Fertility in Norwegian women: Results from a population-based health survey

Abstract

Fertility problems were quite common, and have increased in younger age groups, though seemingly fewer women remained childless past their reproductive age in the youngest age group.

Epidemiologic study of infertility: Report of the hospital centre of St. John, Porto

“…Interestingly, higher levels of infertility were observed among women with higher levels of education, with the cultural level having been involved with the decision to become pregnant later. 29 These findings are different from the values found in a Portuguese epidemiological study that showed that the majority of infertile women have four or less years of education. 3 The observation that most of the infertile women (83%) did not smoke and that of those who smoke 45% consumed less than 10 cigarettes per day clearly indicates that women are aware of the pernicious effects of smoke.…”

“…The negative impact on fertility is the same reported to cigarette smoke. 24,29 This finding suggests that women need to find a recreational consumption that instead of smoking is being directed to alcohol consumption.

Self-Reported Infertility Among Male and Female Veterans Serving During Operation Enduring Freedom/Operation Iraqi Freedom

Childhood social hardships and fertility: a prospective cohort study

“…A population-based study of Scotland found a somewhat higher risk of infertility in those with both high and low levels of education, but no relationship with social deprivation,[6] while a Norwegian study found higher levels of involuntary childlessness with higher education, and reduced levels among those were manual workers. [7] However, a study of the Danish population found no difference in lifetime prevalence of infertility by social class[3]. …”
