Advanced Maternal Age: Definition, Pregnancy Risks After 35 & Fertility Guide
Share
Advanced maternal age refers to pregnancy at age 35 or older. Fertility declines due to reduced egg quality and ovarian reserve, increasing risks of miscarriage, chromosomal abnormalities, and pregnancy complications. In Singapore and globally, early fertility assessment and IVF treatment can help improve pregnancy outcomes, allowing many women to achieve successful pregnancies.
What Is Advanced Maternal Age?
Definition of Pregnancy at Age 35 and Above
Advanced maternal age is medically defined as pregnancy at age 35 or older, according to obstetric guidelines such as ACOG. This classification is based on evidence showing a gradual decline in fertility and increased pregnancy risks with age.
Why Fertility Declines After 35
Fertility declines mainly due to reduced ovarian reserve and lower egg quality, which increases the risk of unsuccessful conception and chromosomal abnormalities.

Miscarriage and Chromosomal Abnormalities
Women aged 35 and above have a higher risk of miscarriage and fetal chromosomal abnormalities due to age-related egg changes.
Gestational Diabetes and Hypertension
Advanced maternal age increases the risk of gestational diabetes and hypertensive disorders during pregnancy.
Preterm Birth and Low Birth Weight
Pregnancies after 35 have a higher likelihood of preterm birth and low birth weight.Fertility Decline After Age 35
Egg Quality and Ovarian Reserve Reduction
Egg quality and ovarian reserve decline with age, reducing natural conception rates.

Fertility Treatment Options After 35 (Singapore Guide)
IVF Treatment and Embryo Transfer
IVF is often recommended when natural conception becomes difficult, especially for women over the age of 35 experiencing age-related fertility decline.
In Singapore, women over 35 are typically advised to seek early fertility assessment if pregnancy does not occur after several months of trying. Fertility clinics evaluate ovarian reserve, egg quality, and overall reproductive health to determine the most suitable treatment plan. Depending on individual conditions, options may include ovulation tracking, IVF treatment, or other assisted reproductive technologies.
Egg Freezing and Fertility Preservation
Egg freezing allows women to preserve younger, healthier eggs for future use, especially for those who plan to delay pregnancy due to personal or medical reasons.
In Singapore, egg freezing has become an increasingly popular fertility preservation option, allowing women to take proactive control of their reproductive timeline.
Recurrent IVF Failure and Fertility Clinics Support
Causes of Implantation Failure
Repeated implantation failure may be caused by embryo quality, uterine environment, or genetic factors.
International Fertility Treatment and IVF Abroad Options
Why Patients Seek IVF Abroad
Some patients seek IVF abroad for access to broader fertility options and advanced reproductive technologies.
Advanced Maternal Age: Frequently Asked Questions

Medical & Pregnancy Care FAQs
Q5: Do women of advanced maternal age need amniocentesis and chromosomal testing?
Prenatal chromosomal screening is recommended for pregnancies at advanced maternal age. Options include NIPT, first-trimester screening, amniocentesis, and chromosomal microarray testing. In Taiwan, subsidies may be available for eligible individuals to reduce the cost of genetic testing. Patients are advised to discuss risks and benefits with their physician before deciding on invasive procedures.
Q6: Can women of advanced maternal age have a vaginal delivery?
If both mother and baby are healthy, vaginal delivery is still possible. However, delivery planning should consider maternal age, pregnancy complications, and fetal condition.
Q7: What are the chances of pregnancy for older women, and is assisted reproduction necessary?
Fertility declines with age, especially after 35 and more significantly after 37. Assisted reproductive technologies such as IVF may improve pregnancy chances depending on individual fertility status.
Q8: At what age does fertility decline the most?
Fertility declines significantly after age 35 and more rapidly after age 37.
Advanced Maternal Age Case Studies｜Overcoming Reproductive Risks Through Integrated Eastern and Western Medicine
Many women preparing for pregnancy at an advanced maternal age encounter significant challenges along their fertility journey, often leading to both physical and emotional exhaustion. However, hope is far from lost. Through its unique integrated Eastern and Western medicine approach, NUWA tailors personalized treatment plans for women of advanced maternal age and has successfully helped countless families achieve their dream of parenthood.
Below, we share two real-life case studies that demonstrate how NUWA has overcome the challenges of advanced maternal age and helped patients welcome new life.
Case 1: Successful IVF Pregnancy at Age 35
Xiao-Qi, a woman over the age of 35, turned to NUWA Fertility Center after experiencing multiple failed IVF cycles at other fertility centers. Her physical condition was complex, including poor circulation, gastrointestinal discomfort, cold extremities combined with internal heat, and overall imbalance—factors that significantly reduced the likelihood of IVF success.
NUWA Fertility Center and NUWA Traditional Chinese Medicine Center team designed a personalized treatment plan that combined traditional Chinese medicine (TCM)—including herbal medicine, acupuncture, and umbilical moxibustion—with advanced Western reproductive technologies.
After three months of integrated TCM conditioning, Xiao-Qi’s health improved exponentially. Her menstrual cycle stabilized, and during IVF treatment, nine embryos were successfully cryopreserved, two of which passed genetic testing. Despite experiencing discomfort after egg retrieval and abnormal indicators in early pregnancy, the integrated Eastern–Western medical team responded promptly to manage these issues. Ultimately, Xiao-Qi achieved pregnancy with a single embryo transfer.
NUWA Healthcare’s integrated treatment model not only delivers strong clinical results for women of advanced maternal age, but also provides emotional reassurance and support during a highly stressful journey. For couples facing age-related fertility challenges, this approach offers a trusted and effective option.
Case 2: One-Time IVF Success at Age 44
A 44-year-old woman previously underwent IVF treatment at another fertility center, where her AMH level was 0.72 ng/mL. Eight eggs were retrieved, resulting in one Day-3 embryo; however, the transfer did not lead to pregnancy. After a period of rest and recovery, she and her husband decided to try again and sought a more suitable treatment plan at NUWA Fertility Taichung.
Before initiating treatment, the NUWA Fertility team conducted an in-depth consultation, discussing strategies such as egg or embryo accumulation, embryo culture duration, and the choice between fresh or frozen embryo transfer. Taking into account her age and ovarian function, the team developed a plan that balanced success rates with overall treatment burden.
After two treatment cycles, a total of nine eggs were retrieved. Two weeks following embryo transfer, pregnancy was confirmed, and subsequent follow-up revealed successful blastocyst implantation.
This case—achieving pregnancy at age 44 through donor-egg IVF in a single attempt—highlights the importance of patient perseverance combined with a highly experienced medical team. It also demonstrates how precise, individualized treatment strategies can significantly improve pregnancy outcomes.
