Aspiration Off Eggs
Once the ovarian follicles have achieved an adequate size and stage of development, a trigger injection is given to induce final maturation of the eggs. The timing of this injection is very important to the outcomes of your in vitro fertilization (IVF) cycle and needs to be precise. An egg retrieval procedure is then scheduled for 36 hours following this injection. An egg retrieval takes place in a special procedure room. This procedure takes approximately 30 minutes and during that time, all ovarian follicles are drained and fluid is sent to the lab to find eggs.
Eggs are drawn out of follicles with gentle suction from the help of ultrasound images and a special needle. An IV catheter is placed and will be used for sedation and pain medication during the procedure. You may wake up with some discomfort, but this can be alleviated with medications in the recovery area.
Male partners will be scheduled to collect a fresh semen sample on the day of egg retrieval. If needed, the sample frozen for back up can be thawed and used to inseminate eggs.
