Abstract
BACKGROUND Hysteroscopic resection is the first-choice treatment for symptomatic type 0 and 1 fibroids. Traditionally, this was performed under general anesthesia. Over the last decade, surgical procedures are increasingly being performed in an outpatient setting under procedural sedation and analgesia. However, studies evaluating safety and effectiveness of hysteroscopic myomectomy under procedural sedation are lacking. This study aims to investigate whether hysteroscopic myomectomy under procedural sedation and analgesia with propofol is noninferior to hysteroscopic myomectomy under general anesthesia. METHODS AND FINDINGS This was a multicenter, randomized controlled noninferiority trial conducted in 14 university and teaching hospitals in the Netherlands between 2016 and 2021. Inclusion criteria were age ≥18 years, maximum number of 3 type 0 or 1 fibroids, maximum fibroid diameter 3.5 cm, American Society of Anesthesiologists class 1 or 2, and having sufficient knowledge of the Dutch or English language. Women with clotting disorders or with severe anemia (Hb < 5.0 mmol/L) were excluded. Women were randomized using block randomization with variable block sizes of 2, 4, and 6, between hysteroscopic myomectomy under procedural sedation and analgesia (PSA) with propofol or under general anesthesia (GA). Primary outcome was the percentage of complete resections, assessed on transvaginal ultrasonography 6 weeks postoperatively by a sonographer blinded for the treatment arm and surgical outcome. Secondary outcomes were the surgeon's judgment of completeness of procedure, menstrual blood loss, uterine fibroid related and general quality of life, pain, recovery, hospitalization, complications, and surgical reinterventions. Follow-up period was 1 year. The risk difference between both treatment arms was estimated, and a Farrington-Manning test was used to determine the p-value for noninferiority (noninferiority margin 7.5% of incomplete resections). Data were analyzed according to the intention-to-treat principle, including a per-protocol analysis for the primary outcome. A total of 209 women participated in the study and underwent hysteroscopic myomectomy with PSA (n = 106) or GA (n = 103). Mean age was 45.1 [SD 6.4] years in the PSA group versus 45.0 [7.7] years in the GA group. For 98/106 women in the PSA group and 89/103 women in the GA group, data were available for analysis of the primary outcome. Hysteroscopic resection was complete in 86/98 women (87.8%) in the PSA group and 79/89 women (88.8%) in the GA group (risk difference -1.01%; 95% confidence interval (CI) -10.36 to 8.34; noninferiority, P = 0.09). No serious anesthesiologic complications occurred, and conversion from PSA to GA was not required. During the follow-up period, 15 serious adverse events occurred (overnight admissions). All were unrelated to the intervention studied. Main limitations were the choice of primary outcome and the fact that our study proved to be underpowered. CONCLUSIONS Noninferiority of PSA for completeness of resection was not shown, though there were no significant differences in clinical outcomes and quality of life. In this study, hysteroscopic myomectomy for type 0 and 1 fibroids with PSA compared to GA was safe and led to shorter hospitalization. These results can be used for counseling patients by gynecologists and anesthesiologists. Based on these findings, we suggest that hysteroscopic myomectomies can be performed under PSA in an outpatient setting. TRIAL REGISTRATION The study was registered prospectively in the Dutch Trial Register (NTR 5357; registration date: 11 August 2015; Date of initial participant enrollment: 18 February 2016).

Abstract
STUDY OBJECTIVES To assess the effect of adenomyosis, endometriosis and combined adenomyosis and endometriosis, diagnosed on MRI, on IVF/ICSI outcomes versus male subfertility controls. STUDY DESIGN This single-centre matched retrospective cohort study was carried out at Catharina Hospital in Eindhoven, The Netherlands. The study group consisted of infertile women undergoing their first, fresh embryo transfer during IVF/ICSI, with adenomyosis only (N = 36), endometriosis only (N = 61), and combined adenomyosis and endometriosis (N = 93) based on MRI. The control group consisted of IVF/ICSI patients undergoing treatment due to male subfertility (N = 889). 1:2 case-control matching based on age during IVF/ICSI, parity and number of embryos transferred was performed. Odds ratios were calculated for biochemical pregnancy, ongoing pregnancy and live birth rate versus matched male subfertility controls, and were corrected for embryo quality. RESULTS Only the combined adenomyosis and endometriosis group showed a significantly reduced OR for biochemical pregnancy (p = 0.004, OR 0.453 (95% CI :(0.284-0.791)), ongoing pregnancy (p = 0.001, OR 0.302 (95% CI: (0.167-0.608)) and live birth (p = 0.001, OR 0.309 (95% CI: (0.168-0.644)) compared to matched male subfertility controls. CONCLUSIONS The lower (ongoing) pregnancy and live birth rates in the combined adenomyosis and endometriosis women can be attributed to more severe disease in these women, ultimately resulting in increased chances for failed implantation and miscarriage. This highlights the importance of screening for adenomyosis in endometriosis patients, and identifies these women target for additional (hormonal) treatment prior to IVF/ICSI.

Abstract
OBJECTIVE To assess the incidence of ovarian cancer in women with histologically proven endometriosis after bilateral salpingo-oophorectomy (BSO). DESIGN Retrospective nationwide cohort study. SETTING Dutch pathology database. PATIENT(S) Women with histologically proven endometriosis who had undergone BSO between 1990 and 2015 (n = 7,984). This study consists of 2 control cohorts: women with histologically proven endometriosis without BSO (n = 42,633) and women with a benign dermal nevus (n = 132,535). INTERVENTION(S) Observational study. MAIN OUTCOME MEASURE(S) Number of histologic diagnoses of (extra-)ovarian cancers. Incidence rate ratios (IRR) were estimated for (extra-)ovarian cancer. The number needed to treat was calculated. RESULT(S) We identified 9 (0.1%) (extra-)ovarian cancers in the BSO cohort and 170 (0.4%) and 444 (0.3%) ovarian cancers in the endometriosis and nevus control cohorts, respectively. We found an age-adjusted IRR of 0.34 (95% confidence interval [CI], 0.15-0.76) when the BSO cohort was compared with the endometriosis cohort. Comparing the BSO cohort with the nevus control cohort resulted in an age-adjusted IRR of 0.38 (95% CI, 0.17-0.85). The number needed to treat when the BSO cohort was compared with the endometriosis control cohort was 351 (95% CI, 272-591). CONCLUSION(S) In this nationwide study, we found that the (extra-)ovarian cancer incidence in women with histologically proven endometriosis decreased to less than the background population risk after BSO. Additionally, we found a significant reduction of the incidence of ovarian cancer when compared with women with histologically proven endometriosis without BSO. Endometriosis surgery could in the future be a preventive strategy in women with endometriosis and a high-risk profile for ovarian cancer.

Abstract
Women with histologically proven endometriosis/adenomyosis have an increased risk of ovarian cancer. Small studies show conflicting results on the endometrial cancer risk in women with endometriosis/adenomyosis. Therefore, we assessed the incidence of endometrial cancer in women with histologically proven endometriosis or adenomyosis. We performed a population-based retrospective cohort study of 129,862 women with histologically proven endometriosis/adenomyosis, matched with 132,700 women with a nevus selected from the Dutch pathology registry between 1990 and 2015. Histology results for endometrial cancer were retrieved. Crude and age-adjusted odds ratios for endometrial cancer were estimated. In the endometriosis/adenomyosis group, 1827 (1.4%) women had a histological report on endometrial cancer, and in the nevus group, 771 (0.6%) women. The age-adjusted OR for endometrial cancer was 2.58 (95%CI 2.37-2.81). After excluding the first year of follow-up, the age-adjusted OR was 0.76 (95%CI 0.63-0.92), indicating that endometrial cancer is most often found at time of histological diagnosis of endometriosis/adenomyosis. In around 20% of the endometrial cancer cases, the endometrial cancer was not recognized until after hysterectomy. Of these women, 35% had no prior (micro)curettage or biopsy. This study shows an increased incidence of endometrial cancer in women with histologically proven endometriosis and adenomyosis.

Abstract
OBJECTIVE Due to the evolution of hysteroscopic instruments, therapeutic hysteroscopic procedures are increasingly performed in an outpatient, office-based setting. The most important limiting factor of performing these hysteroscopic treatments is patient discomfort. Procedural Sedation Analgesia (PSA) decreases patient discomfort and anxiety. The main goal of this study is to determine safety, feasibility and patient satisfaction of therapeutic hysteroscopy performed under procedural sedation in an outpatient clinic. Our second objective was to compare 9 mm scopes with smaller diameter scopes. STUDY DESIGN All consecutive patients suitable for procedural sedation and scheduled for a therapeutic hysteroscopy in the outpatient clinic were prospectively included from February 2014 to November 2018 in a teaching hospital in the Netherlands. A variety of therapeutic hysteroscopies procedures was performed including myomectomy, removal of retained products of conception and endometrial ablation. Therapeutic hysteroscopes with 3.8 mm, 5 mm and 9 mm diameter were used. In all selected women procedure time, admission time, pain scores, anaesthesiologic and procedural complications were assessed. All women received a questionnaire on patient satisfaction. RESULTS In total 455 patients underwent a therapeutic hysteroscopy. Median procedure time was 11 min (2-63 min) and median admission time was 130 min (30-480 min). Median pain score according to the visual analog scale (VAS) before, during and after procedure were respectively 0 (0-10), 0 (0-4) and 0 (0-9). Anaesthesiologic complication rate was 4.4 %, all minor. Procedural complications consisted of infection postoperatively (0.4 %), excessive blood loss during procedure (0.6 %) and perforation (0.4 %). Procedure was incomplete in 3.3 % of all procedures. Patient satisfaction was high, as 96 % of the women were satisfied. No differences were found in pain scores, VAS 0 versus 1 after the procedure, between 3.8 or 5 mm and 9 mm scopes. CONCLUSION It is safe and feasible to perform a therapeutic hysteroscopy under procedural sedation in an outpatient setting, with low pain scores and a high degree of patient satisfaction, also when large diameter instruments are used.

Abstract
INTRODUCTION Magnetic resonance imaging (MRI) diagnosis of adenomyosis is considered the most accurate non-invasive technique, but remains subjective, with no consensus on which diagnostic parameters are most accurate. We aimed to systematically review the literature on how adenomyosis can be objectively quantified on MRI in a scoping manner, to review the diagnostic performance of these characteristics compared with histopathological diagnosis, and to summarize correlations between measures of adenomyosis on MRI and clinical outcomes. MATERIAL AND METHODS We searched databases Pubmed, Embase, and Cochrane for relevant literature up to April 2020 according to PRISMA guidelines. We included studies that objectively assessed adenomyosis on MRI, and separately assessed studies investigating the diagnostic performance of MRI vs histopathology for inclusion in a meta-analysis. The QUADAS-2 tool was used for risk of bias, with many studies showing an unclear or high risk of bias. RESULTS Eighty studies were included, of which 14 assessed the diagnostic performance of individual MRI parameters, with four included in the meta-analysis of diagnostic accuracy. Common MRI parameters were: junctional zone (JZ) characteristics, such as maximum JZ thickness-pooled sensitivity 71.6% (95% CI 46.0%-88.2%), specificity 85.5% (52.3%-97.0%); JZ differential-pooled sensitivity 58.9% (95% CI 44.3%-72.1%), specificity 83.2% (95% CI 71.3%-90.8%); and JZ to myometrial ratio-pooled sensitivity 63.3% (95% CI 51.9%-73.4%), specificity 79.4% (95% CI 42.0%-95.4%); adenomyosis lesion size, uterine morphology (pooled sensitivity 42.9% (95% CI 15.9%-74.9%), specificity 87.7%, (95% CI 37.9-98.8) and changes in signal intensity-eg, presence of myometrium cysts; pooled 59.6% (95% CI 41.6%-75.4%) and specificity of 96.1% (95% CI 80.7%-99.3%). Other MRI parameters have been used for adenomyosis diagnosis, but their diagnostic performance is unknown. Few studies attempted to correlate adenomyosis MRI phenotype to clinical outcomes. CONCLUSIONS A wide range of objective parameters for adenomyosis exist on MRI; however, in many cases their individual diagnostic performance remains uncertain. JZ characteristics remain the most widely used and investigated with acceptable diagnostic accuracy. Specific research is needed into how these objective measures of adenomyosis can be correlated to clinical outcomes.

Abstract
BACKGROUND Several studies have suggested that endometriosis is associated with an increased risk of ovarian cancer, especially for the clear-cell and endometrioid subtypes. However, previous studies lack sufficient power or diagnostic certainty. OBJECTIVE The objective of the study was to assess the association between histologically proven endometriosis and ovarian cancer in a large population-based cohort study. STUDY DESIGN We identified 131,450 women with a histological diagnosis of endometriosis between 1990 and 2015 from the Dutch nationwide registry of histopathology and cytopathology (PALGA). For the control cohort 132,654 women with a benign dermal nevus were matched on age and inclusion year with the endometriosis cases. Histological diagnoses of ovarian, fallopian tubes, and peritoneal cancers between January 1990 and July 2017 were retrieved. Incidence rate ratios were estimated for ovarian cancer and its subtypes for the whole follow-up period as well as for women with more than 1 person-year at risk. RESULTS We found a crude incidence rate ratio of 4.79 (95% confidence interval, 4.33-5.31) and an age-adjusted incidence rate ratio of 7.18 (95% confidence interval, 6.17-8.36) for ovarian cancer overall. Endometrioid and clear-cell ovarian cancer had the highest age-adjusted incidence rate ratio of 29.06 (95% confidence interval, 20.66-40.87) and 21.34 (95% confidence interval, 14.01-32.51), respectively. Median age at ovarian cancer diagnosis was 56 years (interquartile range, 49-63) for the endometriosis cohort and 60 years (interquartile range, 53-67) for the nevus cohort, (P < .05). After excluding women with less than 1 person-year at risk following an endometriosis diagnosis, we found a crude incidence rate ratio of 1.04 (95% confidence interval, 0.91-1.19) and an age-adjusted incidence rate ratio of 1.08 (95% confidence interval, 0.87-1.35) for ovarian cancer overall. However, statistically significant age-adjusted incidence rate ratios of 2.29 (95% confidence interval, 1.24-4.20) for clear-cell ovarian cancer and 2.56 (95% confidence interval, 1.47-4.47) for endometrioid ovarian cancer were found. CONCLUSION A significantly higher incidence of clear-cell and endometrioid ovarian cancer was found in women with histologically proven endometriosis. Additionally, we found an increased incidence of all ovarian cancer subtypes in histologically proven endometriosis; however, in many of these women, endometriosis and ovarian cancer were diagnosed synchronously after the average menopausal age, which may suggest that the risk of ovarian cancer in endometriosis patients remains, even when clinical endometriosis symptoms are no longer present.

Abstract
BACKGROUND In women with abnormal uterine bleeding, fibroids are a frequent finding. In case of heavy menstrual bleeding and presence of submucosal type 0-1 fibroids, hysteroscopic resection is the treatment of first choice, as removal of these fibroids is highly effective. Hysteroscopic myomectomy is currently usually performed in the operating theatre. A considerable reduction in costs and a higher patient satisfaction are expected when procedural sedation and analgesia with propofol (PSA) in an outpatient setting is applied. However, both safety and effectiveness - including the necessity for re-intervention due to incomplete resection - have not yet been evaluated. METHODS This study is a multicentre randomised controlled trial with a non-inferiority design and will be performed in the Netherlands. Women > 18 years with a maximum of 3 symptomatic type 0 or 1 submucosal fibroids with a maximum diameter of 3.5 cm are eligible to participate in the trial. After informed consent, 205 women will be randomised to either hysteroscopic myomectomy using procedural sedation and analgesia with propofol in an outpatient setting or hysteroscopic myomectomy using general anaesthesia in a clinical setting in the operating theatre. Primary outcome will be the percentage of complete resections, based on transvaginal ultrasonography 6 weeks postoperatively. Secondary outcomes are cost effectiveness, menstrual blood loss (Pictorial blood assessment chart), quality of life, pain, return to daily activities/work, hospitalization, (post) operative complications and re-interventions. Women will be followed up to one year after hysteroscopic myomectomy. DISCUSSION This study may demonstrate comparable effectiveness of hysteroscopic myomectomy under procedural sedation and analgesia versus general anaesthesia in a safe and patient friendly environment, whilst achieving a significant cost reduction. TRIAL REGISTRATION Dutch trial register, number NTR5357 . Registered 11th of August 2015.

Abstract
Female sterilization is the most popular and common contraceptive method worldwide. Because hysteroscopic sterilization techniques are used less often due to side effects, the number of laparoscopic sterilization is increasing. A systematic overview concerning the most optimal anesthetic technique for laparoscopic sterilization is lacking. We performed a systematic review to compare conscious sedation with general anesthesia for laparoscopic sterilization procedures with respect to clinical relevant outcome measures, such as operating times, perioperative parameters and complications, patient comfort, recovery, and patient satisfaction. We searched Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE for randomized controlled trials comparing general anesthesia with conscious sedation for laparoscopic sterilization. Two authors (AGH and HAAMvV) abstracted and entered data into RevMan. Methodologic quality of the included trials was critically appraised. For our main outcome measures mean differences (continuous variables) and risk ratios (dichotomous variables) with 95% confidence intervals using random-effect models were calculated. Four randomized controlled trials were included comparing general anesthesia versus local anesthesia with conscious sedation for laparoscopic sterilization. The methodologic quality of the studies was moderate to good. Both techniques were comparable with regard to operating times, complications, and postoperative pain. However, local anesthesia with conscious sedation showed better results compared with general anesthesia with respect to recovery times, patient complaints of sore throat, and patient recovery and satisfaction. In conclusion, this systematic review about anesthetic techniques for laparoscopic sterilization showed that both general anesthesia and conscious sedation have no major anesthetic complications and may therefore be safe. Patients might benefit from conscious sedation in terms of recovery times, sore throat, and patient recovery and satisfaction, but only a few studies are included in the review and are relatively old. New research regarding this subject is needed to advise our patients most optimally in the future about the best anesthetic technique to be used when choosing for a laparoscopic sterilization procedure.

Abstract
STUDY OBJECTIVE To compare hysteroscopic morcellation with loop resection for the removal of placental remnants in terms of procedure time, adverse events, tissue availability, histology results, short-term effectiveness, and postoperative adhesions. DESIGN A randomized controlled trial (Canadian Task Force classification I). SETTING A teaching and university hospital. PATIENTS Women with placental remnants. INTERVENTIONS Hysteroscopic morcellation with the TRUCLEAR 8.0 Tissue Removal System (Smith & Nephew, Inc, Andover, MA) or loop resection with a rigid 8.5-mm bipolar resectoscope (Karl Storz GmbH, Tuttlingen, Germany). MEASUREMENTS AND MAIN RESULTS Forty-six and 40 women were included in the hysteroscopic morcellation and resection groups, respectively. The median operating time was significantly shorter for hysteroscopic morcellation compared with loop resection (6.2 minutes [interquartile range, 4.0-11.2 minutes] vs 10.0 minutes [5.8-16.4 minutes], p = .023). Both operating time and total procedure time, corrected for the diameter of the placental remnants, were significantly reduced for hysteroscopic morcellation compared with loop resection, by 40% (95% confidence interval, 15%-58%; p = .005) and 22% (95% CI, 5%-37%; p = .014), respectively. No adverse events occurred during hysteroscopic removal. Perforation at dilation in 8 cases of the hysteroscopic morcellation group resulted in 2 procedure discontinuations and 1 incomplete procedure. Incomplete removal was found in 1 uncomplicated hysteroscopic morcellation procedure and 2 resection procedures. Pathology results confirmed the presence of placental remnants in 27 of 40 (67.5%) and 26 of 37 (70%) patients in the hysteroscopic morcellation and resection groups, respectively. Second-look hysteroscopy showed de novo intrauterine adhesions in 1 of 35 patients (3%) in the hysteroscopic morcellation group and 1 of 30 (3%) patients in the resection group. CONCLUSION Hysteroscopic morcellation is a faster alternative than loop resection. Both techniques are safe and show high rates of complete removal and tissue availability and low rates of de novo intrauterine adhesions.

Abstract
BACKGROUND Heavy menstrual bleeding is an important health problem. Two frequently used therapies are the levonorgestrel intra-uterine system (LNG-IUS) and endometrial ablation. The LNG-IUS can be applied easily by the general practitioner, which saves costs, but has considerable failure rates. As an alternative, endometrial ablation is also very effective, but this treatment has to be performed by a gynaecologist. Due to lack of direct comparison of LNG-IUS with endometrial ablation, there is no evidence based preferred advice for the use of one of these treatment possibilities. METHOD/DESIGN A multicenter randomised controlled trial, organised in a network infrastructure in the Netherlands in which general practitioners and gynaecologists collaborate. DISCUSSON This study, considering both effectiveness and cost effectiveness of LNG-IUS versus endometrial ablation may well improve care for women with heavy menstrual bleeding.

Abstract
Use of combined oral contraceptives is associated with a three- to six-fold increased risk of venous thrombosis. Hormonal contraceptives induce acquired resistance to activated protein C (APC), which predicts the risk of venous thrombosis. The biological basis of the acquired APC resistance is unknown. Free protein S (PS) and free tissue factor pathway inhibitor (TFPI) are the two main determinants of APC. Our objective was to assess the effect of both hormonal and non-hormonal contraceptives with different routes of administration on free TFPI and free PS levels. We conducted an observational study in 243 users of different contraceptives and measured APC sensitivity ratios (nAPCsr), free TFPI and free PS levels. Users of contraceptives with the highest risk of venous thrombosis as reported in recent literature, had the lowest free TFPI and free PS levels, and vice versa, women who used contraceptives with the lowest risk of venous thrombosis had the highest free TFPI and free PS levels. An association was observed between levels of free TFPI and nAPCsr, and between free PS and nAPCsr. The effect of oral contraceptives on TFPI and PS is a possible explanation for the increased risk of venous thrombosis associated with oral contraceptives.

Abstract
Exogenously administered estrogens and progestogens as during combined oral contraceptive use increase the risk of venous thrombosis. The thrombin generation-based APC resistance assay is a global coagulation test that enables quantification of the net prothrombotic effect of combined oral contraceptives and that predicts the risk of thrombosis. The thrombotic risk of the levonorgestrel-releasing intrauterine system is unknown. It was the objective of this study to evaluate the thrombotic risk by comparing the APC resistance before and after insertion of a levonorgestrel-releasing or a copper-containing intrauterine device. We measured normalized APC-sensitivity ratios (nAPCsr) before and three months after insertion of the levonorgestrel-intrauterine system in 56 women and the copper-intrauterine device in 18 women. In women without hormonal contraceptive use or a pregnancy in the three months before collection of the baseline samples, nAPCsr were lower three months after insertion of the levonorgestrel-intrauterine system than at baseline (difference -0.29; 95% CI -0.04 to -0.53) and hardly changed after insertion of the copper-intrauterine device (difference -0.11; 95% CI -1.03 to 0.82). In women who switched from a combined oral contraceptive to the levonorgestrel-system the difference was more pronounced (-1.48; 95% CI -0.85 to -2.11). In this study we observed that the levonorgestrel-intrauterine system decreases the resistance to APC which indicates that the levonorgestrel-intrauterine system does not have a prothrombotic effect.

Abstract
In a study population consisting of healthy men (n = 8), women not using oral contraceptives (OC) (n = 28) and women using different kinds of OC (n = 187) we used calibrated automated thrombography (CAT) in the absence and presence of added activated protein C (APC) to compare parameters that can be obtained from thrombin generation curves, i.e. lag time, time to peak, peak height and endogenous thrombin potential (ETP). Both with and without APC, plasmas of OC users exhibited the shortest lag time and time to peak, and the highest peak height and ETP. In the absence of APC none of these parameters differed between users of OC containing different progestogens. In contrast, in the presence of APC shorter lag times and time to peak, and higher peak height and ETP were observed in plasma of users of gestodene-, desogestrel-, drospirenone- and cyproterone acetate-containing OC than in plasma of users of levonorgestrel- containing OC. The ETP determined in the absence of APC (ETP(-APC)) had no predictive value for the APCsr (r = 0.11; slope 0.9 x 10(-3); 95% CI: -0.1 x 10(-3) to 2.0 x 10(-3)) whereas the ETP measured in the presence of APC (ETP+APC) showed an excellent correlation with the APCsr (r = 0.95; slope 6.6 x 10(-3); 95% CI: 6.3 x 10(-3) to 6.9 x 10(-3)) indicating that the APCsr is entirely determined by the ETP+APC. In conclusion, OC use increases thrombin generation, but differential effects of second and third generation OCs on the protein C system likely determine the differences in the risk of venous thrombosis between these kinds of OC.

Abstract
UNLABELLED The postcoital test has poor diagnostic and prognostic characteristics. Nevertheless, some physicians believe it can identify scanty or abnormal mucus that might impair fertility. One way to avoid "hostile" cervical mucus is intrauterine insemination. With this technique, the physician injects sperm directly into the uterine cavity through a small catheter passed through the cervix; the theory is to bypass the "hostile" cervical mucus. Although most gynecologic societies do not endorse use of intrauterine insemination for hostile cervical mucus, some physicians consider it an effective treatment for women with infertility thought the result of cervical mucus problems. The aim of this review was to determine the effectiveness of intrauterine insemination with or without ovarian stimulation in women with cervical hostility who failed to conceive.We searched Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library Issue 2, 2005, MEDLINE (1966 to June 2005), EMBASE (1980 to June 2005), POPLINE (to June 2005), and LILACS (to June 2005). In addition, we contacted experts and searched the reference list of relevant articles and book chapters. We included randomized and quasirandomized, controlled trials comparing intrauterine insemination with intercourse timed at the presumed fertile period. Participants were women with cervical hostility who failed to conceive for at least 1 year. We assessed the titles and abstracts of 386 publications and 2 reviewers independently abstracted data on methods and results from 5 studies identified for inclusion. The main outcome is pregnancy rate per couple. We did not pool the outcomes of the included 5 studies in a meta-analysis resulting from the methodological quality of the trials and variations in the patient characteristics and interventions. Narrative summaries of the outcomes are provided. Each study was too small for a clinically relevant conclusion. None of the studies provided information on important outcomes such as spontaneous abortion, multiple pregnancies, and ovarian hyperstimulation syndrome. There is no evidence from the published studies that intrauterine insemination is an effective treatment for cervical hostility. Given the poor diagnostic and prognostic properties of the postcoital test and the observation that the test has no benefit on pregnancy rates, intrauterine insemination (with or without ovarian stimulation) is unlikely to be a useful treatment for putative problems identified by postcoital testing. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to recall that there is a lack of adequate studies that support that intrauterine insemination (IUI) is an effective treatment of cervical hostility, explain that the postcoital test has poor diagnostic and prognostic properties, and state that the use of both tests has no benefit on pregnancy rates. EDITOR'S NOTE Although many assisted reproductive technology (ART) programs no longer perform postcoital tests, many perform intrauterine insemination (IUI), often with gonadotropins or clomiphene citrate, in their subfertile patients. Therefore, this review article will be of value to our readers who treat subfertile patients with IUI, whether or not they perform postcoital tests.

Abstract
OBJECTIVE We investigated the frequency of quality assessment of randomized controlled trials within systematic reviews and the incorporation of the quality assessment in the analysis. STUDY DESIGN AND SETTING We included new systematic reviews of at least five trials of therapeutic or preventive interventions that appeared in issue 2, 2003, of the Cochrane Database of Systematic Reviews. All systematic reviews in the 2002 issues of the Annals of Internal Medicine, BMJ, JAMA, and Lancet were identified in Pubmed. All reviews were assessed under unblinded conditions using preprinted extraction forms. RESULTS Trial quality was assessed in all Cochrane reviews and most (74%) of the paper reviews. When we excluded 11 paper reviews that were also published as Cochrane review, the percentage remained similar (67%). Fifty percent of all Cochrane reviews and 61% of all paper reviews incorporated the results of the quality assessment in the analysis. CONCLUSION Half of the reviews did not incorporate the results of the quality assessment in the analysis. Authors, peer-reviewers, and editors should no longer focus exclusively on whether quality assessment has been performed but should also concentrate on incorporation of quality assessments in the analysis of the systematic review.

Abstract
BACKGROUND Epidemiological studies have shown that both the estrogen dose and progestogen type of oral contraceptives contribute to the increased risk of thrombosis in oral contraceptive users. Thrombin generation-based activated protein C (APC) sensitivity is a global test for the net prothrombotic effect of oral contraceptives and predicts the thrombotic risk. Our objective was to test the usefulness of sex hormone-binding globulin (SHBG) as a marker for the thrombotic risk of an oral contraceptive. METHODS We measured SHBG and APC resistance in 156 healthy users of various types of oral contraceptives. RESULTS Users of oral contraceptives with a moderately increased risk of thrombosis (gestodene and desogestrel pills) had higher SHBG levels than users of low-risk oral contraceptives containing levonorgestrel. Similarly, for higher doses of estrogen in oral contraceptives we found higher SHBG levels. Women using oral contraceptives with the highest thrombotic risk (cyproterone acetate pills) rendered the highest SHBG levels. Users of oral contraceptives containing gestodene, desogestrel or cyproterone acetate were more resistant to APC than users of levonorgestrel pills. SHBG levels were positively associated with the increased APC resistance. CONCLUSIONS Our findings support the hypothesis that the effect of an oral contraceptive on SHBG levels might be a marker for the thrombotic risk.
