Predictability of the egg pick up (EPU) date is of great importance for patients attending satellite clinics. Predictable EPU day allows patients and clinicians to coordinate IVF treatment cycles through the satellite clinics while minimising the time and financial burden of travelling into metropolitan cities for ongoing treatment. This was a retrospective cohort analysis of 1,172 agonist and antagonist treatment cycles conducted at two satellite clinics. Both clinics have an established EPU window of days 13 to 15 after commencement of stimulation. Data illustrated that antagonist cycles have a high proportion of patient’s requiring transfer to metropolitan clinics for EPU, with 3.6% of agonist cycle patients requiring transfer in comparison to 23.7% of antagonist cycle patients. Both groups showed a majority of EPU occurring within the day 13 to 15 window (72.8% agonist group, 62.2% antagonist group). However a higher proportion of antagonist cycles occurred outside the EPU window (27.2% vs 37.8%).

The results for this project are currently being prepared for publication.
