I went to the same 輔助生育中心 because i'm over 36 and have had a few miscarriages before and eager for some professional advice from this special field of assisted fertility. Out of my expectation, 2 months after the first consultation i got pregnant naturally. I've never did any iui, ivf ... etc. not even ovulation medicine nor hormone. I'll keep going there because i trust the doctor, and it was the doctor who encouraged me to try natural pregnancy instead of assisted pregnancy.
