The ART of Life: IVF or Child Adoption? This paper analyzes the effects of child adoption on the utilization of assisted reproductive technology (ART) in the US. Using state-level longitudinal data for 1999-2006, we show that ART use is responsive to changes in adoption markets. Controlling for state-specific fixed effects, the estimated elasticity of ART cycles performed with respect to child ...

INTRODUCTION This study is part of a longitudinal cohort undertaken in both women and men to describe live birth outcome after undergoing assisted reproductive technology (ART) treatment in a clinical setting. Another objective was to follow women and men living with children from other alternatives after ART, such as adoption. MATERIAL AND METHODS A total of 439 (80.5%) women and 423 (77.6%)...

Dear Editor: Upon reading the recently published article entitled “Adverse pregnancy outcomes with assisted reproductive technology in non-obese women with polycystic ovary syndrome: a case control study” [1], we were compelled to point out that the study design does not conform to the principles of a case-control study. The authors state that the aim of the study was to compare the prevalence ...

Advances in science have made possible the derivation of reproductively viable gametes in vitro from mice. The research on human cells suggests that in vitro gametogenesis ("IVG") with reproductive potential may one day be possible with humans. This technology would allow same-sex couples to have children who are biologically related to both of them; allow single individuals to procreate withou...

The world population is increasing at dramatic rates; therefore, the demand for meat and milk products will continue to grow (CAST, 1999). Consumers also are demanding a more uniform, higher quality, nutritious product at a low price, requiring producers to raise animals that meet these specific demands. Altering herd genetics is a slow and expensive process because of the limitation of having ...

There have been several reproductive technologies developed over the past several years. Although these technologies have great potential to improve productivity of beef and dairy operations, they have only been minimally used. The reproductive technologies that may offer great value include estrus synchronization, embryo transfer, in vitro fertilization (IVF), sex-sorted semen, and embryo spli...

In vitro gametogenesis raises new possibilities for reproductive and regenerative medicine as well as vexing policy challenges.

Assisted reproductive technologies (ART) are a collection of different techniques designed to help those who are infertile achieve a successful pregnancy [4]. The most popular technology currently in use is in vitro [5] fertilization [6] (IVF), but others include gamete intrafallopian transfer (GIFT), zygote intrafallopian transfer [7] (ZIFT), intrauterine insemination (IUI), and intracytoplasm...
