Oocyte Retrieval in IVM

Abstract

Transvaginal oocyte retrieval during assisted reproductive technologies (ARTs) was first introduced in 1981, replacing both surgical egg collection and laparoscopic retrieval but also previous different approaches such as the transurethral ultrasound-guided route. It is well known that the number of oocytes retrieved depends on many factors: type of aspiration needle (wide or narrow bore or single or double channel), aspiration pressure, follicular flushing, timing of HCG triggering, and experience and skills of the surgeon.
