Hi Lotusflower
1. My first child, I used Dr. Clement Chan in Central - both for all the Clomid & IUI cycles (which were useless) and my first IVF cycle (which worked). The good point is that he did get us pregnant. The bad point is that I felt he was quite pushy, especially trying to get me "signed up" for a C-section when I was only 6 weeks pregnant. He was also more drug-happy than other doctors, esp in early pregnancy. But, ultimately, he got results.
2. My second IVF cycle was with Dr. Tang Oi-Shan at HK Sanitorium. I felt she was more relaxed, allowed me to ovulate naturally, and didn't ask me to have bed rest of anything. This approach also worked. For both cycles, we used Sanitorium's embryoloists, who are known as being among the best in Asia.
3. I can't remember the exact costs right now -- after all, I concieved my first child almost 3 years ago -- but it was alot.
4. There were all sorts of male problems, including a physical issue that we tried to fix with surgery, plus lifestyle problems -- just generally bad sperm (low counts, low motility, etc). Anyway, all of that initial treatment did no good. Ultimately, with male problems, IVF is usually the only way to go. I had a friend with a similar treatment - her partner had almost "zero sperm." And only IVF would do it.
5. The first IVF cycle took about 3 months, all told. First, you have a check-up. Then the doctor gives you drugs to stimulate your egg production. Then, when you are ready to ovulate, they extract the eggs -- this is the most involved part. (I did mine under general anesthetic). In my case, we decided to freeze the embryos and wait a month. When I was ready to ovulate again, he placed the embryos in my uterine lining, which was much easier than part 1. (I did it with no anesthetic). Then the two-week wait.
My second cycle was easier, since I had leftover frozen embryos. Basically, they just track ovulation and transfer put the embryos in. This took one month in total.
I know you say you only want to do this once -- don't we all! But remember that there are no guarantees -- and the chances are that you might have to go through it more than once. The Sanitorium nurse said I was both very fertile and very lucky to have two viable pregnancies from only one egg extraction. So you do have to hedge your expectations.
