Hi notsure,
All Fertility Clinics in WA have fertility specialists who work with PCOS. PCOS is a very common referral to a fertility clinic. The significant point in your post is that you are currently single and therefore would need sperm donation. If it is known sperm donation that you plan to do then all the clinics can assist you however if it the anonymous sperm donor pathway that you're contemplating then there are 3 clinics in Perth who could help:
Keogh Institute (DI only)
Concept Fertility Centre (Will do DI, or IVF using Donor Sperm).
Pivet Medical Centre (Will do DI or IVF using Donor Sperm)
If Keogh Institute have sperm supply for single women use then I would suggest you see Clinical Professor Bronwyn Stuckey who is an endocrinologist with expertise in PCOS and diabetes.
At Concept Fertility - Dr. Lucy Williams is well respected, works with PCOS and frequently treats single women.
Hope this narrows it down.
Best of luck.
