Early and late complications of hematopoietic stem cell transplantation.

As autologous stem cell transplantation (ASCT) is increasingly frequent in some patients with multiple sclerosis (MS), the knowledge of its adverse effects is paramount. Early complications (within 30 from transplantation) are usually due to conditioning regimen and consequent neutropenia. They include infections and noninfectious complications, such as oral and intestinal mucositis, increases in liver enzymes, hemorrhagic cystitis, and worsening of neurologic symptoms. Infections in the early phase, particularly during neutropenia, are mainly of bacterial origin, such as bloodstream infections, pneumonia, central-venous catheter-related infections, urinary infections, and neutropenic typhlitis, followed by viral reactivations. Prophylaxis with acyclovir against reactivation of herpes simplex virus (HSV) and varicella-zoster virus (VZV) is recommended, while a preemptive strategy is used for cytomegalovirus (CMV) and Epstein-Barr virus (EBV) management. Fungal infections are infrequent and mainly caused by Candida, thus fluconazole prophylaxis is used in some centers. Late complications include secondary autoimmune diseases: hematologic, such as immune thrombocytopenic purpura, autoimmune hemolytic anemia, or acquired hemophilia, or nonhematologic, such as thyroiditis, rheumatoid arthritis, or Crohn's disease. Other late complications are endocrinopathies and gonadal dysfunction with possible consequences on fertility. Particularly in women over 32 years of age, the risk of infertility and premature ovarian insufficiency can be significant. Thus, reproductive counseling with fertility preservation techniques if required is mandatory before ASCT.

A Cross-Sectional Study of Mental Illnesses Among Infertile Women in Saudi Arabia.

BACKGROUND: Infertility is a global issue and carries significant mental health implications. Data on mental health among infertile women in Saudi Arabia are limited. OBJECTIVE: This study aimed to assess the prevalence and severity of depression, anxiety, and stress among infertile women in Saudi Arabia. METHODS: This analytical cross-sectional study included women of reproductive age visiting governmental hospitals in Jeddah, Saudi Arabia. The participants were asked to fill out a pre-structured questionnaire, which included the Depression, Anxiety, and Stress Scale (DASS-21) to assess their mental health status. Data analysis was conducted using IBM SPSS Statistics, Version 29.0 (released 2023, IBM Corp., Armonk, NY). The three outcome variables derived from the DASS-21 were categorized into five distinct groups for descriptive purposes. RESULTS: In this study, infertile women had significantly higher median scores for depression (18), anxiety (15), and stress (20) compared to fertile women who had median scores of 8, 8, and 10 for depression, anxiety, and stress, respectively. The differences between these two groups were statistically significant (p-value < 0.001). Furthermore, employed infertile women reported higher median scores for depression (87), anxiety (84.5), and stress (84.5) compared to unemployed women. In addition, infertile women with a monthly income of 10,001-20,000 SAR had notably higher median scores for depression (89.56), anxiety (90.22), and stress (89.94) compared to other income groups. These differences were statistically significant (p-values < 0.05). CONCLUSION: Infertility significantly contributes to mental health issues among women in Saudi Arabia. The findings highlight the need for targeted psychological interventions alongside infertility treatment to enhance the quality of life of these women.

Diagnostic value of oxidation-reduction potential for male infertility: a systematic review and meta-analysis.

Background: In the last few years, studies have initially confirmed the diagnostic significance of oxidation-reduction potential (ORP) in male infertility patients. In this article, we used meta-analysis to clarify the role of ORP in the diagnosis of male infertility. Methods: PubMed, Embase, Web of Science, and Cochrane Library were searched by computer for relevant published literature. Quality assessment of the included literature was performed by Quality Assessment of Diagnostic Accuracy Studies (QUADAS) scale. Heterogeneity analysis of included studies was conducted using Metadisc 1.4 and Stata 12.0, and effective models for quantitative synthesis were selected based on heterogeneity results; the sensitivity and specificity of the synthesis were obtained using the software, and in order to reduce the effects of heterogeneity and thresholds, the information of sensitivity and specificity was integrated. We used the subject receiver operating characteristic (SROC) curve, area under the curve (AUC) and Q* index for comprehensive evaluation. Results: Seven papers were eventually included in the study, and the results showed that ORP had a sensitivity of 0.81 [95% confidence interval (CI): 0.80-0.82] and specificity of 0.66 (95% CI: 0.63-0.69), an AUC of 0.8 and a Q* index of 0.74 for the diagnosis of male infertility. Conclusions: ORP has high sensitivity and specificity for diagnosing male infertility.

Eighteen genes primarily expressed in the testis are not required for male fertility in mice.

There are approximately 20,000 protein-coding genes in humans and mice. More than 1000 of these genes are predominantly expressed in the testis or are testis-specific and thought to play an important role in male reproduction. Through the production of gene knockout mouse models and phenotypic evaluations, many genes essential for spermatogenesis, sperm maturation, and fertilization have been discovered, greatly contributing to the elucidation of their molecular mechanisms. On the other hand, there are many cases in which single-gene knockout models do not affect fertility, indicating that tissue-specific genes are not always critical. Here, we selected 18 genes whose mRNA expression is restricted to the testis or higher than in other tissues, but whose function in male reproduction is unknown. We then created single-gene KO mouse models using the CRISPR/Cas9 system. The established KO males were subjected to mating tests and screened for effects on fecundity, revealing that these genes were not essential for spermatogenesis and male fertility. This knowledge will contribute to understanding the functions of genes characteristic of the testis and identify the cause of male infertility.

From pathophysiology to practice: addressing oxidative stress and sperm DNA fragmentation in Varicocele-affected subfertile men.

Varicocele can reduce male fertility potential through various oxidative stress mechanisms. Excessive production of reactive oxygen species may overwhelm the sperm's defenses against oxidative stress, damaging the sperm chromatin. Sperm DNA fragmentation, in the form of DNA strand breaks, is recognized as a consequence of the oxidative stress cascade and is commonly found in the ejaculates of men with varicocele and fertility issues. This paper reviews the current knowledge regarding the association between varicocele, oxidative stress, sperm DNA fragmentation, and male infertility, and examines the role of varicocele repair in alleviating oxidative-sperm DNA fragmentation in these patients. Additionally, we highlight areas for further research to address knowledge gaps relevant to clinical practice.

Feasibility of acupuncture as an adjunct intervention for ovulatory disorder infertility: A systematic review and meta-analysis.

BACKGROUND: Acupuncture (AT) is widely used in treatment of ovulatory disorder infertility (ODI), but the safety and efficacy of AT for ODI still lack an evidence-based basis. AIM: To evaluate the feasibility and effectiveness of AT as an adjunct intervention for ODI. METHODS: The Cochrane Library, Embase, PubMed, VIP, China National Knowledge Infrastructure, WanFang Data, and Chinese biomedical literature databases were searched from inception to January 20, 2024. Two reviewers independently selected studies, collected data, and evaluated methodological quality through the Cochrane Risk of Bias tool. Revman 5.4 was used for meta-analysis, and the Grade system was performed to evaluate the level of evidence for the outcomes of the meta-analysis. RESULTS: A total of 20 randomized controlled trials with 1677 ODI patients were included. Compared with the clomiphene citrate (CC) group, the AT plus CC group exhibited significant improvement of the pregnancy rate [relative risk (RR) = 1.68, 95% confidence interval (CI): 1.45-1.95, P < 0.00001, I 2 = 23%], ovulation rate (RR = 1.34, 95%CI: 1.22-1.47, P < 0.00001, I 2 = 32%), serum E2 level [mean difference (MD) = 31.36, 95%CI: 21.83-40.88, P < 0.00001, I 2 = 97%], thickness of endometrium (MD = 1.76, 95%CI: 0.71-2.81, P = 0.001, I 2 = 98%) and decreasing miscarriage rate (RR = 0.25, 95%CI: 0.09-0.65, P = 0.005, I 2 = 0%), serum follicle-stimulating hormone level (MD = -2.10, 95%CI: -3.27 to -0.94, P = 0.0004, I 2 = 99%), serum luteinizing hormone level (MD = -6.94, 95%CI: -9.89 to -4.00, P < 0.00001, I 2 = 100%), and serum progesterone level (MD = -1.66, 95%CI: -2.98 to -0.34, P = 0.01, I 2 = 96%). The AT group had a more favorable effect than CC group for improving pregnancy rate (RR = 1.52, 95%CI: 1.33-1.73, P < 0.00001, I 2 = 0%), thickness of endometrium (MD = 2.48, 95%CI: 2.15-2.81, P < 0.00001, I 2 = 0%) and reducing miscarriage rate (RR = 0.23, 95%CI: 0.13-0.44, P < 0.00001, I 2 = 0%), serum follicle-stimulating hormone level (MD = -0.55, 95%CI: -0.86 to -0.24, P = 0.0005, I 2 = 0%), and serum progesterone level (MD = -0.24, 95%CI: -0.28 to -0.20, P < 0.00001). However, the level of evidence was predominantly assessed as very low to moderate. CONCLUSION: AT can improve the pregnancy outcomes and sex hormone levels for patients with ODI. However, further studies are needed to confirm these findings.

Increase in Testosterone Levels and Improvement of Clinical Symptoms in Eugonadic men With a Prolactin-secreting Adenoma.

Objective: Testosterone concentrations, albeit rarely, may be in the normal range (>3.0 ng/mL) in men with a prolactin-secreting pituitary adenoma (PSPA-nt). The evolution of total, bioavailable testosterone, gonadotropin levels, and that of graded symptoms of testosterone deficiency (TD) are uncertain in these patients. Design: Retrospective case-control longitudinal study at a tertiary referral center. Methods: From 287 men, we selected 25 PSPA-nt men undergoing prolactin normalization (<20.0 ng/mL) during the follow-up. Graded symptoms of TD were investigated by structured interviews. Biochemical changes and TD symptoms were compared to those of a matched cohort of 61 men with pituitary neoplasms and normal testosterone levels (PA-nt). Results: Baseline testosterone levels were similar between PSPA-nt and PA-nt subjects. The prevalence of specific and suggestive symptoms of TD was higher in PSPA-nt (20% and 68%) than in PAnt (3.3 and 29.5%; P = .02 and P = .0015, respectively). At the follow-up, total and bioavailable testosterone levels increased in PSPA-nt but not in PA-nt patients (Δ change: 1.28 ± 2.1 vs0.03 ± 1.5 ng/mL, + 0.33 ± 0.55 vs-0.26 ± 0.60 ng/mL; P = .0028 and P = .0088, respectively). LH and FSH levels also increased in PSPA-nt men (P < .05). Specific and suggestive, but not nonspecific symptoms of TD, improved only in PSPA-nt men (P < .05 for both). Baseline testosterone and LH were the strongest predictors of testosterone improvement in PSPA-nt patients. Conclusion: Despite having normal testosterone levels at baseline, patients with PSPA-nt experience a relief of TD symptoms and an improvement of their pituitary-gonadal axis function following prolactin normalization, especially when baseline TT and LH levels are in the low-normal range.

No evidence of genetic causation between iron and infertility: a Mendelian randomization study.

Background: Observational studies have explored the impact of iron homeostasis on infertility; however, establishing definitive causal relationships remains challenging. This study utilized a two-sample Mendelian randomization approach to investigate the potential causal relationship between iron status and infertility. Materials and methods: Four indicators of iron status-serum iron, ferritin, transferrin saturation, and total iron binding capacity, were considered as exposure factors. Infertility was the outcome variable for both men and women. Robust causality was assessed using the primary inverse-variance-weighted method, complemented by three supplementary Mendelian randomization approaches. Sensitivity analyses were performed to enhance the precision and reliability of the results. Results: No statistically significant associations were identified between the four indicators of iron status and infertility. These results remained consistent across multiple Mendelian randomization methodologies. Conclusion: In conclusion, there is no evidence of a genetic causal relationship between iron status and infertility. Nevertheless, this does not preclude the possibility of a connection between iron status and infertility at different mechanistic levels.

The effect of Chinese herbal medicine on male factor infertility: study protocol for a randomized controlled trial.

Background: The global prevalence of infertility is 9%, with male factors potentially accounting for 40% to 60% of cases. Conventional treatments can be ineffective, invasive, costly, and linked to adverse effects and high risks. Previous studies have shown that, Chinese herbal medicine (CHM) can regulate the hypothalamus-pituitary-testis axis, improve sperm abnormalities and quality, mitigate oxidative stress, and decrease DNA fragmentation index (DFI). Yet, the evidence backing the use of Chinese herbal medicine (CHM) for treating male factor infertility lacks conviction due to study design limitations, and there remains a scarcity of studies on the live birth rate following CHM treatment for male factor infertility. Here, we describe the rationale and design of a randomized waitlist-controlled trial to evaluate the effect of CHM on the live birth rate among males with infertility. Methods: This study is a single-center, randomized, waitlist-controlled study. A total of 250 couples diagnosed with male factor infertility will be enrolled in this study and then randomly allocated into two groups in a 1:1 ratio. Male participants in CHM group (treatment group) will receive CHM once a day for 3 months. Male participants in the waitlist group (control group) will not receive any treatment for 3 months. After 3 months, participants in both groups need to be followed up for another 12 months. The primary outcome will be the live birth rate; secondary outcomes include semen quality parameters, DFI and pregnancy related outcomes. Safety will also be assessed. Discussion: The purpose of this trial is to explore the effects and safety of CHM on the live birth rate among couples dealing with male factor infertility. The outcome of this trial may provide a viable treatment option for male factor infertility. Trial registration: Chinese Clinical Trial Registry: ChiCTR2200064416.

Enhancing Endometrial Health in Assisted Reproductive Technology (ART): Evaluating Autologous Endometrial Cells and Platelets-Rich Plasma (PRP) via Hysteroscopic Injections.

This review article examines the effectiveness of incorporating autologous endometrial cells and platelet-rich plasma (PRP) through hysteroscopic injections within the field of assisted reproductive technology (ART). This study assesses the outcomes of these injections on the susceptibility of the endometrium, the dynamics of the uterus, and the frequencies of pregnancy in individuals with refractory thin endometrium. Based on a complete examination of several trials, it becomes apparent that autologous PRP injections provide encouraging turnouts in augmenting endometrial thickness, raising endometrial receptivity, and, in the end, raising chances of being pregnant and successful delivery. The research highlights the promise of autologous PRP and minimally changed endometrial cellular treatments in enhancing outcomes in ART, especially for people who have had problems with implantation. This article gives a whole evaluation of the medical use of and upgrades regarding the utilization of infusions of PRP and autologous endometrial cells under hysteroscopic control to deal with infertility issues related to endometrial health through the synthesis of contemporary studies.

Lipids, lipid-modified drug target genes, and the risk of male infertility: a Mendelian randomization study.

Background: Previous observational studies have reported a possible association between circulating lipids and lipid-lowering drugs and male infertility (MIF), as well as the mediating role of circulating vitamin D. Then, due to issues such as bias, reverse causality, and residual confounding, inferring causal relationships from these studies may be challenging. Therefore, this study aims to explore the effects of circulating lipids and lipid-lowering drugs on MIF through Mendelian randomization (MR) analysis and evaluate the mediating role of vitamin D. Method: Genetic variations related to lipid traits and the lipid-lowering effect of lipid modification targets are extracted from the Global Alliance for Lipid Genetics Genome-Wide Association Study. The summary statistics for MIF are from the FinnGen 9th edition. Using quantitative expression feature loci data from relevant organizations to obtain genetic variations related to gene expression level, further to explore the relationship between these target gene expression levels and MIF risk. Two-step MR analysis is used to explore the mediating role of vitamin D. Multiple sensitivity analysis methods (co-localization analysis, Egger intercept test, Cochrane's Q test, pleiotropy residuals and outliers (MR-PRESSO), and the leave-one-out method) are used to demonstrate the reliability of our results. Result: In our study, we observed that lipid modification of four lipid-lowering drug targets was associated with MIF risk, the LDLR activator (equivalent to a 1-SD decrease in LDL-C) (OR=1.94, 95% CI 1.14-3.28, FDR=0.040), LPL activator (equivalent to a 1-SD decrease in TG) (OR=1.86, 95% CI 1.25-2.76, FDR=0.022), and CETP inhibitor (equivalent to a 1-SD increase in HDL-C) (OR=1.28, 95% CI 1.07-1.53, FDR=0.035) were associated with a higher risk of MIF. The HMGCR inhibitor (equivalent to a 1-SD decrease in LDL-C) was associated with a lower risk of MIF (OR=0.38, 95% CI 0.17-0.83, FDR=0.39). Lipid-modifying effects of three targets were partially mediated by serum vitamin D levels. Mediation was 0.035 (LDLR activator), 0.012 (LPL activator), and 0.030 (CETP inhibitor), with mediation ratios of 5.34% (LDLR activator), 1.94% (LPL activator), and 12.2% (CETP inhibitor), respectively. In addition, there was no evidence that lipid properties and lipid modification effects of six other lipid-lowering drug targets were associated with MIF risk. Multiple sensitivity analysis methods revealed insignificant evidence of bias arising from pleiotropy or genetic confounding. Conclusion: This study did not support lipid traits (LDL-C, HDL-C, TG, Apo-A1, and Apo-B) as pathogenic risk factors for MIF. It emphasized that LPL, LDLR, CETP, and HMGCR were promising drug targets for improving male fertility.

If CE affects infertile women's outcomes after surgery?

OBJECTIVE: To investigate the prevalence of chronic endometritis (CE) in infertile patients and whether it affects spontaneous pregnancy after reproductive surgery in infertile patients. MATERIALS AND METHODS: In this study, we collected clinical information on infertility patients who underwent reproductive surgery at the Reproductive Medicine Centre of the Second Hospital of Lanzhou University from 2021.1 to 2022.8. All patients underwent laparoscopic and hysteroscopic surgery. Tubal lubrication was performed concurrently with endometrial sample collection and pathological examination. The specimens were immunohistochemically stained with CD38 and CD138, and those who tested positive at the same time were diagnosed with chronic endometritis. As of 2023.9, the patients were followed up by telephone to determine whether chronic endometritis impacted postoperative pregnancy. OUTCOME: A total of 81 patients were finally included in the study. Of these, 25 were in the chronic endometritis group, and 56 were in the non-chronic endometritis group. There were no appreciable differences between the two groups' demographic statistics. Furthermore, neither the bilateral appendages nor the uterus's intraoperative conditions showed a statistically significant difference. Patients in the chronic endometritis group had a longer time to conception from the time of surgery (7 (6.00-11.75) vs. 10 (6.50-16.00), p = 0.467) and a lower rate of spontaneous pregnancies (8/25 = 32.00 % vs. 28/55 = 50.00 %, p = 0.132) than patients with non-chronic endometritis. Among the patients who had successful spontaneous pregnancies after surgery, approximately 77.14 % had live births and 22.86 % had miscarriages, and the live birth rate between the two groups was not significantly different. (21/28 = 75.00 % vs 7/8 = 87.50 %, p = 0.651) CONCLUSION: Chronic endometritis affects approximately 31.82% of infertile patients, and following reproductive surgery, it has no discernible impact on spontaneous pregnancy.

Unraveling the molecular pathogenesis of Type 2 Diabetes and its impact on female infertility: A bioinformatics and systems biology approach.

Type 2 diabetes mellitus (T2D) has been linked with female infertility (FI). Nevertheless, our understanding of the molecular hallmarks and underlying mechanisms remains elusive. This research article aimed to find the hub genes, pathways, transcription factors, and miRNA involved. For this study, softwares like cytoscape, string, Enrichr, FFL loop, etc., were utilized. This research article employed differentially expressed genes (DEGs) to identify multiple biological targets to understand the association between T2D and female infertility (FI). Between T2D and FI, we found 3869 differentially expressed genes. We have also analyzed different pathways like thyroid hormone signaling pathways, AGE-RAGE signaling pathways in diabetic complications and ubiquitin-mediated proteolysis through pathway analysis. Moreover, hub genes MED17, PRKCG, THRA, FOXO1, NCOA2, PLCG2, COL1A1, CXCL8, PRPF19, ANAPC5, UBE2I, XIAP and KEAP1 have been identified. Additionally, these hub genes were subjected to identify the miRNA-mRNA regulation network specific to T2D-associated female infertility. In the FFL study (Feed Forward Loop), transcription factor (SP1, NFKB1, RELA and FOX01), miRNA (has-mir-7-5p, has-let-7a-5p, hsa-mir-16-5p, hsa-mir-155-5p, has-mir-122-5p, has-let-7b-5p, has-mir-124-3p, has-mir-34a-5p, has-mir-130a-3p, has-let-7i-5p, and hsa-mir-27a-3p) and six genes (XIAP, THRA, NCOA2, MED17, FOXO1, and COL1A1) among the thirteen key genes were recognized as regulator and inhibitor. Our analysis reveals that these genes can serve as a significant biomarker for female infertility linked with Type 2 Diabetes, through the prioritization of candidate genes. This study gives us insight into the molecular and cellular mechanism of T2D-associated FI. This finding helps in developing novel therapeutic approaches and will improve efficacy and reduce side effects of the treatment. This research requires further experimental investigation of the principal targets.

Seroprevalence of canid alphaherpesvirus-1 and associated risk factors in domestic dogs in North Queensland, Australia.

Canid alphaherpesvirus-1 (CaHV-1) may cause a highly fatal haemorrhagic disease in neonatal pups and is associated with reproductive, respiratory and ocular disease in older dogs. Although assumed to have a world-wide distribution, there have been few reports of CaHV-1 in Australia. The aim of this study was to investigate the seroprevalence of CaHV-1 in household dogs in a residential suburb in Townsville, as well as in dogs attending two dog shows in the region. Study participants were recruited through door-to-door non-probability sampling (Douglas dogs, n = 185) or invited to participate (Show dogs; n = 76). Dog owners completed a questionnaire that investigated possible risk factors for recent exposure to CaHV-1. A serum sample from each dog was assayed for anti-CaHV-1 antibodies using a commercially available ELISA. Associations between seropositive dogs and owner-reported risk factors were analysed using univariable analysis and multivariable logistic regression models. The seroprevalence of CaHV-1 was 11.4 % (95 % CI 6.8-15.9 %) and 17.1 % (95 % CI 5.5-28.8) for the Douglas and Show dogs, respectively, with a pooled seroprevalence of 13 % (95 % CI 8.3-17.7 %). Dogs that had suffered from conjunctivitis within the previous 3 months or were involved in breeding were more likely to be seropositive to CaHV-1. No other significant risk factors were identified. In conclusion, CaHV-1 is circulating in dogs in North Queensland and may be contributing to foetal and neonatal losses in this region.

Usefulness of mindfulness for the management of anxiety, stress, and quality of life in infertile women. A clinical exploratory study.

BACKGROUND: Infertility increases stress and affects life quality. Mindfulness reduces stress and improves life quality, but its role in infertility remains unclear. OBJECTIVE: To evaluate the effect of mindfulness on stress and quality of life of women with infertility. MATERIAL AND METHODS: An exploratory clinical study was conducted in women under infertility treatment, together with an 8-week mindfulness intervention (MND) or only infertility treatment (CTRL). Anxiety and quality of life were assessed at baseline and at the end of intervention with IDARE and FertiQoL questionnaires respectively, as well as salivary alpha-amylase and cortisol concentrations. Non-parametric statistics was used for analysis using an alpha value of 0.10. RESULTS: 14 MND and 15 CTRL completed follow-up. At baseline, CTRL patients exhibited better quality of life than MND; anxiety scores correlated negatively with quality of life. At the end of intervention, cortisol concentrations (p = 0.097), and the increments of amylase (p = 0.039), were higher in CTRL than in MND. Increases in quality of life were associated with basal anxiety score (p = 0.002), improvements in tolerability (p < 0.001), and mindfulness intervention (p = 0.014). CONCLUSION: Our results suggest that mindfulness reduces stress and improves quality of life in women under infertility treatment.

ANTECEDENTES: La infertilidad incrementa el estrés y afecta la calidad de vida. OBJETIVO: Evaluar el efecto de mindfulness (atención plena) sobre la ansiedad, estrés y calidad de vida de mujeres infértiles. MATERIAL Y MÉTODOS: Estudio exploratorio en pacientes tratadas por infertilidad más una intervención de ocho semanas con mindfulness (grupo MND) o solo tratamiento de la infertilidad (grupo de control). Al inicio y después de ocho semanas se evaluaron la ansiedad (Inventario de Ansiedad Rasgo-Estado), la calidad de vida (FertiQoL), y las concentraciones salivales de α-amilasa y cortisol. Se utilizó estadística no paramétrica, con α = 0.10. RESULTADOS: 14 mujeres del grupo MND y 15 del grupo de control completaron el seguimiento. Al inicio, las pacientes del grupo de control mostraron mejor calidad de vida; las puntuaciones de ansiedad correlacionaron negativamente con la calidad de vida. Al final, el incremento de cortisol (p = 0.097) y amilasa (p = 0.039) fueron mayores en el grupo de control. Los incrementos en la calidad de vida se asociaron a ansiedad basal (p = 0.002), incremento en la subescala tolerabilidad (p < 0.001) y mindfulness (p = 0.014). CONCLUSIÓN: Los resultados sugieren que mindfulness disminuye el estrés y mejora la calidad de vida de pacientes bajo tratamiento de la infertilidad.

Effect of astaxanthin supplementation on female fertility and reproductive outcomes: a systematic review and meta-analysis of clinical and animal studies.

CONTEXT: Oxidative stress (OS) plays a harmful role in female reproduction and fertility. Several studies explored various dietary interventions and antioxidant supplements, such as astaxanthin (AST), to mitigate the adverse effects of OS on female fertility. Ameliorative effects of AST on female fertility and the redox status of reproductive organs have been shown in several animal and clinical studies. OBJECTIVES: The main objective of present systematic review and meta-analysis of both animal and clinical studies was to provide a comprehensive overview of the current evidence on the effects of AST on female fertility and reproductive outcomes. The effect of AST on redox status, inflammatory and apoptotic markers in reproductive organs were included as the secondary outcomes. DATA SOURCES: We systematically searched electronic databases including PubMed, Scopus, and Web of Science, until January 1, 2024, using specified search terms related to AST, female reproductive performance, and infertility, considering the diverse synonyms found in the literature for interventional studies that compared oral AST supplementation with placebo or control in human or animal models. DATA EXTRACTION: Two independent reviewers extracted data on study characteristics, outcomes, and risk of bias. We pooled the results using random-effects models and assessed the heterogeneity and quality of evidence. We descriptively reported the data from animal models, as meta-analysis was not possible. DATA ANALYSIS: The meta-analysis of clinical trials showed that AST significantly increased the oocyte maturation rate (MD: 8.40, 95% CI: 4.57 to 12.23, I2: 0%) and the total antioxidant capacity levels in the follicular fluid (MD: 0.04, 95% CI: 0.02 to 0.06, I2: 0%). The other ART and pregnancy outcomes and redox status markers did not show statistically significant changes. The animal studies reported ameliorative effects of AST on redox status, inflammation, apoptosis, and ovarian tissue histomorphology. CONCLUSION: This systematic review shows that AST supplementation may improve assisted reproductive technology outcomes by enhancing oocyte quality and reducing OS in the reproductive organs. However, the evidence is limited by the heterogeneity, risk of bias, and small sample size of the included studies.

Comparison of the effect of dydrogesterone and natural micronized progesterone for luteal-phase support in assisted reproductive technology cycles: A single-blind randomized clinical trial study.

Background and Aims: One of the causes of preterm labor and recurrent abortion is progesterone deficiency in the luteal phase. The aim of the study was a comparison of the effect of oral dydrogesterone and vaginal progesterone for luteal-phase support (LPS) in assisted reproductive technology cycles (ART). Methods: This randomized clinical control trial study was conducted on 207 infertile women. Samples were randomly divided into two groups. The first group received a natural micronized vaginal progesterone (MVP) of 400 mg once daily and the second group received dydrogesterone (Duphestone) 20 mg twice daily. Then chemical pregnancy, abortion, and live births were compared in two groups. Results: The results of the study showed that the vaginal form of the drug could increase the chance of pregnancy (positive ß-human chorionic gonadotropin) versus the oral form. According to the results of multiple logistic regression analysis after adjusting for other variables, the live birth rate in the vaginal group was more than five times that of the oral group (odds ratio = 5.07; 95% confidence interval = 1.24-20.65; p = 0.023). Conclusion: The vaginal form of the progesterone could increase the chance of pregnancy and the outcome of fertility (live birth). Thus, vaginal progesterone is effective for LPS in women undergoing fresh embryo transfer.

The effects of testicular stromal stem cells on surgically injured testicular tissue in rats.

This study investigated the effects of transplanted testicular stromal stem cells (tSSCs) on surgically damaged testis tissue. Ten-week-old male Wistar albino rats were divided into three groups: control (n = 6), damage (DG) (n = 6) and testicular stromal stem cell (TSSC) (n = 6) groups. Surgically induced damage was inflicted on the left testes of both the DG and TSSC groups, with no intervention on the right testes. In the TSSC group, damaged testes were treated with transplanted tSSCs, followed by orchiectomy after 15 days. Testes tissues were stained with haematoxylin-eosin (H&E), and recovery rates of functional structures were assessed by modified Johnsen scoring. The effects of tSSCs on testicular tissue were demonstrated by immunohistochemistry using BAX, BCL-2 and caspase 3. Serum testosterone levels were analysed using the enzyme-linked immunosorbent assay (ELISA) method. Surgical damage caused germ cell degeneration in some seminiferous tubules and a decrease in interstitial areas. With tSSC treatment, improvements in testicular architecture were identified through spermatogenesis in the seminiferous tubules and normal histological structures in the interstitial areas. Correspondingly, in the modified Johnsen score, the DG group showed a significant difference compared to the other groups (p = 0.001). High expressions of BAX, BCL-2 and caspase-3 in the DG group revealed prominent features of apoptosis. With the injection of tSSCs, these expressions significantly normalized according to H score analysis (all p = 0.004). Although serum testosterone levels in the tSSC group were higher compared to the control and DG groups, this difference was not statistically significant (p = 0.119). This study suggests transplanting tSSCs could accelerate tissue healing after testicular sperm extraction (TESE) surgery for azoospermia patients, potentially paving the way for a new and important clinical treatment.

Is Hysteroscopic Metroplasty Advisable for U2bC2V1 Malformation?

A complete uterine septum, with a double cervix and vaginal septum, is a complex and rare congenital genital tract anomaly. The diagnosis is difficult and often challenging, requiring complex imaging investigations and diagnostic hysteroscopy. The benefit of hysteroscopic metroplasty for this uterine malformation is still the subject of dispute. However, the potential benefits of obtaining pregnancies and reducing the rate of abortions make this surgical method a desirable one. We present a series of three cases with U2bC2V1 malformation that were diagnosed via magnetic resonance imaging (MRI), in which hysteroscopic removal of the uterine septum and resection of the longitudinal vaginal septum were performed, with the preservation of the two cervixes. All patients became pregnant after the hysteroscopic intervention and reported an improvement in dyspareunia and dysmenorrhea.

Utility of culture and molecular methods using AllplexTM Bacterial Vaginosis Plus Assay (SeegeneⓇ) as a tool for endometriosis, infertility and recurrent pregnancy loss diagnosis.

Endometriosis, infertility, or recurrent pregnancy loss (RPL) are entities characterised by a decrease in Lactobacillus spp. and an increase in bacterial vaginosis-associated bacteria, (BVAV) according with 16S rRNA sequencing studies. However, the use of nucleic acid amplification tests (NAAT) as a tool for diagnosis algorithms is unknown. Seventy-four patients were included, with a median age of 36.5 years old (IQR: 34-39) including infertility (n=31), endometriosis (n=25), or RPL (n=18), for culturing and NAAT using the Allplex™ Bacterial Vaginosis Plus (ABVP) assay (SeegeneⓇ) with endometrial samples. The objective was determining the utility of ABVP assay for diagnosing the entities. Forty-six microorganisms were isolated from 31 out of 74 patients (41.9 %). Twenty-five endometrial samples (33.8 %) were positive for some targets included in the ABVP-assay, with median Ct value ∼37 (IQR: 31.3-37.1) and Qt value 1.43 Log10copies/reaction (IQR:1.1-2.6). For Lactobacillus species, sensitivity and specificity were 80 % and 84 %, respectively. Gardnerella vaginalis, 63.6 % and 95.7 %. No significant increase in BVAV was detected in any of the gynaecological entities. The ABVP and culture based algorithm did not show utility as a tool for endometriosis, infertility, or RPL diagnosis.
