Background: Nearly 0.6%–7% of patients undergoing in vitro fertilization embryo transfer (IVF ET) will not be able to yield any oocyte despite successful ovarian stimulation and this condition is called as empty follicular syndrome (EFS). EFS is a dreadful situation for clinicians as well as patients, seems to be an unavoidable clinical condition despite a proper ovarian stimulation. Materials and Methods: This was a retrospective observational study conducted at a tertiary hospital; 1103 patients who underwent IVF ET between January 2016 and May 2017 were included in the study. Study Outcome: To estimate the incidence of empty follicle syndrome (EFS) and to study the associated factors. Results: There were 53 (4.8%) cases of EFS out of 1103 cycles of IVF ET; 43 (3.9%) cases were false EFS and 10 (0.9%) cases were genuine EFS. Mean age of EFS group and oocyte retrieved group was 30.17 years and 29.12 years respectively. Recurrence rate of EFS during the next IVF cycle was 36.8%. Decreased ovarian reserve was associated with an increased chance of EFS (54.7%) with a recurrence rate as high as 57%. Conclusion: The incidence of EFS is not an uncommon clinical scenario; it depends upon ovarian reserve to a great extent. Young age is not immune for the occurrence of EFS as there is a similar incidence in comparatively younger age group in our study. EFS is seen in all etiological groups of infertility, but only respite is that there is a chance of about 63.2% oocyte retrieval during repeat IVF cycle.
