Infertility in advanced reproductive age. Results of in vitro fertilization and embryo transfer according to the woman's age.

: The Authors discuss the phenomenon of the gradual decline of a woman's fecundability with the passing of time and particularly the potential causes of infertility in advanced reproductive age and the most efficient therapeutic management. They conclude that more advanced aided conception techniques such as IVF/ET, GIFT, ZIFT and IPI should be preferred to surgery for women over a certain age, especially where the infertility problem is of more than five years standing, and discuss the effect of the subject's age on the various stimulation techniques available. The Authors then report their experience with IVF/ET in 806 induction cycles using five different stimulation protocols at the Foundation for Studies on Human Reproduction in Palermo.
