Before the fertilization can take place, the woman takes fertility medication to stimulate the ovaries to assist in successful egg retrieval. The egg retrieval is performed under sedation and insemination is performed the same day. After the fertilization, the embryo is monitored carefully to determine when transfer to the uterus should be made.
So, if fertilization is successful, the embryo implants there as well. With IVF, fertilization takes place externally, or outside of the uterus, in a lab. Ideally, the fertilized egg would then implant in the lining of the uterus, resulting in pregnancy and delivery of a full-term baby or babies.
Artificial insemination is considerably less expensive than IVF and less invasive. IVF and IUI have a few factors in common, and they mostly have to do with preparing for treatment and the basic processes of human conception. Before insemination or fertilization, both IUI and IVF may include a regimen of fertility drugs to increase success rates in fertilization or in the case of IVF, to assist in ovulation and aid in egg retrieval. One of the first things people should do when exploring fertility treatment options is to compare intrauterine inseminations IUI and in vitro fertilization IVF as they are two of the most common and effective fertility treatments.
We start things off with a high-level overview, then jump into the different types of each treatment, discuss treatment details, key decisions within each treatment, success rates, cost comparisons, risks, and who each treatment might be a good fit for.
There are a few different types of insemination based on where the semen is deposited and four different types of IUI cycles based on the medications used in the treatment. Your preferences, fertility diagnostic testing , and history help guide which type of IUI cycle is best for you.
There are two main types of artificial inseminations :. No matter what type of IUI cycle you choose, your cycle is monitored either with consistent blood work and ultrasounds or at home via an ovulation predictor kit.
If your IUI cycle includes medications, you will likely be monitored with bloodwork and ultrasounds to ensure follicular development and a safe and effective cycle.
The best way to view the different types of IVF is to understand that IVF is an umbrella term used to describe a procedure where fertilization happens outside of the body. Various types can also be combined. An IUI procedure is the process of directly injecting sperm into the top of the uterus. This increases the odds of conception by reducing the distance the sperm must travel to meet the egg. An IUI treatment can be summarized into a few steps:.
About a quarter to a third of patients on injectable FSH will experience side effects, including headaches, mood swings, insomnia, hot or cold flashes, breast tenderness, bloating, or mild fluid retention.
Additionally, the injection site could become sore, red, or slightly bruised. Again, these side effects should resolve without additional care after the cycle is over. OHSS is associated with swollen, enlarged ovaries and the collection of fluid in the abdominal cavity.
While many people think of multiples—such as twins, triplets, and more—being the result of IVF, when a single embryo is transferred the gold standard for IVF , the chance of multiples is quite low.
The highest chance of multiples actually comes from a medicated IUI cycle specifically an IUI cycle with injectables , because doctors have less control over how many eggs are released and fertilized.
For example, a couple in their early 30s with unexplained infertility and no obvious impediments to pregnancy are likely to start with IUI. A woman with blocked, tied, or absent fallopian tubes should start with IVF, which bypasses the tubes. The best way to understand which is the better treatment for you—IUI vs.
IVF—is to have a consultation with a reproductive endocrinologist. Contact us to schedule a consultation. Great question! Again, this is going to depend on a few factors: your personal diagnosis, age, budget, insurance coverage, and family goals. Historically, many patients did 3—6 IUI cycles before moving on to IVF and this was often what their insurance coverage required , and some younger patients still adhere to this standard.
