This review critically evaluates the current trends of male reproductive health problems in relation to semen quality. Increasing trend in male reproductive disorders observed in recent years, are principally found to associate with lifestyle and environmental factors. Lifestyle-allied diseases

Abstract: Opinions on reproductive health education at the onset of puberty at present were studied by using a structured questionnaire consisting of 13 questions with a view to know their conception about it. A total of 800 male students were randomly selected of which 400 were from two public

The discovery in the mid-1970s that occupational exposures to pesticides could diminish or destroy the fertility of workers sparked concern about the effects of hazardous substances on male reproductive health. More recently, there is evidence that sperm quantity and quality may have declined

the effects of endocrine-disrupting chemicals on human semen quality and assisted reproduction outcome. Abstract Endocrine-disrupting chemicals are substances present in the environment that can interfere with normal hormonal bal-ance and thus exert potentially adverse health effects on the human organism

The amount of research into endocrine disruption has exploded over the past decade and a re-evaluation of the state of research in this area is timely. There are debates about whether human male reproductive health is really declining and whether endocrine disrupting chemicals play any role

selection of households, with an individual response rate of 78%. All men participated in a 20-minute computer-assisted telephone interview exploring general and reproductive health. Associations between male reproductive health disorders and lifestyle and biomedical factors were analysed using multivariate

This paper reports measures of preference parameters relating to risk tolerance, time preference, and intertemporal substitution. These measures are based on survey responses to hypothetical situations constructed using an economic theorist's concept of the underlying parameters. The individual measures of preference parameters display heterogeneity. Estimated risk tolerance and the elasticity of intertemporal substitution are essentially uncorrelated across individuals. Measured risk tolerance is positively related to risky behaviors, including smoking, drinking, failing to have insurance, and holding stocks rather than Treasury bills. These relationships are both statistically and quantitatively significant, although measured risk tolerance explains only a small fraction of the variation of the studied behaviors.
