How phytochemicals influence reproductive outcomes in women receiving assisted reproductive techniques: a systematic review.

CONTEXT: Over the past few years, there has been an increasing amount of scholarly literature suggesting a connection between the nutritional status of pregnant mothers and early fetal development, as well as the long-term health consequences of their offspring. Multiple studies have documented that alterations in dietary patterns prior to conception have the potential to affect the initial stages of embryonic development. OBJECTIVES: The aim of this study was to perform a comprehensive review of the research pertaining to the correlation between phytochemicals ( specifically, polyphenols, carotenoids and phytoestrogens) and assisted reproductive technology (ART). DATA SOURCES: PubMed, Scopus, Web of Science, and Clinical Trials databases were searched from January 1978 to March 2023. STUDY SELECTION: This study comprised observational, randomized controlled, and cohort studies that examined the effects of phytochemicals on ART results. The study's outcomes encompass live birth rate, clinical pregnancy, and ongoing pregnancy. DATA EXTRACTION: The assessment of study quality was conducted by 2 researchers, independently, using the Quality Criteria Checklist for Primary Research. RESULTS: A total of 13 studies were included, of which there were 5 randomized controlled studies, 1 nonrandomized controlled study, 6 prospective cohort studies, and 1 retrospective cohort study. CONCLUSION: This research focused on investigating the impact of phytochemicals on ART and has highlighted a dearth of articles addressing that topic. Collaboration among patients, physicians, and nutritionists is crucial for doing novel research. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42023426332.

Reproductive outcomes in patients with high levels of sperm DNA fragmentation using testicular sperm for intracytoplasmic injection: a retrospective analysis.

This study aims to compare the embryological and clinical parameters of intracytoplasmic sperm injection (ICSI) cycles using testicular versus ejaculated sperm in male patients with elevated sperm DNA fragmentation (SDF). A total of 73 ICSI cycles were examined in couples where the male partner exhibited high levels of SDF. ICSI was performed using either ejaculated or testicular sperm. The primary outcomes were rates of blastocyst formation, high-quality embryo development, and clinical pregnancy. The DNA fragmentation index (DFI) for testicular sperm (16.81 ± 17.51) was significantly lower than that of ejaculated sperm (56.96 ± 17.56). While the blastocyst formation rate was significantly higher in the testicular sperm group compared to the ejaculated sperm group, no statistically significant differences were noted in fertilization rate (72.15% vs. 77.23%), rate of high-quality embryo formation (47.17% vs. 46.53%), clinical pregnancy (50% vs. 56.52%), Cumulative pregnancy (70.2% vs. 55.6%), or live birth rate (43.75% vs.43.48%). Testicular spermatozoa have no additional advantage over ejaculated spermatozoa except for blastocyst quality in patients with high SDF, the use of testicular spermatozoa for the first ICSI cycle in male infertility patients with high SDF should be undertaken after much consideration at present.

Assisted reproductive technologies and postpartum depressive symptoms: A meta-analysis.

BACKGROUND: Assisted reproductive technologies (ARTs) have become the main treatment for infertility. ART treatment can be a stressful life event for infertile females. Whether there is an association between ARTs and postpartum depressive symptoms (PDS) has not been established. METHODS: PubMed, MEDLINE, EMBASE, PsycINFO, and CNKI were searched. The pooled outcome was the difference in incidence of PDS within 1 year postpartum between ARTs and the spontaneous pregnancy group. RESULTS: A total of 12 cohort studies, which were conducted in eight developed countries and two developing countries, were involved. In total, 106,338 pregnant women, including 4990 infertile females with ARTs treatment and 101,348 women with spontaneous pregnancy, were enrolled in our final analysis. ARTs women had a lower incidence of PDS compared to the spontaneous pregnancy group according to a random effect model (OR = 0.83, 95 % CI: 0.71-0.97, p = 0.022, I2 = 62.0 %). Subgroup analyses indicated that studies on late PDS (follow-up: 3-12 months postpartum) were more heterogeneous than those on early PDS (follow-up: <3 months postpartum) (I2 = 24.3 % vs. I2 = 0 %, interaction p-value < 0.001). There was a strong relationship between ARTs and late PDS (OR = 0.65, 95 % CI: 0.55-0.77, p < 0.001). Therefore, the possible source of heterogeneity was the postpartum evaluation time, which was confirmed by post-hoc meta-regression. LIMITATIONS: Some underlying confounders, such as previous psychiatric illness, the limited availability of ARTs, and ethnic disparities, cannot be ignored and may have biased interpretation of the results. CONCLUSION: The available data suggested that ARTs were associated with lower incidence of PDS, especially when follow-up lasted over 3 months. However, these findings should be interpreted with caution. Better-designed trials are needed to confirm this association.

Efficacy and safety of follitropin delta versus follitropin alpha/beta in infertility treatment: A systematic review and meta-analysis.

Background: Follitropin δ may be an alternative to conventional follitropin α/ß for controlled ovarian stimulation (COS) within assisted reproductive treatment (ART), but its efficacy and safety remain unknown. We performed a random-effects meta-analysis to compare the efficacy and safety of follitropin δ and follitropin α/ß. Methods: We searched randomized controlled trials comparing follitropin δ and follitropin α/ß using MEDLINE, Embase, CENTRAL, ClinicalTrials.gov, and WHO-ITCRP on December 14, 2022. The primary outcomes were the live birth rate and the incidence of moderate or severe ovarian hyperstimulation syndrome (OHSS). The certainty of the evidence was assessed using the grading of recommendations assessment, development, and evaluation approach. The protocol was registered on the Open Science Framework. Results: Three studies involving 2682 participants were included in our meta-analysis. The results indicated that follitropin δ may result in little to no difference in live birth rates (risk ratio [RR], 1.12; 95% confidence interval [CI], 0.91-1.38; low certainty) and the incidence of moderate or severe OHSS (RR, 0.78; 95% CI, 0.48-1.26; low certainty) compared with follitropin α/ß. Conclusion: Follitropin δ may result in little to no difference in COS compared with follitropin α/ß, especially in terms of live births and safety.

Fertility preservation counseling for women of reproductive age diagnosed with cancer: an integrative review.

This integrative review synthesizes the scientific evidence on fertility preservation counseling prior to oncological treatment for women of reproductive age diagnosed with cancer. Bibliographic research was conducted on databases PubMed, CINAHL, LILACS, EMBASE, Scopus, and Web of Science. The structured search strategy for the review question was "counseling AND antineoplastic agents AND fertility preservation". The use of controlled descriptors and keywords was adapted for each database. Study selection through the Rayyan platform was independent and blinded. The final sample comprised seven studies emphasizing the importance of clarifying factors related to the risk of infertility due to oncological treatment and fertility preservation techniques, such as success rate, pregnancy rate, cost, available options, and side-effects, as well as discussing the possibilities of adoption and surrogacy. This review provided evidence reinforcing the importance of counseling for fertility preservation, promoting motherhood for women who face oncological treatment. Organized networks linking oncology and reproductive medicine units are crucial to facilitate patient referral between these services and interprofessional communication.

Follicular Fluid-Derived Extracellular Vesicles Influence on In Vitro Maturation of Equine Oocyte: Impact on Cumulus Cell Viability, Expansion and Transcriptome.

Cumulus cell (CC) expansion is pivotal for oocyte maturation, during which CCs release factors that initiate paracrine signaling within the follicular fluid (FF). The FF is abundant in extracellular vesicles (EVs) that facilitate intercellular communication. Although bovine and murine EVs can control cumulus expansion, these effects have not been observed in equines. This study aimed to assess the impact of FF-derived EVs (ffEVs) on equine CC expansion, viability, and transcriptome. Cumulus-oocyte complexes (COCs) that underwent in vitro maturation (IVM) in the presence (200 µg protein/mL) or absence (control) of ffEVs were assessed for cumulus expansion and viability. CCs were isolated after 12 h of IVM, followed by RNA extraction, cDNA library generation, and subsequent transcriptome analysis using next-generation sequencing. Confocal microscopy images illustrated the internalization of labeled ffEVs by CCs. Supplementation with ffEVs significantly enhanced cumulus expansion in both compacted (Cp, p < 0.0001) and expanded (Ex, p < 0.05) COCs, while viability increased in Cp groups (p < 0.01), but decreased in Ex groups (p < 0.05), compared to the controls. Although transcriptome analysis revealed a subtle effect on CC RNA profiles, differentially expressed genes encompassed processes (e.g., MAPK and Wnt signaling) potentially crucial for cumulus properties and, consequently, oocyte maturation.

Economic evaluations of assisted reproductive technologies in high-income countries: a systematic review.

STUDY QUESTION: Which assited reproductive technology (ART) interventions in high-income countries are cost-effective and which are not? SUMMARY ANSWER: Among all ART interventions assessed in economic evaluations, most high-cost interventions, including preimplantation genetic testing for aneuploidy (PGT-A) for a general population and ICSI for unexplained infertility, are unlikely to be cost-effective owing to minimal or no increase in effectiveness. WHAT IS KNOWN ALREADY: Approaches to reduce costs in order to increase access have been identified as a research priority for future infertility research. There has been an increasing number of ART interventions implemented in routine clinical practice globally, before robust assessments of evidence on economic evaluations. The extent of clinical effectiveness of some studied comparisons has been evaluated in high-quality research, allowing more informative decision making around cost-effectiveness. STUDY DESIGN, SIZE, DURATION: We performed a systematic review and searched seven databases (MEDLINE, PUBMED, EMBASE, COCHRANE, ECONLIT, SCOPUS, and CINAHL) for studies examining ART interventions for infertility together with an economic evaluation component (cost-effectiveness, cost-benefit, cost-utility, or cost-minimization assessment), in high-income countries, published since January 2011. The last search was 22 June 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS: Two independent reviewers assessed publications and included those fulfilling the eligibility criteria. Studies were examined to assess the cost-effectiveness of the studied intervention, as well as the reporting quality of the study. The chosen outcome measure and payer perspective were also noted. Completeness of reporting was assessed against the Consolidated Health Economic Evaluation Reporting Standard. Results are presented and summarized based on the intervention studied. MAIN RESULTS AND THE ROLE OF CHANCE: The review included 40 studies which were conducted in 11 high-income countries. Most studies (n = 34) included a cost-effectiveness analysis. ART interventions included medication or strategies for controlled ovarian stimulation (n = 15), IVF (n = 9), PGT-A (n = 7), single embryo transfer (n = 5), ICSI (n = 3), and freeze-all embryo transfer (n = 1). Live birth was the mostly commonly reported primary outcome (n = 27), and quality-adjusted life years was reported in three studies. The health funder perspective was used in 85% (n = 34) of studies. None of the included studies measured patient preference for treatment. It remains uncertain whether PGT-A improves pregnancy rates compared to IVF cycles managed without PGT-A, and therefore cost-effectiveness could not be demonstrated for this intervention. Similarly, ICSI in non-male factor infertility appears not to be clinically effective compared to standard fertilization in an IVF cycle and is therefore not cost-effective. Interventions such as use of biosimilars or HMG for ovarian stimulation are cheaper but compromise clinical effectiveness. LIMITATIONS, REASONS FOR CAUTION: Lack of both preference-based and standardized outcomes limits the comparability of results across studies. The selection of efficacy evidence offered for some interventions for economic evaluations is not always based on high-quality randomized trials and systematic reviews. In addition, there is insufficient knowledge of the willingness to pay thresholds of individuals and state funders for treatment of infertility. There is variable quality of reporting scores, which might increase uncertainty around the cost-effectiveness results. WIDER IMPLICATIONS OF THE FINDINGS: Investment in strategies to help infertile people who utilize ART is justifiable at both personal and population levels. This systematic review may assist ART funders decide how to best invest to maximize the likelihood of delivery of a healthy child.

Assisted reproductive technologies could be associated with higher risk of parenting difficulties in women with postpartum major depression.

No increased risk of postpartum major depression (PPMD) was reported in women conceiving through assisted reproductive technologies (ART). However, ART may be associated with a higher risk of parenting difficulties in women with PPMD. In 359 women with a PPMD admitted to a Mother-Baby Unit (MBU), ART-women (4.2%) showed a 5-fold higher rate of parenting difficulties than those with spontaneous pregnancy (73.33% vs. 35.17%, multivariate ORa = 5.09 [1.48-17.48] p = 0.01). Specific support for mother-child relationship should be implemented in ART-women with PPMD.

[Factors Influencing the Intention for Continual Fertility Treatments by the Women Undergoing Assisted Reproductive Technology Procedures: A Cross-Sectional Study].

PURPOSE: This cross-sectional study aimed to identify factors influencing the intention for continual fertility treatments among women undergoing assisted reproductive technology (ART). METHODS: A total of 197 women were recruited through convenience sample from fertility hospitals in Gyeonggi-do and Busan, South Korea. Data were collected using a self-report questionnaire incorporating measures of uncertainty; Depression Anxiety Stress Scales; Fatigue Severity Scale; Coping Scale for Infertility-Women; spousal support; treatment environment; and intention for continual fertility treatment. Descriptive statistics, chi-square tests, t-tests, and logistic regression analysis were conducted using IBM SPSS 26.0. RESULTS: As many as 70.6% of the participants expressed an intention for continual fertility treatments. Logistic regression analysis revealed that factors such as uncertainty (odds ratio [OR] = 0.44, 95% confidence interval [CI] 0.20~0.95), active coping (OR = 4.04, 95% CI 1.11~14.71), treatment environment (OR = 2.77, 95% CI 1.26~6.07), and the duration of marriage (OR = 2.61, 95% CI 1.24~5.49) were significantly related with this intention. CONCLUSION: These findings underscore the significance of uncertainty management, having proactive coping strategies, having supportive treatment environments, and considering the duration of marriage concerning women's intention for continual fertility treatment in the context of ART. The implications of these results extend to the development of nursing intervention programs aimed at providing crucial support for women undergoing ART and seeking to continue their infertility treatment.

Prediction of pregnancy-related complications in women undergoing assisted reproduction, using machine learning methods.

OBJECTIVE: To use machine learning methods to develop prediction models of pregnancy complications in women who conceived with assisted reproductive techniques (ART). DESIGN: A nation-wide register-based cohort study with prospectively collected data. SETTING: Swedish national registers and nationwide quality IVF register. PATIENT(S): all nulliparous women who achieved birth within the first 3 ART treatment cycles between 2008 and 2016 in Sweden. INTERVENTION(S): Characteristics before the use of ART, such as demographics and medical history, were considered potential predictors in the development of before treatment prediction models. ART treatment details were further included in after treatment prediction models. MAIN OUTCOME MEASURE(S): Potential diagnoses of preeclampsia, placental complications (previa, accreta, and abruption), and postpartum hemorrhage were identified using the International Classification of Diseases recorded in the Swedish Medical Birth and Patient registers, respectively. Multiple prediction model algorithms were performed and compared for each outcome and treatment cycle, including logistic regression, decision tree model, naïve Bayes classification, support vector machine, random forest, and gradient boosting. The performance of each model was assessed with C statistic, and nested cross-validation was used to aid model selection and hyperparameter tuning. RESULT(S): A total of 14,732 women gave birth after the first (N = 7,302), second (N = 4,688), or third (N = 2,742) ART cycle, representing birth rates of 24.1%, 23.8%, and 22.0%. Overall prediction performance did not vary much across the different methods used. In the first cycle, the before treatment prediction performance was at best 66%, 66%, and 60% for preeclampsia, placental complications, and postpartum hemorrhage, respectively. Inclusion of after treatment characteristics conferred slight improvement (approximately 1%-5%), as did prediction in later cycles (approximately 1%-5%). The top influential and consistent predictors included age, region of residence, infertility diagnosis, and type of embryo transfer (fresh or frozen) in the later (2nd and 3rd) cycles. Body mass index was a top predictor of preeclampsia and was also influential for placental complications but not for postpartum hemorrhage. CONCLUSION(S): The combined use of demographics, medical history, and ART treatment information was not enough to confidently predict serious pregnancy complications in women who conceived with ART. Future studies are needed to assess if additional longitudinal follow-up during pregnancy can improve the prediction to allow clinical protocol development.

Comparative cross-sectional study on sexual function of couples during pregnancy: Assisted reproductive techniques versus spontaneous conceptions.

This study aims to compare the sexual functions of couples undergoing assisted reproductive techniques (ART) with those conceiving spontaneously during pregnancy. A total of 102 couples participated in this cross-sectional study, with 68 couples in the spontaneous conception group and 34 couples in the ART group. Data collection was conducted face-to-face in the antenatal clinic using separate "Descriptive Information Form" for women and men, "Female Sexual Function Index (FSFI)" for women, and "Libido Scoring System (LSS)" for men. Descriptive statistical methods, Chi-square and Fisher exact tests, t-test, and Pearson correlation test were used for data analysis. It was observed that the mean FSFI total scores of women who conceived spontaneously and through ART during pregnancy were at a good level (≥30), while the mean LSS scores of their partners were at a moderate level (5-7). No statistically significant distinction existed among the groups. Further research is advisable by adjusting the sample selection criteria, such as gravida, duration of ART treatment, and gestational age.

Cette étude vise à comparer les fonctions sexuelles des couples soumis à des techniques de procréation assistée (ART) avec ceux qui conçoivent spontanément pendant la grossesse. Au total, 102 couples ont participé à cette étude transversale, dont 68 couples dans le groupe conception spontanée et 34 couples dans le groupe ART. La collecte de données a été réalisée en face-à-face dans la clinique prénatale en utilisant un « formulaire d'informations descriptives ¼ distinct pour les femmes et les hommes, un « indice de fonction sexuelle féminine (FSFI) ¼ pour les femmes et un « système de notation de la libido (LSS) ¼ pour les hommes. Des méthodes statistiques descriptives, les tests exacts du chi carré et de Fisher, le test t et le test de corrélation de Pearson ont été utilisés pour l'analyse des données. Il a été observé que les scores totaux moyens FSFI des femmes ayant conçu spontanément et par TAR pendant la grossesse étaient à un bon niveau (≥30), tandis que les scores moyens LSS de leurs partenaires étaient à un niveau modéré (5-7). Aucune distinction statistiquement significative n'existait entre les groupes. Des recherches plus approfondies sont recommandées en ajustant les critères de sélection des échantillons, tels que la gravité, la durée du traitement ART et l'âge gestationnel.

A comparison of pregnancy outcomes and congenital malformations in offspring between patients undergoing intracytoplasmic sperm injection and conventional in vitro fertilization: a retrospective cohort study.

OBJECTIVE: To explore whether intracytoplasmic sperm injection (ICSI) would increase the malformation risk in fetuses and live births compared with conventional in vitro fertilization (IVF). DESIGN: Retrospective cohort study. PATIENT(S): Data were collected from couples who underwent conventional IVF or ICSI from January 2009 to December 2019 at the Center for Reproductive Medicine of Peking University Third Hospital in the People's Republic of China. A total of 46,167 conventional IVF fresh transfer cycles and 33,247 ICSI fresh transfer cycles were included. INTERVENTION(S): Intracytoplasmic sperm injection and conventional IVF. MAIN OUTCOME MEASURE(S): The primary outcomes were congenital abnormalities in live births. The secondary outcomes included the pregnancy outcomes, the malformations among the miscarriages, specific types of malformations in live births, birth weight, and sex. RESULT(S): The rates of congenital malformations in conventional IVF and ICSI were 5.44‰ and 5.78‰, respectively. There was no statistically significant difference between the two groups, as indicated by the adjusted odds ratio of 1.098 (95% confidence interval 0.787, 1.532). The rates of specific malformations were comparable between ICSI and IVF. Additionally, no discernible disparities were noted in pregnancy outcomes, the malformations among the miscarriages,birth weight between the two groups. CONCLUSION: Our study suggested the safety of ICSI and provided novel evidence by comparing pregnancy outcomes and congenital malformations in offspring between patients undergoing conventional IVF and ICSI.

Effects of Physical Activity on Fertility Parameters: A Meta-Analysis of Randomized Controlled Trials.

PURPOSE: Augmented adiposity may negatively impact sexual sphere through its metabolic effects and its detrimental impact on reproductive hormones. Moreover, a dysregulated metabolic pathway may promote apoptosis among spermatogenic cells. Based on these premises, a relation between weights loss and ameliorate semen parameters seems beneficial. To investigate if physical activity may affect semen parameters and fertility rate, a systematic literature search on major dataset has been performed. MATERIALS AND METHODS: The search terms included: "Assisted reproduction therapies," "fertility," "semen parameters," "sperm parameters," and "physical activity." This analysis was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines and it was registered on PROSPERO (CRD42023384471). A total of 47 studies have been identified; 1 reference has been eliminated after duplication check. After preliminary screening 32 papers have been excluded. Considering the exclusion criteria, 15 full-text articles were evaluated for eligibility. After a full-text review, six studies published during a span of eight years (2014-2022) have been included in the meta-analysis. Semen parameters, pregnancy and birth rates were investigated. The revised Cochrane risk of bias tool (Rob2) has been used to check the risk of bias. RESULTS: The number of patients enrolled in studies ranges from 17 to 521; in the end, a total of 1,637 patients have been enrolled in the study. Fertility parameters investigated were semen quality parameters and pregnancy rates and live births. A statistically significant relationship between physical exercise and sperm concentration (p=0.02), total sperm motility (p<0.01), total sperm count (p<0.01), normal morphology (p<0.01) has been established. Moreover, the study registered a statistically significant association within physical activity and total pregnancy rate (p<0.01) and live birth rate (p<0.01). CONCLUSIONS: We demonstrated that physical activity is significantly associated with amelioration of semen parameters and may be crucial in improving or even reverting male infertility.

Sperm DNA Fragmentation: causes, evaluation and management in male infertility.

Male infertility is a great matter of concern as out of 15% of infertile couples in the reproductive age, about 40% are contributed by male factors alone. For DNA condensation during spermatogenesis, constrained DNA nicking is required, which if increased beyond certain level results in infertility in men. High sperm DNA Fragmentation (SDF) majorly contributes to male infertility and its association with regards to poor natural conception and assisted reproductive technology (ART) outcomes is equivocal. Apoptosis, protamination failure and the excess of reactive oxygen species (ROS) are considered to be the main causes of SDF. It's testing came into existence because of the limitations of the conventional methods in explaining infertility in normozoospermic infertile individuals. Over the past 25 years, SDF's several testing strategies have been proposed to diagnose the aetiology of infertility. Various treatments combined with sperm selection techniques are being used alone or in combination to reduce DNA fragmentation index (DFI) and obtain spermatozoa with high quality chromatin for assisted reproduction. This review summarises SDF's main causes, its impact on fertility and clinical outcomes in assisted reproduction, the need to perform test, testing procedures, and the treatment strategies.

Reproductive outcomes and reproductive health care utilization among male survivors of childhood cancer: A DCCSS-LATER study.

BACKGROUND: Treatment-related gonadal dysfunction leading to fertility problems is a frequently encountered late effect in childhood cancer survivors (CCSs). This study evaluated reproductive outcomes and reproductive health care utilization among male CCSs compared with male siblings. METHODS: A nationwide cohort study was conducted as part of the Dutch Childhood Cancer Survivor LATER study part 1, a questionnaire and linkage study. A questionnaire addressing reproductive outcomes and reproductive health care was completed by 1317 male CCSs and 407 male siblings. A total of 491 CCSs and 185 siblings had a previous or current desire for children and were included in this study. RESULTS: Fewer CCSs had biological children compared with siblings (65% vs. 88%; p < .001). The type of conception by men who fathered a child was comparable between CCSs and siblings (spontaneous conception of 90% of both groups; p = .86). The percentage of men who had consulted a reproductive specialist because of not siring a pregnancy was higher in CCSs compared with siblings (34% vs. 12%; p < .001). Following consultation, fewer CCSs underwent assisted reproductive techniques (ART) compared with siblings (41% vs. 77%; p = .001). After ART, fewer CCSs fathered a child compared with siblings (49% vs. 94%; p = .001). CONCLUSIONS: More male survivors consult a reproductive specialist, but fewer survivors undergo ART and father a child after ART compared with siblings. This insight is important for understanding potential problems faced by survivors regarding family planning and emphasizes the importance of collaboration between oncologists and reproductive specialists.

Effects of SARS-CoV-2 infection during ovarian stimulation on ART outcomes.

RESEARCH QUESTION: Does severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection during ovarian stimulation affect assisted reproductive technology outcomes? DESIGN: This retrospective cohort study conducted at the Reproductive Medicine Centre of The First Affiliated Hospital of Anhui Medical University aimed to assess the effects of acute SARS-CoV-2 infection during IVF on treatment outcomes and the reproductive system. The study included 151 treatment cycles involving couples with coronavirus disease 2019 (COVID-19) during ovarian stimulation, along with 224 cycles of non-infected couples as a control group. Clinical characteristics and laboratory parameters were analysed, including total gonadotrophin dosage, duration of ovarian stimulation, number of oocytes retrieved, fertilization method, fertilization rate, and number of blastocyst embryos available. Forty-six follicular fluid samples, 38 semen samples and 78 embryo culture medium samples from patients with COVID-19 were tested for SARS-CoV-2 RNA using reverse transcription polymerase chain reaction assay. RESULTS: The treatment and control groups showed similar cycle characteristics, including fertilization method, total gonadotrophin dosage and duration of ovarian stimulation. The mean number of oocytes retrieved per cycle and rate of mature oocytes in intracytoplasmic sperm injection cycles were comparable. No significant difference was observed in the total number of blastocyst embryos available between the groups. Furthermore, no SARS-CoV-2 RNA was detected in any of the samples of patients with COVID-19. CONCLUSIONS: In conclusion, acute SARS-CoV-2 infection during ovarian stimulation does not have a significant impact on IVF treatment outcomes. Additionally, no risk to the reproductive system was observed in patients infected with SARS-CoV-2. Therefore, individuals with asymptomatic or mild COVID-19 can safely continue IVF treatment. Future research is needed to investigate the long-term effects of COVID-19 on fertility and reproductive outcomes.

Pregnancy and assisted reproductive technology use in Australian female transfusion-dependent haemoglobinopathy patients: a 20-year retrospective analysis.

BACKGROUND: In the last few decades, the life expectancy of patients with transfusion-dependent thalassaemia (TDT) and sickle cell disease (SCD) has improved significantly, in part because of improved iron chelation. Fertility challenges and pregnancy complications have historically limited reproductive options in this group; however, improved multi-disciplinary care has made infertility a chronic disease complication requiring attention. Despite this, there are very few reports and no Australian data describing fertility and pregnancy outcomes in this population. AIMS: To identify the rate of assisted reproductive technologies (ART) utilisation in our female transfusion-dependent haemoglobinopathy patients and to establish the nature of maternal and neonatal complications in this cohort. METHODS: A 20-year retrospective analysis (1997-2017) at an Australian centre captured data on conception rates, use of assisted reproductive techniques (ART), and pregnancy and neonatal outcomes in female transfusion-dependent haemoglobinopathy patients. RESULTS: Conception was attempted in 14 women (11 TDT and three SCD) during the study period. A total of 28 pregnancies resulting in 25 live births were recorded. ART supported 13 conceptions. A positive association was not identified between elevated mean serum ferritin and ART use; however, all patients with an established diagnosis of hypogonadotropic hypogonadism (HH) required ART. Maternal complications included gestational diabetes mellitus and post-partum haemorrhage. There were no cardiac complications. Two-thirds of women underwent lower segment caesarean section, with prematurity complicating 20% of births. There were no neonatal or maternal deaths. CONCLUSION: Pregnancy is an achievable goal for women with transfusion-dependent haemoglobinopathies, although the support of ART may be required in a subset of patients.

Access to assisted human reproduction techniques in Colombia: Disparity between the recognition of reproductive rights and their effective implementation.

Public funding of assisted reproduction technologies (ARTs) is a controversial issue. Some health systems have proposed public funding of ARTs. In recent years, there has been evidence of a change in the line of jurisprudence and legislation in Colombia about this topic. This article analyzes the tension between the recognition of individual sexual and reproductive rights and the common good, in terms of the sustainability of the health system and the reasonable use of limited resources to meet the health needs of the population. This article concludes that, despite regulatory progress, there has been a lack of corresponding progress in their effective implementation and the recognition of reproductive rights.

Fertility treatment pathways and births for women with and without polycystic ovary syndrome-a retrospective population linked data study.

OBJECTIVE: To study the fertility treatment pathways used by women with and without polycystic ovary syndrome (PCOS) and which pathways were more likely to result in a birth. DESIGN: This retrospective national community-based cohort study used longitudinal self-report survey data (collected 1996-2022; aged 18-49 years) from women born in 1973-1978 who are participants in the Australian Longitudinal Study on Women's Health. The study also used linked administrative data on fertility treatments (1996-2021). PATIENTS: Of the 8,463 eligible women, 1,109 accessed fertility treatment and were included. EXPOSURE: Polycystic ovary syndrome diagnosis was self-reported. MAIN OUTCOME MEASURE: use of ovulation induction (OI), intrauterine insemination, and/or in vitro fertilization (IVF) was established through linked administrative data. Births were self-reported. RESULTS: One in 10 of the eligible participants had PCOS (783/7,987, 10%) and 1 in 4 of the women who used fertility treatment had PCOS (274/1,109, 25%). Women with PCOS were 3 years younger on average at first fertility treatment (M = 31.4 years, SD = 4.18) than women without PCOS (M = 34.2 years, SD = 4.56). Seven treatment pathways were identified and use differed by PCOS status. Women with PCOS were more likely to start with OI (71%; odds ratio [OR] 4.20, 95% confidence interval [CI]: 2.91, 6.07) than women without PCOS (36%). Of the women with PCOS who started with OI, 46% required additional types of treatment. More women without PCOS ended up in IVF (72% vs. 51%). Overall, 63% (701/1,109) had an attributed birth, and in adjusted regressions births did not vary by last type of treatment (IVF: 67%, reference; intrauterine insemination: 67%, OR 0.94 95% CI: 0.56, 1.58; OI: 61%, OR 0.71, 95% CI: 0.52, 0.98), or by PCOS status (OR 1.27, 95% CI: 0.91, 1.77). By age, 74% of women under 35 years (471/639) and 49% of women 35 years or older had a birth. CONCLUSION: More women with PCOS used fertility treatment but births were equivalent to women without PCOS. Most women followed clinical recommendations. Births did not differ between pathways, so there was no disadvantage in starting with less invasive treatments (although there may be financial or emotional disadvantages).

Predictive score for postpartum hemorrhage in vaginal deliveries following frozen embryo transfer.

Objective: To develop a predictive score for life-threatening severe postpartum hemorrhage in vaginal deliveries following frozen embryo transfer. Materials and Methods: We conducted a retrospective cohort study of 315 singleton vaginal deliveries following frozen embryo transfer from 2017 to 2022. Severe postpartum hemorrhage was defined as hemorrhage exceeding 1500 mL. A predictive score was generated from maternal characteristics and obstetric complications before delivery. We performed multivariable logistic regression analysis using 2017-2020 data and assigned points to identified risk factors. The predictive score's accuracy was evaluated using 2021-2022 data. Results: A large baby (birth weight ≥3500 g), pre-delivery maternal body mass index ≥25 kg/m2, marginal or velamentous umbilical cord insertion, and history of postpartum hemorrhage were identified as risk factors. We assigned one point to a large baby, a pre-delivery maternal body mass index ≥25 kg/m2, and marginal or velamentous umbilical cord insertion, and two points to a history of postpartum hemorrhage. The sum of the points was defined as the predictive score. The cut-off was set at two points, with a score ≥2 points being the high-risk group and a score ≤1 point being the low-risk group. The predictive score demonstrated a sensitivity of 47.8%, specificity of 85.4%, positive predictive value of 45.8%, and negative predictive value of 86.4% in the 2021-2022 validation cohort. Conclusion: The predictive score identified severe postpartum hemorrhage in approximately half of the high-risk cases. Implementing measures such as autologous blood storage may facilitate rapid response during heavy bleeding and improve maternal prognosis.
