How can older women achieve optimal pregnancy preparation? Many career women are unable to conceive during their younger years, leading to advanced maternal age when trying to conceive. While three major challenges typically arise during this process, we believe that with careful preconception health management, older women can still achieve high-quality pregnancy preparation.
Three Major Challenges in Advanced Maternal Age Pregnancy Preparation
Declining ovarian reserve function and reduced fertility
A woman's eggs develop in the womb before birth. At birth, she possesses 1 to 2 million eggs, which gradually decrease over time. By puberty, approximately 300,000 eggs remain.Scientific research indicates that after age 25, the number of basal follicles in a woman's ovaries decreases at an average rate of 0.97 per year. For women over 35, not only does the quantity of eggs decline, but their quality also significantly deteriorates. Consequently, fertility decreases markedly, and the risk of infertility increases.
Increased Miscarriage Rates and Birth Defect Risks
Female eggs are susceptible to damage from external factors, personal health conditions, and unhealthy habits—such as viral infections, radiation exposure, noise pollution, microwave radiation, environmental toxins, smoking, and excessive alcohol consumption. This damage can cause abnormalities in egg meiosis, leading to chromosomal non-disjunction, breaks, or translocations within the cell. Consequently, fetal chromosomal abnormalities may occur.Fetuses with chromosomal abnormalities are highly susceptible to spontaneous termination of development, resulting in miscarriage. Consequently, women of advanced reproductive age face higher miscarriage rates.
Data indicates that miscarriage rates are approximately 12% for women under 35, rising to around 35% for those over 35, and exceeding 40% for women aged 40 and above.If a fetus with chromosomal abnormalities continues to develop and is born, birth defects and chromosomal disorders may occur. For example, Down syndrome (also known as congenital mental retardation) results from chromosomal nondisjunction during the egg's meiosis. Studies indicate that the incidence of Down syndrome is 1 in 1,500 for mothers aged 25–29,1 in 800 for ages 30–34, 1 in 250 for ages 35–39, 1 in 100 for ages 40–44, and 1 in 50 for age 45. Hence, some refer to Down syndrome as "a condition associated with advanced maternal age."
Increased Pregnancy Risks with Age
As women age, their susceptibility to various diseases rises.For instance, approximately 20% of women over 30 have uterine fibroids. Obese women face progressively higher risks of diabetes, hypertension, and other conditions with age, all posing significant threats to maternal and fetal health during pregnancy. Additionally, older mothers are more susceptible to various obstetric complications, such as gestational diabetes and pregnancy-induced hypertension, which severely impact the health of both mother and baby.

Principles for Older Women Preparing for Pregnancy
Once you decide to have a child, conceive as soon as possible.
After deciding to have a child, avoid delay. Otherwise, bodily tissues continue to age, and egg vitality declines, directly affecting embryo quality.
Actively treat existing health conditions
Women over 35 face higher rates of pregnancy-related illnesses, which not only hinder conception but also pose significant risks to maternal and fetal health during pregnancy. Therefore, seek active treatment and achieve full recovery before attempting conception.
Undergo comprehensive health screening before conception
Women of advanced maternal age face higher risks of health complications than younger women. Therefore, both partners should undergo thorough medical examinations before planning pregnancy. Address any identified issues promptly to optimize physical health.
Ensure adequate sleep daily
Sufficient sleep boosts immunity and enhances organ function, particularly within the reproductive system, aiding in the formation of high-quality fertilized eggs.
Ensure adequate nutritional preparation
Consume fresh vegetables, fruits, eggs, milk, lean meat, and other high-quality protein sources daily to build nutritional reserves. Sufficient, high-quality nutrition improves egg quality.
How can older women prepare optimally for pregnancy? Expectant mothers should maintain confidence and approach preparation with optimism.
