Efficacy of Hysteroscopy in Improving Fertility Outcomes in Women Undergoing Assisted Reproductive Technique: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

ABSTRACT:

Introduction

Usefulness of hysteroscopy before assisted reproductive technique (ART) was considered debatable. However, over the last decade, several new trials have been added to available literature. We aimed to assess the impact of diagnostic and operative hysteroscopy on reproductive outcomes of infertile women with and without intrauterine abnormalities.

Materials and methods

MEDLINE, Scopus, SciELO, Embase, Cochrane Library at CENTRAL, PROSPERO, CINAHL, grey literature, conference proceedings, and international controlled trials registries were searched without temporal, geographical, or language restrictions. Randomized controlled trials (RCTs) of infertile women comparing hysteroscopy versus no hysteroscopy prior to the first ART or after at least one failed attempt were included. RCTs of infertile women with intrauterine pathology comparing diagnostic versus operative hysteroscopy were included in separate analysis. Random-effect meta-analysis was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Grading of Recommendations, Assessment, Development and Evaluation and Cochrane criteria were used for quality of evidence and risk of bias assessment. Primary outcome was live birth rate (LBR). Secondary outcomes were clinical pregnancy (CPR) and pregnancy loss rate.

Results

Fifteen studies (5,038 women) were included. Compared to no hysteroscopy before first or after failed ART attempts, moderate-quality evidence showed that hysteroscopy increased the LBR (relative risk [RR] 1.24, 95% confidence interval [CI] 1.09-1.43, I2 = 21%), confirmed by subgroup analysis for women with failure after one or more ART cycles (RR 1.43, 95% CI: 1.19-1.72, I2 = 0%) but not before the first ART. Moderate-quality evidence showed that it increased the CPR (RR 1.36, 95% CI: 1.18-1.57; I2 = 51%), confirmed in subgroup analysis for both implantation failure (RR 1.40, 95% CI: 1.12-1.74, I2 = 52%) and before first ART (RR 1.32, 95% CI: 1.11-1.57, I2 = 42%). Low-quality data suggest that operative hysteroscopy increases CPR when used to treat intrauterine pathologies (RR 2.13, 95% CI: 1.56-2.92, I2 = 0%).

Conclusions

Although moderate-quality evidence supports performing hysteroscopy before ART in women with history of implantation failure, hysteroscopic evaluation of uterine cavity should be considered a first-line technique in all infertile women undergoing ART. Additional high-quality RCTs are still needed, particularly to assess yield during couple's initial evaluation even before ART is considered.

Project description:BackgroundVaccination against Coronavirus-19 disease (COVID-19) was widely administered from 2021 onwards. There is little information on how this vaccine affected fertility after assisted-reproductive-technology (ART). The aim of this study therefore was to determine if COVID-19 vaccination or time-since-vaccination influenced ART outcomes.Materials and methodsIn this prospective cohort study, 502 oocyte-retrieval-cycles and 582 subsequent embryo- transfer-cycles were grouped based on COVID-19 vaccine status of the female partner into those with no-exposure, 1-dose and ≥2-dose exposure. Within the exposed cohort, time-since-last-vaccination to embryotransfer- cycle (Ttr) was calculated in days. Main outcomes were mean-total-utilizable-embryos, mean-oocyteutilization- rates and cumulative-ongoing-pregnancy-rates per oocyte-retrieval-cycle, and ongoing-pregnancy and pregnancy-loss-rates per embryo-transfer cycle. The Beta-coefficient (ß) was calculated using linear regression for mean-total-utilizable-embryos and mean-oocyte-utilization-rates and adjusted-odds-ratio (OR) was calculated for cumulative-ongoing-pregnancy-rates, ongoing-pregnancy and pregnancy-loss-rates using binomial logistic regression. Influence of T(tr) on embryo-transfer outcomes was estimated using receiver-operator-curve (ROC) analysis and cut-offs determined that influenced embryo-transfer outcomes.ResultsMean-total-utilizable-embryos and mean-oocyte-utilization-rate per oocyte-retrieval-cycle in no-exposure, 1-dose and ≥2 dose were 2.7 ± 1.8 vs. 2.5 ± 1.9 vs. 2.7 ± 2.0, P=0.78, (ß=0.42, 95% confidence-interval (CI)=0.15 to 0.69) and 21.2 ± 13.2 vs. 25.1 ± 19.0 vs. 26.7 ± 18.8, P=0.08, (ß=3.94, 95% CI=1.26 to 6.23) respectively. Ongoing-pregnancy-rates and pregnancy-loss-rates per embryo-transfer-cycle were 27.3% vs. 24.4% vs. 32.5% (aOR=1.38, 95% CI=0.3-5.6, P=0.52), and 13.6% vs. 13.4% vs. 15.2%, (aOR=0.97, 95% CI=0.18-5.2, P=0.97) respectively. Cumulative-ongoing-pregnancy-rates per oocyte-retrieval-cycle were 36.5% vs. 34.5% vs. 35.5% (aOR=1.53, 95% CI=0.57 to 4.07, P=0.35). Median T(tr) was 146 days (IQR: 80-220). T(tr) negatively affected ongoing pregnancy rates for intervals <60 days (AUC=0.59, 95% CI=0.54-0.66, P<0.01). For T(tr) >60 vs. <60 days, the aOR for ongoing-pregnancy-per-embryo-transfer-cycle was 2.85 (95% CI=1.50-5.46, P<0.01).ConclusionCovid-19 vaccination does not negatively influence embryological-outcomes or cumulative-ongoing-pregnancies after ART-treatments. Duration since vaccination may have a weak negative effect on embryo-transfer-outcomes performed within 60 days.

Project description:BackgroundAir pollution exposure has been linked with diminished fertility. Identifying the metabolic changes induced by periconception air pollution exposure among women could enhance our understanding of the potential biological pathways underlying air pollution's reproductive toxicity.ObjectiveTo identify serum metabolites associated with periconception air pollution exposure and evaluate the extent to which these metabolites mediate the association between air pollution and live birth.MethodsWe included 200 women undergoing a fresh assisted reproductive technology (ART) cycle at Massachusetts General Hospital Fertility Center (2005-2015). A serum sample was collected during stimulation, and untargeted metabolic profiling was conducted using liquid chromatography with ultra-high-resolution mass spectrometry. Exposure to nitrogen dioxide (NO2), ozone (O3), fine particulate matter <2.5 µm (PM2.5), and black carbon (BC) was estimated using validated spatiotemporal models. Multivariable linear regression models were used to evaluate the associations between the air pollutants, live birth, and metabolic feature intensities. A meet in the middle approach was used to identify overlapping features and metabolic pathways.ResultsFrom the C18 and HILIC chromatography columns, 10,803 and 12,968 metabolic features were extracted. There were 190 metabolic features and 18 pathways that were significantly associated with both air pollution and live birth (P < 0.05) across chromatography columns. Eight features were confirmed metabolites implicated in amino acid and nutrient metabolism with downstream effects on oxidative stress and inflammation. Six confirmed metabolites fell into two intuitive clusters - "antioxidants" and "oxidants"- which could potentially mediate some of the association between air pollution and lower odds of live birth. Tryptophan and vitamin B3 metabolism were common pathways linking air pollution exposure to decreased probability of live birth.ConclusionHigher periconception air pollution exposure was associated with metabolites and biologic pathways involved in inflammation and oxidative stress that may mediate the observed associations with lower probability of live birth following ART.
