Infertility in the third millennium: implications for the individual, family and society: condensed meeting report from the Bertarelli Foundation's second global conference.

Primary infertility is a key issue in the developed world, while the developing world has high rates of secondary infertility. The impact of HIV/AIDS on fertility is insufficiently explored. One of the most important barriers to access to infertility treatment is cost; at the same time the role of social and cultural factors in restricting access should not be underestimated. IVF has become the standard therapy for female infertility, and ICSI for infertility of the male partner. However, the use of these therapies should not be initiated without a thorough investigation and, whenever possible, individual diagnosis of the underlying causes of infertility. Multiple gestation remains one of the most challenging and controversial issues in the treatment of infertility. Current IVF practices are often blamed for this; in this respect, attention should also be focused on the role of ovarian stimulation in ovulation induction. National guidelines and national registries for assisted reproductive technology (ART) are becoming more widespread and are expected to play an important role in promoting best practice in ART in the future.
