The world of fertility treatments can be a daunting landscape, filled with acronyms, procedures, and endless possibilities. Amidst this realm, two techniques stand out: intrauterine insemination (IUI) and in vitro fertilization (IVF). These treatments offer couples struggling with infertility a glimmer of hope, but understanding their nuances is crucial for making informed decisions.

Intrauterine insemination (IUI) and in vitro fertilization (IVF) are two types of fertility treatments that help couples who are having trouble conceiving. Both treatments involve the use of assisted reproductive technologies (ART) to increase the chances of pregnancy. However, there are some key differences between the two procedures.

Where fertilization occurs 

  • IUI: Fertilization occurs internally, when the sperm is injected directly into the woman's uterus.
  • IVF: Fertilization occurs externally, in a laboratory. The egg is retrieved from the woman's ovary and fertilized with sperm in a dish.

Invasiveness

  • IUI: IUI is a less invasive procedure than IVF. It is done in an outpatient setting and does not require anesthesia.
  • IVF: IVF is a more invasive procedure that requires surgery to retrieve eggs from the ovaries. It is typically done in an operating room under anesthesia.

Success rates

  • IUI: The success rate of IUI is generally lower than that of IVF. The average success rate for women under 35 who have used IUI is about 10-15% per cycle.
  • IVF: The success rate of IVF is generally higher than that of IUI. The average success rate for women under 35 who have used IVF is about 60-65% per cycle.

When to use IUI or IVF 

In general, IUI is a good option for couples who have mild infertility issues, such as:

  • Unexplained infertility 
  • Mild male factor infertility 
  • Elevated cervical mucus that may interfere with sperm motility IVF is a better option for couples 

who have more severe infertility issues, such as:

  • Blocked fallopian tubes
  •  Low ovarian reserve 
  • A history of recurrent miscarriages
