In England in 1800 a profound change occurred that ushered in an important component in the regime of modern economic growth. In pre-industrial England, from 1250 to 1800, the rich produced many more surviving children than the poor. From 1800 to 1875 there was no association between wealth and net fertility. And after 1875 wealth became strongly negatively associated with net fertility. Why th...

Results reveal that farmers are well aware of the adverse environmental impacts of modern agricultural technology, although their awareness remains confined within visi...

METHODS In 2008, we conducted a nationwide survey in Germany in which we asked 4689 female and male patients who had been treated for cancer in childhood or adolescence for information on menstruation,...

STUDY DESIGN Four physicians performed embolization procedures at various facilities. Patients were asked if fertility was an issue prior to embolization. We measured follicle-stimulating hormone levels b...
In this article, we develop a fully integrated and dynamic Bayesian approach to forecast populations by age and sex. The approach embeds the Lee-Carter type models for forecasting the age patterns, with associated measures of uncertainty, of fertility, mortality, immigration, and emigration within a cohort projection model. The methodology may be adapted to handle different data types and sourc...
Two women, a Saudi Arab and a Caucasian, aged 28 and 41 years, had a long history of polycystic ovary syndrome (PCOS) and primary infertility, which was refractory to various treatment modalities. Both later developed type 2 diabetes, managed initially with metformin; rosiglitazone was added later to improve glycaemic control. Both conceived spontaneously, resulting in singleton and twin pregna...
Using a cross-country data drawn from 40 countries and a multiple regression analysis, this paper examines the impact of birth control devices on the rate of fertility in sub-Saharan Africa. Our a-priori expectations are that the more women used birth control devices, the less will be the fertility rate in sub-Saharan Africa. The result obtained from the study indicates that except for withdraw...

Introduction There has been a huge amount of media interest in the development of new home fertility tests for couples trying to conceive. The female fertility tests are marketed as devices that measure the quantity of healthy eggs women have left (ovarian reserve). Ovarian reserve is measured by determining the level of follicle-stimulating hormone (FSH) in the urine. High levels of FSH sugges...
