Egg Freezing Cycle Explained in 5 Simple Steps (2022)
Egg freezing involves a 5-step process from birth control to egg retrieval. Patients typically complete two cycles, with 15-30 mature eggs recommended for optimal future fertility. The procedure includes hormonal stimulation, monitoring, and vitrification for long-term storage.
Key Takeaways
Birth Control for Synchronized Egg Growth
A 2-3 week birth control phase is used to synchronize follicle growth and schedule flexibility. This allows physicians to determine the optimal start date for ovarian stimulation and retrieval.
Hormonal Stimulation and Monitoring
Daily FSH/LH injections over 10-12 days stimulate egg development. Patients attend 6-9 monitoring appointments with ultrasounds and bloodwork to adjust medication dosages as needed.
Trigger Injection for Egg Maturation
Administered after stimulation, the trigger shot finalizes egg maturity. This critical step prepares eggs for retrieval, occurring 36 hours before the procedure.
Egg Retrieval Procedure Details
The 15-30 minute intra-vaginal retrieval is performed under IV sedation. Patients require a driver post-procedure and typically miss only one day of work.
Egg Freezing and Storage Recommendations
Vitrification freezes mature eggs in liquid nitrogen. Women under 37 should aim for 15-20 eggs, while those over 37 or with reduced ovarian reserve need 25-30 eggs for multiple future attempts.
