How to Prepare for Egg Retrieval

Preparing for egg retrieval generally involves stimulation injections per the doctor's plan, periodic monitoring with ultrasound and blood tests, and strictly following pre-retrieval instructions. Because stimulation plan details vary by individual, you should primarily follow the specific instructions from your treating doctor.

Key Takeaways

Egg retrieval usually starts with a stimulation phase using injectable medication per an individualized plan set by the doctor.
During stimulation, ultrasound and blood tests are done periodically to monitor follicle growth.
Follow the doctor's instructions strictly, such as injection timing and pre-retrieval instructions.
Ask your doctor about risks and symptoms to watch for during the stimulation phase.

Egg retrieval is a step in the IVF/ICSI process or egg freezing, starting with ovarian stimulation using hormone injections per an individualized plan set by the doctor, so that multiple follicles grow together.

During the stimulation phase, the doctor schedules follow-up ultrasounds and blood tests periodically to assess follicle growth and adjust the medication plan as appropriate. When the follicles are ready, the doctor schedules the retrieval date and gives specific preparation instructions, such as fasting times before the procedure.

Because the stimulation plan and preparation details vary by individual based on medication type and body response, you should closely follow the specific instructions from your treating doctor.
