Estrogen Balance and Fertility: How High or Low Estrogen Impacts Ovulation, Periods, and Getting Pregnant [EP 52]
Estrogen gets a bad rap in the fertility world. If you’ve ever been told you have “estrogen dominance,” you’ve probably been made to feel like estrogen is the problem — something to suppress, detox, or eliminate. But here’s the truth: estrogen is essential for fertility, pregnancy, and long-term health. We don’t want to get rid of estrogen. We want to help her stay balanced and working with your body, not against it.
In this episode of The Fertility Dietitian Podcast, we’re breaking down what estrogen actually does in the body, how both high and low estrogen can interfere with fertility, and the biggest nutrition and lifestyle factors that influence estrogen metabolism. This is a short but powerful episode that will completely change how you think about estrogen, hormone balance, and what actually supports healthy cycles and implantation.

Estrogen Balance and Fertility
Welcome back to The Fertility Dietitian Podcast. Today we’re talking all about estrogen balance—what estrogen actually does in the body, how both high and low estrogen can impact fertility, and what you can do to support estrogen in a healthy, sustainable way.
Estrogen is often framed as the villain, especially if you’ve been told you have estrogen dominance. But estrogen is essential for fertility, pregnancy, and overall health. The goal is not to eliminate estrogen, but to support balance and help estrogen work with your body, not against it.
What Estrogen Does in the Body
Estrogen plays a critical role in building a healthy uterine lining for implantation. It regulates ovulation timing, supports cervical mucus quality, and contributes to cycle regularity.
Beyond fertility, estrogen supports bone density, heart health, brain function, and mood. When estrogen is too low, too high, or poorly metabolized, fertility outcomes and overall health can suffer.
Estrogen is best described as a “Goldilocks hormone.” Too much or too little can both be problematic. Balance, timing, and metabolism matter more than absolute levels.
Why “Normal” Estrogen Labs Can Still Be a Problem
One of the most common misconceptions is that if estrogen is within the normal lab range, it can’t be causing issues. In reality, estrogen can appear normal on blood work while still being poorly metabolized or out of balance with progesterone.
The estrogen-progesterone relationship plays a major role in PMS, period flow, cycle length, implantation success, and pregnancy maintenance. Progesterone is a key hormone for keeping estrogen balanced, and low progesterone can contribute to symptoms of high estrogen even when estrogen labs look normal.
Signs and Symptoms of High Estrogen
Common symptoms associated with high estrogen include heavy or clotty periods, breast tenderness, PMS or mood swings, fibroids, and infertility.
Healthy menstrual flow is typically smooth and honey-like. Heavy or clotty bleeding can be a sign that estrogen balance or metabolism needs support.
Signs and Symptoms of Low Estrogen
Low estrogen can also interfere with fertility. Symptoms may include night sweats, poor sleep, low libido, vaginal dryness, and difficulty getting pregnant.
Both high and low estrogen can increase time to conception, which is why identifying the root cause of imbalance is essential.
How Nutrition and Lifestyle Influence Estrogen Metabolism
Estrogen metabolism is heavily influenced by nutrition and lifestyle, particularly gut and liver health.
Gut bacteria play a role in whether estrogen is properly eliminated or reabsorbed and recirculated. When gut health is compromised, estrogen that should leave the body can be recycled, worsening symptoms.
The liver is responsible for processing estrogen and requires adequate nutrients to do this efficiently. Protein, fiber, and antioxidants are especially important for supporting estrogen detox pathways.
Blood Sugar, Stress, and Estrogen Balance
Blood sugar instability increases inflammation and insulin resistance, both of which can disrupt hormone signaling and estrogen metabolism.
Over-exercising, under-fueling, and chronic stress can suppress estrogen production, disrupt ovulation, or worsen cycle symptoms. Both underweight and overweight states can interfere with estrogen production and signaling.
The Role of Genetics in Estrogen Balance
Genetics can influence how estrogen is produced and metabolized, including whether it is shuttled down more inflammatory pathways. However, genetics are not destiny.
Nutrition and lifestyle can shift gene expression and significantly reduce risk, even when there is a genetic predisposition. Estrogen balance is not a one-size-fits-all process.
Top Nutrition and Lifestyle Strategies to Support Estrogen Balance
Fiber and probiotic-rich foods support a healthy gut microbiome, including the estrobolome, which plays a direct role in estrogen balance. Vegetables, berries, beans, and fermented foods can help reduce estrogen recirculation.
Reducing exposure to endocrine-disrupting chemicals is another important step. These compounds mimic estrogen in the body, increase estrogen burden, and place additional stress on the liver. Common sources include plastics, fragrances, conventional beauty products, and household cleaners.
Supporting liver function through daily nourishment is key. This is not about detoxes, but about consistently providing the nutrients the liver needs to process estrogen efficiently. High-quality protein is especially important for supporting estrogen metabolism pathways.
Lifestyle Factors That Support Gut and Liver Health
Appropriate exercise, adequate fueling, and good sleep quality support blood flow, gut health, and liver function.
Circadian rhythm also plays a major role. Morning sunlight exposure, reduced screen time, and honoring darkness at night support hormone signaling, gut lining integrity, and overall metabolic health.
A Word on Supplements and Testing
Blindly supplementing to lower estrogen can worsen symptoms, disrupt ovulation, and create new imbalances. Supplements should never be added without understanding what is actually happening in the body.
Blood estrogen levels provide limited insight. They do not show how estrogen is metabolized or why symptoms are present.
Advanced testing, such as the DUTCH test, can provide detailed information about estrogen production, metabolism, and the estrogen-progesterone relationship. This allows for targeted, individualized support rather than guesswork.
Final Thoughts on Estrogen and Fertility
Estrogen is not the enemy. It is essential for a healthy cycle, successful implantation, and long-term health, including bone, brain, and heart health.
The goal is not to suppress estrogen, but to support balance by nourishing the gut and liver and working with your body’s natural physiology.
