IVF Success Rates & Pregnancy in Malaysia

Key Takeaways

• Infertility affects approximately 1 in 6 adults globally, according to the World Health Organization (WHO)
• IVF (In Vitro Fertilisation) is a fertility treatment in which eggs and sperm are combined in a laboratory, and the resulting embryo is transferred into the uterus
• An IVF cycle covers four stages, including fertility consultation, ovarian stimulation and egg retrieval, fertilisation and embryo development, and embryo transfer
• Treatment is personalised based on each patient’s diagnosis; additional procedures such as ICSI and PGT-A are used when clinically indicated
• Success rates depend on factors including age, ovarian reserve, embryo quality, and the treatment approach recommended by your fertility specialist

In-vitro fertilisation (IVF) is a popular treatment option that has helped countless couples around the world overcome their fertility challenges and achieve pregnancies. IVF involves fertilising a woman’s eggs with a man’s sperm in a laboratory to create embryos, which are then transferred into the uterus.

IVF success rates can be calculated in different ways using varying metrics, which is why it’s important for prospective parents to understand these success rates and what they measure.

What Are IVF Success Rates and How Are They Measured?

IVF success rates are typically expressed as a percentage, calculated by dividing the number of successful outcomes by the total number of IVF procedures performed. The most commonly used measure is:

• Clinical Pregnancy Rate: The percentage of IVF cycles resulting in a pregnancy confirmed by ultrasound (usually 6–9 weeks after embryo transfer).

When comparing clinics, it’s important to understand exactly how each one calculates its success rate and what stage of the process that figure reflects, since not all clinics measure or report success the same way.

Primary Factors Impacting Percentage of IVF Success Rates

There are various factors that influence the rate of success for IVF, including:

Age

Women under the age of 35 have a higher chance of success with IVF. As women age, the rate of pregnancies and live births declines progressively. According to the Human Fertilisation and Embryology Authority (HFEA), live birth rates per embryo transferred are 35% for women under 35, declining to 26% for ages 35-37, 18% for ages 38–39, 10% for ages 40–42, and 5% for women over 42.

At Monash IVF KPJ Johor, our clinical pregnancy rates are consistently approximately:

• Below 30 years old: ~60%
• 30–34 years old: ~45%
• 35–39 years old: ~35%
• 40 years old and above: ~20%

*Note: Clinical pregnancy rates are typically higher than live birth rates, as not all confirmed pregnancies result in a live birth.

Success rates can also be significantly improved with PGT-A (Preimplantation Genetic Testing for Aneuploidy), which helps identify normal embryos for transfer, raising success rates to approximately 70% in suitable candidates. Even though success rates are lower for older patients, it remains possible to conceive through IVF. Your specialist will advise on the most appropriate approach for your situation.

Egg quality

The quality of eggs can also influence the success of IVF treatment. Egg quality tends to decline with age, so if you plan to delay pregnancy, do consider egg freezing treatment to increase your chances of success with IVF later on.

Sperm health

According to a study found in PubMed, statistically, more than 48.5 million couples worldwide have been unable to conceive a child for 5 years or longer and approximately 30–50% of infertility cases are caused by male infertility, specifically low sperm quality. Poor sperm quality directly affects the formation of healthy embryos, ultimately reducing the success rates of fertility treatments such as IUI and IVF. A semen analysis provides a clear picture of sperm health before treatment begins.

Previous pregnancies

A 2024 study published in Fertility and Sterility found that women who had one previous live birth were nearly twice as likely to have a successful IVF cycle (odds ratio: 1.97). Even women with a history of miscarriage had better odds than those who had never been pregnant (odds ratio: 1.35). The success rate was also higher in women who previously had a baby through IVF (odds ratio: 1.58).

Top Tips to Improve Your IVF Success Rate

There are practical steps you can take to improve your chances of a successful IVF outcome:

Maintaining a balanced diet

Obesity can affect hormonal balance, egg quality, and reduce the chances of IVF success. A balanced diet and regular exercise can help you maintain a healthy weight and improve your odds.

Avoiding smoking and alcohol

Smoking and alcohol consumption can impact egg and sperm quality, reducing the chances of fertilisation and pregnancy. It’s best for both partners to stop smoking and drinking alcohol at least three months before starting IVF treatment to boost the chances of success.

Managing stress and ensuring adequate rest

Stress and lack of rest can also have detrimental effects on IVF outcomes. Going through fertility treatment can be emotionally demanding, and finding constructive ways to manage that stress is beneficial for both partners. Speaking to a therapist who specialises in infertility issues can help.

Prioritising rest and sleep is also important for hormonal balance. Getting adequate, quality sleep has been associated with better IVF outcomes and improved hormonal regulation throughout a treatment cycle.

Study proved that good sleep quality was associated with higher clinical pregnancy and live birth rates compared to poor sleep. Aim for a consistent sleep schedule before and during your treatment cycle, and let your specialist know if sleep difficulties are affecting you.

Choosing an IVF Centre with High Success Rates in Malaysia

Choosing the right IVF centre for your treatment is the first step towards ensuring a smooth fertility journey for you and your partner.

Realistic Expectations for In Vitro Fertilisation (IVF) Success Rates

IVF success rates vary depending on age, fertility health, and medical history. A consultation with your fertility specialist will help you understand your individual chances of success and set realistic goals before treatment begins.

Things to expect from the IVF process:

• Success rates decline significantly with age: IVF outcomes vary considerably across age groups, and individual fertility profiles affect treatment prospects in different ways. 
• Multiple cycles are common: Many patients require more than one treatment cycle before achieving a successful pregnancy. Cumulative success rates across cycles are higher than per-cycle figures. 
• Not every cycle reaches embryo transfer: Poor ovarian response or no viable embryos can result in a cycle being cancelled. Your specialist will discuss your risk profile and what to expect at each stage before treatment begins.
• Emotional and practical support is available: Our team provides access to psychological support, and both you and your partner are encouraged to seek support at any point during treatment. You do not need to manage this alone.

FAQs about IVF Success Rates in Malaysia

What is the IVF success rate in Malaysia?

IVF success rates in Malaysia vary by clinic, patient age, and treatment type, with clinical pregnancy rates for women under 35 generally between 40% and 55% per embryo transfer cycle.

Does IVF success rate decrease with each cycle?

No, cumulative success rates generally improve with successive cycles, as each cycle provides additional information about your response to stimulation and embryo quality. Patients who do not succeed in the first cycle often do so in the second or third. Your specialist may adjust the approach between cycles based on your results.

How many IVF cycles does it take to achieve pregnancy?

The number of IVF cycles needed varies for each patient, depending on factors such as age, ovarian reserve, embryo quality, and underlying diagnosis. Cumulative success rates improve with each cycle, as each attempt helps our specialists refine your treatment approach.
