Assisted reproductive technology (ART) encompasses all medical intervention used to assist people becoming parents, mainly but not solely as a result of infertility. In vitro fertilisation (IVF) is the cornerstone of ART. It involves stimulating the ovaries, retrieving and culturing oocytes which are then inseminated with capacitated spermatozoa. The embryo is cultured and transferred into the ...

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: FIVCAT.NET is the registry of human assisted reproductive techniques (ART) in Catalunya to which all authorised centres are obliged to declare their activities. The Background of the present study is to describe the data on effectiveness of the ART in Catalunya over the period 2001-2005 and to compare our findings with other similar registries. Materials and Methods: The data were o...

As assisted reproductive technology (ART) methods become the mainstream of infertility treatment, it has become even more critical to reassess its safety. Following the results of a study published by the Robinson Institute in the New England Journal of Medicine, the risk of ART, especially intracytoplasmic sperm injection (ICSI), has never been so closely scrutinized. This paper traces the ori...

Understanding human pre-implantation development has important implications for assisted reproductive technology (ART) and for human embryonic stem cell (hESC)-based therapies. Owing to limited resources, the cellular and molecular mechanisms governing this early stage of human development are poorly understood. Nonetheless, recent advances in non-invasive imaging techniques and molecular and g...

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...

Background: To investigate whether endometrial volume on the day of HCG (human chorionic gonadotropin) administration is a predictor of ART (assisted reproductive outcome) outcome Materials and Methods: Two hundred and seven patients in ART cycle were included in this prospective study; In order to evaluate endometrial volume and its relationship to ART outcome. Endometrial volume obtained from...
