Oocyte cryopreservation versus ovarian tissue cryopreservation for adult female oncofertility patients: a cost-effectiveness study.

PURPOSE: In December 2019, the American Society for Reproductive Medicine designated ovarian tissue cryopreservation (OTC) as no longer experimental and an alternative to oocyte cryopreservation (OC) for women receiving gonadotoxic therapy. Anticipating increased use of OTC, we compare the cost-effectiveness of OC versus OTC for fertility preservation in oncofertility patients. METHODS: A cost-effectiveness model to compare OC versus OTC was built from a payer perspective. Costs and probabilities were derived from the literature. The primary outcome for effectiveness was the percentage of patients who achieved live birth. Strategies were compared using incremental cost-effectiveness ratios (ICER). All inputs were varied widely in sensitivity analyses. RESULTS: In the base case, the estimated cost for OC was $16,588 and for OTC $10,032, with 1.56% achieving live birth after OC, and 1.0% after OTC. OC was more costly but more effective than OTC, with an ICER of $1,163,954 per live birth. In sensitivity analyses, OC was less expensive than OTC if utilization was greater than 63%, cost of OC prior to chemotherapy was less than $8100, cost of laparoscopy was greater than $13,700, or standardized discounted costs were used. CONCLUSIONS: With current published prices and utilization, OC is more costly but more effective than OTC. OC becomes cost-saving with increased utilization, when cost of OC prior to chemotherapy is markedly low, cost of laparoscopy is high, or standardized discounted oncofertility pricing is assumed. We identify the critical thresholds of OC and OTC that should be met to deliver more cost-effective care for oncofertility patients.

Evaluating the unevaluated: a secondary analysis of the National Survey for Family Growth (NSFG) examining infertile women who did not access care.

PURPOSE: To characterize the demographic differences between infertile/sub-fertile women who utilized infertility services vs. those that do not. METHODS: A retrospective analysis of cross-sectional data obtained during the 2011-2013, 2013-2015, and 2015-2017 cycles of National Survey for Family Growth from interviews administered in home for randomly selected participants by a National Center of Health Statistics (NCHS) surveyor was used to analyze married, divorced, or women with long-term partners who reported difficulty having biological children (sub-fertile/infertile women). Demographic differences such as formal marital status, education, race, and religion were compared between women who presented for infertility care vs. those that did not. The primary outcome measure was presenting for infertility evaluation and subsequently utilizing infertility services. Healthcare utilization trends such as having a usual place of care and insurance status were also included as exposures of interest in the analysis. RESULTS: Of the 12,456 women included in the analysis 1770 (15.3%) had used infertility services and 1011 (8.3%) said it would be difficult for them to have a child but had not accessed infertility services. On univariate analysis, compared to women who used infertility services, untreated women had lower average household incomes (295.3 vs. 229.8% of the federal poverty line respectively). Untreated women also had lower levels of education and were more likely to be divorced or never have married. In terms of health status, unevaluated women were less likely to have a usual place for healthcare (87.3%) as compared to women presenting for fertility care (91.9%) (p = 0.004). When examining insurance status, 23.3% of unevaluated women were uninsured as compared to 8.3% of evaluated women. On multivariate analysis, infertile women without insurance were at 0.37 odds of utilizing infertility care compared to women with insurance. CONCLUSIONS: Demographic factors are associated with the utilization of infertility care. Insurance status is a significant predictor of whether or not infertile women will access treatment. Data from the three most recent NSFG surveys along with prior analyses demonstrate the need for expanded insurance coverage in order to address the socioeconomic disparities between infertile women who are accessing services vs. those that are not.

Negative Sliding Sign during Dynamic Ultrasonography Predicts Low Endometriosis Fertility Index at Laparoscopy.

STUDY OBJECTIVE: Endometriosis fertility index (EFI) is a robust tool to predict the pregnancy rate in patients with endometriosis who are attempting non-in vitro fertilization conception. However, EFI calculation requires laparoscopy. Newly established imaging techniques such as sliding sign, which is used to diagnose pouch of Douglas obliteration, could provide a promising alternative. The objective of this study was to investigate the practicality of using ultrasound data to predict a low EFI (score ≤6). DESIGN: Observational study from a prospective registry (Endometriosis Pelvic Pain Interdisciplinary Cohort, clinicaltrials.gov #NCT02911090). Analyzed data were captured from December 2013 to June 2017. SETTING: Tertiary referral center at British Columbia Women's Hospital. PATIENTS: We analyzed data for 2583 participants from the Endometriosis Pelvic Pain Interdisciplinary Cohort. In this cross-sectional study, we included 86 women aged <40 years. INTERVENTIONS: Dynamic ultrasonography for the sliding sign testing and EFI calculation during laparoscopic surgery. MEASUREMENTS AND MAIN RESULTS: Logistic regression was used to obtain receiver operating characteristic area under the curve (AUC) for the prediction models. Significance was p <.05. Patients with a negative sliding sign were older and had severe endometriosis and longer duration of infertility. Patients with a negative sliding sign had significantly lower total EFI scores and lower surgical factors scores than patients with a positive sliding sign. Logistic regression showed that a negative sliding sign and EFI historic factors score can predict an EFI score ≤6 (sensitivity = 87.9%, specificity = 81.1%, AUC = 0.93 [95% confidence interval, 0.88-0.98]). Adding the diagnosis of endometrioma to the previous prediction model resulted in AUC = 0.95 (95% confidence interval, 0.90-0.995), sensitivity = 84.8%, and specificity = 92.5%. CONCLUSION: The sliding sign could be a potential alternative to the EFI surgical factors, and it could be used in combination with EFI historic factors and the diagnosis of endometrioma to predict an EFI score ≤6 for patients who are not scheduled for immediate surgery.

Female adolescents and young women previously treated for pediatric malignancies: assessment of ovarian reserve and gonadotoxicity risk stratification for early identification of patients at increased infertility risk.

OBJECTIVES: Childhood and adolescent cancer survivors (CACSs) are at risk of adverse reproductive outcomes. Assessment of follicle-stimulating hormone (FSH) levels is the most common test used to diagnose premature ovarian insufficiency (POI) whereas anti-m|llerian hormone (AMH) and antral follicle count (AFC) have been proposed as ovarian reserve markers. We assessed the correlation between these markers and treatment gonadotoxicity risk (GR) in CACSs. METHODS: A total of 55 female CACSs were enrolled. GR was graded as low, medium, or high according to classifications based on disease and treatments and on cyclophosphamide equivalent dose score. FSH, AMH, and AFC were determined. POI was defined by amenorrhea and FSH>30 IU/L. For remaining patients, diminished ovarian reserve (DOR) was defined by AMH<5th centile. FSH and AFC cut-offs proposed in the literature as DOR markers were also considered (FSH>10 IU/L or >95th centile; AFC<8 or <5th centile). RESULTS: Ovarian reserve results to be compromised in 23 (41.8%) patients: 14 with DOR and 9 with an established POI. Results showed GR classifications to be a good predictor of ovarian reserve, with significantly lower AMH and AFC in the high-risk groups. AFC resulted to be directly correlated with AMH (r=0.75, p<0.001). CONCLUSIONS: In CACSs, GR classifications correlate with post-treatment AMH and AFC. These are useful tools in the early identification of young patients with DOR, who may benefit from reproductive and fertility preservation counseling. Further studies are needed to determine the rate and time of progression from DOR to POI in this population.

A novel mathematical model of true ovarian reserve assessment based on predicted probability of poor ovarian response: a retrospective cohort study.

PURPOSE: To establish a mathematical model for assessing the true ovarian reserve based on the predicted probability of poor ovarian response (POR). METHODS: In this retrospective cohort study, a total of 1523 GnRH-antagonist cycles in 2017 were firstly analyzed. The ovarian responses were calculated based on the number of retrieved oocytes. The continuous variables were converted into categorical variables according to cutoff values generated by the decision tree method. The optimal model was identified using forward stepwise multiple logistic regression with 5-fold cross-validation and further verified its performances using outer validation data. RESULTS: The predictors in our model were anti-Müllerian hormone (AMH), antral follicle counts (AFC), basal follicle-stimulating hormone (FSH), and age, in order of their significance, named AAFA model. The AUC, sensitivity, specificity, positive predictive value, and negative predictive value of AAFA model in inner validation and outer validation data were 0.861 and 0.850, 0.603 and 0.519, 0.917 and 0.930, 0.655 and 0.570, and 0.899 and 0.915. Ovarian reserve of 16 subgroups was further ranked according to the predicted probability of POR and further divided into 4 groups of A-D using clustering analysis. The incidence of POR in the four groups was 0.038 (0.030-0.046), 0.139 (0.101-0.177), 0.362 (0.308-0.415), and 0.571 (0.525-0.616), respectively. The order of ovarian reserve from adequate to poor followed the order of A to D. CONCLUSION: We have established an easy applicable AAFA model for assessing true ovarian reserve and may have important implications in both infertile women and general reproductive women in Chinese or Asian population.

Detailed endometrial immune assessment of both normal and adverse reproductive outcome populations.

PURPOSE: Using a comprehensive flow cytometric panel, do endometrial immune profiles in adverse reproductive outcomes such as repeat implantation failure (RIF) and repeat pregnancy loss (RPL) differ from each other and male-factor controls? METHODS: Six-hundred and twelve patients had an endometrial biopsy to assess the immunophenotype. History on presentation was used to subdivide the population into recurrent implantation failure (RIF) [n = 178], recurrent pregnancy loss (RPL) [n = 155], primary infertility [n = 130] and secondary infertility [n = 114]. A control group was utilised for comparative purposes [n = 35] and lymphocyte subpopulations were described. RESULTS: Distinct lymphocyte percentage differences were noted across the populations. Relative to controls and RPL, patients with a history of RIF had significantly raised uterine NKs (53.2 vs 45.2 & 42.9%, p < 0.0001). All sub-fertile populations had increased percentage peripheral type NKs (p = 0.001), and exhibited increased CD69+ activation (p = 0.005), higher levels of B cells (p < 0.001), elevated CD4:CD8 ratio (p < 0.0001), lower T-regs (p = 0.034) and a higher proportion of Th1+ CD4s (p = 0.001). Patient aetiology confers some distinct findings, RPL; pNK, Bcells and CD4 elevated; RIF; uNK and CD56 raised while CD-8 and NK-T lowered. CONCLUSIONS: Flow cytometric endometrial evaluation has the ability to provide a rapid and objective analysis of lymphocyte subpopulations. The findings show significant variations in cellular proportions of immune cells across the patient categories relative to control tissue. The cell types involved suggest that a potential differential pro-inflammatory bias may exist in patients with a history of adverse reproductive outcomes. Immunological assessment in appropriate populations may provide insight into the underlying aetiology of some cases of reproductive failure.

Multiplex PCR from Menstrual Blood: A Non-Invasive Cost-Effective Approach to Reduce Diagnostic Dilemma for Genital Tuberculosis.

AIM: Genital tuberculosis (GTB) is a potent contributor to irreversible damage to the reproductive system and infertility in females. As no gold standard diagnostic tool is yet available, clinical suspicion and relatively insensitive approaches such as histopathology, laparoscopy and hysterosalpingogram are currently critical determinants in the diagnosis of GTB. Although a polymerase chain reaction (PCR)-based assay using endometrial tissue seems promising, sampling does require an invasive procedure. OBJECTIVE: We hypothesized that menstrual blood may provide an alternate non-invasive source of samples for PCR-based GTB diagnosis. METHODS: We enrolled 195 women with primary infertility in whom GTB was suspected. We obtained ethics committee approval from our institution and written informed consent from subjects. Endometrial tissue and menstrual blood was collected from the subjects and culture, histopathology, and multiplex PCR with both sample type was performed for each subject. RESULTS: The sensitivity and specificity of multiplex PCR was, respectively, 90.2 and 86.1% for menstrual blood, 95.8 and 84.3% for endometrial tissue, and 64.8 and 93.2% for histopathology staining. CONCLUSIONS: A strong clinical suspicion aided with multiplex PCR using menstrual blood may significantly reduce the diagnostic dilemma for GTB diagnosis in a non-invasive, sensitive, rapid, and cost-effective manner.

Baseline anatomical assessment of the uterus and ovaries in infertile women: a systematic review of the evidence on which assessment methods are the safest and most effective in terms of improving fertility outcomes.

BACKGROUND: This review focuses on the initial presentation of women who suspect that they are infertile, and how best to assess the anatomy of their uterus and ovaries in order to investigate the cause of their infertility, and potentially improve desired fertility outcomes. This review was undertaken as part of a World Health Organization initiative to assess the evidence available to address guidance for the diagnosis and treatment of infertility within a global context. Providing access to care for infertile women will help to ease the psycho-social burdens, such as ostracization, intimate partner violence and other negative consequences of being involuntarily childless or unable to become pregnant despite desiring a biological child or children. OBJECTIVE AND RATIONALE: The aim of this paper was to present an evidence base for the diagnostic and prognostic value of various investigations used for detecting uterine and/or ovarian pathology in women presenting at fertility clinics for their initial assessment. SEARCH METHODS: We performed a comprehensive search of relevant studies on 28 August and 10 September 2014. A further search was performed on 6 June 2016 to ensure all possible studies were captured. These strategies were not limited by date or language. The search returned 3968 publications in total; 63 full text articles were retrieved and 10 additional studies were found through hand-searching. After excluding 54, a total of 19 studies were analysed. We extracted and tabulated data on the characteristics, quality and results of each eligible study and combined the findings in a narrative synthesis. Risk of bias was assessed according to article type using tools such as assessment of the methodological quality of systematic reviews, Newcastle Ottawa Scale, Cochrane risk of bias tool, quality assessment tool for diagnostic accuracy studies and quality in prognostic studies. Nineteen studies were selected as being the best evidence available. A narrative synthesis of the data was undertaken. Discussion of the data, and resultant consensus for best practice were accomplished in a consensus expert consultation in Geneva, October 2015. An independent expert review process concerning this work and outcomes was conducted during 2016. OUTCOMES: The draft recommendations presented here apply to infertile women whether or not they are undergoing fertility treatment. Transvaginal ultrasound (TVUS) should be offered to all infertile women with symptoms or signs of anatomic pelvic pathology. TVUS should not be offered routinely to women without symptoms of pelvic pathology. Hysteroscopy should be offered if intrauterine pathology is suspected by TVUS. Hysteroscopy should not be routinely offered to infertile women who have normal TVUS findings. In women who have normal TVUS findings and are undergoing IVF, hysteroscopy does not improve the outcome. Good practice points recommend that providers of fertility care should confirm that all infertile women have a recent pelvic examination, recent cervical screening and well-woman screening in line with local guidelines. Additionally, hystero-contrast salpingography in infertile women does not improve clinical pregnancy rates with expectant management in heterosexual couples and should not be offered as a therapeutic procedure. Most of the findings of this review on diagnosis are based on a low, or very low, quality of evidence, according to GRADE Working Group (grading of recommendations, assessment, development and evaluation) criteria. A low quality grading indicates that further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate, while a very low grade indicates that any estimate of effect is very uncertain. WIDER IMPLICATIONS: This review provides the most reliable evidence available to guide clinicians worldwide in the initial, evidence-based investigation of women with fertility problems in order to undertake the most useful investigation and avoid the burden of unnecessary tests.

Implantation failure of endometrial origin: it is not pathology, but our failure to synchronize the developing embryo with a receptive endometrium.

Repeated implantation failure (RIF) is an intriguing, massive failure of reproductive treatment in otherwise healthy women leading to the introduction of empirical adjuvant interventions that are costly, inefficient, and frustrating for our patients. In this article, we will try to convince the readers that RIF is neither a stigma nor a mysterious pathology but rather our failure to diagnose and properly synchronize the euploid blastocyst with the patient's personalized window of implantation.

Contribution of Hormonal Cytology in Girls and Adolescents to Reproductive Health: A Traditional Technique Monitoring Recent Problems.

OBJECTIVE: To study the contribution of hormonal cytology in contemporary disturbances of fertility. DESIGN: Over a 10-year period (2006-2015), 6,688 vaginal fornix cytologies of 2,350 patients were investigated. For a more detailed analysis, a 3-year period from 2013 to 2015 was chosen. Four hundred and fifty-two patients were investigated, many of them several times and for a period longer than the 3 years analyzed. RESULTS: The main disorders examined and treated via a gentle hormonal medication support and life style corrections by a pediatric gynecologist were: pubertas praecox - thelarche praecox and early menarche; dysfunctional juvenile metrorrhagia; central and peripheral endocrine disorders; eating disorders - anorexia mentalis and bulimia; obesity; excessive sport activities; autoimmune disorders, and others. Normalization of the menstrual cycle was achieved while monitoring progress with a series of hormonal cytologies in a majority of patients. CONCLUSIONS: Hormonal cytology is a non-invasive and economical method, illustrating the direct effect of steroid on target cells. It contributes to reproductive health support by: (a) indicating the possible need and type of steroid therapy; (b) monitoring the normalization of cycle disturbances; (c) ruling out or indicating the need for more detailed steroid metabolism investigation. Thus, it represents a basic but valuable means of examination in child and adolescent gynecology.

Multi-modal magnetic resonance elastography for noninvasive assessment of ovarian tissue rigidity in vivo.

For centuries, physicians have relied on touch to palpate tissue and detect abnormalities throughout the body. While this time-tested method has provided a simple diagnostic examination for large, superficial abnormalities, it does not permit quantifiable measurements of stiffness in deeper, small organs. Advances in noninvasive imaging to measure tissue rigidity represent important extensions of manual palpation techniques. Tissue fibrosis occurs with age in many organs; in the ovary, it is thought to be a marker of polycystic ovary syndrome and age-related idiopathic infertility, although quantitative assessment of fibrosis in this deep, abdominal tissue has not been possible. We used noninvasive methods to quantify ovarian tissue rigidity and clarify the role of tissue stiffness in reproductive health. With proper validation against accepted standards, noninvasive imaging techniques may become the quantitative counterpart to interior probing palpation methods and invasive (surgical) diagnoses, with applications across many clinical settings, including evaluation of adolescent and young adult ovarian function.

[Comparison of fertiloscopy versus laparoscopy in the exploration of the infertility: analysis of the literature]. / Comparaison de la fertiloscopie à la cœlioscopie dans l'exploration de l'infertilité: analyse de la littérature.

BACKGROUND: Fertiloscopy is a recent technique designed to explore the tubo-ovarian axis in unexplained infertility. It is a simple outpatient technique, allowing to perform operative procedures, but its position relative to laparoscopy is yet to be defined. MATERIAL AND METHODS: A thorough and extensive bibliographical search was undertaken to fully embrace the question, challenging Medline at the National Library of Medicine, Cochrane Library, National Guideline Clearinghouse, Health Technology Assessment Database. All the retrieved articles were classified as either descriptive or comparative studies and evaluated on a set of criteria. RESULTS: Most of the papers described case series coming from a few teams, focusing mainly on the technical aspect of the procedure, like the access rate to the posterior cul-de-sac, the success rate in visualizing the pelvis, the complications rate (mainly rectal perforation), and its operative performance in drilling ovaries for resistant polycystic ovarian syndrome. Comparative studies numbered six trials. They all followed the same design, fertiloscopy preceding conventional laparoscopy in patients taken as their own control. The concordance rate between the two modalities reaches 80% in terms of tubal pathology, adherences and endometriosis, with an estimated reduction of laparoscopies varying from 40% to 93%. CONCLUSION: The current literature shows a concordance between fertiloscopy and conventional laparoscopic findings for certain parameters in cases of tubal pathology, adherences and endometriosis. The relative positions of these two modalities in unexplained infertility still remain elusive.

Office diagnostic and operative hysteroscopy using local anesthesia only: an analysis of patient reported pain and other procedural outcomes.

STUDY OBJECTIVE: To evaluate the effectiveness of a multimodality local anesthetic protocol for office diagnostic and operative hysteroscopy. DESIGN: Retrospective cohort study (Canadian Task Force classification II-3). SETTING: Academic community-based institution. PATIENTS: Five hundred sixty-nine women undergoing 639 office-based diagnostic or operative hysteroscopic procedures. INTERVENTIONS: Multimodality local anesthetic protocol addressing vagina, cervix, paracervical region, and endometrial cavity. MEASUREMENTS AND MAIN RESULTS: Primary outcomes were numeric pain scores and rate of premature termination because of pain. Secondary outcomes included procedure pain and parity, delivery route, menopausal status, procedure type, and cost effect on procedure delivery. The overall mean (SD) pain score across 535 evaluable procedures was 3.7 (2.5). Patients undergoing operative hysteroscopy had a higher mean maximum pain score than did those who underwent diagnostic hysteroscopy only (4.1 vs 3.2; p < .001). There was no difference among women in different age groups; however, those with both cesarean section and vaginal delivery had scores higher than the mean (4.7 [0.4]; p < .001). The estimated cost savings was almost $2 million. CONCLUSION: Using a multimodality approach to local anesthesia, a broad spectrum of diagnostic and operative procedures can be performed successfully, comfortably, and inexpensively in the context of an office procedure room, without the need for procedural sedation.

Follicular fluid from infertile women with mild endometriosis may compromise the meiotic spindles of bovine metaphase II oocytes.

STUDY QUESTION: What is the potential impact of follicular fluid (FF) from infertile women with mild endometriosis (ME) on oocyte quality, especially on nuclear maturation and the meiotic spindle? SUMMARY ANSWER: FF from infertile women with ME may compromise nuclear maturation and the meiotic spindles of in vitro matured bovine oocytes. WHAT IS KNOWN ALREADY: Controversial studies have suggested that impaired oocyte quality may be involved in the pathogenesis of endometriosis-related infertility. Moreover, some studies have demonstrated alterations in the composition of FF from infertile women with endometriosis. However, to date no study has evaluated the effect of FF from infertile women with ME on the genesis of meiotic oocyte anomalies. STUDY DESIGN, SIZE, DURATION: We performed an experimental study. Samples of FF were obtained from February 2009 to February 2011 from 22 infertile women, 11 with ME and 11 with tubal or male factors of infertility (control group), who underwent ovarian stimulation for ICSI at our university IVF Unit. From March 2011 to February 2012 we performed in vitro maturation (IVM) experiments using immature bovine oocytes as described below. PARTICIPANTS/MATERIALS, SETTING, METHODS: FF free of blood and containing a mature oocyte was obtained from 22 infertile women during oocyte retrieval for ICSI. Immature bovine oocytes underwent IVM in the absence of FF (No-FF) and in the presence of four concentrations (1, 5, 10 and 15%) of FF from infertile women without endometriosis (C-FF) and with ME (ME-FF). Eleven replicates were performed, each one using FF from a control patient and a patient with ME. Each FF sample was used in only one experiment. After 22-24 h of IVM, oocytes were denuded, fixed and immunostained for morphological visualization of microtubules and chromatin by confocal microscopy. MAIN RESULTS AND THE ROLE OF CHANCE: A total of 1324 cumulus-oocyte complexes were matured in vitro. Of these, 1128 were fixed and 1048 were analyzed by confocal microscopy. The percentage of meiotically normal oocytes was significantly higher for oocytes that underwent IVM in the absence of FF (No-FF; 76.5%) and in the presence of 1% (80.9%), 5% (76.6%), 10% (75%) and 15% (76.2%) C-FF than in oocytes that underwent IVM in the presence of 1% (44.4%), 5% (36.7%), 10% (45.5%) and 15% (51.2%) ME-FF (P < 0.01). No differences were observed among FF concentrations within each group. When the four concentrations from each group were pooled, the number of oocytes in metaphase I stage was significantly higher in the ME-FF (50 oocytes) than in the C-FF (29 oocytes) group and the percentage of meiotic abnormalities was significantly higher when oocytes were matured with ME-FF (55.8%) than with C-FF (23.1%), P < 0.01. LIMITATIONS, REASONS FOR CAUTION: Owing to the strict selection criteria for FF donors, this study had a small sample size (11 cases and 11 controls), and thus further investigations using a large cohort of patients are needed to confirm these results. In addition, data obtained from studies using animal models may not necessarily be extrapolated to humans and studies evaluating in vivo matured oocytes from infertile women with ME are important to confirm our results. WIDER IMPLICATIONS OF THE FINDINGS: Our results open new insights into the pathogenic mechanisms of infertility related to mild endometriosis, suggesting that FF from infertile women with mild endometriosis may be involved in the worsening of oocyte quality of these women. STUDY FUNDING/COMPETING INTEREST(S): This study was supported by the National Council for Scientific and Technological Development (CNPq), Brazil. The authors declare no conflicts of interest.

Comparison of HSCORE assessment of endometrial beta3 integrin subunit expression with digital HSCORE using computerized image analysis (ImageJ).

OBJECTIVE: To compare intraobserver and interobserver variation between traditional histological score (HSCORE) and digital HSCORE (D-HSCORE) performed by expert and naive researchers. STUDY DESIGN: Immunohistochemical analysis of beta3 integrin subunit of 100 endometrial biopsies obtained from the midluteal phase of the menstrual cycle were reanalyzed using ImageJ software (D-HSCORE). Mean intensity of 3,3'-diaminobenzidine on endometrial glands was read by an expert (HSCORE) versus inexperienced observer using HSCORE and D-HSCORE. RESULTS: The mean correlation [r(s)(95% CI)] between both methods was 0.86 (0.79-0.90) and highly significant (p < 0.0001) for the experienced individual. The naive researcher overestimated immunostaining, resulting (HSCORE) in negative samples. No discrepancies were seen with D-HSCORE. Interobserver variation for the inexperienced reader was 50% using HSCORE (cutoff 0.7) but 0% with D-HSCORE. Intraobserver variation using ImageJ was 0%. CONCLUSION: The D-HSCORE performed by an inexperienced researcher has high correlation to traditional HSCORE performed by an expert.

Optimising vitrification of human oocytes using multiple cryoprotectants and morphological and functional assessment.

Oocyte vitrification is a clinical practice that allows preservation of fertility potential in women. Vitrification involves quick cooling using high concentrations of cryoprotectants to minimise freezing injuries. However, high concentrations of cryoprotectants have detrimental effects on oocyte quality and eventually the offspring. In addition, current assessment of oocyte quality after vitrification is commonly based only on the morphological appearance of the oocyte, raising concerns regarding its efficiency. Using both morphological and functional assessments, the present study investigated whether combinations of cryoprotectants at lower individual concentrations result in better cryosurvival rates than single cryoprotectants at higher concentrations. Surplus oocytes from IVF patients were vitrified within 24h after retrieval using the Cryotop method with several cryoprotectants, either individually or in combination. The morphological and functional quality of the vitrified oocytes was investigated using light microscopy and computer-based quantification of mitochondrial integrity, respectively. Oocyte quality was significantly higher using a combination of cryoprotectants than vitrification with individual cryoprotectants. In addition, the quality of vitrified oocyte varied depending on the cryoprotectants and type of combination used. The results of the present study indicate that observations based purely on the morphological appearance of the oocyte to assess the cryosurvival rate are insufficient and sometimes misleading. The outcome will have a significant implication in the area of human oocyte cryopreservation as an important approach for fertility preservation.

Assessment of theca cell function: a prerequisite to androgen or luteinizing hormone supplementation in poor responders.

Poor responders are a heterogeneous population, with some patients displaying a diminished ovarian reserve and others a poor ovarian reserve with preserved granulosa cell function. Androgen and LH/hCG supplementation has been advocated for poor responders, mainly those >40 years old. Although androgens synergistically act with FSH to support folliculogenesis, and ovarian androgen secretion declines with age, there is still no evidence that androgen therapy is actually effective to improve ovarian FSH sensitivity. The main reason seems to be that theca cell function has not been appropriately assessed in patients at risk of poor response. The definition of theca insufficiency is hampered by methodologic shortcomings in routine bioassays. Provocative tests for theca cells might help to identify those patients who could benefit from androgen supplementation. The lack of data regarding theca cells in these patients might contribute to explaining the absence of evidence for a positive effect of androgen therapy.

Value of three-dimensional hysterosalpingo-contrast sonography with SonoVue in the assessment of tubal patency.

OBJECTIVE: To investigate the accuracy of transvaginal three-dimensional hysterosalpingo-contrast sonography using SonoVue (3D SonoVue-HyCoSy) in the assessment of Fallopian tubal patency. METHODS: We recruited 75 infertile patients undergoing 3D SonoVue-HyCoSy before standard diagnostic laparoscopy with chromotubation (lap and dye). Tubal patency was assessed by automated 3D coded contrast imaging (3D SonoVue-HyCoSy), and the findings were compared with the results of lap and dye. RESULTS: For detecting tubal patency among the 150 Fallopian tubes assessed, 3D SonoVue-HyCoSy had a sensitivity of 93.5%, specificity of 86.3%, positive and negative predictive values of 87.8% and 92.6%, respectively, and diagnostic accuracy of 90.0%. The test-positive rates of 3D SonoVue-HyCoSy vs lap and dye were not significantly different (82/150 vs 77/150, P > 0.05). CONCLUSION: 3D SonoVue-HyCoSy should be considered clinically valuable as a practical, non-invasive, primary investigatory tool for evaluating tubal patency.

Automated assessment of ovarian follicles using a novel three-dimensional ultrasound software.

OBJECTIVE: To evaluate the accuracy, efficiency, and applicability of a new automated method of follicular assessment. DESIGN: Retrospective review of three-dimensional ultrasonographic ovarian volumes. SETTING: Academic center. PATIENT(S): Three-dimensional ovarian volumes from patients undergoing IVF. INTERVENTION(S): Three-dimensional volumes of gonadotropin-stimulated ovaries and simulated ovarian follicles (SOFs) of known volume were evaluated with the new automated follicular assessment software (SonoAVC). MAIN OUTCOME MEASURE(S): [1] Maximum absolute error for the SonoAVC in assessing the volumes of the SOFs; [2] correlations between the automated and manual follicular measurements; [3] time required to analyze all of the follicles in a given ovarian volume. RESULT(S): The SOF of 4, 6, and 10 mm were evaluated. The SonoAVC's maximum absolute error for the volumes of the 4, 6, and 10 mm SOFs was 0 (0%), 0.01 (8.3%), and 0.02 (3.8%) cc, respectively. Three hundred forty-seven follicles, ranging in diameter from 2.3-32 mm, were evaluated. The correlation coefficient for the SonoAVC-generated relaxed follicular diameter and the manual measured mean follicular diameter was 0.99. The time required to analyze all of the follicles in a given ovarian volume for the automated and manual method was 133 versus 361 seconds, respectively. CONCLUSION(S): The SonoAVC proved to be a very accurate and efficient way to measure ovarian follicles. The measurements obtained by the SonoAVC correlated extremely well with the manual measurements we obtained.

Perifollicular vascularity assessment for selecting the best oocytes for in vitro fertilization programs in older patients.

The current prospective, randomized, controlled study aimed to assess the clinical efficacy of the perifollicular vascularity assessment by using power Doppler ultrasonography, as an additive criterion to the standard morphologic ones, for choosing the most competent oocytes. Data obtained from 60 infertile patients who were >40 years of age and were unselected for ovarian reserve showed that this approach does not improve any reproductive outcomes in IVF programs.
