Sperm donation question

Lisa

Hi there, I am 35 and have conceived naturally once before. All my tests/ultrasounds have come back normal. Just wanting to get an idea of what to expect when seeing my fertility doctor in regards to using donor sperm. I just assumed I would be doing IVF but now I'm thinking they may push for IUI, any ideas???Also, how successful is IUI? I'm kind of hoping to do IVF to better my chances. Bit stressed. Thanks
