RESUMO

STUDY QUESTION: What is the agreement between antral follicle count (AFC) and anti-Müllerian hormone (AMH) levels when used to patient classification according to the Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number (POSEIDON) criteria? SUMMARY ANSWER: Our study indicates a strong agreement between the AFC and the AMH levels in classifying POSEIDON patients; thus, either can be used for this purpose, although one in four women will have discordant values when both biomarkers are used. WHAT IS KNOWN ALREADY: According to the POSEIDON criteria, both AFC and AMH may be used to classify low-prognosis patients. Proposed AFC and AMH thresholds of 5 and 1.2 ng/ml, respectively, have their basis in published literature; however, no study has yet determined the reproducibility of patient classification in comparing one biomarker with the other, nor have their thresholds ever been validated within this patient population. STUDY DESIGN, SIZE, DURATION: A population-based cohort study involving 9484 consecutive patients treated in three fertility clinics in Brazil, Turkey and Vietnam between 2015 and 2017. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants were infertile women between 22 and 46 years old in their first in vitro fertilization/intracytoplasmic sperm injection cycle of standard ovarian stimulation with exogenous gonadotropins whose baseline ovarian reserves had been assessed by both AFC and AMH. Details of pre- and post-treatment findings were input into a coded research file. Two indicators of interest were created to classify patients according to the POSEIDON criteria based upon AFC and AMH values. Patients who did not fit any of the four POSEIDON groups were classified as non-POSEIDON. AFC was determined in the early follicular phase using two-dimensional (2D) transvaginal ultrasonography, whereas AMH values were based on the modified Beckman Coulter generation II enzyme-linked immunosorbent assay. Agreement rates were computed between AFC and AMH to classify patients using Cohen's kappa statistics. Logistic regression analyzes were carried out to examine the association between ovarian markers and low (<4) and suboptimal (4-9) oocyte yield. MAIN RESULTS AND THE ROLE OF CHANCE: The degree of agreement in classifying patients according to POSEIDON groups was strong overall (kappa = 0.802; 95% CI: 0.792-0.811). A total of 73.8% of individuals were classified under the same group using both biomarkers. The disagreement rates were ∼26% and did not diverge when AFC or AMH was used as the primary biomarker criterion. Significant regression equations were found between ovarian markers and oocyte yield (P < 0.0001). For low oocyte yield, the optimal AFC and AMH cutoff values were 5 and 1.27 ng/ml with sensitivities of 0.61 and 0.66, specificities of 0.81 and 0.72, and AUC receiver operating characteristics of 0.791 and 0.751, respectively. For suboptimal oocyte yield respective AFC and AMH cutoffs were 12 and 2.97 ng/ml with sensitivities of 0.74 and 0.69, specificities of 0.76 and 0.66 and AUCs of 0.81 and 0.80. LIMITATIONS, REASONS FOR CAUTION: Our study relied on 2D transvaginal sonography to quantify the AFC and manual Gen II assay for AMH determination and classification of patients. AMH data must be interpreted in an assay-specific manner. Treatment protocols varied across centers potentially affecting patient classification. WIDER IMPLICATIONS OF THE FINDINGS: Three of four patients will be classified the same using either AFC or AMH values. Both biomarkers provide acceptable and equivalent accuracy in predicting oocyte yield further supporting their use and proposed thresholds in daily clinical practice for patient classification according to the POSEIDON criteria. However, the sensitivity of POSEIDON thresholds in predicting low oocyte yield is low. Clinicians should adopt the biomarker that may best reflect their clinical setting.

RESUMO

OBJECTIVE: To identify the effects of interactive music therapy on stress levels in women undergoing high complexity infertility treatments. METHODS: Prospective randomized study involving 113 women treated in the Reproduction Human Laboratory of the Clinics Hospital of the Federal University of Goiás State, submitted to in vitro fertilization/intracytoplasmic sperm injection. We used Depression, Anxiety and Stress Scale, and Lipp's Stress Symptoms Inventory for Adults. In the Intervention Group, we used small and easy to play percussive musical instruments, a guitar, voice, and a recorder. We used interactive music therapy approach individually, applied before baseline ultrasound scan, oocyte pick-up, and embryo transfer. We analyzed the data using the R. Paired Student t-test to compare the results. RESULTS: Comparison of the stress levels by Depression, Anxiety and Stress Scale between the groups in the final moment of data retrieval resulted in 23.13 (SD±10.51; n=32) in the Control Group and 16.12 (SD±7.87; n=33) in the Intervention Group, being statistically different (p=0.004). Also in Lipp's Stress Symptoms Inventory for Adults there was a significant stress reduction in 39% of the patients in the Intervention Group compared to a reduction of 14% in the patients of the Control Group (p=0.032). In this same measurement resulted that only 3% of the Intervention Group patients versus 23% of the Control Group patients (p=0.027) were in the exhaustion stage. CONCLUSION: Interactive music therapy was effective for stress reduction in women during assisted reproduction techniques.

RESUMO

OBJECTIVE: To investigate if high anti-Müllerian hormone (AMH) concentration is a useful tool to predict the outcome of assisted reproductive treatment. METHODS: Retrospective cohort study involving 520 patients who underwent IVF/ICSI procedures in a university hospital. We measured the serum AMH level on day 3 of the menstrual cycle. Based on AMH levels, we divided the patients into three groups as follows: low (<25th percentile) AMH group, average (25th to 75th percentile) AMH group and high (>75th percentile) AMH group. We recorded the fertilization rate (FR), the number of oocytes retrieved, the number of good quality embryos (GQEs) and the clinical pregnancy rate (CPR). RESULTS: There was no difference between the three AMH groups in terms of maternal age, body mass index (BMI), follicle-stimulating hormone (FSH), estradiol (E2), luteinizing hormone (LH) and testosterone (T) in the IVF/ICSI cycles. The women in the high serum AMH group had a higher number of retrieved oocytes than those in the low or average AMH groups (p < 0.01) in the IVF/ICSI cycles. Compared with the low or average AMH groups, the women with high AMH levels had a higher number of good quality embryos (GQEs) in the IVF/ICSI cycles (p < 0.01). However, high AMH women had no significantly higher clinical pregnancy rate (CPR) compared to the women in the low or average AMH groups. In addition, for the prediction of CPR, the AMH levels alone were not an independent predictor of CPR for IVF and ICSI cycles in the ROC curve analysis. CONCLUSIONS: High anti-Müllerian hormone levels are an independent predictor of the number of retrieved oocytes and good quality embryos (GQEs), but might not reflect the likelihood of higher clinical pregnancy rates (CPR) in IVF/ICSI treatment.

RESUMO

Poor ovarian response remains one of the most challenging tasks for an IVF clinician. In this review, we aim to highlight the ongoing research for optimizing the prognosis in poor ovarian response patients. The newly introduced POSEIDON criteria argue that the first step is to move from a poor response to a poor prognosis concept, while improving identification and stratification of the different sub-types of poor prognosis patients prior to ovarian stimulation. The immediate marker of success is the ability of the ovarian stimulation to retrieve the number of oocytes needed to obtain at least one euploid blastocyst for transfer in each patient. This surrogate marker of success should not replace live birth as the most important outcome, but it should be approached as a useful tool for clinicians to evaluate their strategy for achieving live birth in the shortest timespan possible in the individual patient/ couple.

RESUMO

STUDY QUESTION: What factors are associated with monozygotic twins (MZT) after autologous IVF/ICSI with fresh and frozen/thawed single embryo transfer (SET) and what is the outcome of MZT? SUMMARY ANSWER: Factors associated with increased MZT were blastocyst transfer and elective single embryo transfer (eSET), with MZT showing a lower gestational age at birth and neonatal weight but higher perinatal mortality only after fresh transfer. WHAT IS KNOWN ALREADY: ART is associated with an increased incidence of MZT, which carries higher perinatal mortality. However, risk factors associated with MZT are still controversial. STUDY DESIGN SIZE DURATION: A population-based retrospective analysis of data extracted from ART cycles reported to the Latin American Registry of ART between January 2012 and December 2016 was used in order to study the frequency and outcome of MZT after SET. PARTICIPANTS/MATERIAL SETTING METHODS: In total, 2925 clinical pregnancies obtained after autologous IVF/ICSI with fresh SET were used to study biomedical factors possibly associated with MZT, such as maternal age, type of insemination, use of assisted hatching, stage of embryo development at transfer, elective or non-elective SET and preimplantation genetic testing. Another group of 3085 clinical pregnancies obtained after SET of frozen-thawed embryo transfer (FET) was also used to study the possible association between embryo freezing and MZT. Only pregnancies with complete follow-up until birth were included in this analysis. The diagnosis of MZT was established by transvaginal ultrasound performed at 6­8 weeks of amenorrhea. The rate of MZT for each potential risk factor was obtained and a multivariable logistic regression was performed in order to account for the above-mentioned factors. Pregnancies were followed until birth and the early neonatal period in order to assess the rate of miscarriage and stillbirths, gestational age at birth, neonatal weight and early neonatal mortality. MAIN RESULTS AND ROLE OF CHANCE: There were 76 MZT out of 2925 clinical pregnancies with fresh SET (2.6%) and 69 MZT out of 3085 clinical pregnancies after FET (2.2%) (odds ratio (OR) = 0.85, 95% CI 0.61­1.19). A statistically significantly increase in MZT rate was observed with blastocyst compared with cleavage stage ET (3.4 versus 2.0%, respectively; OR = 1.70, 95% CI 1.05­2.76). When confounding variables were considered, eSET was also significantly associated with an increase in the odds of MZT (OR = 1.74, 95% CI 1.04­2.92). Overall perinatal mortality was higher in MZT compared with singletons, but this rise was only significant after fresh ET. LIMITATIONS REASONS FOR CAUTION: Limitations of the current study result from the fact that MZT were diagnosed with ultrasound performed at 6­8 weeks of amenorrhea; therefore, spontaneous embryo reductions taking place earlier were missed. WIDER IMPLICATIONS OF THE FINDINGS: Reproductive health providers must inform their patients that blastocyst transfer and eSET of fresh embryos are associated with a statistically significantly increase in the odds of MZT and that perinatal mortality after fresh ET is significantly higher in MZT than in singletons. STUDY FUNDING/COMPETING INTERESTS: The Latin American Registry of ART receives direct funding from Ferring Pharmaceuticals, but no specific funding was received to undertake this study. None of the authors declare conflict of interest.

RESUMO

OBJECTIVE: This study seeks to identify the role and possible participation of a psychologist/psychoanalyst inside an Oocyte Pick-up Room and Recovery Room (OPR-RR) in an Assisted Reproduction clinic and its implications on patients and team. METHODS: Prospective study of psychological support during the procedures from September 2014 to December 2018. Most visits took place during oocyte retrievals, for either IVF/ICSI or gamete freezing. RESULTS: Of the 2,343 cases, the psychologist was present in 965 of them (41%), during oocyte retrievals, with available professionals in 59% of the times (722 cases). The embryo transfers (1,011) had psychological assistance in 20% of the time (218 cases). The intrauterine insemination cases were excluded for not happening in a surgical environment. The recovery room was identified as one of the spaces for welcoming and listening to anxieties, desires, projects, worries, fears, frustrations, joys and expectations for those who come to the clinic seeking the desire to gestate. The patients' talks, collected in observations transcribed from what was heard, with dates and types of procedures, were discussed with either the team or the assistant physician. The team stands positively in the presence of a psychologist/psychoanalyst, who brings new perceptions and the development of the whole art of listening, for all involved. CONCLUSION: The presence of a psychologist/psychoanalyst in the Oocyte Pick-up Room and the Recovery Room in an Assisted Reproduction clinic means an opportunity to listen to patients' emotions, providing well-being to patients and echoing in the teamwork relationships.

RESUMO

IUI has been practiced for five decades but only three unconvincing trials attempted to demonstrate the superiority of IUI over sexual intercourse (SI). In the absence of evidence of its effectiveness, the National Institute for Clinical Excellence (NICE) recommended IVF over IUI after 2 years of unprotected SI. High-quality recent data in well-constructed studies suggest that biases against IUI procedures and in favour of IVF are invalid. It is unethical to continue to misinform patients and stakeholders. The well-constructed randomised controlled trials (RCT) show IUI procedure to be efficient, with minimal risk, and above all improved cost-effectiveness when compared to IVF for live birth. IUI as first-line treatment should be offered to most patients, while funding agencies and stakeholders need to be urgently informed of the cost-benefit in offering IUI. Fertility clinics, IVF interest groups, and regulatory bodies should amend their patient information and guidance to state that IUI should be the first line treatment and that IVF should be offered only when essential. Reappraising and promoting IUI based on evidence enhances patient autonomy, choices, and trust, while allowing the fertility industry to operate within an ethical and acceptable framework not seen as exploitative toward vulnerable patients.

RESUMO

The empty follicle syndrome (EFS) is defined as a failure to aspirate any oocyte (s) from the follicles after ovarian hyperstimulation in preparation for IVF/ICSI. It is a frustrating and vague syndrome; and a controversial one concerning its existence, causes and possible treatment. Recurrent EFS or the recovery of immature oocytes thereafter is a more challenging problem. Delayed injection after leaving the immature oocytes for in vitro-maturation (IVM) has been suggested to be a possible option if immature oocytes are retrieved. Here, we present a case of repeated retrieval of a few immature oocytes after a first incidence of EFS. IVM was tried twice for those immature oocytes. Unfortunately, in this case IVM was unsuccessful and the oocytes failed to mature in vitro. Assistance is required for future management of these unfortunate couples.

RESUMO

BACKGROUND: Most studies carried out to evaluate recovery and development after porcine oocyte vitrification, reported better rates when cryopreserved in embryonic development stages or zygotes, but not in immature oocytes. For this reason, many studies are performed to improve immature oocyte vitrification protocols testing the use of different cryoprotectant concentrations, cooling devices, incubation times; but only a few of them have evaluated which fertilization procedure enhances blastocyst rates in vitrified oocytes. Therefore, this study was aimed to evaluate: 1) if the sperm selection with hyaluronic acid (HA) or polyvinylpyrrolidone (PVP) before injection could play a key role in increasing fertilization and blastocyst formation and 2) the embryo developmental ability and blastocyst production of porcine immature oocytes retrieved after vitrification-warming and co-cultured with granulosa cells during IVM, using different fertilization techniques: in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI) and conventional ICSI with hyaluronic acid (HA) sperm selection, known as physiological intracytoplasmic sperm injection (PICSI) and. RESULTS: Sperm selected with HA-PICSI displayed a higher percentage of live/acrosome reacted status compared to those in control and exposed to PVP. Higher dead/acrosome reacted rates were obtained after PVP exposure compared to control and HA. In oocytes, viability significantly decreased after IVM in vitrified oocytes. Besides, IVM rates were not different between control denuded oocytes cultured with granulosa cells (DO-GC) and vitrified oocytes. Regarding fertilization parameters, IVF showed higher percentages of total fertilization rate than those obtained by ICSI and PICSI. However, results demonstrate that PICSI fertilization increased the blastocysts formation rate in control DO-GC and vitrified oocytes compared to IVF and ICSI. CONCLUSIONS: To achieve high blastocyst formation rates from vitrified GV oocytes, it is recommended that sperm should be selected with HA instead of PVP before injection since high viability and acrosome reaction rates were obtained. Also, PICSI fertilization was the best method to produce higher blastocyst rates compared to the IVF and ICSI procedures.

RESUMO

Resumen OBJETIVO Evaluar los resultados en ciclos de FIV-ICSI de dos protocolos de estimulación ovárica en mujeres mayores de 35 años e investigar si agregar hormona luteinizante recombinante a FSH-r en un protocolo de estimulación mejora la respuesta ovárica y, en consecuencia, las tasas de embarazo en este grupo poblacional. MATERIALES Y MÉTODOS Estudio longitudinal, observacional y retrospectivo efectuado en pacientes de la Clínica de Reproducción Hisparep del Hospital Español con diagnóstico de infertilidad, mayores de 35 años, que recibieron un ciclo de hiperestimulación ovárica controlada con FIV-ICSI durante el periodo 2014-2016. El análisis estadístico se efectuó con la prueba de t de Student para muestras independientes. Los estudios se analizaron con el paquete estadístico SPSS IBM, versión 22. RESULTADOS Se analizaron 201 mujeres con infertilidad, mayores de 35 años. El grupo 1 (n = 101) de FIV-ICSI recibió estimulación con hormona folículo estimulante recombinante y hormona luteinizante recombinante 2:1 con menotropinas (Pergoveris® y Merapur®) a partir del segundo día del ciclo. El grupo 2 (n = 100) recibió hormona folículo estimulante recombinante y menotropinas (Gonal F® y Merapur®); en ambos esquemas se utilizó antagonista de GnRH a partir del día 7 del ciclo. La media de ovocitos aspirados fue de 7.5 en el grupo 1 y 9.1 en el grupo 2 (p = 0.058). La media de ovocitos maduros fue 6.2 en el Grupo 1 vs 7.4 en el grupo 2 (p = 0.085). La tasa de fecundación en el grupo 1 fue de 57 vs 67% en el grupo 2 (p = 0.045). En el grupo 1 la tasa de implantación por embrión transferido en fresco fue 24.1 vs 10.3% en el Grupo 2 (p = 0.40), la tasa de recién nacido vivo fue de 30% en el Grupo 1 vs 20.6% en el Grupo 2. La media de embriones vitrificados en el Grupo 1 fue 1.47 vs 1.38 en el Grupo 2. CONCLUSIONES La probable ventaja de la complementación con hormona folículo estimulante recombinante durante la estimulación ovárica en mujeres mayores de 35 años es de interés y se requiere su evaluación en estudios posteriores.


Abstract OBJECTIVE To evaluate the reproductive effects when recombinant luteinizing hormone is added and to compare two stimulation schemes by number of aspirated oocytes, mature oocytes, fertilization and implantation rates, live newborn and number of vitrified embryos. MATERIALS AND METHODS Longitudinal, observational and retrospective study carried out in patients of the Hisparep Reproduction Clinic of the Spanish Hospital with diagnosis of infertility, over 35 years old, who received a controlled ovarian hyperstimulation cycle with IVF-ICSI during the period 2014-2016. The statistical analysis was carried out with the Student t test for independent samples. The studies were analyzed with the IBM SPSS statistical package, version 22. RESULTS We analyzed 201 women with infertility, over 35 years of age. Group 1 (n = 101) of IVF-ICSI received stimulation with recombinant follicle-stimulating hormone and recombinant luteinizing hormone 2: 1 with menotropins (Pergoveris® and Merapur®) from the second day of the cycle. Group 2 (n = 100) received recombinant follicle stimulating hormone and menotropins (Gonal F® and Merapur®); in both schemes, GnRH antagonist was used from day 7 of the cycle. The average number of aspirated oocytes was 7.5 in Group 1 and 9.1 in Group 2 (p = 0.058). Mean mature oocytes were 6.2 in Group 1 vs 7.4 in Group 2 (p = 0.085). The fertilization rate in group 1 was 57 vs. 67% in Group 2 (p = 0.045). In Group 1 the implantation rate per embryo transferred fresh was 24.1 vs 10.3% in Group 2 (p = 0.40), the live newborn rate was 30% in Group 1 vs 20.6% in Group 2. The mean number of vitrified embryos in Group 1 was 1.47 vs 1.38 in Group 2. CONCLUSIONS The probable advantage of supplementation with recombinant follicle-stimulating hormone during ovarian stimulation in women over 35 years of age is of interest and its evaluation is required in subsequent studies.

RESUMO

OBJECTIVE: The present meta-analysis aimed to evaluate whether the freeze-all strategy (Freeze/All-ET) could bring about improvements in the clinical assisted reproductive technique (ART) outcomes when compared with the fresh embryo transfer strategy (Fresh-ET) in patients undergoing an ART cycle in accordance with the mean number of oocytes collected. METHODS: A systematic review based on electronic searches in databases (PubMed, EMBASE, Web of Science, SCOPUS, and Cochrane Central Register of Controlled Trials) was carried out to identify randomized controlled trails (RCTs) comparing ART outcomes between fresh-embryo transfers versus elective frozen-embryo transfers up to February of 2017. Four reviewers independently evaluated abstracts, validity assessment and data extraction. Odds Ratio (OR) values with a 95% confidence interval (CI), and heterogeneity were evaluated. RESULTS: Five RCTs were included as targets for data extraction and meta-analysis purposes. The results of this meta-analysis were divided into two parts (Freeze/All-ET versus Fresh-ET): Part I- All trials in which the mean number of collected oocytes was >12 and <21 for ongoing pregnancy rate (OR=1.24; 95%CI=1.06-1.44), clinical pregnancy rate (OR=1.19; 95%CI=0.98-1.43), live birth rate (OR= 1.39; 95%CI=0.99-1.95), and miscarriage rate (OR=0.68; 95%CI=0.46-1.00); Part II- Three studies where the mean number of oocytes retrieved was >12 and <15 for ongoing pregnancy rate (OR=1.17; 95%CI=1.00-1.38), clinical pregnancy rate (OR=1.34; 95%CI=0.79-2.28), live birth rate (OR= 1.24; 95%CI=1.00-1.55), and miscarriage rate (RR=0.68; 95%CI=0.46-1.02). CONCLUSIONS: The freeze-all strategy could be favorable when high numbers of oocytes are collected, signaling an association between higher ovarian stimulation and consequent impairment of endometrial receptivity. However, when the mean number of oocytes collected is <15, the freeze-all strategy does not appear to be advantageous.

RESUMO

PURPOSE: The purpose of this study is to evaluate the freeze-all strategy in subgroups of normal responders, to assess whether this strategy is beneficial regardless of ovarian response, and to evaluate the possibility of implementing an individualized embryo transfer (iET) based on ovarian response. METHODS: This was an observational, cohort study performed in a private IVF center. A total of 938 IVF cycles were included in this study. The patients were submitted to controlled ovarian stimulation (COS) with a gonadotropin-releasing hormone (GnRH) antagonist protocol and a cleavage-stage day 3 embryo transfer. We performed a comparison of outcomes between the fresh embryo transfer (n = 523) and the freeze-all cycles (n = 415). The analysis was performed in two subgroups of patients based on the number of retrieved oocytes: Group 1 (4-9 oocytes) and Group 2 (10-15 oocytes). RESULT(S): In Group 1 (4-9 retrieved oocytes), the implantation rates (IR) were 17.9 and 20.5% (P = 0.259) in the fresh and freeze-all group, respectively; the ongoing pregnancy rates (OPR) were 31 and 33% (P = 0.577) in the fresh and freeze-all group, respectively. In Group 2 (10-15 oocytes), the IR were 22.1 and 30.1% (P = 0.028) and the OPR were 34 and 47% (P = 0.021) in the fresh and freeze-all groups, respectively. CONCLUSION(S): Although the freeze-all policy may be related to better in vitro fertilization (IVF) outcomes in normal responders, these potential advantages decrease with worsening ovarian response. Patients with poorer ovarian response do not benefit from the freeze-all strategy.

RESUMO

Fertility preservation has become an important aspect of cancer treatment given the gonadotoxic effects of oncologic therapies. It is now considered standard of care to offer sperm banking to men undergoing treatment for primaries that affect young individuals. Less is known regarding fertility preservation of patients afflicted with prostate cancer. This cohort has progressively expanded and grown younger in the post-PSA era. Prostatectomy, radiation, chemotherapy and androgen blockade all pose unique challenges to the infertility specialist. Optimum management becomes even more uncertain for those men with metastatic prostate cancer. Most of these individuals will have received multiple forms of therapy, each carrying a distinct insult to the patient's reproductive potential. We describe a case of successful ex vivo sperm extraction and live birth in a patient previously treated with radiation and chronic androgen deprivation for metastatic prostate cancer. The presented case demonstrates that conception after radiation therapy and chronic androgen deprivation is feasible. We propose that fertility counselling and sperm cryopreservation should be considered for all prostate cancer patients. Additionally, for those individuals undergoing external beam radiotherapy, testicular shielding should be routinely offered in the event further family building is desired.

RESUMO

OBJECTIVE: Vitamin D deficiency has been largely related to infertility in animals. However, data demonstrating a direct association between hypovitaminosis D and infertility in humans are still conflicting. Increased body weight and an elevated body mass index (BMI) are known for their association with infertility. Therefore, this study attempted to verify whether increases in body weight and the BMI were associated with lower 25-hidroxyvitamin D [25(OH)D3] levels in the follicular fluid (FF) of patients treated for infertility with intracytoplasmic sperm injections (ICSI). This study aimed to assess the FF levels of 25(OH)D3 in women submitted to ICSI and correlate these levels with the different body weight and BMI values observed in the enrolled cohort. METHODS: The FF aspirates of 199 patients submitted to ICSI were collected after oocyte aspiration to check whether FF 25(OH)D3 levels were associated with weight regardless of the etiology of infertility. Chemiluminescent assays were used to assess FF 25(OH)D3 levels. The etiology of infertility was defined based on patient clinical history and follow-up. RESULTS: The patients enrolled in the study were divided into three groups according to their FF 25(OH)D3 levels, as follows: a) deficient (n=71; <20 ng/ml); b) insufficient (n=64; 21< 25(OH) D3>29 ng/ml); and c) sufficient (n=56 >30ng/ml) levels. Patients with lower FF 25(OH)D3 levels had a greater mean weight (64.1kg) when compared to patients with higher 25(OH)D3 levels (60.7kg), p<0.01. No differences were observed in terms of age or etiology of infertility. CONCLUSION: The body weight of the individuals with FF 25(OH)D3 deficiency measured in single follicles was significantly higher regardless of the etiology of infertility. Further epidemiologic and molecular studies are required to verify whether the amount of follicular 25(OH)D3 affects the outcome of IVF procedures.

RESUMO

Multinational data on assisted reproduction techniques undertaken in 2013 were collected from 158 institutions in 15 Latin American countries. Individualized cycle-based data included 57,456 initiated cycles. Treatments included autologous IVF and intracytoplasmic sperm injection (ICSI), frozen embryo transfers, oocyte donations. In autologous reproduction, 29.22% of women were younger than 35 years, 40.1% were 35-39 years and 30.6% were 40 years or older. Overall delivery rate per oocyte retrieval was 20.6% for ICSI and 25.4% for IVF. Multiple births included 20.7% for twins and 1.1% for triplets and over. In oocyte donations, twins reached 30% and triplets 1.4%. In singletons, pre-term births were 7.5%: 36.58% in twins and 65.52% in triplets. The relative risk for prematurity was 4.9 (95% CI 4.5 to 5.3) in twins and 8.7 (95% CI 7.6 to 10.0) in triplets and above. Perinatal mortality was 29.4 per 1000 in singletons, 39.9 per 1000 in twins and 71.6 per 1000 in high order multiples. Elective single embryo transfer represented only 2% of cycles, with delivery rate of 39.1% in women aged 34 years or less. Given the effect of multiple births and prematurity, it is mandatory to reduce the number of embryos transferred in the region.

RESUMO

OBJECTIVE: This study aimed to compare the use of semi-rigid and flexible catheters in terms of pregnancy rate and level of difficulty of the embryo transfer (ET) procedure. METHODS: Seven hundred and thirty-nine consecutive follicular aspirations for IVF or ICSI performed in our private fertility clinic within a 30-month period were randomly divided into two groups. Patients were allocated to either of the groups at the time of follicular retrieval with the aid of a random number generator according to the catheter used in ET: Group 1 (n = 370) - Frydman Classic Catheter 4.5 catheters; and Group 2 (n = 369) - Frydman Ultrasoft 4.5 catheters. Only patients offered ET in the randomized cycle were included (Group 1 = 363 and Group 2 = 340). Patients did not change groups after catheter allocation. Statistical analysis was carried out using an unpaired t-test or a chi square test as appropriate. Differences with P<0.05 were considered. RESULTS: A statistically significant difference in favor of the use of the Ultrasoft catheter was evident for parameters use of a tenaculum (19.8% vs. 5.9%) or a hysterometer (5.0% vs. 1.2%), presence of blood during post-ET inspection of the catheter (9.9% vs. 3.8%), and implantation rate (13.0% vs. 16.4%). Clinical pregnancy and delivery rates were comparable in both groups. CONCLUSION: Our results suggest that a softer catheter may help with difficult ETs. Softer catheters, as also reported by other authors, resulted in better implantation rates.

RESUMO

A atenção dada ao potencial reprodutivo diante o envelhecimento ovariano foi realçada pela tendência da mulher moderna de postergar a maternidade e pela procura cada vez maior por serviços de reprodução assistida. Nesse contexto, a avaliação da reserva folicular ovariana surge como tentativa de aferir sua capacidade funcional, melhor aconselhar os casais interessados e nortear protocolos de estimulação, para amenizar encargos emocionais e financeiros de um processo cujos resultados ainda se encontram aquém do desejado. Neste texto, abordam-se a situação atual de marcadores endócrinos basais e dinâmicos e os marcadores ecográficos comuns na avaliação da reserva ovariana em mulheres candidatas a ciclos assistidos.


The attention given to reproductive potential along ovarian ageing process has been enhanced with the trends of modern women to postpone maternity and due to progressive number of couples looking for assisted reproduction treatment. In this context, evaluation of ovarian follicular reserve has been taken into account, with the aim to determine gonadal functional capacity, to afford a better counselling of couples and to coordinate stimulation protocols, diminishing emotional and financial onuses of a complex process with still unsatisfactory results. The scope of this article is to briefly present current situation of basal and dynamic endocrine, and sonographic markers commonly used in ovarian reserve evaluation in candidates for assisted reproductive programs.

RESUMO

O diagnóstico genético pré-implantacional, associado a técnicas de reprodução assistida como a fertilização in vitro, permite a seleção de pré-embriões euploides para transferência. Nos últimos anos, tem sido indicado visando o aumento nas taxas de sucesso de tratamento, na sua forma de rastreio de aneuploidias para um grupo de pacientes de alto risco reprodutivo como: idade materna avançada, aborto recorrente e falhas repetidas de tratamentos. O objetivo desta revisão é avaliar o valor prognóstico da realização do diagnóstico genético pré-implantação, associado às técnicas de fertilização in vitro e injeção intracitoplasmática de espermatozoide (ICSI), revisar as limitações da técnica e sua eficácia. Embora este grupo com elevado risco reprodutivo apresente alta taxa de aneuploidia, não foram encontrados dados consistentes na literatura a favor da realização do rastreio genético de aneuploidias; portanto, ainda são necessários estudos com grupos mais bem definidos para que o diagnóstico genético pré-implantacional possa ser confirmado como uma ferramenta para aumento de taxas ou como procedimento de rotina, até sua eficácia ser provada.(AU)


The preimplantation genetic diagnosis associated with assisted reproduction technology, as in vitro fertilization, allows selecting euploid pre-embryos for transfer. In recent years, it has been performed as a screening tool for aneuploidy with the purpose of increasing reproductive rates in patient populations at high risk of aneuploidy, such as: advanced maternal age, recurrent pregnancy loss and repeated in vitro fertilization failures. The aim of this review is to evaluate the prognostic value of preimplantation genetic diagnosis, associated with in vitro fertilization and intracytoplasmic sperm injection (ICSI) techniques, to review technology?s limitations and its effectiveness. Although this high risk population group presents high rate of aneuploidy, this review has not shown consistently data in the literature in favor of preimplantation genetic screening; therefore, more studies with well-defined groups are still needed in order that preimplantation genetic diagnosis may be confirmed as a tool for increasing rates or as a routine procedure, until technique?s problems are solved and its effectiveness, proven.(AU)
