Is IUI or IVF more successful?

A common consideration to keep in mind for the IUI versus IVF decision is that success depends largely on variables such as female age, the reason for infertility, and the fertility drugs used. With IUI, women under 35 often have a 10 to 15 percent chance of getting pregnant with just one cycle.

With an IVF cycle using a woman’s own eggs, the average national success rates range from 45 percent to 50 percent or more for patients under 35 years old. These success rates can be pushed even higher, typically in the 60 to 70 percent range, when the embryos are genetically tested and selected before transfer.

Age plays a huge role in the success of IUI and IVF. Success rates for both procedures drop precipitously for women over 40 using their own eggs.

Is ICSI more effective than IVF?
Is ICSI more successful than IVF?

Two of the most common fertility treatments are In Vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI). The key difference between IVF and ICSI is how the sperm fertilizes the egg. In IVF, the egg and sperm (of which there are multiple) are left in a petri dish to fertilize on their own. In ICSI, one sperm is directly injected into the egg.

The ICSI procedure fertilizes 50 to 80 percent of eggs. You might assume all eggs get fertilized with ICSI-IVF, but they don’t. Fertilization isn’t guaranteed even when a sperm is injected into the egg.

This study investigated in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in to treat infertility in women over the age of 40.

This study found that IVF resulted in higher rates of implantation and adjusted live-birth compared to ICSI.
