Thanks for the D2D. Both methods can be effective, but a lot depends on your medical condition and the causes of your subfertility in the first place.
IUI is relatively simple, less invasive, less costly and less time-consuming, but the success rates are lower. Certain existing conditions make IUI less favourable, for example if your husband’s sperm count and quality are low, or if you have 1 or both fallopian tubes blocked.
IVF gives you the best chance of getting pregnant, but it demands more of your time and effort, is more invasive and costly, and most ladies find it more stressful.
You and your spouse should discuss this issue with your fertility doctor in order to understand and select the type of treatment that best suits you.
