US Guided Oocyte Aspiration
This procedure is performed with the patient under conscious sedation. As seen in this video the physician uses ultrasound to guide the aspiration needle inside each follicle. Negative pressure is applied by a vacuum pump and the resulting fluid is captured in tubes that are passed to the laboratory. In some occasions, flushing with culture media is required for the extraction of the oocyte from the follicle or the aspiration system.
