IVF ladies

To all the ladies who have undergone IVF, about how long start to your first I guess I would say procedure? Transfer? I have been TTC for almost 2 years now... One of those years with medicated cycles. I've had 4 failed IUIs and I am just tired of the constant bad news and even though I am able to do two more IUIs I would rather move to IVF. I have PCOS and damaged tubes and my dr suspects I also have endometriosis. DH has very poor morphology as well, only about 3% so the odds are really stacked against us. Any advice about a timeline would be so appreciated! Thanks ladies!!!
