Analysis of the 1993 National Demographic Survey in the Philippines has uncovered regional variations in fertility-related behavior. The total fertility rate ranged from 2.8 in Manila to 5.9 in Bicol and averaged 4.1 for the entire country, but contraceptive prevalence rates were not highly correlated with total fertility (Manila showed the fifth highest prevalence, and Bicol the fifth lowest)...

BACKGROUND Studies from different contexts worldwide indicate that HIV positive patients manifest high-risk sexual behavior characterized by fertility intentions, multiple sexual partners, non-use of contraceptives and non-disclosure of HIV status to their sex partners. The objective was to analyze fertility desires among persons living with HIV at a treatment centre in Kabale Hospital, Southwe...

The role of religion in explaining fertility differences is often overlooked in demographic studies, particularly in Western Europe, where there has been a substantial decline in institutional forms of religious adherence. The current study explores the changing relationships between religion and childbearing in Britain, France and the Netherlands. Using data from the Generations and Gender Pro...

The male-specific Fruitless proteins (FruM) act to establish the potential for male courtship behavior in Drosophila melanogaster and are expressed in small groups of neurons throughout the nervous system. We screened ∼1000 GAL4 lines, using assays for general courtship, male-male interactions, and male fertility to determine the phenotypes resulting from the GAL4-driven inhibition of FruM expr...

One of the major demographic changes during the past 200 years is the emergence of the twochild norm as part of the creation of the modern family. While we know a great deal about the timing of the fertility transition in different regions, we know much less about specific features and causes. The aim of this paper is to use longitudinal micro-level data for seven local populations in Europe an...

Background: Uterine leiomyomas (fibroids) are now known to be highly variable in their clinical behavior and biologic basis. However, the approach to leiomyomas and their effect on fertility, miscarriage and pregnancy complications has been based on location alone. Materials and Methods: This talk with bring together published information on the effect of leiomyomas on reproductive performance ...

Background: Green tea is a popular type of tea that is made of unfermented tea leaves. Green tea has been used for thousands of years by people in Eastern countries for a variety of health reasons. One of the primary benefits of Green Tea in regard to fertility is not in what it contains, but rather in what it does not contain. Materials and Methods: In the present study attempts to investigate...

There are similarities and differences in marriage and fertility behavior between early North American societies and their modern counterparts. This paper investigates the quantitative importance of differential fecundity, assortative matching, and marriage market search frictions in affecting marriage and fertility behavior in a Catholic society, 18 century Quebec. The model may provide an exp...

BACKGROUND Successful reproductive efforts require the establishment of a situation favorable for reproduction that requires integration of both behavior and internal physiological events. TR4 nuclear receptor is known to be involved in male fertility via controlling spermatogenesis, yet its roles in regulating other biological events related to reproduction have not been completely revealed. ...

Past research shows that men respond to women differently depending on where women are in their ovulatory cycle. But what leads men to treat ovulating women differently? We propose that the ovulatory cycle alters women's flirting behavior. We tested this hypothesis in an experiment in which women interacted with different types of men at different points in their cycle. Results revealed that wo...
