The egg retrieval procedure is also referred to as egg aspiration, or egg pickup.
In order to get sufficient eggs for the in vitro fertilization process, the woman is stimulated with injected medications using one of several IVF medication stimulation protocols to develop multiple follicles and egg development. The injections are usually done by the woman, or by her male partner.
The eggs develop in fluid filled structures in the ovaries called follicles. Each follicle can be seen and measured by ultrasound and contains one microscopic egg.
