• Resumen

  • Since the first in vitro fertilization infant was born in England in 1978, the practice of assisted reproductive technology (ART) has steadily increased as the technology and success rates have improved. The incidence of multiple gestations has also increased, primarily owing to the practice of transferring multiple embryos during an ART cycle. Guidelines for unfertility clinics have been outlined, along with strategies to limit teh number of embryos transferred /depending on the age of the patient) to achieve a lower risk of multiple borths. Since 1997, a decrease has ocurred in the number of embryos trasferred and the percentage of gestations with three or more fetuses, accompanied by a steady invrease in the percentage of live births per cycle.
