Ulipristal acetate versus gonadotropin-releasing hormone agonists prior to laparoscopic myomectomy (MYOMEX trial): Long term results of a double-blind randomized controlled trial.

OBJECTIVE: The aim of this study was to compare the effect of ulipristal acetate (UPA) and gonadotropin-releasing hormone agonists (GnRHa) before laparoscopic myomectomy on long term secondary outcomes of the MYOMEX-trial, regarding quality of life, ultrasound characteristics, hemoglobin levels 6 weeks post-operative, sexual function and menstrual bleeding control. A cost-analysis was also performed. Short-term primary and secondary outcomes are reported elsewhere. STUDY DESIGN: A double-blind, randomized, controlled, non-inferiority trial in nine hospitals in the Netherlands. Participants were randomized in a 1:1 ratio (block size of four, stratified per hospital) to either UPA or GnRHa pre-treatment. Additional placebo injections containing saline, respectively daily placebo tablets were given to both groups to ensure double-blinding. Surgery was performed within a month after the last tablet. Women were followed up until six months post-surgery. RESULTS: A total of 55 participants were randomized: 30 to the UPA- and 25 to the GnRHa-group between May 2015 and July 2017. Uterine volume at six weeks post-operative did not differ significantly between both pre-treatment groups with 170.1 cm3 (106.8-243.5; N = 29) vs. 152.8 cm3 (92.3-205.6; N = 23) for the UPA- and GnRHa-group respectively (p = 0.423). Hemoglobin levels six weeks post-operatively recovered back to baseline and were not significantly different between groups with 7.7 mmol/L for the UPA- vs. 8.1 mmol/L for the GnRHa-group (p = 0.157; mean difference -0.4 (CI -0.9, 0.2). Menstrual bleeding pattern, quality of life, effects on general and sexual health showed a significant improvement compared to baseline in both groups without any differences between the treatment groups. Symptom severity scores also decreased significantly at 6 week post-operatively compared to baseline, but did not differ between the treatment groups. Fibroid characteristics at baseline (e.g. mean diameter of largest fibroid) appeared not to be a confounding factor. An exploratory cost analysis showed no significant differences in absenteeism costs, total healthcare and societal costs, after adjustment for confounding factors. CONCLUSION: Pre-treatment prior to laparoscopic myomectomy with UPA compared to GnRHa has similar effects on bleeding pattern, menopausal symptoms, sexual functioning, symptom severity and quality of life from baseline up to six months post-operative. Due to the small sample size, these findings should be interpreted with caution. Also, no firm conclusions on costs could be made.

A Novel Approach to Transmural Access to the Uterine Cavity in Cases of an Inaccessible Uterine Cavity: A Case Series.

Access to the uterine cavity can sometimes be a challenge or even impossible because of various causes such as prior surgery. We report our experience with a novel approach to this problem in 8 cases using ultrasound-guided transmural injection of dye; afterward, the cavity was successfully found in all cases by ultrasound-guided hysteroscopy following the colored epithelium.

Individualized versus standard FSH dosing in women starting IVF/ICSI: an RCT. Part 2: The predicted hyper responder.

STUDY QUESTION: Does a reduced FSH dose in women with a predicted hyper response, apparent from a high antral follicle count (AFC), who are scheduled for IVF/ICSI lead to a different outcome with respect to cumulative live birth rate and safety? SUMMARY ANSWER: Although in women with a predicted hyper response (AFC > 15) undergoing IVF/ICSI a reduced FSH dose (100 IU per day) results in similar cumulative live birth rates and a lower occurrence of any grade of ovarian hyperstimulation syndrome (OHSS) as compared to a standard dose (150 IU/day), a higher first cycle cancellation rate and similar severe OHSS rate were observed. WHAT IS KNOWN ALREADY: Excessive ovarian response to controlled ovarian stimulation (COS) for IVF/ICSI may result in increased rates of cycle cancellation, the occurrence of OHSS and suboptimal live birth rates. In women scheduled for IVF/ICSI, an ovarian reserve test (ORT) can be used to predict response to COS. No consensus has been reached on whether ORT-based FSH dosing improves effectiveness and safety in women with a predicted hyper response. STUDY DESIGN SIZE, DURATION: Between May 2011 and May 2014, we performed an open-label, multicentre RCT in women with regular menstrual cycles and an AFC > 15. Women with polycystic ovary syndrome (Rotterdam criteria) were excluded. The primary outcome was ongoing pregnancy achieved within 18 months after randomization and resulting in a live birth. Secondary outcomes included the occurrence of OHSS and cost-effectiveness. Since this RCT was embedded in a cohort study assessing over 1500 women, we expected to randomize 300 predicted hyper responders. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with an AFC > 15 were randomized to an FSH dose of 100 IU or 150 IU/day. In both groups, dose adjustment was allowed in subsequent cycles (maximum 25 IU in the reduced and 50 IU in the standard group) based on pre-specified criteria. Both effectiveness and cost-effectiveness were evaluated from an intention-to-treat perspective. MAIN RESULTS AND THE ROLE OF CHANCE: We randomized 255 women to a daily FSH dose of 100 IU and 266 women to a daily FSH dose of 150 IU. The cumulative live birth rate was 66.3% (169/255) in the reduced versus 69.5% (185/266) in the standard group (relative risk (RR) 0.95 [95%CI, 0.85-1.07], P = 0.423). The occurrence of any grade of OHSS was lower after a lower FSH dose (5.2% versus 11.8%, RR 0.44 [95%CI, 0.28-0.71], P = 0.001), but the occurrence of severe OHSS did not differ (1.3% versus 1.1%, RR 1.25 [95%CI, 0.38-4.07], P = 0.728). As dose reduction was not less expensive (€4.622 versus €4.714, delta costs/woman €92 [95%CI, -479-325]), there was no dominant strategy in the economic analysis. LIMITATIONS, REASONS FOR CAUTION: Despite our training programme, the AFC might have suffered from inter-observer variation. Although strict cancellation criteria were provided, selective cancelling in the reduced dose group (for poor response in particular) cannot be excluded as observers were not blinded for the FSH dose and small dose adjustments were allowed in subsequent cycles. However, as first cycle live birth rates did not differ from the cumulative results, the open design probably did not mask a potential benefit for the reduced dosing group. As this RCT was embedded in a larger cohort study, the power in this study was unavoidably lower than it should be. Participants had a relatively low BMI from an international perspective, which may limit generalization of the findings. WIDER IMPLICATIONS OF THE FINDINGS: In women with a predicted hyper response scheduled for IVF/ICSI, a reduced FSH dose does not affect live birth rates. A lower FSH dose did reduce the incidence of mild and moderate OHSS, but had no impact on severe OHSS. Future research into ORT-based dosing in women with a predicted hyper response should compare various safety management strategies and should be powered on a clinically relevant safety outcome while assessing non-inferiority towards live birth rates.

Hysteroscopy before in-vitro fertilisation (inSIGHT): a multicentre, randomised controlled trial.

BACKGROUND: Hysteroscopy is often done in infertile women starting in-vitro fertilisation (IVF) to improve their chance of having a baby. However, no data are available from randomised controlled trials to support this practice. We aimed to assess whether routine hysteroscopy before the first IVF treatment cycle increases the rate of livebirths. METHODS: We did a pragmatic, multicentre, randomised controlled trial in seven university hospitals and 15 large general hospitals in the Netherlands. Women with a normal transvaginal ultrasound of the uterine cavity and no previous hysteroscopy who were scheduled for their first IVF treatment were randomly assigned (1:1) to either hysteroscopy with treatment of detected intracavitary abnormalities before starting IVF (hysteroscopy group) or immediate start of the IVF treatment (immediate IVF group). Randomisation was done with web-based concealed allocation and was stratified by centre with variable block sizes. Participants, doctors, and outcome assessors were not masked to the assigned group. The primary outcome was ongoing pregnancy (detection of a fetal heartbeat at >12 weeks of gestation) within 18 months of randomisation and resulting in livebirth. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01242852. FINDINGS: Between May 25, 2011, and Aug 27, 2013, we randomly assigned 750 women to receive either hysteroscopy (n=373) or immediate IVF (n=377). 209 (57%) of 369 women eligible for assessment in the hysteroscopy group and 200 (54%) of 373 in the immediate IVF group had a livebirth from a pregnancy during the trial period (relative risk 1·06, 95% CI 0·93-1·20; p=0·41). One (<1%) woman in the hysteroscopy group developed endometritis after hysteroscopy. INTERPRETATION: Routine hysteroscopy does not improve livebirth rates in infertile women with a normal transvaginal ultrasound of the uterine cavity scheduled for a first IVF treatment. Women with a normal transvaginal ultrasound should not be offered routine hysteroscopy. FUNDING: The Dutch Organisation for Health Research and Development (ZonMW).

The OPTIMIST study: optimisation of cost effectiveness through individualised FSH stimulation dosages for IVF treatment. A randomised controlled trial.

BACKGROUND: Costs of in vitro fertilisation (IVF) are high, which is partly due to the use of follicle stimulating hormone (FSH). FSH is usually administered in a standard dose. However, due to differences in ovarian reserve between women, ovarian response also differs with potential negative consequences on pregnancy rates. A Markov decision-analytic model showed that FSH dose individualisation according to ovarian reserve is likely to be cost-effective in women who are eligible for IVF. However, this has never been confirmed in a large randomised controlled trial (RCT). The aim of the present study is to assess whether an individualised FSH dose regime based on an ovarian reserve test (ORT) is more cost-effective than a standard dose regime. METHODS/DESIGN: Multicentre RCT in subfertile women indicated for a first IVF or intracytoplasmic sperm injection cycle, who are aged < 44 years, have a regular menstrual cycle and no major abnormalities at transvaginal sonography. Women with polycystic ovary syndrome, endocrine or metabolic abnormalities and women undergoing IVF with oocyte donation, will not be included. Ovarian reserve will be assessed by measuring the antral follicle count. Women with a predicted poor response or hyperresponse will be randomised for a standard versus an individualised FSH regime (150 IU/day, 225-450 IU/day and 100 IU/day, respectively). Participants will undergo a maximum of three stimulation cycles during maximally 18 months. The primary study outcome is the cumulative ongoing pregnancy rate resulting in live birth achieved within 18 months after randomisation. Secondary outcomes are parameters for ovarian response, multiple pregnancies, number of cycles needed per live birth, total IU of FSH per stimulation cycle, and costs. All data will be analysed according to the intention-to-treat principle. Cost-effectiveness analysis will be performed to assess whether the health and associated economic benefits of individualised treatment of subfertile women outweigh the additional costs of an ORT. DISCUSSION: The results of this study will be integrated into a decision model that compares cost-effectiveness of the three dose-adjustment strategies to a standard dose strategy. The study outcomes will provide scientific foundation for national and international guidelines. TRIAL REGISTRATION: NTR2657.

The inSIGHT study: costs and effects of routine hysteroscopy prior to a first IVF treatment cycle. A randomised controlled trial.

BACKGROUND: In in vitro fertilization (IVF) and intracytoplasmatic sperm injection (ICSI) treatment a large drop is present between embryo transfer and occurrence of pregnancy. The implantation rate per embryo transferred is only 30%. Studies have shown that minor intrauterine abnormalities can be found in 11-45% of infertile women with a normal transvaginal sonography or hysterosalpingography. Two randomised controlled trials have indicated that detection and treatment of these abnormalities by office hysteroscopy after two failed IVF cycles leads to a 9-13% increase in pregnancy rate. Therefore, screening of all infertile women for intracavitary pathology prior to the start of IVF/ICSI is increasingly advocated. In absence of a scientific basis for such a policy, this study will assess the effects and costs of screening for and treatment of unsuspected intrauterine abnormalities by routine office hysteroscopy, with or without saline infusion sonography (SIS), prior to a first IVF/ICSI cycle. METHODS/DESIGN: Multicenter randomised controlled trial in asymptomatic subfertile women, indicated for a first IVF/ICSI treatment cycle, with normal findings at transvaginal sonography. Women with recurrent miscarriages, prior hysteroscopy treatment and intermenstrual blood loss will not be included. Participants will be randomised for a routine fertility work-up with additional (SIS and) hysteroscopy with on-the-spot-treatment of predefined intrauterine abnormalities versus the regular fertility work-up without additional diagnostic tests. The primary study outcome is the cumulative ongoing pregnancy rate resulting in live birth achieved within 18 months of IVF/ICSI treatment after randomisation. Secondary study outcome parameters are the cumulative implantation rate; cumulative miscarriage rate; patient preference and patient tolerance of a SIS and hysteroscopy procedure. All data will be analysed according to the intention-to-treat principle, using univariate and multivariate logistic regression and cox regression. Cost-effectiveness analysis will be performed to evaluate the costs of the additional tests as routine procedure. In total 700 patients will be included in this study. DISCUSSION: The results of this study will help to clarify the significance of hysteroscopy prior to IVF treatment. TRIAL REGISTRATION: NCT01242852.

Evaluation of anti-Müllerian hormone as a test for the prediction of ovarian reserve.

OBJECTIVE: To compare in an integral way the value of the basal serum anti-Müllerian hormone (AMH) level with most of the established ovarian reserve tests. DESIGN: Prospective randomized controlled trial. SETTING: Fertility center of a university hospital in the Netherlands. PATIENT(S): One hundred ten patients undergoing their first IVF cycle who were randomized, by a computer-designed four-block system, into two groups. INTERVENTION(S): Fifty-six patients underwent a clomiphene citrate challenge test (CCCT), and 54 patients underwent an exogenous FSH ovarian reserve test (EFORT). In all patients, basal AMH, basal FSH, basal inhibin B, antral follicle count (AFC), and basal volume of the ovaries were measured. In all patients, the test was followed by a standard IVF treatment. MAIN OUTCOME MEASURE(S): Ovarian response after ovarian hyperstimulation in an IVF treatment, expressed as the total number of stimulated follicles, retrieved oocytes, and ongoing pregnancies. RESULT(S): The best prediction of ovarian reserve (Y) was seen in a multiple regression prediction model that simultaneously included AFC, inhibin B increment in the EFORT, and basal volume of the ovaries. Univariate logistic regression showed that the best predictors for poor response were AMH, the CCCT, basal FSH, and the AFC. For hyperresponse, univariate logistic regression showed that the best predictor was AFC. Multiple logistic regression analysis did not produce a better model in terms of improving the prediction of poor response or hyperresponse. The best predictors for the prediction of non-pregnancy were the CCCT and the E(2) increment in the EFORT. CONCLUSION(S): Anti-Müllerian hormone is comparable with other commonly used ovarian reserve tests but is probably most applicable in general practice.

Ovarian volume and antral follicle count for the prediction of low and hyper responders with in vitro fertilization.

BACKGROUND: The current study was designed to compare antral follicle count (AFC) and basal ovarian volume (BOV), the exogenous FSH ovarian reserve test (EFORT) and the clomiphene citrate challenge test (CCCT), with respect to their ability to predict poor and hyper responders. METHODS: One hundred and ten regularly menstruating patients, aged 18-39 years, participated in this prospective study, randomized, by a computer designed 4-blocks system study into two groups. Fifty six patients underwent a CCCT, and 54 patients underwent an EFORT. All patients underwent a transvaginal sonography to measure the basal ovarian volume and count of basal antral follicle. In all patients, the test was followed by a standard IVF treatment. The result of ovarian hyperstimulation during IVF treatment, expressed by the total number of follicles, was used as gold standard. RESULTS: The best prediction of ovarian reserve (Y) was seen in a multiple regression prediction model that included, AFC, Inhibin B-increment in the EFORT and BOV simultaneously (Y = -3.161 + 0.805 x AFC (0.258-1.352) + 0.034 x Inh. B-incr. (0.007-0.601) + 0.511 BOV (0.480-0.974) (r = 0.848, p < 0.001). Univariate logistic regression showed that the best predictors for poor response were the CCCT (ROC-AUC = 0.87), the bFSH (ROC-AUC = 0.83) and the AFC (ROC-AUC = 0.83). Multiple logistic regression analysis did not produce a better model in terms of improving the prediction of poor response. For hyper response, univariate logistic regression showed that the best predictors were AFC (ROC-AUC = 0.92) and the inhibin B-increment in the EFORT (ROC-AUC = 0.92), but AFC had better test characteristics, namely a sensitivity of 82% and a specificity 89%. Multiple logistic regression analysis did not produce a better model in terms of predicting hyper response. CONCLUSION: In conclusion AFC performs well as a test for ovarian response being superior or at least similar to complex expensive and time consuming endocrine tests. It is therefore likely to be the test for general practise.

Ultrasonography as a tool for the prediction of outcome in IVF patients: a comparative meta-analysis of ovarian volume and antral follicle count.

OBJECTIVE: To investigate by meta-analysis the predictive capacity of ovarian volume as an ovarian reserve test in comparison to the antral follicle count (AFC). DESIGN: Meta-analysis. SETTING: Tertiary fertility center. PATIENT(S): Patients undergoing IVF. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Poor ovarian response, nonpregnancy. RESULT(S): A total of 10 studies were detected reporting on ovarian volume and 17 studies on AFC. Because of heterogeneity among studies, calculation of one summary point estimate for sensitivity and specificity was not meaningful. However, for both tests, summary receiver operating characteristic curves for the outcome measures poor response and nonpregnancy could be estimated and compared. The AFC performed statistically significantly better than ovarian volume in the prediction of poor response. The overall accuracy for predicting nonpregnancy was poor for both tests. The clinical value in poor response prediction was only evident for the AFC as a considerable number of cases can be identified who will have a high chance of producing a poor response to stimulation. The clinical value for nonpregnancy was virtually absent for both tests. CONCLUSION(S): In conclusion, the predictive performance of ovarian volume toward poor response is clearly inferior compared with that of AFC. Therefore, the AFC may be considered the test of first choice when estimating quantitative ovarian reserve before IVF. For the prediction of cases with a very low chance for pregnancy, ovarian reserve testing with the use of ultrasound appears inadequate.

The clomiphene citrate challenge test versus the exogenous follicle-stimulating hormone ovarian reserve test as a single test for identification of low responders and hyperresponders to in vitro fertilization.

OBJECTIVE: This study was designed to compare the exogenous FSH ovarian reserve test (EFORT) versus the clomiphene citrate challenge test (CCCT), basal FSH, and basal inhibin B, with respect to their ability to predict poor and/or hyperresponders in an IVF population. DESIGN: Prospective randomized controlled trial. SETTING: Fertility center of a university hospital. PATIENT(S): One hundred ten patients undergoing their first IVF cycle, randomized into two groups. INTERVENTION(S): Fifty-six patients underwent a CCCT, and 54 patients underwent an EFORT. In all patients, the test was followed by an IVF treatment. MAIN OUTCOME MEASURE(S): Ovarian response, expressed by the total number of retrieved oocytes. RESULT(S): Univariate logistic regression showed that the best predictor for poor response is the CCCT (area under receiver operator characteristic curve [ROC-AUC] = 0.87), with maximal accuracy of 0.89. Multiple logistic regression analysis did not produce a better model in terms of improving the prediction of poor response. For hyper response, univariate logistic regression showed that the best predictor is the inhibin B increment in the EFORT (ROC-AUC = 0.92) but with a low maximal accuracy of 0.78. Again, multiple logistic regression analysis did not produce a better model in terms of predicting hyper response. CONCLUSION(S): Our study, the first which compares the CCCT with the EFORT for the prediction of poor and hyperresponders, shows that the CCCT is superior for identification of low responders. The EFORT (inhibin B increment) is superior for prediction of hyper response at the cost of a high rate of false positives. Neither of the two tests seems adequate to act alone for identification of both poor and hyperresponders.

Aging women with polycystic ovary syndrome who achieve regular menstrual cycles have a smaller follicle cohort than those who continue to have irregular cycles.

OBJECTIVE: To examine whether follicle loss due to ovarian aging is responsible for the occurrence of regular menstrual cycles in aging women with polycystic ovary syndrome (PCOS), the size of the FSH-sensitive follicle cohort was estimated by the exogenous follicle-stimulating hormone ovarian reserve test (EFORT) and related to the follicle count as measured by ultrasound. DESIGN: Prospective study. SETTING: Reproductive endocrinology unit of an academic medical center. PATIENT(S): Twenty-seven aging women with PCOS (35.8-49.4 years): 20 with regular menstrual cycles and 7 with oligomenorrhea or amenorrhea. INTERVENTION(S): EFORT and transvaginal ultrasound. MAIN OUTCOME MEASURE(S): Baseline (cycle day 2, 3, or 4) FSH, androstenedione (A), T, E(2), and inhibin B levels, the E(2) and inhibin B increment after the EFORT, and the follicle count. RESULT(S): After correction for the body mass index (BMI), the inhibin B increment was higher in the irregular menstrual group, but the E(2) increment did not differ significantly between the two groups. Ultrasound showed a median follicle count of 8.5 (4.0-18.0) in women with regular menstrual cycles (n = 16), compared with 18.0 (8.0-35.0) in irregularly menstruating women (n = 7). The follicle count was significantly correlated to the FSH-induced E(2) increment (r = 0.656) as well as to the inhibin B increment (r = 0.654). The regularly menstruating group was significantly older, had a higher basal FSH concentration, and had lower androgens than the irregularly menstruating group. CONCLUSION(S): The smaller follicle count, the older age, the higher FSH concentration, and the lower FSH-induced inhibin B increment found in women with PCOS and a regular menstrual cycle confirm that a decrease in the size of the follicle cohort due to ovarian aging is largely responsible for the regular menstrual cycles in aging PCOS women.
