AIM To investigate the marital status and fertility in long-term survivors of high-grade osteosarcoma. PATIENTS AND METHODS We surveyed the marital rate (number of married persons/total number of persons) in 46 long-term survivors of osteosarcoma who were treated in our hospital between 1976 and 2002. In addition, we examined the fertility rate (number of persons having offspring/number of ma...

During the past 20 years fertility patterns within England and Wales have changed considerably. The total fertility rate experienced a prolonged decline during the 1990s and hit a record low in 2001. Since then the level of fertility has increased fairly rapidly. Over the two decades, fertility has been constantly increasing at ages above 30, and as a consequence the mean age of motherhood has ...

CONTEXT Contraceptive prevalence increased by nine percentage points from 1993 to 2000 in Bangladesh, but there was almost no decline in the total fertility rate. METHODS Data from the 1999-2000 Bangladesh Demographic and Health Survey and from the Matlab Demographic Surveillance System area collected between 1978 and 2001 were analyzed to explain the lack of change in fertility and to examin...

INTRODUCTION HIV reduces fertility through biological and social pathways, and antiretroviral treatment (ART) can ameliorate these effects. In northern Malawi, ART has been available since 2007 and lifelong ART is offered to all pregnant or breastfeeding HIV-positive women. METHODS Using data from the Karonga Health and Demographic Surveillance Site in Malawi from 2005 to 2014, we used total ...

The global proteome of sperm and seminal plasma of fertile stallions was investigated to determine whether associations with relative in vivo fertility exist. Seven stallions at stud in a commercial breeding station were collected throughout the breeding season and bred to a total of 164 mares to determine conception rates. On three occasions during the breeding season, raw semen was obtained f...

In this paper we conduct descriptive aggregate analyses to revisit the relation between low and lowest-low period fertility on the one, and cohort fertility and key fertilityrelated behaviors—such as leaving the parental home, marriage and female labor force participation—on the other side. First, we identify a systematic pattern of lowest-low fertility that is characterized by a rapid delay of...

The global population is at a turning point. At the end of 2004, the majority of the world’s population is believed to live in countries or regions below-replacement fertility, and the earlier distinct fertility regimes, ‘developed’ and ‘developing’, are increasingly disappearing in global comparisons of fertility levels (Wilson 2001, 2004). Several aspects of this convergence towards low ferti...

Births According to provisional reports, an estimated 300,000 births occurred in the United States during December 1995. This was a decrease of 4 percent from the provisional number of births reported for December 1994 (314,000). The birth rate, 13.4 live births per 1,000 population, was 5 percent lower than the rate of 14.1 for December 1994. The fertility rate, 59.3 live births per 1,000 wome...

The aim of this paper is to understand recent observations of fertility, female employment, and participation rates in O.E.C.D. countries. These observations indicate that fertility rates are positively correlated with female employment ratios and participation rates across O.E.C.D. countries during the period 1985-1996. Moreover, the time series observations show that fertility rates are procy...
