Male factor infertility affects 30%-50% of infertile couples worldwide, and there is an increasing interest in the optimal management of these patients. In studies comparing double and single intrauterine insemination (IUI), a trend towards higher pregnancy rates in couples with male factor infertility was observed. Therefore, we set out to perform a meta-analysis to examine the superiority of ...

Although infertility is an important public health problem, treatment can be expensive and resources are increasingly scarce. This study investigates possible inequalities in the use of medical services for fertility problems. We analysed data from a population-based survey for associations between socio-economic characteristics and help-seeking or use of services, to establish whether inequali...

Male-biased genes have drawn considerable attention due to their relatively rapid rates of interspecies diversification. These genes are often involved in processes related to reproductive behavior, sexual competition, and gametogenesis. Despite this trend toward rapid evolutionary change, many core molecular pathways underlying spermatogenesis are conserved between Drosophila melanogaster and ...

BACKGROUND In men, excess weight may be linked with altered testosterone, estradiol levels, poor semen quality and infertility. We investigated whether higher BMI among men is associated with infertility and if so, to what extent that effect might be mediated by altered sexual function. METHODS A retrospective cohort study of pregnancies from 1999 through 2005 based within the Norwegian Mothe...

A survey on opium use was earned out in Tinsukia district of upper Assam to assess the present prevalence and pattern of opium abuse and compared with earlier findings of the year 1981 (Baruah et al., 1995). A total of 75 addicts could be detected during the survey and 61 were interviewed using structured questionnaire. The results indicate significant decline in prevalence in opium use over th...

Background Infertility is a disease that results in the abnormal functioning of the male or female reproductive system. Systematic research planning on any subject, including infertility is in need of solid data regarding previous efforts in this field and to identify the gaps in the research. Objective The aim of this research is to study the thematic structure of articles related to inferti...

Introduction At a time when limiting family size has become of national interest, increasing numbers of married couples are moving in a different direction-to overcome infertility and conceive children. Reasonably reliable statistics indicate that approximately 3 .5 million couples, or nearly 15% of those of childrearing age, are subfertile. If one adds the cases of secondary infertility, in wh...

Background and aims: Infertility is one of the most important conditions in reproductive system and there is no reliable estimates for global prevalence of infertility. Therefore, knowing the prevalence of infertility is important and can be effective in decision making. Methods: We systematically reviewed all published papers in Medline database and Scopus (1988–2010). Univariate and multivar...
