Risk factors underlining reproductive performance in smallholder beef cattle herds of South Africa.

Improving the historically low reproductive performance of beef cattle in smallholder systems is essential for its productivity and profitability. Therefore, identifying and addressing risk factors associated with low performance in this system present an opportunity for improvement. The study aimed to evaluate the effect of animal and management risk factors on pregnancy rate (PR), fetal and calf loss (FC), calving interval (CI) and days open (DO) in smallholder beef cattle farms. A multi-stage selection approach was conducted in five provinces of South Africa. Cow records (3694) collected from 40 smallholder herds over two years (2018-2019) were analysed. Data on animal and herd management factors including body condition score (BCS), cow age class, breed type, lactation status, culling old/non-productive cows, record-keeping, and breeding and calving seasons were recorded. The GLIMMIX procedure was computed to determine risk factors associated with performance indicators (PR, FC, CI and DO). Risk factors highly associated with performance were breed type, BCS, cow-age class and breeding/calving season (P ≤ 0.05). Indicators FC, DO and CI increased with decreased BCS, autumn calving seasons, and in first calvers and aged cows. Whereas, PR increased with increasing odds of BCS and breeding seasons between December-March, November-February and January-March. Optimizing reproductive performance in smallholder beef cattle herds may involve managing cow body condition, breeding with adapted genotypes and synchronizing breeding with favourable seasons. Therefore, record keeping and regular monitoring of herd nutrition, climate and breed performance may be significant in improving reproductive performance in smallholder herds.

Sex differences in DNA methylation variations according to ART conception-evidence from the Norwegian mother, father, and child cohort study.

Previous studies have shown cord-blood DNA methylation differences in newborns conceived using assisted reproductive technologies (ART) compared to those conceived naturally. However, whether these ART-related DNA methylation differences vary with children's sex is unknown. We hypothesize that the DNA methylation differences in cord blood between ART-conceived and naturally conceived newborns also varies by the sex of the child, with distinct patterns of differential methylation present in males and females. We investigated sex differences in cord-blood DNA methylation variation according to conception by ART using the Illumina MethylationEPIC platform, comparing 456 ART-conceived versus 507 naturally-conceived girls, and 503 ART-conceived and 473 naturally-conceived boys. We identified 37 differentially methylated CpGs according to ART-conception among girls, and 70 differentially methylated CpGs according to ART-conception among boys, when we used a 1% false discovery rate to account for multiple testing. Ten CpGs were differentially methylated according to conception by ART in both sexes. Among the genes that were associated with these CpGs, we found the BRCA1; NBR2 gene (two CpGs) was hypermethylated in girls while the APC2 (two CpGs) and NECAB3;ACTL10, (four CpGs) related to cellular signaling were hypomethylated in boys. These findings confirm the presence of sex-specific epigenetic differences, illustrating the nuanced impact of ART on the fetal epigenome. There is a need for further explorations into the implications for sex-specific developmental trajectories and health outcomes in ART-conceived children.

Comparative Characteristic of the Methods of Isolation of Oocytes and Spermatozoa in Laboratory Animals (Review).

Over the past decade, there has been an increasing trend in the use of assisted reproductive technologies, which have significantly expanded the opportunities to overcome the problem of infertility. However, the problem of increasing the effectiveness of in vitro fertilization remains open. Isolation of germ cells from animals is a necessary process for various experimental studies. Animal germ cells can be used in experiments to study physical, chemical, genetic, immunological, and microbiological factors affecting reproduction efficiency and for the development of techniques that increase the effectiveness of in vitro fertilization. All of the above determines the relevance of studying existing methods of oocyte and sperm isolation for experimental in vitro studies. Here we discuss the existing methods of sperm and oocyte isolation from animals and their advantages and disadvantages, and also substantiate priority methods for use.

Searching for effective strategies to reach boys and young men; a mixed-methods study protocol for youth clinics in Sweden.

BACKGROUND: Efforts to engage boys and young men in sexual and reproductive health (SRH) services in Sweden remain limited, with only a small proportion accessing youth clinics, the primary providers of such services. Existing initiatives are often ad-hoc and lack institutionalization within public policy and practice. This study aims to identify feasible and effective interventions to improve boys' and young men's access to youth clinics in Sweden. METHODS: Employing a mixed-methods approach, this study investigates interventions, strategies, and factors influencing access to SRH services for boys and young men in Sweden. Firstly, a systematic literature review will be conducted to identify evaluated interventions globally. Secondly, strategies to attracts boys and young men in youth clinics in Sweden will be mapped. Thirdly, case studies in two regions in Sweden - chosen for their demographic and geographic diversity - will be conducted interviewing healthcare providers, managers, policymakers, and boys and young men. Lastly, Q-methodology will be used to rank all identified strategies. Healthcare providers and managers will rank these strategies based on their perceived effectiveness and feasibility while boys and young men will rank the interventions based on perceived effectiveness. DISCUSSION: The added value of this project is generating robust evidence regarding boys and young men's involvement in SRH services, especially their access to youth clinics. This is crucial for (1) developing gender-sensitive services and service delivery models that effectively promote young men's SRH; (2) informing future young men's health policies ensuring that their unique SRH concerns are addressed; and (3) improving young men's participation in SRH provision. This will ultimately foster a culture of shared responsibilities and advance gender equality.

Men's involvement in family planning programs: an exploratory study from Karachi, Pakistan.

BACKGROUND: In Pakistan, family planning has traditionally been perceived as primarily a women's concern, resulting in the exclusion of men from relevant initiatives. This situation is further exacerbated by cultural and social barriers that hinder men's access to family planning services. This study addresses a significant research gap by assessing the extent of family planning service provision for men in urban areas of Karachi. It delves into the exploration of men's involvement in family planning service delivery, identifies existing gaps in services catering to men, records men's perceptions of accessibility and acceptability of these services, and ultimately offers recommendations to enhance men's involvement and strengthen service provision to better meet their needs. METHODS: We employed a qualitative exploratory research design using semi-structured interviews to investigate perceptions regarding family planning service provision to men. This approach involved 25 interviews, comprising eight key informant interviews with stakeholders, eight with service providers, and nine in-depth interviews with married men. RESULTS: This study highlights the limited engagement of men in family planning programs, primarily due to entrenched sociocultural norms that confine female healthcare providers to serving women, hindering men's involvement. While national and provincial policies endorse men's participation, they lack defined roles for male providers. Behavioral and information-sharing barriers at the community level discourage male healthcare providers from collaborating with females. Family planning programs, except for NGO-led vasectomy projects, fail to adequately address men's needs. Despite policy recognition, implementation remains inadequate. Bridging the men's involvement gap necessitates more male providers and improved contraceptive stigma combat training. Further research is vital to explore effective methods for involving men in community and service delivery in family planning. CONCLUSION: There is a need to change the perception that contraception is solely the responsibility of women, as men's participation in family planning in Karachi is limited. Engaging men can yield positive health and non-health outcomes. Culturally sensitive services, developed with community input using a couple-centered approach, are crucial for equitable family planning. Further research is needed to explore men's inclusion strategies in service provision and utilization.

Many family planning efforts focus solely on women, leaving out men, especially in Pakistan, due to cultural and social barriers. This study aimed to explore men's involvement in family planning programs in Karachi. We talked to 25 different people, such as those who run family planning programs, provide services, and married men. We found that men aren't much involved in these programs. Female health providers usually help women, which discourages men from participating or getting involved in such programs. Even though there have been policies to include men since 2002, they don't have specific roles defined. Men don't  discuss family planning much with female providers due to behavioral differences and lack of open communication. Men mostly prefer condoms, and apart from a small NGO-run vasectomy project, there are few programs-tailored to their needs. Although policies exist, they're not fully in practice. To change this, we need more male providers and improved training to reduce the stigma around contraception. Future research should  explore more effective ways to involve men in family planning, both in communities and service levels. Overall, getting men involved in family planning is important, and services need to be developed with input from communities and couples to ensure fairness. More research is needed to figure out the best ways to do this.

A potential trade-off between reproduction and enhancement of thermotolerance in Liriomyza trifolii populations driven by thermal acclimation.

The invasive pest, Liriomyza trifolii, poses a significant threat to ornamental and vegetable plants. It spreads rapidly and causes large-scale outbreaks with pronounced thermotolerance. In this study, we developed L. trifolii strains adapted to high temperatures (strains designated 35 and 40); these were generated from a susceptible strain (designated S) by long-term thermal acclimation to 35 °C and 40 °C, respectively. Age-stage, two-sex life tables, thermal preferences, critical thermal limits, knockdown behaviors, eclosion and survival rates as well as expression of genes encoding heat shock proteins (Hsps) were compared for the three strains. Our findings indicated that the thermotolerance of L. trifolii was enhanced after long-term thermal acclimation, which suggested an adaptive plastic response to thermal stress. A trade-off between reproduction and thermotolerance was observed under thermal stress, potentially improving survival of the population and fostering adaptionary changes. Acclimation at 35 °C improved reproductive performance and population density of L. trifolii, particularly by enhancing the fecundity of female adults and accelerating the speed of development. Although the 40 strain exhibited the highest developmental speed and greater thermotolerance, it incurred a larger reproductive cost. This study provides a theoretical framework for monitoring and controlling leafminers and understanding their evolutionary adaptation to environmental changes.

Possible mechanisms for adverse effects on zebrafish sperm and testes associated with low-level chronic PFOA exposure.

Perfluorooctanoic acid (PFOA), which is widely used during the manufacturing of fluoropolymer coatings and polytetrafluoroethylene, is now a widespread pollutant in the environment and within the human body. This study used zebrafish, an aquatic model species, to investigate how low levels of chronic PFOA exposure affect the reproductive system. The results of the experiments in which zebrafish were exposed to 414 ng/L or 4140 ng/L for 60 days showed a variety of adverse effects on testicular tissue and sperm, including dose-dependent changes in plasma estradiol and testosterone levels, various sperm malformations, decreased sperm motility and concentration, and PFOA-induced oxidative stress and testicular damage with increased rates of apoptosis. In addition, offspring of the zebrafish that had been exposed to PFOA were characterized by increased malformation and mortality. Subsequent transcriptional analyses of the male gonads revealed the significant activation of oxidative stress bioprocesses and immuno-inflammatory signaling pathways, along with the dysregulation of reproductive bioprocesses. In conclusion, low-level chronic exposure to PFOA affects both the reproductive performance of adults and the development of offspring; the mechanisms for these adverse effects involve alterations in several molecular pathways that may be involved in PFOA-induced oxidative stress and reproductive abnormalities. The presented data can be used to assess the ecotoxicity of PFOA to the male reproductive system at environmentally-relevant concentrations.

Investigating the relationship between health and gender equality: What role do maternal, reproductive, and sexual health services play?

Examining the causal nexus between health services and gender equality is of paramount significance in policy formulation and academic inquiry. This paper concentrates on maternal, sexual, and reproductive health, offering a critical narrative review of empirical research exploring the causal relationship between enhanced women's health, stemming from either overall healthcare amelioration or specific interventions, and broader gender equality objectives. A conceptual framework is devised to elucidate the causal pathways between health and gender equality across various dimensions. The final review encompasses 30 empirical papers, revealing both direct and indirect effects of improved maternal, reproductive, and sexual health outcomes on labour participation and educational investment, with fertility decisions and autonomy serving as primary intermediary factors. Evidence predominantly indicates that interventions like contraception, family planning, and abortion policies yield enduring effects beyond health, influencing reproductive choices. Specific medical procedures, such as caesarean deliveries and sterilization, also impact fertility and labour market outcomes. Furthermore, public healthcare infrastructure contributes to combating gender-based violence by facilitating incident reporting and access to protection. Recognizing, documenting, and monitoring these co-benefits arising from improved women's health are pivotal for delineating future health sector priorities and advancing the global gender equality and sustainable development agenda.

Research Note: Evaluating the vertical transmission potential of Salmonella Reading in broiler breeders.

Salmonella Reading (S. Reading) recently emerged as a foodborne pathogen causing extensive human outbreaks in North America from consuming contaminated poultry products, mostly from turkeys. Understanding the transmission dynamics of this pathogen is crucial for preventing future outbreaks. This study investigated the ability of S. Reading to colonize the tissues and contaminate eggs of broiler breeders. We utilized 2 S. Reading strains, marked with bioluminescence gene: the outbreak strain RS330 and a reference strain RS326. We used 32 commercially sourced broiler breeder hens, 34 wk of age, randomly assigned to the 2 treatments (16 hens per strain). Each hen was intravaginally inoculated with 108 CFU of the respective strain on d 1 and was rechallenged on d 4. Eggs were collected daily postchallenge to recover bioluminescent S. Reading strains from the external eggshell surface and internal egg contents. On d 7 postchallenge, 10 hens from each treatment group were euthanized. Ovaries, oviducts, and ceca were aseptically collected to detect S. Reading colonization. Results showed that 70.5% (36 of 51) and 34.5% (19 of 55) of external eggshell surfaces, and 4.0% (2 of 50) and 1.8% (1 of 54) of the internal egg contents tested positive for the outbreak and nonoutbreak strains. Additionally, 40.0% of ovaries, 70.0% of oviduct, and 70.0% of ceca samples from the outbreak strain group, and 20.0% of ovaries, 70.0% of oviduct, and 80.0% of ceca samples from nonoutbreak strain group were positive. No significant difference (P = 0.05) was observed in all the findings among the strains except for the eggshell surface contamination. These findings suggest that S. Reading can effectively colonize reproductive tissues, translocate to the ceca, and contaminate the eggs of hens. Future research is needed to determine whether S. Reading can remain viable within the eggs throughout incubation and until hatching.

Metabolic profile and glycemic response in fully-grown sows born using assisted reproductive technologies.

The aim of the present work was to gain insight into the metabolism of pigs derived from assisted reproductive technologies during their adulthood. Approximately 4h after feeding, a blood sample was taken from 3.5 year old sows born by artificial insemination (AI group, n = 7) and transfer of in vitro produced embryos (IVP group, n = 11) to determine the physiological concentrations of the main biomarkers of carbohydrates (glucose and lactate), proteins (albumin, creatinine and urea) and lipids (cholesterol and triglycerides). Four weeks later, an oral glucose tolerance test (OGTT; 1.75g glucose/kg body weight) was performed after an overnight fast and 1h of water withdrawal. Blood samples were obtained prior (T = 0 min; fasting conditions) and 15, 30, 45, 60, 90, 120, 150, 180, 210 and 240 min after glucose intake. At each time point, glycemia was measured immediately using glucometer test strips, and serum was collected to determine the above metabolites along with insulin and glucagon. After OGTT, the area under the curve (AUC) between sampling times and homeostasis model assessment of insulin resistance (HOMA) indices were calculated. Under physiological conditions, the concentration of metabolites studied was similar between AI and IVP sows. In both groups, fasting decreased cholesterol and increased triglycerides and urea (P < 0.001). However, creatinine and lactate were similar in both groups under physiological and fasting conditions. The expected increase in albuminemia and decrease in glycaemia after fasting was only observed in IVP sows. OGTT revealed a different glucose curve pattern (monophasic in AI and biphasic in IVP group), a lower mean concentration of cholesterol, glucose, lactate, triglycerides in IVP compared to AI pigs (P < 0.01), and a higher mean concentration of albumin, creatinine and insulin in IVP compared to AI group (P < 0.05). On the contrary, no differences were found between groups for mean serum glucagon and urea levels, nor for glucose homeostasis indices HOMA-IR and HOMA-%B. The AUC differed between groups at several time points with larger AUC for creatinine, and smaller AUC for glucose, glucagon, and triglycerides, in IVP pigs than in AI pigs at 180-210 min (P < 0.05). In conclusion, under physiological conditions the metabolic profile of fully-grown AI and IVP sows is similar and within normal ranges. Glucose challenge revealed differences in metabolic and insulin responses between groups but with normal glucose tolerance in both cases.

Global stability of coexistence equilibria for n-species models of facultative mutualism.

We further pursue an investigation on an abstract model characterizing the dynamics of a general class of n-species facultative mutualisms that was initiated in Georgescu et al. (2017),establishing biologically relevant sufficient conditions for the global asymptotic stability of the coexistence equilibria. These conditions are given in terms of per-species limits of growth-to-loss ratios computed at higher population densities, complemented by either monotonicity or sublinearity inequalities, and are observed to hold for n-species versions of mutualistic models in current use. The specific modelling details that require either of these conditions being satisfied are outlined and discussed. As mutualisms can enhance species diversification and facilitate stable coexistence via a plethora of mechanisms, it is then important to understand the stability of speciose mutualisms, our results being of potential interest to theoretical ecologists studying the coexistence of many interacting species and to conservationists aiming for rare species preservation.

Functional and therapeutic significant of heat-shock protein 90 (HSP90) in reproductive cancers.

Reproductive cancers, such as ovarian, cervical, and endometrial carcinomas, have a poor prognosis in metastatic stages. Researchers are continuously seeking improved and safer methods to target cancer-related oncoproteins, addressing the limitations of current treatments, including their limited effectiveness, drug resistance, and off-target effects. Recent advancements in understanding the molecular mechanisms involved in the progress of reproductive cancers have provided valuable insights into potential targeted therapies. By engaging with oncoproteins and co-chaperones, heat-shock protein 90 (HSP90) regulates signaling networks and fixes protein folding errors in cancer cells. The potential of HSP90 inhibition as cancer-targeted treatments is underscored by the continuous discovery and testing of novel HSP90-targeted molecules for their antitumor properties in preclinical and clinical settings. Therefore, this study aims to shed light on the mechanism and recent research breakthroughs of HSP90, as well as provide an in-depth review of their therapeutic potential in reproductive cancers.

Bats as instructive animal models for studying longevity and aging.

Bats (order Chiroptera) are emerging as instructive animal models for aging studies. Unlike some common laboratory species, they meet a central criterion for aging studies: they live for a long time in the wild or in captivity, for 20, 30, and even >40 years. Healthy aging (i.e., healthspan) in bats has drawn attention to their potential to improve the lives of aging humans due to bat imperviousness to viral infections, apparent low rate of tumorigenesis, and unique ability to repair DNA. At the same time, bat longevity also permits the accumulation of age-associated systemic pathologies that can be examined in detail and manipulated, especially in captive animals. Research has uncovered additional and critical advantages of bats. In multiple ways, bats are better analogs to humans than are rodents. In this review, we highlight eight diverse areas of bat research with relevance to aging: genome sequencing, telomeres, and DNA repair; immunity and inflammation; hearing; menstruation and menopause; skeletal system and fragility; neurobiology and neurodegeneration; stem cells; and senescence and mortality. These examples demonstrate the broad relevance of the bat as an animal model and point to directions that are particularly important for human aging studies.

Reproductive factors and mammographic density within the International Consortium of Mammographic Density: A cross-sectional study.

BACKGROUND: Elevated mammographic density (MD) for a woman's age and body mass index (BMI) is an established breast cancer risk factor. The relationship of parity, age at first birth, and breastfeeding with MD is less clear. We examined the associations of these factors with MD within the International Consortium of Mammographic Density (ICMD). METHODS: ICMD is a consortium of 27 studies with pooled individual-level epidemiological and MD data from 11,755 women without breast cancer aged 35-85 years from 22 countries, capturing 40 country-& ethnicity-specific population groups. MD was measured using the area-based tool Cumulus. Meta-analyses across population groups and pooled analyses were used to examine linear regression associations of square-root (√) transformed MD measures (percent MD (PMD), dense area (DA), and non-dense area (NDA)) with parity, age at first birth, ever/never breastfed and lifetime breastfeeding duration. Models were adjusted for age at mammogram, age at menarche, BMI, menopausal status, use of hormone replacement therapy, calibration method, mammogram view and reader, and parity and age at first birth when not the association of interest. RESULTS: Among 10,988 women included in these analyses, 90.1% (n = 9,895) were parous, of whom 13% (n = 1,286) had ≥ five births. The mean age at first birth was 24.3 years (Standard deviation = 5.1). Increasing parity (per birth) was inversely associated with √PMD (ß: - 0.05, 95% confidence interval (CI): - 0.07, - 0.03) and √DA (ß: - 0.08, 95% CI: - 0.12, - 0.05) with this trend evident until at least nine births. Women who were older at first birth (per five-year increase) had higher √PMD (ß:0.06, 95% CI:0.03, 0.10) and √DA (ß:0.06, 95% CI:0.02, 0.10), and lower √NDA (ß: - 0.06, 95% CI: - 0.11, - 0.01). In stratified analyses, this association was only evident in women who were post-menopausal at MD assessment. Among parous women, no associations were found between ever/never breastfed or lifetime breastfeeding duration (per six-month increase) and √MD. CONCLUSIONS: Associations with higher parity and older age at first birth with √MD were consistent with the direction of their respective associations with breast cancer risk. Further research is needed to understand reproductive factor-related differences in the composition of breast tissue and their associations with breast cancer risk.

Sexual and reproductive health service utilization and associated factors among high school students in Ethiopia: systematic review and meta-analysis.

Introduction: Several studies have been done on the utilization of sexual and reproductive health services by high school students in Ethiopia, but they have yielded inconsistent results. This study aimed to evaluate the extent to which high school students in Ethiopia are using sexual and reproductive health services by conducting a systematic review and meta-analysis. Methods: Various electronic databases such as PubMed, Cochrane Library, AJOL, Google Scholar, and Grey Literature were used to search for relevant articles. Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines were followed for this review and meta-analysis. Heterogeneity was assessed using I2 and Cochrane Q statistical tests, and data analysis was done with STATA 17 software. Random effect meta-analyses were used to determine the overall utilization rate of sexual and reproductive health services. Result: This review included 20 studies with 12, 215 study participants. The pooled magnitude of sexual and reproductive health service utilization among high school students in Ethiopia was 29.79% (95% CI: 25.14, 34.43). Students with grades 11-12 (AOR = 2.33, 95% CI: 1.39, 3.90), aged between 20 and 24 years (AOR = 2.61; 95% CI: 1.79-3.81), having higher level of knowledge towards sexual and reproductive health issues (AOR = 3.10; 95% CI: 1.67-5.77), previous history of sexual intercourse (AOR = 4.18; 95% CI: 2.59-6.75), previous history of sexually transmitted infection (AOR = 3.74; 95% CI: 2.22-6.31), presence of a reproductive health service facility in the school (AOR = 2.55; 95% CI: 1.72-3.77), and ever-discussed reproductive health issues (AOR = 4.04; 95% CI: 1.62-10.03) were more likely to utilize sexual and reproductive health services. Conclusions: The overall utilization of sexual and reproductive services among high school students in Ethiopia was found to be low as compared to SDG 3.7. Older individuals with higher education levels and knowledge about sexual and reproductive health services, as well as those who have had previous sexual experiences or discussions about sexual health, are more likely to utilize reproductive health services. To increase utilization, the Ministry of Health and the Ministry of Education should prioritize these factors.

Impact of Hysteroscopic Instillation of Autologous Platelet-Rich Plasma on Pregnancy Outcomes in Patient With Recurrent Implantation Failure: A Case Report.

Recent advancements in assisted reproductive technology (ART) have enabled couples to achieve pregnancy, who were previously unable to conceive. However, recurrent implantation failure (RIF) remains a significant challenge. This case study exhibits the effective use of hysteroscopic-guided platelet-rich plasma (PRP) instillation in the treatment of a female patient aged 33 who was nulliparous and diagnosed with RIF and a thin endometrium, which resulted in primary infertility. The couple had a history of 10 years of infertility and had previously undergone ART procedures, including intrauterine insemination (IUI) and intracytoplasmic sperm injection (ICSI), which failed. The female partner was diagnosed with a thin endometrium (<7 mm) and underwent hysteroscopy, revealing no other significant intrauterine pathologies. Following hormonal treatment and ovum pick-up, hysteroscopic PRP was administered, resulting in improved endometrial thickness (ET) and successful embryo implantation, as evidenced by a positive serum ß-hCG level of 1470 mIU/mL. This case demonstrates the hysteroscopic injection of PRP's potential for increasing endometrial receptivity and enhancing ART outcomes in women with RIF due to thin endometrium, making it a promising alternative to conventional therapies.

Characterization of the reproductive strategy of invasive Round Goby (Neogobius melanostomus) in the Upper Danube River.

Originating from the Black and Caspian seas, the Round Goby (Neogobius melanostomus) has become one of the most successful invaders of freshwater ecosystems. In this study, we provide a characterization of the reproductive strategy of an established population of Round Gobies in the Upper Danube river including sex ratio, fluctuations of gonadosomatic index (GSI), analysis of timing of spawning as well as of clutch and egg size. We compare these results to other studies from the native and invaded range. In the Danube, the Round Goby population was found to be female dominated, however fluctuations in magnitude of female bias were observed between months. Monitoring of the population across 1.5 years revealed that GSI was highest from April to June, while lowest values were observed in August and September. Using time-series analysis, a delayed effect of temperature on GSI was found for females and males, while a quicker response of GSI levels to photoperiod and discharge was observed for females. GSI increased with body size for females and eggs were found to be significantly larger in May, however clutch sizes did not differ between months. Results of a literature review revealed great differences in timing and length of spawning season as well as sex ratio between populations throughout the distribution range, which can probably be explained by climatic and photoperiodic conditions together with the time since invasion and the high plasticity of Round Gobies.

Beyond borders: The global impact of violating reproductive human rights.

A fundamental component of the basic right to health is the right to sexual health, encompassing an individual's right to decide freely on matters of sexual and reproductive health without discrimination. Provision of these rights is inextricably linked with a wide range of other internationally agreed upon human rights, including the right to information, participation, and equality. Evidence has shown that provision of these rights not only improves maternal and neonatal health, but also healthcare worker safety and the provision of a vast array of critical and necessary medical care. And yet, too often-and with increasing frequency-sexual and reproductive rights are being violated worldwide, with rising taboos, stigma, and discrimination, particularly within abortion, contraception, and fertility care. FIGO strongly supports comprehensive, equitable, and accessible sexual and reproductive health care for all individuals, recognizing that these rights are essential components of global health and fundamental human rights. This includes a particular emphasis on special populations, healthcare workers, and women and girls in crisis zones. FIGO encourages its member societies to deliver comprehensive sexual and reproductive health care, advocate for coverage for sexual and reproductive health care, become involved in analyzing barriers to access within health systems, and provide nonjudgemental, confidential, person-centered care.

FemTech: empowering reproductive rights or FEM-TRAP for surveillance?

The emergence of FemTech technologies promises to revolutionize women's health and reproductive rights but conceals an insidious trap of surveillance and control in the hands of private and state actors. This article examines the extent to which FemTech technologies, under the guise of empowerment, enable private actors to play a leading role in managing reproductive rights, replacing largely inactive States in this crucial function. The analysis shows how private FemTech companies are becoming critical players in implementing and defending these rights, often in response to the inaction or inadequacies of States. The article approaches the FemTech phenomenon from several angles, including the promises of empowerment, concerns about surveillance and control, and the ambivalent roles of private actors as implementers and defenders of reproductive rights. This structure makes it possible to offer a critical analysis of the legal, societal, and ethical implications of FemTech, highlighting the tensions between the promises of empowerment and the risks of surveillance and control.
