Women’s health questions come in many forms, and few formats answer them as directly as a dedicated mailbag episode. In the 30th installment of the Healthful Woman podcast, Dr. Nathan Fox responded to a wide range of listener-submitted questions covering pregnancy safety, birth planning, fetal growth concerns, and prenatal genetic screening. Whether you are currently pregnant, planning a pregnancy, or simply curious about the evidence behind common recommendations, this episode offers grounded, research-informed perspectives. If any of the topics below relate to your personal situation, consulting with a qualified provider is always the appropriate next step.

Is Teeth Whitening Safe During Pregnancy? What the Evidence Suggests
One of the most common questions in the mailbag episode concerned the safety of teeth whitening products during pregnancy. Dr. Fox addressed this topic by noting that formal clinical research on the subject is limited, which itself is meaningful context for any patient considering this during pregnancy.
Most over-the-counter and professional whitening products rely on hydrogen peroxide or carbamide peroxide as their active ingredients. Because controlled trials on pregnant populations are ethically difficult to conduct, there is no robust body of evidence definitively establishing safety or harm. As a general principle, many providers apply the precautionary approach when evidence is incomplete: if a cosmetic or elective procedure can be postponed until after delivery, that is often the more conservative choice.
Dr. Fox acknowledged that systemic absorption from whitening products applied to tooth enamel is considered low, but emphasized that the absence of confirmed risk is not the same as confirmed safety. This distinction matters in women’s health conversations, particularly when patients are navigating decisions where the stakes involve both maternal and fetal well-being.
What Patients Can Do
Patients with questions about dental care and cosmetic procedures during pregnancy are encouraged to raise them directly with their obstetric provider. The team at Carnegie Women’s Health is partnered with experienced maternal fetal medicine specialists, which means complex questions like these can be addressed within a comprehensive care framework rather than in isolation. Individual medical history, gestational age, and overall health status all inform how a provider approaches these recommendations.
Women’s Health and Vaginal Birth After Multiple Cesarean Sections
Another frequently submitted topic in the mailbag was vaginal birth after cesarean, commonly referred to as VBAC, and specifically whether patients who have had multiple prior cesarean deliveries remain candidates for a trial of labor.
Dr. Fox discussed how the conversation around VBAC has evolved in women’s health practice. While a single prior cesarean was once considered by some to be an absolute barrier to vaginal delivery, evidence now supports that a trial of labor after cesarean, or TOLAC, can be appropriate for carefully selected patients, even those with more than one prior cesarean. The key variables include uterine scar type, surgical history, and institutional capacity to manage potential complications such as uterine rupture.
The uterine rupture risk is central to this conversation. Dr. Fox noted that published data suggest the risk increases with each additional uterine scar, and this risk profile must be weighed carefully against a patient’s individual goals and clinical circumstances. No single answer applies to all patients.
The Role of Shared Decision-Making
Decisions about mode of delivery are among the most consequential in obstetric care. Understanding options for comprehensive women’s health care at Carnegie Women’s Health can help patients approach these conversations with confidence. Carnegie Women’s Health partners with maternal fetal medicine specialists affiliated with Maternal Fetal Medicine Associates, which allows for a level of consultation depth that is particularly valuable in complex delivery planning scenarios. Individual results and candidacy vary based on clinical history.
Reducing Recurrent Intrauterine Growth Restriction: What Research Suggests
Intrauterine growth restriction, or IUGR, refers to a condition in which a fetus does not grow at the expected rate during pregnancy. In the mailbag episode, Dr. Fox addressed questions from listeners who had experienced IUGR in a prior pregnancy and wanted to understand whether steps could be taken to reduce recurrence risk in a future pregnancy.
The causes of IUGR are varied and include placental insufficiency, maternal health conditions, infections, and genetic factors, among others. Because the underlying cause influences both recurrence risk and management strategy, identifying the etiology from a prior pregnancy is an important starting point for planning. Dr. Fox noted that in some cases, low-dose aspirin initiated early in pregnancy has been associated in research with a reduced risk of placental-related complications, including some forms of growth restriction. This is consistent with guidance from major obstetric organizations, though individual recommendations depend on a full clinical assessment.
Prenatal Monitoring and Genetics
For patients with a prior IUGR pregnancy, enhanced prenatal surveillance, including serial growth ultrasounds, is commonly discussed as part of an individualized care plan. Gynecologic ultrasound services are available at Carnegie Women’s Health, and the practice’s affiliation with Carnegie Imaging for Women supports access to specialized imaging when needed. Dr. Fox also touched on the role of prenatal genetic screening in evaluating cases where a genetic etiology may contribute to growth concerns, noting that understanding a patient’s full genetic picture can inform both diagnosis and future pregnancy planning.

Frequently Asked Questions
What is the Healthful Woman podcast and who is Dr. Nathan Fox?
The Healthful Woman podcast is an educational resource focused on women’s health topics, hosted by Dr. Nathan Fox, a maternal fetal medicine specialist. In each episode, Dr. Fox discusses clinical questions, research findings, and patient-submitted topics in an accessible format. The podcast is intended as a general educational resource; listeners are encouraged to consult a qualified provider for guidance specific to their own health history and circumstances.
How do I know if I am a candidate for a VBAC after multiple cesareans?
Candidacy for vaginal birth after multiple cesarean deliveries depends on several factors, including the type and number of prior uterine incisions, overall maternal health, and the capabilities of the delivering facility. Research suggests that some patients with multiple prior cesareans may be appropriate candidates for a trial of labor, but this determination requires a thorough review by an experienced obstetric provider. Individual results and risk profiles vary significantly.
What prenatal genetic screening options are available?
Prenatal genetic screening has expanded considerably in recent years and may include cell-free DNA screening, carrier screening, nuchal translucency ultrasound, and diagnostic testing such as amniocentesis or chorionic villus sampling. The right approach depends on a patient’s age, family history, and prior pregnancy outcomes. Carnegie Women’s Health offers access to genetic screening resources, and the care team can help patients understand their options before testing begins.
Is low-dose aspirin recommended for all pregnancies to prevent growth restriction?
Low-dose aspirin is not universally recommended for all pregnancies. Research suggests it may help reduce the risk of certain placental complications, including preeclampsia and some cases of intrauterine growth restriction, particularly in patients identified as high risk. Major obstetric organizations, including the American College of Obstetricians and Gynecologists, have issued guidance on patient selection criteria. A conversation with your provider is the appropriate first step to determine whether this approach applies to your situation.
