We investigate two methods of measuring fitness in evolutionary games played among members of a finite population. Classical notions of stability account for the action of selection only, and use immediate reproductive gains as a measure of fitness. This classical interpretation of fitness is what we call reproductive fitness (RF), and is found in the early studies of evolutionary stability in ...

recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(art) (1). gradually, the important role of three-dimensional (3d) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).

OBJECTIVE To compare life satisfaction between women with successful or unsuccessful outcome after assisted reproductive treatment (ART) by taking into account the time since the last ART. DESIGN Cohort study. SETTING Tertiary hospital. PATIENTS A total of 987 consecutive women who had undergone ART during 1996-2007 were invited and altogether 505 women participated in the study. INTERV...

Research in the field of Ambient Assisted Living gained considerable momentum over the last decade and the diversity of existing applications is matched by a broad variety of implementation approaches. This paper takes a closer look at existing work in this field and provides a structured overview over state-ofthe-art implementation concepts.

Assisted reproductive technologies have generated a worldwide "reproductive revolution."' Latin America is no exception.2 Access to reproductive technology, and in vitro fertilization (IVF) in particular, can substantially benefit people's well-being. IVF is an assisted reproductive technology that involves fertilizing female eggs with sperm outside of a woman's body in a laboratory. In IVF, th...

background: approximately one percent of current live births of the world are conceived via assisted reproductive technologies (art). objective:  the purpose of this study was to compare the developmental status of children born through assisted and natural conceptions at the age of five years. materials and methods:  in a retrospective cohort study, developmental status of 5 years old children...

cumulative embryo score (ces) is one of the many embryo scoring methods which have been developed to help clinicians to transfer high quality embryos and predict pregnancy rate in assisted reproductive techniques (art) cycles. regarding the existing difference in ces calculation this study was done to compare two methods in order to determine the more practical and preferable one. in a retrospe...

The use of assisted reproductive technology is increasing rapidly. Research, although sparse, has resulted in inconsistent findings as to the developmental prognosis for infants conceived by assisted reproductive techniques such as in vitro fertilization and the use of fertility drugs. In the present study, the authors compared twins who were spontaneously conceived with those who were conceive...
