Fertility preservation is feasible in the majority of men. Herein, we review the reproductive toxicities of commonly encountered clinical threats to male fertility, including cancer, radiotherapy, chemotherapy, surgery, and nonmalignant diseases treated with immunosuppression. Other scenarios, in which fertility preservation may be considered, such as Klinefelter syndrome, acute testicular inju...

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...

BACKGROUND Fertility is one of the three principal components of population dynamics. High fertility and rapid population growth exert negative influences on economic and social development. This study was aimed to estimate the level and trends of fertility among (15-49 years) old women in kersa demographic surveillance and health research center, kersa district Eastern Ethiopia. METHODS The ...

BACKGROUND Most of what we know about fertility decline in the United States comes from aggregate (often state or county level) data sources. It is difficult to identify variation in fertility change across socio-economic classes in such data, although understanding such variation would provide deeper insight into the history of the fertility transition. OBJECTIVE We use rich micro-level data t...

BEFORE EXPLAINING why we disagree with the views expressed in the two preceding comments, we summarize briefly the purpose and main features of the method described in Bongaarts and Feeney (1998). Our study set out to address a well-known flaw in the total fertility rate, the most widely used measure of period fertility. The TFR is affected by changes in the timing of childbearing. In years whe...

Background Central to the study of populations, and therefore to the analysis of the development of countries undergoing major transitions, is the calculation of fertility patterns and their dependence on different variables such as age, education, and socio-economic status. Most epidemiological research on these matters rely on the often unjustified assumption of (generalised) linearity, or al...

BACKGROUND While recent studies have indicated that fertility has remained high in Uganda, no systematic attempt has been made to identify the factors responsible for this persistent trend and to quantify these factors. This paper uses the Uganda Demographic and Health Surveys (UDHS) of 2006 and 2011, to examine the contribution contraceptive use, marriage and postpartum infecundability on one ...
