Résumé :

At below replacement level, fertility changes are subtle and complex; distinguishing statistically significant trends from random shifts is becoming a relevant issue. The probabilistic fertility table describes the uncertainty of the childbearing process, and provides a significance test for the annual changes of various fertility measures, which is essential for distinguishing a statistically significant change from a random fluctuation. This paper provides an analytical model for the total fertility of the probabilistic fertility table, and extends the significance test to period trends that include multiple annual changes. The extended significance test indicates that complex annual changes could accumulate to become a significant trend. Applying the analytical model and extended test to the total fertility of Canada, it indicates that the 2002–11 increase trend is statistically significant and, therefore, supports project future increases of total fertility.En-dessous du seuil de remplacement des générations, les changements à la fertilité sont subtils et complexes. Aussi, il est devenu pertinent de pouvoir distinguer les tendances significatives au plan statistique des écarts aléatoires. Le tableau probabiliste de fertilité décrit l’incertitude liée au processus de reproduction et fournit un critère de signification des changements annuels dans les diverses mesures de fertilité, élément essentiel pour distinguer un changement important au plan statistique des fluctuations aléatoires. Cet article fournit un modèle analytique pour l’ensemble du tableau probabiliste de fertilité et élargit la portée de cette mesure aux tendances dans le temps incluant les multiples changements annuels. Ce critère élargi indique que les changements complexes annuels peuvent représenter une tendance significative. En appliquant le modèle analytique et le critère au tableau de fertilité du Canada, on constate que la tendance à la hausse de 2002–11 est importante au plan statistique et, par conséquent, augure des hausses futures dans la fertilité totale.

Résumé :

The rate of population growth is caused by migration, birth, and death. Fertility is the most dominant influence. Mojokerto district is a rapidly growing district because of the development of the main line of development, but the negative effects of that result result in fertility issues particularly from the birth rate (fertility). Mojokerto district has always increased in population and mojosari district has become one of the highest population. The village of mojosulur was one of the fertility donors of 305 inhabitants of the mojosari district. The purpose of this study is to know how much family income, education level, and early marriage ages affect fertility in mojosulur village by using a linear regression analysis method. As well as a statistical test of the t for a partial regression relationship. The results of family income variables do not significantly affect fertility and those of the first degree and age of marriage significantly affect fertility. Laju pertumbuhan penduduk disebabkan oleh besarnya migrasi, kelahiran, dan kematian. Fertilitas merupakan pengaruh yang paling mendominasi. Kabupaten Mojokerto merupakan kabupaten yang terus berkembang secara pesat karena tergabung dalam wilayah pembangunan Gerbangkertosusila, namun demikian dampak negatif akibat dari hal tersebut munculah masalah-masalah di bidang kependudukan khususnya akibat dari tingkat kelahiran (fertilitas). Kabupaten Mojokerto selalu meningkat jumlah penduduknya dan Kecamatan Mojosari menjadi salah satu kecamatan dengan jumlah penduduk tertinggi. Desa Mojosulur merupakan salah satu penyumbang fertilitas sebesar 305 jiwa di Kecamatan Mojosari. Tujuan penelitian ini adalah untuk mengetahui besar pengaruh pendapatan keluarga, tingkat pendidikan, dan usia kawin pertama terhadap fertilitas di Desa Mojosulur dengan menggunakan metode analisis regresi linier berganda. Serta dilakukan uji statistik Uji t untuk menguji hubungan regresi secara parsial. Hasilnya variabel Pendapatan Keluarga tidak berpengaruh signifikan terhadap fertilitas dan variabel Tingkat Pendidikan serta Usia Kawin Pertama berpengaruh signifikan terhadap fertilitas.

Résumé :

Migrasi merupakan salah satu faktor yang memengaruhi dinamika penduduk, baik melalui jumlah migran maupun fertilitas migran. Jumlah migrasi yang besar ke Provinsi Jawa Barat merupakan salah satu penyebab peningkatan jumlah penduduk yang cukup besar. Jika migran memiliki fertilitas yang lebih tinggi dibandingkan dengan nonmigran, maka pengaruh tersebut akan lebih besar lagi. Penelitian ini bertujuan untuk mengkaji perbedaan fertilitas antara migran dan nonmigran serta faktor-faktor yang memengaruhi fertilitas di Jawa Barat. Data yang digunakan adalah data Survei Sosial Ekonomi Nasional (Susenas) tahun 2015. Analisis dilakukan menggunakan statistik deskriptif dan inferensial. Hasil penelitian menunjukkan terdapat kecenderungan migran memiliki fertilitas yang lebih tinggi dibandingkan dengan nonmigran. Sementara itu, faktor sosial ekonomi yang berpengaruh terhadap fertilitas adalah pendidikan, usia kawin pertama, penggunaan alat kontrasepsi, dan kegiatan utama (pekerjaan). Migration is one of the factors that influences the dynamics of population, both through the number of migrants and the fertility of migrants. The large number of migrants to West Java Province is one of the causes of a considerable increase in population. If migrants have higher fertility than non-migrants, the effect will be even greater. This study aims to examine the difference of fertility between migrants and non-migrants as well as factors affecting fertility in West Java. The data used is 2015 National Socio-Economic Survey (Susenas). The analysis is done using descriptive and inferential statistics. The results show that there is a tendency for migrants to have higher fertility compared with non-migrants while the socio-economic factors that have an effect on fertility are education, first marriage age, use of contraceptives, and main activities (work).

Résumé :

Abstract Introduction: Northern Ontario has a population of approximately 800,000 people distributed over 806,707 km2. Before 2018, the only fertility treatment centre in Northern Ontario was located in Thunder Bay; many patients travelled south for care. In 2018, the Northeastern Ontario Women’s Health Network (NEOWHN) opened in Sudbury, providing fertility treatments to people living in Northeastern Ontario. The goal of this study was to determine if proximity to this new fertility centre increases one’s chance of achieving pregnancy when undergoing fertility treatment. Secondary outcomes included the quantity and types of fertility investigations and treatments completed by patients. Materials and Methods: A retrospective chart review was performed for all patients seeking fertility treatment at NEOWHN between January 2019 and December 2020. Traveling >100 km to access healthcare was considered to be a clinically significant determinant of health. Results: Seven hundred and 5 patients were seen in consultation for fertility services at NEOWHN during the study period. One hundred eighty-one of 478 (37.9%) patients living <100 km from NEOWHN achieved pregnancy compared to 39 of 227 (17.2%) patients living >100 km from NEOWHN (P < 0.01). Conclusion: Living in proximity (<100 km) to NEOWHN increased the likelihood that individuals in Northeastern Ontario would seek fertility services and would achieve pregnancy. Financial constraints and inaccessibility likely play a role in this, but further studies are needed to explain this difference. Introduction: Le Nord de l’Ontario compte une population d’environ 800,000 personnes réparties sur 806,707 km2. Avant 2018, le seul centre de traitement de la fertilité du Nord de l’Ontario était situé à Thunder Bay; de nombreux patients SE rendaient dans le sud pour recevoir des soins. En 2018, le Northeastern Ontario Women’s Health Network (NEOWHN-le Réseau de santé des femmes du Nord-Est de l’Ontario) a ouvert ses portes à Sudbury, offrant des traitements de fertilité aux personnes vivant dans le Nord-Est de l’Ontario. L’objectif de cette étude était de déterminer si la proximité de ce nouveau centre de fertilité augmente les chances d’obtenir une grossesse lors d’un traitement de fertilité. Les résultats secondaires comprenaient la quantité et les types d’examens et de traitements de fertilité effectués par les patients. Méthodes: Une étude rétrospective des dossiers a été réalisée pour tous les patients cherchant un traitement de fertilité au NEOWHN entre janvier 2019 et décembre 2020. Le fait de voyager >100 km pour accéder aux soins de santé a été considéré comme un déterminant de la santé cliniquement significatif. Résultats: Seven hundred and 5 patients ont été vus en consultation pour des services de fertilité au NEOWHN pendant la période d’étude. One hundred eighty-one des 478 (37.9%) patientes vivant à moins de 100 km du NEOWHN ont obtenu une grossesse, contre 39 des 227 (17.2%) patientes vivant à plus de 100 km du NEOWHN (P < 0.01). Conclusion: Le fait de vivre à proximité (<100 km) du NEOWHN augmente la probabilité que les habitants du Nord-Est de l’Ontario aient recours à des services de fertilité et obtiennent une grossesse. Les contraintes financières et l’inaccessibilité jouent probablement un rôle à cet égard, mais d’autres études sont nécessaires pour expliquer cette différence.

Résumé :

The Russian Fertility Database contains a series of fertility indicators by birth order for Russia from 1946 to 2022, cohort fertility tables by birth order, and fertility rates by birth order for Russian women born between 1932 and 1988. All fertility indicators are calculated using data from official population statistics provided by the Federal State Statistics Service. The article describes the structure of the database, the source data, and the methodology of calculating period and cohort fertility rates, as well as cohort fertility tables by birth order. The Russian Fertility Database can be used for research, analytical materials, reports, presentations, as well as for educational purposes. The data allow us to analyze changes in the age profiles of fertility, the mean age at birth, the dynamics of the total fertility rate as period and cohort indicator for all birth orders combined and by birth order, parity distribution of women with specific number of children ever born and parity progression ratios. The data are in .xlsx format and are available on the web page: https://demogr.hse.ru/RFD.

Résumé :

Greece is typical of the European experience vis-a-vis fertility decline. Its total fertility rates (TFR) fell below the population replacement level of 2.1 in 1981 and now remains at 1.3. A review of the fertility policy debates in Europe and in Greece, in particular, reveals that policy debates and discourses are biased with unfounded assumptions and judgements regarding causes and consequences of fertility decline. A review of existing literature and the researcher's own empirical work presents sufficient evidence to support this conclusion. In addition, a comparison of such political and institutional perspectives with the fertility experiences and perspectives of a sample population in Greece finds that the institutional perspectives are not always adequately informed of the ground realities. It is therefore concluded that significant informational gaps are present in Greek fertility policy debates. It is also theorised that such knowledge vacuums are one of the reasons why policy initiatives fail to deliver.

Résumé :

A Masters Thesis, presented as part of the requirements for the award of a Research Masters Degree in Economics from NOVA – School of Business and Economics<br>This research is an empirical assessment of the causal relationship between democracy and birth rates. The question under study is whether a country is more likely to experience fertility declines as it becomes more democratic, holding the other country's characteristics constant. This study goes beyond the existing literature to establish a causal relationship between democratization and fertility declines. To establish a causal relation we adopt two complementary strategies. The first is to include country fixed effects in the estimation and the second is to use an instrumental variables approach. The results suggest a robust negative causal relationship between democracy and birth rates. We interpret the effect of political rights on fertility as stemming from a decrease in overall societal risk, which diminishes as political institutions mature.

Résumé :

BACKGROUND: The long-term decline in cohort fertility in highly developed countries has been widely documented. However, no systematic analysis has investigated which parity contributed most to the fertility decline to low and very low levels. Objective: We examine how the contribution of changing parity progression ratios varied across cohorts, countries, and broader regions in Europe, North America, Australia, and East Asia. We pay special attention to countries that reached very low completed cohort fertility, below 1.75 children per woman. Methods: Using population censuses and large-scale surveys for 32 low fertility countries, we decompose the change in completed cohort fertility among women born between 1940 and 1970. The decomposition method takes into account the sequential nature of childbearing as a chain of transitions from lower to higher parities. Results: Among women born between 1940 and 1955, the fertility decline was mostly driven by reductions in the progression ratios to third and higher-order births. By contrast, among women born between 1955 and 1970, changes in fertility showed distinct regional patterns: In Central and Eastern Europe they were fuelled by falling second-birth rates, whereas in the German-speaking countries, Southern Europe, and East Asia decreases in first-birth rates played the major role. Conclusions: Pathways to low and very low fertility show distinct geographical patterns, which reflect the diversity of the cultural, socioeconomic, and institutional settings of low fertility countries. Contribution: Our study highlights the importance of analysing parity-specific components of fertility in order to understand fertility change and variation. We demonstrate that similar low levels of completed cohort fertility can result from different combinations of parity-specific fertility rates.

Texte intégral

Résumé :

Preservation of female fertility is an important issue today. There are a few effective clinical options for preserving female fertility. Conventional IVF followed by embryo cryopreservation is the only established procedure but is not applicable to all women. Oocyte cryopreservation avoids the ethical and moral concerns related to cryopreservation of embryos but conventional slow freezing methods are associated with low survival rate of oocytes. The main objective of this translational research thesis was to develop an efficient and safe methodology for oocyte cryopreservation that is clinically applicable for female fertility preservation. Specific research objectives were to investigate cryobiology of oocytes in terms of: 1) cryoprotectant (CPA) toxicity effect on oocyte ultra-structures and embryonic developmental potential; 2) Vitrification versus conventional slow freezing of oocytes and their effects of oocyte structures and embryonic developmental potential; 3) Vitrification of embryos using the McGill Cryoleaf and its effect of embryonic development and DNA fragmentation; 4) Clinical efficacy of oocyte vitrification in prospective clinical trials; 5) Effects of oocyte vitrification in terms of the clinical obstetrical and perinatal outcomes; 6) Clinical applications of vitrification of oocytes for preservation of female fertility. The CPA mixture of ethylene glycol (EG) and 1,2-propanediol (PROH) was found to be the most suitable combination for oocyte vitrification, resulting in high embryo development and the least DNA fragmentation. Vitrification of oocyte using the CPA mixture of EG and PROH in combination with the McGill Cryoleaf system is superior to the conventional slow-cooling method, resulting in better preservation of egg ultra-structures and functions. The reduced embryonic development potential of cryopreserved oocyte is related to increased DNA fragmentation and activation of caspase enzymes. Vitrification of human oocytes using the McG<br>Préservation de la fécondité est un sujet important à ce jour. Il y a peu de traitements effectifs pour préserver la fécondité des femmes. La fécondation in vitro (FIV) conventionnelle suivie par la cryoconservation des embryons est la seule procédure bien établie. Cependant, celle-ci n'est pas possible pour certaines femmes. La cryopréservation des ovocytes évite les problèmes éthiques et moraux reliés à la cryoconservation des embryons. Cependant, les méthodes de congélation lente sont associées à des taux de survie des ovocytes faible. Les objectifs principaux de cette thèse de recherche translationnelle était de développer une méthode efficace et sécuritaire pour la cryopréservation des ovocytes qui est cliniquement applicable pour la préservation de la fécondité des femmes. Les objectifs spécifiques de cette recherche étaient d'étudier la cryobiologie des ovocytes à propos de : 1) l'effet toxique du cryoprotectant sur l'ultra-structures des ovocytes et le potentiel de développement des embryons; 2) la vitrification versus la congélation lente des ovocytes et leur effets sur la structure des ovocytes et le potentiel de développement embryonnaire; 3) la vitrification des embryons en utilisant le McGill Cryoleaf et son effet sur le développement embryonnaire et la fragmentation de l'ADN; 4) l'efficacité clinique de vitrification des ovocytes dans des études prospectives cliniques; 5) les effets de long terme de vitrification des ovocytes au niveau des résultats obstétriques et périnatals; 6) l'application clinique de vitrification des ovocytes pour la préservation de la fécondité des femmes. Le mélange de CPA de l'éthylène glycol (EG) et de 1-2 propanediol (PROH) a été trouvé d'être la combinaison la plus convenable pour la vitrification des ovocytes en donnant des résultats de développement embryonnaire supérieur et à un taux de fragmentation de l'ADN diminué.

This study of Fertility Differentials in Bangladesh is based on a subset of data obtained from the 1983 Bangladesh Contraceptive Prevalence Survey. The focus of the study is to identify the variables that significantly affect the cumulative fertility of women in Bangladesh and to examine differentials in fertility.Path analysis has been used for analyzing the data of this thesis. Differentials in fertility are examined in terms of selected demographic and socio-economic characteristics of the ever married women and their husbands.The study shows that age of women has the highest effect on number of children ever born. Religion has positive and significant direct effects on fertility. Education of women has significant negative effects on fertility. Employment status of women effect fertility negatively in rural Bangladesh. The results of this study also suggest that high fertlity in Bangladesh will persist if immediate action is not taken to halt it.<br>Department of Mathematical Sciences

Résumé :

Infertility affects 15 % of couples, which corresponds to 60 - 80 million worldwide. The microenvironments in which the oocyte, embryo and fetus mature are vital to the establishment and development of a healthy pregnancy. Different biological systems, such as angiogenesis, the immune system and apoptosis need to be adequately regulated for pregnancy to occur and progress normally. The overall aim of this thesis was to investigate the impact of Histidine-rich glycoprotein (HRG) and Src homology 2 domain-containing adapter protein B (SHB) on human female fertility. HRG is a plasma protein that regulates angiogenesis, the immune system, coagulation/fibrinolysis and apoptosis, by building complexes with various ligands. The impact of HRG on fertility is studied here for the first time. HRG is present in follicular fluid, the Fallopian tube, endometrium, myometrium and placenta. HRG distribution within embryo nuclei depends on developmental stage. Blastocysts express and secrete HRG. The HRG C633T single nucleotide polymorphism (SNP) appears to affect the chance of pregnancy and, correspondingly, parameters associated with pregnancy in IVF. Additionally, this HRG genotype may increase the risk in IVF of only developing embryos unfit for transfer. SHB is an adaptor protein involved in intracellular signaling complexes that regulate angiogenesis, the immune system and cell proliferation/apoptosis. Shb knockout mice have altered oocyte/follicle maturation and impaired embryogenesis. The impact of three SHB polymorphisms (rs2025439, rs13298451 and rs7873102) on human fertility is studied for the first time. The SNP prevalences did not differ between infertile and fertile women. BMI, gonadotropin dosages, the percentage of immature oocytes, the number of fertilized oocytes, the percentage of good-quality embryos and the day of embryo transfer seems to be affected by SHB genotype. In conclusion, HRG and SHB appear to influence female fertility. They are potential biomarkers that might be used for predicting pregnancy chance in infertile women. Knowledge of these genotypes may improve patient counseling and individualization of treatment.

Résumé :

The continuous decrease in population numbers, driven partly by the decline in fertility rates in Moldova, necessitates ongoing monitoring of this area. The study aims to explore the evolution of fertility in Moldova in the last three decades. The research is based on the National Bureau of Statistics’ vital data, including the females aged 15-49, the number of live births, and the distribution of births by mother's age and birth order from 1991 to 2023. Classic demographic methods were employed to analyse fertility, including total fertility rate, age-specific fertility rates, the mean age of mothers at first birth, and the proportion of live births by birth order and residence. The results regarding fertility in the Republic of Moldova in the analysed period highlight a continuous decline in the number of births and a postponement of the age at which women have their first child. The most marked decline in fertility is among women aged 15-24, whose contribution to overall births dropped from 55% in 1991 to an expected 26% in 2023. This shift underscores a clear trend of delayed childbearing, as fertility rates have risen among women aged 25-34, pointing to a societal shift toward postponing childbirth. Despite improving living standards, Moldova faces a total fertility rate of 1.6 children per woman, below the generational replacement threshold, contributing to a long-term demographic decline.

Résumé :

The decades-long low fertility of the population of Serbia is one of the biggest social challenges and a key component of population dynamics in the long term. Recent research suggests that the reduced progression to first and second child poses an increasingly significant challenge to the recovery of the total fertility rate despite the widespread perception that this is a reduction in higher child parity. At the same time, the pronounced gender imbalance in the spatial distribution of the population in their prime reproductive ages accelerates the processes of population aging and poverty in Serbia, despite the policy makers' goals presented through key national strategies regarding the country's sustainable development. Demographic analyses of changes in fertility patterns of the population in Serbia typically refer to females. Limiting the collection and interpretation of fertility data to women may lead to ignoring the specifics of men's reproductive behaviour, or to the assumption that the level, patterns, and changes in fertility do not differ significantly between men and women. The results of the 2022 Census in Serbia for the first time provide an opportunity to assess male fertility and perform a gender-sensitive analysis of fertility patterns. Existing research suggests that male fertility in Europe, especially in Eastern Europe, is lower than female fertility in recent periods, and that male fertility has declined faster than female fertility. Although the analysis of the results of the 2022 Census cannot conclude how this pattern has changed over time in Serbia, it will be very important to determine, from the aspect of pronounced differences in demographic capacities between areas and regions of Serbia that affect the demographic resilience of the country, what (dis)similarities exist between female and male fertility patterns, especially in their spatial distribution and settlement type. The aim of the paper is to identify patterns, correlations and trends in the fertility of the population of Serbia using statistical methods of longitudinal analysis of cohort fertility indicators of men and women - cumulative and specific according to age, birth order of the child, marital status, education and type of settlement based on the special processing of the 2022 Census data. The results will show whether current generations in reproductive age reach, exceed or fall behind the fertility level of previous generations. Also, by comparing these results with those of the 2011 Census, it will be possible to determine whether there have been changes in female fertility patterns in the intercensal period regarding relations between frequency of births, number of live births and mean age of women at birth of first child. The results of the analysis will contribute to a better understanding of the reproductive patterns of the population in Serbia, thus possibly helping in creation of more adequate policy measures in the field of family planning.
