N2 - Purpose: To identify common and varying practice patterns used by in vitro fertilization (IVF) providers from a broadly distributed, worldwide survey. Specific information regarding clinical IVF practices involving the oocyte maturation triggering, oocyte retrieval and embryo transfer was elicited. Methods: This is an internet-based questionnaire study of IVF practices throughout the world. We used 26 multiple choice questions regarding common clinical practices. The data reported are weighted based on the number of IVF cycles performed at the specific IVF center, represented by a single respondent. Results: Surveys were completed from 359 centers in 71 countries throughout the world. The most common practice patterns (defined as ≥75 % of IVF cycles) identified included: use of human chorionic gonadotropin (hCG) for trigger with an antagonist protocol, no routine patient monitoring from hCG trigger to oocyte retrieval, timing oocyte retrieval 34-37 h following oocyte maturing trigger, use of a single lumen retrieval needle, no routine tests following oocyte retrieval prior to patient discharge and use of ultrasound assistance with embryo transfer. Conclusions: This is the largest and most diversely represented survey of specific IVF practices addressing oocyte maturation triggers, oocyte retrieval and embryo transfers. Several uniform practice patterns were identified that can be correlated with evidence-based medicine; however, we identified multiple variable practice patterns which is likely the result of the absence of definitive evidence to guide IVF practitioners. The results of this survey allow IVF providers to compare their specific practice patterns with those of a global diverse population of IVF providers.
