When having IVF, most patients will grow a few follicles and the doctor will successfully retrieve eggs from most of these follicles. However, sometimes no eggs are retrieved at the egg collection. There are essentially five possible reasons as to why this may happen.
Five Common Reasons Why Eggs Were Not Collected
1. The follicle may have ruptured (ovulated) prior to the egg collection. This may happen if the trigger injection is mistimed (i.e. given earlier than instructed) ; or if the egg collection is delayed beyond 37 hours of trigger injection administration. If the trigger timing is not correct or the egg collection procedure takes place 37 hours or more after the trigger injection is administered, there is a high chance that the follicles present on the ovaries can rupture. This can result in the eggs being lost in the follicular fluid that is released from the ovary at the time of ovulation.
2. The doctor may experience technical problems during the egg collection procedure . This may happen when the patient is very obese; or if there are adhesions (scar tissue) in the pelvic region. Both obesity and scar tissue make it more difficult for the vaginal ultrasound probe to access your ovaries. This can be a major problem if difficulties arise and the egg collection is not done under general anesthesia. In these situations, it may be technically impossible for the doctor to access the ovaries to drain the follicles in search of eggs.
3. Generally speaking the number of eggs expected from follicles seen on ultrasound scan is approximately 80-90%. It is important to remember that there will never be more than one egg per follicle. Unfortunately, when there are lower numbers of follicles, there is a higher chance that the egg is not collected in the follicle fluid.
4. Another reason for the failure to retrieve eggs from mature follicles is due to empty follicle syndrome.
5. Finally, another possible reason for no eggs being collected during the egg collection procedure is a patient may have low ovarian response. This is more commonly seen in older women having IVF. Apart from performing an anti mullerian hormone test (AMH), there is no other way of predicting this in advance.
Why were there no eggs in my follicles? ›
This is because some follicles are small and don't contain eggs; while others are large, and have formed cysts which do not have an egg. It's not possible to differentiate between a cyst and a large follicle based on the ultrasound scan images.Why are there so few eggs retrieved? ›

No Eggs Retrieved
Theoretically, you could have a good number of follicles but retrieve no eggs from them. If there are no eggs, fertilization can't happen and the cycle would end.
Empty Follicle Syndrome (EFS) occurs when no eggs are retrieved after follicular puncture. This alteration occurs in a small percentage of women who are stimulated for an assisted reproduction treatment and no eggs are found when the follicles are aspirated.Can empty follicle syndrome be treated? ›
To date, empty follicle syndrome (EFS) has only been reported in GnRH agonist down-regulated IVF cycles. Some cases have been successfully treated by changing the batch, or by repeating the dose of hCG.How can I increase my follicle count? ›
Taking vitamin A boosts oocyte quality and embryo development, while vitamin E lowers oxidative stress and boosts follicular blood supply (necessary for high-quality eggs). Also, B vitamins help with DNA synthesis as well.Why did so few eggs fertilize IVF? ›
There can be many reasons why eggs don't fertilize during the IVF process. It can be down to poor sperm quality (that is the sperm could not reach the egg or bind to the egg), it could be down to the egg quality itself, not being able to receive the components of the sperm in order for it to fertilize.What is a good number of eggs for retrieval? ›
As a rule of thumb, however, having about ten to 12 mature eggs after egg retrieval (not all eggs retrieved will be developed or mature enough to fertilize) is a good number of eggs and will give a woman a good chance of having at least one normal embryo, which gives a woman a 65 percent chance of pregnancy.What causes eggs not to fertilize IVF? ›
The sperm head may not have decondensed, which would cause failed fertilization due to the DNA of the sperm remaining 'locked' in the sperm head. This would cause failed fertilization or abnormal fertilization. The egg may not have been activated and didn't participate in the intracellular steps of fertilization.How long can eggs go uncollected? ›
In fact, eggs can actually be left in the coop for 4-5 weeks and still be fresh to eat. This is because unwashed eggs have a protective bloom, or cuticle, which naturally prevents bacteria from the outside of the egg from entering inside. When you wash eggs, this bloom is then also washed away.
Why am I not responding to IVF drugs? ›
If a woman has diminished ovarian reserve (identified by high blood levels of follicle stimulation hormone (FSH), low blood levels of anti Müllerian hormone (AMH) or a low antral follicle count on ultrasound), she may not have as robust (or any) response to stimulation.What estrogen level is needed for egg retrieval? ›
During IVF treatment, a typical estrogen level will be less than 75 at the time of baseline evaluation and may get as high as 2,000 – 4,000 (in a normal menstrual cycle the estrogen level starts out less than 50 and peaks at about 250 – 350).What happens if you have no eggs in your ovaries? ›
Complications of primary ovarian insufficiency include: Infertility. Inability to get pregnant can be a complication of primary ovarian insufficiency. In rare cases, pregnancy is possible until the eggs are depleted.Why do I have no follicles? ›
In most cases, the cause of the follicle problem is unknown. But sometimes the cause may be: Genetic disorders such as Fragile X syndrome and Turner syndrome. A low number of follicles.Can a woman not produce eggs? ›
Primary ovarian insufficiency.
Also called premature ovarian failure, this is usually caused by an autoimmune response or by premature loss of eggs from your ovary, possibly as a result of genetics or chemotherapy. The ovary no longer produces eggs, and it lowers estrogen production in women under age 40.
In order to make diagnosis of empty follicle syndrome we use a rapid home pregnancy test kit in order to check the urine (obtained by catherisation) for the presence of hCG. (Instead of urine, it's also possible to do the test on the aspirated follicular fluid.)Can you ovulate without a follicle? ›
During ovulation, prostaglandins are also involved in the inflammatory response needed for your follicle to release an egg. If the follicle does not release the egg, then ovulation cannot occur (2).How do you activate dormant follicles? ›
One very good medication to reactivate dormant hair follicles is minoxidil. Applied regularly to the scalp, minoxidil can re-grow hair that has completely stopped growing. The only caveat is that once you start taking it, you'll have to keep taking it indefinitely.Can you increase your egg count? ›
Women are born with ~1 million potential eggs (in the form of ovarian follicles), but that's all the eggs we'll ever have. Unlike skin cells or blood cells, which regenerate, our bodies aren't able to make more egg cells.What triggers follicle growth? ›
Follicle stimulating hormone is one of the hormones essential to pubertal development and the function of women's ovaries and men's testes. In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation.
What vitamins help follicle growth? ›
Vitamin B6 and B12: B vitamins not only help to promote egg health and prevent ovulatory infertility, but they may even improve sperm quality. For women, high homocysteine levels in the follicles are often associated with problems with ovulation.Why do females produce so few eggs? ›
Within a woman's lifespan, large numbers of follicles and oocytes will be recruited to begin the growth and maturation process. The large majority, however, will not reach full maturity. Most will die off in a process called atresia. Thus, only about 300-500 of these eggs will mature over a women's life span.Do poor quality eggs fertilize in IVF? ›
Immature Egg Pictures: Advanced Fertility Center of Chicago
Meiotic competence is achieved when eggs undergo the first meiotic reduction to the metaphase II stage (“M2”) of meiosis. Do immature eggs fertilize with IVF? No. Immature eggs are not capable of fertilizing.
For women with 1–4 eggs at retrieval it was 30.8% and for 5–9 eggs it was 36.2%. In women age 35–39 (n=543), optimal pregnancy rates (34.8%) were achieved with 5–9 eggs at retrieval. Less than 5 eggs significantly reduced the pregnancy rate (15.6%) whereas more than 10 eggs yielded pregnancy rates between 28 and 29%.What are the symptoms of poor egg quality? ›
- Absent or late periods.
- Shorter-than-average menstrual cycles.
- Irregular periods with a heavy or light flow.
- History of miscarriage.
That said, Dr. Zore puts the percentage of mature retrieved eggs that get fertilized, make it to the day 3 embryo stage, and ultimately to the day 5 or 6 blastocyst stage at around 30%-50%, depending on age and other infertility factors.Is 3 eggs enough for IVF? ›
Women under 38 in our IVF program have acceptable live birth rates even with only 3 – 6 eggs, do better with more than 6 eggs, and do best with more than 10 eggs.

The Bologna criteria of “poor response” to COH for IVF, necessitates the presence of two, or more, of the following three criteria: (1) advanced maternal age or other risk factor(s) for POR; (2) a previous POR on COH for ART/IVF; and (3) an abnormal ovarian reserve test (80).What to do if IVF keeps failing? ›
Summary for a second try with IVF:
If there were difficulties with the ovarian stimulation or low numbers of eggs – consider modifications to the drug protocol. If there were average or good looking embryos for transfer, but none implanted, try IVF a second time at the same or a different IVF clinic.
Your Next Steps
Your doctor will advise you after each failure and recommend testing before you move forward. At that point you do have options, depending on the results of those tests. Doctors advise preimplantation genetic testing for those who have multiple IVF failures.
During the IVF cycle, drugs are given to encourage the development of follicles in the ovary. The drugs do however stimulate the ovaries to produce more follicles than would normally grow in a menstrual cycle. The number of follicles that develop depends on many factors, including your age and the hormone test results.Is 4 follicles enough for IVF? ›
Most fertility clinics like to see 4 mature follicles before triggering ovulation for IVF. Again, this is not an exact science; fewer follicles producing high quality eggs may be enough. Too many could indicate Ovarian Hyperstimulation Syndrome (OHSS).How thick should endometrium be for egg retrieval? ›
However, it is generally accepted that an endometrial thickness below a minimum value of 6 to 8 mm showed negative predictive value for IVF outcomes,[1,2,24–26] and clinical pregnancy as well as live birth rates are significantly higher in patients with an endometrial thickness >9 to 10 mm.
One of the most common treatments for diminished ovarian reserve is supplements like dehydroepiandrosterone (DHEA), a mild androgen. DHEA is produced naturally in the body, but levels of DHEA decrease with age. DHEA supplements can increase fertility.Why didn't all my follicles have eggs? ›
This is because some follicles are small and don't contain eggs; while others are large, and have formed cysts which do not have an egg. It's not possible to differentiate between a cyst and a large follicle based on the ultrasound scan images.Can stress cause low follicles? ›
