We examine the demographic correlates of paternity confidence, or men's assessment of the likelihood that they are the genetic father of a particular child. Evolutionary theory predicts that men will provide less parental investment for putative genetic offspring who are unlikely to be their actual offspring, but confidence of paternity has not been as extensively examined as its importance wou...

BACKGROUND Coffee and caffeine have been inconsistently found to be associated with increased risk of clinical miscarriage-a potentially important association given the high prevalence of exposure. METHODS Women were recruited before or early in pregnancy and interviewed regarding sources of caffeine, including assessment of changes over the perinatal period. We identified 2407 clinically-rec...

OBJECTIVES The most common indication for treatment of varicocele is still male subfertility. The aim of this study was to explore the effect of infertility duration on semen parameters and spontaneous pregnancy rate after varicocelectomy. MATERIALS AND METHODS The medical records of 183 infertile patients with clinical varicocele were retrospectively reviewed. The patients were divided into ...

Spontaneous abortion is the most common complication of pregnancy. Several lines of evidence indicate that immunologic effector cells may play a role in the pathogenesis of idiopathic repetitive abortions. Leukocytes form a substantial proportion of stromal cells in decidua and the endometrial granulated lymphocytes (eGL) is the predominant decidual leukocyte population in the first trimester o...

objective herpes simplex virus (hsv) infection during pregnancy may lead to fetal loss. the aim of this study was to explore the infection rate of hsv type 1 and 2 infection associated with spontaneous abortion in a pilot case-control study in two cities of iran in 2010. patients and methods placenta and curettage samples from 35 healthy full term neonates and 35 cases of spontaneous abortion w...

BACKGROUND We aimed to compare reproductive outcomes following ectopic pregnancy (EP) versus livebirth, miscarriage, or termination in a first pregnancy. METHODS AND FINDINGS A retrospective cohort study design was used. Scottish national data on all women whose first pregnancy occurred between 1981 and 2000 were linked to records of a subsequent pregnancy. The exposed cohort comprised women ...

OBJECTIVES Spontaneous abortion is one of the most important complications of pregnancy with short and long adverse psychological effects on women. This study assesses the implications of a spontaneous abortion history has on women's psychiatric symptoms and pregnancy distress in subsequent pregnancy less than one years after spontaneous abortion. METHODS A case-control study was conducted on...

Unintended pregnancy can carry serious consequences for women and their families. We estimate the incidence of pregnancy by intention status and outcome at worldwide, regional, and subregional levels for 2008, and we assess recent trends since 1995. Numbers of births are based on United Nations estimates. Induced abortions are estimated by projecting from recent trends. A model-based approach i...

Live births, induced abortions, and miscarriages/stillbirths are usually examined separately. This article combines the three outcomes to focus on pregnancy in Canada from 1974 to 1992. An estimated 525,100 pregnancies ended in Canada during 1992. While this was a substantial increase from 438,300 in 1974, the pregnancy rate in 1992-77 pregnancies per 1,000 women aged 15 to 44-was actually lowe...

Periodic estimation of the incidence of global unintended pregnancy can help demonstrate the need for and impact of family planning programs. We draw upon multiple sources of data to estimate pregnancy incidence by intention status and outcome at worldwide, regional, and subregional levels in 2012 and to assess recent trends using previously published estimates for 2008 and 1995. We find that 2...
