Infertility, Female Clinical Trial
Official title:
Evaluation of Patients of Failed in Vitro Fertilization Cycle: Prospective Cohort Study
Current in-vitro fertilization (IVF) consumers are enjoying better success rates than early seekers, but only about a quarter of IVF cycles result in a live birth and many patients remain infertile after multiple IVF attempts. Recurrent IVF failure is distressing to patients and challenging to clinicians. Despite interventions have been proposed to improve IVF outcome after couples of failed cycles, only a few of which are evidence based. Laparoscopy, as the gold standard for the evaluation of the pelvis, was used to be the routine procedure for many reproductive physicians. It provides information on endometriosis, tubal patency, and pelvic adhesions and a chance to fix these lesions concurrently.

Recurrent IVF failure is distressing to patients and challenging to clinicians. Despite interventions have been proposed to improve IVF outcome after couples of failed cycles, only a few of which are evidence based. Laparoscopy, as the gold standard for the evaluation of the pelvis, was used to be the routine procedure for many reproductive physicians. It provides information on endometriosis, tubal patency, and pelvic adhesions and a chance to fix these lesions concurrently. The role of laparoscopy, especially in women whose normal screening tests suggest that pelvic pathology seem to be unlikely. However, sometimes a "normal" pelvic imaging can be misleading, since HSG or ultrasonography cannot to rule out hydrosalpinx and endometriosis completely. Furthermore, it has been shown that HSG is insufficient for predicting tubal potency for some patients with risk of pelvic adhesions, with a sensitivity between 0.0% and83% and specificity between 50% and 90%. When initial IVF treatments fail, can we offer the couples to choose additional cycle of IVF instead of evaluation of the potential peritoneal factor? In cases of otherwise so called "Unexplained infertility", the investigation cannot be considered complete until laparoscopy has been performed. ;
