Infertility Treatment Now and in the Future.

Treatment of infertility has evolved as understanding of reproduction has improved. Fertility promoting surgery still is performed and recent advances have broken new ground. Hormonal treatments to correct gonadal dysfunction have been developed, but multiple gestation continues to be a significant complication. Assisted reproductive technologies have improved such that in vitro fertilization and its variants increasingly are used to treat nearly all causes of infertility. Advances in assisted reproduction are of 2 types: (1) incremental optimization of existing techniques and (2) development of new, disruptive technologies. Artificial intelligence and stem cell technologies are poised to have impact in the near future.
