Transvaginal oocyte retrieval - Wikipedia
Transvaginal oocyte retrieval is more properly referred to as transvaginal ovum retrieval when the oocytes have matured into ova, as is normally the case in IVF. It can be also performed for egg donation, oocyte cryopreservation and other assisted reproduction technology such as ICSI.

Oocyte Retrieval - an overview | ScienceDirect Topics
Oocyte retrieval is a painful procedure that takes place under short-term general intravenous anesthesia or analgesia. Under ultrasound control, the collection needle passes through the vaginal wall into the ovary and follicular fluid containing the oocyte with surrounding cumulus cells is aspirated from the follicles (Toporcerová, 2016).
Approaches to oocyte retrieval for advanced reproductive …
Oocyte retrieval for in vitro maturation is effected by the interaction of the many choices that need to be made in planning for the procedure. The most difficult decision involves aspiration pressure or fluid flow rate and needle size.
