Abstract
Objective To investigate the association between cesarean section (CS) and postpartum fertility and dysmenorrhea using data from a Japanese insurance registry. Methods This retrospective cohort study used a data set of patients registered between 2007 and 2021 in an insurance registry comprising specific employee-based health insurance companies in Japan. Of those data sets, we included data from participants who had their first recorded childbirth between 2014 and 2018. The exclusion criteria were any prior deliveries, dysmenorrhea, or complications that would affect the next pregnancy or postpartum dysmenorrhea since 2007. The occurrence of subsequent childbirth and postpartum dysmenorrhea until 2021 was compared between the CS and vaginal delivery (VD) groups using the log-rank test and Cox proportional hazards model with stratification according to age and age matching. Results This study included 25,984 (5,926 after age matching) and 5,926 participants in the VD and CS groups, respectively. After age matching, the rate of subsequent childbirth was 18.3% and 16.3%, and the rate of postpartum dysmenorrhea was 6.5% and 7.8% in the VD and CS groups, respectively. There were fewer subsequent childbirths in the CS group than in the VD group after age matching in the stratified Cox proportional hazards model (hazard ratio [HR] 95% confidence interval [CI]: 0.86 [0.79-0.94]). The CS group had a significantly higher risk of dysmenorrhea (HR [95% CI]: 1.18 [1.03-1.36]). Conclusions Although confounding might be existing, our study suggests that CS might be associated with decreased postpartum fertility and increased dysmenorrhea. The medical indications for CS should be carefully determined; post-CS women should be meticulously followed up.

Abstract
Endometrial calcification is an uncommon clinical entity. They can be detected during pelvic ultrasonography or as incidental pathologic findings. Most of the cases are asymptomatic or present with secondary infertility and menstrual anomalies. Its definite etiology is still not known and the pathogenesis is uncertain; its clinical importance is not yet fully validated. Since there is no exact simulating disease to compare this condition in Ayurveda; according to the features involved in its pathophysiology; involvement of Tridosha has been contemplated. Therefore, the management of endometrial calcifications is conducted by considering the specific Dosha involved. Uttara Basti is a minimally invasive procedure that can be easily performed as an outpatient procedure, offering a more convenient and cost-effective approach to enhance the treatment of endometrial calcifications. Here in this case study, the patient had been diagnosed with endometrial calcifications and was subsequently scheduled for an Ayurvedic management protocol. The procedure of Uttara Basti with Kshara Oil and Phala ghrita, was undertaken for a duration of 3 consecutive months, following the cessation of menstrual flow. The patient experienced improvment in scanty menses, her USG showed a reduction in endometrial calcification. Furthermore, she was conceived.

Abstract
INTRODUCTION We conducted a scoping review to analyze the effects and implications of vitamin D deficiency on female reproductive health during the last decade, considering temperate planetary zones and climate change impacts. METHODS We used a qualitative methodology for a panoramic database review of PubMed, Web of Science, and Scopus covering articles from the last decade focused on populations living at latitudes higher than 40° N and 40° S. As descriptors, we used the phrases climate change, cholecalciferol or vitamin d3, pregnancy, and woman health and the Boolean operators AND and OR. We excluded letters to the editor, reviews, protocols, and clinical trials without human participants, as well as duplicate articles. RESULTS We included 35 studies in English, the majority of which were from North America or Europe. No studies were found from the Southern Hemisphere or having any direct relation with climate change, although studies demonstrated that latitude and environmental factors affected vitamin D deficiency, which had an impact on pregnant women and their children. Supplementation guidelines were not well developed, and there was a lack of studies among at-risk groups of women (eg, darker skin, higher latitudes, immigrants) across the life span. DISCUSSION Vitamin D deficiency is a global environmental problem that affects female reproductive health and depends on multiple environmental factors and human behavior. Therefore, we recommend consideration of environmental and sociocultural factors in public policy and clinical research and more research on the effectiveness of supplementation and fortification strategies. Health care professionals working in reproductive health need to generate actions for detection of, education on, and prevention of vitamin D deficiency among women across their life spans, considering the multicausality of the phenomenon, which includes environmental and climate factors in population health.

Abstract
Sperm detection performance is particularly critical for sperm motility tracking. However, there are a large number of non-sperm objects, sperm occlusion and poorly detailed texture features in semen images, which directly affect the accuracy of sperm detection. To solve the problem of false detection and missed detection in sperm detection, a multi-sperm target detection model, Yolov5s-SA, with an SA attention mechanism is proposed based on the YOLOv5s algorithm. Firstly, a depthwise, separable convolution structure is used to replace the partial convolution of the backbone network, which can ensure stable precision and reduce the number of model parameters. Secondly, a new multi-scale feature fusion module is designed to enhance the perception of feature information to supplement the positional information and high-resolution of the deep feature map. Finally, the SA attention mechanism is integrated into the neck network before the output of the feature map to enhance the correlation between the feature map channels and improve the fine-grained feature fusion ability of YOLOv5s. Experimental results show that compared with various YOLO algorithms, the proposed algorithm improves the detection accuracy and speed to a certain extent. Compared with the YOLOv3, YOLOv3-spp, YOLOv5s and YOLOv5m models, the average accuracy increases by 18.1%, 15.2%, 6.9% and 1.9%, respectively. It can effectively reduce the missed detection of occluded sperm and achieve lightweight and efficient multi-sperm target detection.

Serum interleukin-38 and -41 levels as candidate biomarkers in male infertility. Immunol Lett 2023; 255:47-53. [PMID: 36870420 DOI: 10.1016/j.imlet.2023.02.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 02/25/2023] [Accepted: 02/26/2023] [Indexed: 03/06/2023]
Abstract
BACKGROUND Interleukin (IL)-38 and IL-41 are novel cytokines, but their role in male infertility (MI) is unknown. The purpose of this study was to measure the levels of serum IL-38 and IL-41 in patients with MI and correlate these levels with semen indexes. METHODS Eighty-two patients with MI and 45 healthy controls (HC) were recruited for this study. Semen parameters were detected using computer-aided sperm analysis, Papanicolaou staining, ELISA, flow cytometry, peroxidase staining and enzyme methods. Serum IL-38 and IL-41 levels were determined by ELISA. RESULTS Serum IL-38 levels were decreased (P < 0.01) in patients with MI compared with HC. Serum IL-41 levels were significantly higher in patients with MI than in HC (P < 0.0001). In patients with MI, serum IL-38 levels were positively correlated with semen white blood cell counts (r = 0.29, P = 0.009), and there was a positive correlation between semen white blood cell counts and sperm concentration (r = 0.28, P = 0.0100) and seminal plasma elastase (r = 0.67, P < 0.0001). Receiver operating characteristic curve analysis showed that the area under the curve of IL-38 for diagnosing MI was 0.5637 (P > 0.05), and the area under the curve of IL-41 for diagnosing MI was 0.7646 (P < 0.0001). CONCLUSIONS Serum IL-38 levels were significantly lower, and serum IL-41 levels were higher in patients with MI. These results suggest that IL-38 and IL-41 may be novel biomarkers for the diagnosis of MI.

Abstract
Objective: Semen analysis is performed as one of the screening tests for infertility, including motility, morphology, and concentration observation. We aimed to investigate the expression rates of tumor necrosis factor-α (TNF-α) and heat shock protein (HSP)-70 as two opposite affectors of apoptosis in men with normal semen parameters and abnormal parameters to find the possible effect of this pathway on sperm parameters. We also aimed to investigate the apoptotic markers (DNA fragmentation and Caspase-3 expression) to observe the correlation of this pathway with apoptosis. Materials and Methods: A total of 32 men who applied for infertility evaluation were included in the study. Semen analysis was performed according to WHO criteria. Liquefaction time, appearance, volume, pH, viscosity, sperm concentration, total motility rate, sperm motility, and percentage of spermatozoa with normal morphology were determined. TNF-α, HSP-70, and Caspase-3 immunolocalization were scored histologically. A sperm chromatin dispersion test was used to observe DNA fragmentation. Results: There was no significant difference in TNF-α protein expression rate (mild level). The HSP-70 expression rate was lower, especially in the head region of normo. Caspase-3 was higher totally in non-normo. DNA fragmentation levels were similar in both the groups. Conclusion: From TNF-α protein expression at the mild level in both the groups, it may be hypothesized that the apoptotic pathway might not be triggered by the extrinsic pathway. We found a negative correlation between HSP-70 and Caspase-3 expressions, providing further evidence that HSP-70 works as an inhibitor to apoptosis. This, particularly on specific points, made us think the communication might begin in the anterior chamber, then flow through the cell body to the tail. HSP-70 expression was lower in normo than in non-normo, indicating the possible role of HSP-70 as an answer to any type of stressor in non-normozoospermic patients. Correspondingly, it may be concluded that HSP has an antiapoptotic effect, causing inhibition in the elimination of abnormal sperm cells impairing sperm parameters.

Abstract
INTRODUCTION Complement factors mediate the recruitment and activation of immune cells and are associated with metabolic changes during pregnancy. The aim of this study was to determine whether complement factors in the maternal serum and follicular fluid (FF) are associated with in vitro fertilization (IVF) outcomes in overweight/obese women. METHODS Forty overweight/obese (BMI = 30.8 ± 5.2 kg/m2) female patients, 33.6 ± 6.3 years old, undergoing IVF treatment for unexplained infertility were recruited. Baseline demographic information, including biochemical hormonal, metabolic, and inflammatory markers, and pregnancy outcome, was collected. Levels of 14 complement markers (C2, C4b, C5, C5a, C9, adipsin, mannose-binding lectin, C1q, C3, C3b/iC3b, C4, factor B, factor H, and properdin) were assessed in the serum and FF and compared to IVF outcome, inflammatory, and metabolic markers using multivariate and univariate models. RESULTS Out of 40 IVF cycles, 14 (35%) resulted in pregnancy. Compared to women with failed pregnancies, women with successful pregnancies had higher levels of adipsin in the serum and FF (p = 0.01) but lower C5a levels (p = 0.05). Serum adipsin levels were positively correlated with circulating levels of vitamin D (R = 0.5, p = 0.02), glucagon (R = 0.4, p = 0.03), leptin (R = 0.4, p = 0.01), resistin (R = 0.4, p = 0.02), and visfatin (R = 0.4, p = 0.02), but negatively correlated with total protein (R = -0.5, p = 0.03). Higher numbers of top-quality embryos were associated with increased levels of C3, properdin, C1q, factors H and B, C4, and adipsin, but with reduced C2 and C5a levels (p ≤ 0.01). CONCLUSIONS Higher adipsin and lower C5a levels in the maternal serum during implantation are potential markers of successful outcome in obese women undergoing IVF-assisted pregnancies.

Abstract
Infertility is a global health problem affecting 10-15% of couples in reproductive age. Recent studies have provided growing evidence supporting that lifestyle factors can affect male fertility through alterations in endocrine profiles, spermatogenesis and/or sperm function. One of these critical factors could be the change in the food intake behavior in modern societies that produces metabolic alterations. Regarding this, metabolic syndrome (MetS) prevalence has increased in epidemic in the last 40-50 years. Although MetS is associated with advanced age, changes in lifestyles have accelerated the appearance of symptoms in the reproductive age. We review herein the current understanding of the relationship between MetS and the male reproductive status. For this purpose, in this narrative review a comprehensive literature search was made in both animal models and men, allowing us to evaluate such relationship. This analysis showed a high variability in the reproductive phenotypes observed in patients and mice suffering MetS, including sperm parameters, fertility and offspring health. In view of this, we proposed that the reproductive effects, which are diverse and not robust, observed among MetS-affected males, might depend on additional factors not associated with the metabolic condition and contributed not only by the affected male but also by his partner. With this perspective, this review provides a more accurate insight of this syndrome critical for the identification of specific diagnostic indicators and treatment of MetS-induced fertility disorders.

Abstract
Recurrent pregnancy loss (RPL) is one of the most complex and challenging scenarios in reproductive medicine. New theories about the mechanisms behind RPL have recently emerged, highlighting the multifactorial nature of this serious pregnancy complication. Unfortunately, these preclinical observations are rarely validated in the human scenario, where treatment remains ineffective and empirical. New technologies such as organoids, organ-on-a-chip, and 3D printing can be used to characterize the molecular cross talk between the uterine environment with its unique inflammatory cells and the developing embryo. Understanding the mechanisms behind RPL and identifying mediators and effectors and validating these targets for prevention and therapy in humans will have a profound impact on women's health.

Abstract
Infertility is a condition whereby pregnancy does not occur despite having unprotected sexual intercourse for at least one year. The main reason could originate from either the male or the female, and sometimes, both contribute to the fertility disorder. For the male, sperm disorder was found to be the most common reason for infertility. In this paper, we proposed male infertility analysis based on automated sperm motility tracking. The proposed method worked in multistages, where the first stage focused on the sperm detection process using an improved Gaussian Mixture Model. A new optimization protocol was proposed to accurately detect the motile sperms prior to the sperm tracking process. Since the optimization protocol was imposed in the proposed system, the sperm tracking and velocity estimation processes are improved. The proposed method attained the highest average accuracy, sensitivity, and specificity of 92.3%, 96.3%, and 72.4%, respectively, when tested on 10 different samples. Our proposed method depicted better sperm detection quality when qualitatively observed as compared to other state-of-the-art techniques.
