The scientific program of the first annual meeting of the American Society for Reproductive Medicine (ASRM) of the new millennium was comprehensive, informative and covered most of the current issues in the expanding field of reproductive medicine. The meeting was characterized by many clinical updates, new discoveries in clinical and basic research and significant societal issues in the practi...
The effect of myomas on reproductive outcome has been the subject of many studies; however, a definitive answer is still missing. Therefore, the authors have tried to outline some guidelines for the management of women who have uterine myomas and desire to conceive. The location and size of the myomas are the two parameters that influence the success of a future pregnancy. Subserosal myomas see...
Various assisted reproductive techniques have been developed and refined to obtain a large number of offspring from genetically superior animals or obtain offspring from infertile (or subfertile) animals. The embryo transfer is one assisted reproductive technique developed well, aimed at increased productivity of selected females, disease control, importation and exportation of livestock, rapid...
Heterotopic pregnancy occurs when intrauterine and ectopic pregnancy are concomitant; overall rate rises from 1/30.000 to 1.5/1000 in assisted reproductive technology pregnancies. HIV (human immunodeficiency virus) patients are at increased risk of heterotopic pregnancies due to the greater frequency of assisted reproductive technology and pelvic inflammatory disease. We report the first case o...
Scholars of differing political affiliation and the President's Council on Bioethics have called for regulation of assisted reproductive technology (ART) that would emulate many aspects of the regulatory system of the United Kingdom, in particular that of the Human Fertilisation and Embryology Authority. Specifically, scholars and the Council have argued that research in the U.S. involving game...
OBJECTIVE To characterize the prevalence of objections to assisted reproductive technologies among obstetrician-gynecologists. METHODS We conducted a national probability sample mail survey of 1,800 practicing U.S. ob-gyns. Criterion variables were whether physicians object to artificial insemination or in vitro fertilization. We also presented seven patient scenarios and asked respondents if...
Background: Understanding the physiological and psycho-social effects of pregnancy through Assisted Reproductive Technologies (ARTs) will enable health care providers to identify and treat any adverse outcomes, and provide support to women seeking fertility treatments. The aim of this paper was to review studies describing prenatal care in pregnancy through ARTs. Methods: A systematic search o...
Assisted reproductive technology (ART), such as donor-assisted insemination (DI) relying on anonymous sperm donors, has been available since the 1940s, and it is assumed that tens of thousands of children throughout the world have been born through these procedures. Although anonymous DI has been occurring in Japan since the late 1940s, the use of egg donation has been a more recent development...
Twins and higher–order multiple pregnancies account for approximately 3% of all gestations in the United States (Ananth et al, 2004) and seem to be stabilized since 2006 after a dramatically increase since the beginning of the 1970s (Vayssière et al, 2011). There are two main causes for the change in the rate of multiple pregnancies: advanced maternal age and use of assisted reproductive techni...
