Oocyte retrieval is a crucial step in Assisted Reproduction Technology (ART), involving the collection of eggs from ovarian follicles. A double-lumen aspiration needle enhances this procedure by allowing both follicular fluid aspiration and controlled flushing of culture media, improving oocyte recovery rates.

Under ultrasound guidance, the needle is inserted into the ovarian follicles. The first lumen is used for aspiration, drawing out the follicular fluid containing the oocyte, while the second lumen enables the injection of a flushing medium. This medium helps detach oocytes that may still be adhered to the follicle wall, increasing the chances of successful retrieval. Depending on the clinician’s preference, the flushing and aspiration can be performed simultaneously or intermittently.

This design ensures greater efficiency and precision, optimizing the number of viable oocytes collected while minimizing trauma to the ovarian tissue.
