Understanding your fertility options is essential to making informed decisions that support your family-building goals. Intrauterine insemination (IUI) and in vitro fertilization (IVF) are two common fertility treatments that have helped many individuals and couples hoping to grow their families. While both treatments aim to achieve pregnancy, they differ in approach, cost, and success rates. Fertility specialist, Sally Vitez, M.D., helps explain the differences between IUI and IVF to help you navigate your fertility journey with confidence and compassion. 

What is IUI? 

Intrauterine insemination (IUI) is a relatively simple and less invasive fertility treatment. During an IUI, sperm is collected, washed, and then directly placed into the uterus around the time of ovulation. This procedure increases the chances of sperm reaching and fertilizing an egg, making it a good option for couples dealing with mild male infertility, unexplained infertility, or ovulation disorders. Patients can expect to take Clomid for 5 to 7 days typically starting on day 3 of their menstrual cycle. Additionally, the physician may prescribe an Ovidrel injection prior to the IUI to trigger the egg release.  

Why choose IUI? 
  • Less invasive: IUI is a less invasive procedure compared to IVF, involving a brief procedure typically done in a monitoring room and most often does not require any pain medication.  
  • Fewer medications: During an IUI cycle, medications to help stimulate ovulation or assist with uterine lining may be administered; however, this course of medication is often smaller compared to an IVF cycle.  
  • Lower cost: Due to the less invasive nature and fewer medications, IUI is more affordable than IVF.  
  • Quicker to start: IUI cycles can often be started more quickly, with less preparation time than IVF. 
Considerations: 
  • Lower success rates: An IUI cycle is generally attempting to achieve pregnancy rates similar to the standard chances of conception in each month if infertility weren’t a factor. This makes IUI ideal as a first-line treatment for many; however, may not be suited  for older women or those with more complex fertility issues. 
  • Multiple cycles: Similar to non-assisted conception where it can take several months to become pregnant, it may take several IUI cycles to achieve pregnancy, which can be emotionally and financially taxing. 

What is IVF? 

In vitro fertilization (IVF) is a more advanced fertility treatment where eggs are retrieved from the ovaries and fertilized with sperm in a laboratory. The resulting embryo(s) are then transferred to the uterus. IVF is often recommended for couples with more complex infertility issues, such as blocked fallopian tubes, severe male infertility, or genetic concerns. 

Why choose IVF? 
  • Higher success rates: IVF generally offers higher success rates compared to IUI, particularly for those with more complicated fertility challenges. 
  • More control: During an IVF cycle, one or two embryos may be transferred back to the patient. This allows the embryology and physician team to select the most viable embryos as well as the option for genetic testing to ensure the healthiest embryos are transferred. 
  • Flexibility: IVF can be tailored to individual needs, including options like using donor eggs or sperm, surrogacy, or using previously frozen eggs or embryos. 
  • Overcoming obstacles: For couples facing physical barriers like tubal issues or severe male infertility, IVF may be the most effective option. 
Considerations: 
  • More invasive: IVF involves daily injections, egg retrieval, and embryo transfer. 
  • Higher cost: Both the medications and procedure costs for an IVF are often more expensive than those required with an IUI.  
  • Emotional and physical demands: The process can be physically and emotionally demanding, requiring support from healthcare providers, partners, and loved ones. 

Which fertility treatment is right for you? 

Your fertility specialist at SGF will help you understand the best options based on your unique situation, but here are some general guidelines: 

  • IUI may be right if: You’re dealing with mild infertility issues, prefer a less invasive approach, and are comfortable with a potentially lower success rate. In some cases, your insurance coverage may also require IUI cycles prior to moving to other treatment.  
  • IVF may be right if: You’re facing more complex infertility challenges, have tried IUI without success, or seeking the higher success rates and flexibility that IVF offers.
