You did everything right. The injections, the scans, the early mornings at the clinic, then two weeks of waiting that felt like two months. And the test says negative. If that’s where you are today, please hear this first: it’s not your fault.
IVF is a very good treatment, but it isn’t a guarantee. Even the best clinics in the world have cycles that don’t end with a baby. What’s worth knowing is that many failed cycles do have an explanation, and a fair number of those explanations can be tested for and treated.
Below are the eight most common reasons IVF doesn’t work. We’ll also talk about why Dubai has become such a popular choice for fertility treatment.
How often does IVF actually work?
According to the UK regulator, the HFEA, about 32% of embryo transfers using a woman’s own eggs result in a birth when she’s under 35. By 40 to 42, the figure falls to roughly 11%, and past 44 it’s about 4%.
So your odds depend a lot on your own situation. Age, general health, and the quality of the clinic all play a role. Now, on to the reasons.
1. Age
Age is the most significant one, and this mainly revolves around the eggs. All the eggs that a woman will ever have are present when she is born. With each passing year, there are fewer eggs left, and the remaining ones have a higher chance of being defective.
Older eggs are more likely to have the incorrect number of chromosomes. Embryos with the incorrect number of chromosomes do not implant, or, if they do, lead to a miscarriage. The American Society for Reproductive Medicine (ASRM) cites this as the major reason why success rates decrease post-35.
For women over 35 who have tried for six months without any success, it would be best not to wait. Simple tests such as AMH and antral follicle count will provide an idea about how many eggs are left.
2. Embryos that stop growing
In some cases, the egg and sperm do come together, but the embryo stops developing a few days later. It is quite common even among young and healthy couples. Scientific evidence suggests that many human embryos have chromosomal abnormalities, which nature simply eliminates.
Some couples may opt for PGT-A, a test of the embryo’s chromosomes prior to its transfer into the uterus. This test does not suit everyone, and experts have different opinions regarding its benefits. Your doctor will be able to advise you on this issue.
3. Problems in the womb
The womb is where the baby grows, so if it isn’t in good shape, even a healthy embryo can struggle to settle in. Doctors commonly find fibroids (growths in the womb wall), polyps (small growths on the lining), scar tissue from past surgery or infection, a lining that’s too thin, or chronic endometritis, a low-level inflammation.
An ultrasound or a hysteroscopy, where a thin camera takes a quick look inside, picks up most of these. And many can be put right before your next attempt.
4. Endometriosis and adenomyosis
In endometriosis, tissue that resembles the lining of the womb grows in the wrong place. In adenomyosis, it grows inside the muscle of the womb. Both may affect the quality of the eggs and implantation, and scientific studies prove that women suffering from moderate or severe endometriosis tend to have a worse outcome in IVF than women who don’t have endometriosis.
However, there is always something that may help. It could be medication, surgery, or several months of preparation with frozen embryo transfer after that.
5. Sperm problems
It is easy to overlook the fact that IVF requires two individuals. According to the World Health Organization, males account for almost fifty percent of all cases of infertility. There are several sperm related problems such as a low sperm count, lack of motility, abnormal sperm shape, and damaged DNA.
These things could be overlooked when conducting a basic semen analysis, hence the need for a sperm DNA fragmentation test. Intracytoplasmic sperm injection is done to inject a single sperm into an egg. It helps to solve the problem for most individuals. Quitting smoking and reducing stress also works.

6. Lifestyle and health conditions
People do not realize the power of good habits. Many scientific facts prove the relationship between low rates of success in IVF and smoking, overdrinking, being overweight/underweight, excessive use of caffeine, lack of sleep, and high levels of stress. In addition, some diseases, such as thyroid disorders, diabetes, and PCOS, can be obstacles as well if not treated properly.
Fortunately, there are positive sides to it as well; even a few good months of nutrition, walking, and sleeping will help.
7. A treatment plan that doesn’t suit your body
No two women will react the same way to fertility medications. Some may ovulate too little, while others may ovulate too much, resulting in OHSS. An incorrect dosage of medications or incorrect administration of the trigger shot could mean that the number and quality of eggs are affected.
The timing of the transfer also plays an important role since the uterus will only accept an embryo at a particular time.
So make sure to ask for a plan made especially for you rather than something that was successful for your friend. In some cases, all the embryos may be frozen for transfer later.
8. Lab quality and clinic experience
This is often forgotten, but really important. In the embryology laboratory, air quality, temperature, machinery, and expertise of the embryologist all play a role in the development of the embryos. The expertise of the doctor is also relevant in selecting and transferring the embryos gently.
When choosing a clinic, always ask them about the success rate of different age groups. Ask how many cycles they conduct per year, and what technology they use. Good clinics like Dr. Mazen IVF will be more than willing to provide this information.
What if nobody can find a reason?
Sometimes every test comes back normal, and the cycle fails anyway. Doctors call this unexplained failure, and it’s more common than you’d expect. It doesn’t mean you’ve run out of options. Several couples succeed on a second or third cycle, and the studies show your cumulative chance of a baby grows over several attempts, especially under 40.
Why choose Dubai for IVF?
More and more couples from India, Africa, Europe, and the Middle East are asking this. Here’s an honest look at the reasons.
- Clear regulation. The UAE has a federal law on medically assisted reproduction, and clinics must be licensed by health authorities such as the Dubai Health Authority. That gives patients an extra layer of safety.
- Modern labs. Many clinics offer ICSI, PGT testing, and time-lapse embryo monitoring.
- Doctors from around the world. Fertility specialists and embryologists work in Dubai from many countries, so you can often find care in your own language.
- Simple travel. Flights from India, Asia, Africa, and Europe are short, visas are straightforward, and the city is safe and clean.
- Everything nearby. Tests, treatment, and recovery all happen in the same area, which takes some of the stress out of the process.
Is it the best country for IVF? There’s no one answer, because the best place is whichever fits your health, your budget, and your legal situation. Still, Dubai is on a lot of families’ shortlists. One thing to keep in mind: UAE law applies to all fertility treatment in Dubai, and care is generally offered to married couples. Confirm the rules with the clinic before booking travel.
If your cycle has failed
- Give yourself time. Sadness, anger, or feeling numb are all normal. Talk to your partner, a friend or a counselor.
- Go through the cycle with your doctor. How many eggs were collected? How many were fertilized? How did the embryos develop?
- Do the extra tests that make sense, such as a womb check, a sperm DNA test, or genetic testing of embryos.
- Fix what can be fixed, whether that’s a womb issue, a lifestyle habit, or the treatment plan itself.
- Try again when you’re ready. Nobody wins a prize for rushing into the next month.
One last thing
A failed cycle hurts, but it isn’t the end of your story. Age, embryo quality, womb health, sperm health, daily habits, the treatment plan, and the lab can each play a part. Once the cause is found, the next cycle can be planned far better.
If you’re considering fertility treatment in Dubai, or you’d like a second opinion after a failed cycle, Dr. Mazen and the team are happy to review your case and talk through your options. Book a consultation and get clear answers.
