A Case of Empty Follicle Syndrome with Successful Oocyte Retrieval by Use of Recombinant Human Chorionic Gonadotropin / 대한산부인과학회지

It has been decades since the concept of empty follicle syndrome (EFS), in which no oocytes are retrieved in an in vitro fertilization and embryo transfer (IVF-ET) cycle, was introduced. The incidence of this syndrome in patients undergoing IVF-ET has been estimated to be about 0.6-7%. The use of recombinant human chorionic gonadotropin (r-hCG) can be a useful option for the EFS patients with previous failure of oocyte retrieval in IVF-ET cycles. We present a case of empty follicle syndrome with successful oocyte retrieval by the use of r-hCG.
