IVF Without Two Weeks of Injections? Inside IVM

Sunday, August 2, 2026Women's Health MelbourneView original

What if eggs could be collected before they mature and developed outside the body, potentially reducing the medications, time and physical burden involved in conventional IVF?


In this episode of Knocked Up, fertility specialist Dr Raelia Lew is joined by CREI fertility specialist Dr Violet Kieu to explore in vitro maturation, known as IVM.


Unlike conventional IVF, where hormone injections are used to mature eggs inside the ovaries before collection, IVM involves retrieving immature eggs and completing part of the maturation process in the laboratory.


Raelia and Violet take listeners inside the Melbourne IVF CAPA-IVM study, explaining how the procedure works, who may be suited to it and why researchers are particularly interested in its potential for patients with high egg numbers.
