i agree with Leasha - contact the clinics directly. you'll need to meet with a GP or gyne to get a referral to the clinic - at that point, they should be able to confirm your diagnosis. you've not mentioned what that diagnosis is, but the diagnosis can make a huge difference to what sort of treatment you're need. Leasha and i both have PCOS - so are technically "subfertile" not infertile - we can ovulate just need a bit of extra help to get there! if your diagnosis is something like this, you may only require IUI (insemination - with help to ovulate) as opposed to full IVF.

either path is going to be emotionally, physically, and financially draining. i would speak to a gp first about what options you have, and get them to refer you to a fertility clinic. check out their websites about sperm donors etc. something to keep in mind - sperm donors are few and far between if you get an Au donor - not sure about buying in sperm from overseas - so there can be a significant wait to access donor sperm. policy will also vary from state to state, clinic to clinic. do your research, contact the clinics and talk to them about your circumstances - they're generally pretty open about costs and associated processes.
