Assisted reproductive technology (ART) has revolutionized the management of subfertility as many couples who previously had no hope of achieving a pregnancy are able to do so. Several factors contribute to the successful outcome of assisted conception. The period of waiting for the pregnancy test after assisted conception could be very crucial to the patient. One outcome of assisted conception ...

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 ...

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 ...
