birth rate (CLBR) of subsequent laparoscopic surgery was significantly higher compared with subsequent hysteroscopic occlusion (65.1% vs 34.1%, p = .001) and no subsequent treatment (65.1% vs 44.9%, p < .005). Subsequent laparoscopic surgery significantly improved the CLBR of hydrosalpinx patients who received ultrasonic-guided aspiration and didn't get clinical pregnancy in fresh cycles (Odds Ratio (OR) =1.875; 95%CI = 1.041-3.378, p = .036). CONCLUSIONS Laparoscopic surgery leads to significantly higher LBR than ultrasonic-guided aspiration and significantly higher CLBR than hysteroscopic occlusion and no treatment.

Abstract
Hydrosalpinx is a chronic inflammatory condition with high recurrence rate, and it is reported among female population having fallopian tubal factor infertility. Previously, we have reported that interventional ultrasound sclerotherapy improves endometrial receptivity and pregnancy rate with negligible adverse effects in patients suffering from hydrosalpinx. During present investigation, we have used next generation sequencing (NGS) to characterize the isomiR profiles from the endometrium of patients suffering from hydrosalpinx before and after interventional ultrasound sclerotherapy. Our results indicated that miRNA arm shift and switch remained unaffected when compared in patients before and after interventional ultrasound sclerotherapy. We observed that isomiRs with trimming at 3’ and isomiRs with canonical sequences were lower in post-treatment than in pre-treatment group. Gene ontology (GO) annotation and KEGG pathway analysis revealed that the expression of mature mir-30 was significantly lower in the pre-treatment as compared to post treatment group while the expression of mir-30 isomiR was 4.26-fold higher in pre-treatment when compared with the post-treatment group. These different expression patterns of mir-30 mature miRNA and mir-30 isomiRs in two groups are affecting the physiological function of the endometrium. Our results suggested that differential isomiR distribution in hydrosalpinx patients before and after treatment plays an important role in hydrosalpinx incidence and can help in designing novel strategy for the treatment of hydrosalpinx in female population.

Abstract
Progesterone has been shown to be a potent suppressor of several inflammatory pathways. During pregnancy, progesterone levels increase, allowing for normal pregnancy establishment and maintenance. The dysregulation of progesterone, as well as inflammation, leads to poor pregnancy outcomes. However, it is unclear how progesterone imbalance could impact inflammatory responses in the oviduct and subsequently result in early pregnancy loss. Therefore, in this review, we describe the role of progesterone signaling in regulating the inflammatory response, with a focus on the oviduct and pathological conditions in the Fallopian tubes.

Abstract
OBJECTIVE To evaluate the role of hydrosalpinx in susceptibility to chronic endometritis (CE). METHODS This is a retrospective cohort study, which includes 624 patients with hydrosalpinx (group A) and 789 patients without hydrosalpinx (group B) undergoing laparoscopy and hysteroscopy simultaneously. Endometrial morphology was recorded under hysteroscopy. Endometrial biopsy was obtained after hysteroscopy, and immunohistochemical staining for syndecan-1 (CD138) was carried out. RESULTS No significantly statistical differences were found between the two groups when comparing the incidence of endometrial hyperemia or endometrial micro-polyps under hysteroscopy (P > 0.05). Hydrosalpinx had a significant impact on the incidence of CE (P < 0.05) (plasma cell count: no plasma cells: odds ratio [OR] 0.71, 95% confidence interval [CI] 0.58-0.88, P = 0.002; ≥1/high-power field [HPF]: OR 1.40, 95% CI 1.14-1.74, P = 0.002; ≥3/HPF: OR 1.50, 95% CI 1.18-1.91, P = 0.001; ≥5/HPF: OR 1.62, 95% CI 1.27-2.21, P < 0.001). There were no significant differences in the comparison of plasma cell count between the unilateral hydrosalpinx group (274 patients) and the bilateral hydrosalpinx group (350 patients) (P > 0.05). CONCLUSION The presence of hydrosalpinx increased the incidence of CE. Bilateral hydrosalpinx did not significantly increase the incidence of CE compared with unilateral hydrosalpinx.

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
STUDY QUESTION Are there phase-specific changes in the early secretory (ES) phase human tubal lavage proteome that can inform and potentially optimize IVF culture media? SUMMARY ANSWER The human tubal lavage proteome during the ES phase relative to the menstrual phase reveals substantial differential protein abundance in pathways such as glycolysis, redox homeostasis and activation of 14-3-3 zeta-mediated signaling. WHAT IS KNOWN ALREADY The Fallopian tube is uniquely suited to the development of the preimplantation embryo as it transits the tube during the ES phase of the menstrual cycle. Euploid cleavage-stage embryo arrest may reflect incomplete recapitulation of in-vivo conditions by current media formulations. STUDY DESIGN, SIZE, DURATION Proteome-wide analysis of distal tubal lavage specimens collected from 26 healthy women undergoing open microtubal anastomosis surgery from January 2013 to January 2018 was performed. Specimens were grouped by menstrual cycle phase in order to analyze phase-specific differences in protein abundance. For the murine embryo assay, single-cell embryos (N = 482) were collected from superovulated wild type C57BL/6 female mice and cultured in microdrops over 5 days for the assessment of blastocyst development. PARTICIPANTS/MATERIALS, SETTING, METHODS Human tubal lavage specimens were processed for label-free mass spectrometry. Reported menstrual cycle day was confirmed by measuring serum hormones. Key protein targets in the ES phase were validated via immunoblot. The ES phase-specific increase in 14-3-3 zeta protein was confirmed via ELISA of conditioned media obtained from primary human Fallopian tube epithelial cell culture. A murine embryo assay was performed to investigate the impact of graduated concentrations of 14-3-3 zeta on the blastocyst development rate. MAIN RESULTS AND THE ROLE OF CHANCE Comparison of the ES and menstrual phase human tubal lavage proteomes revealed 74 differentially expressed proteins with enrichment of pathways and biological processes involved in the regulation of carbohydrate metabolism, oxidative stress and cell survival. The adapter-regulator protein 14-3-3 zeta was among the most significantly increased in the ES phase. Supplementation of embryo culture media with 14-3-3 zeta at concentrations tested did not significantly improve the murine blastocyst development. LIMITATIONS, REASONS FOR CAUTION Although select associations were recapitulated in the conditioned media from sex steroid exposed primary human tubal epithelial cells, cell culture represents an in-vitro approximation. Changes to embryo culture media, such as protein supplementation, must undergo rigorous preclinical safety testing prior to adoption for human use. WIDER IMPLICATIONS OF THE FINDINGS This study represents the first description of the human Fallopian tube lavage proteome across the menstrual cycle, revealing a unique proteomic signature during the ES phase. Although supplementation of culture media with 14-3-3 zeta at appropriate concentrations showed no significant impact on the murine blastocyst development rate, other biologically plausible candidate proteins for individual or high throughput testing strategies are identified. STUDY FUNDING/COMPETING INTEREST(S) This work was funded in part by an Army Medical Department Advanced Medical Technology Initiative grant from the United States Army Medical Research and Materiel Command's Telemedicine and Advanced Technology Research Center. There are no competing interests. TRIAL REGISTRATION NUMBER N/A.

Abstract
BACKGROUND Tubal disease accounts for 20% of infertility cases. Hydrosalpinx, caused by distal tubal occlusion leading to fluid accumulation in the tube(s), is a particularly severe form of tubal disease negatively affecting the outcomes of assisted reproductive technology (ART). It is thought that tubal surgery may improve the outcome of ART in women with hydrosalpinges. OBJECTIVES To assess the effectiveness and safety of tubal surgery in women with hydrosalpinges prior to undergoing conventional in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). SEARCH METHODS We searched the Cochrane Gynaecology and Fertility (CGF) Group trials register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, DARE, and two trial registers on 8 January 2020, together with reference checking and contact with study authors and experts in the field to identify additional trials. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing surgical treatment versus no surgical treatment, or comparing surgical interventions head-to-head, in women with tubal disease prior to undergoing IVF. DATA COLLECTION AND ANALYSIS We used Cochrane's standard methodological procedures. The primary outcomes were live birth rate (LBR) and surgical complication rate per woman randomised. Secondary outcomes included clinical, multiple and ectopic pregnancy rates, miscarriage rates and mean numbers of oocytes retrieved and of embryos obtained. MAIN RESULTS We included 11 parallel-design RCTs, involving a total of 1386 participants. The included trials compared different types of tubal surgery (salpingectomy, tubal occlusion or transvaginal aspiration of hydrosalpingeal fluid) to no tubal surgery, or individual interventions to one another. We assessed no studies as being at low risk of bias across all domains, with the main limitations being lack of blinding, wide confidence intervals and low event and sample sizes. We used GRADE methodology to rate the quality of the evidence. Apart from one moderate-quality result in one review comparison, the evidence provided by these 11 trials ranged between very low- to low-quality. Salpingectomy versus no tubal surgery No included study reported on LBR for this comparison. We are uncertain of the effect of salpingectomy on surgical complications such as the rate of conversion to laparotomy (Peto odds ratio (OR) 5.80, 95% confidence interval (CI) 0.11 to 303.69; one RCT; n = 204; very low-quality evidence) and pelvic infection (Peto OR 5.80, 95% CI 0.11 to 303.69; one RCT; n = 204; very low-quality evidence). Salpingectomy probably increases clinical pregnancy rate (CPR) versus no surgery (risk ratio (RR) 2.02, 95% CI 1.44 to 2.82; four RCTs; n = 455; I2 = 42.5%; moderate-quality evidence). This suggests that in women with a CPR of approximately 19% without tubal surgery, the rate with salpingectomy lies between 27% and 52%. Proximal tubal occlusion versus no surgery No study reported on LBR and surgical complication rate for this comparison. Tubal occlusion may increase CPR compared to no tubal surgery (RR 3.21, 95% CI 1.72 to 5.99; two RCTs; n = 209; I2 = 0%; low-quality evidence). This suggests that with a CPR of approximately 12% without tubal surgery, the rate with tubal occlusion lies between 21% and 74%. Transvaginal aspiration of hydrosalpingeal fluid versus no surgery No study reported on LBR for this comparison, and there was insufficient evidence to identify a difference in surgical complication rate between groups (Peto OR not estimable; one RCT; n = 176). We are uncertain whether transvaginal aspiration of hydrosalpingeal fluid increases CPR compared to no tubal surgery (RR 1.67, 95% CI 1.10 to 2.55; three RCTs; n = 311; I2 = 0%; very low-quality evidence). Laparoscopic proximal tubal occlusion versus laparoscopic salpingectomy We are uncertain of the effect of laparoscopic proximal tubal occlusion versus laparoscopic salpingectomy on LBR (RR 1.21, 95% CI 0.76 to 1.95; one RCT; n = 165; very low-quality evidence) and CPR (RR 0.81, 95% CI 0.62 to 1.07; three RCTs; n = 347; I2 = 77%; very low-quality evidence). No study reported on surgical complication rate for this comparison. Transvaginal aspiration of hydrosalpingeal fluid versus laparoscopic salpingectomy No study reported on LBR for this comparison, and there was insufficient evidence to identify a difference in surgical complication rate between groups (Peto OR not estimable; one RCT; n = 160). We are uncertain of the effect of transvaginal aspiration of hydrosalpingeal fluid versus laparoscopic salpingectomy on CPR (RR 0.69, 95% CI 0.44 to 1.07; one RCT; n = 160; very low-quality evidence). AUTHORS' CONCLUSIONS We found moderate-quality evidence that salpingectomy prior to ART probably increases the CPR compared to no surgery in women with hydrosalpinges. When comparing tubal occlusion to no intervention, we found that tubal occlusion may increase CPR, although the evidence was of low quality. We found insufficient evidence of any effect on procedure- or pregnancy-related adverse events when comparing tubal surgery to no intervention. Importantly, none of the studies reported on long term fertility outcomes. Further high-quality trials are required to definitely determine the impact of tubal surgery on IVF and pregnancy outcomes of women with hydrosalpinges, particularly for LBR and surgical complications; and to investigate the relative efficacy and safety of the different surgical modalities in the treatment of hydrosalpinges prior to ART.

Abstract
Background The aim of this study was to determine whether the treatment with doxycycline before and after oocyte retrieval is as effective as salpingectomy in minimizing the detrimental effect of hydrosalpinx on the outcomes of IVF-ET. Methods A retrospective analysis was done for the outcomes of the IVF-ET cycles of patients with hydrosalpinx who underwent laparoscopic salpingectomy prior to IVF cycle (n = 260) or were treated with extended doxycycline treatment during the IVF cycle (n = 45). In doxycycline group, doxycycline (100 mg twice daily) was started 1 week before anticipated oocyte retrieval and was continued for 1 week after oocyte retrieval. In salpingectomy group, the mesosalpinx was coagulated as close as possible to the fallopian tube. Results The implantation, clinical pregnancy, ongoing pregnancy and live birth rates were significantly higher in the salpingectomy group (20.87% Vs. 9.91%, P value =0.007, 44.62% Vs. 20%, P value = 0.002, 39.62% Vs. 17.78%, P value = 0.005 and 37.31% Vs. 15.56%, P value = 0.005 respectively). Conclusion Salpingectomy is more effective than extended doxycycline treatment in improving the outcomes of IVF-ET in patients with hydrosalpinx undergoing IVF-ET. Further, larger well designed randomized controlled trials should be conducted to confirm the findings of this study.

Abstract
PURPOSE We developed and applied a universal strategy for preimplantation genetic testing for all cystic fibrosis gene mutations (PGT-CF) based on next-generation sequencing (NGS). METHODS A molecular protocol was designed to diagnose all CF mutations at preimplantation stage. The detection of CF mutations was performed by direct gene sequencing and linkage strategy testing 38 specific SNPs located upstream and inside the gene for PGT-CF. Seventeen couples at risk of CF transmission decided to undergo PGT-CF. Trophectoderm cell biopsies were performed on days 5-6 blastocysts. PGT for aneuploidy (PGT-A) was performed from the same samples. Tested embryos were transferred on further natural cycles. RESULTS PGT was performed on 109 embryos. Fifteen CF mutations were tested. PGT-CF and PGT-A were conclusive for, respectively, 92.7% and 95.3% of the samples. A mean of 24.1 SNPs was informative per couple. After single embryo transfer on natural cycle, 81.3% of the transferred tested embryos implanted. CONCLUSIONS The present protocol based on the entire CFTR gene sequencing together with informative SNPs outside and inside the gene can be applied to diagnose all CF mutations at preimplantation stage.

Abstract
Endometrial epithelium exhibits a robust ion transport activity required for dynamical regulation of uterine fluid environment and thus embryo implantation. However, there still lacks a thorough understanding of the ion transport processes and regulatory mechanism in peri-implantation endometrial epithelium. As a gaseous signaling molecule or gasotransmitter, hydrogen sulfide (H2S) regulates a myriad of cellular and physiological processes in various tissues, including the modulation of ion transport proteins in epithelium. This study aimed to investigate the effects of H2S on ion transport across mouse endometrial epithelium and its possible role in embryo implantation. The existence of endogenous H2S in pregnant mouse uterus was tested by the detection of two key H2S-generating enzymes and measurement of H2S production rate in tissue homogenates. Transepithelial ion transport processes were electrophysiologically assessed in Ussing chambers on early pregnant mouse endometrial epithelial layers, demonstrating that H2S suppressed the anion secretion by blocking cystic fibrosis transmembrane conductance regulator (CFTR). H2S increased intracellular Cl- concentration ([Cl-]i) in mouse endometrial epithelial cells, which was abolished by pretreatment with the CFTR selective inhibitor CFTRinh-172. The cAMP level in mouse endometrial epithelial cells was not affected by H2S, indicating that H2S blocked CFTR in a cAMP-independent way. In vivo study showed that interference with H2S synthesis impaired embryo implantation. In conclusion, our study demonstrated that H2S inhibits the transepithelial anion secretion of early pregnant mouse endometrial epithelium via blockade of CFTR, contributing to the preparation for embryo implantation.

Abstract
Purpose/Aim of the Study: The present study investigated the effect of surgical adhesives on the uterus of rabbits and the histomorphology alterations following occlusion, to improve the clinical treatment of abnormal fallopian tube with surgical adhesives for in vitro fertilization and embryo transfer (IVF-ET). Materials and Methods: The experimental rabbits received laparotomy and occlusion of the uterus by surgical adhesive adjacent to the two fallopian tubes, while the control rabbits only received laparotomy. The body weight, hysterosalpingography, and histomorphology were measured to evaluate the uterine occlusion at 1 and 6 months after surgery. Results: There was no significant difference in the mortality rate or body weight between the experimental and control groups. In the experimental group, 38 uterine cavities were identified in 19 rabbits, of which 97.37% were occluded, with expanded uterine cavity and tissue oppression at 1 month after surgery. In total, 33 uterine cavities out of the 36 in the control group were occluded, with proliferation of new stratified epithelial cells observed at 6 months after surgery. In the control group, 20 uterine cavities of 10 rabbits were observed to be absent of occlusion at 1 month after surgery, while 18 uterine cavities in the remaining 9 rabbits were also absent of occlusion at 6 months after the surgery. Conclusion: Surgical adhesives are effective in occluding the uterus of rabbits without adverse effects, supporting their potential clinical use to treat the occlusion in abnormal fallopian tubes prior to IVF-ET.

Abstract
OBJECTIVE We conducted the research in order to explore the impact of hydrosalpinx fluid (HSF) on endometrium. METHOD HSF group: 261 patients with HSF scheduled to undergo laparoscopic surgery 3 to 7 days after menstruation in our center. Hysteroscopy would also be performed in order to observe the endometrial morphology during the surgery. Sixty (60) patients would be randomly selected for endometrial biopsy in order to detect the inflammatory cytokines TNF-a and IL-2 mRNA. Non-HSF group: 210 patients with no evidence of HSF due to chronic salpingitis or pelvic adhesion. IVF-ET treatment was performed after eliminating the factor of male infertility and hysteroscopy was conducted before the treatment. Fifty (50) patients underwent endometrial biopsy in order to detect TNF-a and IL-2 mRNA. RESULTS Hysteroscopy was performed in 261 patients with HSF and 210 patients without HSF. The incidence rate of endometritis manifestation among these two groups of patients was 37.2% (97/261) and 20.5% (43/210), respectively. The incidence rate of endometritis in the patients with HSF is significantly higher than in the patients without HSF (p<0.05). Sixty (60) patients from the HSF group and 50 patients from the non-HSF group were regrouped according to inflammatory and normal manifestation after the endometrial biopsy. There were 49 patients in the inflammatory manifestation group and 61 patients in the normal manifestation group. RT-PCR technology was adopted to detect the expression of inflammatory cytokines TNF-a and IL-2 mRNA in endometrial tissue. The level of TNF-a mRNA expression in endometrial tissues with inflammatory manifestation was higher than in normal endometrium (76.75±11.95 vs. 23.45±9.75, p<0.01). There are significant differences between them. The level of IL-2 mRNA expression in endometrial tissues with inflammatory manifestation was higher than that found in normal endometrium (80.56±13.35 vs. 35.12±8.35, p<0.01). There are significant differences between them. CONCLUSION Chronic endometritis is related to HSF and may therefore affect endometrial receptivity.

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.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2016; 48:434-445. [PMID: 26922863 DOI: 10.1002/uog.15900] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2015] [Revised: 02/11/2016] [Accepted: 02/22/2016] [Indexed: 06/05/2023]
Abstract
OBJECTIVE The presence of hydrosalpinx impairs the outcome of in-vitro fertilization embryo transfer (IVF-ET). Surgical methods to either aspirate the fluid or isolate the affected Fallopian tubes have been attempted as a means of improving outcome. The aim of this network meta-analysis was to compare the effectiveness of surgical treatments for hydrosalpinx before IVF-ET. METHODS An electronic search of MEDLINE, Scopus, Cochrane Central Register of Controlled Trials (Central) and the US Registry of clinical trials for articles published from inception to July 2015 was performed. Eligibility criteria included randomized controlled trials of women with hydrosalpinx before IVF-ET comparing ultrasound-guided aspiration of the fluid, tubal occlusion, salpingectomy or no intervention. Ongoing pregnancy was the primary outcome and clinical pregnancy, ectopic pregnancy and miscarriage were secondary outcomes. A random-effects network meta-analysis synthesizing direct and indirect evidence from the included trials was carried out. We estimated the relative effect sizes as risk ratios (RRs) and obtained the relative ranking of the interventions using cumulative ranking curves. The quality of evidence according to GRADE guidelines, adapted for network meta-analysis, was assessed. RESULTS Proximal tubal occlusion (RR, 3.22 (95% CI, 1.27-8.14)) and salpingectomy (RR, 2.24 (95% CI, 1.27-3.95)) for treatment of hydrosalpinx were superior to no intervention for ongoing pregnancy. For an outcome of clinical pregnancy, all three interventions appeared to be superior to no intervention. No superiority could be ascertained between the three surgical methods for any of the outcomes. In terms of relative ranking, tubal occlusion was the best surgical treatment followed by salpingectomy for ongoing and clinical pregnancy rates. No significant statistical inconsistency was detected; however, the point estimates for some inconsistency factors and their CIs were relatively large. The small study number and sizes were the main limitations. The quality of evidence was commonly low/very low, especially when aspiration was involved, indicating that the results were not conclusive and should be interpreted with caution. CONCLUSIONS Proximal tubal occlusion, salpingectomy and aspiration for treatment of hydrosalpinx scored consistently better than did no intervention for the outcome of IVF-ET. In terms of relative ranking, proximal tubal occlusion appeared to be the most effective intervention, followed by salpingectomy. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
AIM To investigate whether aspiration of hydrosalpinx during oocyte retrieval could improve the clinical outcome of in vitro fertilization-embryo transfer (IVF-ET). METHODS The clinical data of 598 IVF-ET cycles with tubal factor infertility at Reproductive Medical Center, 105 Hospital of People's Liberation Army, Anhui, China, between March 2011 and July 2015 were analyzed in this retrospective study. Among them, 71 cycles with unilateral or bilateral hydrosalpinx confirmed on both hysterosalpingography (HSG) and ultrasonography before controlled ovarian hyperstimulation (COH) were assigned to group A. A total of 51 cycles with unilateral or bilateral hydrosalpinx occurring during COH and confirmed on ultrasonography were assigned to group B. In both group A and group B, ultrasound-guided hydrosalpinx aspiration was performed in all patients when oocyte retrieval was finished. A further 35 cycles with unilateral or bilateral hydrosalpinx during COH received no intervention and were assigned to group C. A total of 441 cycles without hydrosalpinx on HSG or on ultrasonography before or during COH served as the control (group D). The IVF-ET outcomes of the four groups were analyzed and compared. RESULTS The embryo implantation rate and clinical pregnancy rate in group A and group C were significantly lower than those in group B and group D. The ongoing pregnancy rate in group A was significantly lower than that in group B and group D, and the ongoing pregnancy rate in group C was significantly lower than that in group D. CONCLUSION Aspiration of hydrosalpinx occurring during COH could significantly improve the clinical outcomes of IVF-ET, but not for the hydrosalpinx occurring before COH.

Abstract
The authors review aberrations of uterine anatomy and physiology affecting pregnancy outcomes with IVF. In the case of endometriosis and hydrosalpinx, pathologies outside of the uterus alter the uterine endometrium. In the case of endometriosis, Dominique de Ziegler outlines the numerous changes in gene expression and the central role of inflammation in causing progesterone resistance. With endometriosis, the absence of ovarian function inherent in deferred transfer, with or without a more lengthy suppression of ovarian function, appears to be sufficient to restore normal function of eutopic endometrium. Because laparoscopy is no longer routine in the evaluation of infertility, unrecognized endometriosis then becomes irrelevant in the context of assisted reproductive technology. With hydrosalpinx and submucus myomas, the implantation factor HOXA-10 is suppressed in the endometrium and, with myomas, even in areas of the uterus not directly affected. Daniela Galliano reviews various uterine pathologies, the most enigmatic being adenomyosis, where the endometrium also manifests many of the changes seen in endometriosis and deferred transfer with extended suppression appears to provide the best outcomes. Ettore Cicinelli's group has extensively studied the diagnosis and treatment of endometritis, and although more definitive diagnosis and care of this covert disorder may await techniques such as sequencing of the endometrial microbiome, it undoubtedly is an important factor in implantation failure, deserving our attention and treatment.

Mapping immunodominant antigens and H-2-linked antibody responses in mice urogenitally infected with Chlamydia muridarum. Microbes Infect 2012; 14:659-65.

Abstract
To identify immunodominant antigens and MHC-restricted antibody responses, seven different strains of mice were intravaginally infected with Chlamydia muridarum and compared for antibody responses to 257 C. muridarum proteins. The 7 strains of mice recognized a total of 109 proteins as antigens, of which, 5 antigens (TC0660, TC0727, TC0828, TC0726 & TC0268) were each recognized by 60% or more mice from each mouse strain and thus designated as immunodominant antigens. Furthermore, antibody responses to 19 other antigens displayed strong associations with mouse H-2 haplotypes, including 6 antigens (TC0480, TC0912, TC0229, TCA04, TC0289 & TC0892) whose antibody responses were linked to H-2(b), 8 (TC0035, TC0387, TC0052, TC0781, TC0373, TC0117, TC0066 & TC0396) to H-2(d) and 5 (TC0512, TC0177, TC0589, TC0794 & TC0596) to H-2(k) haplotypes respectively. Interestingly, H-2(b) was negatively associated with antibody responses to most of the antigens that were positively linked to H-2(d) or H-2(k) haplotypes. These results by mapping Chlamydia trachomatis antigens commonly recognized by mice with different strain background and H-2 genes and revealing antigen association with H-2 haplotypes have provided important information for developing chlamydial subunit vaccines and understanding chlamydial pathogenesis.

Abstract
Tumors develop with dysregulated activation of mammalian target of rapamycin (mTOR), the kinase activity of which is kept in an inactive state by a tumor suppressor dimer containing tuberous sclerosis 1 (TSC1) and TSC2. We examined whether conditional deletion of TSC1 by a knock-in allele of the anti-Müllerian hormone type 2 receptor (Amhr2) driving Cre expression and subsequent activation of mTOR in granulosa cells and in oviductal and uterine stromal cells affects fertility in female mice. Increased phosphorylation of ribosomal protein S6, a downstream target of activated mTOR, was observed in all AMHR2-expressing tissues examined, indicating loss of TSC1 activity. TSC1 deletion in granulosa cells led to the detection of significantly fewer primordial follicles in mutant mice at 12 wk, suggesting premature ovarian insufficiency, which might be related to the significantly increased time mutant mice spent in estrus. Although the number of good-quality ovulated oocytes was not significantly different compared with controls, there was a significantly higher number of degenerated oocytes after normal and superovulation, suggesting compromised oocyte quality, as well. Natural mating also showed severalfold higher numbers of degenerate bodies in the mutants that collected in bilateral swellings resembling hydrosalpinges that formed in all mice examined because of occlusion of the proximal oviduct. Attempts to transfer control embryos into mutant uteri also failed, indicating that implantation was compromised. Endometrial epithelial cells continued to proliferate, and quantitative RT-PCR showed that mucin 1 expression persisted during the window of implantation in mutant uteri, without any changes in progesterone receptor mRNA expression, suggesting a mechanism that does not involve disrupted estradiol-regulated progesterone receptor expression. Homozygous deletion of TSC1 in reproductive tract somatic tissues of mice rendered females completely infertile, which is likely due to these pleiotropic effects on follicle recruitment, oviductal development, and blastocyst implantation.

Abstract
Urogenital infection with Chlamydia trachomatis in some women can lead to upper genital tract pathologies, such as hydrosalpinx, potentially affecting fertility. In the current study, 27 of 40 mice intravaginally infected with Chlamydia muridarum developed visible hydrosalpinges in the oviduct while the remaining 13 did not, although all infected mice displayed similar infection time courses. Antisera from the 40 mice recognized 130 out of 257 C. muridarum proteins as antigens and 17 as immunodominant antigens. Importantly, the 27 mice with hydrosalpinges preferentially recognized two C. muridarum proteins (TC0582 and TC0912, designated pathology-associated antigens) while the 13 mice with no hydrosalpinx preferentially recognized 10 proteins (TC0047, TC0117, TC0190, TC0197, TC0257, TC0279, TC0326, TC0630, TC0689, and TC0816, designated nonpathology antigens). The preferential recognition was validated by absorption and independently confirmed in Western blots. The C. trachomatis homolog of TC0912 is encoded by a highly polymorphic gene that is associated with ocular pathogenesis. A fragment of TC0912 was found to improve the differentiation of hydrosalpinx from nonhydrosalpinx mice. TC0582 is a highly conserved ATP synthase, and it may contribute to chlamydial pathogenesis via mechanisms similar to those hypothesized for the highly conserved HSP60. Thus, we have identified chlamydial antigens and epitopes that are associated with either susceptibility or resistance to upper genital tract pathology, which will help us to further understand chlamydial pathogenesis and to develop anti-Chlamydia subunit vaccines.

Abstract
The molecular mechanisms controlling fluid secretion within the oviduct have yet to be determined. As in other epithelia, both secretory and absorptive pathways are likely to work in tandem to drive appropriate ionic movement to support fluid movement across the oviduct epithelium. This study explored the role of potassium channels in basolateral extracellular ATP (ATP(e))-stimulated ion transport in bovine oviduct epithelium using the Ussing chamber short-circuit current (I(SC)) technique. Basal I(SC) in bovine oviduct epithelium comprises both chloride secretion and sodium absorption and was inhibited by treatment with basolateral K(+) channel inhibitors tetrapentlyammonium chloride (TPeA) or BaCl(2). Similarly, ATP-stimulated chloride secretion was significantly attenuated by pretreatment with BaCl(2,) tetraethylammonium (TEA), tolbutamide, and TPeA. Basolateral K(+) current, isolated using nystatin-perforation technique, was rapidly activated by ATP(e), and pretreatment of monolayers with thapsigargin or TPeA abolished this ATP-stimulated K(+) current. To further investigate the type of K(+) channel involved in the ATP response in the bovine oviduct, a number of specific Ca(2+)-activated K(+) channel inhibitors were tested on the ATP-induced ΔI(SC) in intact monolayers. Charbydotoxin, (high conductance and intermediate conductance inhibitor), or paxilline, (high conductance inhibitor) did not significantly alter the ATP(e) response. However, pretreatment with the small conductance inhibitor apamin resulted in a 60% reduction in the response to ATP(e). The presence of small conductance family member KCNN3 was confirmed by RT-PCR and immunohistochemistry. Measurements of intracellular calcium using Fura-2 spectrofluorescence imaging revealed the ability of ATP(e) to increase intracellular calcium in a phospholipase C-inositol 1,4,5-trisphosphate pathway-sensitive manner. In conclusion, these results provide strong evidence that purinergic activation of a calcium-dependent, apamin-sensitive potassium conductance is essential to promote chloride secretion and thus fluid formation in the oviduct.

Abstract
OBJECTIVE To identify Chlamydia trachomatis antigens that can be used to differentially diagnose tubal factor infertility in comparison with previously reported heat shock protein 60. DESIGN In vitro study. SETTING Academic medical center. PATIENT(S) Infertile women with and without tubal pathology diagnosed laparoscopically. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Antibody responses to C. trachomatis in infertile women with or without tubal pathologies using a C. trachomatis genome-wide proteome array. RESULT(S) Comparison of the antibody profiles revealed 30 C. trachomatis antigens that were preferentially recognized in women with tubal factor infertility, with a detection sensitivity and specificity of 80.6% and 56.5%, respectively, 10 of which showed 100% specificity. A combination of CT443 and CT381 antigens yielded the highest detection sensitivity (67.7%) while maintaining 100% specificity. CONCLUSION(S) These findings have demonstrated that antibodies to CT443 and CT381, when used in combination, have higher sensitivity and specificity in predicting tubal factor infertility than other indicators for tubal factor infertility, such as heat shock protein 60 antibodies (35.5%, 100%) or hysterosalpingogram (65%, 83%). Using a panel of C. trachomatis antigens to serologically diagnose tubal factor infertility can save the patients from undertaking expensive and invasive procedures for determining tubal pathology and choosing treatment plans.

Abstract
PURPOSE To test the utility of three-dimensional (3D) ultrasound (US) inversion rendering technique in the evaluation of fluid-distended fallopian tubes. METHODS Fifty-two patients with fluid-filled adnexal masses suspected of being abnormal fallopian tubes were scanned by two-dimensional and 3D transvaginal ultrasound (TVUS). Six patients had bilateral disease. The acquired volumes were then "inverted" to display a cast-like appearance of the fluid-filled structures. The ipsilateral ovaries were identified in all patients. Five patients had acute tubal disease. RESULTS Fifty-two of the 58 inversion renderings yielded acceptable images of hydrosalpinges. Only in four patients were the two-dimensional images more informative than the 3D-rendered and inverted views. In nine patients adjacent corpora lutea, ovarian cysts, and follicles within normal ovaries were also identified, but appeared separate from the fluid-filled tubes. The tubes in the patients with acute disease were all successfully inverted. CONCLUSIONS The 3D inversion technique is a simple and effective way to render fluid-filled spaces, which may be tortuous and follow various directions. The rendered images increased the confidence in diagnosing hydrosalpinx.

Abstract
OBJECTIVES To compare the expression of pinopodes, LIF, integrin beta(3) and MUC1 in the peri-implantation endometrium of women with and without hydrosalpinx. STUDY DESIGN A prospective observational study in an assisted reproductive unit in a university teaching hospital, including 20 women with hydrosalpinx and 21 women without hydrosalpinx. Endometrial biopsies were performed on day LH+7 or +8. The proportion and density of pinopodes were assessed by scanning electron microscopy. LIF, integrin beta3 and MUC1 were evaluated with immunohistochemical staining. RESULTS The proportion and the density of pinopodes were not significantly different between the hydrosalpinx and control groups. The LIF, integrin beta(3), and MUC1 expression were significantly reduced in both glandular epithelial cells and endometrial lumen of the hydrosalpinx group when compared with those of the control group. The expression of integrin beta(3) in stromal cells was also significantly lower in the hydrosalpinx group. CONCLUSIONS The proportion and the density of pinopodes in the peri-implantation endometrium were not affected by the presence of hydrosalpinx while LIF, integrin beta(3) and MUC1 were significantly reduced in patients with hydrosalpinx.

Abstract
Ovulation is an essential physiological process in sexual reproduction; however, the underlying cellular mechanisms are poorly understood. We have previously shown that OAMB, a Drosophila G-protein-coupled receptor for octopamine (the insect counterpart of mammalian norepinephrine), is required for ovulation induced upon mating. OAMB is expressed in the nervous and reproductive systems and has two isoforms (OAMB-AS and OAMB-K3) with distinct capacities to increase intracellular Ca2+ or intracellular Ca2+ and cAMP in vitro. Here, we investigated tissue specificity and intracellular signals required for OAMB's function in ovulation. Restricted OAMB expression in the adult oviduct epithelium, but not the nervous system, reinstated ovulation in oamb mutant females, in which either OAMB isoform was sufficient for the rescue. Consistently, strong immunoreactivities for both isoforms were observed in the wild-type oviduct epithelium. To delineate the cellular mechanism by which OAMB regulates ovulation, we explored protein kinases functionally interacting with OAMB by employing a new GAL4 driver with restricted expression in the oviduct epithelium. Conditional inhibition of Ca2+/Calmodulin-dependent protein kinase II (CaMKII), but not protein kinase A or C, in the oviduct epithelium inhibited ovulation. Moreover, constitutively active CaMKII, but not protein kinase A, expressed only in the adult oviduct epithelium fully rescued the oamb female's phenotype, demonstrating CaMKII as a major downstream molecule conveying the OAMB's ovulation signal. This is consistent with the ability of both OAMB isoforms, whose common intracellular signal in vitro is Ca2+, to reinstate ovulation in oamb females. These observations reveal the critical roles of the oviduct epithelium and its cellular components OAMB and CaMKII in ovulation. It is conceivable that the OAMB-mediated cellular activities stimulated upon mating are crucial for secretory activities suitable for egg transfer from the ovary to the uterus.

Abstract
BACKGROUND Genital Chlamydia (C) trachomatis infection has been recognized as the single most common cause of pelvic inflammatory disease leading to severe tubal damage, ectopic pregnancy, infertility and hydrosalpinx. However, the mechanism underlying the formation of hydrosalpinx induced by C. trachomatis infection remains largely unknown. We performed this study to determine the involvement of cystic fibrosis transmembrane conductance regulator (CFTR), a cAMP-activated chloride channel that regulates epithelial electrolyte and fluid secretion, in hydrosalpinx fluid formation. METHODS Western blot analysis was used to determine CFTR expression in the hydrosalpinges that were seen on the ultrasound scans of infertile assisted reproduction treatment patients. Correlation with C. trachomatis infection was done by testing patients' sera for C. trachomatis immunoglobulin G antibody titer using a Capita enzyme-linked immunosorbent assay based kit. CFTR involvement was further verified in a rat C. trachomatis infection model and confirmed using CFTR mutant (CFTR(tm1Unc)) mice. RESULTS Here we report on the up-regulated expression of CFTR in the hydrosalpinx tissues of infertile patients with detectable serum levels of C. trachomatis antibody (immunoglobulin G). In a rat model, increased CFTR expression and fluid accumulation could be observed in the uterine horns infected with C. trachomatis elementary bodies, which was reversed by antibiotics treatment. In C. trachomatis-infected CFTR(tm1Unc) mice, however, no detectable fluid accumulation was observed. CONCLUSION These findings suggest the involvement of CFTR in the pathogenesis of hydrosalpinx fluid formation and may provide grounds for a better treatment strategy to improve assisted reproduction treatment outcome in infertile patients with hydrosalpinx.

Abstract
Infertility is commonly associated with cystic fibrosis (CF). Although infertility in men with CF has been thoroughly investigated, the infertility observed in women with CF has not been well studied. To investigate female infertility associated with CF, we used two independently derived mouse models of CF. Both of these models displayed decreased fertility characterized by a reduction in litter number and litter size. Our findings suggest that much of the reduced fertility in these mice originates from decreased fertilization due to inadequate sperm transport within the female reproductive tract. However, our data indicate that additional reproductive phenotypes in the CF female mice also contribute to the reduced fertility including small ovarian and uterine size, aberrant estrous cycles, and decreased oocyte ovulation rates. These data, along with previous work demonstrating that the gene mutated in CF, the cystic fibrosis transmembrane conductance regulator (CFTR), is normally expressed in tissues vital to reproduction, raises the possibility that CFTR may have a direct effect on fertility. If so, CFTR may also play an important role in normal female fertility within the general population.

Abstract
PURPOSE OF REVIEW Patients with hydrosalpinx are a recognized group with poor prognosis in in-vitro fertilization. This review presents evidence for the effectiveness of different treatment options. RECENT FINDINGS Theories explaining the mechanisms behind the impaired outcome of in-vitro fertilization still focus on the hydrosalpingeal fluid. Gamete and embryotoxic effects have been demonstrated, but it is not a consistent finding. Endometrial receptivity may be altered by the reduced expression of cytokines and integrins important to implantation, and reduced endometrial and subendometrial blood flows may play a role. The rationale for treatments to improve the results of in-vitro fertilization is based on interruption of the leakage of hydrosalpinx fluid into the uterine cavity. Laparoscopic salpingectomy has been evaluated in a large randomized trial and proved effective in restoring birth rates. Proximal tubal ligation may also be effective according to one smaller randomized trial. Other suggested methods such as transvaginal drainage have been poorly investigated. SUMMARY Pre-in-vitro fertilization salpingectomy is the only method that has proved effective in restoring birth rates in patients with hydrosalpinx. The underlying mechanism explaining reduced implantation and embryo development awaits further research.

Abstract
OBJECTIVE To describe a case report of hydrosalpinx that changed dramatically in size during the menstrual cycle. DESIGN Case report. SETTING University teaching hospital reproductive endocrinology and infertility practice. PATIENT(S) A 32-year-old woman with a history of medical and surgical treatments of endometriosis who sought infertility treatment. INTERVENTION(S) Transvaginal ultrasonography performed sequentially during menstrual cycles. MAIN OUTCOME MEASURE(S) Size of hydrosalpinx-like image. RESULT(S) The size of the hydrosalpinx-like image in the left adnexal region varied; it peaked during the ovulatory period and then remarkably diminished in a cyclic manner. Laparoscopy revealed a dense adhesion between the left tubal fimbriated end and the posterior uterine wall, which led to terminal obstruction of the tube. CONCLUSION(S) Change in the volume of the hydrosalpinx in this case was speculated to reflect the normal tubal fluid production regulated by ovarian hormones.

Abstract
Hydrosalpinx is a condition where the fallopian tube becomes obstructed and fills with fluid. Bilateral hydrosalpinx is most commonly associated with a pelvic infection. However, there may also be an association between partial hysterectomy and hydrosalpinx, which typically presents unilaterally. Although it is often difficult to visualize a normal fallopian tube, endovaginal sonography has proven to be a useful tool in the visualization and diagnosis of hydrosalpinx and other fallopian tube abnormalities. It is important to consider hydrosalpinx in the differential diagnosis when presented with a patient with a history of partial hysterectomy with associated pelvic pain. This case presents a woman with severe right lower quadrant pain with a history of partial hysterectomy. A pelvic sonogram revealed evidence of a unilateral hydrosalpinx. Postsurgical findings confirmed the diagnosis of right-sided hydrosalpinx and pelvic adhesions.

Abstract
Hydrosalpinx is a common cause of female infertility. Lower implantation and pregnancy rates have been reported in women with hydrosalpinges. How hydrosalpinx exerts its negative effect on the implantation process is not clearly understood. Mechanical factors, toxicity of the hydrosalpingeal fluid, and receptivity dysfunction may explain the impaired IVF outcome in the presence of hydrosalpinx. Laparoscopic surgery has a place in the diagnosis and management of hydrosalpinx. Analysis of the results of laparoscopic management of hydrosalpinx underscores the positive role of laparoscopy in fertility outcomes in women with this pathological tubal disease. Laparoscopic salpingectomy should be offered in those women who have bilateral disease or in cases where hydrosalpinges are large enough to be visible on ultrasound. Further randomized trials are required to assess other surgical treatment options for hydrosalpinx, such as laparoscopic salpingostomy, laparoscopic or hysteroscopic tubal occlusion, and drainage of hydrosalpinx before or during oocyte retrieval.

Abstract
There is currently no licensed vaccine against Chlamydia trachomatis, the leading cause of sexually transmitted bacterial disease worldwide. Conventional vaccination attempts using surface-exposed chlamydial antigens have achieved only partial success. We have employed a novel vaccination strategy using a secreted protein, chlamydial protease-like activity factor (CPAF), which has been shown to degrade host major histocompatibility complex transcription factors and keratin-8 and therefore may allow immune evasion and establishment of a productive infection. Intranasal immunization using recombinant CPAF (rCPAF) plus interleukin-12 (IL-12) (rCPAF+IL-12 immunization) was used to assess the protective immunity against genital Chlamydia muridarum infection in BALB/c mice. rCPAF+IL-12 immunization induced robust gamma interferon (IFN-gamma) production and minimal IL-4 production by splenocytes upon in vitro recall with rCPAF. The total and immunoglobulin G2a (IgG2a) anti-rCPAF antibody levels in serum were significantly elevated after rCPAF+IL-12 vaccination, as were the total antibody, IgG2a, and IgA levels in bronchoalveolar lavage and vaginal fluids when the animals were compared to animals that received rCPAF alone. rCPAF+IL-12-vaccinated mice displayed significantly reduced bacterial shedding upon chlamydial challenge and accelerated resolution of infection compared to mock-immunized (phosphate-buffered saline) animals. Moreover, rCPAF+IL-12-immunized animals exhibited protection against pathological consequences of chlamydial infection, including the development of hydrosalpinx and oviduct dilatation. This vaccination regimen also reduced the development of fibrosis and the influx of neutrophils into the upper genital tract when the animals were compared to mock-immunized (phosphate-buffered saline) animals after bacterial challenge. rCPAF+IL-12-mediated resolution of the bacterial infection and protection against Chlamydia-induced inflammatory disease were highly dependent on endogenous IFN-gamma production. Together, these results demonstrate that secreted chlamydial antigens may be novel vaccine candidates to induce protective immunity.

Abstract
PURPOSE OF REVIEW The clinical management of hydrosalpinges in infertile patients remains a contentious issue. This review aims to provide a critical analysis on the available treatments for hydrosalpinges, which have recently created a fierce debate between the promoters of salpingectomy and in-vitro fertilization and those who endorse tubal surgery. RECENT FINDINGS Hydrosalpinges have a detrimental effect on the outcome of in-vitro fertilization yet their mechanism is still unclear. Salpingectomy prior to in-vitro fertilization restores the likelihood of a successful outcome in a well defined group of patients with ultrasound-visible hydrosalpinges. However, not every woman with large hydrosalpinges should undergo salpingectomy as some fallopian tubes may be amenable to surgical repair. Preserved tubal mucosa indicates a good prognosis for tubal surgery, therefore an appropriate mucosal assessment should be routine prior to deciding upon further management. SUMMARY As salpingectomy is a definitive procedure it should be performed when the hydrosalpinges are beyond repair or in cases of in-vitro fertilization failure. Tubal surgery should be preferred to salpingectomy in mild to moderate tubal disease. A comparative study of restorative tubal surgery versus salpingectomy and in-vitro fertilization in selected women with hydrosalpinges is needed and will significantly help this debate. Prophylactic salpingectomy prior to in-vitro fertilization and tubal surgery is not competing but complementary in the treatment of hydrosalpinges-related infertility.

Abstract
Hydrosalpinx is one of the predisposing factors of adnexal torsion. However, because the incidence of hydrosalpinx in adolescent virgin patients is very rare, it may cause diagnostic dilemma, leading sometimes to suboptimal treatment. We present the case of an 18-yr-old female, not sexually active, presenting with acute lower right abdominal pain. The working diagnosis was of a simple ovarian cyst, so aspiration was performed. Abdominal symptoms reoccurred and sonography revealed a large hemorrhagic cystic mass adjacent to an edematous right ovary. The patient was referred to immediate laparoscopy due to suspected right adnexal torsion. On laparoscopy, the right adnexa was twisted three times causing an edematous ovary with a hematosalpinx. Detorsion was performed. Five weeks later, transabdominal ultrasound reviled normal bilateral ovaries and the hematosalpinx disappeared. In conclusion, hydrosalpinx, although very rare in adolescence, must be considered in the differential diagnosis. Aspiration in such cases is not the treatment of choice and moreover, it may cause complications.

Abstract
OBJECTIVE To compare endometrial and subendometrial blood flows among patients with and without hydrosalpinx (HSP) during in vitro fertilization treatment as measured by a three-dimensional power Doppler ultrasound. DESIGN A prospective observational study. SETTING A tertiary assisted-reproduction unit. PATIENT(S) Twenty-one patients with HSP were compared with 42 matched controls without HSP. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Endometrial thickness, endometrial pattern, endometrial volume, pulsatility index (PI) and resistance index (RI) of uterine vessels, and the vascularization index (VI), flow index (FI), and vascularization flow index (VFI) of endometrial and subendometrial regions were measured on the day of oocyte retrieval. RESULT(S) The proportion of the non-multilayered endometrial pattern was significantly higher in the HSP group than in the non-HSP group. Patients in the HSP group had significantly lower endometrial and subendometrial VI and VFI. Endometrial thickness, endometrial volume, uterine PI, uterine RI, and endometrial and subendometrial FI were similar between the two groups. No significant differences were observed in endometrial and subendometrial VI, FI, and VFI among patients with unilateral and bilateral HSP. CONCLUSION(S) A change in endometrial pattern and a decrease in endometrial and subendometrial blood flows may be the reasons for impaired implantation in patients with HSP.

MAIN OUTCOME MEASURE(S) Histologic score (HSCORE) on luminal and glandular endometrium of the patients with hydrosalpinx or tubal phimosis and the normal fertile controls. RESULT(S) The median (+/-SEM) HSCORE for beta3 subunit expression in endometrial glands was 0.39 +/- 0.23 and 0.42 +/- 0.18 for tubal phimosis and hydrosalpinx, respectively, and 1.74 +/- 0.26 for fertile controls. The median HSCORE for beta3 subunit expression in luminal epithelium for tubal phimosis, hydrosalpinx, and fertile controls was 0.07 +/- 0.06, 0.21 +/- 0.18, and 1.03 +/- 0.31, respectively. No statistical difference was observed on the expression of alpha1 integrin subunit expression between the three groups. CONCLUSION(S) The endometrial expression of beta3 integrin subunit is reduced in the presence of tubal phimosis or hydrosalpinx, during the window of implantation.

Abstract
BACKGROUND Hydrosalpinx (HSP), characterized by abnormal fluid accumulation in the Fallopian tube, is one of the main causes of infertility in women; however, the mechanism underlying the formation of hydrosalpinx fluid (HF) remains elusive. The present study investigated the possible involvement of cystic fibrosis transmembrane conductance regulator (CFTR), a cAMP-dependent chloride channel, in the pathogenesis of hydrosalpinx. METHODS Masson's trichrome staining was used to characterize epithelial transformation in human HSP; RT-PCR, immunohistochemistry and immunofluorescence staining were used for CFTR expression and localization. RESULTS Masson's trichrome staining showed areas of epithelial transformation, focally attenuated and pseudostratified. Immunostaining showed enhanced CFTR immunoreactivity in the focally attenuated and pseudostratified areas of HSP epithelium. RT-PCR revealed that CFTR expression in HSP was significantly greater than that in normal Fallopian tubes. CONCLUSIONS These results indicate that HSP epithelium undergoes epithelial transformation with elevated CFTR expression, which may lead to increased transepithelial electrolyte and fluid secretion resulting in HF formation. The present findings may lead to the development of new treatment strategies for infertile patients with HSP.

Abstract
Recurrent implantation failure is a distressing phenomenon, both for the infertile couple and for the physician responsible for their treatment. Aetiology is often not clear and treatment options are vague. Particularly when transferred embryos are of good quality, recurrent implantation failure may be attributed to less than optimal embryo transfer technique, pathological lesions of the uterine cavity, the presence of hydrosalpinges, fibroids and endometriosis. Poor embryo quality, especially when repetitive, is a major impediment to successful implantation and cannot be corrected at the present time. Molecular abnormalities at the endometrial level and abnormal embryo-endometrium dialogue may be responsible for some cases of recurrent implantation failure. Furthermore, there may be over- or under-expressed genes that may be related to successful implantation. At the present time, the physician confronted with a couple presenting with recurrent implantation failure should discuss openly the potential causes of this phenomenon, with special emphasis on correctable causes, and offer remedies that are evidence based.
