Fertility Rate

Where connections between demography and politics are examined in the literature, it is largely in the context of the effects of male aspects of demography on phenomena such as political violence. This project aims to place the study of demographic variables’ influence on politics, particularly on democracy, squarely within the scope of political and social sciences—and—to focus on the effects of woman-related demographics, namely fertility rates. I test the hypothesis that demographic variables—female-related predictors in particular—have an independent effect on political structure. Comparing different countries over time, when fertility rates decline, we observe a growth in democracy. In the theoretical framework developed, it is family structure, and the economic and political status of women that account for this change at the macro and micro levels. Findings based on data for over 140 countries over 3 decades are robust when controlling not only for alternative effects, but also for reverse causality and data limitations.

Outlines the experiences of East Germany as unification takes place. Presents the findings of a study analysing three groups of East Germans in their transitions from education to employment and subsequent careers from 1985 onwards. Suggests that the findings indicate that changes in macro structure and life courses are closely interrelated. Covers mobility, unemployment, retraining, competition, fertility rates and coping

Although its measurement may be difficult, the maternal mortality ratio (MMR) is a key indicator of maternal health globally. In Pakistan each year over five million women become pregnant, and of these 700,000 (15% of all pregnant women) are likely to experience some obstetrical and medical complications. An estimated 30,000 women die each year from pregnancy-related causes, and the most recent estimates indicate that the MMR is 276 per 100,000 births annually. In this review, we describe the status of maternal health and survival in Pakistan and place it in its wider context of key determinants. We draw attention to the economic and social vulnerability of pregnant women, and stress the importance of concomitant broader strategies, including poverty reduction and women's empowerment. Undernutrition for girls, early marriage, and high fertility rates coupled with unmet needs for contraception are important determinants of maternal ill health in Pakistan. Our review also examines...

Purpose Embryological and clinical efficacy of gonadotropin-releasing hormone (GnRH) antagonist and agonist stimulation protocols in non-obese women with polycystic ovarian syndrome (PCOS) were compared. Methods A prospective randomized study. Setting: Medical University Hospital. Patients: 70 infertile PCOS patients; 33 in GnRH antagonist and 37 in GnRH agonist group. Results Similar mature metaphase II oocyte rate (76% vs. 76%) was observed in both protocols. Optimal pronuclear morphology zygotes dominated in both groups (64% vs. 66%). Transferred embryo quality did not differ in both protocols. No significant differences between both protocols were found in delivery rate (p = 0.481), pregnancy rate (p = 0.810), multiple pregnancy rate (p = 0.501), miscarriage rate (p = 0.154), fertilization rate (p = 0.388) and implantation rate (p = 1.000). Duration of stimulation and total follicle-stimulating hormone (FSH) dose were significantly lower in GnRH antagonist protocol (p = 0.0005). Conclusions GnRH antagonist and agonist protocols in non-obese PCOS patients yield similar embryological and clinical outcomes. Shorter duration of treatment and lower FSH requirement in GnRH antagonist group may be financially beneficial and therefore attractive for patients.

The fertilization and activation of fishoocytes are vital, but unfortunatelyoverlooked, processes in fisheries research.This paper sets out to review our presentunderstanding of these important events inteleost fish and, drawing comparisons withmammalian research, to highlight areas in whichresearch effort is urgently required. Presently, the commercial culture of manyimportant freshwater, but especially marine,teleosts is beset by problems associated withfertilization, hatching and early embryonicdevelopment. These problems have beenparticularly acute in certain species leadingto the application of spawning inductiontechnologies in an effort to optimizeproduction. Increased knowledge of theprocesses of egg activation and fertilizationin these groups of fish is likely to makesignificant contribution to commercialaquaculture. Studies of a wide variety ofanimal and plant species has demonstrated thatdevelopment at fertilization is triggered by anincrease in intracellular Ca2+concentration within the egg that occurs aseither a single transient or a series ofdistinctive oscillations depending upon thespecies under investigation. This increase inintracellular Ca2+ activates the egg andalso appears to play an important role in laterembryonic development. Teleost reproductivestrategies and more importantly, teleostoocytes and spermatozoa, exhibit a remarkablevariety of adaptations. Currently, studies ofegg activation in teleosts are confined tolaboratory species such as medaka Oryziaslatipes and zebrafish Brachydanio rerio.Nevertheless, even between these two species,although an increase in intracellular Ca2+appears to be the trigger in both cases, themechanism of Ca2+ release may be quitedifferent. Activation in medaka is initiatedonly through direct contact with conspecificsperm, suggesting the involvement of asperm-specific factor, while zebrafish eggsappear to require only contact with theexternal spawning medium. In view of the highlyvariable fertility rates evident in manycommercially cultured teleosts, it could bevery rewarding to investigate the mechanism ofegg activation in representative teleost groupsusing the findings and theories emerging fromother animal groups as a starting point. Inorder to successfully conduct such aninvestigation, it will be necessary to employ acombination of physiological, molecular andrecombinant approaches.
