Because of the implications for behavioral, social, and cultural evolution, reconstructions of the evolutionary history of human parturition are driven by twomain questions: First, when did childbirth become difficult? And second, does difficult childbirth have something to do with infant helplessness? Here we review the available evidence and consider answers to these questions. Although the d...

The aim of this paper is to provide a review of the emerging literature on the relationship between the experience of difficult childbirth and the development of post-traumatic stress disorder (PTSD). First, we discuss the criteria for diagnosis of PTSD and the implications that changes in these criteria over the past decade have had for women who experience a traumatic childbirth. Although the...

Childbirth is complicated in humans relative to other primates. Unlike the situation in great apes, human neonates are about the same size as the birth canal, making passage difficult. The birth mechanism (the series of rotations that the neonate must undergo to successfully negotiate its mother's birth canal) distinguishes humans not only from great apes, but also from lesser apes and monkeys....

Despite research and policy-making to address these problems, changing childbirth practices has proved to...

The risk that abortion may be correlated with subsequent mental disorders needs a careful assessment, in order to offer women full information when facing a difficult pregnancy. All research papers published between 1995 and 2011, were examined, to retrieve those assessing any correlation between abortion and subsequent mental problems. A total of 36 studies were retrieved, and six of them were...

A relatively large number of women in their 40s with high-density breasts, in which it can be difficult to detect lesions, are encountered in mammography cancer screenings in Japan. Here, we retrospectively investigated factors related to breast density. Two hundred women (40-49 years old) were examined at the screening center in our hospital. Multivariate analysis showed that factors such as s...

According to the World Health Organization, about half a million women die each year due to pregnancy or childbirth [1]. Over half of these women are African (53% in 1995), while the rest are Asian (42%) and to a lesser extent Latin American (4%). Less than 1% of maternal deaths occur in Europe or North America (see table). In order to offset the variations linked to population size or birth ra...
