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.
Can IVF Cause Cancer?
Today’s post addresses a question that I am often asked at the clinic – Can IVF cause cancer?
This concern very likely stems from a study done 12 years ago, which has since been well-publicised. It reported that the use of Clomid, which is a fertility medication widely used to treat ovulatory dysfunction in women, might increase the risk of breast and uterine cancer.
Understandably, this has caused some infertility patients to wonder if the treatments they will undergo are safe. Therefore, today I’d like to reassure you by providing references to other studies on the subject.
It’s important to note that since that study was first published, more studies have been conducted and most have found no significant link between Clomid use and cancer risk. One such study, which in fact offers the strongest evidence that Clomid and other ovarian-stimulating drugs do not increase the risk of ovarian cancer, comes from the Cochrane Review.
Published in 2013, the review looked at studies from 1990 to February 2013 that involved 182,972 women. The review not only found no evidence of increased ovarian cancer in women who use any fertility drug, but also pointed out that studies claiming there is an increased cancer risk were unreliable. This is because their sample sizes were too small for drawing conclusions and they did not take into consideration other potential risks for cancer.
For example, if a woman has never experienced pregnancy, her risk of cancer increases. Certain causes of infertility can also cause an increased risk of cancer, for example obesity, PCOS and endometriosis. So in fact, the increased risk of cancer noted in those studies may not be related to the medications at all.
In fact, ironically, some studies showed a decreased risk of developing breast and uterine cancer among infertile women on Clomid, in comparison to infertile women who did not seek treatment for infertility.
There are two other studies, with substantial sample sizes, which included 25,108 women from the Netherlands who received IVF treatment between 1980 and 1995, found that there was no increased risk of breast cancer. Another study, by the Institute of Child Health at University College London, which involved over 250,000 British women undergoing IVF between 1991 and 2010, also found no increased risk of breast or uterine cancer in those patients. However, they learned that IVF patients had a slightly higher risk of ovarian cancer – 15 in 10,000 odds, as compared to women who had never undergone IVF, who had 11 in 10,000 odds.
So as a consensus, from the studies quoted above and others like them, you can rest assured that fertility drugs like Clomid do not increase your risk of developing breast or uterine cancer. However, because infertility itself is a cancer risk factor, it is best that you undergo the necessary follow-up after your infertility diagnosis.
Should you have any concerns on the medications and treatments for infertility, please don’t hesitate to speak to your infertility consultant.
Endometrial scratching to improve IVF success rates
Couples who are struggling with infertility often seek In-Vitro Fertilisation (IVF) treatment in order to improve their chances of starting a family. But what happens when you have gone through multiple unsuccessful IVF cycles? Is there something else you can try?
Many patients who’ve experienced this first hand, have asked me this question, eager to try out something new to enhance their chances in the next IVF cycle. Therefore, today, I’d like to tell you more about a procedure called endometrial scratching, which has become increasingly popular in recent years.
What is it?
Endometrial scratching is a procedure that involves agitation of the endometrium, which is the mucus membrane that lines the uterus. For conception to occur, a fertilised egg has to successfully implant itself into the wall of the uterus. Sometimes, implantation fails, usually due to the quality of the embryo or the receptivity of the endometrium. In endometrial scratching, a fertility specialist passes a special thin catheter or pipille through a woman’s cervix. The pipille is then moved up and down to gently make tiny scratches or scrapes in the uterine lining. The similar effect can also be achieved by introducing a hysteroscope through the cervix to visualised the lining of the uterus during polyps removal.
Why is it done?
In theory, endometrial scratching is believed to trigger the uterus to repair itself and develop a new lining, which will be more receptive to an embryo implanting. While the effectiveness of the procedure needs further investigation, studies that have been done on endometrial scratching in recent years have shown encouraging results.
One such study was conducted by the University of Nottingham, UK, which involved 158 women who had undergone unsuccessful IVF procedures. The women were divided into two groups, with one group given the endometrial scratching procedure. As a result, they found the women who had undergone the scratching procedure achieved a 49% pregnancy rate, compared to 29% in the other group.
In another study involving 1000 women, presented at the annual meeting of European Society of Human Reproduction and Embryology (ESHRE), endometrial scratching is said to increase pregnancy success rates for couples trying to conceive naturally or with Intrauterine Insemination (IUI).
When is it done?
The endometrial scratching procedure is usually recommended for patients who’ve experienced multiple unsuccessful IVF cycles or Intracytoplasmic Sperm Injection (ICSI) treatment. The procedure is best performed prior to a woman’s period or right after the period. It is done before an IVF or frozen embryo transfer (FET) cycle begins.
Does it hurt?
While the endometrial scratching procedure has been described as generally painless, requiring no anaesthetic, some women do experience discomfort during and after the procedure. The pain is similar to period cramps and there may be slight bleeding afterwards. To help with possible discomfort, patients are advised to take over-the-counter pain medication about an hour before undergoing the scratching procedure.
If you’ve gone through several IVF attempts and are keen on learning more about endometrial scratching, take the next step and ask your fertility specialist if it is right for you.

The occurrence of identical twins after a single embryo transfer
Even after many years of being a doctor, it still brings me immense joy to announce to my patient that she is indeed pregnant following a successful infertility treatment. And sometimes, the happiness is multiplied, as there isn’t one, but two buns in the oven!
In general, it is widely known that the occurrence of multiple births is much higher following assisted reproductive technologies (ART) as compared to incidences of twins in natural or spontaneous pregnancies. This is directly related to the number of embryos transferred back to the uterus. In general, if 2 embryos are transferred back into the uterus, the chance of having twin pregnancies is around 20-30%. As we all know, twin pregnancies carries more risks to the expecting mother as well as the babies. The risks of miscarriage, bleeding in pregnancy, high blood pressure, diabetes in pregnancy, Placenta Praevias, Caesarean Sections are some of the significant obstetric risks. The babies are also at risk of preterm births, stillbirths and complications associated with preterm deliveries such as cerebral palsies.
Therefore, in many countries especially in the west, it is mandatory that the patients are informed of these risks before an embryo transfer. Some countries had restricted the number of embryos transferred to one. This move had significantly reduce the incidence of twins following an IVF and had reduced the economic burden associated with medical care of pregnancies associated with twins
However, in recent years, it had been reported that there is a higher incidence of identical twins following single embryo transfer.
While the incidence of fraternal twins following the transfer of two embryos is an easily understandable consequence of IVF, the causes for identical twins after ART remain speculative at best. However, there is some evidence that attributes the phenomenon to the micromanipulation techniques, length of culture and culture medium used during treatment, as well as the genetics of the parents.
Identical twins, also known as monozygotic twinning or MZT, occur when an egg and a sperm unite to form a single zygote that divides into two embryos or separate individuals. It is a rare phenomenon, which occurs in only about 1% of natural conceptions. However, in assisted conceptions, the occurrence of monozygotic twinning almost doubles.
The splitting of the zygote into separate embryos can occur at any time during the first 2 weeks after fertilisation. However, the timing of the split will influence the type of identical twin. For example, in around 1/3 of MZT cases where the split occurs within 72 hours of fertilisation, the result is two placentas and two amniotic sacs. In the remaining 2/3 of MZT cases, the splitting occurs 4-8 days after fertilisation, resulting in one placenta and two amniotic sacs. And in about 5% of MZT cases, where splitting occurs 8-13 days after fertilisation, the outcome is one placenta and one amniotic sac. In very rare cases, the outcome is conjoined twins.
Although the prospect of having twins is certainly exciting, couples must also understand that twin pregnancies are considered high risk. They can lead to various pregnancy complications with long-lasting and even permanent effects for the children. These include caesarean section, premature birth, low birth weight, Twin-Twin Transfusion Syndrome (TTTS), pre-eclampsia, gestational diabetes, fetal abnormalities and congenital abnomalies. In view of the complications that can arise from a twin pregnancy, do speak to your infertility consultant about the risks involved should you have any worries.
