Do IVF Babies have higher risk of abnormalities?

 

Question: We are thinking of going through an IVF, but we are concerned whether IVF babies have higher risk of abnormalities. We are also concerned that IVF babies are less healthy than their counter-parts and have shorter life-span, is it true?

 

Dr Helena’s answer:

Since the advent of IVF and Assisted Reproductive Technology, there had been constant debates on its safety and implication towards the health of the next generation. One of the biggest concerns is whether these fertility treatment will give rise to increase risk of congenital abnormalities in babies born as a result of IVF.

These debates and concerns are certainly valid. After all, the process of IVF in creating life outside human body in a Petri dish and then putting them back into the human body to let it grow into a baby is certainly mind blowing. How would we ensure that the doctors and scientists know what they are doing? And mind you, the IVF process were the results of many trials and errors. What makes you think the product (which is the baby), is not plagued with defects and errors?

Intensive research in the early years, and a thriving population that has now grown to more than 5 million IVF children worldwide, have reassured scientists, but they have not stopped studying and trying to improve the process.

Recent discoveries in epigenetics – the study of how environmental factors can affect gene activity, and how a person’s risk of getting chronic diseases is “programmed” into them before they are even born – have opened up new possibilities.

Much of today’s research stems from the Barker hypothesis, which proposes that birth weight may be linked to the likelihood of getting certain diseases. IVF babies are known to have lower average birth weights – even if the difference, at about 20-30 grams, is small. Scientists are now investigating whether IVF conception equates with more hospital admissions, and an increased risk of cardiovascular disease, high blood pressure and diabetes in later life. However, there is no good evidence as yet to suggest likewise

A recent study by the Human Fertilization and Embryology Authority, which linked 106, 381 HFEA register records from 1992-2008 to the UK’s National Registry of Childhood Tumours (NRCT) is one of the largest population-based linkage studies ever carried out. This study has found no association between ART and childhood cancer. This finding offers comfort to those patients facing the difficult decision about whether to undergo fertility treatment or not.

In 2012, scientists at the University of California, Los Angeles (UCLA) looked at birth defects among infants born both via IVF and conceived through natural means in California, which has the country’s highest rate of IVF use. They included babies born after IVF and other assisted reproductive treatments such as couples’ use of fertility-enhancing drugs and artificial insemination.

Among 4795 babies born after IVF and 46,025 infants who were conceived naturally, 3,463 babies had congenital birth defects. Even after controlling for factors that can affect such birth defects, such as mother’s age, and race, which can influence rates of genetic and environmentally driven developmental disorders, 9% of infants born after IVF had birth defects compared to 6.6% of babies who were conceived naturally. Overall, the babies born after IVF were 1.25 times more likely to be born with abnormalities. The researchers did not find a link between birth defects and other fertility treatments like artificial insemination or ovulation induction.

It’s possible that the higher rate of abnormalities with IVF is due in part to whatever was contributing to infertility in the first place, say the researchers. But some of the researchers’ view was the fact that an increase was not seen among babies conceived using artificial insemination or ovulation induction suggests that process of IVF itself, in which eggs are removed from a woman, fertilized in a dish with sperm and then allowed to develop into embryos, which are transplanted back into the womb, is the primary culprit.

However, another more recent study in 2016 by researchers from the University of Adelaide and the University of Melbourne. The study reviewed all assisted reproduction technologies carried out in South Australia over a 16-year period from 1986 to 2002.

This was linked to data on birth outcomes from the South Australian Birth Defects Register (SABDR). The register includes a record of all live births, stillbirths, terminations, birth weight and congenital defects. Birth defects were also followed up for five years. The researchers looked at the statistical link between maternal factors and birth defects, and compared this between babies either conceived naturally or by IVF and ICSI. The study found no statistically significant increase in birth defect. There was some suggestion by the press that this study suggest that IVF reduces the incidence of birth defect in women after the age of 40, but was refuted by the research group due to its misleading nature.

With the advent of Pre-implantation genetic screening (PGS) & Pre-implantation genetic diagnosis (PGD), which is fast gaining popularity, scientist can now screen embryos to exclude chromosomal and genetic abnormalities. The use of these technologies may further decrease the incidence of birth defect and congenital abnormalities associated with chromosomal defects or genetic issues. However, more long term data is required to support this hypotheses.

 

In conclusion, although there had been great hypothetical concerns about the risk of cancers & birth defects amongst babies born following Assisted Reproductive Technologies (ART), the actual link is difficult to establish due to many confounding factors such as parental age, the cause of infertility and etc. the actual incidence of childhood cancers and birth defects are small and should not be a great stumbling stone to those who are considering going through fertility treatment to have their babies

What is the cause of my Failed IVFs?

020170209120847

 

Question: My husband and I had gone through 3 IVFs without success, does it mean that our chance of pregnancy is very slim? Is it due to my body condition?

 

Dr Helena’s Answer: To achieve a successful pregnancy through IVF, there are some basic pre-requisite factors:

 

(1) The age of the couple, especially the female partner
(2) The duration of Subfertility
(3) good quality and quantity of eggs and sperms to make good quality embryos
(4) a conducive uterus environment for implantation

Studies had also shown that there is a increasing cumulative pregnancy rate for women who went through a few cycles of IVF.

However, after going through three IVF without success, one may wonder whether there is light at the end of the tunnel.

Being a fertility doctor, I can understand how frustrating it would be. However, these IVF cycles which did not work out, may contain valuable information about your fertility. As we know, apart from being a treatment in its own right, IVF also serve as a diagnostic tool in its own right, by telling us how you respond to the medications, how your eggs and sperms qualities are, and how your embryos qualities are.

There a a few aspects we may consider to improve on for your next IVF treatment:

The IVF treatment protocol
The clinic
The sperm
The eggs
The uterus

Here are some consideration for you:

(1) The IVF Treatment protocol.

images (1)

While the IVF treatment protocol is pretty standard, every patient responds differently to the types and dosage of IVF medication. Each cycle teaches us how your body responds to the injections to help your follicles grow. It takes a good IVF doctor to be able to decide on the right dose and right type of medications, to get you to produce an optimal number of high quality eggs. Some young patients with normal ovarian reserve grow well in response to a standard protocol, patients with poor ovarian reserve and those with PCOS need a lot of extra attention and closer monitoring.

 

However, at the end of the day, some of this is trial and error. A good previous record can help us to learn from each cycle , until we can customize the perfect protocol for you
(2) The IVF clinic/centre.

 

It is important to note most IVF clinic/ centre are pretty standard, there are variations in terms of their operations and quality controls, and hence their success rates. In Malaysia, there is still no regulatory body that mandates each IVF clinic/ centre to report their success rates. However, it is important to look for credible centres with proper accreditation to ensure the quality of your IVF treatment.

 
(3) The sperm.

Poor sperm quantity & quality may be associated with failed fertilization of an egg during an IVF but with the advent of ICSI, these problems are easily over-come. However, if the sperms are have high DNA fragmentation, the resulting embryos may still have poor quality. Simple lifestyle changes such as stop smoking & alcohol, weight loose, exercise and consumption of good quality food which are rich in anti-oxidants are some of the key elements in improving sperm quality and IVF outcome

(4) The eggs.

human-egg-cell-womb

 

Human egg is a thousand times bigger than the sperm, and that the energy for cell division during embryo cleavage comes from the mitochondria in the egg’s cytoplasm, therefore, egg quality is another important factor for IVF success. Poor egg quality leads to poor embryos and hence failed IVF. The problem is that it’s very hard to make this diagnosis, as there is no blood tests or medical technology to identify poor eggs prior to an IVF cycle. In fact, IVF is a diagnostic tool in it own right, as egg quality can be assess during an IVF. To improve egg quality involves making lifestyle changes, improving diets, and sometimes some alternative medications such as DHEA.
(5) The uterus.

images (4)

It is probably a very Oriental or ‘Chinese’ believe that failure to get pregnant/ implantation is always the fault of the uterus. It is not unusually to hear the terminology of ‘cold uterus’ being cited for the reason for not getting pregnant. Hence, the idea of surrogacy has become very popular recently because of the disproportionate amount of media attention it attracts, and especially so when cross borders IVF had become extremely popular with the ease of medical access overseas. This had lead to the idea that the best medical solution for them after many failed IVF cycles is surrogacy. After all, the fact that the embryos are not implanting means the uterus must be ” defective” , so doesn’t it make sense to use a fertile woman’s uterus as an incubator for 9 months ? However, the truth is that surrogacy is an expensive and complex treatment option, which is best reserved for women without a uterus. It is also important to stress that Surrogacy is ILLEGAL in Malaysia. Research shows that the reason for failed implantation is much more likely to be genetically abnormal embryos ( because of poor quality sperms or eggs), rather than a uterine problem. However, in about 20-30% of women, failure in implantation maybe due to some small correctable issues in the uterus such as polyps or fibroids. These issues can be dealt with easily without having to resort to surrogacy

Can I get Pregnant with IVF if I have poor eggs and husband has poor sperms?

baby_0
Question: My husband and I had a fertility check and the doctor told us that we have poor sperms and poor eggs, may I know whether there is a chance of us getting pregnant with IVF?
Dr Helena’s answer:To achieve a successful pregnancy, may it be naturally or through assisted reproduction techniques, requires some basic pre-requisite factors:

(1) good quality and quantity of eggs and sperms to make good quality embryos
(2) a conducive uterus environment for implantation

In some cases whereby the husband’s sperms were poor in quantity & quality, whereby natural conception is virtually impossible, a Intracytoplasmic sperm injection (ICSI) technique to fertilize eggs during an IVF cycle overcomes certain degree of difficulty to create an embryo. However, if the sperms are extremely poor in quality, there are good scientific evidence to suggest that Fertilization and cleavage rates, quality of embryos as well as blastocyst development rates were significantly reduced, as semen quality decreased.

 

images (1)

An IVF cycle can also be unsuccessful if egg quality is poor even with good numbers of eggs (and embryos). Egg quality reflects about 95% of the final quality of an embryo. Poor egg quality, therefore, always leads to poor embryo quality. The quality of sperm, while not unimportant, is nowhere near as important as egg quality.

 

Embryos from low-quality eggs often fail to develop properly. In an IVF cycle, embryos are observed for 3 to 5 days as they grow, before they are transferred into the uterus. On the third day, good-quality embryos should reach 6- to 8-cell stage, and have a more or less regular shape. Embryos that don’t reach this stage within the first few days of development cannot be used for embryo transfer. In addition, some embryos that do reach this stage may be aneuploid (have chromosomal abnormalities). Aneuploid embryos, if they implant at all, are usually miscarried early in the pregnancy, thus also resulting in “failed” IVF.

 

Therefore, as many of our patients already know, it is not just the number of eggs that is important. The quality of eggs is also crucial for the success of IVF.

images (2)

Although some people are born to have poor sperms or eggs, majority of poor sperms and eggs can be improved by various means. Change of lifestyles such as stop smoking, stop alcohol intake, exercise moderately, weight reductions, good quality sleep, good nutrition by taking balanced diet, taking food rich in anti-oxidants, acupuncture and etc are some of the strategies one can employ to improve sperms and eggs quality.

 

Numerous studies had shown that with these improvements in lifestyle, the success rates of IVF in these group of patients improve remarkably.

 

Therefore, if your doctor had commented that your sperms and eggs are not good in quality, it maybe a good idea to look into your lifestyle and food intake to improve your chances of pregnancy

 

Does IVF has 100% of pregnancy rate ?

images
Question: My husband & I had tried conceiving through IVF but did not succeed. If we try IVF again, would my chances of getting pregnant lower than others? How do I increase my chance of success?
Dr Helena’s answer: The advent of IVF had greatly revolutionize the world of reproductive medicine. Millions of babies had been born, as the result of IVF. Without IVF, the birth of these babies would not had been possible due to various infertility issues
 
However, is IVF a magic bullet with 100% of pregnancy success rates? 
 
The answer is no, as we know, IVF’s success rate is not 100%.  
 
A few important factors associated with success rates of IVF is women’s age, the duration of Subfertility and whether there is any previous history of pregnancies. Some other factors includes the quality and quantity of eggs, sperm quality & lifestyle and habits 
 
For couples who didn’t succeed in getting pregnant during their first round of IVF, it is logically to wonder, whether they will ever get pregnant in their subsequent cycles of IVF
Generally the overall success rates of ONE IVF for a woman who is under the age of 35 is around 60-70%. We also know for a fact that a frozen embryo transfer has a higher pregnancy rate compares to a fresh embryo transfer.  For most women under 35, there is a good chance that she produces more than 2 good quality embryos each IVF cycle. most of the time, these excessive embryos can be frozen and can be used in the future. Technically speaking, ONE IVF cycle can potentially resulting more than one pregnancy, if the woman has lots of embryos and keep coming back to get them transfer into her uterus.
 
Coming back to the question, we know for sure that if you have a good number of embryos from the result of ONE IVF, the chance of you getting pregnant with the subsequent Frozen embryo transfer is extremely likely, especially if you are under the age of 35

However, if you have no embryos frozen, what is your option?

This chart below showed a cumulative live IVF births from a study conducted.

 

Cumulative Birth Rates

This study looked at all the women under the age of 42, who are going through IVF.

The study revealed that the pregnancy rate is around 40% in this group of women after they completed their first cycle of IVF. For those women who did not get pregnant the first round and went on having the second round of IVF, there were another 20% who got pregnant after the second round. Therefore, by the 4th IVF cycle, around 80% of women would have achieved a live birth.

 

This statistic clearly shows that if you  persevere and keep moving on, chances of you getting pregnant by the end of the 4th IVF is around 80%.

Baby

Therefore, it is not unusual for Fertility doctors to encourage our patients to keep moving on because the statistics had clearly show us the evidence.

To improve your chance of pregnancy for the next IVF, it is important to improve the quality of your eggs and sperms by eating healthy and  improve lifestyle, quit habits which can potentially jeopardize your success rates such as smoking, alcohol and stress. Speak to your fertility doctor about what are the other options in your IVF treatment.

Is IVF Painful?

 

Blog-1

 

Question: I am a person who is fearful of pain. I gathered that going through IVF will required multiple injections, surgery and other procedures which are painful. Is it true?

Dr Helena’s answer:

IVF sounds daunting to many people. A lot of us have perceptions that it is extremely expensive. Some of us thinks that it would bring us a lot of inconvenience, such as having to go to hospital everyday, lay in bed for a few months, quit our job and etc

One of the greatest fear many had was the perception of pain associated with IVF procedures. The thought of having daily injections made most of us wanting to run away and hide from the doctors. Some people are scared thinking about the egg retrieval procedures. Some are dreading the embryo transfer procedure, thinking that it would bring great pain and discomfort. Some dread the injections which are taken after the procedure, which are the progestogen injections, aimed to support the lining of the uterus whilst the embryos are implanting.

However, with the new development and breakthroughs in the world of reproductive medicine, IVF procedures had become more and more comfortable and easy to management, with minimal disruption to daily life.

First and foremost, the durations of injections had been shortened significantly with the use of antagonist injections in IVF. This method of doing IVF is called the antagonist cycle or the short protocol. So, instead of having 3 weeks of injections in the agonist cycle or long protocol, the advent of antagonist injections had lead to a shortened period of 10-12 days of injections. This had greatly reduce the discomfort one needs to go through with injections.
Ovulation-Induction_ShortProtocol
The use of self-administered FSH injection pens with extremely fine needles, had significantly cut down the pain one experienced during injections. This self- administered injections pens are given to patients to take home, and the injections are administered by patients themselves, so patients do not need to come to the clinic or hospital to have their daily injections. The needles used are similar to the ones used in the insulin injection pens, which is extremely fine and almost painless.

There is also another long acting FSH injection which given at the beginning of an IVF cycle and can last for 7 days. After the initial injection, the patient need not take FSH injection for the next 7 days, which significantly cuts down the number of injections required.

The egg retrieval procedure which usually happened after 10-12 days of injections involved having a light sedation in an operating theatre. In the past, the use of certain sedations such as Valium, Dormicum or pethidine administered by the IVF doctors whilst performing the egg retrieval procedure had appeared to be increasingly unsafe. In many IVF units, a proper IVF operating theatre with a trained Anaesthetist giving sedation during the egg retrieval procedure is becoming a norm and deemed acceptable in terms of safety. One of the advantage of the involvement of an Anaesthetist is that egg retrieval procedure is becoming almost painless, and hence optimizing patient experience in IVF.

Embryo transfer procedure is usually carried out 3-5 days after the egg retrieval. During the procedure, the embryos which were created following fertilization of the retrieved eggs with sperms are replaced into the uterus. This procedure is performed without anaesthesia or sedation, is relatively pain free. The experience is almost the same as having a cervical smear. Therefore, women should not feel fearful about having an embryo transfer.

embryo-transfer

After the embryo transfer, to support the uterus lining and to ease implantation, a
Progestogen is prescribed. In the past, progestogen is administered by injections. These injections are usually painful and cause local irritations, which is uncomfortable and unacceptable to many. With the advent of effective oral and vaginal suppository preparations, studies had shown that these forms of progestogen are equally effective in delivering progestogen to uterus, injectable progestogen had slowly becoming a thing of the past in many IVF centres. This has also greatly cut down the pain experience in IVF

In conclusion, with rapid modernization in reproductive medicine & technology, IVF had become relatively painless. It is importantly to find out more information on IVF before you embark on this journey.

Is IVF Expensive?

4-prayers-for-when-you-have-no-money-american-bible-society-blog-debt-money-management-broke__grid

 

Question: My Husband & I had been married for 8 years, we have tried many different methods of getting pregnancy with no avail (except IVF). The reason I have not attempted IVF is because I heard that it is extremely expensive with low success rates, is this true?

 

Dr Helena’s Answer: Many people have a lot of myths and misunderstanding about IVF. In fact, IVF started in the 1970’s with many controversies. It used to be regarded as cultic practice in science, intertwined with many religious, social and ethical controversies

However, many years had gone by and IVF had progressed in leaps and bounds in its technology and approach, proving to the world its value and safety. At the turn of this century, reproductive doctors and scientists had achieved many new innovations and breakthroughs, to make IVF more accessible and safer. Hence, IVF had gradually become the mainstream in reproductive science, making the dreams of having children a reality for many couples

However, it is not unusual to find that people are still weary about IVF, and there are still myths and misconceptions surrounding IVF.

One of the myths about IVF is that it’s extremely costly. We hear stories that people had to ‘loose an arm or a leg’ to be able to afford IVF.

The truth is that IVF cost had reduced remarkably for the last 10-20 years, thanks to many creative innovations, especially in the advent of cost effective medications, culture mediums and lab equipments. The advent of a new freezing technique, called vitrification, allows IVF scientists to freeze embryos more effectively to allow storage of excessive embryos, to be used later, cutting down the need to repeat another IVF cycle, making IVF more cost effective.

The cost of IVF in Malaysia is generally ranging between RM12,000-RM20,000. The price range varies because of differences in clinical and laboratory settings, medications used and etc

The success rates are generally good depending on the age of the women. For women aged below 35, the success rate is about 60-80%. For women above the age of 35 but below the age of 40, the success rate is around 50%. The success rate fell dramatically after the women crossed 40 years of age.

There is recent study on Danish population about the cost effectiveness of IVF. The study followed almost 20,000 Danish women undergoing fertility treatments including IVF. Within three years, 65% of the women had given birth, with the figure rising to 71% within five years.

Therefore, it is important to find out more about IVF before deciding on or against it.
