Inability of programming the start of gonadotrophin stimulation in GnRH antagonist cycles and of minimizing weekend retrieval of oocytes is a major impediment to the widespread implementation of GnRH antagonist protocol in infertility clinics.
Several attempts have been made to bring the schedule of egg retrievals in a GnRH antagonist protocol under improved control. Scheduling of cycles is common practice in order to avoid weekend retrievals and equally distribute the workload throughout the week. A planned distribution of the workload avoids excessive incubator door openings and their negative impact on embryo development. It also helps with better work schedules for embryology and nursing staff and avoids unplanned work that may result in loss of concentration and reduced efficiency.
Two different pre-treatment regimens in GnRH-antagonist to be compared, Combined oral contraceptive pill versus oral estradiol Valerate.
AIM OF THE WORK:
The aim of work of the current study was to study different pre-treatment scheduling options in antagonist protocol and their impact on outcomes of IVF/ICSI.
