IUI vs IVF: Engaging in infertility treatment may leave a couple wondering what kind of treatment they qualify for and whether or not they should pursue fertility treatments. Couples who struggle with conception can opt for two options to treat infertility: IUI and IVF. In IUI, fertilisation occurs inside the female’s body, whereas in IVF, fertilisation occurs outside the body. It is the primary distinction between IUI vs IVF.
Some people know one term better than the other, frequently without understanding the distinction or nature of either treatment. Discussing the unique situation with reproductive specialists is important, but one should also understand the comparison of IUI vs IVF.
A series of procedures known as IVF and IUI have the potential to result in pregnancy.
It is an infertility treatment; most couples can conceive after at least a year of trying an IVF. The mechanism of IVF involves the following steps:

Another procedure used to treat infertility is intrauterine insemination or IUI. It involves the introduction of prepared sperm directly into the uterus, the organ in which a baby develops, increasing the likelihood of conception. Artificial insemination is another term for this process. The mechanism of IUI involves the following steps:
IUI vs IVF: The likelihood of success rates for every patient depends on their specific diagnosis, medical history (and partner’s), age, and gender. However, one can compare by taking a look at general statistics. Let us know the success rate of both procedures:
Certain factors influence IVF success rates. They include age, ovarian reserve, infertility diagnosis, previous successful pregnancies, etc. Most patients can anticipate a success rate between 50% and 75% after just one IVF cycle. Patients may need two or three rounds of IVF when individual success rates are lower before conceiving successfully.
Age Under 35 years:
According to the Society for Reproductive Technology (SART), 55.6% of IVF-assisted live births occur in women under 35. There are 41.4% live births for every initial embryo transfer.
Ages between 35 and 37 years:
When using their eggs, IVF success rates for women between the ages of 35 and 37 are 40.8%.
Ages between 38 and 40 years:
The success rate for women in their 38th and 40th year is 26.8%, a significant decrease from the 35th and 37th years.
The individual success rate for IUI is 15-20% for each monthly attempt. With a cumulative success rate of 40 to 50%, doctors advise trying three to four rounds of IUI. The average monthly pregnancy rate in the general population is only one in five couples, or twenty percent per month. While they strive for the same success rates with IUI, many patients still require IVF treatment.
Age Under 35 years:
The success rate is between 13% for women in their early 35s or younger.
Age between 35 and 37 years:
The success rate of intrauterine insemination is typically 10% for women between 35 and 37 years.
Age between 38 years and beyond:
The success rate for IUI in women between the ages of 38 and 40 is 9%. In their early 40s, the success rates were only about 3-9%.

The location of fertilisation and the number of eggs the female produced are the common differences between IUI vs IVF. Let us understand each factor and learn the distinctions:
| Factor | IUI | IVF |
| Ovulation | Treatments are administered to stimulate the growth and ovulation of one or two mature eggs (some women may not ovulate otherwise). | Before the ovulation stage, eggs are extracted. The procedure is carried out 34 to 36 hours before ovulation and after the last dose of fertility medication.
A patient will be given medication before egg retrieval to help relax and block pain. |
| Sperm Quality | IUI can help if the patient suffers from male factor infertility, which includes abnormal sperm count, motility, or morphology, as well as blocked vas deferens.
Through this procedure, the sperm and egg are brought closer together, improving the natural conception process. The sperm is placed much closer to its target (the egg) during an IUI. |
ICSI involves choosing the strongest, single sperm with the best motility and injecting them directly into a fertile ovum with a microneedle for assisted fertilisation.
A patient only requires one healthy sperm to use ICSI. For individuals with severe male factor infertility, IVF is more successful than IUI because of ICSI, or intracytoplasmic sperm injection. |
| Time To Pregnancy | Success with an IUI typically occurs during the first three or four treatment cycles. | Due to its higher success rate per cycle, IVF has a significantly shorter time to pregnancy. |
| Cost | IUI is significantly more cost-effective per cycle. For some people (like those with blocked tubes), IUIs may not be a good option, with almost no chance of success.
Additionally, after three IUI cycles, there is a low likelihood that any additional cycle will succeed. |
As compared to IUI, IVF is more expensive. Insurance coverage for IVF varies by state.
It is recommended to contact a health insurance company beforehand. |
If you or your partner has mild male-factor or unexplained infertility for no known cause, your doctor will likely recommend IUI. It is frequently suggested as the first step because it is more affordable and less invasive than IVF.
Doctors probably advise switching to IVF if you undergo three or four unsuccessful rounds of IUI. In some situations, they may also suggest skipping IUI and going straight to IVF if you (or your partner) have a condition like:
