IVF is recommended when other treatments haven't succeeded, when specific medical conditions make it the most effective option, or when age and circumstances suggest it offers the best chance of pregnancy. It's not always the first step, your specialist will recommend the most appropriate treatment based on your individual situation.
Common Questions About IVF Recommendations
When is IVF typically recommended?
IVF may be recommended in several situations:
- Tubal factor, blocked or damaged fallopian tubes preventing natural conception
- Severe male factor, very low sperm count or quality requiring ICSI
- Endometriosis, moderate to severe endometriosis affecting egg quality or tubal function
- Unexplained infertility, when simpler treatments like IUI haven't worked
- Ovarian reserve concerns, low egg numbers where maximising each cycle matters
- Genetic testing needed, preimplantation genetic testing (PGT) to screen embryos
- Previous treatment failure, when ovulation induction or IUI haven't been successful
How do doctors decide if I need IVF?
Your fertility specialist considers multiple factors when recommending treatment:
- Your age and how long you've been trying to conceive
- Results of fertility investigations (blood tests, ultrasound, semen analysis)
- Your specific diagnosis or diagnoses
- Whether simpler treatments have been tried and their outcomes
- Your ovarian reserve (AMH level and antral follicle count)
- Your personal preferences and circumstances
In some cases, IVF may be recommended as a first-line treatment, for example, with bilateral tubal blockage or severe male factor infertility where simpler treatments are unlikely to succeed.
Is IVF the only option for infertility?
Definitely not. Fertility treatment is a spectrum, and IVF sits towards the more intensive end. Other options include:
- Lifestyle optimisation, weight management, reducing alcohol, stopping smoking
- Ovulation induction, medication to stimulate egg release
- Intrauterine insemination (IUI), placing washed sperm directly into the uterus
- Surgery, for conditions like endometriosis, fibroids, or tubal issues
- Hormonal treatment, for specific hormonal imbalances

At what age should I consider IVF?
Age is an important factor in fertility treatment decisions. General guidelines suggest:
Under 35
Seek help after 12 months of trying. Simpler treatments may be tried first.
35-39
Seek help after 6 months. May move to IVF sooner if indicated.
40+
Seek specialist advice promptly. IVF is often recommended earlier due to declining success rates with time.
Known issues
If you have a known condition affecting fertility, don't wait, seek specialist advice regardless of age.

Can IVF help with male infertility?
Yes, IVF with ICSI has been one of the most significant advances in treating male factor infertility. ICSI involves injecting a single sperm directly into the egg, meaning that even very low sperm numbers can achieve fertilisation.
IVF with ICSI can help in cases of very low sperm count, poor sperm motility or morphology, high sperm DNA fragmentation, previous vasectomy (using surgically retrieved sperm), and obstructive azoospermia. Learn more about when to see a fertility specialist.
What if I've already tried IUI without success?
If 3-4 well-timed IUI cycles haven't resulted in pregnancy, IVF is usually the recommended next step. IVF offers significantly higher success rates per cycle and provides more information about egg quality, fertilisation, and embryo development. This additional insight can also help guide future treatment decisions.
