Dr. Yeong Cheng Toh: Why you should always consider IUI before IVF

Did you know? As many as 15%1 of couples in Singapore are unable to conceive within a year of trying for a child. Unsurprisingly, the number of Singaporean parents-to-be opting for IVF continues to climb steadily – from 2013 to 2017 alone, the number of IVF cases jumped from 5,500 to 7,700. 

Getting pregnant is not as easy as most people think, and artificial conception is not able to promise a child; even if success is had, it can often take copious tries, financial sacrifices, and umpteen emotional rollercoaster rides. 

If you’re part of the population that’s desperately trying to conceive, you are not alone. And if you and your partner are considering IVF, you might want to think about going for IUI (intrauterine inseminations) first.

In this article, we cover why IUI could be a great first option for many couples. Additionally, is IUI or IVF the better treatment option for you and your partner? 

Read on to find out more.

What are the fertility treatments available in Singapore?

According to SingHealth, more and more couples are pursuing options such as making lifestyle changes, bettering their diets; reducing stress; opting for Traditional Chinese Medicine (TCM), or even going for fertility wellness staycation in their attempts to conceive. 

Apart from that, fertility treatments in the form of medications are also available for couples hoping to conceive, and are a comparatively inexpensive solution. 

For example, Clomiphene, which is used by women who are unable to become pregnant, works by altering one’s hormonal balance, causing ovulation to occur and preparing the body for conception. We call this ovulation induction. 

The first step that every couple having trouble conceiving should take is consult a trusted gynaecologist. Factors such as age, PCOS, high stress, and other underlying medical conditions can severely affect fertility, and your doctor will be able to help ascertain if you should go down the route of IUI or IVF.

Key Decisions In IUI and IVF Treatment in Singapore

Whether you choose IUI or IVF, there are many key decisions that have to be made by you and your gynaecologist. Let’s take a look at some of them:

Treatment componentIUIIVF
What it entails During IUI, sperm is placed directly into your uterus, reducing the distance sperm has to travel, hence increasing the chances of the sperm reaching your eggs.During IVF, your eggs are retrieved through a quick 10-minute procedure, combined with a sperm, then back into your uterus.
Success rate*15-20%*40-50%*
MonitoringOptional, depending on use of medicationAlways required
MedicationsOption of natural, oral or injectable medicationAlmost always injectable
Surgery requiring anaesthesiaNoYes, for egg retrieval
Location of fertilisationFemale’s bodyLaboratory
Odds of multiplesRisk is managed with close monitoring and low dosagesRisk is nearly eliminated when only one embryo is transferred
Chance for more than one pregnancyNoYes, if embryos are frozen for future pregnancies
Genetic testingNoYes
Procedure lengthApproximately 2 weeksApproximately 3 weeks for fresh transfers (embryos can be frozen for months or years)
Donor egg option**No**Yes**

*Numbers stated are international success rates and highly depend on factors like age, lifestyle and your type of fertility issue. 

**Eligibility to use donor eggs and donor sperm depends on the patient and must adhere to MOH guidelines. Please speak to your doctor to discuss your candidacy.


IUI vs. IVF Cost

The cost of an IUI is significantly less on a per cycle basis. Furthermore, most successful IUIs happen in the first three cycles. Here’s a breakdown of the usual costs involved in both treatments:

ComponentIUI costIVF cost
Base treatment$1,000 – $1,500$12,000 – $15,000
Medications$2,000 – $3,000$3,000 – $5,000
Doctor consultations$1,000 – $1,500$1,000 – $1,500

IUI vs. IVF risks

IUI also poses less risk compared to IVF. Here are a few differences to be aware of:

MultiplesRisk increases with the use of injectable medications, but are minimised with close monitoring and low dosages.By transferring only one embryo, risk is nearly eliminated.
Ovarian hyperstimulationsyndromeA potential side effect with injectable medications. This is rare in IUI due to lower doses.More common due to large doses of injectable medications. This has to be managed with antagonist protocol, a high protein diet, and possibly, acupuncture.
Ectopic pregnancyNo additional risk.2-5% risk. Ectopic pregnancies occur in 1-2% of unassisted conceptions.
Birth defectsNo additional effects without medications. Very slight risk with medications.While evidence remains conclusive, there might be a 1-2% increase of risk compared to unassisted conceptions.
Egg retrieval complicationsNo risksThough rare, bleeding and infection are possible.
Premature birthNo risk.There is a slight risk for premature birth and low birth weight.
Cancer2No risk.No risk.

Should I opt for IUI or IVF first?

While IVF has been shown to produce higher success rates3, generally, it is recommended to start 3-4 rounds of IUI first. This is because IUI is a lot less costly and less invasive. Many underestimate the cost and toll fertility treatments can take on a woman’s body. 

Besides, as someone who’s been carrying out fertility treatments for over 23 years, it’s not as simple as relying on statistics – in order for IUI or IVF to succeed, it depends on the specifics of your body. 

For example – how old are you? Do you have an underlying condition that affects fertility? Does your partner smoke? 

Generally IUI may be a good fit for couples with: 

  • A sperm allergy
  • Ovulatory infertility (eg. PCOS)
  • Mild male factor infertility
  • Ejaculation dysfunction
  • Cervical factor infertility
  • Unexplained infertility
  • The need for donor sperm (eg. single women)

However, I do not recommend IUI as a first line option for couples with: 

  • Uterine abnormalities (eg. Severe endometriosis)
  • Blocked fallopian tubes
  • A history of pelvic infections
  • Poor semen analysis results
  • Good results from a semen analysis and have been trying for a long time to conceive

IUI or IVF, the fertility journey takes time and commitment

Couples seeking fertility treatment must first be ready to accept the inescapable commitment and challenges. Failed IUI or IVF attempts will cost you financially and emotionally. Therefore, it is crucial to have a strong support system and mental preparedness before beginning your fertility journey. 

Fertility treatments are not magic, but it can be dealt with successfully if the right steps are taken, which is why regardless of age, you are encouraged to seek help sooner rather than later.
