Natasha Spencer, MD, highlights advances in obstetric management

In a recent discussion with Contemporary OB/GYN, Natasha Spencer, MD, obstetrician and gynecologist with Orlando Health, highlighted how evolving clinical practices and changing societal trends have improved obstetric care for older women, particularly those aged 35 years and older.

While prenatal care protocols remain largely standard, several advancements and structured guidelines have enhanced safety and outcomes for this demographic. Spencer explained that women of advanced maternal age now routinely receive low-dose aspirin throughout most of their pregnancies—typically until 36- to 37-weeks' gestation—to help reduce the risk of preeclampsia and other complications.

Additionally, noninvasive prenatal screening has become a cornerstone of care. This blood test analyzes fetal DNA fragments circulating in the mother’s bloodstream to detect chromosomal abnormalities such as Trisomy 21, Trisomy 13, and Trisomy 18. Patients are also co-managed with maternal-fetal medicine specialists who perform detailed level 2 anatomy ultrasounds to monitor fetal development and identify any potential structural or soft marker anomalies.

Spencer’s survey findings further reflect a societal shift: more women are choosing to have children later in life. This trend is influenced by multiple factors, including career prioritization, delayed fertility, and the emergence of “second-stage families,” where women who had children earlier in life choose to have more children with new partners after significant time gaps.

However, Spencer noted that misconceptions persist about the risks associated with later pregnancies. Many women approach conception when aged over 35 years with anxiety, fearing complications or infertility.

She emphasized that age alone does not preclude a healthy pregnancy. With proper preconception care—such as managing chronic medical conditions, maintaining a healthy lifestyle, and working closely with an OB-GYN—women in their late 30s and 40s can and often do experience normal, uncomplicated pregnancies and deliveries.

To improve patient understanding, Spencer encouraged clinicians to foster open, proactive conversations about reproductive planning during routine visits. By discussing future family goals early, clinicians can help women make informed decisions and dispel myths about age-related fertility and pregnancy risks.

According to recent data, women in their 40s are now giving birth at higher rates than teenagers—a striking demographic milestone that underscores changing reproductive trends and advances in obstetric care. Spencer concluded that with evidence-based guidance and patient-centered communication, older mothers can approach pregnancy with confidence and optimism.
