Most clinicians know that eggs age. Fewer acknowledge that the uterus ages too.
In reproductive medicine, we often rely on the seed-and-soil analogy. The seed is the embryo. The soil is the endometrium, the inner lining of the uterus where implantation occurs.
Here is the part that deserves more explicit counseling and strategic planning: Even when embryo quality is controlled, uterine age can independently influence implantation, miscarriage risk, and live birth rates. …

Uterine aging in IVF: Why the “soil” matters as much as the seed
Infertility affects one in six people of reproductive age worldwide, yet it remains one of the most overlooked public health challenges of our time. For decades, millions of individuals and couples have navigated this journey in silence, carrying grief, stigma, financial strain, and deep uncertainty about their reproductive futures. Despite its prevalence, infertility has rarely been treated as a global health priority.
That changed this year when the World Health Organization …

Carrier screening has outgrown the language we still use to explain it. The rapid expansion of genetic testing has uncovered new layers of complexity in how conditions present, how results should be interpreted, and how patients experience and act on genetic information. To practice responsibly in this era of Genetic Carrier Screening 3.0, clinicians must understand not only what we are testing for, but how and why the results look …

Why carrier screening results are complex
Carrier screening has outgrown the language we still use to explain it.
For years, clinicians told patients they were either “a carrier” or “not a carrier.” But as the science has evolved, this binary approach is not only outdated; it is increasingly misleading.
Genetic carrier screening has entered a new era, and our counseling must evolve alongside it.
For decades, carrier screening was offered selectively based on ethnicity. Ashkenazi Jewish individuals were screened …

Carrier screening counseling must evolve
As physicians, we’re used to thinking about dose (how much medication, how often, and for how long). But there’s another dimension that’s often overlooked: time. For decades, we’ve known that the body processes medicines differently depending on the time of day. A blood pressure pill or chemotherapy drug can have markedly different effects depending on when it’s taken. This field, known as chronopharmacology, has transformed how we think about drug …

How timing affects chemical exposure risks
A young woman in her late twenties came to me after surgery for extensive endometriosis. The procedure had given her relief; her pain was gone. Her follow-up testing looked reassuring: her fallopian tubes were open on hysterosalpingogram (HSG), and her anti-Müllerian hormone (AMH) level was above 4 ng/mL, which is considered normal. Her question was straightforward: “If my AMH is good and my tubes are open, doesn’t that mean everything …

Endometriosis, AMH, and your fertility
As a reproductive endocrinologist, I see countless patients who walk through my doors with quiet stories of loss—sometimes the loss of hope, sometimes the loss of time. But every year, there’s a particular group of gentlemen who share a strikingly similar history.
They come from different countries. Many grew up in regions where the measles-mumps-rubella (MMR) vaccine was unavailable or inconsistently administered. They had mumps as children, recovered, and thought nothing …

Von Willebrand disease (VWD) is the most common inherited bleeding disorder, affecting approximately 1 percent of the population, though clinically significant symptoms occur in about 1 in 10,000 individuals. It is caused by a deficiency or dysfunction of von Willebrand factor (VWF), a protein critical for blood clotting. For women, VWD poses unique challenges during reproductive years, particularly in the context of fertility and assisted reproductive technologies like in vitro …

Introduction
Endometriosis is a chronic, estrogen-dependent inflammatory disease affecting approximately 10 percent of reproductive-age women and is a leading cause of infertility. Despite its significant impact, it remains underdiagnosed and inadequately managed. This review examines the pathophysiological mechanisms linking endometriosis and infertility, current treatment strategies, and the role of dietary and lifestyle interventions in optimizing reproductive outcomes.
Endometriosis is characterized by the presence of endometrial-like tissue outside the …

Endometriosis and fertility: What every woman should know
At-home hormone testing kits have surged in popularity, offering individuals unprecedented access to tools they believe will help them understand their bodies. Marketed as convenient, empowering solutions to monitor fertility and general hormone health, these tests may seem like a valuable resource at first glance. However, the reality is far more complex. In many cases, these kits create confusion, unnecessary stress, and even lead to harmful interventions.
While the promise of …

The growing concern
In the age of marijuana legalization, a troubling health concern is emerging—its impact on fertility. While cannabis enjoys increased social acceptance, its unintended consequences on reproductive health are often overlooked. Daily marijuana use now surpasses high-frequency alcohol consumption, marking a cultural shift that demands urgent attention. Yet, despite accumulating evidence, why does it feel like no one is listening?
As fertility specialists, we are witnessing an alarming trend: couples …

Why is no one listening? The urgent impact of marijuana on fertility
Introduction
Sleep is not just a luxury; it is essential for maintaining health, and its role in fertility is particularly profound. From regulating reproductive hormones to protecting egg and sperm quality, sleep impacts every stage of the reproductive process. Yet, sleep disturbances—such as insomnia, obstructive sleep apnea (OSA), and irregular schedules—are often overlooked in fertility discussions. Recent research highlights how poor sleep affects fertility in men and women, influencing natural conception …

Epigenetics has revolutionized our understanding of how lifestyle factors—such as diet, stress, exercise, and environmental exposures—affect fertility. Unlike genetic mutations, which change the DNA sequence, epigenetic changes modify how genes are expressed without altering the DNA itself. These changes occur through mechanisms such as DNA methylation and histone modifications, and they play a critical role in fertility. Even more intriguing, these epigenetic changes can be passed down to future generations …

In recent years, e-cigarettes have emerged as a popular alternative to traditional cigarettes, often marketed as a safer choice. However, accumulating evidence reveals that e-cigarettes pose significant risks, particularly to reproductive health. This concern is especially urgent given the ongoing decline in fertility rates across the United States, which have reached historic lows in recent years. As a reproductive specialist, I find it crucial to address these risks and emphasize …

Fertility treatments are a challenging journey filled with emotional highs and lows. For many, these treatments represent the hope of starting or growing a family. However, one of the less obvious but critical aspects of this journey involves pharmacy benefit companies (PBCs). These companies play a significant role in determining access to fertility medications, and their influence can create unexpected barriers for patients and health care providers alike.

Microplastics, tiny plastic particles less than 5 mm in size, have permeated our environment, showing up in oceans, air, and even our food. These particles are a growing concern due to their potential impact on human health and fertility. Recent studies, including one by the American College of Obstetricians and Gynecologists (ACOG), have highlighted the risks associated with microplastic exposure. This article delves into what microplastics are, how they affect …
