Intrauterine insemination (IUI) treatment involves injecting sperm from a partner or donor directly into the womb around ovulation. The success rate of IUI can vary depending on several factors, including age and medical history.
At TFP Fertility, we provide IUI treatment across all our clinics. We understand that many people want to know about IUI success rates, especially how they differ by age and individual circumstances, and we’re here to support you every step of the way.
At TFP Fertility, success rates for intrauterine insemination (IUI) vary, with individuals aged 35 and under experiencing an average success rate of around 15% per cycle.
It’s important to remember that IUI success rates can be affected by factors such as age and specific fertility challenges. We’ll discuss these in detail during your consultation to give you a clear understanding of what to expect.
As women age, the number of available eggs naturally decreases, which can reduce the chances of pregnancy. Because of this, IUI may be less effective for individuals in their late 30s or over 40. For those in this age group, other fertility options like IVF treatment may offer a higher chance of success.
It’s also important to note that if you, your partner, or donor have fertility issues such as blocked fallopian tubes, a low egg count, or male factor infertility, then IUI treatment is unlikely to be effective. In such cases, alternative fertility treatments may be recommended.
Like any fertility treatment, IUI success depends on several factors. Here are some tips to help improve your chances of a successful outcome:
Maintain a healthy lifestyle – Eating plenty of fruit and vegetables, exercising regularly, and getting enough sleep support your overall health and fertility. Being overweight can affect ovulation and sperm production, so it’s important to keep this in check.
Avoid smoking and alcohol – Smoking and heavy alcohol intake can reduce sperm quality and interfere with embryo implantation in women, making it harder to conceive.
Relax and manage stress – Stress can negatively impact your chances of conception and how your body responds to treatment. Activities like meditation, reading, or walking can help you relax.
Keep regular appointments with your GP – Regular health check-ups ensure you are fit and ready for IUI treatment, giving you the best possible chance of success.
Many individuals undergo multiple cycles of IUI treatment before achieving a successful pregnancy, so success rates can vary. Therefore, it's important to consider the costs involved.
Furthermore, The Human Fertilisation and Embryology Authority (HFEA) recommends that if you haven't had success after six cycles of IUI, you should contact your GP or fertility clinic. They can conduct tests to explore other options, such as IVF, which may be more suitable for you.
