RESUMO

Sperm cryopreservation is a procedure widely used to store gametes for later use, to preserve fertility in patients prior to gonadotoxic treatments or surgery, and for sperm donation programs. The purpose of the study was to assess the impact of cryopreservation on human sperm transcriptome. Semen samples were collected from 13 normospermic men. Each sample was divided into two aliquots. The total RNA was immediately extracted from one aliquot. The second aliquot was frozen and total RNA was extracted after a week of storage in liquid nitrogen. The RNA samples were randomized in four pools, each of six donors, and analyzed by microarrays. The paired Significance Analysis of Microarray was performed. We found 219 lower abundant transcripts and 28 higher abundant transcripts in cryopreserved sperm than fresh sperm. The gene ontology analysis disclosed that cryopreservation alters transcripts of pathways important for fertility (i.e., spermatogenesis, sperm motility, mitochondria function, fertilization, calcium homeostasis, cell differentiation, and early embryo development), although the increase of some transcripts involved in immune response can compensate for the harmful effects of freezing.

RESUMO

PURPOSE: The COVID-19 pandemic and national lockdown from 9 March to 4 May 2020 changed social, familial, and sexual relationships, as well as how citizens interact with the health services. How these profound changes have affected sexuality, contraception and voluntary terminations of pregnancy is still largely undescribed. The main objective of this study was therefore to find out whether the COVID-19 pandemic and ensuing lockdown affected the demand for legal abortion. MATERIAL AND METHODS: The study period was divided into three phases: the pre-pandemic (January and February 2020); lockdown (March and April); and post-lockdown (May and June). The number and characteristics of women requesting pregnancy termination each month during that time were compared with the stats for the same months in the preceding three years (2017-2019). RESULTS: Immediately after national lockdown, the number of voluntary abortions markedly declined (-40.45%). The effect was more evident in women below 20 years of age (-66.67%), employed versus unemployed women (-42.71% vs. -21.05), and non-Italian versus Italian citizens (-53.01 vs. -32.85). No difference was found in the mean time from request to execution of the procedure, or in the type of the procedure used. CONCLUSION(S): National lockdown reduced the number of unwanted pregnancies, especially in younger women. The Italian health service's response to the demand appears to have been unaffected by the pandemic. However, as the demand for abortion is still high, probably due to unplanned pregnancies among cohabitants within a stable relationship, contraception guidance should be improved among women traditionally deemed low-risk in terms of sexual behaviour.

RESUMO

BACKGROUND: Healthy individuals and patients with cancer who are carriers of germline pathogenic variants in the BRCA1/2 genes face multiple reproductive challenges that require appropriate counseling and specific expertise. MAIN BODY: On December 5th-7th, 2019, patient advocates and physicians with expertise in the field of reproductive medicine, fertility preservation, and oncology were invited to "San Giuseppe Moscati" Hospital in Avellino (Italy) for a workshop on reproductive management of women with germline pathogenic variants in the BRCA1/2 genes. From the discussion regarding the current evidence and future prospective in the field, eight main research questions were formulated and eight recommendations were developed regarding fertility, fertility preservation, preimplantation genetic testing, and pregnancy in healthy carriers and patients with cancer. CONCLUSION: Several misconceptions about the topic persist among health care providers and patients often resulting in a discontinuous and suboptimal management. With the aim to offer patient-tailored counseling about reproductive issues, both awareness of current evidences and research should be promoted.

RESUMO

Data from both New York and London report a high prevalence of the asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnant patients admitted for delivery, raising questions on the possible correlated dangers (ie, contacts with healthcare workers; the possible creation of an intrahospital outbreak at birth; and conflicting evidence on vertical transmission). For this study, results from SARS-CoV-2 screening via nasopharyngeal swab from maternity wards of the four hospitals of Genoa, Italy, were collected during a month of complete lockdown from 1 April to 30 April 2020. Out of 333 tested women, only 9 were symptomatic. Only one symptomatic patient (0.3%) and six asymptomatic ones (1.8%) tested positive. Out of the six positive asymptomatic patients, five were from the most disadvantaged neighborhood of the city (assessed by postal code). In conclusion, even if Italy was badly affected by coronavirus disease 2019 in the studied month, the reported prevalence of SARS-CoV-2 infections in asymptomatic pregnant patients at term was lower than the ones reported in the literature.

RESUMO

STUDY QUESTION: Is there any association between the appearance of smooth endoplasmic reticulum aggregates (SERa) in oocytes and ovarian stimulation, embryological, clinical and neonatal outcomes of ICSI and IVF cycles? SUMMARY ANSWER: A suboptimal prolonged ovarian stimulation is detrimental to oocytes by inducing the occurrence of SERa, which reduces the reproductive potential of oocytes. WHAT IS KNOWN ALREADY: Controlled ovarian stimulation recruits oocytes of different qualities. Based on current evidence, it was agreed that non-homogeneous cytoplasm may represent the normal variability among oocytes rather than a dysmorphism with developmental significance. The only exception is the appearance of SERa within the ooplasm. Owing to the lack of univocal evidence in this literature about the safety of injecting oocytes with SERa and the mechanism responsible for the occurrence of SERa, this topic is still a matter of debate. STUDY DESIGN, SIZE, DURATION: A retrospective, longitudinal cohort study performed at a tertiary level public infertility center. We included 1662 cycles (180 SERa+ and 1482 SERa-) from 1129 women (age: 20-44 years) who underwent IVF/ICSI treatments in 2012-2019. The SERa+ cycles had at least one SERa+ oocyte in the oocyte cohort. The SERa- cycles had morphologically unaffected oocytes. PARTICIPANTS/MATERIALS, SETTING, METHODS: We collected stimulation data and embryological, clinical, neonatal outcomes of SERa- and SERa+ cycles and oocytes. MAIN RESULTS AND THE ROLE OF CHANCE: Overall, 347 out of 12 436 metaphase II oocytes (2.8%) were affected by SER. We performed only 12 transfers involving at least one SERa+ embryo. Stimulation length (P = 0.002), serum progesterone (P = 0.004) and follicle size (P = 0.046) at trigger, number of retrieved (P = 0.004) and metaphase II (P = 0.0001) oocytes were significantly higher in SERa+ than SERa- cycles. Fertilization rate was significantly (P < 0.0001) reduced in SERa+ cycles and oocytes compared to SERa- counterparts. Embryos of SERa+ cycles had a lower blastocyst formation rate compared to embryos of SERa- cycles (P = 0.059). Statistical analysis according to a generalized estimating equation model performed at patient level demonstrated that the duration of ovarian stimulation was predictive of SERa+ oocytes appearance. The clinical success of SERa+ cycles was lower than SERa- cycles, although no differences in neonatal birthweights or malformations were recorded in sibling unaffected oocytes of SERa+ cycles. LIMITATIONS, REASONS FOR CAUTION: Given that SERa+ oocytes were discarded in our center for years and transfers of embryos originating from affected oocytes were generally avoided, clinical outcomes of SERa+ cycles are largely attributable to the transfer of embryos derived from unaffected oocytes of SERa+ cycles and we did not have data about newborns from affected oocytes, since none of the transfers involving SERa+ embryos resulted in a progressive clinical pregnancy. WIDER IMPLICATIONS OF THE FINDINGS: For the first time, we speculate that the late-follicular phase elevated serum progesterone caused by a suboptimal prolonged ovarian stimulation may be detrimental to the oocytes by inducing the occurrence of SERa, resulting in negative effects on their reproductive potential. This raises the question of whether some stimulation regimens could be worse than others and a change in stimulation protocol would reduce the possibility of producing oocytes with suboptimal maturation. In particular, our data highlight the importance of correct timing of the trigger in order to maximize oocyte collection, not only in terms of numerosity but also their reproductive potential. STUDY FUNDING/COMPETING INTEREST(S): None. TRIAL REGISTRATION NUMBER: N/A.

RESUMO

Data on fertility after autologous hematopoietic stem cell transplantation (aHSCT) in women with multiple sclerosis (MS) are inconclusive. This study aims to report on post-aHSCT menstrual resumption in a multi-center MS-women cohort. Out of 43 women, 30 (70%) recovered menses after a mean time of 6.8 months. Older age (odds ratio (OR) = 0.5, p < 0.0001) and previous pulsed cyclophosphamide (OR = 0.44, p = 0.005) were independently associated with a reduced menstrual recovery probability. Conditioning regimens' intensity resulted not associated with post-procedure amenorrhea. Our results highlight younger age as significantly associated with menses recovery; proper fertility counseling for MS women candidated to aHSCT both prior- and post-transplantation is therefore warranted.

RESUMO

BACKGROUND: In assisted reproduction technology embryo competence is routinely evaluated on morphological criteria but efficacy remains relatively low. Additional information could be obtained by evaluating pronuclear (PN) morphology. Up to now controversial results have been reported about the prognostic value of PN score. One of the main limitations of literature data is the use of different PN classification methods. In this regard, in 2011 the ESHRE and Alpha Scientists in Reproductive Medicine defined three PN categories to standardize zygote assessment. In this study we evaluated whether the consensus ESHRE-Alpha system for the pronuclear scoring could be an useful additional criterion to improve prediction of embryo implantation potential. METHODS: This is a retrospective, longitudinal, observational, cohort study. We included 3004 zygotes from 555 women who underwent ICSI treatment at our Center between January 2014 and June 2019. The PN were categorized as score 1: symmetrical, 2: non-symmetrical, 3: abnormal. A subset of 110 zygotes did not cleaved. On day 2-3 1163 embryos were transferred, 232 arrested, and 9 were cryopreserved. Among the 1490 embryos cultured up to day 5-7, 516 became blastocysts: 123 were transferred on day 5 and 393 were cryopreserved. Comparisons of age, cleavage and blastocyst rate, quality of embryos, implantation success among PN score groups were evaluated by chi-square test or Kruskal-Wallis test as appropriate. Potential predictors of embryo implantation were first tested in univariable analysis using generalized estimating equations taking into account correlation between embryos originated from the same patient. Then, variables potentially associated with implantation success (P<0.05) were included in a multivariable analysis for calculating the adjusted odds ratio (OR) and 95% confidence interval (CI). RESULTS: There was no significant difference in patients'age, cleavage and blastulation rates, and embryo morphology among the three PNscore groups. The PN score 1-embryos had a greater implantation success respect to score 2-3-ones (OR 1.83; 95% CI 1.34-2.50, P=0.0001). Consistently, the pronuclear score remained predictive of implantation in top quality embryos (OR 1.68; 95%CI 1.17-2.42, P= 0.005). CONCLUSIONS: The consensus pronuclear score may be routinely included among criteria for embryo evaluation to increase patients' chance of becoming pregnant.

RESUMO

OBJECTIVE: Current literature suggests that cancer survivors are less likely to receive adequate contraception counseling. However, limited data existed on barriers to contraception usage in this population and on the efficacy of dedicated consultations. This study aims to describe how contraception is perceived by cancer survivors after counseling and acceptance rates of highly effective contraceptives. METHODS: We retrospectively analyzed clinical records from 313 consecutive cancer survivors at their first follow-up visit at the Oncofertility Unit of a tertiary hospital, from 2014 to 2019. Contraception acceptance and choice were examined stratified for the type of malignancy (hormone-sensible or not). A multivariate logistic regression model was used to evaluate possible predictors of acceptance. RESULTS: Thity-three women were excluded from the analysis because trying to conceive or already pregnant. Out of the remaining 280, only 9 (3.2%) asked spontaneously for contraception, in all the other visits the issue was brought up by the physician. After counseling 44.3% of the women without contraindications still opted out effective methods for fear of hormones or refusal of more medications. Age < 33 years and being in a relationship were correlated with acceptance. CONCLUSIONS: Even after a complete counseling in a dedicated service, fears of hormones and refusal of more medications remain strong issues for these patients. Family planning needs to be discussed with cancer survivors, preferably in the context of a long-term healthcare relationship. The Oncofertility Unit should become a privileged place for this type of counseling.

RESUMO

The COVID-19 pandemic is an unprecedented global situation. As assisted reproductive technology (ART) specialists, we should be cautious, carefully monitoring the situation while contributing by sharing novel evidence to counsel our patients, both pregnant women and would-be mothers. Time to egg collection and drop-out rates are critical parameters for scheduling treatments once the curve of infections has peaked and plateaued in each country. In order to reduce the values for these two parameters, infertile patients now require even more support from their IVF team: urgent oocyte collection for oncology patients must be guaranteed, and oocyte retrievals for women of advanced maternal age and/or reduced ovarian reserve cannot be postponed indefinitely. This document represents the position of the Italian Society of Fertility and Sterility and Reproductive Medicine (SIFES-MR) in outlining ART priorities during and after this emergency.

RESUMO

This study aims at detecting and evaluating differences in quantitative response to controlled ovarian stimulation (COS) with high doses of gonadotropins in women with low serum anti-Müllerian hormone (AMH). About 369 first cycles in a real-life scenario in women between 21 and 43 years old and with AMH ≤0.9 ng/ml were analyzed. Older women had a significantly worse outcome with respect to young women, not only qualitatively, but also in terms of quantitative ovarian response to COS [odd ratio (OR) to obtain at least three MII oocytes with each increasing year of female age: 0.89, 95% CI: 0.85 - 0.94; p < .001]. This study endorses that age is a significant factor when counseling patients with low AMH. AMH levels per se are not a reason to exclude patients from a COS treatment, since pregnancy and live birth can be achieved, especially in younger patients. However, with an AMH equally low, the ovarian response worsens with age, making questionable the effectiveness of a stimulation with high-dose gonadotropins in the older subgroup.

RESUMO

Failure modes and effects analysis (FMEA) is a proactive risk evaluation to identify and reduce potential failures that may occur during a procedure within a quality management programme. One of the procedures performed in assisted reproduction technology centres is testicular sperm extraction (TESE) as treatment of azoospermic patients. To examine the risks associated with the 'TESE management' process, we applied the FMEA method, before and after implementation of corrective measures defined in a standard operative procedure (SOP). A multidisciplinary team was formed. Possible causes of failures and their potential effects were identified, and risk priority number (RPN) for each failure was calculated. The FMEA team identified 4 process activities, 19 process steps and 19 potential failure modes. The re-evaluation after the corrective measures disclosed a reduction in the number of phases with high/moderate risk (pre-SOP: n = 13; post-SOP: n = 3). Improvements in the traceability system removed 11 out of 13 (85%) steps with a low risk of occurrence. In our experience, FMEA is efficient in helping multidisciplinary groups to strengthen knowledge and awareness on routine processes, identifying critical steps and planning practical improvements for a better compliance with criteria of traceability and conformity of biological samples and patients.

RESUMO

In ART, embryo quality evaluation is routinely based on morphological criteria. We previously demonstrated that the mitochondrial DNA (mtDNA)/genomic DNA (gDNA) ratio in culture medium was significantly associated with embryo quality and viability potential. The purpose of this prospective, blinded, multi-centric study was to validate the use of mtDNA/gDNA ratio in Day 3 spent medium as a predictor of human embryo developmental competence. The mtDNA/gDNA ratio was assessed in Day 3 culture media (n=484) of embryos from 143 patients by quantitative PCR. A mixed effect logistic regression model was applied. We found that mtDNA/gDNA ratio in Day 3 culture medium combined with embryo morphology improves the prediction upon blastulation compared to morphology alone (P < 0.0001), independent of patient and cycle characteristics. With regard to routine use in clinics, we evaluated the ability of the novel, combined grading score to improve selection of developmentally competent embryos of a single cohort. Including embryos from 44 patients, the sensibility and specificity of the scoring system based on Day 3 morphological stage were 92% and 13%, respectively. Integration with the culture medium mtDNA/gDNA ratio increased the performance of the method (sensibility: 95%; specificity: 65%). The results of this study suggest the possibility of carrying out a non-invasive evaluation of embryonic mtDNA content through the culture medium. When combined with embryo morphology, it has the potential to help embryologists rank embryos and choose which embryo(s) has the greater development potential, and thus should be transferred on Day 3, among sibling embryos with the same morphological grade.

RESUMO

STUDY QUESTION: Are there reasons that motivate young cancer survivors to ask for follow-up visits at an oncofertility unit? SUMMARY ANSWER: Cancer survivors request oncofertility follow-up visits for the management of treatment-related side effects or ovarian reserve evaluation, even if not (or not yet) wishing for a pregnancy. WHAT IS KNOWN ALREADY: Personalised oncofertility counselling before gonadotoxic therapies is considered standard of care for young women with newly diagnosed cancer. However, the long-term follow-up of these patients in an oncofertility unit is not described in the literature other than for the use of cryopreserved material. STUDY DESIGN, SIZE, DURATION: We retrospectively examined rates and reasons for the first follow-up visits of 154 consecutive young female cancer patients (age range: 18-40 years) who underwent a pre-treatment consultation between January 2012 and June 2017. Demographic and clinical data were collected, as well as information about the chosen fertility preservation method, if any. PARTICIPANTS/MATERIALS, SETTING, METHODS: Rates and reasons for follow-up visits were collected and expressed as percentages. Different reasons were examined in the whole cohort and stratified for type of malignancy. Possible predictive factors for return to the follow-up visit (age, nulliparity, presence of a partner, neoplasm, having cryopreserved material) were investigated through logistic regression. MAIN RESULTS AND THE ROLE OF CHANCE: Out of 154 patients, 74 returned to the oncofertility unit (48.1%) for a follow-up visit. The first visit was requested mostly at the end of anticancer therapies (51.3% versus 40.5% during therapies and 8.1% after cancer relapse). Among these patients, only 10.8% returned for the first time because they were actively desiring a pregnancy. For the others, the most common reasons for consultations were management of gynecological adverse effects of therapies (29.7%) and evaluation of ovarian reserve not linked to an immediate desire for a pregnancy (39.2%). Other patients asked for contraception (4.1%), menopause counselling (5.4%), or new fertility preservation counselling because of cancer relapse (10.8%). None of the examined factors were significantly predictive of return to the oncofertility unit. LIMITATIONS, REASONS FOR CAUTION: These findings represent the experience of a single centre. A longer duration of follow-up would be needed to provide more precise information on this regard. WIDER IMPLICATION OF THE FINDINGS: The role of an oncofertility unit should not be limited to proposing fertility preservation procedures. In the management of young adult cancer patients, the reproductive medical specialist should be considered a key figure not only before but also during and after anticancer treatments to explore salient aspects of gynecological and reproductive health. STUDY FUNDING/COMPETING INTEREST(S): This research did not receive any specific funding. M.L. served as a consultant for Teva and received honoraria from Theramex outside the submitted work. The other authors declare no conflict of interest. TRIAL REGISTRATION NUMBER: N.A.

RESUMO

This study aims to evaluate levels of anxiety and depression in women, correlated with infertility per se and with infertility treatments, highlighting predictors of higher levels of distress. Two validated standardized questionnaires, the Hospital Anxiety and Depression Scale (HADS) and the Fertility Quality of Life (FertiQoL), were administered to 89 women both before their first cycle of infertility treatment and again at the end of the ovarian stimulation for in vitro fertilization (IVF). Women's levels of anxiety were significantly higher before the treatment than during the treatment itself. Stratifying the women in three groups based on principal cause of infertility (male infertility, female infertility, or both male and female), we found significantly higher levels of anxiety and general distress in patients under treatment for female infertility. Higher anxiety levels in our sample before the treatment are probably an effect of not knowing what they are expected to do to solve their problem. Moreover, when the cause of infertility is exclusively female, women experience higher levels of anxiety and general distress both before and during the treatment, probably correlated to a sense of guilt. These data help the treating physician to better counsel patients and to provide a more focused psychological support.

RESUMO

We here report a successful healthy childbirth and an ongoing evolutive pregnancy in a case of partial globozoospermia after selection of mature spermatozoa bound to hyaluronic acid (HA). The couple underwent two in vitro fertilisation (IVF) cycles. In the first attempt, 14 MII oocytes were retrieved. Randomly, seven oocytes were injected by conventional PVP-ICSI and seven by HA-ICSI. Fertilised oocytes were 2/7 and 4/7 after PVP-ICSI and HA-ICSI respectively. Transfer of two grade A embryos from HA-ICSI lead to birth of a healthy baby. The surplus embryo of the HA-ICSI group was vitrified at blastocyst stage. The two embryos from PVP-ICSI arrested their development. Two years after the childbirth, the vitrified blastocyst was transferred into the uterus, but implant failed. In the second cycle, 14 MII oocytes were retrieved and they were injected by HA-ICSI. Fertilised oocytes were 10 out of 14 injected oocytes. On day 5, two blastocysts were transferred into uterus and a single evolutive pregnancy is ongoing. On day 6, one blastocyst was vitrified. The remaining surplus embryos arrested their development. A healthy childbirth and an ongoing evolutive pregnancy in two consecutive ICSI attempts of the same couple suggest that HA sperm selection might assist in cases with partial globozoospermia.

RESUMO

BACKGROUND: Ovaries are sensitive to chemotherapy, which may lead to early depletion of primordial follicle reserve. One strategy for gonadal function preservation is temporary ovarian suppression with Gonadotropin Releasing Hormone agonists (GnRHa) during chemotherapy. To date, GnRHa protective mechanism of action remains not fully elucidated. METHODS: We collected 260 immature cumulus cell-oocyte complexes (COC) from 111 women < 38 years old, with a normal ovarian reserve. The COC were randomly assigned to the following groups: a) control; culture with the addition of b) GnRHa; c) cyclophosphamide; d) cyclophosphamide plus GnRHa. After in vitro treatments, RNA and proteins were extracted from oocytes and cumulus cells (CC), separately. Potential effects of drugs were evaluated on GnRH receptors, apoptosis pathways, ceramide pathway, and glutathione synthesis by quantitative PCR and, whenever possible, by Western blot. RESULTS: Cyclophosphamide triggered activation of the extrinsic pathway of apoptosis mediated by BAX in CC. The co-administration of GnRHa inhibited the apoptosis pathway in CC. According to our model, the GnRHa does not directly act on oocytes, which do not express GnRH receptors. Moreover, glutathione synthesis was decreased after GnRHa treatment both in CC and oocytes. CONCLUSION: Our data suggest that the protective mechanisms induced by GnRHa is mediated by an anti-apoptotic effect on CC.

RESUMO

STUDY QUESTION: Does the presence of aggregates of smooth endoplasmic reticulum (SERa) impact the transcriptome of human metaphase II (MII) oocytes?. SUMMARY ANSWER: The presence of SERa alters the molecular status of human metaphase II oocytes. WHAT IS KNOWN ALREADY: Oocytes presenting SERa are considered dysmorphic. Oocytes with SERa (SERa+) have been associated with reduced embryological outcome and increased risk of congenital anomalies, although some authors have reported that SERa+ oocytes can lead to healthy newborns. The question of whether or not SERa+ oocytes should be discarded is still open for debate, and no experimental information about the effect of the presence of SERa on the oocyte molecular status is available. STUDY DESIGN, SIZE, DURATION: This study included 28 women, aged <38 years, without any ovarian pathology, and undergoing IVF treatment. Supernumerary MII oocytes with no sign of morphological alterations as well as SERa+ oocytes were donated after written informed consent. A total of 31 oocytes without SERa (SERa-) and 24 SERa+ oocytes were analyzed. PARTICIPANTS/MATERIALS, SETTING, METHODS: Pools of 8-10 oocytes for both group were prepared. Total RNA was extracted from each pool, amplified, labeled and hybridized on oligonucleotide microarrays. Analyses were performed by R software using the limma package. MAIN RESULTS AND THE ROLE OF CHANCE: The expression profiles of SERa+ oocytes significantly differed from those of SERa- oocytes in 488 probe sets corresponding to 102 down-regulated and 283 up-regulated unique transcripts. Gene Ontology analysis by DAVID bioinformatics disclosed that genes involved in three main biological processes were significantly down-regulated in SERa+ oocytes respective to SERa- oocytes: (i) cell and mitotic/meiotic nuclear division, spindle assembly, chromosome partition and G2/M transition of mitotic cell cycle; (ii) organization of cytoskeleton and microtubules; and (iii) mitochondrial structure and activity. Among the transcripts up-regulated in SERa+ oocytes, the most significantly (P = 0.002) enriched GO term was 'GoLoco motif', including the RAP1GAP, GPSM3 and GPSM1 genes. LARGE SCALE DATA: Raw microarray data are accessible through GEO Series accession number GSE106222 (https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE106222). LIMITATIONS, REASONS FOR CAUTION: Data validation in a larger cohort of samples would be beneficial, although we applied stringent criteria for gene selection (fold-change >3 or <1/3 and FDR < 0.1). Surveys on clinical outcomes, malformation rates and follow-up of babies born after transfer of embryos from SERa+ oocytes are necessary. WIDER IMPLICATIONS OF THE FINDINGS: We provide information on the molecular status of SERa+ oocytes, highlighting possible associations between presence of SERa, altered oocyte physiology and reduced developmental competence. Our study may offer further information that can assist embryologists to make decisions on whether, and with what possible implications, SERa+ oocytes should be used. We believe that the presence of SERa should be still a 'red flag' in IVF practices and that the decision to inseminate SERa+ oocytes should be discussed on a case-by-case basis. STUDY FUNDING/COMPETING INTEREST(s): This study was partially supported by Ferring Pharmaceuticals. The authors have no conflicts of interest to declare.

RESUMO

BACKGROUND: Fertility and pregnancy issues are of key importance for young breast cancer patients. Despite several advances in the field, there are still multiple unmet needs and barriers in discussing and dealing with these concerns. To address the significant challenges related to fertility and pregnancy issues, the PREgnancy and FERtility (PREFER) study was developed as a national comprehensive program aiming to optimize care and improve knowledge around these topics. METHODS: The PREFER study is a prospective cohort study conducted across several Italian institution affiliated with the Gruppo Italiano Mammella (GIM) group evaluating patterns of care and clinical outcomes of young breast cancer patients dealing with fertility and pregnancy issues. It is composed of two distinctive studies: PREFER-FERTILITY and PREFER-PREGNANCY. The PREFER-FERTILITY study is enrolling premenopausal patients aged 18-45 years, diagnosed with non-metastatic breast cancer, who are candidates to (neo)adjuvant chemotherapy and not previously exposed to anticancer therapies. The primary objective is to obtain and centralize data about patients' preferences and choices towards the available fertility preserving procedures. The success and safety of these strategies and the hormonal changes during chemotherapy and study follow-up are secondary objectives. The PREFER-PREGNANCY study is enrolling survivors achieving a pregnancy after prior history of breast cancer and patients diagnosed with pregnancy-associated breast cancer (PABC). The primary objectives are to obtain and centralize data about the management and clinical outcomes of these women. Patients' survival outcomes, and the fetal, obstetrical and paediatric care of their children are secondary objectives. For both studies, the initial planned recruitment period is 5 years and patients will remain in active follow-up for up to 15 years. The PREFER-FERTILITY study was first activated in November 2012, and the PREFER-PREGNANCY study in May 2013. DISCUSSION: The PREFER study is expected to support and improve oncofertility counseling in Italy, to explore the real need of fertility preserving procedures, and to acquire prospectively more robust data on the efficacy and safety of the available strategies for fertility preservation, on the management of breast cancer survivors achieving a pregnancy and of women with PABC (including the possible short- and long-term complications in their children). TRIAL REGISTRATION NUMBER: ClinicalTrials.gov identifier: NCT02895165 (Retrospectively registered in August 2016).

RESUMO

We describe successful controlled ovarian stimulation (COS) and the first known IVF pregnancy in a trisomy X carrier with associated hypogonadotropic hypogonadism (HH) linked to a chromosome 4 double mutation in the allele of the Gonadotropins Releasing Hormone receptor (GnRHr) gene. Previous administration of low dose of gonadotropins, as recommended in patients with HH, led to poor follicular recruitment. Since trisomy X is a risk factor for diminished ovarian reserve (DOR) and premature ovarian insufficiency (POI), higher doses of gonadotropins led to better ovarian response. The report readknowledges the importance of a correct genetic evaluation in a competent laboratory as a reliable base for treatment planning in this kind of patients.

RESUMO

In the last years, thanks to the improvement in the prognosis of cancer patients, a growing attention has been given to the fertility issues. International guidelines on fertility preservation in cancer patients recommend that physicians discuss, as early as possible, with all patients of reproductive age their risk of infertility from the disease and/or treatment and their interest in having children after cancer, and help with informed fertility preservation decisions. As recommended by the American Society of Clinical Oncology and the European Society for Medical Oncology, sperm cryopreservation and embryo/oocyte cryopreservation are standard strategies for fertility preservations in male and female patients, respectively; other strategies (e.g. pharmacological protection of the gonads and gonadal tissue cryopreservation) are considered experimental techniques. However, since then, new data have become available, and several issues in this field are still controversial and should be addressed by both patients and their treating physicians.In April 2015, physicians with expertise in the field of fertility preservation in cancer patients from several European countries were invited in Genova (Italy) to participate in a workshop on the topic of "cancer and fertility preservation". A total of ten controversial issues were discussed at the conference. Experts were asked to present an up-to-date review of the literature published on these topics and the presentation of own unpublished data was encouraged. On the basis of the data presented, as well as the expertise of the invited speakers, a total of ten recommendations were discussed and prepared with the aim to help physicians in counseling their young patients interested in fertility preservation.Although there is a great interest in this field, due to the lack of large prospective cohort studies and randomized trials on these topics, the level of evidence is not higher than 3 for most of the recommendations highlighting the need of further research efforts in many areas of this field. The participation to the ongoing registries and prospective studies is crucial to acquire more robust information in order to provide evidence-based recommendations.
