Background: Study question: what is the effect of advanced aged in pregnant women using assisted reproductive technology on the rate of miscarriages? Summary answer: the advanced age effects on the rate of miscarriages. What is known already: It is well known that miscarriage risk increases with age. The proportion of women giving birth after 35 years of age has risen considerably in developing...

BACKGROUND Older mothers are becoming more common in Japan. One reason for this is the widespread use of assisted reproductive technology (ART). This study assesses the relationship between maternal age and the risk of birth defects after ART. METHODS Nationwide data on ART between 2004 and 2010 in Japan were analyzed. Diseases that were classified as code Q00-Q99 (ie, congenital malformation...

PURPOSE The recent trends of multiple births (MBs) conceived by assisted reproductive technology (ART) in Korea were analyzed as well as the relationship with maternal age, especially advanced maternal age. METHODS Data were obtained from the Korean Statistical Information Service and annual ART reports from the ART committee of the Korean Society of Obstetrics and Gynecology. RESULTS MBs i...

BACKGROUND Maternal race/ethnicity, age, and socioeconomic status (SES) are important factors determining birth outcome. Previous studies have demonstrated that, teenagers, and mothers with advanced maternal age (AMA), and Black/Non-Hispanic race/ethnicity can independently increase the risk for a poor pregnancy outcome. Similarly, public insurance has been associated with suboptimal health out...

BACKGROUND We hypothesized that hemodynamic adaptations related to pregnancy and ageing might be associated with differences in blood pressure levels during pregnancy between younger and older women. This might partly explain the increased risk of gestational hypertensive disorders with advanced maternal age. We examined the associations of maternal age with systolic and diastolic blood pressur...

PURPOSE Children born to older parents are at greater risk for genetic abnormalities, such as Down syndrome. The influence of maternal age on Down syndrome is well established but little is known about the genetic consequences of advanced paternal age. MATERIALS AND METHODS Data on the incidence of Down syndrome from 1983 to 1997 (3,419 cases) were obtained from the New York State Department ...

background: human fertility has been declined all over the world. advanced women’s age is one of the most important factors in determining the success of reproduction and ageing has negative impact on art outcome and advanced female age decreases the chance of live birth rates achieved using art, especially after 40 years of age. objective: to evaluate art outcomes regarding to pregnancy, abort...
