Any fertility specialist do IUI on a single woman in MY.

Hi gals, Do you know if there is any fertility specialist do IUI on a single woman in MY (Malaysia)? I have contacted some centres and it seems that there is no fertility specialist do IUI on a single woman (not marry) who use sperm donor. I wonder if this can be done in Singapore. Kindly list down the centre name here if you come to know any of them. Thanks in advance.
