RESUMO

PURPOSE: While the literature has addressed the implementation of oncofertility care at developed institutions, minimal advice exists for those seeking to build oncofertility programs in limited resource settings (LRS). Our research offers a promising conversation on establishing oncofertility care in such settings from the perspective of a practitioner working to establish care in Latin America. We propose practices that have the potential to significantly improve access to and quality of care in these challenging settings. METHODS: PubMed was used to identify articles on fertility preservation (FP) in LRS for this narrative review. Eligible articles were published between January 2010 and May 2023, available in English and include two or more key phrases: "oncofertility care," "limited resources," "low-income settings," "limiting access," and "fertility preservation." RESULTS: As each institution faces a unique profile of medical, financial, geographical, cultural, and legal considerations, it is difficult to generalize an approach to optimizing care. However, the success of many programs is underpinned by collaborative efforts to educate and support healthcare specialists across the globe. National and international clinical guidelines, an unparalleled opportunity to promote the maintenance of a high level of care, do not exist for many Oncofertility practices. It is necessary that future guidelines consider barriers unique to implementing care in LRS as historically, guidelines have not done so, leaving LRS practitioners to deviate from the standard of care without consensus on how to best do so. CONCLUSION: It is crucial to consider the unique challenges in low-resource settings when strategizing the expansion of oncofertility efforts, optimizing care, and developing clinical guidelines. Addressing the diverse barriers to care requires multifaceted initiatives at local, national, and international levels.

RESUMO

OBJECTIVE: To investigate the perspectives of infertile couples regarding embryo cryopreservation throughout assisted reproduction treatment. METHODS: The convenience sample included infertile couples undergoing assisted reproduction treatment. They responded to a questionnaire specifically designed to gauge views and opinions on cryopreservation of surplus embryos. Statistical analysis was conducted using SPSS, employing the Mann-Whitney U and Fisher's exact tests (p<0.05). RESULTS: The study included 187 couples, with average ages of 35 years for women and 38 years for men. A total of 182 couples (97.3%) agreed with the practice of freezing surplus embryos and, the desire to increase the odds of pregnancy within the same ovarian stimulation cycle was the main motivation (89%). Almost 40% of participants said they might consider embryo donation to other couples for assisted reproductive treatment. However, less than 20% of volunteers (15.38% of women and 12.08% of men) expressed the desire to donate for research purposes. Women with higher levels of education were significantly (p<0.05) more likely to support the donation of surplus embryos for research. Gender, religion, and education did not influence (p>0.05) the respondents' perspectives regarding the beginning of life and posthumous conception. CONCLUSIONS: Embryo cryopreservation provides infertile couples with hope however, the fate of surplus embryos remains controversial. A careful approach with appropriate regulation is necessary to ensure safe and ethical practices.

RESUMO

OBJECTIVE: To use hashtag and content analysis to determine the prevalence, authorship, and types of fertility-related and oncofertility information shared on Instagram in Brazil. METHODS: Eleven fertility-related hashtags were chosen according to https://www.tagsfinder.com/: #infertility, #ivf, #endometriosis, #tryingotconceive, #maternity, #humanreproduction, #pregnancy, #invitrofertilization, #assistedreproduction, #pregnant, #difficulttogetpregnant. For oncofertility, the hashtags were #cancerandpregnancy, #oocytecryopreservation), #oncofertility, and #fertilitypreservation. Posts receiving over 20 comments in March 2021 were analyzed for topic and content. They were divided into six categories (educational, patient experience, outreach, emotional, social support, and coping mechanisms) before being analyzed by three authors. Authorship was divided into healthcare professionals (HCP) and lay people (LP). Posts not written in Brazilian Portuguese, videos, reposts of another account, and commercial posts were excluded. RESULTS: A total of 220 posts with fertility-related terms were analyzed. HCP accounted for 52% (n=114) and LP for 48% (n=106). Most HCP posts were made by medical doctors (n=78; 68.4%) and fertility clinics (n=27; 23.6%). Authorship analysis (HCP vs. LP) for each hashtag was as follows: #infertility (35% vs. 65%), #ivf (35% vs. 65%), #endometriosis (45% vs. 55%), #tryingtoconceive (65% vs. 35%), #maternity (LP 100%), #humanreproduction (20% vs. 80%), #pregnancy (95% vs. 5%), #invitrofertilization (50% vs. 50%), #assistedreproduction (5% vs. 95%), #pregnant (85% vs. 15%), #difficulttogetpregnant (5% vs. 95%). The category breakdown was as follows: 39% educational, 19% emotional, 16% social support, 13% patient experience, 9% coping, and 4% outreach. A total of 98 posts with #oncofertility were retrieved. Most (77.5%; n=62) were written by HCP. They fell into the following categories: 55% educational, 15% patient experience, 12.5% emotional, 11.2% support, and 3.2% coping. CONCLUSIONS: Both HCP and LP write about major fertility topics on Instagram. Oncofertility appears to gain less attention. In Brazil, educational content, followed by emotional content, prevails on Instagram.

RESUMO

El síndrome de Kartagener es una variante de la discinesia ciliar primaria, que consiste en una enfermedad hereditaria autosómica recesiva, poco frecuente, caracterizada por la tríada de bronquiectasias, sinusitis y dextrocardia. En este existen mutaciones en los genes responsables de la síntesis de proteínas ciliares, siendo el deterioro de la motilidad ciliar el principal problema fisiopatológico. Se presenta el caso de una paciente de 14 años de edad quien consulta por tos de tres semanas de evolución sin antecedentes de importancia, a quien como hallazgo incidental se le diagnostica dextrocardia. Por alta sospecha de síndrome de Kartagener, se solicitan estudios complementarios y se realiza broncoscopia que obtiene todos los componentes para un síndrome de Kartagener completo.

Kartagener syndrome is a variant of primary ciliary dyskinesia, which consists of a ra-re, autosomal recessive inherited disease, characterized by the triad of bronchiectasis, sinusitis and dextrocardia. In this case, there are mutations in the genes responsible for ciliary protein, with the deterioration of ciliary motility being the main pathophysiological problem. The case of a 14-year-old patient with a three-week history of cough with no significant history is presented. Dextrocardia was diagnosed as an incidental finding. Due to high suspicion of Kartagener syndrome, complementary studies were requested and bronchoscopy was performed, obtaining all the components for a complete Kartagener syndrome.

RESUMO

Prolactin (PRL) is a polypeptide hormone produced by the lactotrope cells of the anterior pituitary gland. Among its myriads of biological functions, PRL is the main regulator of mammary gland growth and development, as well as of the production and secretion of milk. Hyperprolactinemia represents a frequent consultation cause in medical practice. Nevertheless, elevations in serum PRL are not always pathological. Drug induced hyperprolactinemia is the most common cause, mainly by antipsychotics, followed by other causes such as pituitary neuroendocrine tumors, physiologic conditions, and systemic diseases such as chronic kidney disease and hypothyroidism. When evaluating a patient with hyperprolactinemia it is of utmost importance to consider the diverse etiologies of this condition in order to avoid unnecessary diagnostic workup and treatment. Regarding reproductive health, hyperprolactinemia is a well-documented cause of infertility, as approximately 15-20% of women undergoing infertility evaluation have hyperprolactinemia, which causes secondary amenorrhea, and other menstrual irregularities. Similarly, in men it is a cause of hypogonadism.

RESUMO

INTRODUCTION: The question of whether assisted reproductive technologies (ART) and ovulation induction are related to a higher incidence of ovarian tumors (OTs) is still controversial in the literature. METHODS: We performed a comprehensive search of PubMed, Embase, and Web of Science databases for case-control and cohort studies that investigated ART and ovulation induction exposure as risk factors for OT in infertile women. Odds ratios (OR) with 95% confidence intervals (CI) were employed for all endpoints. RESULTS: A total of nine case-control and twelve cohort studies were included, encompassing 439,477 women. ART was not associated with a higher risk of OTs (OR 1.05; 95% CI 0.86-1.29; p = 0.64; I2 = 36%), nor when considering only borderline OTs (OR 1.13; 95% CI 0.84-1.51; p = 0.42; I2 = 31%). In a subgroup analysis by study type, the risk difference of OTs remained non-significant for case-control (OR 1.12; 95% CI 0.70-1.78; p = 0.65; I2 = 60%) and cohort studies (OR 1.05; 95% CI 0.87-1.27; p = 0.60; I2 = 1%). For borderline OTs, the difference between groups was also non-significant for case-control studies (OR 1.44; 95% CI 0.73-2.87; p = 0.30; I2 = 40%) and cohort studies (OR 1.00; 95% CI 0.75-1.34; p = 0.99; I2 = 24%). CONCLUSION: In this systematic review and meta-analysis, ART exposure in infertile women was not associated with a higher risk of OTs in general or borderline tumors, even when accounting for study type differences.

RESUMO

PURPOSE: The continuous improvement and development of fertility care, internationally, requires ongoing monitoring of current delivery processes and outcomes in clinical practice. This descriptive and exploratory mixed-methods study was conducted in eight countries (Brazil, China, France, Germany, Italy, Mexico, Spain and the United Kingdom) to assess the unmet needs of fertility patients (male and female), and existing challenges, barriers and educational gaps of physicians and laboratory specialists involved in human fertility care during the COVID-19 pandemic. MATERIALS AND METHODS: The study was deployed sequentially in two phases: 1) in-depth 45-minute semi-structured interviews (n=76), transcribed, coded and thematically analysed using an inductive reasoning approach, 2) an online survey (n=303) informed by the findings of the qualitative interviews, face validated by experts in reproductive medicine, and analysed using descriptive and inferential statistical methods. RESULTS: The integrated results of both phases indicated numerous areas of challenges, including: 1) investigating male-related infertility; 2) deciding appropriate treatment for men and selective use of assisted reproductive technology; and 3) maintaining access to high-quality fertility care during a pandemic. CONCLUSIONS: The paper presents a reflective piece on knowledge and skills that warrant ongoing monitoring and improvement amongst reproductive medicine healthcare professionals amidst future pandemics and unanticipated health system disruptions. Moreover, these findings suggest that there is an additional need to better understand the required changes in policies and organizational processes that would facilitate access to andrology services for male infertility and specialized care, as needed.

RESUMO

OBJECTIVE: This study aimed to examine the behavior towards the acceptance of donor egg, donor sperm, and donor embryo of Northern Thai infertile couples, separated between men and women. METHODS: A cross-sectional study was conducted at the CMEx Fertility Center, Chiang Mai, Thailand. The questionnaires consisted of sociodemographic questions and the acceptance of couples toward donor egg, sperm and embryo. The couples filled in the answers separately. RESULTS: A total of 250 infertile couples were assessed. There were no differences in the acceptance rate of donor egg, sperm and embryo between the men and the women. Male acceptance rates were 25.6%, 18.8%, and 18.8%, respectively; while female acceptance rates were 24.4%, 18.4%, and 19.2%, respectively. Most couples (over 70%) concordantly rejected the donation program. Around 10% of couples had discordant answers. The concordance accepted for couples for donor egg, sperm and embryo was only 20%, 13.2%, and 14.8%. Older people and those who had been infertile for a longer period were significantly more likely to accept donation programs. CONCLUSIONS: There is no difference concerning the acceptance of donor gametes and embryo among men and women. Most participants reject the utilization of donor programs, the overall acceptance rate is relatively low. This may indicate the need for more adequate information and education for the community to enhance prevention programs rather than focus on the treatment with donor gametes or embryos.

RESUMO

Leptospirosis, caused by pathogenic spirochetes of the genus Leptospira spp., is a globally significant zoonotic disease that affects humans and animals. In cattle, leptospirosis is associated not only with overt clinical manifestations but also with reproductive diseases, including infertility. This study assesses the potential correlation between leptospirosis and infertility in Uruguayan beef cattle. A case-control study involved 31 beef herds with no prior history of Leptospira vaccination. In each herd, veterinarians identified 10 non-pregnant (cases) and 25 pregnant cows (controls) using ultrasound, and blood and urine samples were collected from each cow. Serological diagnosis was performed using the Microscopic Agglutination Test (MAT), and quantitative PCR (qPCR) was used to assess Leptospira excretion. Additionally, antibodies against bovine viral diarrhea virus (BVDV) and infectious bovine rhinotracheitis (IBR) were tested. The results demonstrated an association between seropositivity to the Sejroe serogroup (cut-off 1:200) and infertility in cattle (OR=1.31; p-value=0.06). Furthermore, the level of Leptospira excretion (qPCR) in urine was associated with increased infertility risk, with cows excreting over 100 copies per mL of urine having the highest odds of infertility (OR=2.34; p-value<0.01). This study suggests a potential association between leptospirosis and infertility in Uruguayan beef cattle, emphasizing the importance of both serological and molecular diagnostics for assessing reproductive health in cattle herds. Future research should explore the impact of Leptospira serogroups on other reproductive disorders in cattle.

RESUMO

Cryptorchidism (CO) or undescended testes is defined as the failure of one or both testes to be positioned inside the scrotum. Typically, cryptorchidism is detected at birth or shortly thereafter, and in humans, it is considered to be part of the testicular dysgenesis syndrome (TDS), a complex pathology regarding the male reproductive system that apparently involves the interaction of both genetic and environmental harmful factors, mainly during embryonic development. Serotonin (5-HT) is an ancient molecule that participates in a broad range of body functions, and in recent years, its importance in reproduction has started to be elucidated. In male pathologies such as infertility, varicocele, erectile dysfunction, and primary carcinoid tumors, an increase in 5-HT concentration or its metabolites in the blood, semen, and urine has been directly related; nevertheless, the role of 5-HT in CO remains unknown. In the present work, our goal was to answer two important questions: (1) whether some serotonergic system components are present in adult male Oryctolagus cuniculus (chinchilla rabbit) and (2) if there are changes in their expression in an experimental model of CO. Using histological, molecular, and biochemical approaches, we found the presence of some serotonergic system components in the adult chinchilla rabbit, and we demonstrated that its expression is downregulated after CO was pharmacologically induced. Although we did not test the role of 5-HT in the etiology of CO, our results suggest that this indoleamine could be important for the regulation of steroidogenesis and spermatogenesis processes in the chinchilla rabbit during adulthood. Finally, in parallel experimental series, we found downregulation of kynurenine concentration in COI rabbits when compared to control ones, suggesting that CO could be affecting the kynurenine pathway and probably testicular immune privilege which in turn could lead to infertility/sterility conditions in this disorder.

RESUMO

OBJECTIVE: The aim of this study was to determine the effect of anxiety and depression on pregnancy outcome in couples receiving in vitro fertilization treatment. METHODS: A total of 102 couples (102 females and 102 males) with unexplained infertility were included in the study. Personal Information Form was used to collect data, Case Follow-up Form to record the treatment process, and Spielberger's State-Trait Anxiety Inventory and Beck Depression Inventory to measure the anxiety and depression levels of couples. Couples were measured twice: before treatment and on oocyte pickup day. RESULTS: There was no statistically significant difference between the anxiety and depression levels and oocyte count of women (p>0.05). There were statistically significant differences between State-Trait Anxiety Inventory level and sperm count and between BID level and sperm motility (p<0.05). There was no statistically significant difference between the anxiety and depression levels and pregnancy outcomes of women (p>0.05). CONCLUSION: Anxiety and depression had no effect on pregnancy outcome. More studies are needed to investigate the effect of anxiety and depression on pregnancy outcome in unexplained infertility.

RESUMO

OBJECTIVE: Patients face challenges accessing fertility treatment due to barriers such as financial burdens, delayed referral to Reproductive Endocrinologists (REI), low medical literacy, language barriers and numerous other health disparities. Medicaid in New York offers coverage for office visits, blood tests, hysterosalpingograms (HSGs), and pelvic ultrasounds for infertility. The aim of this study is to delineate the characteristics of this underserved population and determine their ability to complete the initial fertility workup. METHODS: This was a retrospective study of all patients seeking fertility care at a single resident/fellow REI clinic in New York from September 2020 - January 2022. RESULTS: During the study period, 87 patients (avg age = 35.2y) sought care at the resident/fellow clinic over 126 appointments. The majority of patients had Medicaid insurance and most primary languages spoken included English (70.1%), Spanish (21.8%), and Bengali (3.4%). Documented Race was comprised of mostly Other (46%), African American (21.8%), Asian (17.2%), and White (11.5%). The majority of patients completed a lab workup (70-80%). Fewer patients underwent a scheduled HSG (59.8%) and patients' partners completed a semen analysis (SA) (27.6%). Overall, there was a significant difference in the ability to complete the initial infertility workup (lab tests vs. HSG vs. SA) across all groups regardless of age, insurance type, primary language spoken, race and ethnicity (p<0.05). CONCLUSIONS: Completing the fertility workup, particularly the male partner workup and imaging studies, can present challenges for underserved patients with infertility. Understanding which patient characteristics and societal factors restrict access to fertility care requires further investigation to improve access to fertility care in underserved communities.

RESUMO

Traumatic spinal cord injury (SCI) is a major cause of severe and permanent disability in young adults. Overweight and obesity are commonly observed among patients affected with SCI, with reports of a prevalence of over 60 and 30% respectively. Case report: A 34 year-old woman suffering from tetraplegia after sustaining a traumatic injury to C5-C6 at age 23 as a result of a motor vehicle accident was presented to our hospital's multidisciplinary bariatric team due to class II obesity. At the time of presentation to the team, eleven years after the accident, her BMI was calculated to be 39 Kg/m2 (weight 97 kg, height 1.57 meters). She was diagnosed with infertility while seeking pregnancy, and referred to our bariatric unit for weight loss. In addition, she had overcome the physical limitations of her injury, had a regular job and was engaged in regular physical activities such as swimming. In May 2017, she underwent laparoscopic sleeve gastrectomy (LSG) without complications and was discharged on postoperative day 2. 17 months following LSG, with a normal BMI, she became naturally pregnant. She had emergency cesarean at 35 weeks due to pneumonia but both patient and child recovered without sequelae. Currently, 4 years after surgery she maintains 37.11% total weight loss (weight 61 kg). She reports having a better quality of life with fewer medical intercurrencies. Conclusions: Patients with SCI and obesity, particularly women seeking to conceive, may be benefited by being referred to bariatric teams for assessment and treatment to improve results associated with sustained weight reduction.

RESUMO

The size-complexity rule posits that the evolution of larger cooperative groups should favour more division of labour. Examples include more cell types in larger multicellular organisms, and more polymorphic castes in larger eusocial colonies. However, a correlation between division of labour and group size may reflect a shared response of both traits to resource availability and/or profitability. Here, this possibility was addressed by investigating the evolution of sterile caste number (worker and soldier morphotypes) in termites, a major clade of eusocial insects in which the drivers of caste polymorphism are poorly understood. A novel dataset on 90 termite species was compiled from the published literature. The analysis showed that sterile caste number did increase markedly with colony size. However, after controlling for resource adaptations and phylogeny, there was no evidence for this relationship. Rather, sterile caste number increased with increasing nest-food separation and decreased with soil-feeding, through changes in worker (but not soldier) morphotype number. Further, colony size increased with nest-food separation, thus driving the false correlation between sterile caste number and colony size. These findings support adaptation to higher energy acquisition as key to the rise of complex insect societies, with larger size being a by-product.

RESUMO

OBJECTIVE: Postponing assisted reproductive technology treatment can cause pronounced mental health problems. The aim of this study was to examine the level of depression, anxiety, stress, and overall infertility-related distress experienced by infertile couples during the pandemic, as well as the differences between men and women in the examined variables and the correlations between them. METHODS: A total of 131 participants were included in the study, 65 men and 66 women. They were selected based on their responses in the Fertility Problems Inventory (FPI); the Depression, Anxiety, and Stress Scale-21 (DASS-21); and a general data questionnaire provided to them at the time of IVF. RESULTS: The levels of depression, anxiety, and stress in women and men resided within the normal range. Depression (p<0.05), anxiety (p<0.01), stress (p<0.01), and social concern (p<0.05) were more pronounced among women. Significant correlations were found between depression, anxiety, stress, and global stress and its three dimensions: social concern, sexual concern, and relationship concern. CONCLUSIONS: During the pandemic, women undergoing assisted reproductive technology treatment experienced significantly higher levels of depression, anxiety, stress, and overall infertility-related stress than men. Furthermore, depression, anxiety, and stress were apparently correlated with overall infertility-related stress.

RESUMO

Our main objective was to identify the male and female parameters associated with total fertilization failure (TFF) in IVF with nonmasculine indications. The present work, IRB equivalent INS 63209, is a case-control study that evaluated all cases with TFF after conventional IVF at the Center for Human Reproduction from January 2010 to December 2019 (n = 154). As a control group, we analyzed all patients who did not experience fertilization failure after conventional IVF in the same period (n = 475). We evaluated various parameters, both male and female, assessed during infertility treatment, and only cases without masculine etiology (normal seminal parameters) were included. Ages (female and male) were not different between the groups. Moreover, AMH (anti-Müllerian hormone), semen volume, preprocessing concentration and preprocessing motility were not significantly different (P > 0.05). However, the number of collected oocytes (study versus control groups, median [25-75 interquartile]: 2 [1-5] and 5 [3-8]); MII (2 [1-4] and 5 [2-7]); and postprocessing motility (85 [70-90] and 90 [80-95]) were significantly different between both groups (P < 0.05). Furthermore, a logistic regression analysis including all significant data demonstrated that the number of collected oocytes was significantly related to IVF failure. Patients with fewer than 5 oocytes had an OR of - 1.37 (- 0.938 to - 1.827) for TFF after conventional IVF. Our results showed that a lower follicular response to controlled ovarian stimulation, evidenced by a decreased number of collected oocytes, was the most important parameter associated with IVF failure in nonmasculine infertility.
