Patients often ask: What is the success rate of artificial insemination? A: Generally 10-15%. Some people will continue to ask: Why is it so low? The reason is that, naturally, a couple with normal fertility has only about a 10% chance of becoming pregnant each month. Artificial insemination is a simulation of natural intercourse in which sperm is processed and injected into the uterine cavity. The improvement over the natural situation is that the sperm is optimized, the woman’s ovulation is determined, and the sperm does pass through the reproductive tract and enter the uterine cavity, but it is not clear whether the woman’s egg enters the fallopian tube and meets the sperm and is fertilized, and whether the fertilized egg can develop into a normal embryo and enter the uterine cavity for implantation. Therefore, the success rate of IUI is similar to the pregnancy rate of a normal couple under natural circumstances, which is only 10-15%. Some people may ask: If the rate is so low, I should go directly to IVF. Why can’t we just do IVF? Because artificial insemination is closer to natural conception, the fertilization of the eggs occurs naturally in the body, and this natural fertilization process is part of natural selection, resulting in healthier offspring, and at the same time, artificial insemination is less expensive, requires less drugs for the woman, does not require egg retrieval surgery, and has fewer complications. Therefore, artificial insemination is beneficial for both mother and child. Therefore, if you have the conditions for IUI (the woman’s fallopian tubes are open and the man’s sperm is not too small), you should do it first. If you have tried IUI several times and you are still not pregnant, or if your fallopian tubes are blocked or if the male partner has very little sperm and cannot do IUI, then you should consider IVF.
