Iui Vs Ivf: What’s Right For Me?

Deciding on the best fertility treatment can be both confusing and overwhelming. Intrauterine insemination (IUI) and in vitro fertilisation (IVF) are two common treatments that couples consider. While both methods aim to assist with conception, they differ in technique, cost, and success rates.

This article provides an overview of IUI and IVF to help you determine which might be best suited for your personal circumstances.

IUI: A Brief Overview

1. What Is IUI?

IUI, or intrauterine insemination, is a procedure where sperm is directly introduced into the woman’s uterus. This process increases the number of sperm that reach the fallopian tubes, thus enhancing the chance of fertilisation.

2. Who Can Benefit From IUI?

IUI may be considered if:

  • There is unexplained infertility.
  • There’s a minor male factor infertility.
  • Couples are using donor sperm.
  • There are issues related to cervical factors.
  • Couples are in same-sex relationships.

3. The Procedure

The IUI procedure is relatively simple:

  • The woman might take fertility drugs to stimulate ovulation.
  • The man provides a sperm sample, which is then “washed” to separate the healthy sperm.
  • A thin tube (catheter) is used to insert the sperm directly into the uterus.

IVF: An In-Depth Look

1. What Is IVF?

IVF, or in vitro fertilisation, involves retrieving eggs from a woman’s ovaries and fertilising them outside her body. Once the eggs are fertilised, the resulting embryos are assessed for quality, and one or more are implanted into the woman’s uterus.

2. Who Can Benefit From IVF?

IVF might be a suitable option if:

  • There is severe male factor infertility.
  • The woman has blocked or damaged fallopian tubes.
  • There are issues with ovulation.
  • Previous IUI treatments have been unsuccessful.
  • Endometriosis or polycystic ovary syndrome (PCOS) is present.

3. The Procedure

The IVF process is more involved than IUI:

  • Fertility drugs are administered to stimulate the ovaries to produce multiple eggs.
  • Eggs are retrieved from the ovaries through a minor surgical procedure.
  • In a lab, the eggs are fertilised with the sperm.
  • Quality embryos are selected and transferred to the uterus.

Success Rates: IUI vs IVF

When discussing IUI and IVF, it’s vital to consider success rates. IUI success rates are generally lower than IVF. Typically, the IUI success rate ranges from 10-20% per cycle, depending on various factors like age, the reason for infertility, and the use of fertility drugs.

In contrast, the average IVF success rate is higher, often between 20-35% per cycle, though this too can vary based on similar factors.

Cost Implications

Another significant distinction between IUI and IVF is cost. IUI is generally more affordable than IVF. In the UK, the cost of an IUI cycle can range from £500 to £1,500, while IVF treatments can cost between £5,000 to £8,000 per cycle.

It’s crucial to note that these figures can vary based on the clinic, location, and any additional treatments or tests required.

Making the Right Choice for You

Your choice between IUI and IVF will ultimately depend on your personal situation. Here are some factors to consider:

  • Medical Conditions: If there are severe reproductive issues, IVF might be the recommended route.
  • Age: As age increases, especially after the age of 35, IVF tends to have better success rates than IUI.
  • Budget: If you’re on a limited budget, IUI may be a good starting point, but remember that if multiple IUI cycles are needed, costs can accumulate.
  • Timeline: IVF often results in a quicker path to pregnancy, especially if IUI has been tried and hasn’t succeeded.


Both IUI and IVF offer hope for couples facing infertility. The best way to decide which treatment is right for you is by consulting with a fertility specialist. They can provide personalised advice based on your health, medical history, and personal preferences.

Whatever you choose, remember that every journey to parenthood is unique, and there’s no one-size-fits-all solution.
