If you have unexplained infertility, what are your chances of ultimately having a baby—either through infertility treatment or natural conception? We talk with Dr. Denis Vaughan, a board-certified Reproductive Endocrinologist at Boston IVF and a Clinical Instructor at Harvard Medical School. He was the principal investigator on the study "Long-term reproductive outcomes in patients with unexplained infertility". In this episode, we cover:What year was the original FASTT trial and what were the findings?What is unexplained infertility and how common is it?Did most of the women try to conceive after the original FASTT trial?How did the women who agree to participate in this follow-up study compare to the original FASTT participants? Was there a difference between those who participated in the follow-up and those who did not?What percentage of the women were successful at conception with IUI? IVF? Natural conception?What percentage tried to conceive with donor egg?What percentage adopted?If the woman had conceived via fertility treatment in the original FASTT trial is she more likely to conceive successfully in the future?Some speculate that a significant proportion of unexplained infertility is due to un-diagnosed endometriosis. Did this follow-up study shed light on that question?Did many of the women after the original FASTT study receive a more definitive diagnosis of why they were not able to conceive?What did the study show about patient satisfaction with their family building process and ultimate family size?What did we learn about conception with unexplained infertility as a result of the follow-up to the FASTT study?This podcast is produced  by www.CreatingaFamily.org.
